    阅读理解，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。

    　　Batteries are included, but the charger's not．The Nokia E-Cu concept phone doesn't need to plug in, it charges from any heat source．Designer Patrick Hyland says it can even work off the warmth of your pocket．The first time “it would take approximately seven hours to reach full charge, then after that it's continuously charging by keeping the phone in areas between 86 degrees and 104 degrees Fahrenheit．” That's one hot pocket．?

    　　He's put a thermogenerator(热偶电池)inside the phone that transforms heat into electric potential energy．To better conduct the heat to that little power plant in your pocket, the E-Cu(E for energy, Cu for copper)is coated by copper backing with heat sinks like those normally used to keep electronics from overheating．

    　　Nokia doesn't have current plans to build the phone, so for now it remains a concept．But Hyland says he's open to anyone who wants to cooperate．

    　　For Americans this technology would certainly be convenient．It would also save a bit on energy bills and waste．“Annually, unwanted phone chargers produce 51, 000 tons of waste in addition to the greenhouse gases created by the production of the electricity needed to charge them, ” Hyland says．So a charger-free phone is also a green phone．Though adapting our plug?in habits would help a group of people, most cell phone related energy use comes from leaving your charger plugged in all day unnecessarily．

    　　The real potential for charger-free cell phone technology is what it could enable places where plugging in isn't an option, like rural areas in the developing world．

    　　Cell phones are spreading faster than power lines and bringing with them countless opportunities, aid and health advances．A phone like the E-Cu, if it ever comes to be, would enable all manner of expanded aid and development by phone projects．Let's hope Patrick finds a partner．

    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.
