【讨论】几句习惯用语的意思?

You're not serious.

I know better that that.

Did you really?
来学习下


你是认真的吗
第二句没见过，孤陋寡闻感觉 i know better than that
你肯定？

You're not serious.
你不是当真的吧？
是下面这个句子的省略形式：You're not serious, are you?

I know better that that.
红色部分应该是“than”吧？
I know better than that.－－看语言环境。“我知道得更清楚。”或“我不相信。”

Did you really?
你真的（做某事）了吗？

很抱歉在第二句中敲错了than,这是几个习惯用语，中文意思是：
你一定在开玩笑。=You can't be serious.
我才不信呢！
真的吗？
