when和while跟过去进行时还是过去式,怎么跟,两句互换怎么换,
关于when,while,
解题思路: 如下
解题过程:
由when、while引导的时间状语从句的时态:
主句(过去进行时)+when +从句(一般过去时)
主句(一般过去时)+when +从句(过去进行时)
主句(一般过去时)+while +从句(过去进行时)
主句(过去进行时)+while +从句(过去进行时)
①Mother __was cooking_(cook)supper when I __got____(get)home yesterday.
②Last Sunday I__met_(meet)Lin Hong when I __was walking__(walk)in the street .
③Father was cleaning (clean) his car while I was playing (play) computer games.
④Tom rushed (rush) into the house while his mother was reading (read).
总结:
动词为短暂性动词用一般过去时,动词为延续性动词则用过去进行时。
当从句的谓语动词时延续性动词时,既可以用when,也可以用while;当从句的谓语动词是短暂性动词时,只能用when。
最终答案:略
