问题描述：
After________ by the police for several days,the robber had to give in.
surrounded和being surrounded都可以吗?
答
只有surrounded可以，后面的那个时态不正确
答
after是介词，后面加动词的ing形式，所以我觉得应该填being surrounded
如果要选surrounded，则将surrounded放于句首。
Surrounded by the police for several days, the robber had to give in.
答
after是介词.介词后面的动词必须是动名词（-ing开头的动词）.surround是及物动词,后面应该有宾语.如果没有宾语就必须是被动语态.所以,你的句子就成了being surrounded.
