why to do to 打错了。是Why to want to cheat

why to do to 打错了。是Why to want to cheat 我的英语老师写了wh+to do sth 这个结构,这个结构中的“wh”是什么意思? 如何讲解wh-+to do结构 wh- to do sth =什么 on the apoint of和 be about to do ,be going to do ,be to do 区别?打错了,是on the point of to go to the zoo turn left when you come to the crossroads为什么要加to do?我打错了，是为什么要加to go？ be used to doing 与be used to do的区别是?be used to do的be是没有的 打错了！ 脑筋急转弯：1.Why do birds fly to south?2.There is four mistake in this centence.Can you find them打错了,应是Can you find them? What does want to do 改正：want打错了 是wants why not do还是why not to do?都把我弄蒙了 英语翻译晕 错了 完整的是这个 It takes less time to do a thing right than it does to explain why you did it wrong wh－＋to do结构－Why does she always ask you for help?-There is no one else ____,is there?A.who to turn to B.she can turn to我知道B是对的,但A.为什么不可以? 是Why not to do sth还是Why not do sth? 是why bot do sth.还是why not to do sth. 那个语法是why not to do Sth还是why not do Sth why not sb +do还是to do Why do you do this to me Do you need to do homework?why?
