面臨2017小學(xué),除了學(xué)好數(shù)學(xué)之外,小學(xué)英語(yǔ)也是至關(guān)重要,小孩子學(xué)習(xí)英語(yǔ),首先就要先學(xué)習(xí)英語(yǔ)單詞?墒,許多孩子都覺(jué)得,單詞的學(xué)習(xí)非常的枯燥乏味,對(duì)于英語(yǔ)單詞的學(xué)習(xí)就是找不到一個(gè)好的方法。其實(shí),只要掌握規(guī)律,找到方法,單詞記憶還是很容易的。下面列舉一些小方法,以供參考。
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(yǔ)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.
②She 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:
、貹ate 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(wú)詞義,限用于含行為動(dòng)詞的一般現(xiàn)在時(shí)和一般過(guò)去時(shí)兩種時(shí)態(tài)的否定句和疑問(wèn)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(yǔ)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.
、-I like bananas.-So does he.
作用四:語(yǔ)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(yǔ)氣。如:
①Do be careful.
、贒on't tell a lie.
③He did come.
、-You often go to the park.-So we do.
