选择题
While you are hurrying to the airport, _______in a heavy traffic jam in a taxi is quite an unpleasant experience．
A．having caught
B．being caught
C．caught
D．having been caught
答案
答案：B
本题考查非谓语动词。句意为：当你急着去机场时遇到堵车是多么不愉快的经历啊。being caught in引导的动名词短语作主语，并且表示被动。句子主语为“________in a heavy traffic jam”，其逻辑主语you为动作的承受者，故应用动名词的被动结构，而过去分词不能作主语，所以C项错误。D项时态不正确。
