1. Read about some important scientific discoveries. Match the discovery
and the field of science it
is connected with. There is one extra field
which you should not choose.
1) In 2003, scientists unveiled the most detailed map of the cosmic microwave background – the light emitted by the universe moments after the big bang.
It reveals that only 4% of the universe is ordinary matter. A quarter is dark
matter. The rest is mysterious dark energy
that drives the expansion of the universe.
Field:
2) In 2004, South Korean researchers
claimed to have cloned a human embryo. But the research, led by Woo Suk Huang,
became a scandal when it emerged the results were fabricated.
Field:
3) The
international space station
welcomed its first inhabitants, while missions to the
moon and Mars both detected frozen water. Planet hunters spotted hundreds of
worlds beyond our solar system, including
some that may be habitable.
Field:
4) Work began on the international
thermonuclear experimental reactor in Cadarache, France. The project
aims to generate cheap and plentiful power through nuclear
fusion.
Field:
5) Scientists find evidence that schizophrenia, dyslexia
and Tourette syndrome
are caused by faulty
wiring in the brain. Other
research shed light
on how the brain stores
memories.
Field:
6) The
European Nuclear Research
Organisation near Geneva started up the Large Hadron Collider, the world’s most
powerful particle accelerator. Discoveries at the laboratory will decide the direction of physics for the next two decades.
Field:
7) The
remains of Ardi, a 4.4m year
old female and the oldest putative human ancestor,
left, were unearthed in Ethiopia.
Short for Ardipithecus ramidus, the skeleton
dates back to the dawn of humanity. In 2003, the
remains of a diminutive and hitherto unknown species of human were unearthed on the Indonesian island of Flores.
The discovery of Homo floresien sis, or «hobbit», is regarded as the most important anthropological find in 50 years. Adults
of the species stood
just 1m tall and lived
as recently as 13,000 years
ago.

№ 2. Read an extract from the article ‘Does Modern Technology Affect Teens?’ Six sentences have been removed from the article.
Choose from the sentences
A–G the one which fits each gap
(1–5). There is one extra sentence which you do not
need to use. There is an example
at the beginning (0).
A teen wants to help change the world and
make it a better place to live. To
him, the best way to contribute to these changes is through modern technology.
Before the advent of
the computer, the teens spent much time and effort in using their manual typewriters and had headaches in using
erasing liquids, retyping their works, crumpling their papers and throwing them
to the baskets. The computer changes this.
It shortens their time, saves a lot of money for
supplies and helps create presentations that wowed their teachers.
If the computer affects
the teens, the Internet catapulted the teens in greater heights. The Internet
revolutionized the way teens look at the world and the future. Most
of all, it gives them the opportunity to interact with other teens and discuss
relevant issues making them mature and real decision
makers. The Internet allows them to post comments and sug gestions to various
organizations, government agencies and other concerned personalities. If before the teens had a hard time to criticize government leaders for their shortcomings, mod ern technology had encouraged them to
speak up and be counted. The teen wants to be heard, and they got it!
Another technological breakthrough is the cell phone. Almost every teen owns a cell phone, some the lesser types, others
the most advanced ones. Some TV
networks had programs allotted
for public announcements and interactions, and these teens express
their criticisms, observations and requests for positive actions from the
government. Problems are now attended to, thanks to the teens and their cell phones.
Try imagining of a day
that a teen has to be late because he must go to the library but has no way of
informing his parents except to scamper to the nearest public phone which might
be congested of callers. Or he has to find his way over dusty bookshelves to
look for the needed book. What about those teens who are really shy to stand up during forums,
and instead will opt to keep silent with a big idea buzzing
in his head. What a pity!
These teens really want a change, and modern
technology is the answer. They must not allow
these high tech tools to enslave them,
but rather, utilize
modern technology to its fullest for the good of mankind.

