选择题
(2013·皖南八校联考) ________ a lady of her necklace, the young man was arrested on the spot by a policeman.
A．Having caught robbing
B．Caught robbing
C．Being caught robbing
D．Catch robbing
答案
答案：B
选B 考查非谓语动词作状语。句意：那个年轻人在抢一位女士的项链时被发现了，警察当场逮捕了他。catch sb doing sth.表示“发现某人正在做某事”，catch与the young man为动宾关系且表示完成，故用过去分词。
