20、ca.D12 countries affected by locusts have united but still lack pesticide.C答案及解析：【语篇解读】这是一篇说明文。这篇短文讲述的是非洲的部分地区遭受了非常严重的蝗虫灾害，造成了很大的损失。现在政府及其他国家的领袖都已经采取措施，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 billi
21、ons 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，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 treatin