A.
«Internet technology has totally changed
my life. I review my online bank statements,
make transactions and pay bills, all through
online portals. I go shopping
for electronics, books and DVDs all through the Internet. I pay online,
and then I track my shipment online. I log on to the web portal of my
telephone company to review my phone bills, pay them and change or request new
services with a click of the mouse. I practice digital photography and compose music as a hobby and those fields are full of different
technologies to help me direct the images and music.»
B.
«I totally embrace new technology. Because of
broadband Internet, I am able to work from my
bosses’ home or my home and was able to quit a job that I hated
and that kept me stressed out to the max. Because of cell phones,
we are able to forward
the business phones
when we are out or on the
road. Laptop computers also help making the job mobile when necessary. My life
has been improved in many ways since I got on line. I have made many friends
across the south from chatting.
I never would have met any of these people if not for the Internet.»
C.
«I am autistic
but I have struggled to communicate with those around me. I married a young woman, we had kids, and she was
already internet comfortable. I discovered the whole universe of the Internet.
Now I can write, send, and receive,
to and from virtually anyone.
Without this thread of technology I would have remained isolated
and utterly un influential. And, if communication
technology has helped me to this degree, imagine what it has done for those who
are not autistic.»
D.
«I would like to share some interesting things
happening in India. Five years ago, tele phones
in the home were only for the rich. These days getting a phone service is like
getting a pizza. It is that easy. Medical technology in India has developed to
a great level today. Twenty years ago there was no proper drugs for diabetics.
My grandfather died because of it. But today, diabetes is controllable. Lots of
facilities are open. When new technology arrives, there will be positive and negative results.
But positive results
are greater in my opinion.»
E.
«I am a veteran of the U.S. Army. I spent most of my adult life searching for a career in
jobs that had very little
potential for career
opportunities for me. I became
extremely passion ate about
Web development, and it has shaped the rest of my life. I have several of my
own Web sites, as well as sites that I have built, managed and maintained for my employers. Technology in general, and the Internet,
in particular, have inexorably changed
my life and put me on a career path that I would never have
discovered if not for the technological boom of personal computers, the
proliferation of the Internet, my desire to find a better life for myself, and
my dissatisfaction with my current career path.»
F.
«For the past seven years I have worked as an
exploration geologist in Mongolia for a Canadian company. Communication was
always an issue with expatriates working overseas. Satellite telephones have
helped me to keep in touch with my family but the per minute cost prohibited long or chatty calls. Now, I can talk to anyone in the world who has either a phone
or an Internet connection with «voice over IP (VOIP)» Internet telephoning. Now I can call
my mom in Canada from my western
Mongolia ger (round wool tent) field office any time of
the day or night for just eight cents a minute. I can see her face on my laptop as I left her a Web cam
on my last visit home. I can watch live Web
cam video of my eight month old daughter in Mongolia. I can hear her talk into the microphone and see it all in «real time» with a Skype «Voice over IP» Internet telephone system.»
G.
«Technology has changed my family’s and my life.
We have seen many advances in tech nology here in Ethiopia we are happy at home watching satellite
news, films and documen taries, which
keeps us well informed. Mobile
phones have also contributed to changes in our
life, making them easier. My children have their own phones, as do my wife and
I, as well as a fixed landline at home and in our offices. It is wonderful.»
H.
«I have always been a fan of technology, the most
recent item I purchased that has had a major impact on my life and my health is the Apple iPod. I have always known that the only way to lose weight
and maintain it is to eat right
and exercise. I changed my diet but the exer cise was slow to follow. Then my
iPod arrived. All excuses for not to strap on my sneakers and go for a run literally jumped out the
window. I always need music to motivate me, but just the process of selecting a
CD sometimes took so long I had only a few minutes to get ready for work. Or I would listen to the same CD
over and over again until I was not longer motivated during the run. But now
with a full selection of up to 5,000 songs and the ability to download new music, I never get bored and increased my distance from a one mile to three miles a day in just a couple months.
As a result, I lost nearly 30lb and feel great.»

