A.will be handed out
B.are handed out
为什么应该选B而不选A`````
请各大高手赐教

“as soon as the papers______”
这一段是时间条件状语, 条件状语用一般现在时,后面的从句用将来时。所以选则B,倒过来看,你就明白了:
as soon as the papers______I'll go to see you

由as soon as 引导的条件从句,主句用将来时从句用一般现在时代替.

时间状语从句和条件状语从句的时态如果是一般将来时,根据语法要用一般现在时, 如; If you are free tomorrow, come to see me .(条件)
When he comes, please tell him the news.(时间)
As soon as you arrive in Beijing,write to me.(时间)

因为后面是时间状语从句,必须用一般现在时代替将来时。

这是一个语法问题,因为在条件从句中,要表示将来时,主句用将来是而从句要用一般现在时。如:if 从句:I will go to the park tomorrow if (as long as )it is funny.
