下面个句中均有一处错误,找出并改正.
3.He plans taking a very long vacation.
4.Who are you going shopping?
5.--What time is he coming back?
--He is coming back next Sunday.
不需详细说出解题思路.
1.什么是不定式的复合结构？2.双宾语和复合宾语有什么区别？
第2个问题千万别照着语法书上的定义说，我就是看不懂才来问的。希望用自己的话说出对它们理解和是怎样区分它们的。

Answer 1

1 plans taking 改 plan to take
2 who are you going shopping?改 who are you going to go shopping
3 改 when will he come back?应该用将来时 what time 一般是问时刻
