1、一般在動詞詞尾加上-ing ,E.g. jump
2、以不發(fā)音字母e結(jié)尾的動詞,先去e,再加-ing. E.g have write
3、.以重讀閉音節(jié)末尾只有一個輔音字母結(jié)尾的詞,它前面是單個元音字母時要先將詞尾的輔音字母雙寫,再加上-ing. E.g. sit put
其句式變換都在be上做文章。
E.g. He is buying a bike.
Is he buying a bike?
He isn’t buying a bike.
一般由look,listen,now, at this moment等時間狀語做標(biāo)志。
4、習(xí)慣進(jìn)行:表示長期的或重復(fù)性的動作,說話時動作未必正在進(jìn)行。
Mr. Green is writing another novel.
(說話時并未在寫,只處于寫作的狀態(tài)。)
She is learning piano under Mr. Smith.
5、表示漸變的動詞有:get, grow, become, turn, run, go, begin等。
The leaves are turning red.
It's getting warmer and warmer.
6、與always, constantly, forever 等詞連用,表示反復(fù)發(fā)生的動作或持續(xù)存在的狀態(tài),往往帶有說話人的主觀色彩。
You are always changing your mind.
典型例題
My dictionary ___, I have looked for it everywhere but still___ it.
A. has lost, don't find B. is missing, don't find C. has lost, haven't found D. is missing, haven't found.
答案D. 前句是一個仍在持續(xù)的狀態(tài),應(yīng)用進(jìn)行時,由于沒有找到,其影響仍然存在,應(yīng)用完成時,瞬間動詞用于否定式時可用于完成時。
