Though I tried to reason with them, I was ________ in chains and thrown to ________ prison.
A.worn; theB.kept; aC.put;/D.set; that在线课程C
解析：
【巧解导析】本小题考查动词搭配及冠词的用法．第一空表示“我被铁链锁住”用put sb. in chains；第二空表示“把某人投入监狱”用throw/put sb. to/into prison，此时prison表示抽象概念“坐牢”，因此不加冠词．类似用法还有put sb. to school，be in hospital等．
