问题综合

（10分）图是我国30⁰N附近地形剖面及年平均气温、年平均降水量示意图。读图回答下列问题。

（1）剖面线上，东、西部年平均降水量的差异是　　　　　　　　　　　　　　　　　，其主要影响因素有　　　　　、　　　　　　。（3分）

（2）剖面线上，长江中下游平原与四川盆地相比，年太阳总辐射量较低的是　　，原因有　　　　　　　　　　　　　　　　　　　　　　　　　　　　　。（3分）

（3）长江中下游平原主要农业地域类型是　　　　　　　　　，发展该农业的有利社会经济条件有　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　。（4分）

答案

（1）东部多，西部少（1分）地形（1分）、大气环流（海陆位置）（1分）

（2）四川盆地（1分）阴雨、雾天多（1分），大气对太阳辐射的削弱作用强（1分）。

（3）水稻种植业（季风区水田农业）（1分）人口密集，劳动力丰富（1分）；粮食需求量大，市场广阔（1分）；种植历史悠久，经验丰富（1分）。

题目分析：

（1）直观的读图：年平均降水量四川盆地以东多，以西少；西部以高原为主，东部海拔低，地势低，以平原为主；东部地势低，夏季风影响大，降水多，西部地势高，受不到夏季风的影响，降水少。

（2）长江中下游平原与四川盆地相比，四川盆地四周高中部低，地形影响盆地内部多阴雨天气、雾天多，由于空气湿度大,尘埃、水汽多, 地势相对低,辐射穿过大气路程长,大气对太阳辐射的削弱作用强，年太阳总辐射量四川盆地比长江中下游平原低。

（3）长江中下游平原主要农业地域类型是水稻种植业；发展该农业的有利社会经济条件有人口密集，劳动力丰富；水稻种植产量高，能缓解人地矛盾；人口多粮食需求量大，市场广阔；种植历史悠久，经验丰富。；交通便利。

Basketball is still a young game. It's over a hundred years old. In the winter of 1891, a certain college was having some trouble with its boy students. The weather was bad and the students had to stay indoors. As they couldn't play outdoors, they were unhappy, and some even got into fights from time to time.

　　Some of the teachers, at the college asked Dr. Naismith to invent a game so that the students might have something to play with. It was not easy to invent such a game because it had to be played indoors , and the court (球场) was not very large.

　　Dr. Naismith thought for a few days and invented a kind of ball game. It was a fast, wonderful game with much moving and passing of the ball. It was played between two teams. To make a score , the ball had to be thrown into the basket ten feet(英尺) above the floor on the wall . At each end of the court there was such a basket. At first, Dr. Naismith wanted to throw the ball into a box. As he could not find boxes of the right size, he had to use fruit baskets instead. That is how the game got its name.

Questions 61—65 are based on Passage Two:Passage TwoAs the 21st century begins, a number of leaders in politics, education, and other professions believe that the US must adopt some new values to go along with the old traditional ones. What new values should Americans adopt This is a very difficult question to answer. Certainly, a greater value should be placed on the conservation of natural reasources; Americans should learn to use less and waste less. But conservation has never been a p value to Americans, who have believed that their country offered an endless,abundant supply of natural resources.Recently, progress has been made—more and more Americans are recycling their paper,cans,bottles,and other goods—but old wasteful habits died hard. Furthermore,the need to protect the environment may conflict with the need for jobs,as in the Northwest ,where conservationists battle lumber companies that want to cut down ancient redwood trees. A belief in the value of conservation is still compared with other American values; it can become per only as Americans see the need for it more clearly.In addition,Americans may need to place a p value on cooperation on a national scale to achieve important national objectives. The American idea of the national good has never been based on national cooperation but rather on the freedom of the individual, maintaining those conditions that provide the greatest freedom and prosperity for the individual . It is far more difficult for Americans to accept shared sacrifice for the common good and wellbeing of the entire country. For example ,although the majority of Americans believe that it is extremely important to balance the national budget and reduce the deficit, they do not want to see cuts in government programs that benefit them personally.The American value of competition also hinders the development of a spirit of national cooperation. Competition sometimes encourages feelings of suspicion rather than the mutual trust that is necessary for successful national cooperation.Although Americans often cooperate successfully on the local level—in neighborhood groups and churches, for example, on the national level, they may see themselves as part of an interest group that is competing with other interest groups for government funds. A request by the national government for shared sacrifice may be seen as coercive and destructive rather than voluntary and constructive. However, the demands for the 21st century may compel Americans to place a greater value on national cooperation to solve problems that affect them all, directly and indirectly.

The author gave an example in the third paragraph in order to ().

A．emphasize the need to place a per value on national cooperation

B．explain why the American idea has been based on individual freedom

C．illustrate the fact that the Americans will not sacrifice their personal interest for the good of the entire country

D．support the idea that Americans need the spirit of national cooperation to achieve important national objectives in the 21st century
