1.“Never for a second，”the boy says，“________that my father would come to my rescue.”(2013·江苏，27)
A.I doubted B.do I doubt
C.I have doubted D.did I doubt
答案 D
解析 句意为：这个男孩说：“我从不怀疑我父亲会来救我。”当否定副词或具有否定含义的短语置于句首时，句子常用部分倒装。故本题要用部分倒装。再根据would come to...可知，是在讲过去发生的事，故用过去时。

A.As B.If
C.Although D.Once
答案 C
解析 考查省略句中的连词选择。句意为：尽管很小，但是这个公司已经在30多个国家有1 000名左右的客户。as意为“因为”;if意为“如果”;although意为“尽管”;once意为“一旦”。

解析 6.The university estimates that living expenses for international students________around $8,450 a year，which________a burden for some of them.(2013·湖南，33)
A.are;is B.are;are
C.is;are D.is;is
答案 A
解析 考查主谓一致。句意为：这所大学估计，留学生的生活费用每年大约8 450美元左右，这对一些学生来说是一个负担。第一空的主语为living expenses指“生活费用”，谓语动词用复数形式;“which________a burden for some of them”是一个非限制性定语从句，which指代前面一句话，所以此处谓语动词用单数。
7.Not once________to Michael that he could one day become a top student in his class.
(2013·湖南，35)
A.occurred it B.it did occur
C.it occurred D.did it occur
答案 D
解析 考查倒装的用法。句意为：迈克尔成为班里的第一名这样的情况一次也没有发生过。否定词not置于句首，句子要用部分倒装。
8.Read this story，________you will realize that not everything can be bought with money.(2013·四川，4)
A.or B.and
C.but D.so
答案 B
解析 9.It was with the help of the local guide ________ the mountain climber was rescued.(2013·重庆，27)
A.who B.that
C.when D.how
答案 B
解析 考查强调句型。句意为：是在当地向导的帮助下，登山者才被营救出来。强调句型的结构是：It is/was+被强调部分+that...，故答案为B项。
10.Film has a much shorter history，especially when________such art forms as music and painting.(2012·新课标全国，32)
A.having compared to
B.comparing to
C.compare to
D.compared to
答案 D
解析 句子的主语是film，它和compare之间是被动关系，所以要用被动形式。因此只能选D项。“when compared to...”相当于when引导的状语从句的省略，补全后为：when it is compared to...。句意为：电影的历史短得多，尤其是它与诸如音乐、绘画等艺术形式相比较时。
11.Not until he retired from teaching three years ago ________having a holiday abroad.
(2012·辽宁，32)
A.he had considered
B.had he considered
C.he considered
D.did he consider
答案 D
解析 句首是“Not until”，表达否定意义的连词短语位于句首时要用部分倒装，因此可以排除A、C两项。再分析句子结构可知，本空所在是主句部分，结合从句时态可知主句用一般过去时态。句意为：直到在三年前从教学上退休后他才考虑到国外度假。
12.Only after Mary read her composition the second time________the spelling mistake.
(2012·天津，6)
A.did she notice B.she noticed
C.does she notice D.she has noticed
答案 A
解析 句意为：只有当玛丽再次读她的作文之后她才注意到这个拼写错误。“only+状语/状语从句”位于句首时，主句须用倒装语序。after引导的是时间状语从句，接在only之后，位于句首，所以主句要用倒装，可排除B、D两项。而且根据语境知read和notice都是过去发生的动作，所以答案为A项。
13.The basketball coach，as well as his team，________ interviewed shortly after the match for their outstanding performance. (2012·陕西，12)
A.were B.was
C.is D.are
答案 B
解析 考查动词时态和主谓一致。as well as连接两个名词或代词作主语时，谓语动词的数由第一个名词或代词决定。本题中主语中心词是the basketball coach，是单数;根据shortly after the match可以推断出题干时态是一般过去时，故选B。
14.All the photographs in this book，________ stated otherwise，date from the 1950s.(2012·陕西，25)
A.unless B.until
C.once D.if
答案 A
解析 考查状语从句。句意为：除非被特别标明，这本书中所有的图片都可以追溯到20世纪50年代。所填词表条件，从句用了省略句，unless意为“除非，如果不”，故选A。
15.It was not until I came here ________I realized this place was famous for not only its beauty but also its weather.(2012·湖南，30)
A.who B.that
C.where D.before
答案 B
解析 16.All the scientific evidence ________ that increasing use of chemicals in farming ________ damaging our health.(2012·湖南，35)
A.show;are B.shows;are
C.show;is D.shows;is
答案 D
解析 17.Never before________seen anybody who can play tennis as well as Robert.(2012·江西，32)
A.had she B.she had
C.has she D.she has
答案 C
解析 句意为：她从来都没有看到过任何人打网球和Robert一样好的。表示否定的副词never等放在句首，句子要用部分倒装结构，且本句时态为一般现在时。故选C项。
18.—Was it by cutting down staff ________ she saved the firm?
—No，it was by improving work efficiency.(2012·上海，37)
A.when B.what
C.how D.that
答案 D
解析 19.This is not my story，nor ________ the whole story.My story plays out differently.(2012·四川，5)
A.is there B.there is
C.is it D.it is
答案 C
解析 考查倒装句。nor位于句首引起部分倒装，排除B、D两项;再根据句意“这并不是(关于)我的故事，它也不是故事的全部。我的故事的结局不同。”用代词it指代前面的“this story”。故选C。
20.It sounds like something is wrong with the car’s engine.________，we’d better take it to the garage immediately.(2011·江苏，33)
A.Otherwise B.If not
C.But for that D.If so
答案 D
解析 句意为：听起来好像汽车的发动机出了故障。如果这样的话，我们最好马上把它开到维修厂(修理一下)。otherwise否则，要不然;if not如果不是这样的话;but for that要不是那样。以上三项均不符合句意。if so如果这样的话，符合句意。if so相当于if something is wrong with the car’s engine。
