What will man be like in the future - in 5,000 or even 50,000 years from now? We can
only make guesses, of course, but we can be sure that he will be different from what he is
today, for man is slowly changing all the time.
     Let us take an obvious example. Man, even five hundred years ago, was shorter than he
is today. Now, on average, men are about three inches taller. Five hundred years is relatively
a short period of time, so we may suppose that man will continue to grow taller. Again, in the
modern world we use our brains a great deal. Even so, we still make use of only about 20%
of the brain's capacity(容量). As time goes on, however, we shall have to use our brains more
and more, and finally we shall need our brains more and more, and finally we shall need larger
ones! This is likely to bring a physical change too: the head, in particular the forehead, will grow
larger.
      Nowadays our eyes are in constant use. In fact, we use them so much that very often they
become weaker and we have to wear glasses. But over long period of time it is likely that man's
eyes will grow stronger.
     On the other hand, we tend to make less use of our arms and legs. These, as a result, are
likely to grow weaker. At the same time, however, our fingers will grow more sensitive because
they are used a great deal in modern life.
     But what about hair? This will probably disappear from the body altogether in course of time
because it does not serve a useful purpose any longer. In the future, then, both sexes are likely
to be bald.
     Perhaps all this gives the impression that future man will not be a very attractive creature to look
at! This may well be true. All the same, in spite of all these changes, future man will still have a lot
in common with us. He will still be a human being, with thoughts and motions similar to our own.

     If you have to miss a meal a day, which meal will cause you fewest health problems if you
don't eat it? If you have to make a decision of this type, most people (especially very busy
people) will choose to skip breakfast.
     However, many experts in the field of health consider breakfast ( the meal which "break"
you "fast" ) to be the most important t meal of the day. If we eat a good breakfast, they say,
we will have the energy and nutrients (营养) we need to begin our working day with vigor(活力)
and stay hopeful with good honor. However, many people skip breakfast or substitute a cup
of coffee for a well balanced meal. What happens if we ignore the importance of breakfast?
     One recent study conducted in the United States tested a large number of people. Participants
included both males and females who ranged in age from 12 to 83. The results showed that if a
person eats an adequate breakfast, he or she will work more efficiently and more productively
than if he or she skips breakfast or eats a very poor breakfast. This fact appears to be especially
true if a person's work involves mental(脑力的) activities. The study showed that if school-children
eat fruit, eggs, bread and milk before going to school, they will learn more quickly and will be able
to concentrate (集中)on their lessons for a longer period of time than if their breakfast is inadequate.
      The study also showed that contrary to what people believe, if you skip breakfast, you will not
lose weight. This is because people become so hungry if they skip breakfast that they eat too much
for lunch and end up gaining weight instead of losing. So remember, if you want to lose weight,
skipping breakfast will not help you. You will likely lose more weight if you decrease your other
meals.

1. According to experts, breakfast is the most important meal of the day because _____.

A. a good breakfast breaks you down fast
B. you'll lose weight quickly if you skip breakfast
C. breakfast provides what a person needs to work

B. To drink a cup of coffee instead of a well balanced meal.
C. To change a cup of coffee into a well balanced meal.
D. To regard a cup of coffee as a well balanced meal.

3. The example of school-children in para.3 shows that _______.

A.school-children will be quick and attentive all day if they eat breakfast
B.a proper breakfast will make mental workers more efficient
C.fruit, eggs, bread and milk are the best breakfast for mental workers
D.school-children who have breakfast are much brighter than those who don't

     It is difficult for doctors to help a person with a damaged brain. Without enough blood, the
brain lives for only three to five minutes. More often the doctors can't fix the damage. Sometimes
they are afraid to try something to help because it is dangerous to work on the brain. The doctors
might make the person worse if he operates on the brain.                                                            
     Dr. Robert White, a famous professor and doctor, thinks he knows a way to help. He thinks
doctors should make the brain very cold. If it is very cold, the brain can live without blood for
30 minutes. This gives the doctor a longer time to do something for the brain.                                  
      Dr. White tried his idea on 13 monkeys. First he taught them to do different jobs, then he
operated on them. He made the monkeys' blood go through a machine. The machine cooled
the blood. Then the machine sent the blood back to the monkeys' brains. When the brain's
temperature was 10°C, Dr. White stopped the blood to the brain. After 30 minutes he turned
the blood back on. He warmed the blood again. After their operations the monkeys were like
they had been before. They were healthy and busy. Each one could still do the jobs the doctor
had taught them.       

