【練習(xí)】

1. It’s said that the Olympic Games _____(hold) ?in London in 2012 will cover more events than any other Olympics did.（填空練習(xí)）

答案：to be held

解析：hold與the Olympic Games之間是被動關(guān)系,且2012奧運(yùn)會尚未舉辦,應(yīng)用不定式表將來。

2. ??I listened to the wind, ______ that he would not cometonight.

A. thinking ? ?B. to think ? ?C. thought ? ?D. being thinking

答案：?A

解析：?分詞作伴隨狀語.如填C, 前面應(yīng)有and.不定式表目的或結(jié)果,句子意思不通.D 為不正確的表達(dá).

3.?The boy lay on his back, his teeth???______and his glaring eyes??______.

；looked ? ? ? ；looking??

g；looked ? ? g；looking

答案：?B

解析：獨(dú)立主格結(jié)構(gòu)在句中作伴隨狀語, teeth 與set兩個詞之間含有邏輯上的被動關(guān)系,所以用過去分詞；look這一動作是eyes所發(fā)出,所以用looking。

4.?All the thing??______，his proposal is of greater value than yours.

ered?? ering?? consider?? er

答案： ?A

解析：?獨(dú)立主格結(jié)構(gòu)在句中作狀語,因為things與consider之間含有被動關(guān)系,所以用過去分詞。

5.?? ______who she was, she said she was Mr.Johnson's friend.

A.Asking?? B.Asked?? C.To be asked?? D.When asking

答案：??B

解析：分詞短語作狀語,因為ask與句子的主語（she）之間有被動關(guān)系,所以用過去分詞。

6.?A doctor can expect _____ (call) at any hour of the day or night.?（填空練習(xí)）

答案：?to be called

解析：?expect后跟不定式作賓語,call與doctor之間是被動關(guān)系。

【小知識】動詞不定式的基本用法

（1）作賓語：
①作及物動詞的賓語，如：She wishes to be a musician.
②作某些形容詞的賓語：可以有動詞不定式為賓語的形容詞一般有g(shù)lad， sorry，afraid，pleased， determined， willing，eager， anxious， ready， sure等，如：I am determined to give up smoking.
③動詞不定式一般不作介詞的賓語，但動詞不定式之前如有疑問詞時，就可作介詞的賓語，如：Can you give us some advice on what to do next?

（2）作賓語補(bǔ)足語，如：Tell the children not to play on the street. 如果句中的謂語動詞為see， hear，watch， notice， have，make， let等，作賓語補(bǔ)足語的動詞不定式須將to省去，如：I saw a little girl run across the street. ?
