why _______ you absent yesterday?a.did b.were c.was 为什么要选B,而不是A?
题中absent应该是形容词,因为如果他是动词就缺宾语.做动词时应该为：
why did you absent youself yesteday?
所以原句缺动词,所以选择B
absent的用法

2.用作动词,是及物动词,常接反身代词作宾语.表示“做某事缺席”,其后也接介词from：He absented himself from the meeting.他开会缺席.
3.点名时,若自己在场用 Here 或 Present (到,有)回答；若自己不在场,旁人可用 Absent (不在)回答.
