Question

{初二英语}关于进行时表将来（be going to do)

如上。
只能用be going to do表将来么？能用be doing么？
请您看这道题
My brother is (going hiking) for vacation.（对括号内部分提问）
____ your brother ____ for vacation?
答案是What's;doing
请问这个是将来时还是进行时？
如果问句是What's your brother going to do for vacation?那么应该括起来哪个词组或单词？

Answer 1

be going to do = will do

这是一般将来时

what's....doing可以用what will.....do来代替

是将来时，因为是问你他将要去做什么

应该括起来hiking 因为What's your brother going to do for vacation
已经有what's....going了少的是to do的部分
