七、考查非谓语动词用作宾语补足语

原则上，所有的非谓语动词形式均可用作宾语补足语，其区别是：不定式表未来，现在分词表进行，过去分词表完成和被动。如：

1. I couldn’t do my homework with all that noise_________. (北京卷)

A. going on               B. goes on                 C. went on                 D. to go on

【分析】答案选A。作with的宾语的补足语要用非谓语动词，排除选项B和C；与谓语动作同时发生用现在分词作宾语补足语，排除表示将来的不定式选项D。

2. You should understand the traffic rule by now. You’ve had it _________often enough (天津卷)

A. explaining              B. to explain            C. explain                 D. explained

【分析】答案选D。宾语it与explain是被动关系，用过去分词作宾补，have sth done意为“请人做某事”。

八、考查非谓语动词的逻辑主语问题

按照英语习惯，非谓语动词的逻辑主语应与句子一致，否则就应调整句子结构。如：

While watching television, _________. (全国卷III)

A. the door bell rang                                 B. the doorbell rings

C. we heard the doorbell ring                     D. we heard the doorbell rings

【分析】答案选C。因为watching的逻辑主语一定是we，排除选项A和B；又因在hear后作宾语补足语的是省略了to的不定式，所以选项D中的rings是错误的。

九、考查非谓语动词用作主语的问题

原则上说，动词用作主语，只能是不定式或动名词，不能是分词形式。这类考题命题还往往用动词原形作为干扰项进行考查，同学们做题需引起注意。如：

It’s necessary to be prepared for a job interview; _________the answers ready will be of great help. (北京卷)

A. To have had        B. Having had           C. Have                    D. Having

【分析】答案选D。动名词短语用作主语。

十、考查“(be +) 过去分词+介词”结构

有一类“be+过去分词+介词”结构，如be interested in, be worried about, be lost in, be dressed in 等，也往往是命题的热点。如：

1. _________ in the mountains for a week, the two students were finally saved by the local police. (江苏卷)

A. Having lost           B. Lost                   C. Being lost               D. Losing

【分析】答案选 B。因表示“迷路于”是lose oneself in，题中没有oneself, 所以the two students与lose是被动关系，应该用过去分词作状语。

2. _________ in a white uniform, he looks more like a cook than a doctor. (湖南卷)

A. Dressed               B. To dress              C. Dressing             D. Having dressed

【分析】答案选 A。由dress的宾语一定是人或oneself可知，dress与he是动宾关系，即he与dress是被动关系，要用过去分词作状语，Dressed in …=As he is dressed in …

十一、非谓语动词的综合考查

有时命题者会将多个知识点综合起来进行考查，如在考查被动式的同时兼考完成式，在考查不定式的同时兼考分词，等等。如：

1. I don’t want _________ like I’m speaking ill of anybody, but the manager’s plan is unfair. (天津卷)

A. to sound                B. to be sounded     C. sounding              D. to have sounded

【分析】答案选 A。表示“想要做某事”want后只能接to do，排除选项C；sound like中sound是系动词，属不及物动词，不能用于被动语态，排除选项B；sound 发生在want后，故不用完成式，排除选项D。

2. “Is Bob still performing?” “I’m afraid not. He is said _________ the stage already as he has become an official.” (江苏卷)

A. to have left             B. to leave                 C. to have been left        D. to be left

【分析】答案选 A。因he与leave是主动关系，不用被动式，排除选项C和D；由already可知，要用完成式。
