问题补充：
you know that I have a few friends in the class 换成 否定句怎么改
答案：
可以有两种,一个是否定主句,即
You don know that I have a few friends in the class.
你不知道,我在班级有几个朋友.
另一种是否定宾语从句,即
You know that I don have any friends in the class.
你知道,我在班级没有任何朋友.
======以下答案可供参考======
供参考答案1:
you don know that I have a few friends in the class
主要考点，know,believe think这些单词接宾语从句，否定式加在主句上
或you know that I have few friend in the class.
考虑用few表示否定意味
供参考答案2:
你好: You know that I haven few friends in the class.
翻译: 你知道 在班上我几乎没有什么朋友
