九大时态详解 - 过去进行时 下载本文

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:

① lie→lying ② die→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

Were you having breakfast at 8:00 this morning? 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:
