分题答并解析,附加相关语法!谢谢

1.C
A形容一个人丢了,是sb is lost,所以这个词,应该是用lost做状语,而不是losing(一楼拼写有错),A错
B也不是被动形式,错
这种伴随状语只能是现在和过去分词,所D也错

2.B
fully修饰accepted(D不对),而且本句是方案被接受,所以被动语态(A,C排除)

3.D
regret doing sth后悔做过某事,动词固定用法,如
I believe you will regret leaving Paris.
我相信你会为离开巴黎而后悔的。

我不同意楼上回答第一题,我选C,lost in thought本身就是一个短语,它在句中作伴随状语,LOST有形容词的形式,不用ING的形式....

1 A.losting :he 发出的动作,所以用主动形式ing,
2 B.being fully accepted 被接受,用被动语态:fully accept:完全接受
3 D.having done :regret doing sth.:后悔作了某事,因为是已经发生的,对已经发生的事情后悔,所有用完成时:having done that.
