9) 非谓语动词的体

　　非谓语动词中分词的体有完成体和进行体，即having done, having been done和being done，完成体只用于做状语的场合，而进行体可以用于做定语和做补足语。

　　动名词的体也有having done, having been done和 being done的结构主要用于做主语和宾语的场合。

　　不定式的体有to be doing 和to have done，主要用于pretend, happen, seem, appear, be said to等结构中。如：

　　① The man in the corner confessed to _____ a lie to the manager of the company.(1997.6)

　　A. have told B. be told C. being told D. having told

　　having told在句中做介词宾语，表示动作发生在谓语动词之前。

　　② I'd rather read than watch television; the programs seem ____ all the time.(1997.1)

　　A. to get worse B. to be getting worse C. to have got worse D. getting worse

　　从all the time的使用可以推断get worse是一个渐变过程，所以用不定式的进行体。

　　③ The speech _____ a lively discussion started.(1995.1)

　　A. being delivered B. was delivered C. be delivered D. having been delivered

　　该结构属于独立主格结构做时间状语，状语分词所表示的动作发生在谓语动词之前，所以应该用完成体，答案为D。

　　10)动名词复合结构

　　动名词符合结构可以做主语、宾语和表语，在对动名词的考查中总是将其逻辑主语包括进来，形成动名词的复合结构：

　　① _____ in an atmosphere of simple living was what her parents

　　wished for.(1999.1)

　　A. The girl was educated B. The girl educated

　　C. The girl's being educated D. The girl to be educated

　　本题涉及题眼比较多，A，为从句做主语，但缺少that，D为不定式做主语，但缺少for(for the girl to be educated)，B结构不能做主语，答案是C，为动名词的复合结构。

　　② Ann never dreams of _____ for her to be sent abroad very soon.

　　A. there being a chance B. there to be a chance

　　C. there be a chance D. being a chance

　　介词后用动名词，表示存在时必须用there be句型，所以答案为A，这也是动名词复合结构，there为动名词的逻辑主语。

　　③ I don't mind _____ the decision as long as it is not too late.

　　A. you to delay making B. your delaying making

　　C. you delaying to make D. you delay to make (2000.1)

　　Mind要求接动名词,动名词的逻辑主语用形容词性物主代词，答案自然是B。

　　④ I would appreciate _____ it a secret.(1995.6)

　　A. your keeping B. you to keep C. that you keep D. that you will keep

　　本题与上一题类似，答案是A。

　　2.非谓语动词解题策略

　　1)正确判断非谓语动词

　　这类题一般出现在独立主格结构中，如果在选项与句子之间没有连词，则说明，所选为独立主格结构，既名词或主格代词 + 分词。

　　All things ______, the planned trip will have to be called off.

　　A. considered B. be considered C. considering D. having considered (1998.6)

　　句子没有连词，说明所选结构不属于从句，那么就是独立主格做状语，根据动词与其逻辑主语之间的关系为动宾关系，答案应该是A。

　　____, a man who expresses himself effectively is sure to succeed more rapidly than a man whose command of language is poor.(1997.6)

　　A. Other things being equal B. Were other things equal C. To be equal to other things D. Other things to be equal

　　做状语的可以是从句，但B的结构是虚拟条件，与这里不符，不表目的，C不对，不表将来，独立主格中非谓语动词不能是不定式，答案为A。

　　4) 判断动名词复合结构的方式

　　主语位置上，或动词、介词后的"名词代词 + 非谓语动词"，如果表示的是一个事件则是动名词复合结构，而不是"名词 + 定语。请看以下各例：

　　He insisted on the windows _____ open while he was sleeping.

　　A. left B. being left C. leaving D. be left

　　insist on后不接从句，D可以排除。这里表达的是坚持要求"开着窗子睡觉"，所以应该是动名词复合结构，答案为B。

　　The road __________ caused us to be for our work for half an hour.

　　A. blocked B. was blocked C. blocking D. being blocked
