2012小升初英語語法知識(shí)要點(diǎn):動(dòng)詞不定式2(2)

2012-02-09 11:38:37     

  動(dòng)名詞與不定式

  1) 動(dòng)名詞與不定式的區(qū)別:

  動(dòng)名詞表達(dá)的是: 狀態(tài),性質(zhì),心境,抽象,經(jīng)常性,已發(fā)生的

  不定式表達(dá)的是: 目的,結(jié)果,原因,具體,一次性,將發(fā)生的

  2) 接不定式或動(dòng)名詞,意義相同。

  3) 動(dòng)名詞與不定式語義不同的有11 組:

  stop to do stop doing

  forget to do forget doing

  remember to do remember doing

  cease to do cease doing

  try to do try doing

  go on to do go on doing

  afraid to do afraid doing

  interested to do interested doing

  mean to do mean doing

  regret to do regret doing

  begin/start to do begin/start doing

  特殊詞精講

  stop doing/to do

  stop to do 停止,中斷做某事后去做另一件事。

  stop doing 停止做某事。

  They stop to smoke a cigarette. 他們停下來,抽了根煙。

  I must stop smoking. 我必須戒煙了。

  典型例題

  She reached the top of the hill and stopped ___ on a big rock by the side of the path.

  A. to have rested B. resting  C. to rest D. rest

  答案:C。由題意可知,她到了山頂,停下來在一個(gè)路邊的大石頭上休息。因此,應(yīng)選擇"stop to do sth. 停下來去做另一件事"。而不僅僅是爬山動(dòng)作的終止,所以stop doing sth。不正確。

  stop doing/to do

  forget doing/to do

  forget to do 忘記要去做某事!(未做)

  forget doing 忘記做過某事! (已做)

  The light in the office is stil on. He forgot to turn it off. 辦公室的燈還在亮著,它忘記關(guān)了。(沒有做關(guān)燈的動(dòng)作)

  He forgot turning the light off. 他忘記他已經(jīng)關(guān)了燈了。( 已做過關(guān)燈的動(dòng)作)

  Don't forget to come tomorrow. 別忘了明天來。(to come動(dòng)作未做)

  典型例題

  ---- The light in the office is still on。

  ---- Oh, I forgot___.

  A. turning it off  B. turn it off  C. to turn it off  D. having turned it off

  答案:C。由the light is still on 可知燈亮著,即關(guān)燈的動(dòng)作沒有發(fā)生,因此用forget to do sth。

  而forget doing sth表示燈已經(jīng)關(guān)上了,而自己忘記了這一事實(shí)。此處不符合題意。
