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

All whales fall into two groups, those with teeth and those without. Both beluga and dolph

in belong to the suborder of toothed whales known as Odontoceti, along with porpoises, narwhals, pilot whales, killer whales and the largest toothed creature in the world, the sperm whale. Size differences among the Odontoceti are remarkable. A common porpoise will run only 4 or 5 feet in length and 300 pounds in weight; a sperm whale may be 10 times as long and 300 times as heavy. The beluga falls in between, weighing up to 2,000 pounds. And it does chirp. In fact, it makes a great variety of squeaking, whistling, and clicking sounds, which have earned it the name of sea canary.

The toothless, or baleen, whales belong to the suborder of Mysticeti. This is a group of generally large whales, formerly abundant in all the oceans of the world. Though reduced by hunting, most species are still found along the coasts of the United Stated and Canada. All but two of the Mysticeti reach 40 feet or more at maturity, with the blue whale running up to 100 feet and tipping the scales at up to 130 tons. This whale is by far the largest creature that has ever lived on earth, 4 times the weight of the largest dinosaur, 30 times that of an elephant.

With what topic is the passage mainly concerned？

A．Breeding habits of whales.

B．Differences between whales.

C．Efforts to preserve whales.

D．The intelligence of whales.

第7题

We spend our leisure hours efficiently for higher production, live by the clock even when

time does not matter, modernize our homes and speed the machinery of living in order that we can go to the most places and do the most things in the shortest period of time possible. We try to eat, sleep, and talk efficiently. Even on holidays and Sundays, the efficient man relaxes on timetable with one eye on the clock and the other on an appointment sheet.

To squeeze the most out of each shining hour we have shortened the opera, quickened the pace of the movie and put culture in pocket-sized packages. We make the busy bee look like a lazy creature, the ant like a sluggard. We live sixty-mile-minute and the great efficiency smiles.

We wish we could return to that pleasant day when we considered time a friend instead of an enemy; when we did things willingly and because we wanted to, rather than because our timetable called for it, But that of course would not be efficiency; and we Americans must be efficient.

The phrase that best expresses the main idea of this passage is ______. ()

A．the modern pace

B．our interest in shortened operas

C．how to make the best use of leisure time

D．planning our time scientifically

根据以下内容回答题：Let US take a look at the chief thing in the story—the human body itsel

根据以下内容回答题：

Let US take a look at the chief thing in the story—the human body itself．A human body appears to be rather soft and delicate，compared with that of a wild animal，but it is actually surprisingly strong．Indeed，its very softness and looseness are an advantage；it makes man good at moving about and falling about in safety．Man is the most skillful in movement of all living things of his own size，because he can do so many different things with his limbs．Man’s games show how he can control his own body．No other land creature can swim as skillfully as man；none has such varied grace；very few live as long as he；none is so strong in its natural resistance to disease．Therefore man has a great advantage in his battle against the risks of damage and death that threaten him．It is difficult to kill him as long as he is fed and in good health．Yet every day thousands of people die needlessly，even though man is naturally strong，because of those two killers，disease and starvation，with the battle．

Old age？No one can live forever，so one might’suppose that quite a large number of oldpeople would come to the end of their days every year．There is，however，another thing to re-member．During the time it has taken you to read this page，a considerable number of babies have been born somewhere in the wodd—one is born every one and a quarter seconds!Of these babies，one group can be expected to have a good long life of about seventy years，because they were lucky enough to be born in countries where living standards are high．

The deadliest of all killers are starvation and disease．We cannot be content until we have mastered them．To do so is one of the most important tasks of our times．

The softness and looseness of man’s body are an advantage because it__________ ．查看材料

A.makes him strong

B.makes him resistant to diseases

C.helps him to avoid injury

D.keeps him in good health
