答案D. have(讓，使）＋賓語＋do/doing/done.當賓語與其后動詞是被動，用done.主動用do或doing.當表示進行時用doing.經常做或已做過用do.如：I have him do his homework at home. I have him doing his homework at home now. I had him do his homework at home last night.注意：see,look at, hear, listen to, abserve, notice,watch,feel 等與have 用法相同．注意：make +賓語＋do/done,沒有doing形式，而find+賓語＋doing/done,沒有do形式．

記住這句句型 have sth done 如have tooth pulled. have the worker fired.

被動啊。牙肯定不是你自己拔而是牙醫動手。前面是“'d better Have sth."，后面是被動無疑。
