10．—What would you do if it________tomorrow?

—We have to carry it on, since we've got everything ready.

A．rain B．rains

C．will rain D．is raining

答案：B 本题考查的是条件状语从句中的时态。句子意思是“如果明天下雨，你打算做什么？”所以从句谓语应该用一般将来时，在条件状语从句中要用一般现在时表示一般将来时，所以此题答案应选B项。

11．It is known to all that________you exercise regularly, you won't keep good health.

A．unless B．whenever

C．although D．if

答案：A 本题的意思是“人们都知道，除非你经常锻炼，否则你不会保持健康。”，选项B的意思是“无论何时”；选项C的意思是“尽管”；选项D的意思是“如果”。显然都不符合句意，此题的答案应该选择A项。

12．Visitors________not to touch the exhibits.

A．will request B．request

C．are requesting D．are requested

答案：D 本题考查的是被动语态以及request的用法。句意为“参观者被要求禁止触摸展品”，request是及物动词，根据句子的意思“游客被要求 ”可知要用被动语态，故答案应选D项。

13．The research is so designed that once________nothing can be done to change it.

A．begins B．having begun

C．beginning D．begun

答案：D 本题考查的是在状语从句中的省略情况。once引导的是一个条件状语从句。当从句主语与主句主语一致，从句中谓语是be或者从句主语是it，谓语是be的时候，可以将从句中的主语与be一起省略。D项省略了it is，所以此题应选择D项。

14．________much advice I gave him, he did exactly what he wanted to do.

A．How B．Whatever

C．However D．No matter

答案：C however引导让步状语从句。however后接形容词或副词。“无论给他多少劝告，他都完全按他所想的去做。”how不能引导让步状语从句，只能引导名词性从句。

15．I would appreciate it________you call back this afternoon for the doctor's appointment.

A．until B．if

C．when D．that

答案：B if引导条件状语从句，“如果你今天下午对与医生的约会打电话回来，我会非常感谢。”
