              動詞do在句中的作用可以概述為四句十二字:""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:

              The old man does an hour of sport every day.She did her homework at home last night.

              Mother was doing the cooking when I reached home.Have you done the exercises yet?

              2、"行動;工作;進展;足夠"。如:

              Kate does very well in her Chinese.How do you do?Well done! That 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在時和一般過去時兩種時態的否定句和疑問句中。如:

              They don't have any tickets for tonight's concert.Kate stayed at home last night, didn't she?

              How many books does the library have?She 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:

              Tom 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、強調句和倒裝句中,以加強語氣。如:

              Do be careful. Don't tell a lie.He did come. -You often go to the park. -So we do.
