1.不用 "is stayed" 是因为桌椅呆在房间里,不是被动语态,而是主动语态.
V-LINK If someone or something stays in a particular state or situation,they continue to be in it.保持 (某种状态)
2.填comes,一般现在时,因为before my father comes back是一个从句.
before引导的时间状语从句表示主句动作发生在从句动作之前.从句不用否定的谓语形式.从句位于主句之后时,before有时译成“才;就”.还要注意主句和从句的时间关系.当主句用将来时,从句总是用现在时;从句用过去时,则主句多用过去完成时,以此来体现动作发生的先后顺序

i have to finish my homework这是将来时态?

如果主句是一般现在时,从句当然也是啊。 一般来说,before从句用的是现在时的话,主句是将来时。可以再看看下面的参考资料: 当after 和before引导时间状语从句时,主句的谓语动词常用一般将来时。 如:He will finish his homework before his father comes back. It will be a long time before Tom comes back from abroad. 英语中,从句用一般现在时来代替一般将来时的情况还有,在条件状语从句、时间状语从句和让步状语从句中都是属于这种情况。否则,要用将来时。 再如 :I won't go if it rains tomorrow.

nothing but one desk and six chairs are in the room,不能用is,因为是复数,而且桌子和椅子在屋子里这件事还没有结束,所以不能用过去时
