写一些what to do 和how to do it 的句子

这两个句型其实你可以死记
用来做选择题的
what不能加it
how一定要加it

它的意思为：What to do—去做什么 后可连加什么时候（回答something)；How to do it—怎么去做（回答You can …或You'd better …或其他）
e.g:-What to do at a.m 6:00? -Go to school.
e.g:-What's this? -It's a computer.
-How to do it?
-You can move the mouse and open the "help".
-Thank you.
-That's all right.
