问题补充:
in the front row at the ceremony, our distinguished guests are from home and abroad.
A. Seating
B. Being seated
C. Seated
D. To seat
答案:
A. Seating
B. Being seated
(答案→)C. Seated
D. To seat
解析:考察分词作状语。本题中的动词seat使…就座;这是一个及物动词,与后面句子的主语our distinguished guests构成被动关系,故使用过去分词在句中作状语。本句中的seated已经转换成形容词“就坐的…”;句意:坐在庆典前排的是我们来自国内外的尊贵的客人。故C正确。
