题目内容：

单句改错We persuaded him to stay at home,but he didn't
She insisted in writing a letter to her husband at once.
Heinsisted that he hear someone in the next room
全部是有错误的，另外insisted 这个句子省略了should 所以hear 用原形是对的

优质解答

2楼的完全是放P
第一句We persuaded him to stay at home,but he didn't没错
第二局She insisted in writing a letter to her husband at once.
in 改成 on 坚持做某事是 insist on doing sth
第三题 也没错 因为 insist that 后面动词用原型 句型是虚拟语气!
insist that sb should do sth.should可省略
