Cats are creatures of habit.They like to go to sleep about the same time every day and for a certain length of time.They seem to have a natural clock inside them that tells them when to sleep.
Cats increase their regular sleep with occasional cat naps(打盹).Some experts feel that humans could also benefit from this habit.Cat naps help to build up energy in the body.They are also a good way to get rid of trouble!Since cats have the same moods(情绪)as humans,some experts behave that people can improve their moods.People might become happier.
A number of famous people have copied cats by taking cat naps during the day.The naps would usually last from 15 to 30 minutes.
Winston Churchill took cat naps.So did Presidents Harry Truman,John F.Kennedy and Lyndon B.Johnson.These famous men were known for their energy.They were also able to work long hours,often into the night.Napping was their secret.

第2题:

Suppose we built a robot(机器人)to explore the planet Mars. We provide the robot with seeing detectors(探测器)to keep it away from danger. It is powered entirely by the sun. Should we program the robot to be equally active at all times? No. The robot would be using up energy at a time when it was not receiving any. So we would probably program it to stop its activity at night and to wake up at dawn the next morning.

According to the evolutionary(进化的)theory of sleep, evolution equipped us with a regular pattern of sleeping and waking for the same reason. The theory does not deny(否认)that sleep provides some important restorative functions(恢复功能). It merely says that evolution has programmed us to perform. those functions at a time when activity would be inefficient and possibly dangerous. However, sleep protects us only from the sort of trouble we might walk into;it does not protect us form. trouble that comes looking for us. So we sleep well when we are in a familiar, safe place, but we sleep lightly, if at all, when we fear that bears will nose into the tent.

The evolutionary theory explains the differences in sleep among creatures. Why do cats, for instance, sleep so much, while horses sleep so little? Surely cats do not need five times as much repair and restoration as horses do. But cats can afford to have long periods of inactivity because they spend little time eating and are unlikely to be attacked while they sleep. Horses must spend almost all their waking hours eating, because what they eat is very low in energy value. Moreover, they cannot afford to sleep too long or too deeply, because their survival(生存)depends on their ability to run away from attackers.

1. The author uses the example of the robot in space exploration to tell us _____.

A. the differences between robots and men

B. the reason why men need to sleep

C. about the need for robots to save power

D. about the danger of men working at night

2. Evolution has programmed man to sleep at night chiefly to help him _____.

A. keep up a regular pattern of life

B. prevent trouble that comes looking for him

C. avoid danger and inefficient labour

D. restore his bodily functions

3. According to the author, we cannot sleep well when we _____.

A. are worrying about our safety

B. are overworked

C. are in a tent

D. are away from home

4. Cats sleep much more than horses do partly because cats _____.

A. need more time for restoration

B. are unlikely to be attackers

C. are more alive than horses when they are awake

D. spend less time eating to get enough energy

5. Which of the following is the main idea of the passage? _____

A. Evolution has equipped all creatures with a regular pattern of sleeping and waking.

B. The study of sleep is an important part of the evolutionary theory.

C. Sleeping patterns must be taken into consideration in the designing of robots.

D. The sleeping pattern of a living creature is determined by the food it eats.

Passage 1
Plants and animals that have been studied carefully seem to have built-in clocks. These biological clocks, as they are called, usually are not quite exact in measuring time. However, they work pretty well because they are "reset" each day, when the sun comes up.
Do pigeons use their biological clocks to help them find directions from the sun? We can keep pigeons in a room lit only by lamps. And we can program the lighting to produce artificial "days",different from the day outside. After a while we have shifted their clocks. Now we take them far away from home and let them go on a sunny day. Most of thegn start out as if they know just which way to go, but choose a wrong direction. They have picked a direction that would be correct for the position of the sun and the time of day according to their shifted clocks.
It is known and experimented that homing pigeons can tell directions by the sun. But what happens when the sky is darkly overcast by clouds and no one can see where the sun is? Then the pigeons still find their way home. The salne experiment has been repeated many times on sunny days and the result was always the same. But on very overcast days clock-shifted pigeons are just as good as normal pigeons in starting out in the right directions. So it seems that pigeons also have some extra sense of direction to use when they cannot see the sun.
Naturally, people have wondered whether pigeons might have a built-in compass—something that would tell them about the directions of the earth's magnetic field. One way to test that idea would be to see if a pigeon's sense of direction can be fooled by a magnet attached to its back.
With a strong magnet close by, a compass can no longer tell direction.
To test the idea, a group of ten pigeons had strong little magnet bars attached to their backs.
Another group carried brass bars instead which were not magnetic. In a number of experiments,both groups were taken away from home and let go. On sunny days none of the magnet-pigeons was fooled. They were just as good as the brass-pigeons in starting out in the right direction toward home. On cloudy, overcast days, however, with no sun the brass-pigeons chose the right direction,but the magnet-pigeons were in trouble. They later started out in different directions and acted completely lost.