1. The biggest difficulty in operating on the damaged brain is that _______.         

A. the time is too short for doctors
B. the patients are often too nervous
C. the damage is extremely hard to fix
D. the blood-cooling machine might break down

2. The brain operation was made possible mainly by _______.

A. taking the blood out of the brain       
B. trying the operation on monkeys first
C. having the blood go through a machine    
D. lowering the brain's temperature

3. With Dr. White's new idea, the operation on the damaged brain _______.

A. can last as long as 30 minutes        
B. can keep the brain's blood warm
C. can keep the patient's brain healthy    
D. can help monkeys do different jobs

4. What is the right order of the steps in the operation?
a. send the cooled blood back to the brain
b. stop the blood to the brain
c. have the blood cooled down
d. operate on the brain

A. a, b, c, d            
B. c, a, b, d       
C. c, b, d, a            
D. b, c, d,

     Putting in water fountains (饮水器) at schools, and teaching children about the health
benefits of water, could reduce their risk of getting extra pounds, reports a new study that
is published in the latest issue of the journal Pediatrics.
      The findings are based on a survey in 32 elementary schools of two German cities, Dortmund
and Essen. The researchers, led by Rebecca Muckelbauer, a nutritionist(营养学家) at the
Research Institute of Child Nutrition Dortmund, weighed about 3,000 children, and asked
them about their beverage consumption(饮料消费量). 
     At the beginning of the school year, the experts had water fountains added to 17 of the schools.
The scientists also worked with teachers to carry out educational programs that promote the
benefits of drinking water. In contrast to schools in the United States, there are very few
schools in Germany that have water fountains.
     At the beginning of the study, there were no big differences in the number of overweight children
in the different groups. But by the end of the school year, children in the schools with water
fountains were 31 per cent less likely to gain extra pounds, compared to kids who went to other
schools, where water drinking was not encouraged.
      Children in the schools with fountains increased their water consumption from about 3 up to 4
glasses a day, while those in the other schools continued to drink an average of 3 glasses. Over
the research, the number of overweight kids upped from 384 to 385 out of 1,641 at the schools
with water fountains. In comparison, the number of overweight kids at the other schools increased
from 339 to 364 out of 1,309, Dr. Muckelbauer said.
      The experts cannot make any final conclusions and explain why the students who were encouraged
to drink water were less likely to gain extra weight. Dr. Muckelbauer noted that according to a few
other studies, drinking of water increases the rate at which calories are burned, while some other
research suggested that water may temporarily decrease appetite (食欲).

A. Drinking water certainly decreases appetite.
B. Further research is needed to support the finding.
C. The experts will encourage all the students to drink water.
D. Why students drinking more get less pounds will be clear soon.

4. What would be the best title for the passage?

A. Schools with water fountains

    1970 was World Conservation(自然保护)Year. The United Nations wanted everyone to know
that the world is in danger. They hoped that people would act quickly in order to conserve nature(大
自然). Here is one example of the problem. At one time there were 1,300 different plants, trees
and flowers in Holland, but now only 866 remain. The others have been destroyed by modern man.
It is said that there are tens of thousands of kinds of animals in the world, but now many have died
out(绝种). We are changing the earth, the air and water, and everything that grows and lives. We
can't live without these things. If we continue like this, we shall destroy ourselves.
    What will happen in the future?Perhaps it is more important to ask"What must we do now?"The
people who will be living in the world of tomorrow are the young of today. A lot of them know that
conservation is necessary. Many are helping to save our world. They plant trees, build bridges across
rivers and so on. In a small town in the United States a large group of girls cleaned the banks of 11
 kilometres of their river. Young people may hear about conservation through a record called"No
one's going to change our world."It was made by the Beatles, Cliff Richard and other singers. The
money from it will help to conserve wild animals.
