They were playing on the computer （）their teacher came in.A after B when C until D then这道题很简单我知道选B但是我同桌英语很差她不明白我想给她详细讲可是又不懂怎么讲吧教我吧

可以用排除法丫,从意思上a c d ,讲不过去阿,而且,when ,作为一个状语从句表示同时发生,即当老师进来上他们正在玩电脑再答：哎呀，错了，是伴随状语。。。
再问：不是伴随吧
再问：好吧你讲专业点
再问：就讲别的几个为什么不行那个我会解释
再答：嗯，疏忽，是时间状语从句
再答：嗯，第一个，after,若加上就是说，在老师进来之后他们在玩电脑
再答：貌似after ,之后，came in不太讲
再答：而且后两个意思分别为，直到，然后，放在句子中意思说不太过去
再答：还要一种办法
再答：就是，这几个词都是可做为时间状语从句
再答：但是，when表示主从句动作同时发生
再答： when ,after表示动作先后发生
再答： untill表示一个动作延续至第二个动作开始，用于肯定句时，主句需用延续性动词
再答：差不多这样了吧，也许有不太对的地方，包涵。我是这样理解的
再问：看你打字累就采纳你吧
再问：其实你讲和没讲都一样
再问：我这题做对没
