重點(diǎn)看謂語(yǔ)部分：

Shesentmeanovelonmybirthday.

主謂間接賓語(yǔ)直接賓語(yǔ)狀語(yǔ)

Iallowedhimanhourtofinishthework.

主謂間接賓語(yǔ)直接賓語(yǔ)狀語(yǔ)

如果選直接賓語(yǔ)作“主語(yǔ)”，有時(shí)要在被動(dòng)態(tài)句子的“保留賓語(yǔ)”前加上合適的介詞。因?yàn)檫@些動(dòng)詞常有兩種句式，即：我們可以說(shuō)givesb.sth.,sendsb.sth.,buysb.sth.；我們也可以說(shuō)givesth.tosb.,sendsth.tosb.,buysth.forsb.。請(qǐng)看下面兩種情況的對(duì)照：

Shesentmeanovelonmybirthday.(主動(dòng))

Iwassentanovelonmybirthday.(被動(dòng))

Anovelwassenttomeonmybirthday.(被動(dòng))

關(guān)于帶有復(fù)合賓語(yǔ)的主動(dòng)態(tài)變成被動(dòng)態(tài)

如果將帶有復(fù)合賓語(yǔ)（即：賓語(yǔ)+賓語(yǔ)補(bǔ)足語(yǔ)）的主動(dòng)態(tài)的句子變成被動(dòng)態(tài)的句子，我們只能選擇原來(lái)句子的賓語(yǔ)作被動(dòng)態(tài)句子的主語(yǔ)；而這時(shí)，原句里的賓語(yǔ)補(bǔ)足語(yǔ)現(xiàn)在就變成被動(dòng)態(tài)句子的“主語(yǔ)補(bǔ)足語(yǔ)”了。
