　　答案解析

　　1. C. 因为be believed /thought /supposed /said /reported等后要接动词不定式，排除A和B;又因为the flu与cause是被动关系，所以要用不定式的被动式。The flu is believed to be caused by...=It is believed /People believe that the flu is caused by...

　　2. B. 一是因为“发出香味”与“吸引游客”是同时发生的，且smell 作为连系动词没有被动形式，所以答案选B。

　　3. A. 因为the disc(唱片)与record(录制)是被动关系，这又是已经发生了的事，所以要用过去分词短语作定语(from www.yygrammar.com)。

　　4. B. 非谓语动词作状语时，其逻辑主语必须与句子主语一致。根据句意，受到攻击的应是“高楼”，而不是其他，故选B。

　　5. A。此题考查不定式的完成时。“据说他曾到国外留过学”，由studied可知“留学”这个动作已结束并发生在谓语动作is said之前，所以要用完成式。

　　6. A。此句考查过去分词作宾语补足语。句子结构较复杂,句中的that引导一个定语从句，它替代先行词the plan在从句中作see的宾语，the plan与carry out是被动关系，因此，用过去分词作宾补。即see the plan carried out the next year.

　　7. B。此题考查疑问词+不定式在句中作宾语。I know what to expect in my new job. 意为“我知道在新工作中期待什么”。

　　8. A。本句考查现在分词的完成时作状语。句意为“遭受如此严重的污染之后，现在净化这条河也许为时已晚了”。有already暗示可知suffer发生在clean up之前，因此要用现在分词的完成式作状语。

　　9. B。remain 作“尚待”解，要接不定式作表语，it是形式主语，指代whether they will enjoy it。see与it之间是动宾关系，因此用不定式的被动式。it remains to be seen是习惯用语，意为“还要看情况发展”。

　　10. D。“连词+分词”作状语时，其逻辑主语为句子的主语。句子主语与分词的之间是主动关系时用现在分词，被动关系用过去分词。the research与begin是被动关系，因此用过去分词begun(fromwww.yygrammar.com)。

　　11. C。此题的考查目标与NMET2000同。what to do with为常用搭配结构，意为“处置，利用”。句意为“据说澳大利亚有太多陆地，政府不知如何利用”。

　　12. B。find后面可以接由“宾语+ 现在分词/过去分词/ 不带to的不定式”构成的复合宾语结构。现在分词表主动，过去分词表被动，不定式表示动作已经发生。根据句意“如果厨师被发现在厨房吸烟，立即就会被解雇”可知cook与smoke之间是主动关系，应用现在分词。find sb. doing sth意为“发现某人正在做某事”。

　　13. B。考查不定式作定语。不定式作后置定语，一般用主动形式表示被动意义。句意为“今下午我要去超级市场，你有东西要买吗?”

　　14. C。考查过去分词作表语。句意为“飞机登陆时，飞行员要求所有飞机上的乘客坐着不动”。remain是系动词，seated作表语，表示状态。

　　15. C。考查动名词的复合结构作宾语。动名词的复合结构的否定式由“名词所有格或物主代词+not+动名词”构成。句意为“Victor因没能通知我计划的改变向我道歉”。
