非謂語動詞的否定式考題分析

非謂語動詞的否定式通常是在非謂語動詞之前not、never。當前面有邏輯主語時，要放在邏輯主語與非謂語動詞之間。如：

1. Mrs. Smith warned her daughter ________ after drinking. (全國卷)

A. never to drive B. to never drive

C. never driving D. never drive

【分析】答案選A。由warn sb. to do sth. 可排除C和D；不定式to do的否定式應是not / never to do，排除B。

2. —I must apologize for ________ ahead of time. ?That’s all right. (全國卷)

A. letting you not know B. not letting you know

C. letting you know not D. letting not you know

【分析】答案選B。非謂語動詞letting的否定式是在其前面加not。

3. ________ the programme, they have to stay there for another two weeks. (廣東卷)

A. Not completing B. Not completed

C. Not having completed D. Having not completed

【分析】答案選C。非謂語動詞的否定式，要將not等放在非謂語動詞的前面，排除D；they與complete是主動關系，用現在分詞，排除B；“還沒有完成”，發(fā)生在“決定”之前，所以用現在分詞的完成式，排除A。

4. Victor apologized for ________ to inform me of the change in the plan. (上海卷)

A. his being not able B. him not to be able

C. his not being able D. him to be not able

【分析】答案選C。非謂語動詞的否定式是將not放在非謂語動詞之前，排除A和D；又因為作介詞for的賓語一定是動名詞，排除B；此處的not放在動名詞being之前，邏輯主語his之后(from www.網址未加載)。
