单选题Most of the animals have little connection with animals of a different kind, unless they hunt them for food. Sometimes ,however, two kinds of animals come together in a partnership (伙伴关系) which is good for both of them. You may see some birds sitting on the backs of sheep. This is not because they want a ride ,but because they find easy food in the parasites (寄生虫)on sheep. The sheep allow the birds to do so because they move the cause of discomfort. So although they can live without each other, they do better together.
Sometimes an animal has a plant partner. The relationship develops until the two partners cannot live without each other. This is so in the corals (珊瑚) of the sea. In their skins there are tiny plants which act as "dustmen", taking some of the waste products from the corals and giving in return oxygen which the animal needs to breathe. If the plants are killed, or are even prevented from receiving light so that they cannot live normally, the corals will die.

单选题请根据下面征文回答第61～65题： One day a farmer went out for a walk with his son. The farmer put on a pair of wrong shoes, one with a thick sole(鞋底) and the other with a thin one. So as he began to walk, he felt very uncomfortable(不舒服). When he was just out of the house, he turned to his son and said, "Why should one of my legs be longer than the other today?" The son looked at his father's legs carefully as he was walking and then laughed, "Oh, no, Daddy, your legs are all right. You have put on the wrong shoes." The farmer was very happy to hear that and said to himself, "What a clever son I have got!" Then he asked his son to go back and get the other pair of shoes for him. The farmer had only two pairs of shoes. When the son ran back to the house, he found that the other pair was also a pair of wrong shoes. He had to return to his father with nothing in his hands and said out of breath (上气不接下气), " It' s no use changing them, Daddy! The shoes at home were not a pair, either!/
