【解析】"believe it or not""信不信由你，我说的是真的"，这是口语中的一种习惯用语。
4.答案a)
【译文】竞争的压力使得美国人精力旺盛，但同时也使他们长期处于情绪紧张的状态。
【解析】名词pressure后接动词不定式作其定语。类似的名词还有ability, attempt, freedom,right,opportunity等。例如：

【译文】我曾听到和都称赞他。
【解析】不定式在feel,hear,listen to,look at,notice,observe,perceive,see，sense,watch等感官动词后面作宾补时，to省略。也可以用现在分词作宾语补足语。不定式表示动作的全过程，现在分词表示动作正在进行。例如：
i felt something touch/touching my foot.我觉得有什么东西碰了我的脚。
did you notice anyone leave/leaving the house?你看到有人离开这房子了吗？
7.答案c)
【译文】这项将于2000年前完工的工程将扩大城市的电话网至1,000,000用户。
【解析】分词和不定式都可作定语。现在分词作定语，表主动、进行；过去分词作定语，表被动、完成；不定式作定语，表将来。根据时间状语by the end of 2000,可知该定语应表示将来完成时。例如：
there are more than fifty proposals to be discussed at tomorrow’s conference.明天的会上将讨论50多条建议。
there were more than fifty proposals discussed at the conference.会上讨论了50多条建议。
8.答案c)

【解析】当谓语动词为believe,report,say,suppose等时，其后需用动词不定式作主补，表示发生在过去的事，动词不定式用完成时。有关动词不定式的时态可归纳如下：表示动作或状态与谓语动词表示的动作同时发生或在其后发生，用一般式；表示的动作在谓语动词表示的动作之前发生，用完成式。例如：
mrs.brown is supposed to have left for italy last weeks.据猜测，布朗夫人上周去了意大利。

【解析】动词不定式作宾补时，如果动词为使役动词have,make,let或感官动词see,feel,sense,hear,watch等，该不定式省略to。
11.答案c)
【译文】这个原本月底完工的建设项目如果延期了，这家公司将被处以罚金。
【解析】根据时间状语by the end of this month,应选择不定式作定语，表示动作将要发生，动词complet与其所修饰的名词the building project为被动关系，因此用不定式的被动式。