Technophobia
by Katherine Bilsborough
Technophobia – What?
Technophobe:
Someone who does not like, trust, or want to use technology, especially
computers. (Macmillan English Dictionary)
Technophobia is not a new term and technophobes
have existed since the Industrial Revolution and probably for a lot longer
in some shape
or form. Today
we are living in the Age of Technology. Things that were once deemed
Science Fiction are becoming a reality. We either accept these changes and move with the
times or we resist and become technophobes.
Technophobia – Why?
The reality is much simpler
than saying that technophobes fear technological advance. Technophobes are anxious because
the environment in which they live and work is changing. Most phobias are expressed by a strong
physical reaction. People
who are claustrophobic suffer palpitations
and anxiety attacks when they are enclosed in a small area. An agoraphobic
suffers in a similar way if they are exposed to the great outdoors. Technophobes, on the other hand, experience milder symp toms. They
suffer feelings of self doubt and anxiety. They often feel insecure and
obsolete. Some worry that they will lose their job because they cannot keep up
with the times. In more extreme cases, technophobes convince themselves that
technology will take over the world or that humans will be con trolled by computers and robots. At other times they are afraid that if they press the wrong button on
their keyboard, the computer will explode.
Technophobia – Who?
In most cases technophobes belong to older generations who were not
brought up playing with computer games and mobile phones.
They have never sent a text message
or heard of an i pod. Not only do they not possess a DVD, they
still have not worked out how to use their VHS. These examples seem to validate
the old saying: «You can’t teach an old dog new tricks». It is
understandable that technophobia exists. Experts
in the field of technology are becoming younger
and younger. Being taught by somebody who is young
enough to be your grandson goes against the laws of nature. Traditionally
information and knowledge has been passed down from older generations to
younger generations. Young people were taught to respect their elders in part
because of the knowledge they possess. If this system is turned upside
down, then what happens to the respect
for our elders?
Technophobia – The answer.
If ignorance is, in most cases, the cause of technophobia, then it follows
that knowledge and learning is the way to rectify the
situation. What technophobes need is information. Simple computer classes often
prove highly successful, especially where the student groups are made up of
peer groups; like minded people of a
similar age who are willing to learn but who have no desire to be patronised by
fellow students who are twenty
years younger and possibly quicker
on the up take. It is equally
impor tant that groups of technophobes who have decided «to give it
a go» have an appropriate teacher; some body as similar as possible as
themselves in age. Somebody who will send out a message that says «If I can do it, then so can you».

A–I the one which fits each gap (1–7). There is one extra sentence which you do not
need to use. There is an example
at the beginning (0).
The human
species’ use of technology began with the conversion of natural resources
into simple tools. The prehistorical discovery of the
ability to control fire increased the available sources of food and the
invention of the wheel helped humans (0) . Recent
technological developments, including
the printing press, the telephone, and the Internet,
have
lessened physical barriers to communication and (1) . However,
not all technology has been used for peaceful purposes;
the development of weapons of ever increas ing destructive power has
progressed throughout history, (2) .
Technology has affected society and its surroundings
in a number of ways. In many soci eties, technology has helped develop more
advanced economies (including today’s global economy). Many technological
processes produce unwanted by products,
known as pollution, and deplete
natural resources, (3) .
Technology refers to tools and machines (4) . It
is a far reaching term that may include simple tools, (5)
,
or more complex machines,
(6)
. The word «technology» can
also be used to refer to a collection of techniques.
Technology can be viewed as an activity that forms or
changes culture. Additionally, tech nology is the application of math, science,
and the arts for the benefit of life as it is known.
A modern example is the rise of communication technology, (7) .

