1.___himself,he hurried to the office without breakfast,or he would have late.
A Dressed B Having dressed C Dressing D To dress
答：C
译：他一边穿衣服，一边急着去公司上班，连早饭都没吃，不然他准迟到了。
析：本题考非谓语动词作状语。dress是及物动词，跟sb./ oneself作宾语，这里是himself 表示‘给自己穿衣服’，是主动的关系，排除A. dressed, 这个过去分词。 不定式表示目的=in order to ..., 意为：为了。。。， 不合句意，排除D
B. Having dressed 是现在分词的完成式，强调时间，相当于After he had dressed himself, 意为：在他穿戴好之后。也说得通。可能此题有争议。
C.Dressing是现在分词的一般式，表示与hurried 同时发生的动作，译作一边。。。一边。。。本人觉得比较符合语境。所以我认为最佳答案为C。
2.__by anyone,the little boy left the hotel ,which worried his parents a lot.
A Not seen B Not having been seen C Not seeing D Not having seen
答：A
译：小男孩离开了宾馆，没人看见，这让他的父母很着急。
析：本题考查非谓语动词作状语。男孩和see是被动关系，排除现在分词CD。
B。为现在分词完成被动否定式，相当于时间状语从句After he hadn't been seen by anyone, 显然不符合句意。而A. Not seen by anyone只强调被动，不强调时间的先后，相当于一个原因状语从句=As he was not seen by anyone, 不过，我感觉更象是伴随情况。
