2018英语专四语法解析汇总

  1. 非谓语动词的基本用法

  ·非谓语动词的否定形式:否定词not均加在非谓语动词或者非谓语动词短语的最前面。例如:

  Not being tall is not aserious disadvantage in life.

  ·非谓语动词的时态和语态。

  一般说来,动名词和现在分词的一般时表示该动作和主句的动作同时发生,完成时则表示该动作发生在主句动作之前;过去分词的一般时表示该动作发生在主句谓语动词之前,进行时表示该动作和主句动作同时发生;不定式的一般时表示该动作发生在主句动作之后,进行时表示该动作和主句动作同时发生,完成时则表示该动作发生在主句动作之前。

  动名词、现在分词和不定式的一般时均表示该动作与其逻辑主语之间为主动关系,如果两者之间是被动关系,则要使用相应的被动形式;过去分词表示该动作与其逻辑主语之间为被动关系。

  a)现在分词

  一般时:Do you see the man talking to the dean?

  一般被动式:You'll find the topic being discussed everywhere.

  完成时:Not having made adequate preparations,they failed.

  完成被动式:Having been adapted,the script seems perfect.

  一般时:Fight no battle unprepared.

  c)不定式

  2. 非谓语动词的主要区别

  ·不定式和动名词作句子的主语、宾语的区别:

  Learning from others is important.

  b)有些动词要求不定式作宾语,如:  afford,agree,aim,apply,arrange,cause,consent,dare,demand,desire,determine,endeavor,expect,fail,hesitate,learn,manage,offer,ought,plan,plot,prepare,presume,pretend,proceed,profess,refuse,resolve,strive,struggle,swear,threaten,tend,volunteer,undertake,wait,want等。

  d)在can't bear,like,hate,prefer等表示喜好的动词后,动名词表示一般倾向,不定式表示具体行为。例如:
