No matter how long your life is, you will, at best, be able to read only a few books of all that have been written, and the few you do read should include the best. You can be pleased with the fact that the number of such is relatively small.

It is to be expected that the selections will change over time. Yet there is a surprising uniformity (一致性) in the lists which represent the best choices of any period. In every age, the list makers include both ancient and modern books in their selections, and they always wonder whether the moderns are up to the great books of the past.

What are the signs by which we may recognize a great book? The four I will mention may not be all there are, but they are the ones I’ve found most useful in explaining my choices over the years.

Great books are probably the most widely read. They are enduring best sellers. Gone with the Wind has had relatively few readers compared to the plays of Shakespeare or Don Quixote. It would be reasonable to estimate that Homer Iliad has been read by at least 25,000,000 people in the last 3000 years.

Great books are popular, not pedantic. They are not written by specialists about specialties for specialists. Whether they are philosophy or science, or history or poetry, they treat of human, not academic problems. They are written for men, not professors. To read a textbook for advanced students, you have to read an elementary textbook first. But the great books can be considered elementary in the sense that they treat the elements of any subject matter. They are not related to one another as a series of textbooks, graded in difficulty or in the technicality of the problems with which they deal.

Great books are always contemporary, the most readable and instructive.

Great books deal with the continuously unsolved problems of human life. There are mysteries in the world that mark the limits of human knowing and thinking. Inquiry not begins with wonder, but usually ends with it also. Great minds acknowledge mysteries only honestly. Wisdom is encouraged, not destroyed, by understanding its limitations.

盛世爱马，末世爱驴。“欲饮琵琶马上催”，这是初唐诗人王翰的句子；“细雨骑驴入剑门”，这是南宋诗人陆游的句子。诗人的话当不了真，何况还是酒话。因为这两个句子前，是“葡萄美酒夜光杯”和“衣上征尘杂酒痕”，都喝过酒了。把这两个句子一比，骑驴的陆游即使豪放，也显出几分落拓。马也好，驴也好，只是到了诗人那里，他更爱的是酒。所以有了李白的“五花马，千金裘，呼儿将出换美酒”了。
这段话的主旨是（）。

A．盛世爱马，末世爱驴

B．诗人的话不可当真，何况是酒话

C．马也好，驴也好，诗人更爱的却是酒

D．南宋陆游虽然落拓，但他却正是末世爱驴的典型实例
