        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(qiáng)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.

          ③Mother was doing the cooking when I reached home.

         、蹾ave you done the exercises yet?

          2、“行動;工作;進(jìn)展;足夠”。如:

         、貹ate does very well in her Chinese.

         、贖ow do you do?

         、踂ell done!

          ④That 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?

         、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:

         、賂om 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(qiáng)調(diào)句和倒裝句中,以加強(qiáng)語氣。如:

          ①Do be careful.

          ②Don’t tell a lie.

         、跦e did come.

         、-You often go to the park.

          -So we do.
