七、考查非謂語動詞用作賓語補足語

原則上，所有的非謂語動詞形式均可用作賓語補足語，其區別是：不定式表未來，現在分詞表進行，過去分詞表完成和被動。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】答案選A。作with的賓語的補足語要用非謂語動詞，排除選項B和C；與謂語動作同時發生用現在分詞作賓語補足語，排除表示將來的不定式選項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】答案選D。賓語it與explain是被動關系，用過去分詞作賓補，have sth done意為“請人做某事”。

八、考查非謂語動詞的邏輯主語問題

按照英語習慣，非謂語動詞的邏輯主語應與句子一致，否則就應調整句子結構。如：

While watching television, _________. (全國卷III)

A. the door bell rang                                 B. the doorbell rings

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

【分析】答案選C。因為watching的邏輯主語一定是we，排除選項A和B；又因在hear后作賓語補足語的是省略了to的不定式，所以選項D中的rings是錯誤的。

九、考查非謂語動詞用作主語的問題

原則上說，動詞用作主語，只能是不定式或動名詞，不能是分詞形式。這類考題命題還往往用動詞原形作為干擾項進行考查，同學們做題需引起注意。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】答案選D。動名詞短語用作主語。

十、考查“(be +) 過去分詞+介詞”結構

有一類“be+過去分詞+介詞”結構，如be interested in, be worried about, be lost in, be dressed in 等，也往往是命題的熱點。如：

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

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

【分析】答案選 B。因表示“迷路于”是lose oneself in，題中沒有oneself, 所以the two students與lose是被動關系，應該用過去分詞作狀語。

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】答案選 A。由dress的賓語一定是人或oneself可知，dress與he是動賓關系，即he與dress是被動關系，要用過去分詞作狀語，Dressed in …=As he is dressed in …
