her mother's decease deprived her of her last hope for life.老大her last hope for life.做宾补

1deprive虽然是及物动词，但后面＋of，有不同的意思 ＝ deny（这也是一个固定用法）

deprive 的意思：

①To take something away from

② To keep from possessing or enjoying; deny

③ To remove from office.

但②的用法，常常是＋of的，即deprive of， deprive sb of sth = to prevent from possessing or enjoying. －－ 这和①的意思稍有差别，是① 的意思引申。

2of 不是由于前面有2个her，比如：to deprive a child of affection.
