非谓语动词(一)动词不定式用法动词不定式没有人称和数的变化,在句中不能独立作谓语。

但动词不定式具有名词、形容词和副词特征,在句中可以作主语、宾语、宾语补足语、定语、表语和状语等多种成分。

另外,动词不定式具有动词特点,可以有自己的宾语和状语,组成动词不定式短语。

动词不定式的肯定形式是to+do;其否定形式是not to+do。

下面以动词不定式在句中的作用来予以详细说明。

1.作主语可以直接作主语。

如:To see is to believe.但在英语中,常用it作形式主语,真正的主语即动词不定式放在后面。

如:It's wrong to play tricks on other people.It's our duty to keep our environment clean and tidy.点击规律:动词不定式在句中作主语时,常放在It is +adj.(形容词)+to do sth.或It is +n.(名词)+to do sth.句型中,it仅作形式主语。

It is + 形容词+for sb. to do sthIt is + 形容词+ of sb. to do sth.It takes / took sb. some time to do sth2.作宾语a.want,decide ,agree等动词后面跟并且只能跟不定式。

如:We agreed to start early.She wants to be a doctor.b.love,like ,begin,start,hate ,prefer等词后面可以接不定式。

点击规律:上述动词后面除接不定式外,还可以接动名词,意思无很大区别。

提示板:like doing指经常性动作,而like to do指一次性的动作。

如:I like swimming,but I don't like to swim now.我喜欢游泳,但我现在不想游。

c.stop,forget,remember,go on ,try等词或短语后面可以接不定式。

点击规律:上述动词后面接不定式和接动名词意思大不相同。

提示板:1)stop to do sth.:停止一件事,去做另一件事。

stop doing sth.:停止正在做的事。

例句:When the teacher came in,the students stopped talking;when he came out,the students stopped to talk.当老师走进来时,学生们停止说话;当老师走出去时,学生们又开始说话。

2)思考:forget,remember,go on,try等词或短语后面接不定式和动名词用法有何区别?d.在find/feel+it+adj.+to do sth.句型中,it是形式宾语,真正的宾语是后面的动词不定式。

如:The man downstairs found it difficult to get to sleep.I feel it easy to recite the text.点击规律:某些动词或短语后面既可以接动词不定式作宾语,又可接动名词作宾语,二者用法上的区别可以通过造句子加以区分,如上面stop例句。

3.作宾语补足语a.tell,ask,want,order,teach,invite,warn,wish,help,get,wish,help等词后面常接不定式作宾补。

如:I tell him not to go there by bus .Edison's mother taught him to read and write.b.let,make,have,see,hear,feel,watch,notice后面接不带to的不定式作宾补。

如:The boss makes them work 16 hours a day.I heard her sing in the next room.提示板:若变成被动语态,在上述结构中,不定式符号to要加上。

如:They are made to work 16 hours a day by the boss.She was heard to sing in the next room.4.作定语:放在被修饰的名词、代词后面例句:I have a lot of work to do.The doctor said he could do nothing to help the boy.点击规律:动词不定式若在句中作定语,常放在被修饰的名词、代词之后。

提示板:如果动词不定式和前面所修饰的词构成动宾关系,若动词是不及物动词,切记不要忘掉介词。

如:I have a small bedroom to live in.Have you got some pens to write with?5.表语:放在连系动词be后面例句:His wish is to become a scientist.The first important thing is to save the soldiers' lives.当务之急是抢救战士们的生命。

点击规律:动词不定式在句中作表语时,通常对连系动词前面的名词进行诠释说明。

6.作状语a.目的状语:放在go,come,use,live,in order等词后面。

如:I come to see you.He runs fast in order to get there in time.b.原因状语:放在sorry,glad,surprised,disappointed,excited等词后面。

如:I am glad to see you here.I am sorry to trouble you.c.作结果状语。

如:Some of the apples are hard to reach.The room is large enough to hold 1000 people.7.与what,who,whose,when,where,how等疑问词连用,作宾语、宾语补足语、主语等。
