  The National Gallery of Art in Washington,D.C., is one of the world's greatest art museums.Millions of people have entered its doors to see paintings by the world's fine artists.But if these priceless masterpieces are to be preserved, the Gallery must protect them carefully.The Gallery's 135-man guard force has successfully prevented them from being stolen, but protecting the paintings from nature is a greater problem.

  In past times, the owners of paintings did not protect them from damaging changes in humidity(湿度)and temperature.As a result, the life of these paintings were shortened.In the National Gallery, however, humidity and temperature are carefully controlled.The building is air-conditioned in summer and heated in winter.The air-conditioning and heating system are so important to the life of the painting that the Gallery has two of each system.If one should fail, the extra one can take over.

  Light is another enemy of paintings.Ultraviolet rays(紫外线)in light cause paintings to fade(褪色).Long ago, paintings often hung in dark churches and palaces.A coat of varnish(清漆)was a protection from the weak light.But when museums took over the care of many paintings, they were often hung in brighter light than before.Soon they were in danger of fading.The damaging effects of light were increased when the museums removed the varnish coating, yellowed with age.

  To protect its paintings, the National Gallery put a special kind of glass in its skylights.This glass allows visible lights to enter the building but it keeps out harmful ultraviolet rays.The Gallery has also developed new and better varnishes which help to keep paintings from fading.

  Thanks to these new precautions, many of the world's greatest paintings are being well protected for future generations to enjoy.

                                   A

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.
