你好,同学,很高兴回答你的问题
正确答案：
What he said surprised the teacher.
或 What he said made the teacher surprised.
或 What he said shocked the teacher.
解析：上面三个句子都是主语从句,waht 引导的主语从句.另外,还可以写成
His words shocked the teacher.
His words surprised the teacher.
His words made the teacher surprised.
这三个句子是短语His words 作主语,其实His words = What he said
