2019年12月英语六级阅读理解：气候研究

The direct raya of the sun touch the equator and strike northward toward the Tropic of Cancer. In the Southern hemisphere winter has begun, and it is summer north of the equator. The sea and air grow warmer; the polar air of winter begins its gradual retreat.

The northward shift of the sun also brings the season of tropical cyclones to the northern hemisphere, a season that is ending for the Pacific and India Oceans south of the equator. Along our coasts and those of Asia. it is time to look seaward. to guard against the season's storms. Over the Pacific, the tropical cyclone season is never quite over. but varies in intensity. Every year. conditions east of the Philippines send a score of violent storms howling toward Asia, but it is worst from June through October. Southwest of Mexico. a few Pacific hurricanes will grow during spring and summer. but most will die at sea or perish over the desert or the lower California coast as squalls.

Along our Atlantic and Gulf coasts. the hurricane season is from June to November. In an average year, there are fewer than ten tropical cyclones and six of them will develop into hurricanes. These will kill 50 to 100 persons between Texas and Maine and cause property damage of more than $100 million. If the year is worse than average, we will suffer several hundred deaths,and property damage will run to billions of dollars.

Tornadoes, floods, and severe storms are in season elsewhere on the continent. Now, to these destructive forces must be added the hazard of the hurricane. From the National Hurricane Center in Miami. a radar fence reaches westward to Texas and northward to New England. It provides a 200-mile look into offshore disturbances. In Maryland. che giant computers of the National Meteorological Center digest the myriad bits of data-atmospheric pressure, temperature, humidity, surface winds. and winds aloft-received from weather stations and ships monitoring the atmospheric setting each hour, every day. Cloud photographs from spacecraft orbiting the earth are received in Maryland and are studied for che telltale spiral on the warming sea. The crew of United States aircraft over the Gulf of Mexico, Caribbean, and Atlantic watch the sky and wait for the storm that will bear a person's name. The machinery of early warning vibrates with new urgency as the season of great storms begins.

六级阅读理解答案：

1.南半球的热带气旋季节_________________。

A)是由冬季的极地空气所带来的

B)在南半球冬季到来的时候就结束了

C)实际上全年都存在

D)在太阳光照射到北回归线的时候就开始了

[B]从首段和第2段首句的描述可以知道，南北半球的气候相反，当南半球进入冬季、热带气旋季节结束的时候，北半球却是夏季、热带气旋季节开始的时候，辨清了这些事实，就不难判断选项B为本题答案。

2.下列关于刮向亚洲的风暴的说法那一点是正确的?

A)风暴产生干太平洋。

B)风暴对于东南亚的影响zui巨大。

C)风暴主要在春夏两季产生。

D)风暴通常在海岸边上消亡。

[A]第2段第3-5句说的是太平洋沿岸热带气旋的形成和影响，而且，如果稍有地理知识的话，就知道菲律宾东部也在太平洋上，结合第3、4句的内容就可以推断选项A为正确的说法。选项B没有原文依据;选项C和D都是第2段第5句提到的内容，是关于墨西哥西南部的飕风的，与亚洲的暴风无关。

4.对于迈阿密的飕风中心，我们了解到什么情况?

A)该中心主要为得克萨斯州和新英格兰地区遭飓风袭击时提供保护。

B)该中心对于龙卷凤，强烈暴风和飓风提出全国警报。

C)该中心在美国的西部和北部海岸都设有雷达。

D)该中心管理从得克萨斯到新英格兰的海岸地区。

[D]从末段第3句可以知道飓风中心的监测范围，第4句指出飓风中心主要监测的是海面的情况，结合这两句，即可知道选项D正确。选项A所表示的范围过小了，而选项B正好相反，范围过大;选项C中的the west and the north of U.S.(美国的西部和北部)与原文的westward to Texas and northward to New England所指的地点是不同的。

5.文章zui清晰的讨论点是____。

A)导致飓风的因素

B)受飕风危害风险zui大的地区

C)对于飕风的早期预警机制

D)解决由飓风造成的财产损失的方法

[C]末段提到了飓风中心和气象中心，说明了美国为了预警飓风所采取的措施，由此可见，选项C在文中是有清楚说明的。