What can be inferred from the passage about biological clocks?

A.They are used by all plants and animals to tell time.

Passage One

Animals have different ways of protecting themselves against wintertime weather. Some animals grow heavy coats of fur or feathers, while others dig into the ground to find a warm wintertime home.

Some animals spend the winter in a deep sleep because by going to sleep they avoid the time of the year when food is scarce and the temperatures are low. Their sleep is known as hibernation.

There is much about hibernation that puzzles scientists. For example, they are wondering how hibernation came into being. Some scientists have explored the possibility that animals release a chemical that starts them hibernating.

One thing that scientists are certain about is that animals hibernate only when it is cold. Hibernation is a seasonal practice.

Some animals that fall into a wintertime sleep are not true hibernators because they spend only a part of the cold season asleep. Bears, for example, can easily be awakened from their winter nap. They are not true hibernators.

Sometimes it is difficult to determine whether a particular animal is a true hibernator. For example, some mice hibernate, but others do not. The same is true of bats. Some of them hibernate. Others do not.

36. Hibernation is a seasonal practice. This means it ______.

A. takes place only during a particular season

B. occurs only during the night

C. is a daily practice

D. only happens when a species becomes over-populated

Sunday is more like Monday than it used to be, Places of business that used to keep daytime “business hours” are now open late into the night. And on the Internet, the hour of the day and the day of the week have become irrelevant (不相关的).A half century ago in the United States, most people experienced strong and precise dividing lines between days of rest and days of work, school time and summer time. Today the boundaries still exist, but they seem not clear.

The law in almost all states used to require stores to close on Sunday; in most, it no longer does, It used to keep the schools open in all seasons except summer, in most, it still does. And whether the work week should strengthen its legal limits, or whether it should become more “flexible,” is often debated. How should we, as a society, organize our time? Should we go even further in relaxing the boundaries of time until we live in a world in which every minute is much like every other?

These are not easy questions even to ask. Part of the difficulty is that we rarely recognize the “law of time” even when we meet it face to face. We know as children that we have to attend school a certain number of hours, a certain number of days, a certain number of years – but unless we meet the truant officer (学监) ,we may well think that we should go to school due to social custom and parents’ demand rather than to the law. As adults we are familiar with “extra pay for overtime working,” but less familiar with the fact that what constitutes(构成) “overtime” is a matter of legal definition. When we turn the clock forward to start daylight – saving time, have we ever thought to ourselves: “Here is the law in action”? As we shall see, there is a lot of law that has great influence on how organize and use time: compulsory education law, overtime law, and daylight – saving law- as well as law about Sunday closing, holidays, being late to work, time zones, and so on. Once we begin to look for it, we will have no trouble finding a law of time to examine and assess.

67. By saying” Sunday is more like Monday than it used to be,” the writer means that __________.

A. work time is equal to rest time

B. many people have a day off on Monday,

C. it is hard for people to decide when to rest

D. the line between work time and rest time is unclear

Australia has a lot of lovely animals. You cannot find them anywhere else in the world. The most famous ones are kangaroos(袋鼠)and koalas(树袋熊).

The kangaroo is the symbol of Australia. They have large eyes and ears. They don’t walk, they jump. They use their strong back legs. They can jump at 74 kilometres per hour. They can go over nine metres in one jump.Kangaroo mothers have pouches to carry their babies. The babies stay inside to get milk and keep warm.

Kangaroos are everywhere in Australia. They are on TV, in books and in the shops. But do you know that millions of kangaroos are killed every year ? There are too many of them.There are about 20 to 25 million kangaroos in Australia. That’s more than the number of people in the country.Some kangaroos go hungry because there is not enough food to eat. They break into farms for food. Farmers are very angry with them.

The koala is another famous Australian animal. They look like bears, and have small eyes and big noses. They eat leaves from gum trees(桉树).Koalas have a special smell. They use it to mark their home—“ This is my place, you can’t come in !” Like kangaroos, a koala baby lives in its mother’s pouch, too.

66. If we want to see kangaroos and koalas in natural forests, we can go to ________ .

A. China B. France C. Australia
