[简答题]Museums are, like everything else, products of history. They have all changed a great deal over time and can change again. They need to. Museums spring, essentially, from the Enlightenment. The British Museum was founded in 1753, a century-and-a-half after Galileo, but a hundred years before Darwin. The rapidly accumulating collections in the world’ s first public museums were a by-product of the birth of modern science, when researchers made discoveries by building collections—a devil’s toenail, for example, entered museums as an object of wonder only later to be re-labeled as the fossil of an extinct oyster.
In our post-Enlightenment age, the visible world has lost much of its mystery (which is perhaps why we care so little for it). Collecting is no longer a key method of research. Nor might so many people have visited museums in the past if they had been able to hop on a plane to see a kangaroo for themselves, or buy a book of color reproductions of Japanese print

[单项选择]Questions 16-20 are based on the following passage.
I heard many parents complaining that their teen-age children are rebelling. I wish it were so. At your age you ought to be growing away from your parents. You should be learning to stand on your own two feet. But take a good look at the present rebellion. It seems that teen-agers are taking the same way of showing that they disagree with their parents.

They claim they want to dress as they please. But they all wear the same clothes. They set off in new directions in music. But somehow they all end up huddled round listening to the same record. Their reason for thinking or acting in thus-and-such a way is that the crowd is doing it. They have come out of their cocoons (茧) and entered a larger one.
