Answer 1

187.A
分词作状语,表示伴随.
相当于as if 引导的状语从句：
The professor paused as if he was expecting his students to ask questions on the point he had just made.
例如：John stood at the school gate as if waiting for someone.
as if 还可以引导动词不定式：
John bent down as if to pick up something on the ground.
相当于：John bent down as if he wanted to pick up something on the ground.
188.选 D.
原因状语从句.
如果选择非谓语动词,句子主语与非谓语逻辑主语必须保持一致.
如：
Intended to go abroad,he spends his spare time totally in learning English.
=As he has been intended to go abroad,he...(相同主语）
或者：
Having made up his mind to go abroad,he spends his spare time totally in learning English.
= As he has made up his mind to go abroad,he...（相同主语）
本题主语是his spare time,所以只能用完整的原因状语从句了.
再给一道类似例子：
Having done such a good job,Mary walked out to have a rest.(正确）
Having done such a good job,the teacher praised Mary.(错）
第二句改为：As she had done such a good job,the teacher praised Mary.
