1、非谓语动词非谓语动词 期末复习期末复习 概概 述述 01 非谓语动词 英语中，动词具有两种形式：谓语形式和非谓语形式 1. 动词的谓语形式必须和主语在人称和数上保持一致，受主语的限定， 因此又被称为动词的限定形式。 2. 非谓语形式不受主语的限制，因此又被称为动词的非限定形式。 3. 确切地讲，非谓语动词实际上指动词的非谓语形式。 4. 非谓语动词没有时态、数、人称的变化 5. 动词的非谓语形式： （1）不定式：由to+动词原形构成，to为不定式符号，并无实际意义。 （2）动名词：由动词+ing构成。 不定式不定式 02 不定式不定式 不定式： to do do 否定形式： not to do

2、 not do 不定式做主语 To finish the work in ten minutes is very hard. 用形式主语it代替不定式作主语 It is very hard to finish the work in ten minutes. It is adj+(for sb) to do. want, hope, wish, like, begin, try, need, forget, agree, know, promise, teach, refuse, help, arrange, dare, decide, determine, fail, manage, off

3、er, prepare, continue, ask, mean, choose, expect等之后跟不定式。 例如：例如： （1）I want to improve my English grade. （2）用it做形式宾语，如： Mark found it important to study the situation in Russia. 不定式做宾语 want, wish, ask, tell, order, beg, permit, help, advise, persuade allow, prepare, cause, force, call on, wait for, in

4、vite等词后做 宾补。 例如： I invited her sisters to attend my party. 不定式做宾语补足语 否定形式 宾语、宾补的不定式否定一般会前置。 I want not to improve my English grade. I dont want to improve my English grade. I invited her sisters not to attend my party. I didnt invite her sisters to attend my party. He is the first to get here. 不定式做定

5、语 1、目的状语、目的状语 He worked day and night to get the money. To get the money, he worked day and night. 2、原因状语、原因状语（一般放在adj.之后） Im glad to see you. 3、结果状语、结果状语 (一般和only连用) I visited him only to find him out. 不定式做状语 不带to的不定式 1、不带to的不定式一般是跟在使役动词 make, let, have . 之后。例如： It makes me cry. 2、放在感官动词 see, watch

6、, look at, observe, notice, hear, listen to, feel之后的动词原形，就是不带to的不定式，强调 动作发生的事实。例如： He saw the thief steal a ladys cell phone. 动名词动名词 03 动名词 动名词 doing 否定式 not doing 动名词作主语 Reading aloud is very helpful. 用it做形式主语 It is no good/use doing It is a waste of time doing have trouble/a good time doing 例如： It
