非谓语动词的否定式考题分析非谓语动词的否定式通常是在非谓语动词之前not、never。

当前面有逻辑主语时，要放在逻辑主语与非谓语动词之间。

如：1.

Mrs.

Smith warned her daughter ________ after drinking.

(全国卷)A.

never to drive B.

to never driveC.

never driving D.

never drive【分析】答案选A。

由warn sb.

to do sth.

可排除C和D；不定式to do的否定式应是not / never to do，排除B。

2.

—I must apologize for ________ ahead of time.

–That’s all right.

(全国卷)A.

letting you not know B.

not letting you know C.

letting you know not D.

letting not you know【分析】答案选B。

非谓语动词letting的否定式是在其前面加not。

3.

________ the programme, they have to stay there for another two weeks.

(广东卷)A.

Not completing B.

Not completed C.

Not having completed D.

Having not completed【分析】答案选C。

非谓语动词的否定式，要将not等放在非谓语动词的前面，排除D；they与complete是主动关系，用现在分词，排除B；“还没有完成”，发生在“决定”之前，所以用现在分词的完成式，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】答案选C。

非谓语动词的否定式是将not放在非谓语动词之前，排除A和D；又因为作介词for的宾语一定是动名词，排除B；此处的not放在动名词being之前，逻辑主语his之后
