    阅读下列短文，从每题所给的四个选项A、B、C和D中，选出最佳选项。

    　　With the development of science and technology, the research of human genes is playing more and more important part in our daily life．Sometimes it is a hot topic drawing more and more attention．

    　　Gene technology can cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease．Every year, millions of people are murdered by these two killers．But if the gene technology is used, not only these two diseases can be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend curing their diseases can be saved, therefore it benefits the economy as well．In addition, people can live longer．

    　　Gene technology can help people to give birth to more healthy and clever children．Some families have hereditary diseases and their children will for sure have the family disease, which is a great trouble for these families．In the past, doctors could do nothing about them．But gene technology can solve this problem perfectly．The scientists just need to find the wrong gene and correct it, and a healthy child will be born．

    　　Some people are worrying that the gene research can be used to clone human beings in large quantities．In the past few years, scientists have succeeded in cloning a sheep; therefore these people predict that human babies would be cloned．But I believe cloned babies will not come out in large amounts, for most couples in the world can have babies in a very normal way．Of course, the governments must take care to control gene technology．

    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（短吻鳄） 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 (拔河比赛) 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 (留下伤疤) 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 （外伤）, 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 （认同） 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.