Light Verse
The very last person
anyone would expect to be a murderer was Mrs.
Avis Lardner. Widow of the great astronaut martyr, she was a philanthropist, an art collector, an extraordinary hostess,
and, every one agreed, an
artistic genius. But above all, she was the gentlest and kindest human being one could imagine.
Mrs. Lardner had received a generous pension, and she
had then invested wisely and well. By late middle age she was very wealthy.
Her house was a showplace, a veritable museum,
containing a small but
extremely select collection of extraordinarily beautiful jew eled objects. She had one of the first
jeweled wristwatches manufac tured in
America, a jeweled dagger from Cambodia, a jeweled pair of spectacles from
Italy, and so on almost endlessly.
All was open for inspection. The artifacts were not
insured, and there were no ordinary security
provisions. There was no need for anything
conventional, for Mrs. Lardner main tained a large staff of robot
servants, all of whom could be relied on to guard every item with imperturbable concentration, irreproachable honesty, and irrevocable efficiency.
Everyone knew the existence of those robots and there
is no record of any attempt at theft, ever.
And then, of course, there was her light sculpture.
How Mrs. Lardner discovered her own genius at the art, no guest at her many
lavish entertainments could guess. On each occasion, however, when her house
was thrown open to guests,
a new symphony of light
shone through out the rooms.
It was for the light
sculpture more than anything else that the guests came.
It was never the same twice, and never failed to explore new
experimental avenues of art. Many people who could afford light consoles
prepared light sculptures for amusement, but
no one could
approach Mrs. Lardner’s expertise. Not even those who considered
themselves professional artists.
She herself was charmingly modest about it. «No,
no,» she would protest when someone waxed
lyrical. «I wouldn’t
call it ‘poetry in light.’
That’s far too kind. At most, I would say it
was mere ‘light verse.'» And everyone smiled at her gentle wit.
Though she was often asked,
she would never
create light sculpture for any occasion
but her own parties.
«That would be commercialization,» she said.
She had no objection, however,
to the preparation of elaborate
holograms of her sculp
tures so that they might be made permanent and reproduced in museums of art an over the world. Nor was there
ever a charge for any use that might be made of her light
sculptures.
«I couldn’t ask a penny,» she said,
spreading her arms wide. «It’s free to all. After all, I have no further
use for it myself.» It was true. She never used the same light sculpture twice.
When the holograms were taken, she was cooperation
itself. Watching benignly at every step,
she was always ready to order her robot servants to help. «Please,
Courtney,» she would say,
«would you be so kind as to adjust the step ladder?»
It was her fashion. She always addressed
her robots with the most formal courtesy.
Once, years before, she had been almost scolded by a
government functionary from the Bureau of Robots and Mechanical Men. «You can’t do that,» he said severely.
«It interferes with their efficiency. They are constructed to follow orders,
and the more clearly you give
those orders, the more efficiently they follow them.
When you ask with elaborate politeness, it is difficult
for them to understand that an order is being given. They react more slowly.»
Mrs. Lardner lifted her aristocratic head. «I do not ask for speed and efficiency,» she said. «I ask
goodwill. My robots love me.»
The government functionary might have explained
that robots cannot love, but he with ered
under her hurt but gentle glance.
It was notorious that Mrs. Lardner never even returned a robot to the factory for adjustment.
Mrs. Lardner shook her head. «Once a robot is in
my house,» she said, «and has performed his duties, any minor eccentricities must be borne with. I will not have him manhandled.»
It was the worse thing possible to try to explain
that a robot was but a machine. She would say very stiffly, «Nothing that
is as intelligent as a robot can ever be but a machine. I treat them as people.»
She kept even Max, although
he was almost helpless.
«But why not have him adjusted?» asked a friend,
once.
«Oh, I couldn’t. He’s himself. He’s very lovable,
you know.»
«But if he’s maladjusted,» said the friend, looking at Max
nervously, «might he not be dan gerous?»
«Never,» laughed Mrs. Lardner. «I’ve had him for years. He’s completely harmless
and quite a dear.»
Actually he looked like all the other robots, smooth,
metallic, vaguely human but expres sionless.
To the gentle Mrs. Lardner, however, they were all individual, all sweet,
all lovable. It was the kind of woman she was.
How could she commit
murder?
The very last person
anyone would expect
to be murdered would be John Semper
Travis.
He was chief engineer
of U.S. Robots
and Mechanical Men, Inc.
But he was also an enthusiastic amateur in light
sculpture. He had written a book on the subject, trying to show that the type of mathematics he used in working out positronic brain paths might be modified
into a guide to the production of aesthetic light sculpture.
His attempt at putting theory
into practice was a dismal
failure, however. The sculptures
he himself produced, following his mathematical principles, were stodgy,
mechanical, and uninteresting.
It was the only reason for unhappiness in his quiet,
introverted, and secure life, and yet it was
reason enough for him to be very unhappy indeed. He knew his theories were
right, yet he could not make them work. If he could but produce one great piece of light sculpture.
Naturally, he knew of Mrs. Lardner’s light sculpture. She was universally hailed as a genius, yet Travis knew she could not
understand even the simplest aspect of robotic mathe matics. He had corresponded with her but she consistently refused to explain
her methods, and he wondered if she had any at all. Might it not be mere intuition? But even intuition
might be reduced to mathematics. Finally
he managed to receive an invitation to one of her parties. He simply had to see her.
Mr. Travis arrived rather late. He greeted Mrs.
Lardner with a kind of puzzled respect and said, «That was a peculiar robot
who took my hat and coat.»
«That is Max,»
said Mrs. Lardner.
«He is quite maladjusted, and he’s a fairly old
model. How is it you did not return it to the factory?»
«Oh, no,» said Mrs. Lardner.
«It would be too much trouble.»
«None at all, Mrs. Lardner,» said Travis.
«You would be surprised how simple a task it was. Since I am with U. S.
Robots, I took the liberty of adjusting him myself. It took no time and you’ll find he is now in perfect working
order.»
A queer change came over Mrs. Lardner’s
face. Fury found a place on it for the first time in her gentle life.
«You adjusted him?» she shrieked. «But it was he who created
my light sculptures. It was
the maladjustment, the maladjustment, which you can never restore,
that that «
It was really unfortunate that she had been showing
her collection at the time and that the jeweled dagger from Cambodia

