“我怎么做你才能相信我”用英语翻译

What can I do that you can believe me ?

What can I do to make you believe me?

What should I do that you can believe me ?
用should更为合适.

What will i do that you may believe me?
用will表示我将要做什么，你才能相信我，而用that连接是句型需要，我觉得应该用may，它强调的是“能”，怎么样才能？我将做什么，你才能相信我？

How can i make you believe/trust me?
How could you believe/trust me?
用HOW开头的听起来更加有味道

How can I convince you?
