since then he - - - - - -（再也没去过那儿了）

Since then he __(work) at this factory. since then he - - - - - -（再也没去过那儿了） Since he asks you,then you'll tell him why.then加着有没有毛病啊 since when ,since then的区别（在线等）he came back from abroad in 1998,since when,he has been doing his business.这一句中为什么用since when 却不能用since then , But then /Before then / Since then/ Until 翻译：ever since then ever since then since then,he hasn't smoked no longer.改错,在线等!加分! Since then he played in more than twenty films.这句话哪错了 Since then he was been doing the work.怎么译?用的是什么时态? Since then he played in more than twenty films.这句话哪错了 He left home as a young man and (not see) since then 怎么变时态, he left home has a young man and (notsee) since then 怎么变时态 Since then,he -----(not be)able to walk any more.只要有Since then就用现在完成时吗，若是，麻烦举几个例子，谢喽 since then可以说成 since that time 从那以后是from then还是since then? since then 是啥意思? ----------------you----------------(know)him since then
