2.I k____ a lot about China.
3."W____ is your pen ""It's in my pencil case."
4.The boy is b____ Betty and Kate.
【导学探究】：I don't know.我不知道。
know意为“知道，认识”，是实义动词。当谓语动词由实义动词充当时，否定句式不能直接在动词后加not，而要借助于助动词do或does来完成，并在其后加not，放在实义动词之前。当主语是第三人称单数（he,she,it)时，在实义动词前加does not构成否定句，其缩写为doesn't；当主语是第一人称，第二人称及复数主语时，实义动词前加do not构成否定句，其缩写形式为don't。如：
He doesn't know my name.他不知道我的名字。
I don't know the boy.我不认识那个男孩。
