I think she has many friends 变否定句:：

Question

我知道否定句是： I don't think she has many friends. 我想问一下为什么变否定句后has不变？

Answer 1

孩子，这涉及一个知识点 否定前置。在有宾语同句的句子中，主句谓语如果是think suppose guess 等表示主语想法或者是推断的动词，如果你想要对宾语同句进行否定，需要把not提前。
另外宾语同句的谓语的单三或非单三取决于宾语同句的主语，给你举个例子1.I do not think Tom is a student,2. Tom does not think Jim works hard.如果还不会继续问吧。希望能帮助到你
