Ⅳ.阅读理解
Most of the sandstorms that had swept China last year originated from foreign land，a Chinese official in charge of desertification control said Monday.And the invasions(入侵) could partly explain the frequent sandstorms in the country in recent years despite its achievements in desertification control.
Since the start of last spring，the north and northwestern Chinese regions had been hit by 17 sandstorms，of which，a dozen came from foreign land.
Situated in the centralAsia sandstorm region，one of the world's four largest sandstorm sources，China also suffers from sandstorms from outside the country while being blamed as a sand source to northeast Asia.The other three major sources are in Africa，North America and Australia.
The land suffering from desertification has been decreasing by 7,585 sq.km annually in China，and the area of sandy land has also been falling by 1,284 sq.km a year.
The shrinkage(收缩) forms a clear contrast to the fact that the land suffering from desertification and sandy feature was added by 10,400 sq.km and 3,436 sq.km late last century，respectively.
Currently，the desertification land in China makes up 2.64 million sq.km，accounting for 27.46 percent of the nation's land，and its sandy land totals 1.74 million sq.km，accounting for 18.1 percent of the country's total.

【答案】 1－5 CFAEB
【语篇解读】 俗话说得好，一个人最大的敌人就是他自己。文章向我们介绍了如何直面我们内在的敌人：恐惧、优柔寡断和怀疑。
1．C C项承上启下，设空处前一段讲恐惧是存在于我们心中的敌人，而下文分别讲的是优柔寡断和怀疑这两个另外的敌人。故选C项。
2．F 设空处前一句是一个比喻，故设空处应为对前一句的进一步解释。前一句中有两个关键词，一个是thief，另一个是opportunity，故要寻找对这两个词进行解释的句子。对照所给选项可知，F项中有steal(对thief的解释)和chances for a better future(对opportunity的解释)。故此处应选F项。
3．A 本段的主旨词是doubt。由设空后的关键词But可知，设空处内容应该与But后的内容相对，根据But后的内容可推知，设空处应为表示怀疑的合理性的内容。所给选项中有三项涉及怀疑(A项、E项和G项)，但表示怀疑的合理性的只有A项，故为正确答案。
4．E 上文讲了“怀疑”的各种坏处，下面自然是建议要克服这个内心的敌人，故选E项。
5．B 此处承接上文，总结全文。上文提到要和恐惧作斗争，下文鼓励读者要勇敢面对生活，追求自己的梦想。由此可知设空处应为表示鼓励读者要有勇气的话语，故选B项。
