了“虽然”就不能再用“但是”（,but,）但可以与,yet,或,still,连用。,2.though/although,意义相同，用法基本一样，前者通俗，口语化，后者正式多放主句的前面。,even if,even,though,I,ll go even if(though)it rains tomorrow.,即使明天下雨，我也要去。,even if,和,even

ifC.unless D.as though,A,B,while,是高考中的高频词，它既可引导时间状语从句，又可引导并列句，还可引导让步状语从句，表示“尽管”。,even if,等于,even though,，表示“即使、尽管”。,as though,等于,as if,，引导方式状语从句，表示“好像、似乎”。,问题,2,：,1.,He tried his best to solve the
