单选题The square is 500 yards wide, five times______the size of St. Peter's in Rome.

单选题Suppose you have a brick and a sponge which are exactly the same size. The brick and the sponge will occupy the same amount of space, but they will not weigh the same. If two things are exactly the same size, but differ in weight, then they have different densities. The one with the greater weight for the same size has the greater density. The one with lower weight for the same size has the lower density. Now apply this idea to fluids. You know that water and air expand when they are heated and therefore become less dense. If you poured a cupful of very hot water and let it cool, you would have a little less than a cupfull of cool water. If you weighed a cupful of very hot water and a cupful of cool water, the cupful of very hot water would weigh a little less. The cupful of cool water, being a little heavier than the cupful of hot water, would really have a little more water in it. Cold water is denser than hot water. Likewise, cold air is denser than hot. air. The greater weigh! of !he denser material makes it fall to the bottom of the container. It pushes up the less dense material.

单选题According to a survey, which was based on the responses of over 188,000 students, today's traditional-age college freshmen are "more materialistic and less altruistic (利他主义的)"than at any time in the 17 years of the poll. Not surprising in these hard times, the student's major objective "is to be financially well off. Less important than ever is developing a meaningful philosophy of life." It follows then that today the most popular course is not literature or history but accounting. Interest in teaching, social service and the "altruistic" fields is at a low. On the other hand, enrollment in business programs, engineering and computer science is way up. That's no surprise either. A friend of mine (a sales representative for a chemical company) was making twice the salary of her college instructors her first year on the job--even before she completed her two-year associate degree. While it's true that we all need a career, it is equally true that our civilization has accumulated an incredible amount of knowledge in fields far removed from our own and that we are better for our understanding of these other contributions- be they scientific or artistic. It is equally true that, in studying the diverse wisdom of others, we learn how to think. More important, perhaps, education teaches us to see the connections between things, as well as to see beyond our immediate needs. Weekly we read of unions who went on strike for higher wages, only to drive their employer out of business. No company; no job. How shortsighted in the long run! But the most important argument for a broad education is that in studying the accumulated wisdom of the ages, we improve our moral sense. I saw a cartoon recently which shows a group of businessmen looking puzzled as they sit around a conference table; one of them is talking on the intercom (对讲机): "Miss Baxter," he says, "could you please send in someone who can distinguish right from wrong?" From the long-term point of view, that's what education really ought to be about.
