题目

Mr Green stood up in defence of the 16-year old boy,saying that he was not the one___
A.blamed
B.to blame
已知知识点：sb be balmed = sb be to balme,为什么在A、B中只有B正确,而不能选A?
既然后半句前面有was，也就是be，那为什么后面接不能按照“sb be balmed = sb be to balme”用blamed？

答案

题干中的was 跟 要填的blame 没有任何关系
它对应的是the one
划线部分填的是后置定语
要么是the one to blame 要么是the one to be blamed,不能直接blamed.
一楼解释是错的.
二楼是对的 但是太绕了 说的不清晰
