J知识点1:非谓语动词的句法功能 成份 形式主语宾语表语定语状语宾语补足语不定式动名词 现在分词过去分词知识点2:不定式的形式及用法(以动词do 为例) 用法形式 主 动被 动与谓语动词动作的先后关系例句一般式to doto be done同时/之后The patient asked to be operated on at once.进行式to be doing/同时The boy pretended to be working hard.完成式to have doneto have been
8、done之前I happened to have seen the film.注意:变否定都是在非谓语形式前加not知识点3:动词不定式的句法功能1)主语:To finish the work in ten minutes is very hard.To lose your heart means failure. 动词不定式短语作主语时,常用it作形式主语,例如上面两句可用如下形式:It is very hard to finish the work in ten minutes.It means failure to lose your heart.2)表语:Her job is to c
9、lean the hall.He appears to have caught a cold.批注:复习系表结构,系动词的用法。3)宾语:下列动词只能接不定式作(直接)宾语:hope, wish, want, ask, help, refuse, learn, demand, care, choose, arrange, expect, decide, agree, plan, promise, offer,manage, pretend, prepare, elect, fail, long, determine,desire等。这里可以借助几句口诀来帮助记忆:决心学会想希望,拒绝设法愿假装
10、,主动答应选计划,同意请求帮一帮。(在下划线上填写对应单词) 答案:determine/decide,learn,want,hope/wish/expect,refuse,manage,care,pretend,offer,promise,choose,plan, agree, beg, help.不定式一般不做介词的宾语,但是可以放在介词but/except之后做宾语。如果介词之前有行为动词do的各种形式,那么这些介词后的不定式不带to;否则就要带to。即所谓的“前有do, 后无to”。I have no choice but to stay here.I can do nothing bu
11、t stay here. 下列固定搭配中,也省略不定式to.cant choose butcant help but do sth can do nothing but it作形式宾语如果不定式(宾语)后面有宾语补足语,则用it作形式宾语,真正的宾语(不定式)后置,常用的动词有(consider, think, make, find, believe, count, declare, fancy, feel, guess, imagine, judge, prove, see, show, suppose, understand, take等)。批注:这里高考常考的动词有:consider,
12、make, find, feel, see, suppose, take 等。例如:We consider it our duty to support good leaders.The new method makes it possible to complete the task faster.4)作宾语补足语:下列动词之后用省略to的不定式作宾语补足语,用一句口诀来记忆:“五看三使两听一感觉”(请学生在下划线上填写对应单词) 答案:see, look at, watch, notice, observe/ make, let, have/ listen to, hear/ feel 批
13、注:变成被动结构时,不定式“to” 要还原。5) 定语:下列情况下一般用动词不定式做后置定语:不定式表将来I have a meeting to attend this afternoon.用来修饰被序数词、最高级限定的中心词。She was the first woman to win the gold medal in the Olympic Games.The best way to earn respect was to study hard and achieve high grades.用于修饰的词是抽象名词时,常见的有:ability, chance, idea, fact, e
14、xcuse, promise, answer, reply, attempt, belief, way, reason, moment, time等,这些名词经常被no, all, any等修饰。I had no ability to read and write English when I was five years old. 下列情况下,不定式之后要有相应的介词:作定语的不定式是不及物动词。There is nothing to worry about.不定式修饰的名词或代词是不定式动作的地点、工具等。Please give me a knife to cut with.如果不定式修饰
15、place, way, 可以省略介词。He has no place to live.This is the best way to work out this problem.批注:这里是否需要介词以及需要什么介词,可以引导学生把不定式短语倒过来,与其所修饰的名词或代词构成一个动宾短语就很容易判定了。当作定语的不定式所修饰的名词或代词是不定式动作的承受者时,不定式既可以用主动语态,也可用被动语态,但其含义有所不同。试比较:Have you got anything to send?(你有什么东西要寄吗?不定式to send的动作执行者是“你”)Have you got anything to
16、 be sent?(你有什么要寄的东西吗?不定式to be sent的动作执行者是“我”或“别人”)例1:I will go to New York next week. Do you have anything _ to your wife?A. bring B. to bring C. to be brought D. brought6)状语:目的He worked day and night to get the money.不定式做状语表示目的,可以用in order to, so as to 来替换,但是so as to不能用于句首。注意不定式放句首时,逻辑主语与句子主语要一致:判断
17、对错:To save money, every means has been tried. ( )To save money, he has tried every means. ( )批注:不定式位于句首时,句子的前后逻辑主语要保持一致。结果He arrived late to find the train gone.I visited him only to find him out.批注:only to do sth、turn out to be 通常表示的是意料之外的结果。原因:不定式与表示喜怒哀乐的形容词连用,一般表示原因They were very sad to hear the
18、news.程度:不定式与tooto 和enough连用Its too dark for us to see anything.The question is simple enough for him to answer.二、同步例题分析知识点1:非谓语动词的句法功能例1: _ in the early 20th century, the school keeps on inspiring childrens love of art.A.To found B. Founding C. Founded D. Having founded例2: _ the course very difficul
19、t, she decided to move to a lower level.(2013安徽)A. FindB. FindingC. To findD. Found批注:首先要审题,看清题目考察的是谓语动词还是非谓语动词,然后再详细分析题目考察要点。知识点2:不定式的形式及用法例1:Volunteering gives you a chance _ lives, including your own.(2013 北京)A. changeB. changingC. changedD. to change例2:_ warm at night, I would fill the woodstove
20、, then set my alarm clock for midnights so I could refill it.A. Staying B. Stayed C. To stay D.
