[单项选择]
If you are like most people, your intelligence varies from season to season. You are probably a lot sharper in the spring than you are at any other time of the year. A noted scientist, Ellsworth Huntington (1876-1947), concluded from other men’s work and his own among peoples in different climates that climate and temperature have a definite effect on our mental abilities.
He found that cool weather is much more favorable for creative thinking than is summer heat. This does not mean that all people are less intelligent in the summer than they are during the rest of the year. It does mean, however, that the mental abilities of large numbers of people tend to be lowest in the summer.
Spring appears to be the best period of the year for thinking. One reason may be that in the spring man’s mental abilities are affected by the same factors that bring about great changes in all nature.
Fall is the next-best season, then winter. As for summer, it seem
A. several times throughout the year
B. during spring and fall
C. during the summer
D. as seldom as possible

[填空题]They were, by far, the largest and most distant objects that scientists had ever detected: a strip of enormous cosmic cloud some 15 billion light-years from earth. 71. But even more important, it was the farthest that scientists had been able to look into the past, for what they were seeing were the patterns and structures that existed 15 billion years ago. That was just about the moment that the universe was born. What the researchers found was at once both amazing and expected: the US National Aeronautics and Space Administration’’s Cosmic Background Explorer satellite―Cobe―had discovered landmark evidence that the universe did in fact begin with the primeval explosion that has become known as the Big Bang (the theory that the universe originated in an explosion from a single mass of energy).
72. The existence of the giant clouds was virtually required for the Big Bang, first put forward in the 1920s,to maintain its reign as the dominant explanation of the cosmos. According to the
