Why don't you用法:
“Why don’t you+動(dòng)詞原形+…?”,在這個(gè)結(jié)構(gòu)中,為何why don't后面就得用到主語“you”呢?
原因在于“don't”的'實(shí)質(zhì):do not的縮寫,里面的do是個(gè)助動(dòng)詞,根據(jù)詞法原則,助動(dòng)詞幫助主動(dòng)詞構(gòu)成完整的謂語結(jié)構(gòu),而只有在“句子”中才會(huì)用到完整的謂語結(jié)構(gòu),英語中的句,必須有主語和謂語,主謂完整才叫句,所以用到了why don't,就得有主語you。如:
Why don't you have another try?為何不再試一次呢?
也可以認(rèn)為,why not +原形動(dòng)詞是簡(jiǎn)略形式,why don't you是完整形式,如果不想深入理解,就直接記住即可。
Why not go and have a look?=Why don't you go and have a look?您咋不去看看呢?
