13、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最巨大。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
14、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。3.a西洋飓风到达下加州的时候大部分的罴塞基p鼍;agia)减弱强度c)造成重大财产损失 d)导致暴雨和洪水从第2段末旬中c die和perisb可以知道,多数太平洋踺风的强度会减弱并最终消逝,虽然句 yjsqualls-词为超纲间,但这不影响对垒句的p解,而且,从die和perish也可推断,squalls应该是强度不lihurricarles的暴风,由此可见,选项a为正确的说法。4.对于迈阿密的国家飕风中心,我们了解到什么情况?
15、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句可以知道国家飓风中心的监测范围,第4句指出国家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.文章最
16、清晰的讨论点是_。a)导致飓风的因素 b)受飕风危害风险最大的地区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末段提到了国家飓风中心和国家气象中心,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。参考译文1太阳直射光线接近赤道并向北回归线移动。南半球冬季开始了,而赤道北面则是夏季。海洋和天空变得温暖,冬天的极地气团开始逐渐减弱。1太阳北移也为北半球带来了热带气旋季节,而太平洋和印度洋的赤道以南部分却是这个季节的结束。沿着我国和亚洲的海岸,又到了监视海洋、提防夏季暴风的时候了。2在整个太平洋上空热带气旋季节从来就不会完全过去,只是强度会有所不同。每年
17、菲律宾东部一带会生成20个暴风咆哮刮向亚洲,但从6月直到整个10月是最糟糕的日子。2/3在墨西哥西南部,春季和夏季会生成几个太平洋飓风,但是大多数会在海上消亡,或者成为暴风雨而在沙漠的上空或加利福尼亚南部海岸消逝。在我国的太西洋和海湾沿岸,飕风季节从6月到11月。在一般的年份,热带气旋少于10个,有6个会发展成飓风。从得克萨斯州到缅因州,这些飓风令导致50到100人丧生,造成超过1亿美元的财产损失。如果是比一般年份更糟,就会有几百人丧生和高达几十亿美元的财产损失。此时大陆的其他地方正是龙卷风、洪水和猛烈暴风的季节。现在,除了这些破坏性的天气以外,还得加上飓风的危险。4在迈阿密的国家飓风中心,西
18、至得克萨斯州,北至新英格兰建起了一道雷达防护栏。它可以对离岸200英里的大气扰动进行监视。在马里兰州,国家气象中心巨型计算机对巨量的数据进行整理,这些数据包括从每时每日监测着大气状况的各个气象观测站台和观测船只接收到的大气压力、温度、湿度、表面风和高空风等等数据。马里兰州还接收从在地球轨道飞行的太空船发回的云图,研究在温暖海洋上空的那些先兆性气旋。在墨西哥湾、加勒比海和大西洋上空飞行的美国飞机上的机务人员监视着无空,等待着以一个人的名字书名的暴风到来。随着巨大暴风季节的开始,早期预警机制会对新的紧急状况迅速发出警报。英语四级阅读理解基础练习二upon reaching an appropria

28、,并自谋出路。父母不为子女安排婚姻,子女结婚也通常无需获得父母同意。在美国,浪漫的爱情往往是婚姻的基础,青年人通过朋友在学校、单位、组织以及宗教团体认识自己的,爱情的未来的伴侣。尽管子女自己择偶,他们仍然希望父母能认同他们的选择。许多家庭的父母认为,应由子女自己来做他们生活中的重大决定。家长可能会设法影响子女去从事某一职业,但子女也有选择其它职业的自由。有时为了证实自己的独立性,子女从事的工作正好与父母希望的相反。儿子可能执意不去父亲的企业工作,因为担心在那里就不能独立自主。这种不依靠父母的独立性并不意味着父母与子女之间缺乏爱心。父母和子女之间普遍都有挚爱,美国家庭也毫不例外。只不过在美国家庭
