完形填空。     Sometimes people call each other "scared-cat",but have you ever thought about this expression?
When a cat is frightened,its heart starts beating faster,its muscles get tense,and there are changes in
the chemicals in its blood- stream.
    Although the cat doesn"t   1   this,its body is getting ready for action.
    If the danger continues,this animal will do one of the two things .It will   2   itself,or it will run
away as fast as it can.
       3 ,when people are excited,angry,scared,or aroused by other emotions,our bodies also go
through many   4   changes. Our hearts beat faster,and our muscles get tense. All of these changes
make us more alert and ready to react. We,too,get ready to defend ourselves  5 run.
     Human beings,  6   ,have a problem that animals never face. If we give way to our feelings and
let them 7 ,we can get into trouble. Have you ever said something in anger,or hit somebody and
regretted it later? Have you ever shouted at a teacher,told someone you were lonely,or said you were
in love,and then   8   later you had kept your mouth shut? It isn"t always   9   to express your feelings
freely.
     Does this mean that it"s smarter always to   10   our feelings? No! If you   11   feelings of anger,
sadness,and bitterness hidden away or bottled up inside,your body stays   12  .Physical illnesses can
develop It can actually be   13   for your health.
     Feelings that you keep all bottled up inside,don"t just   14  .It"s like you bought some bananas and
stuck them in a cupboard. You might not be able to see them,but   15   you"d smell them. And if you
opened the cupboard,you"d   16   little fruit flies hovering (盘旋) all over them. They"d be rotten.
     You can try to treat emotions   17   they were bananas in the cupboard. You can  18   they don"t
exist, but they"ll still be   19  .And at last you"ll have to   20   them. Just like those bananas.

     Introductory Chemistry was taught at Duke University for many years by professor Bonk.
One year,two guys took the class and did pretty well on all the quizzes and mid terms. They
each had a solid A. These two friends were so confident in going into the final that the weekend
before finals week,despite the Chemistry final being on Monday,they decided to go to the University
of Virginia to party with some friends.
    They had a great time there. However,with their hangovers(宿醉) and tiredness,they overslept
all day Sunday and didn"t make it back to Duke until early Monday morning. Rather than taking
the final then,they found professor Bonk after the final and explained to him how they missed the
final. They told him they went up to the University of Virginia for the weekend and had planned to
come back in time to study,but they had a flat tire on the way back and didn"t have a spare. So
they were late getting back to campus.
    Bonk thought this over and agreed that they could take the final the following day. The two
guys,happily and relieved,studied that night and went in the next day at the time that Bonk had
told them. He placed them in separate rooms and handed each of them a test booklet. He told
them to begin.
    They looked at the first problem which was something simple about solution(溶解).It was worth
5 points. "Cool," they thought,"this is going to be an easy final". They then turned the page. They
were unprepared,however,for what they saw on it. The question contained only two words:
(95 points) Which tire?

     Both warm-blooded and cold-blooded desert animals have ways to escape the desert heat.
Warm- blooded desert animals, such as rats and mice, rest during the day, often staying in cool
underground burrows. At night they search for food. Animals that are out during the day, such as
cold-blooded lizards and snakes, are active only for short periods. As their body temperature rises,
these reptiles(爬行动物) move into the shade in order to cool down. In the early evening, when
the sun grows weaker, the reptiles become more active and begin their search for food again.
     Getting enough water to survive is a major problem for all desert animals. Some desert animals,
like desert birds, manage to find water holes. Other desert animals, such as the kangaroo rat and the
related jerboa, get water only from the food that they eat. Because these animals eat mainly dry seeds,
they must survive on a tiny amount of water.
     Most deserts have only a small number of frogs and toads because these animals must be near
water to survive. Yet even these creatures have adapted(适应) to desert conditions. When small
amounts of water collect in temporary streams, the desert-living frogs and toads become active.
After a rainfall, they lay their eggs. The eggs grow into tadpoles in a few days and into adults in just
four weeks. When the puddles(水坑) dry up, the adult frogs or toads dig into the ground. Their metabolism(新陈代谢) slows, and they stay beneath the ground until the next rain, which may be as good as
a year away. Until then, their bodily activities continue at a reduced rate.
    The camel - often called the ship of the desert - is one of the most successful desert animals. Camels
can go for long periods without water, but eventually they must drink. When water becomes available
to them after a long drought, they may drink 95 liters of water or more. When water is not available,
what helps camels survive the desert heat is the fat stored in their humps(驼峰). A camel"s hump contains
about 12 kilograms of fat. Fat is rich in hydrogen. As the fat is digested, hydrogen from the fat combines
with oxygen in the air that the camel breathes. The result is H2O, or water. Each kilogram of fat that a
camel digests produces about a liter of water.