OK, here’s my new computer. As you can see, there are five main parts. Now, the large box with the slots and sliding disk carrier (1) ________________ is the most important part. It carries all the stuff that makes the computer work (2)_______________. You can also put in (3)_______________ your own games and other things (4)_______________. Next to it there is the thing that looks like a small television (5)_______________ so that you can see what the computer is doing. To the right of that, there is the machine that lets you make black and white or colour copies of the documents that you create on the computer (6)_______________. You can control the computer by using the rectangular flat thing with all the letters and numbers on (7)_______________ or the funny little object with the long lead which you can move across your desk (8)_______________. The large flat thing to the left of the computer is the machine you can use to make copies of your photographs onto the computer, a bit like a photocopier (9)_______________.
It’s a very useful machine, of course. Once you get it up and running (10)__________ you can do lots of things on it. You can create documents, play games or get information from the fantastic thing that links computers from around the world (11)_______________. A lot of companies and organizations have their own special computer page (12)_______________ which you can look at, and you can transfer (13)_______________ the information to your own computer files. Or, if you like, you can send messages to other people by using a special electronic letter-sending facility

Unfortunately, I can’t let you use it as it stopped working (15)_______________ last night. It’s probably got a technical fault, usually created on purpose, that affects computer files and folders

C. Now look at this essay and fill in the gaps with one of the words or expressions from Tasks A and B. In some cases, more than one answer may be possible. You may need to change some of the word forms.
Technology has come a long way in the last fifty years, and our lives have become better as a result. Or have they?
The second half of the twentieth century saw more changes than in the previous two hundred years. Penicillin has already been 1__________________________ and used to treat infections; there have been many remarkable advances in medicine that have helped to increase our average 2__________________________ way beyond that of our ancestors. Incredible 3__________________________
such as television have changed the way we spend our leisure hours. Perhaps the most important 4__________________________ , however, has been the microchip. Nobody could have imagined, when it was first 5__________________________ , that within a matter of years, this tiny piece of silicon and circuitry would be found in almost every household object from the kettle to the video recorder. And nobody could have predicted the sudden proliferation of computers that would completely change our lives, allowing us to access information from the other side of the world via the 6__________________________
or send messages around the world by 7__________________________ at the touch of a button. Meanwhile, 8__________________________ into other aspects of information technology is making it easier and cheaper for us to talk to friends and relations around the world. Good news for 9__________________________ who love modern technology, bad news for the 10__________________________ who would prefer to hide from these modern miracles.
But everything has a price. The development of 11__________________________ led to mass automation in factories, which in turn led to millions losing their jobs. The genius of Einstein led to the horrors of the atomic bomb and the dangerous uncertainties of 12__________________________ (we hear of accidents and mishaps at nuclear power stations around the world, where 13__________________________ to prevent accidents were inadequate). The relatively new science of 14__________________________ has been seen as a major step forward, but putting modified foods onto the market before scientists had properly 15__________________________ them was perhaps one of the most irresponsible decisions of the 1990s. Meanwhile, pharmaceutical companies continue to 16__________________________ on animals, a move that many consider to be cruel and unnecessary.
Of course we all rely on modern science and technology to improve our lives. However, we need to make sure that we can control it before it controls us.

