释义：
know (that) 知道……
know 后面加上（that 主语+动词），表示“知道……的事实或情况”。与 know+名词唯一的不同就是所接的是从句而不是单词。
例句：
Please stop. I know that you're lying to me.
算了吧，我知道你在骗我。
My fingers are crossed. I know you really want that job.
我替你祈祷，我知道你很需要那份工作。
I don't know that we can afford a Harley.
我不知道能不能买得起那辆哈雷摩托车。
Do you know that there's no liquor in this house?
你知道家里没有酒了吗？
对话：
A: Tina was very sick after dinner.
缇娜在用完餐之后非常不舒服。
B: I don't know that the food made her sick.
不知道是不是因为食物的问题。
