閱讀理解:閱讀下列短文, 從所給的四個選項中, 選出最佳答案。 

    Animals seem to have the sense to eat when they are hungry and　　 they do not eat more than their bodies need. It has been demonstrated　　 (證實) that rats will, when given a choice over a period of time,　　 prefer water with vitamins (維生素) to water without vitamins, even　　 though there is no difference in taste or smell between the two water　　 bottles. When a fragrant flavor (香味) was added to the　　 vitamin—enriched liquid, the rats did seem to develop a taste for it　　 and kept drinking it, even after the vitamins were switched (轉(zhuǎn)) to　　 the clear water. In time, however, they broke the habit and went back　　 to where the necessary vitamins were.

　　

　　    In an experiment, babies of 6 to 12 months old were placed in a　　 cafeteria (自助食堂) with a wide selection of baby food before them.　　 They were given whatever food they pointed to or appeared interested　　 in. We are told that at first they showed some unusual eating　　 patterns, but over a period of time they managed to select a well　　 balanced diet (飲食).

　　

　　     So, in selecting food, rats and babies do seem to know and act on　　 what's best for them. Clearly, there is a kind of "body wisdom" which　　 humans soon lose. Most of us do not eat as wisely as we could. Many　　 of our food preferences are culturally determined and influenced (影　　 響) by long-established habits. Some people eat fox, dog and　　 blackbirds, while we eat cows and pigs. So what people eat and how　　 much they eat seems to be greatly influenced by what is going on　　 around them.　　

　　

(1)In the experiment on rats, a fragrant flavor was added to the　　 rat's drinking water to ________.

[　　]

A. encourage rats to drink it　　 　　

B. find out what kind of flavor rats prefer　　 　　

C. test whether rats know which drink is with fragrant flavor　　 　　

D. demonstrate that vitamins are tasteless　　 　　

(2)The expression "the habit" in the first paragraph refers to　　 drinking water which __________.　　　　　　　　　　

[　　]

A. has no smell　　 B. is tasteless

C. has vitamins　　 D. is flavored　　 　　

(3)As far as their eating habits are concerned, babies and rats　　 are similar (相似) because ___________.　　　　　　

　　

[　　]

A. both have the wisdom to choose a balanced diet　　 　　

B. both prefer flavored food and drink　　 　　

C. both have the same eating patterns　　 　　

D. both develop a taste for the same kinds of flavors　　 　　

(4)In the experiment mentioned in the second paragraph, babies　　 were _________.

A. given many choices of drinks　　 　　

B. provided with various kinds of baby food　　 　　

C. placed and fed in a cafeteria　　 　　

D. trained to select a balanced diet　　 　　

(5)According to the passage, adults' (成年人) eating habits differ　　 from those of babies because ____________.　　　　

　　

[　　]

A. adults know better than babies what kinds of food are good for their health　　 　　

B. adults usually cannot resist the temptation of various delicious foods　　 　　

C. adults' eating habits are closely related to the social and cultural customs　　 　　

D. adults have more choices of food than babies in eating patterns

Scars of Love

Some years ago on a hot summer day in south Florida a little boy decided to go for a swim in the old swimming hole behind his house. In a hurry to dive into the cool water, he ran out of the back door, leaving behind shoes, socks and shirt as he went.

He flew into the water, not realizing that as he swam toward the middle of the lake, an alligator（短吻鱷） was getting close. The mother in the house was looking out of the window and saw the two as they got closer and closer together. In great fear, she ran toward the water, yelling to her son as loudly as she could. Hearing her voice, the little boy became alarmed and made a U-turn to swim to his mother. It was too late. Just as he reached her, the alligator reached him. From the dock, the mother grabbed her little boy by the arms just as the alligator snatched (抓住) his legs. That began an unbelievable tug-of-war (拔河比賽) between the two. The alligator was much stronger than the mother, but the mother was much too passionate to let go. A farmer happened to drive by, heard their screams, rushed from his truck, took aim and shot the alligator.

Remarkably, after weeks and weeks in the hospital, the little boy survived. His legs were extremely scarred (留下傷疤) by the terrible attack of the animal. And on his arms, were deep scratches where his mother’s fingernails dug into his flesh in her effort to hang on to the son she loved.

The newspaper reporter, who interviewed the boy after the trauma （外傷）, asked if he would show him his scars. The boy lifted the pant legs. And then, with obvious pride, he said to the reporter, “Look at my arms. I have great scars on my arms, too. I have them because my mum wouldn’t let go.”

You and I can identify with （認同） that little boy. We have scars, too. Not from an alligator, but the scars of a painful past. Some of those scars are unsightly and have caused us deep regret. But, some wounds, my friends, are because we have refused to let go.

56. The underlined part “the two” in the second paragraph refers to ______.

   A. the alligator and the mother         B. the mother and the son

C. the driver and the alligator          D. the son and the alligator

57. From the passage we can infer ________.

   A. The mother was unwilling to let the alligator go

   B. The mother was actually stronger than the alligator

   C. The son was proud of his scars on his arms

   D. The son was ashamed of his scars on his legs

58. According to the last paragraph, what is the writer’s real meaning?

   A. To forget the past is to betray.       B. We should forget the scars.

   C. Wounds are different from scars.     D. We should learn to let go sometimes.
