一、动词不定式与-ING分词的区别
(一)作宾语时，-ING分词表示抽象的、一般性或习惯性的和连续性的动作，而不定式则表示某次具体动作，特别是将来的动作
| I like playing football. | I would like to play football this afternoon. |
|---|
- The school cannot tolerate _____ on exams.
［A］ cheating
［B］ to cheat
［C］ be cheated
［D］ being cheated - News of success keeps _____ in.
［A］ pouring
［B］ to pour
［C］ poured
［D］ to be pouring - Long ［A］ before the dawn ［B］ of recorded ［C］ history, humans celebrated to harvest ［D］ their crops.
(二)作定语时，-ING表示正在进行的动作，用-ING的完成时表示动作的完成；不定式表示未来发生
- We were overjoyed at the news of China _____ another man-made satellite.
［A］ having launched
［B］ to have launched
［C］ to launch
［D］ launched - The applicants interviewing ［A］ are required to ［B］ bring all the necessary papers ［C］ two days later ［D］ .
- Sorghum(高梁) leaves ［A］ occasionally contain ［B］ enough hydrocyanic acid killing ［C］ livestock(牲畜) ［D］ .
(三)当谓语动词是进行时的时候，用不定式而不用-ING分词作宾语
| It's beginning to snow you. | It starts raining. |
|---|---|
| I'm considering how to go(where to go, what to do). | I considered emplying Mr.Wang but decided that Mr.Chen was more suited to the job. |
(四)在remember,forget等词后，如果跟-ING分词，表示-ING分词的动作发生在主要谓语之前；如果跟不定式则表示不定式的动作发生在主要谓语动作之后
| I remember telling her that last night. ("告 诉"发生在"记得"之前) | He remembered to tell her that when she came back. ("记得"发生在"告诉"之前) |
|---|---|
| I'm sorry I forgot to give you the message. (主 语动词表示的动作"忘记"发生在不定式表 示的动作"给带口信"之前) | Why! I have such a bad memory. I forgot giving the message last night. (-ING分词 表示的动作"给带口信"发生在谓语动词表 示的动作"忘记"之前) |
(五)stop, go on和leave off之后跟接动词不定式和-ING分词所表达的意义有所不同
They stopped (talking) to work. ［停下(其他动作)来工作］
They stopped working. ［停下工作(来干其他动作)］
Workers went on discussing the problem. ［工人继续讨论这一问题］
Workers went on to discuss the problem.［工人们停下来其他事，继续讨论这一问题］
He left off writing.［他停下写作(去干其他事)］
He left off to write.［他停下(其他事)来写作］
(六) ... used to后跟不定式和-ING分词，后跟不定式有两种情况：一种是used to是固定用法表示"过去经常干......"；另外一种情况是use的被动词态"be used"后跟不定式；后跟-ING分词的情况有一种，那就是当used to中的used是形容词时，to后跟名词或-ING分词

［A］ has worked
［B］ had worked
［C］ had been worked

［B］ get to
［C］ get over
［D］ get on with - Mr. Anderson used to jogging ［A］ in the crisp morning ［B］ air during ［C］ the winter months ［D］ , but now he has stopped.
(七)一般情况下，for后边跟接there to be,而of后边则跟接there being
- It is fairly common in Africa for there _____ an ensemble of expert musicians surrounded by others who join in by clapping, singing, or somehow adding to the totality of musical sound.
［A］ to be
［B］ being
［C］ to have been
［D］ having been
(八) be＋形容词后面要跟动词不定式作状语，而不用-ING
