You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the centre. ��

　　Questions 21 to 23 are based on the following passage: ��

　　The Caledonian Market in London is a clearing house of the junk (舊貨、廢棄物 ) of the universe. Here, rubbish is a commodity and rubbish picking is a sport. Somebody, somewhere, wanted these things, perhaps just to look at. You learn here the incredible obscurity of human needs and desires. People grope (摸索), with fascinated curiosity, among the turned�瞣ut debris (廢墟) of thousands of attic rooms. Junk pours in twice a week, year in and year out. The Market is the penultimate (倒數(shù)第二的) resting place of banished vases, musical instruments that will not play, sewing machines that will not sew, paralyzed perambulator, epileptic bicycles and numerous other articles from which all morale and hope have long departed. There are stories of fortunes being picked up in the Market. Once seven hundred gold sovereigns were found in a secret drawer of a crazy old bureau. And book buyers have discovered valuable editions of Milton and Dickens and Carlyla. There is nothing one can not buy in the Market. ��

　　Questions 24 to 30 are based on the following passage: ��

　　A llelomimetic behavior may be defined as behavior in which two or more individual animals do the same thing, with some degree of mutual simulation and coordination. It can only involve in species with sense organs that are well enough developed so that continuous sensory contact can be maintained. It is found primarily in vertebrates(脊椎動物), in those species that are diurnal, and usually in those that spend much of their lives in the air, in open water or on open plains.��

　　In birds, allelomimetic behavior is the rule rather than the exception, though it may occasionally be limited to particular seasons of the year as it is in the redwing blackbird. Its principal function is that of providing safety from predators(掠食者), partly because the flock can rely on many pairs of eyes to watch for enemies, and partly because if one bird reacts to danger, the whole flock is warned.��

　　Among mammals, allelomimetic behavior is very rare in rodents(嚙齒動物), which almost never move in flocks or herds. Even when they are artificially crowded together, they do not conform in their movements. On the other hand, such behavior is a major system among large�瞙oofed mammals,such as sheep.��

　　In the pack�瞙unting carnivores(食肉類飛禽), allelomimetic behavior has another function of cooperative hunting for large prey(被捕食者) animals,such as moose. Wolves also defend their dens as a group against larger predators, such as bears.��

　　Finally, allelomimetic behavior is highly developed among most primate groups, where it has the principal function of providing warning against predators,as though combined defensive behavior is also seen in troops of baboons(狒狒). ��
