Section B
Directions: In this section, you will hear 3 short passages. At the end of each passage, you will hear some questions. Both the passage and the questions will be spoken only once. After you hear a question, you must choose the best answer from the four choices marked A, B, C and D.
听力原文： Men have been traveling across and around the equator on wheels, on their feet or in ships for thousands of years, but only a few men, with great difficulty and in very recent time, have ever crossed the ice to the North Pole. So it may surprise you to learn that, when traveling by air, it is really safer to fly over the North Pole than over the equator. Of course, this is not true about landings in the polar region (which passenger airplanes do not make), but the weather, if we are flying at a height of 5,000 meters above the Pole, is a delight. At 4,000 meters and more above the earth you can always be sure that you will not see a cloud in the sky as far as the eye can reach. In the tropics, on the other hand, you are not certain to keep clear of had weather even at such heights as 18,000 or 20,000 meters.
Airplanes can't climb as high or as quickly in cold air as in warm. Nor can clouds. In practice, this is an advantage to the airplane which is already at a good height when it reaches the polar region and so does not need to climb, while at the same time cold air keeps the clouds down low.

Section B
Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.
This was the memorial service for old Thomas Bevill, who had died before Christmas at the age of eighty-eight. When be was a Minister at the beginning of the war, I had been one of his personal staff. That had been my introduction to official life, and I knew him better than most of his colleagues did. No one, least of all himself, would have called him a great man, and yet I had learned much from him. In a limited sense of the word, he was a politician, a horn politician. He knew which levers to pull and how to pall them, more exactly than anyone I had met in Government, with a skill one meets more often in people working in a smaller world, such as Arthur Brown in my old college.
Bevill had passion for politics. Like most devoted politicians, he was realistic about everything in them—except his own chances. He had been dismissed, politely but firmly, in 1943, at the age of seventy-four. Everyone but himself knew it was the end. But he delayed taking his peerage (贵族爵位), still hoping that another Conservative government would call him back. New Conservative governments came, but the telephone did not ring. At last, at eighty-four, he accepted his peerage, even then hating it, even then going round asking his friends whether there might be the chance for one more job. When he was told no, his blue eyes ceased to look mild, and became hot any angry. But he surrendered. For the last four yearn, Thomas Bevill had entered another world, under the title of Lord Grampound.

A．The traffic next to campus.B．Horns at football games.C．Low-fiying airplanes.D．Loud e
