改错................

1.去掉in,every day前一般不加in.
2.do you know why?最好不要省略助动词do,即便在口语中.
3.becuse it is my wish that you be happy forever.

you must be happy in every day ---you must be happy every day

must happy every day.Do you know why?
不知道对不对哦.

you must be happy everyday, do you know why? because it is my wish...just like this "wish tree"..

everyday/every day 前面不加介词，wist应该是wish吧，愿望，心愿。

去掉in,every day前不加in.
