2017届高三英语一轮复习课件:非谓语动词综述
定义及构成 非谓语动词主要包括不定式动名词分词(现在分词和过去分词),.即动词的非谓语形式除了不能独立作谓语外,可以承担句子的任何成分 它有三种形式:不定式,分词(现在分词、过去分词),动名词 1.非谓语动词与谓语动词的相同点有: (1)如果是及物动词都可与宾语连用,例如: They built a garden. They suggested building a garden. (2)都可以被状语修饰: The suit fits him very well. The suit used to fit him very well. (3)都有主动与被动, “体”式(一般式;进行式;完成式)的变化。例如: He was punished by his parents.(谓语动词被动语态) He avoided being punished by his parents.(动名词的被动式) We have written the composition.(谓语动词的完成时) Having written the composition, we handed it in.(现在分词的完成式) (4)都可以有逻辑主语 They started the work at once.(谓语动词的逻辑主语) The boss ordered them to start the work.(动词不定式的逻辑主语) We are League members.(谓语动词的主语) We being League member, the work was well done. (现在分词的逻辑主语) 2、非谓语动词与谓语动词的不同点有: (1)非谓语动词可以有名词作用(如动词不定式和动名词),在句中做主语、宾语、表语。 (2)非谓语动词可以有形容词作用(如动词不定式和分词),在句中做定语、表语或宾语补足语。 (3)非谓语动词可以有副词作用(如动词不定式和分词),在句中作状语。 (4)谓语动词在句中作谓语,受主语的人称和数的限制;非谓语动词在句中不能单独作谓语,它不受主语的人称和数的限制。 (5)英语中不能单独做句子的谓语。 功能及用法 (一)动词不定式:(to)+do,具有名词、形容词、副词的特征. 否定式:not + (to) do (1)一般式:不定式的一般式所表示的动作与谓语动词动作同时发生或发生在谓语动词动作之后. 例如: Im glad to meet you. He seems to know a lot. We plan to pay a visit. He wants to be an artist. The patient asked to be operated on at once. The teacher ordered the work to be done. 2.不定式的句法功能: (1)作主语: 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,真正的主语不定式置于句后,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. 常用句式有:1、It+be+名词+to do。2、It takes sb.+some time+to do。3、It+be+形容词+of sb +to do。4、It+be+形容词+for sb.+to do。常用careless,,clever,good,foolish,honest,kind,lazy,nice,right,silly,stupid,wise,等表示赞扬或批评的形容词,不定式前的sb.可作其逻辑主语。(2)作表语: Her job is to clean the hall. He appears to have caught a cold. (3)作宾语:常与不定式做宾语连用的动词有:want, hope, wish, offer, fail, plan, learn, pretend, refuse, manage, help, agree, promise, prefer, 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,放在宾语补足语后面,例如: Marx
