听力原文: During the Christmas shopping rush in London, the intriguing story was reported of a tramp who, apparently through no fault of his own, found himself locked in a well-known chain store late on Christmas Eve. No doubt the store was filled with last-minute Christmas shoppers and the staff were dead beating and longing to get home. Presumably all the proper security checks were made before the store was locked and they left to enjoy the three-day holiday untroubled by customers desperate to get last-minute Christmas presents.
However that may be, our tramp found himself alone in the store and decided to make the best of it. There was food, drink, bedding and camping equipment, of which he made good use. There must also have been television sets and radios. Though it was not reported if he took advantage of these facilities , when the shop re-opened, he was discovered in bed with a large number of empty bottles beside him. He seems to have been a man of good humour and philosophic temperament—as indeed vagrants very commonly are. Everyone else was enjoying Christmas, so he saw no good reason why he should not do the same. He submitted, cheerfully enough, to being taken away by the police. Perhaps he had a better Christmas than usual. He was put into prison for seven days. The judge awarded no compensation to the chain store for the food and drink our tramp had consumed. They had, in his opinion, already received valuable free publicity from the coverage the story received in the newspapers and on television. Perhaps the judge had a good Christmas too.
The tramp was locked in the store______
A.for his own mistakes
B.due to a misunderstanding
C.by accident
D.through an error of judgment

D.There is reason for caution but no cause for alarm with regard to food consumption.
Steps are being taken to preserve the black robin. Detailed studies are going on, and a public appeal for money has been made. The idea is to buy another island nearby as a special home for threatened wild life, including black robins. The organizers say that Little Mangere should then tie supplied with the robin’s food— it eats only one kind of seed. Thousands of the required plants are at present being cultivated in New Zealand. The public appeal is aimed at the conscience of mankind, so that the wild black robin will not die out and disappear from the earth in our lime at least.
Is all this concern a waste of human effort? Is it any business of ours whether the black robin survives or dies out? Are we losing our sense of what is reasonable and what is unreasonable?
In the earth’ s long, long past hundreds of kinds of creatures have evolved, risen to a degree of success—and died out. In the long, long future there will be many new and different forms of life. Those creatures that adapt themselves successfully to what the earth offers will survive for a long time. Those that fail to meet the challenges will disappear early. This is Nature’s proven method of operation.
The rule of selection—the survival of the fittest—is the one by which human beings have themselves arrived on the scene. He, being one of the most adaptable creatures the earth has yet produced, may last longer than most. You may take it as another rule that when, at last, man shows signs of dying out , no other creature will extend a paw to postpone our departure. For Nature, though fair, is a hard-hearted mistress. She has no favorites.
Life seems to have grown too tough for black robins. I leave you to judge whether we should try to do something about it.
The black robins are getting fewer and fewer because ______.
A.there are too many other kinds of birds on the island
B.of lack of food
C.they can’t multiply
D.there is no room for them on the island
