九大时态详解过去进行时

五．过去进行时定义：表示过去某个时间点正在发生的事情

句型结构：主语+谓语动词+（宾语）

谓语动词：was/were +doing (动词ing形式)

*注意：进行时态的中出现的动词必须是持续性动词，而非短暂性动词。

动词ing形式的变化规则：

1.在词尾+ing，如play→playing；

2.当动词以重读闭音节结尾且结尾只有一个辅音的时候，双写末尾的辅音+ing，如run

→running；

3.当动词以辅音+e结尾时，去e+ing，如make→making

4.不规则变化：

①lie→lying

②die→dying

例1：We were having breakfast at 8:00 this morning.

例2: I was cleaning my bedroom at 7:00 last evening.

例3: Mary was waiting for the school bus then.

例4: You were listening to music when I saw you.

句型转换：

变为否定句：We were having breakfast at 8:00 this morning. (在be动词之后加

not)

weren’t

变为一般疑问句：Were you having breakfast at 8:00 this morning?

(把be动词提到句子最前面，其它不变)

回答： Yes, we were.

No, we weren’t.

特殊疑问句的变化规则：三步走，一换二代三提前

例1：We were having breakfast at 8:00 this morning.(对划线部分提问)

一换：换成一般疑问句

Were you having breakfast at 8:00 this morning?

二代：把划线部分用特殊疑问词代入

doing what

三提前：把特殊疑问词提前

What were you doing at 8:00 this morning?

拓展提高：

⑴由when引导的时间状语从句，从句用一般过去时，主句用过去进行时

主句：过去进行时引导词从句：一般过去时

注意：当when引导的从句与主句交换位置时，句子意思不变，如

You were listening to music when I saw you.

=When I saw you, you were listening to music.

She was reading a book when her mother came back home.

=When her mother came back home, she was reading a book.

⑵由while引导的时间状语从句，主句和从句都用过去进行时

主句：过去进行时引导词从句：过去进行时

=While my dad was watching TV, I was doing my homework.

Linda was cleaning her bedroom while her brother was playing outside.

=While her brother was playing outside, Linda was cleaning her bedroom.

注意：从句要紧跟着引导词。

练习二：请把下列句子改成特殊疑问句(写出变化步骤)