1. Desert animals are usually more active at night because _____.

A. it is cooler at night
B. it is easier to find water
C. they like the dark
D. they are less likely to be attacked at night

2. Which of the following desert animals can get water only from the food?

A. The camel.
B. The kangaroo.
C. The frog.
D. The rat.

3. Which of the following is TRUE according to the passage?

A. All the desert animals rest during the day.
B. All the desert animals don"t rest during the day.
C. Cold-blooded desert animals are out most of the day.
D. None of the cold-blooded desert animals go out during the day.

4. The title for this passage could probably be _____.

A. Hot Deserts
B. Desert Animals
C. How Desert Animals Get Water
D. Ways To Escape the Desert Heat

5. The underlined word "burrows" in the first paragraph can be replaced by _____.

A. holes
B. caves
C. rooms
D. openings

     Millions of years ago dinosaurs lived on the earth. In the days of dinosaurs, the whole earth was warm
and wet. There were green forests and they could find enough to eat. Later, parts of the earth became cold and dry, and the forests there died. Then dinosaurs could not find enough to eat. This must be one reason why dinosaurs died out.

strong. They could kill dinosaurs.
     There may be other reasons that we don"t know about yet. Scientists are are trying to make more
discoveries about dinosaurs. Dinosaurs were of many sizes and shapes. Some were as small as chickens, while some were about 90 feet long.
     There were also terrible rights between dinosaurs. They night have happened more than 100 million
years ago. Though there was no man to see any of the fights, we can be told by the animal"s footprints
(足迹) that fights did take place.

     The blue tits (山雀) have been inspecting the nest-box again this year. The male is the house-hunter but the female will make the final choice. He lands at the hole and turns his head to expose his white cheeks as a signal to attract the female from where she has been feeding. Among many birds that nest in holes, the
male has a light-coloured patch on its plumage (鸟羽) which acts as signal for drawing the female"s
attention to a suitable nesting-place. Unlike the blue tit, the redstart (红尾鸲) may be only the male that
strikingly coloured and the female is not beautiful.
     A few years ago I was lucky enough to spot a pair of redstarts in action in a Walsh wood. The male
was leading an interested female to holes that he had previously (先前) checked out. He sat at the
entrance of each hole and put his head on to show off his white forehead, or his head in to reveal (显露)
his tail.
     If the female failed to react to his visual signals, the male sometimes sang for extra effect, while gliding towards her on spread wings and tail. Once the female accepts by following the male through the hole the
displays stop, you must be at the right place at the right time to watch them.

1. How do the blue tits choose their nest?

A. They choose their nest together.
B. The male chooses their nest.
C. The house-hunter chooses their nest.
D. The female chooses their nest.

2. The writer was lucky to see _____.

A. how the male made his tricks
B. how an interested female played with the male happily
C. what the male displayed and won the female
D. that the male tried his best but failed to attract the female

3. You can spot a pair of redstarts in a Walsh wood _____.

A. at any time
B. regularly
C. in April
D. occasionally

4. The writer is probably _____.

A. a bird expert
B. a bird-hunter
C. a bird raiser
D. a scientist
