        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.

          ②She 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.

         、贖ow 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:

         、賂hey don‘t have any tickets for tonight’s concert.

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

         、跦ow many books does the library have?

          ④She doesn’t do the washing in the evening.

          作用三:替代do

          為避免動詞的重復,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.

         、-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:

         、貲o be careful.

         、贒on’t tell a lie.

         、跦e did come.

         、-You often go to the park.

          -So we do.
