After much effort, I eventually persuaded him to take my advice that he _______ immediately.
A. be operated onB. was operated onC. operate onD. should operate on

Answer 1

选 A
原因如下
advice 表示建议和意见的词比较特殊，固定句型都是：sb advice/suggest that ab (should) do sth. 某人建议某人（应该）做某事。 should 在这里可以省略，但是后面动词要用原形。
be operated on 是固定搭配，表示着手做……， should 在这里可用也可以省略，但是后面的动词一定要用原形，所以是 be operated on

Answer 2

A

省略了should
