Sleep is important to us because it helps restore organs and tissues in our body. But how much sleep do we actually need？

For most of us, eight hours seems to be about the right amount. Yet we know that there are many people who get 【61】 perfectly with less sleep, and some who may need 【62】 A great deal depends on the 【63】 we live. But a good general rule 【64】 is to sleep as long as we have to in order to feel happy and be able to work 【65】 our best when we awaken.

There are actually different 【66】 of sleep. There is a deep sleep and a shallow sleep. In a shallow sleep our body does not get the same kind of rest it gets in a 【67】 sleep, 【68】 after eight hours of a shallow sleep we may still feel tired. But a short, deep sleep can be very 【69】 Alexander—the Great Emperor was able to get a deep sleep 【70】 he needed it. Once, during the night before an important battle, he remained 【71】 longer than anyone else. 【72】 he wrapped himself in a cloak and 【73】 down on the earth. He slept so 【74】 that his generals had to wake him three times for him to give the 【75】 to attack!

Normally when we go to sleep, our " sleep center" blocks off nerves so that 【76】 our brain and body go to sleep. 【77】 prevents us from wanting to do anything, and the other 【78】 our internal organs and limbs go to sleep. 【79】 sometimes only one goes to sleep and the other does not. A very tired soldier can sometimes 【80】 asleep (brain sleep) and keep on marching, because his body is not asleep.

To us it seems so natural to put up an umbrella to keep the water off when it rains. But a

ctually the umbrella was not invented as protection against rain. Its first use was as a shade against the sun!

Nobody knows who first invented it, but the umbrella was used in very ancient times. Probably the first to use it were the Chinese, as early as the eleventh century B. C.

We know that the umbrella was used in ancient Egypt and Babylon as a sunshade. And there was a strange thing connected with its use: it became a symbol of honour and authority. In the Far East in ancient times the umbrella was allowed to be used only by royalty or by those in high office.

In Europe, the Greeks were the first to use the umbrella as a sunshade. And the umbrella was in common use in ancient Greece. But it is believed that the first persons in Europe to use the umbrella as protection against the rain were the ancient Romans.

During the Middle Ages, the use of the umbrella practically disappeared. Then it appeared a gain in Italy in the late sixteenth century. And again it was considered a symbol of power and authority. By 1680, the umbrella appeared in France, and later on in England.

By the eighteenth century, the umbrella was used against rain throughout most of Europe. Umbrellas have not changed much in style. during all this time, though they have become much lighter in weight. It wasn' t until the twentieth century that women' s umbrellas began to be made, in a whole variety of colours.

According to this passage, the umbrella was probably first invented ______.

A．in ancient China

B．in ancient Egypt

C．in ancient Greece

Everyone seems to be in favor of progress. But " progress" is a funny word. It doesn't nec

essarily mean that something has become stronger, wiser, or better. It simply means changing it from being one thing to another and sometimes it turns out to be worse than before.

Consider medicine, for instance. No one can deny that medical progress has enriched our lives tremendously. Because of medical advances, we eat better, live easier and are able to take care of ourselves more efficiently. We can cure disease with no more than one injection or a pill. If we have a serious accident, surgeons can put us back together again. If we are born with something defective, they can repair it. They can make us happy, restore our normality, ease our pain, replace worn parts and give us children. They can even bring us back from the dead. These are wonderful achievements, but there is a price we have to pay.

Because medicine has reduced infant mortality and natural death so significantly, the population has been rising steadily, in spite of serious efforts to reduce the rate of population growth. Less than a century ago in the United Stales, infant mortality claimed more than half of the newborn within the first year of life. Medical advances, however, have now reduced that rate to nearly zero. A child born in the United States today has better than a 90% chance of survival. Furthermore, medical advances have ensured that most of these infants will live to be seventy years of age or more, and even that life expectancy increases every year. The result of this progress is an enormous population increase that threatens the quality of life, brought about by progress in the medical profession.

According to this passage, " progress" doesn't always mean that______.

A．something has become stronger and better

B．something has been changed from being one thing to another

C．something has become funny

D．something turns out to be worse than before

完成下列各题 B Light travels at a speed which is about a million

times faster than the speed of sound．In one second，light travels about 300，000km．But sound travels only 344m．You can get some idea of this difference by watching the start of a race．If you stand some distance away from the starter，you can see smoke comes from his gun before the sound reaches your ears． This great speed of light gives US some strange facts．Sunlight takes about 8 minutes to reach US．If you look at the light of the moon tonight，remember that the light left the moon 1．3 seconds before it reached you．The nearest star is so far away that the light which you can see from it t0—night started to travel towards you four years ago at a speed of nearly 2 million km per minute．In some case，the light from one of tonight’s stars started on its journey to you before you were born． Thus，if you want to be honest，you cant say“The stars are shining to night”？You have to say“The stars look pretty．They were shining four years ago but their light has just reached Earth”． Sunlight seems to________than the light of the moon．

A.be less powerfull

B.travel much quickly

C.move less quickly
