动词不定式归纳定义:不定式的to和介词to需要被区分开,不定式的to后接动词原形,介词to后接名词、代词或动名词。
不定式作动词宾语He decided to invite all of his classmates to attend the holiday at the beach. 不定式作宾语He promised not to tell anyone about it.如果宾语有自己的补语,则常用it作形式宾语,而把真正作宾语的不定式放在后面放在后面,常带有形式宾语的动词有:believe. Consider. Feel. Find. Know. Make . regard例:we think it important to obey the laws. √we think to obey the laws is important. ×I know it impossible to finish so much homework in a day.不定式作介词宾语当介词but、except、besides前面有行为动词do及其各种形式时,介词后面的不定式可以省略to,否则不省略。
What do you like to do besides play football?We have no choice but to wait.个别介词可以用“疑问词+不定式”作宾语The boy has him own idea of how to finish it.不定式起形容词作用作定语不定式作定语用来修饰名词或代词,置于它所修饰的词后,而且放在其他后置定语的后面。
同时与它所修饰的名词或代词形成逻辑上的动宾关系或主谓关系。
He always has a lot of meetings to attend. 不定式to attend 和名词meetings 形成动宾关系The next train to arrive was from Seattle. To arrive 和train形成主谓关系Do you have anything interesting to read?如果作定语用的不定式是不及物动词,就要加上介词,使被修饰的这个词成为这个介词的逻辑宾语。

非谓语动词没有人称和数的变化。

动词不定式的形式:第一部分动词不定式的时态一、动词不定式的时态:动词不定式不能在句中作谓语,尽管它本身有时态的变化,但是却不能靠自身的变化形式表示动作发生的具体时间。
动词不定式发生的时间,一般只能根据谓语动词的时间,产生相对的先后时间关系。
1.不定式的一般式,表示不定式的动作与谓语动词动作几乎同时发生,或在谓语动作之后发生,或者不强调不定式动作的时间性。
但不定式表原因时,往往先于谓语动作之前发生。
如:The news will not fail to surprise him.这个消息将不会不使他大吃一惊的。
(不定式动作在将来和谓语动作同时发生)I helped to repair the car.我帮助修理汽车。
(不定式动作在过去与谓语动作同时发生)He didn't know where to go.他不知道该去哪儿。
(不定式稍晚于谓语动作)Tell your brother not to come tomorrow.告诉你哥哥明天不要来。
(不定式晚于谓语动作)判断:He decided to sell his car.I tried to go to school in time.I hope to see you soon不定式表示谓语动作的原因时,往往发生在谓语动作之前。
如:I am very happy to see you here.She seemed surprised to meet us.(先是遇见我们,她然后很吃惊)2.不定式的完成式,通常表示动作发生在谓语动词之前。
