解答:
1.The boy went to the ball, _D__like a pretty girl.
A. dressing B. wearing C. wore D. dressed
2. _A__ in a white uniform, he looks more like a cook than a doctor.
A. Dressed B. To dress C. Dressing D. Having dressed
过去分词组状语.He is dressed in a white uniform....
be dressed in...被动
5. ___B__ to his research, he almost forgot everything.
A. Devoting B. Devoted C. To devote D. Devote
过去分词的用法， devote是一个及物动词，后面跟宾语，如后面没有宾语，只能用它的系表结构/被动结构be devoted to.
6. __B__his attention on his novel, he didn’t notice the teacher coming.
A. Fixed B. Fixing C. Fix D. To fix
7. __A__ on his novel, he didn’t notice the teacher coming.
A. Fixed B. Fixing C. Fix D. To fix
他把注意力集中在小说上,所以没注意老师来.fix与he构成被动关系，用to do形式,则表目的
10. __D___ the past, our life is becoming much better.
A. Comparing with B. Be compared with C. To compare with D. Compared with
15. __D___of plastics, the machines are easy to carry.
A. To make B. Having made C. Being made D. Made
