  【重点语法】

  动词不定式

  动词不定式的基本结构为“to+动词原形 ”(有时可不加to)。在句中除不能充当谓语外,其他成分都可充当,如:主语、表语、宾语、状语、宾语补足语、定语等。在八上已讲过作宾语的用法。在此主要讲作宾语补足语和状语的用法。

  (1) 作宾语补足语。

  动词不定式作宾语补足语,放在宾语的后面,表示宾语是什么或怎么样。有to do 和 to be 两种形式。

  The doctor advised him to take a good rest.

  I find English to be very easy.

  提示:在ask, tell, want, would like, advise, invite, teach,等动词或短语之后,常接带to的不定式做宾语补足语。

  We asked him to sing a pop song at the party.

  ① 动词不定式作宾语补足语时,不定式符号to在使役动词(have, make, let)、感官动词(feel, hear, watch, see, notice等)的后面时要省略。但他们变为被动语态时,不定式符号to不能省略。

  The boss made the workers work over ten hours a day in the past.

  = The workers were made to work over ten hours a day by the boss in the past.

  ② 动词help接不定式做宾语补足语时,不定式符号to可省略也可不省略。

  He often comes to help us (to) do some farm work.

  (2)作状语

  ① 表目的:表目的时,不定式可放在句子的前面也可放在句子的末尾。但在句子前面时,不定式常与句子用逗号隔开;而在句子末尾时一般不用逗号隔开。

  To get there on time, we set out at five in the morning.

  He goes there to enjoy the fresh air.

  ② 表结果:不定式做结果状语,一般位于句子末尾。

  I went to the classroom, to discover it empty.

  动词短语

  1.动词短语是指动词和介词或副词等搭配而构成的短语。

  2.动词短语主要有以下四种构成形式:

  • =Please pick the pen up.

  • Can you pick it up.

  • 3)动词+名词+介词
