相信你一定可以成功的 用英语怎么说

I believe you can do it.（can，可以）
I believe you will succeed.（will，绝对）
以上两个是“〔我〕相信你一定可以成功的”

Believe that you can do it.
Believe that you will succeed.
这两个是“〔你要〕相信你〔自己〕一定可以成功的”

二楼的好，应该用make it

I believe you can make it！

I believe you will be able to successfully

I am sure you will make it (to succeed).
