2020年長沙小升初備考資料:Do的作用

  動詞do在句中的作用可以概述為四句十二字:“做”實義,助動詞,替前文,強語氣。

  作用一:實義,動詞do

  do作實義動詞時,有do, does, did, done, doing五種形式,還有及物、不及物之分。如:

  1、“做;研究;整理;完成”。如:

 、賂he old man does an hour of sport every day.

 、赟he did her homework at home last night.

 、跰other was doing the cooking when I reached home.

  ④Have you done the exercises yet?

  2、“行動;工作;進展;足夠”。如:

 、貹ate does very well in her Chinese.

  ②How do you do?

 、踂ell done!

 、躎hat will do.

  作用二:助動do

  do作助動詞時,只有do, does, did三種形式,無詞義,限用于含行為動詞的一般現(xiàn)在時和一般過去時兩種時態(tài)的否定句和疑問句中。如:

  ①They don‘t have any tickets for tonight’s concert.

 、贙ate stayed at home last night, didn‘t she?

  ③How many books does the library have?

 、躍he doesn’t do the washing in the evening.

  作用三:替代do

  為避免動詞的重復(fù),使語言簡練,常以do, does, did替代前文所用的行為動詞。如:

  ①Tom runs much faster than you do.

 、-Lucy, can you get some more tea, please?

  -Sure. I‘ll do it right away.

 、-Who broke the cup?  -Mimi did.

  ③-I like bananas.

  -So does he.

  作用四:語氣do

  為突出感情色彩,do常用于祈使句、強調(diào)句和倒裝句中,以加強語氣。如:

  ①Do be careful.

 、贒on’t tell a lie.

 、跦e did come.

  ④-You often go to the park.

  -So we do.
