2023年中考英语知识点之其结构为be+现在分词

2023-03-29 11:33:32佚名

1、一般在动词词尾加上-ing ,E.g. jump

2、以不发音字母e结尾的动词,先去e,再加-ing. E.g have write

3、.以重读闭音节末尾只有一个辅音字母结尾的词,它前面是单个元音字母时要先将词尾的辅音字母双写,再加上-ing. E.g. sit put

其句式变换都在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等时间状语做标志。

4、习惯进行:表示长期的或重复性的动作,说话时动作未必正在进行。

Mr. Green is writing another novel.

(说话时并未在写,只处于写作的状态。)

She is learning piano under Mr. Smith.

5、表示渐变的动词有:get, grow, become, turn, run, go, begin等。

The leaves are turning red.

It's getting warmer and warmer.

6、与always, constantly, forever 等词连用,表示反复发生的动作或持续存在的状态,往往带有说话人的主观色彩。

You are always changing your mind.

典型例题

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. 前句是一个仍在持续的状态,应用进行时,由于没有找到,其影响仍然存在,应用完成时,瞬间动词用于否定式时可用于完成时。
