问题描述:

When all those present(到场者)__ he began his lecture.A.sit B.set C.seated D.were seaed

选D,be seated固定词组

D

D were seated
A sit 是不及物动词.这里是不是该用 sit down
B set 作动词时是放置物品或是某物,某人处于某种状态,没有就座的意思.
C seat 的特点是作动词时为及物动词,后面必须有宾语或用其被动语态
如:Be seated,please.请坐.(很礼貌的用法)
seat sb.某人就座(有安排,使的意味 ) seat yourself ,seat him

D
were seated.
请坐:Please be seated。 记住这句话就知道seat怎么用了
