C.seated (remain是连系动词,故用形容词seated作表语.remain seated 保持坐着的状态)2.B.setting up (考查短语devote sth.to doing sth.) 3.A.he explained he explained at the meeting for his carelessness ...答案是全对,但第一题没懂,为什么不能选B?seat 作动词时,只能用于被动结构: be seated"就座,入座",没有现在分词形式的.那有没有remain doing的用法有啊, 如上面的remainseated可换成:remain sitting 又如: He was uncertain whether to stand up or remain sitting. 他拿不准是站起来好还是继续坐着好.
