1、专题十,非谓语动词,非谓语动词,1,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,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

2、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,(3)作宾语补足语 在“动词+

3、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。,(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

4、the animals. 他们的职责是照看动物。,2.“疑问词+不定式”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： not+to+动词原形。,如：The teacher told us not to swim in tha

5、t river. 老师告诉我们不要在那条河里游泳。,4.不带to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 r

6、ather(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.

9、eave,B,2,动名词,1.动名词的形式、特征 动名词由“动词原形+-ing”构成, 相当于名词。在句中作主语、表语、宾语、定语等。 2.动名词的用法 （1）作主语。单独作主语时，谓语动词用第三人称单数形式；如果并列的动名词(短语)作主语, 谓语动词用复数形式。如： Reading in bed is not good for your eyes. 在床上看书对你的眼睛不好。 Reading and writing take me a lot of time. 读书和写作花费了我许多时间。,注意: 在英语中动词是不能作主语的, 应用动名词或动词不定式。表示泛指意义的行为时, 多用动名词作主语

10、, 但表示具体的行为时, 必须用动词不定式, 此结构通常用it作形式主语, 真正的主语为动词不定式, 通常放后面。如：Getting up early is good for our health. 早起对我们的健康有好处。 Its easy to read this book. 读这本书很容易。 （2）作表语。动名词(短语)作表语可以转化为动名词(短语)作主语。如：His favorite sport is playing ping-pong.
