　　4. Jim was badly hurt, so he had to stop ______ (walk). (用所给单词的正确形式填空)(四川省)

　　Key： 1. A 2. C 3. C 4. walking

　　[简析]一些常见的动词后面接不定式和接动词的-ing形式的区别如下："stop to do sth"意为"停止正在做的事情去做另外一件事"，"stop doing sth"意为"停止正在做的事"："remember to do sth"意为"记住去做某事"(事还未做)，"remember doing sth"意为"记得做过某事"(事已做)："go on to do sth"意为"接着做某事"(做完一事，接着做另一事)，"go on doing sth"意为"继续做某事"(一事未做完接着往下做)："forget to do sth"意为"忘了做某事"(事还未做)，"forget doing sth"意为"忘了曾做过某事"(事已做)。

　　6. A woman saw it ______ when she was walking past.

　　A. happen B. happens C. happening D. to happen (黑龙江省)

　　Key： 5. B 6. A

　　[简析]在see， hear， watch， feel等感官动词后面可接不带to的不定式，也可接动词的-ing形式作宾语补足语，用不定式表示动作的全过程(动作已结束)，用动词的-ing形式表示动作正在进行(动作尚未结束)。

　　九、动词不定式的省略及其符号to的保留

　　1. Would you like to go to the cinema with us?

　　Yes, ______. What time are we going to meet?

　　A. I would B. I would like C. I like to D. I'd like to (浙江省)

　　2. Would you like to go for a picnic with us?

　　______. What time are we going to meet?

　　A. No, I can't B. Yes, I'm glad　C. Yes, I'd love to D. I'd like (大连市)

　　Keys： 1. D 2. C

　　[简析]在口语中，动词不定式中的动词或短语动词在上下文中重复出现时，第二个动词不定式可以省略，但是to不可省略。这种用法常见于"be glad to"，"would like (love) to"，"have to"等结构中。

　　十、动词不定式的被动式和其他形式

　　The new hospital ______ is near the factory.

　　A. build B. builds C. to build D. to be built (青海省)

　　Key： D

　　[简析]当不定式的逻辑主语是不定式所表示的动作的承受者(宾语)时，用动词不定式的被动式，即：to be +过去分词;如果不定式所表示的动作发生在谓语动词表示的动作之前，不定式用完成式，即：to have +过去分词;如果不定式表示的动作和谓语动词表示的动作同时发生，用不定式的进行式，即：to be +现在分词
