Question

She is going to has a big birthday party.

Comments

？？？

Answer 1

你应该是要表达：她即将会举行一个盛大的生日派对。

真确的句子应该是：She is going to have a big birthday party. 

为什么用have：因为to之后要放原本字，has并不是原本字，have才是

Answer 2

句子 "She is going to has a big birthday party." 中有语法错误。正确的说法应该是：

"She is going to have a big birthday party."

“Going to” 后面应该接动词原形，所以 “has” 应该改成 “have”。