C. Now complete this article with one of the words or expressions from Tasks A and B. In some cases, more than one answer may be possible. You may need to change some of the word forms.
Most children enjoy eating 1____________________ , but scientific tests have shown us that burgers and pizzas can lack essential 2____________________ and 3____________________ which are essential for health and growth, while simultaneously containing large amounts of 4____________________ and 5____________________ which can result in obesity and heart problems. Many children end up suffering from 6____________________ , since they eat too much of the wrong sort of food. In fact, in many areas of the developed world, a lot of children show similar symptoms to those in poorer developing countries, where 7____________________ of food causes thousands of deaths from starvation, especially in the wake of natural disasters which ruin crops and in some cases totally destroy the annual 8___________________ .
Dieticians tell us that we must eat a 9____________________ , as it is essential we consume sufficient quantities of the different food groups. They tell us that we should all eat more 10___________________, which cannot be digested by the body, and fewer foods which are high in 11____________________ , as this can block the walls of arteries and lead to heart problems. This is good advice, of course, but our lifestyles often make this difficult. Many of the ready-prepared foods we buy from supermarkets are high in 12____________________ , giving us more energy than we actually need. 13____________________ foods are appearing on our supermarket shelves, even though nobody is really sure if altering the composition of food cells is safe. We have the option, of course, of buying 14____________________ foods, but naturallycultivated fruits and vegetables are expensive. And to make matters worse, we are continually hearing about outbreaks of 15____________________ and 16____________________ which put us off eating certain foods, as nobody wants to spend time in hospital suffering from 17____________________ .
A few things to watch out for next time you go shopping. If you have the time and the money, that is!

Welcome to VOCABULARY IN CONTEXT!
A well-developed vocabulary pays off in many important
ways. Better-than-average “word power” makes it easier to
understand everything you read and hear—from textbook
assignments to TV news reports or instructions on how to repair
a bicycle. And word power obviously increases your effectiveness
as a communicator. Think about it: As far as other people are
concerned, your ideas are only as convincing as the words you
use to express them. In other words, the vocabulary you use when
you speak or write always significantly adds to or detracts from
what you have to say.
VOCABULARY IN CONTEXT was written especially for you.
The program was designed to enrich your personal “word bank”
with many hundreds of high-frequency and challenging words.
There are six thematic books in the series— Everyday Living ,
Workplace and Careers , Science and Technology , Media
and Marketplace , History and Geography , and Music, Art,
and Literature. Each worktext presents topic-related readings
with key terms in context. Follow-up exercises provide a wide
variety of practice activities to help you unlock the meanings of
unfamiliar words. These strategies include the study of
synonyms and antonyms; grammatical word forms; word
roots, prefixes, and suffixes; connotations; and the efficient
use of a dictionary and thesaurus. Thinking skills, such as
drawing conclusions and completing analogies, are included
as reinforcement.
A word of advice: Don’t stop “thinking about words” when
you finish this program. A first-class vocabulary must be
constantly renewed! In order to earn a reputation as a first-
rate communicator, you must incorporate the new words you
learn into your everyday speech and writing.
INTRODUCTION

How Does Sunlight Produce Vitamin D?
WORD SEARCH
1. What eight-letter word in the reading means
“the smallest particle of a substance that can
exist alone without losing its chemical form”? _____________________
2. What three organs of the human body are named in the reading?
___________________ ____________________ ____________________
3. What nine-letter word in the reading means
“food” or “nourishment”? ____________________
4. What two-syllable word in the reading means
“to attract and take in another substance”? ____________________
Vitamin D is a chemical that allows
your body to make use of an
important nutrient called calcium. Our
bodies make the Vitamin D we need
by “doing chemistry.”
Sunlight is a part of the chemical
reaction that makes Vitamin D. When
it’s in your skin, the ultraviolet energy
in sunshine snips up another chemical
that is already floating around in your
body. The new chemical formed is
called Vitamin D3. But your body can’t
make use of Vitamin D3 until a few
more chemical reactions occur. So the
D3 is carried to your liver, where the
atoms are rearranged to form a new
molecule. Then that chemical ends up
in your kidneys. There it is taken apart
again and put back together as
calcitrol. This is the Vitamin D your
stomach needs to absorb calcium.
Vitamin D is essential to everyone’s
nutrition. It helps young people grow
strong teeth and straight new bones.
It keeps older people’s bones from
getting brittle. Years ago, parents were
concerned about the lack of sunshine
in the dark winter months. They
worried that their children weren’t
getting enough Vitamin D. Today,
Vitamin D is added to almost all milk
that’s sold in the United States.

