不及物动词加上个介词就可以有被动语态了吗?

一、使用被动语态的注意问题之一：不及物动词无被动语态.
eg:What will happen in 100 years.
The dinosaurs disappeared about 65 million years ago.---------(百度百科)
二、mug《英汉高阶英汉双解词典》（第四版增补版）中第四个词条,是及物动词
mug[Tn](Tn即及物动词的意思) attack and rob (sb) vinlently out of doors (户外)行凶抢劫（某人）
eg:an old lady mugged by a gang of youths in the park.在公园里遭一帮年轻人行凶抢劫的老太太.
此句中“mugged by...”作为定语修饰lady,其前面省略了动词“is/was”.
