用英语讲 不试不知道，要试了才知道

You never know what you can do before you do it.

You never know what can do till you try .

You will never know until you try it.

楼上的怎么把 用英语讲 也给翻译了？？？！！！

Please speak in English and you will get what you never expect till you try it.

把“用英语讲”也翻译了的，恐怕是直接从网上翻译的吧！很不准确。

个人认为是这样说：

You will never know what you can do until you try.
