Question

________in his test papers，he didn’t notice my coming.

1. A.
   Having absorbed
2. B.
   Absorbed
3. C.
   Absorbing
4. D.
   To be absorbed

Answer 1

B
试题分析：考查非谓语动词，be absorbed in（doing）sth“专注于”，做状语时用absorbed in…相当于：because he was absorbed in his test paper，句意是;因为专注于试卷，他没注意到我进来。选B。
考点：考查非谓语动词
点评： 英语中有些固定词组中有过去分词形式的形容词，做状语时可以直用过去分词的形式，如be buried in，be lost in，be devoted to等。
