Do you have any idea____?
A.when she will arrive
B.when she arrives
C.how will she arrive
D.why hasn't she arrived
请分析下考点和解题思路
重点说下A和B又什么区别?
A
这是when引导的同位语从句,用陈述句语序,排除C,D.同位语从句中不存在什么一般现在时表将来,所以排除B
再问： 那什么情况用一般现在时表将来？另外这道题为什么要用将来时？
再答： when 在引导时间状语从句时用一般现在时表将来， 意为“当。。。。时候” 如： When he comes, I will tell him about it. 此句中的when , 意为“什么时候” 全句意为： 你知道他将什么时候回来吗?
