答
When your homework is finished,you may go out to play.为什么用 is finished?涉及到哪些语法?
答:主从复合句.When引导一个时间状语从句.在这个从句中,主语是your homework,它与finish(完成)之间是被动的关系,所能用了助动词be的形式之一is加上及物动词finish的过去分词.涉及到了句子结构,被动语态.在时间和条件状语从句中用现在时表示将来,所以从句中用is finished,而不用will be finished.涉及到了条件和时间状语从句的时态.因为主语是不可数名词you homework,作单数可数名词看待,涉及了主谓一致.
译:作业完成你就可以出去玩了.
