She says she knows you 变成否定句 谢谢

Answer 1

She says she does not know you

She says 后面引导宾语从句，从句用否定表示否定句
英语没有She desn't says she knows you的说法，这种说法是中国人按自己习惯来写的。有人称这种为“中国式的英语”

She says she doesn't know you 。
我是英语教师，答案百分百对。

我们说的变否定句都是相对于主语，所以只要对谓语进行改变。
这里就改为：She doesn't say she knows you.

Answer 5

She desn't says she knows you或者She says she doesn't knows you
