20、als.课时作业(九)阅读理解A【语篇解读】观鲸船所产生的噪音给虎鲸之间的信息交流造成了困难。1答案与解析：D主旨大意题。概括文章第一段可得出答案。观鲸船所产生的噪音给虎鲸之间的信息交流造成了困难。A项所涉及的范围过大；B项仅仅是文章的细节；C项与原文信息不符，因为文章最后说明虎鲸数量下降的原因不明。因此选D项。2答案与解析：B细节理解题。文章第五段说明，因为受噪音干扰，现在虎鲸“唱”的时间比原来长。3答案与解析：C推理判断题。文章介绍了观鲸船所产生的噪音给虎鲸之间的交流造成了困难，从文章最后的叙述看，虎鲸数量在下降，而科学家也不明白其中原因，显然作者对虎鲸的生存状况感到“担忧”。4答案与解析
21、：C推理判断题。从文中第三段和倒数第三段可以看出鲸是靠声波交流捕猎和繁殖信息的，如果这些事情被阻止了，鲸的数量就会下降。B【语篇解读】本文为记叙文，讲述了17岁的美国少年Zac Sunderland驾驶着他的帆船历时13个月，航行28 000海里的故事。5答案与解析：B数字计算题。根据第一段中的“complete a hard 13month voyage”和第四段中的“Sunderland left Marina Del Rey.on June 14,2008”可以计算出，Sunderland是在2009年7月完成他长达13个月的环球航行的，故选B。6答案与解析：C数字计算题。根据第三段可知
22、，美国帆船协会的数据显示，曾独自驾船环游地球的人不到250个，而登上珠穆朗玛峰顶峰的人数却是它的三倍，故选C。7答案与解析：D细节理解题。根据第五段第一句可知，在Sunderland行至墨西哥附近的海域接近旅途结束的时候，帆船的隔板坏了，所以他不得不停靠在巴亚尔塔港，直到他的父亲乘飞机赶到为他修理帆船，故选D。8答案与解析：A词义猜测题。根据第六段可知，Sunderland在进入墨西哥水域前把那支枪扔了，因为在那里私带枪支是违法的。abandon“遗弃，抛弃”，故选A。C【语篇解读】本文是一篇应用文。文章介绍了四部在电影之夜展播的与海洋有关的优秀电影。9答案与解析：C细节理解题。由第五段首句可知，在Finding Nemo这部电影中，鱼的记忆力很好。故选C。10答案与解析：B细节理解题。由Free Willy部分可知，Jesse帮助一条被困的虎鲸返回了家。故选B。11答案与解析：C推理判断题。由第二段第一句“We start this movie season.the site for the series.”可知，电影节播放的这些电影是以海洋为主题的，因此推断，喜欢海洋生活的青少年最有可能对这篇文章感兴趣。故选C。
