同义句改写：He pretended that he didn't know the answer
He pretended ____ ____ know the answer
答
not to
希望我的回答能够帮到你,是not to 吗总觉得有点不对劲pretend 的用法是：1 + n./ pron.如 He pretended illness.2 + 宾语从句3 + to dopretend to do sth假装做某事不定式的否定是在to前加not 。即pretend not to do sth 假装没做某事所以，我的答案是绝对正确的。楼下说是being not也行吗？绝对不行，我是老师，没把握不会误导你。
