There is no creature that does not need sleep or complete rest every day.
If you want to know why, just try going without sleep for a long period of time. You will discover that your mind and body would become too tired to work properly. You would become irritable and find it hard to think clearly or concentrate on your work. So sleep is quite simply the time when the cells of your body recover from the work of the day and build up supplies of energy for the next period of activity.
One of the things we all know about sleep is that we are unconscious in sleep. We do not know what is going on around us. But that doesn't mean the body stops all activity. The important organs continue to work during sleep, but most of the body functions are slowed down.
For example, our breathing becomes slower and deeper. The heart beats more slowly, and the blood pressure is lower. Our arms and legs become limp(柔软的) and muscles are at rest. It would be impossible for our body to relax to such an extent if we were awake. So sleep does for us what the most quiet rest can not do.
Your body temperature becomes lower when you are asleep, which is the reason people go to sleep under some kind of covers. And even though you are unconscious, many of your reflexes(习惯性思维) still work. For instance, if someone tickles(使觉得痒) your foot, you will put it away in your sleep, or even brush a fly from your forehead. You do these things without knowing it.
If you don't have as much sleep as your body needs, you will ______.
A.work properly
B.think clearly
C.keep your attention on your work
D.easily get angry
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 a relatively short period of time, so we may assume 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. As time goes on, however, we shall have to use our brains more and more, and eventually we shall need larger ones. This is likely to bring about a physical change to the head, in particular the forehead, which 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 very 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, how ever, our fingers will grow more sensitive because they are used a great deal in modern life.
But what about hair? It will probably disappear from the body altogether in course of time because it does not serve a useful propose 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 emotions similar to our own.
The passage tells us about ______.
A.how man's life will be in the future
B.how future man will look like
C.the fact that man's organs will function differently in the future
D.the fact that man is growing uglier as time passes
Biologists today don’t expect that anyone will find a magical fountain of youth.Growing older is a natural part of the life cycle that can’t be reversed.As human beings grow older, organs such as the heart and lungs may stop functioning properly.Sight and hearing may become weak.And the human body becomes more likely to come down with serious illnesses from which it cannot recover.
Considered together, changes that bring about the decline of an organism are called aging.Because of aging, many biologists believe that there may be a maximum age limit to which even the healthiest organisms can live.For human beings, this maximum age limit is about 110 years.
Perhaps the most important thing that you can learn from your study of human biology is that you have a lot of control over the aging process in your own life.In fact, within our control are many physical and mental factors that have much to do with aging.For example, each of us, as recent research indicates, can do many things to help prevent heart and vessel disease, which causes half the death each year in the United States.We can avoid eating a lot of fatty meat.Eating too much of these types of animal fats can lead to the clogging and hardening of blood vessels.We can cut back on smoking and hopefully quit entirely.We can limit the amount of alcohol we drink and the amount of sugar we eat.We can exercise regularly and strengthen the heart and other organs.And we can remember to take time out each day for ourselves, time just relax.Exercise, recreation and relaxation all reduce stress – inner tension that is hard on all body organs.
One final thing we can do is to try to keep aware of advances made in health education.Information is often available free of charge from health clinics or schools.

Yet one saw, even before the 100th anniversary of the death of Queen Victoria this year, that there were signs these sneering attitudes were beginning to change. Programmes on radio and television about Victoria and the age that was named after her managed to humble themselves only about half the time. People were beginning to realize that there was something heroic about that epoch and, perhaps, to fear that the Victorian age was the last age of greatness for this country.
Now a new book, What The Victorians Did For Us, aims further to redress the balance and remind us that, in most essentials, our own age is really an extension of what the Victorians created. You can start with the list of Victorian inventions. They were great lovers of gadgets from the smallest domestic ones to new ways of propelling ships throughout the far-flung Empire. In medicine, anaesthesia (developed both here and in America) allowed surgeons much greater time in which to operate—and hence to work on the inner organs of the body—not to mention reducing the level of pain and fear of patients.
To the Victorians we also owe lawn tennis, a nationwide football association under the modern rules, powered funfair rides, and theatres offering mass entertainment. And, of course, the modern seaside is almost entirely a Victorian invention. There is, of course, a darker side to the Victorian period. Everyone knows about it mostly because the Victorians catalogued it themselves. Henry Mayhew’s wonderful set of volumes on the lives of the London poor, and official reports on prostitution, on the workhouses and on child labour—reports and their statistics that were used by Marx when he wrote Das Kapital—testify to the social conscience that was at the center of “Victorian values”.
But now, surely, we can appreciate the Victorian achievement for what it was—the creation of the modern world. And when we compare the age of Tennyson and Darwin, of John Henry Newman and Carlyle, with our own, the only sensible reaction is one of humility: “We are our father’s shadows cast at noon”.
第16题:According to the author, Lytton Strachey’s book Eminent Victorians _____.
[A] accurately described the qualities of the people of the age
[B] superficially praised the heroic deeds of the Victorians
[C] was highly critical of the contemporary people and institutions

A.surely become a musician
B.mostly become a poet
C.possibly become a doctor
D.become a musician on the condition that all these factors are organized around music
In our discussion of instincts we saw that there was reason to believe that whatever we inherit must be of some very simple sort rather than any complicated or very definite kind of behavior. It is certain that no one inherits a knowledge of mathematics. It may be, however, that children inherit more or less of a rather general ability that we may call intelligence. If very intelligent children become deeply interested in mathematics, they will probably make a success of that study.
As for musical ability, it may be that what is inherited is an especially sensitive ear, a peculiar structure of the hands or the vocal organs connections between nerves and muscles that make it comparatively easy to learn the movements a musician must execute, and particularly vigorous emotions. If these factors are all organized around music, the child may become a musician. The same factors, in other circumstances might be organized about some other center of interest. The rich emotional equipment might find expression in poetry. The capable fingers might develop skill in surgery. It is not the knowledge of music that is inherited then, nor even the love of it, but a certain bodily structure that makes it comparatively easy to acquire musical knowledge and skill. Whether that ability shall be directed toward music or some other undertaking may be decided entirely by forces in the environment in which a child grows up.