Lesson 3
All four terms refer to the
conditions of a large body of water’s
surface. The generic term wave refers
to the undulations of the water’s surface.
In their graceful rise and fall, waves
are a combination of sea and swell.
Swell results from the wind’s past
action on the water. It has a gentler,
more rolling action than that of a
wave. You can see swells in the open
water even when the current wind is
calm. The distance between successive
crests is called the wavelength.
Sea refers to the distinct features
of the wave—such as crests—caused
by wind blowing across the water’s
surface.
WORD SEARCH
1. What ten-letter noun in the
reading means “the surface
features of a region, including
hills, rivers, roads, etc.”? _____________________________
2. What ten-letter adjective in the
reading means “going in regular
order without a break”? _____________________________
Surf is the interaction of the waves
and the shoreline. It is influenced by
the height and energy of the waves.
The topography of the coast also
affects surf. A beach with a gentle,
offshore slope, for example, will have
small surf. A beach that drops off
sharply will have larger surf.

skeleton as a symbol of death. But
each and every bone is a living
organ, full of dynamic vitality. In
fact, every square inch of your
skeleton is regenerated every
ten years. Some parts—the
spongy bones of the spine
and hip—renew themselves
much more often.
In a broader sense, human bone
is a key to understanding who we
are as a species. The bones of long-
dead creatures that have turned to
fossils tell us much about life. Without
them, scientists would know very
little about the history of vertebrates
over the past 600 million years.
Living cells make up less than five
percent of your body’s bones—but they
are continually busy! At this very
moment, specialized cells in your
skeleton are chewing up old, worn-
out bits of bone and putting fresh
new material in their place.
Meanwhile, these same busy
bones are turning out new blood
cells. And they’re making sure
that every part of your body
gets just the right amount of
calcium to keep it going. How do
your bones do this? They act as a
storage bank for calcium. In fact, 99
percent of the calcium in your body is
held in bone—ready for release into the
bloodstream as needed.

Lesson 5
Science in the News: A Very Long-Term Experiment
Seeds buried by a
botanist 121 years
ago have recently
bloomed into bright
yellow flowers.
In the late 1800s,
William Beal was
a botany professor
at Michigan State
University. In 1879, he devised an
experiment to determine how long
seed would continue to germinate. To
do this he put seeds of mullein plants
in 20 glass bottles and then buried
them on the campus.
Professor Beal directed that one
bottle should be unearthed every five
years. To extend the experiment, the

university teacher of the highest rank”? _______________________
2. What eleven-letter compound word in the
reading means “glass buildings that can be
heated for growing plants”? _______________________
3. What ten-letter noun in the reading
means “a test to find out whether a theory
is correct”? _______________________
intervals were lengthened to every ten
and then every 20 years.
The fifteenth bottle was dug up on
an April day in the year 2000. The
1,050 seeds in the bottle were set out
in a growth chamber. Twenty-five
seedlings, nearly all of them mullein,
began to grow.
Put in greenhouses, the plants
soon started blooming. The bright
yellow flowers were described as
“beautiful” by botanists following
through with Professor Beal’s
experiment.
Five of William Beal’s bottles still
remain buried on the Michigan State
campus. The next one is scheduled to
be dug up in 2020.

Better-than-average “word power” makes it easier tounderstand everything you read and hear—from textbookassignments to TV news reports or instructions on how to repaira bicycle. And word power obviously increases your effectivenessas a communicator. Think about it: As far as other people areconcerned, your ideas are only as convincing as the words youuse to express them.
In other words, the vocabulary you use whenyou speak or write always significantly adds to or detracts fromwhat you have to say.VOCABULARY IN CONTEXT was written especially for you.The program was designed to enrich your personal “word bank”with many hundreds of high-frequency and challenging words.There are six thematic books in the series—Everyday Living,Workplace and Careers, Science and Technology, Mediaand Marketplace, History and Geography, and Music, Art,and Literature. Each worktext presents topic-related readingswith key terms in context.
Follow-up exercises provide a widevariety of practice activities to help you unlock the meanings ofunfamiliar words. These strategies include the study ofsynonyms and antonyms; grammatical word forms; wordroots, prefixes, and suffixes; connotations; and the efficientuse of a dictionary and thesaurus. Thinking skills, such asdrawing conclusions and completing analogies, are includedas reinforcement.A word of advice: Don’t stop “thinking about words” whenyou finish this program. A first-class vocabulary must beconstantly renewed! In order to earn a reputation as a firstrate communicator, you must incorporate the new words youlearn into your everyday speech and writing.4SCIENCE AND TECHNOLOGY WORDSUNIT 1PREVIEWHere’s an introduction to the vocabulary terms, skills, and concepts you will study inthis unit.
