关于when和while前后时态的题..
when和while的前后事态怎么用总是分不清楚 .以下是几道题..最好做完说说为什么用这个时态...比较笨
1 She (see)the police car while she (drive)to work
2 I (make) the dinner when the telephone (ring)
3 She (look) out of the window when she (see) the fire
4 The teacher (come) intu the room while we (play)a game
5 While I (take)my dog for a walk ,it (begin) to rain
一定要对啊 不然我更糊涂了...
