  [英语语法手册]非限定动词 B

  动词不定式

  意义、形式和特征

  1)基本概念和形式动词不定式(infinitive)是一种非限定动词,由不定式符号to加动词原形所构成。动词不定式有动词的特征,同时也有名词、形容词和副词的特征。

  2)动词不定式的动词特征

  a)如果动词不定式是及物的,须有宾语。如:

  He wants to study Japanese.他想学习日语。(动词不定式to study后面有宾语Japanese)

  b)动词不定式可以被状语修饰。如:

  The rain continued to fall heavily.雨继续下得很大。(动词不定式to fall后面有状语heavily)

  动词不定式加宾语或状语构成动词不定式短语,如上二例中的to study Japanese和to fall heavily。

  3)动词不定式的非动词特征

  用法动词不定式具有名词、形容词和副词的特征,所以它在句子中可用作主语、表语、宾语、定语和状语。

  1)主语

  To lean out of the window is dangerous.把身子伸出窗外是危险的。

  To talk with him is a great pleasure.和他谈话是一件非常愉快的事。

  To die for the people is a glorious death! 为人民而死,虽死犹荣。

  动词不定式短语作主语时,往往放在谓语动词的后面,而在句首用引词“作语法上的主语。上述两句即可改为:

  It is a great pleasure to talk with him.

  It is a glorious death to die for the people.

  注意也常用“It is+形容词+动词不定式短语”这样的句型:

  It is necessary to make a plan for this course of study.必须订一个学习这门课程的计划。

  It is not difficult to learn a foreign if you spend time and effort on it. 小只要你花时间下功夫,学好一门外国语并不难。

  His only desire was to be useful to the country.他唯一的愿望是做一个对国家有用的人。

  3)宾语有些及物动词常用动词不定式作宾语。这些动词有want(想要),wish(想望),like(喜欢),decide(决定),help(帮助),pledge(保证),begin(开始),forget(忘记),learn(学习),ask(要求)等等。动词不定式一般不作介词的宾语。如:

  Learn to walk before you run.先学走后学跑。

  动词不定式也可以用来作某些形容词的宾语。这些形容词通常只有ready(准备好,愿意),eager(急于),anxious(急于)等,但为了学习上的方便,也可以包括able(能够),sure(一定),glad(高兴),sorry(难过),afraid(怕),free(随意),pleased(高兴),determined(决心),willing(愿意)等。如:

  I hurried to the post office,only to find it was closed.我匆忙赶到邮局,不料已经关门了。
