have you...一般用于現(xiàn)在完成時(shí)態(tài)的謂語(yǔ)
are you是現(xiàn)在進(jìn)行時(shí)的謂語(yǔ)
do you是一般現(xiàn)在時(shí)的謂語(yǔ)
have you后跟過去分詞(不要跟動(dòng)詞的過去式搞混)
My sister joined the party last year.改為現(xiàn)在完成時(shí)時(shí)
My sister has joined the party last year.這樣是錯(cuò)誤的.因?yàn)?join"是轉(zhuǎn)瞬即逝的,一瞬間完成的,要用延續(xù)性動(dòng)詞來代替"join"
My sister has been at the party for one year.
are you后面要跟動(dòng)名詞,直接加ing的我就不多說了,有些以y結(jié)尾的注意下,不是所有的都是去y加ing,當(dāng)y前面是開音節(jié)就應(yīng)該去y加ing,而以閉音節(jié)結(jié)尾時(shí)不必去y了.有些以重讀閉音節(jié)結(jié)尾的單詞要雙寫末尾字母加ing.
do you的話就比較好理解,跟動(dòng)詞原型拉~不過要注意主語(yǔ)哦
我個(gè)人認(rèn)為這里面現(xiàn)在完成時(shí)最重要.哈,寫了這么多不曉得對(duì)不...
