while用于进行时态的问题
1.while i was running along,a dog ran across the road.
2.last night my father was reading while my mother was sewing.
while前后的时态怎么 确定.第一句只有while 后面的从句才用的进行式,主句则用的一般过去时,而第二句主从句都是用的进行式?
是跟延续性还算短暂性动词相关吗?但是还有人 read 也是用的一般过去时哦!

while:同时,当...时.
它可连接两个进行时的句子,也可只跟一个.
连接两个进行时,表明那两个动作并列发生的,互不相干,
while后接延续性动作词,而when则得后跟短暂性动词.
while 当...的时候
后面必须接延续性动词
用于过去进行时
例:He was writing while I was reading.
while在此是与此同时的意思.此句为对照.
