语法专项练习【1】

C.is expected to be extended D. is expected to have extended
2. We advocate the economic, cultural and religious traditions of all national minorities.

3. There are two horses at the ends of a rope with all their might in opposite directions.

4. Today the Tennessee Valley is one of the richest areas in the world. But if things as they were it would now be a desert.

5.After twenty years abroad, William came back only how his hometown was damaged in an earthquake.
A. to find out B. finding out
C. to have found outD. to be finding out
1. D句子讲的是 “人们期待到21世纪前10年时,国际性商业航空交通远远超过当今水平”, 人们现在就期待, 而不是将来期待, 所以A、B是错误的; 另外, 表示到将来某一时刻为止已经完成的动作或出现的状态, 应用将来完成时, 按句意, 是指extend这一动作的完成, 所以应该在不定式上体现出来。根据上述分析, 选D符合句意要求。
2. C动词advocate后接动名词而不接不定式做宾语。D虽然是动名词, 但用其完成式在语义上讲不通。
3. Apulling是现在分词在句中做horses的定语, 相当于which pull。
4. Chad been left表示与过去事实相反的假设 “如果情况还像以前那样”。
5. A不定式to find out做结果状语,有意想不到的含义。不定式表示结果时, 用其一般式即可。
语法专项练习【2】
1. After people have learned that magnets attract things, centuries passed ____ they took note of the fact that magnets sometimes also repel things.
A. before B. until C. after D. since
2. He is off to Paris again tomorrow. He tells me that, with this journey, he ________ there and back twenty times.
A.will be B. will have been
C.will go D. will have gone
3. Many ways have been found_____small and simple machine to process large and complicated machine parts.
A. by using B. to use C. using D. used
4. I walked down the corridor, my footsteps_______frighteningly through the empty deserted building.
A. echoing B. echoed C. to echo D. having echoed
5. Apart from personal preferences, social context also affects—both directly and indirectly—the media and the media content to which you become exposed. For example, other members of the family often select media content that you _____, and you become exposed to it.
A. would not have selected B. should not have selected
C. must not select D. cannot have selected
1. Abefore应该理解成“(几百年过去了,人们) 才……”; 如果用after应该是…after centuries passed they took note of the fact…; 如果用until, 应该是they didn’t take note of the fact that…until centuries passed。
2. B此句意为：“他明天去巴黎,加上这次, 他就去了二十次了。”根据句意,应用将来完成时态。句中有back一词, 故D不合适。
3. Bto use…, 不定式短语做way的`定语, 只是因为定语太长,故将谓语前移,使句子避免头重脚轻。by using表示方式, 做状语用; using为动名词, 不能做way 的定语, way要求不定式做定语; used, 无论从语法结构上还是从意义上都讲不通。
4. A分词短语做伴随状语, my footsteps与echo的关系是主动的,因此用现在分词。另外, 分词做伴随状语表示与谓语动词的动作同时发生, 所以用其一般式。
5. A本句意为:“除了个人喜好外, 社会环境也会直接或间接地影响你使用的媒体和媒体的内容。例如, 家庭的其他成员常常选择的媒体内容你就未必选, 可是你也得使用。”句中暗含了 “如果是你, 你就不会选” 的意思, 所以用虚拟语气合适。should not have selected表示“本不应该选”; must not select表示“一定不要选”; cannot have selected表示“一定不能选”, 过于绝对。只有would not have selected 符合句意。
语法专项练习【3】
1. To understand the situation completely requires more thought than thus far.
A.has given B. was given C.being given D. has been given
2. Of great significance the nation-wide movement is the Kampuchean people in their heroic struggle against the aggression of the Vietnamese.

C. supportingD. of supporting
3. Many farmers came to the city, jobs and for all the other legendary opportunities of life in the city.
A. looking for B. to look for
C. having looked forD. looked for
4. It is requested that an applicant whose undergraduate work is done at another institution two copies of undergraduate transcripts and degrees directly to the dean of the graduate school.
A. must send B. send C. are to send D. need send
5. You her in her office last Friday; she’s been out of town for two weeks.
A. needn’t have seenB. might have seen
C. must have seen D. can’t have seen
答案解析：
1. D时间状语thus far“到目前为止”，与现在完成时连用，据此排除B、C。比较从句完整的结构应该是…than the thought which has been given thus far，可以把than 看做关系代词在从句中做主语，也可以把主语看做是省略了。
2. A题句由于主语较长，采用了倒装结构，可还原为：the nation-wide movement to support the Kampuchean people in their heroic struggle against the aggression of the Vietnamese is of great significance。movement要求不定式做定语，其他选项均不符合语法规则。
3. Alooking for…分词短语做came的伴随状语，如果选to look for做目的状语的话，不该有逗号。
4. B动词request要求其主语从句、宾语从句或同位语从句中谓语动词用(should+)原形表示虚拟。该句中that引导的是主语从句。
5. Dcan?t have done 表示对已发生的情况作否定推测“一定不是/没……”，根据句意只能选D。
