1樓不對(duì)啊
這個(gè)不是省略先行詞的定語(yǔ)從句
rob很特殊
rob a person/bank 表示打劫 但沒(méi)說(shuō)明奪走什么
rob sb of sth 表示從誰(shuí)手上搶走什么
rob him of all his possessions
（比喻用法）The accident robbed him of his health.
這里只是用get轉(zhuǎn)化為一個(gè)被動(dòng)的句型
She was robbed of her watch.
She got her watch robbed of.
就好像have sth done一樣
She has her hair cut this morning.
只是動(dòng)詞的形式中有介詞 就比如
She has the paper on the ground picked up.她讓人把地上的紙撿了起來(lái)
