60、袖都已经采取措施，展开行动，消灭蝗虫。电台也呼吁更多的人加入与蝗虫的战斗中来。1D推理判断题。根据第一段Parts of Africa are covered by a dark cloud. But this is no rain cloud. It is a living cloud made of billions of locusts (蝗虫) that are travelling across the continent eating everything in their path.可知，非洲部分地区被乌云覆盖，但这并不是雨云，而是由数十亿只蝗虫组成的活云，它们正在穿越非洲大陆，
61、吃掉路上的所有东西。由此可推知，这里是用乌云来形容蝗虫的数量、速度和危害。故选D。2D主旨大意题。结合文章主要讲的是非洲西部发生的严重的蝗虫灾害，而且各方正为消灭蝗虫而做着努力。由此可知，文章主要讲述的是一场与西非蝗虫带来的灾难作斗争的故事。故选D。3B细节理解题。根据第四段中“We are now treating 6，000 hectares per day with pesticide, but we need to treat 20，000 hectares per day in order to have any hope of controlling this disaster，”
62、 said Mohamed Abdallahi Ould Babah, director of locust control in Mauritania.可知毛里塔尼亚蝗虫控制中心主任Mohamed Abdallahi Ould Babah说：“我们现在每天要用杀虫剂处理6，000公顷有蝗虫的土地，但是我们每天需要处理20，000公顷有蝗虫的土地，这样才有希望控制这场灾难。”由此可知，蝗虫灾害目前失去了控制。故选B。4C细节理解题。C选项“蝗虫能造成这样的破坏主要是因为它们在西非没有天敌”文章没有提到，所以C项错误。A、B、D三项均能从原文中找出对应信息，均正确。故选C。.语法填空 阅读下面材
63、料，在空白处填入适当的内容(1个单词)或括号内单词的正确形式。Living beside an active volcano(火山) means that small earthquakes are not unusual.Everybody here knows 1 what they feel like，and they come 2 as no surprise to the local people.For me，theyre a little different, though.What do you do when theres an earthquake?

66、w seconds.I had spoken to the local people since the event and，9 luckily (luck), there were no injuries or damage 10 done (do) by it.But if it had been a real earthquake, I think I would have felt quite differently.答案及解析：【语篇解读】文章中作者结合自己经历的一次小地震，介绍了地震发生时应该怎么做。1what考查宾语从句。设空处引导宾语从句，作介词like的宾语且表示“什么”之意
67、，故填what。2as考查介词。come as no surprise意为“来得不稀奇，发生在意料之中”。3the考查定冠词。序数词前应用定冠词限定，故填the。4to be trapped考查不定式的被动式。want后跟带to的不定式作宾语，又因trap与nobody之间是逻辑上的动宾关系，故填to be trapped。5running考查非谓语动词。设空处与hiding somewhere并列作such as的宾语，故填running。6that/which考查定语从句。设空处引导限制性定语从句修饰先行词earthquake，且在从句中作主语，故填that/which。7frightened考查形容词。设空处作表语，表示“人感到害怕的”，故填frightened。8lasted考查时态。由语境可知，此处描述的是发生在上周的事情，应用一般过去时，故填lasted。9luckily考查副词。设空处作状语修饰分句there were no injuriesby it，故填luckily。10done考查非谓语动词。设空处作后置定语修饰injuries or damage，又因do与injuries or damage之间是逻辑上的动宾关系，故填done。
