专题十非谓语动词非谓语动词1动词不定式动词不定式 分析甘肃近3年中考真题可以看出，对非谓语动词的考查，主语侧重于不定式和动名词，也会涉及过去分词和现在分词。涉及题型广泛，考生需要判断与之相关联的动词的用法，有的动词与不定式搭配，有的则是动名词。还有的动词既可以和不定式搭配也可以和动名词搭配，但意思完全不同。1.1.不定式的用法不定式的用法动词不定式由“to+动词原形”构成，没有人称和数的变化。具体用法有：(1)作主语不定式作主语时，往往用形式主语it代替，作为句子真正的主语的动词不定式则被后置。如：Its necessary to learn a foreign language.学习一门外语很有必要。(2)作宾语动词不定式一般用在及物动词后作宾语。在think,find,make等动词后通常用it作形式宾语，而将不定式移至形容词之后，构成“主语+谓语+it(形式宾语)+宾补(形容词/名词)+不定式”结构。如：I hope to get there before dark.我希望天黑以前到那儿。I found it difficult to solve the problem.我发现解决这个问题很难。(it是形式宾语，不定式to solve the problem是真正的宾语，difficult是宾语补足语)常接动词不定式作宾语的动词常接动词不定式作宾语的动词agree同意afford负担得起forget忘记decide决定expect预期hope/wish希望want想要learn学习manage成功begin开始prepare准备promise承诺pretend假装plan计划refuse拒绝try尽力need需要fail失败(3)作宾语补足语在“动词+宾语+不定式”结构中，不定式作宾语补足语。如：My mother told me to study hard.妈妈告诉我要努力学习。ask要求encourage鼓励want想要advise建议tell告诉invite邀请expect期望force强迫allow允许help帮助teach教persuade说服(4)作状语常见的状语有目的状语、原因状语、结果状语等。如：Mr.Lee will go to Hangzhou to visit the West Lake.李先生将去杭州参观西湖。(作目的状语)(5)作定语动词不定式作定语时，放在被修饰的名词的后面，作后置定语。如：There are many ways to solve the problem.有许多方法能解决这个问题。(6)作表语Their duty is to look after the animals.他们的职责是照看动物。2.“疑问词疑问词+不定式不定式”结构结构 动词不定式可以和what,which,when,where,how等疑问词连用，构成不定式短语，在句中作主语、宾语、表语、宾语补足语等。如：When to go to Beijing hasnt been decided yet.什么时候去北京还没定下来。(作主语)I havent decided when to leave yet.我还没决定什么时候离开。(作宾语)3.动词不定式的否定形式：动词不定式的否定形式：not+to+动词原形。动词原形。如：The teacher told us not to swim in that river.老师告诉我们不要在那条河里游泳。4.不带不带to的动词不定式的动词不定式(1)使役动词和感官动词后要用不带to的动词不定式作宾补。但是，当上述动词变为被动语态时，其后的不定式必须加上to。如：We often hear her sing.我们经常听见她唱歌。后接省略to的不定式动词：五看：watch,see,observe,notice,look at三使：let,make,have二听：hear,listen to一感觉：feel(2)在would you please(你愿意吗),had better(最好),why not(为什么不),would rather(宁愿)等结构后，需用不带to的不定式。如：He said he would rather stay at home.他说他宁愿待在家里。(3)两个并列的带to的不定式由and或or连接时，第二个不定式符号常常省略。如：She has learned to read and write.她已经学会了读和写。考点小练1.I didnt hear you come in just now.Thats good.I tried the baby up.A.to wake B.not to wake
