中考網(wǎng)整理了關(guān)于2021年中考英語知識(shí)點(diǎn)之動(dòng)詞do在句中的作用,希望對(duì)同學(xué)們有所幫助,僅供參考。
動(dòng)詞do在句中的作用可以概述為四句十二字:"做"實(shí)義,助動(dòng)詞,替前文,強(qiáng)語氣。
作用一:實(shí)義do
do作實(shí)義動(dòng)詞時(shí),有do, does, did, done, doing五種形式,還有及物、不及物之分。如:
1. vt. "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.
、蹾ave you done the exercises yet?
2. vi. "行動(dòng);工作;進(jìn)展;足夠"。如:
①Kate does very well in her Chinese.
、贖ow do you do?
③Well done!
、躎hat will do.
作用二:助動(dòng)do
do作助動(dòng)詞時(shí),只有do, does, did三種形式,無詞義,限用于含行為動(dòng)詞的一般現(xiàn)在時(shí)和一般過去時(shí)兩種時(shí)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(dòng)詞的重復(fù),使語言簡(jiǎn)練,常以do, does, did替代前文所用的行為動(dòng)詞。如:
、賂om runs much faster than you do.
②-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(qiáng)調(diào)句和倒裝句中,以加強(qiáng)語氣。如:
、貲o be careful.
、贒on't tell a lie.
、跦e did come.
④-You often go to the park.
-So we do.
