2020中考英语二轮复习语法第十二讲过去进行时资料(通用版)
展开过去进行时
一、意义:
1.表示过去某一时刻正在发生或进行的动作
2.表示过去某个阶段一直进行的动作
二、结构:
肯定:主语+be(was,were)+V-ing+其他
否定:主语+be(was,were)+not+V-ing+其他
一般疑问句:Be+主语+V-ing+其他?
Eg:I was reading a book at this time of yesterday(肯定)
I was not reading a book at this time yesterday.(否定)
Are you reading a book at this time yesterday?(一般疑问句)
Yes,I was. No,I wasn’t.
He was talking when the teacher came in.(肯定)
He wasn’t talking when the teacher came in.(否定)
Was he talking when the teacher came in?(一般疑问句)
Yes,he iwas. No,he wasn’t.
Tips:
肯定句变否定句,因为有be动词,直接在be动词后加not。
变一般疑问句,以为有be动词,be动词提前,注意第一人称变第二人称。
三、动词原形变动现在分词(V-ing)规则
1.直接在动词词尾加ing
2.以不发音的e结尾的,去e加ing
3.以重读闭音节结尾的辅元辅结构双写尾字母加ing
Eg:swim,run,sit,hit,get,put,let,
4.以ie结尾的,把ie变y加ing
Eg:lie(说谎),tie(系),die(死)
