[主观题]

Although each baby has an individual schedule of development, general patterns of growth h

ave been observed. Three periods of development have been identified (确定) , including early infancy (幼儿期) , which extends from the first to the sixth month; middle infancy, from the sixth to the ninth month; and late infancy, from the ninth to the fifteenth month. Whereas the newborn is concerned with his or her inner world and reacts primarily to hunger and pain in early infancy, the baby is already aware of the surrounding world. During the second month, many infants are awake more and can raise their heads to look at things. They also begin to smile at people. By four months, the baby is searching for things but not yet grasping them with its hands. It is also beginning to be wary(谨慎的) of strangers and may scream when a visiting relative tries to pick it up. By five months, the baby is grabbing objects and putting them into its mouth. Some babies are trying to feed themselves with their hands.

In middle infancy, the baby concentrates on practicing a great many speech sounds. It loves to imitate actions and examine interesting objects. At about seven months, it begins to crawl, a skill that it masters at the end of middle infancy.

In late infancy, the baby takes an interest in games, songs, and even books. Progress toward walking moves through standing, balancing, bouncing in place, and walking with others. As soon as the baby walks well alone, it has passed from infancy into the active toddler (蹒跚学步) stage.

What is the main subject of this reading passage？

A．Growth in early infancy.

B．The active toddler.

C．How a baby learns to walk.

D．The developmental stages of infancy.

For some time past it has been widelyaccepted that babies-and other creatures-learn to do

For some time past it has been widely accepted that babies-and other creatures-learn to do things because certain acts lead to “rewards”; and there is no reason to doubt that this is true. But it used also to be widely believed that effective rewards, at least in the early stages, had to be directly related to such basic physiological (生理的)“drives” as thirst or hunger. In other words, a baby would learn if he got food or drink or some sort of physical comfort, not otherwise.

It is now clear that this is not so. Babies will learn to behave in ways that produce results in the world with no reward except the successful outcome.

Papousek began his studies by using milk in the normal way to“reward” the babies and so taught them to carry out some simple movements, such as turning the head to one side or the other. Then he noticed that a baby who had had enough to drink would refuse the milk but would still go on making the learned response with clear signs of pleasure. So he began to study the children's responses in situations where no milk was provided. He quickly found that children as young as four months would learn to turn their heads to right or left if the movement“switched on” a display of lights-and indeed that they were capable of learning quite complex turns to bring about this result, for instance, two left or two right, or even to make as many as three turns to one side.

Papousek's light display was placed directly in front of the babies and he made the interesting observation that sometimes they would not turn back to watch the lights closely although they would“smile and bubble” when the display came on. Papousek concluded that it was not primarily the sight of the lights which pleased them, it was the success they were achieving in solving the problem, in mastering the skill, and that there exists a fundamental human urge to make sense of the world and bring it under intentional control.

According to the author, babies learn to do things which______.

A．are directly related to pleasure

B．will meet their physical needs

C．will bring them a feeling of success

D．will satisfy their curiosity

第5题

After a day of work and play, the body needs to rest. Sleep is necessary for good health.

During this time, the body recovers from the activities of the previous day. The rest that you get while sleeping enables your body to prepare itself for the next day.

There are four levels of sleep, each being a little deeper than the one before. As you sleep, your muscles relax little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts back and forth from one level of sleep to another. Although your mind slows down, from time to time you will dream. Scientists who study sleep state that when dreaming occurs, your eyeballs begin to move quickly (although your eye-lids are closed). This stage of sleep is called REM, which stands for rapid eye movement.

If you have trouble falling asleep, some people recommend breathing very slowly and very deeply. Other people believe that drinking warm milk will help make you drowsy. There is also an old suggestion that counting sheep will put you to sleep.

A good title for this passage is______.

A．Sleep

B．Good Health

C．Dreams

D．Work and Rest

Directions: There are five reading passages in this part. Each passage is followed by five

questions. For each question there are four suggested answers marked A, B, C and D. Choose the best answer and blackening the corresponding letter on the answer sheet.

Passage One

Artificial flowers are used for scientific as well as for decorative purposes. They are made from a variety of materials, such as wax and glass, so skillfully that they can scarcely be distinguished from natural flowers. In making such models, painstaking skill and artistry are called for, as well as thorough knowledge of plant structure. The collection of glass flowers in the Botanical Museum of Harvard University is the most famous in North America and is widely known throughout the scientific world. In all, there are several thousand models in colored glass, the work of two artists-naturalists, Leopold Blaschka and his son Rudolph.

The intention was to have the collection represent at least one member of each flower family native to the United States. Although it was never completed, it contains more than seven hundred species representing 164 families of flowering plants, a group of fruits showing the effect of fungus diseases, and thousands of flower parts and magnified details. Every detail of these is accurately reproduced in color and structure. The models ate kept in locked cases, as they are too valuable and fragile for classroom use.

31. Which of the following is the best title for the passage？

A. An Extensive Collection of Glass Flowers.

B. The Live Leopold and Rudolph Blaschka.

C. Flowers Native to the United States.

D. Materials Used for Artificial Flowers.

第10题

There are many reasons of the tidal action which is a very complicated phenomenon involvin

g many factors all of which must be considered to predict tide in any one place at any one time. The alternate rise and fall of the surface of the seas and the ocean is mainly caused by the attractive force of the moon alone. When the attraction is great, the tide is high; and conversely when the attraction is minimal, the tide is low. Between the high and the low tide is a period of a little over six hours, being called during its rise a flood tide, and during its fall an ebb tide.

The sun also exerts its effect on the tide, being a lit fie less than half as much as the moon, although its mass is so much greater. When the moon and the sun are horizontal, the highest high tide occurs and when they are vertical the lowest low tide takes place.

The wind also plays an important part in the modification of the normal rise and fall of the tide. Thus these factors affect each other, either detracting or adding to the attractive forces to add or subtract from the weight of the tide. But the tides still move inexorably on, rising twice a day, getting a little later each day and posing a problem of correctly predicting their heights and lows.

Which of the following factors will not affect the time of the tide？

A．The position of the sun and the moon.

B．The mass of the moon.

C．The wind.

D．All of the above mentioned factors.
