For many people today, reading is no longer relaxation. To keep up their work

they must read letters, reports, trade publications, interoffice communications, not to mention newspapers and magazines: a never-ending flood of words. In _51__ a job or advancing in one, the ability to read and comprehend _52__ can mean the difference between success and failure. Yet the unfortunate fact is that most of us are __53_ readers. Most of us develop poor reading _54__ at an early age, and never get over them. The main deficiency _55__ in the actual stuff of language itself-words. Taken individually, words have _56__ meaning until they are strung together into phrases, sentences and paragraphs. _57__, however, the untrained reader does not read group of words. He laboriously reads one word at a time, often regressing to _58__ words or passages. Regression, the tendency to look back over _59__ you have just read, is a common bad habit in reading. Another habit which _60__ down the speed of reading is vocalization--- sounding each word either orally or mentally as _61__ reads. To overcome these bad habits, some reading clinics use a device called an _62__, which moves a bar (or curtain) down the page at a predetermined speed. The bar is set at a slightly faster rate _63__ the reader finds comfortable, in order to “stretch” him. The accelerator forces the reader to read fast, _64__ word-by-word reading, regression and subvocalization, practically impossible. At first _65__ is

sacrificed for speed. But when you learn to read ideas and concepts, you will not only read faster, _66__ your comprehension will improve. Many people have found _67__ reading skill drastically improved after some training. _68__ Charlce Au, a business manager, for instance, his reading rate was a reasonable good 172 words a minute _69__ the training, now it is an excellent 1,378 words a minute. He is delighted that now he can _70__ a lot more reading material in a short period of time.

There are four reading passages in this part. Each passage is followed by five question, for each question there are four suggested answers marked A, B, C and D. Choose the best answer and blacken the corresponding letter on ANSWER SHEET.

Passage 1

Suppose we built a robot (机器人) to explore the planet Mars. We provide the robot with seeing detectors 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 cease 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. 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 from trouble that comes looking for us. So we sleep well when we are in familiar, safe place, but we sleep lightly, if at all, when we fear that bears will nose into the tent.

The evolutionary theory accounts well for 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 depends on their ability to run away from attackers.

31. 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

32. Evolution has programmed man to sleep at night chiefly to help him ______. A) maintain a regular pattern of life

B) prevent trouble that comes looking for him C) avoid danger and inefficient labor D) restore his bodily functions

33. 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

34. 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 active than horses when they are awake D) spend less time eating to get enough energy

35. 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 2

The physicians in a hospital form the core of the medical staff. But they could not provide effective medical care to their patients without the help of numerous other medical employees. From the viewpoint of the patients, the nursing staff is

particularly important. Nurses are usually in close contact with patients as long as they are in the hospital.

A nurse does not study for as many years as a doctor, however, each must be equally dedicated. Caring for sick persons requires a great deal of patience and concern. Most nurses work long days, and they often must work at odd hours or during the night.

Under the supervision of the head nurse, the nursing staff must provide nursing services on a 24-hour basis and attend to patients’ needs. This responsibility continues around the clock, and so nurses must work in shifts. A shift is a period of duty,
