选几啊为什么

we______ on the playgroud when it began to rain yesterday afternoon A run B ran C are running D weA run B ran C are running D were running选几啊为什么
选D,因为前后时态要一致,began是过去式,所以要选有过去式的选项,而跑步是延续性动作,依题意得只可以选D,

D
when 当一个动词发生时另一个动作正在进行( 根据BEGAN 可知是过去进行时)
加油!不明白再问!如果帮到你,请采纳,谢谢!

D were running
首先yesterday是在描述昨天发生的事所以用过去时,句子是在描述下雨那一刻发生的事所以要用进行时,加起来就是过去进行时。

D were running

选D be doing...when...正在做某事,突然......此处为过去时。
