Iwant to call him first,I don't want to surprised him.改错

I can't find him in his office.He may be in the reading room.
注意：may be 和maybe的区别。
I want to call him first,I don't want to surprise him.
注意： want to +动词原形。
What will the weather be like tomorrow?
注意：介词的用途。

I want to call him up first,I don't want to surprise him.
不知道有没有改对，错了不关我的事哦！
What the weather will be tomorrow?
