[简答题]The first outline of The Ascent of Man was written in July 1969 and the last foot of film was shot in December 1972. An undertaking as large as this, though wonderfully exhilarating, is not entered lightly. It demands an unflagging intellectual and physical vigour, a total immersion, which I had to be sure that I could sustain with pleasure; for instance, I had to put off researches that I had already begun; and I ought to explain what moved me to do so.
There has been a deep change in the temper of science in the last 20 years: the focus of attention has shifted from the physical to the life sciences. As a result, science is drawn more and more to the study of individuality. But the interested spectator is hardly aware yet how far reaching the effect is in changing the image of man that science moulds. As a mathematician trained in physics, I too would have been unaware, had not a series of lucky chances taken me into the life sciences in middle age. I owe a debt for the good f

[单项选择]Washington Irving was the American first man of letters to be known internationally. His works were received enthusiastically both in England and in the United States. He was, in fact, one of the most successful writers of his time in either country, delighting a large general public and at the same time winning the admiration of fellow writers like Scott in Britain and Poe and Tarwthorne in the United States. The respect in which he was held was partly owing to the man himself, with his warm friendliness, his good sense, his politeness, his gay spirits, his artistic integrity, his love of both the old World and the New.

In England he was granted an honorary degree from Oxford -- an unusual honor for a citizen of a young, uncultured nation -- and received the medal of the Royal Society of Literature; America

[填空题]Freud was the first man to help mental patients by having them talk about what made them anxious.

[填空题]Leonardo da Vinci was the first man to suggest that growing trees add a ring in their trunks each year. The (47) is these rings relates to the physical conditions which the tree experiences. Thus, trees grown in a (48) area and time each develop a pattern or configuration of their rings.
This (49) was of little significance until Andrew E. Douglas began to study tree rings in Arizona in 1600. Using a technique called cross dating, he was able to employ tree rings to the study of archaeological sites and date the ruins with (50) . Some were as old as 6700 B.C. ! This study of tree rings is called dendrochronology(树木年代学).
In time the cross dating was (51) by a carbon 14 process. This approach measured the amount of carbon 14 radiating from a piece of wood and (52) determined the age of that wood. Further use of the carbon 14 technique has shown that the radiation process is more complex and less (53)
