Questions 21 to 23 are based on the following passage:

The Caledonian Market in London is a clearing house of the junk (旧货、废弃 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out debris (废墟) of thousands of attic rooms. Junk pours in twice a week, year in and year out. The Market is the penultimate (倒数第二的) 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.
