III. 阅读理解：（共10小题；每小题1分，满分10分）
阅读下列短文，从每题所给的A、B、C、D四个选项中，选出最佳选项。
A
Violent ocean storms in the northern part of the world usually develop in late summer or autumn near the equator. When they happen over the northwestern Pacific Ocean, the storms are called typhoons. And, in the eastern Pacific and the Atlantic Ocean, they are called hurricanes. South of the equator, the winds flow in the same direction as the hands on a clock. North of the equator, they flow counter-clockwise.
Storms can result when the air temperature in one area is different from that of another. Warmer air rises and cooler air falls. These movements create a difference in the pressure of the atmosphere. If the pressure changes over a large area, winds start to blow in a huge circle. High-pressure air is pulled into a low-pressure center. Storms can get stronger and stronger as they move over warm ocean waters. Up to 50 centimeters of rain can fall. Some storms have produced more than150 centimeters of rain.
The scale is divided into 5 categories. A category one storm has winds of about 120 to 150 kilometers an hour. It can damage trees and lightweight structures. Wind speeds in a category two hurricane can reach close to 180 kilometers an hour. These storms are often powerful enough to break windows or blow the roof off a house. Winds between about 180 and 250 kilometers an hour represent categories three and four. Anything even more powerful is a category five hurricane. The researchers say that about 35% of all hurricanes in the past ten years were category four or five.
Weather scientists call hurricanes by names to make clear just which storm they are talking about, especially when two or more take place at the same time. They say using short names is especially important when exchanging storm information among weather stations and ships at sea. Weather scientists used the names of their girlfriends or wives for storms during World War Two. The United States weather service started officially using women’s names for storms in 1953. In 1978, realizing the sex prejudice of such names, it began including men’s names as well.
41. The first paragraph mainly _____.
A. tells us the areas where hurricanes come about B. confirms the position of typhoons
C. gives clear definitions of violent ocean storms D. explains the different changes near the equator
42. Storms move over warm ocean waters, making ____lower and the storms get stronger.
A. air pressure B. ocean water C. cool air D. warm air
43. If it makes some of the houses of a coast village fall down, the hurricane is ____ at least.
A. category 2 B. category 5 C. category 4 D. category 3
44. Hurricanes began to be given men’s names in 1978 because _____.
A. more women scientists studied hurricanes B. people wanted to show respect for women
C. women’s names were used too frequently D. men were jealous
45. Where is this passage most probably taken from?
A. A popular science book. B. A dictionary.
C. A university physics book. D. An advertisement.
B
“We leave at dawn and head out overland by jeep towards Base One. We will get as far as we can before proceeding on foot,” Mark explained. The others sat and listened. Sarah, particularly, as a “casualty of events”, wouldn’t have known what to say or even if she’d been asked. But Harry had a lot to say.
“We’ll never make it,” he protested. “We’ll still be crossing the desert when they catch up with us. They’ll know where we’re heading for and they seem to know every move we make or are going to make.” Mark said nothing, but spread his hands out as if to say “Well, what do we do then?” “We wouldn’t be in a mess now,” Harry went on, almost ignoring Mark’s gesture, “If we hadn’t stopped to rescue Sarah.” (He glanced at her briefly) “But since we did, we must get on — but not across the desert. There is the sand, and deep ravines which are almost invisible until you’re right on them and then the heat. You have to be used to going out there, and none of us is. This is no ‘morning at leisure’ on some pleasant holiday, you know! If we went north instead and made for the river…”
He broke off and looked around at the others, feeling somehow that his argument was pointless. No one said anything.
“Good,” said Mark, looked around with authority, and returned to checking their stores. A beautiful sunrise was about to burst over the horizon as the jeep headed out towards Base One.
46. It seemed clear from the passage that the group of people were_____.
A. being trained B. being hunted C. exploring D. practicing
47. Mark’s plan was that they should ______.
A. drive across the desert B. make for the river on foot
C. set off before dawn and leave Sarah D. drive as fast as possible, and then walk
48. Harry felt certain that ________.
A. they would escape B. they had a traitor
C. their situation was all Sarah’s fault D. they could hide in the desert
49. Why did Harry think that they should make for the river?
A. The desert heat would kill them. B. A river trip would be much safer.
C. The journey would be more pleasant. D. He knew the road leading north.
50. It can be inferred from the passage that _______.
A. none of them liked Harry B. Mark was the leader in the action
C. they wanted to see the sunrise D. they had no other choice but to wait |
