五、不定式作状语

注意作状语的动词不定式要与其逻辑主语在意义上和数上的一致。

1. 表示目的

22） its plans to promote disarmaments，the party has decided to establish a campaign headquarters with Benjamin Seaman as its leader.

［A］Although［B］To carry out［C］Except that［D］ Make

23） pure lead，the lead ore is mined，then smelted，and finally refined.

［A］ Obtaining［B］ Being obtained［C］ To obtain［D］ It is obtained

24） When they met，Leonardo and his enemy were fighting .

［A］killed each other［B］killing each other［C］to be killed each other

［D］to kill each other

2. 表示结果，在这种情况下，不定式的逻辑主语也是全句的主语

He must be cripple not to walk by himself./It seems that the employee didn't sleep at all to be so sleepy in the early morning. / What have I done for you to deserve such an amount of money？

还有固定搭配的不定式表示结果：so…as to； such（…） as to …； enough to…； too…to…； in order to … 等

We have got so plenty of food as to treat our guests./ Is that room big enough to seat all of us？/ He is too young to fit that job.

3. 表示原因

It's very kind of you to say so. / I am pretty pleased to hear the news that you are elected as the president of the club. / I'm sorry to interrupt you. / They are quite surprised to see the great changes taking place in the area.

4. 伴随状况

在下列表示能力、愿望、倾向等语义的形容词后边也要接不定式：able（但其同义词“ capable”后面要接“of+动名词”），anxious， eager， glad， inclined（倾向于），liable， likely， pleased， ready等。

25） Certain ［A］ minerals are magnetic and are able to detected ［B］ by instruments that measure ［C］ differences in the Earth's magnetic fields ［D］ .

六、 在复合结构中的不定式

不定式的复合结构是指有些动词带宾语后再带上不定式，作宾语的补足语。前边已提到过，在这种结构中宾语是不定式的逻辑主语。

1. 有很多这样的动词可以跟宾语及其（或）补足语不定式，如：advise， allow， ask， enable， beg， cause， drive， encourage， expect， forbid， force， hate， get ， intend， invite， like， permit， persuade， pretend， remind， say， teach， tell， trust， urge， want， warn等表示“致使”等意义

26） The company manager may enable the men who tend the machines a large panorama（全景） of possibilites.

［A］ to see［B］ see［C］ seeing［D］ seen

27） Did you intend us the new method？

［A］ to use ［B］ using ［C］ our having used ［D］ the using of

28） The teacher encouraged good compositions.

［A］ us write［B］ us writing［C］ us to write［D］ our wrting

2. 在某些成语动词如 arrange for， call on， care for， count on， count upon， depend upon， long for， prepare for， prevail upon， rely on， vote for， wait for等后面，也可以跟宾语加不定式的复合结构

We are waiting for the bus to come./ They voted for Wang Gang to be the monitor. / Don't count on me to do that.

3. 另外，表示感觉的动词 see， hear， feel， watch， notice， observe和have， let， make后的宾语可接不带to的不定式（help后不定式可带to也可不带to）

29） I often heard him that his family was well descended.

［A］ said［B］ say［C］ to say［D］ to be said

30） We must have a person them build the house.

［A］ see［B］ to see［C］ will see［D］ shall see

31） You would become irritated ［A］ if you watched ［B］ the correspondence to pile up ［C］ on your desk day by day ［D］ .

4. 表示心理状态的动词像consider， declare， find， prove， think， know ， believe， discover， feel（=think）， imagine， judge， pretend， suppose， understand等词的宾语补足语不定式一般是to be（或动词的完成时态）

32） “You've been taking a lot of nice photographs.”“Thanks. I'm considering a professional photographer.”

［A］ becoming［B］ about become［C］ to become［D］ over becoming

而且，在consider， declare， find， prove， think等动词后的to be 是可以省去的。如： She considered me a scholar. / They found him gulty.

七、不定式的完成式、进行式和完成进行式：这三类在考研题中出现的频率很高，要特别注意不定式的这三种形式

1. 如果不定式所表示的动作与主要谓语所表示的动作（状态）同时（或几乎同时）发生或发生在主要谓语之后，那么用不定式的一般形式

He received a warm welcome from the Australians and from his family who had flown there to meet him.

In 1967， he arrived back in England， where a quarter of a million people were waiting to welcome him.

After all， eighty was a special birthday， another decade lived or endured just as you chose to look at it.

Now suddenly she began to sob， holding herself in as if weeping were a disgrace.

2. 如果不定式所表示的动作（状态）发生在主要谓语动词或特定的某时间之前，那么不定式就要用其完成式

She feels relaxed to have finished writing her thesis before the deadline.

33） The Vikings are believed America.

［A］ to have discovered［B］ in discovering［C］ to discover［D］ to have been discovered

34） The students were to at the auditorium before 1：30 pm， but the lecture was cancelled at the last minute.

［A］ assembled ［B］ have assembled ［C］ assembling ［D］ be assembled

35） He was to the new ambassador， but he fell ill.

［A］ having telephoned［B］ have telephoned［C］ has telephoned［D］ telephoning

3. 不定式进行式表示主要谓语动词所表示的动作（情况）发生时，不定式所表示的动作正在发生

When he came in， I happened to be doing my experiment in the lab.

Why do you stand here？ You are supposed to be working in the workshop.
