选D。caught somebody doing sth， 抓住某人做某事。固定搭配，CAUGHT 在这里接动词ING形式。楼上的不懂就不要来误人子弟，如果像你说的那样选A的话，Last night the policemen caught a thief when stealing Wang’s car就变成“昨天晚上警察在偷王先生的车时抓了个小偷”，成了警察偷东西了，笑死人！

选D的,偷车这个行为对小偷来说是主动，所以用现在分词来修饰小偷,为:a thief stealing Wang’s car,意为:偷王某车的小偷若选A的话,Last night the policemen caught a thief when stealing Wang’s car 为完整句式:Last night the policemen caught a thief when they(the policemen) was stealing Wang’s car 的缩略形式.所以此处修饰主语the policemen的.请回答别人问题的朋友，一定要仔细思考后再回答,以确保准确度哦.(如果带有猜测性的回答,最好注明.)

当然是选D了，若选A，那么就是警察在偷车子了啊。

D是正确答案。现在分词短语修饰名词the thief

选A，when stealing Wang’s car作定语修饰a thief
