过去将来时的被动语态would be+动词的过去分词
he never expected the bicycle to be found为什么不能写成he never expected the bicycle to would be found呢

被动语态:主语是动作承受者主动语态:主语是动作的发出者结构:1.一般现在时的被动语态结构:主语+be(amqismare)+动词的过去分词+宾语+其它      2.一般过去时的被动语态结构:主语+be(was0were)+ 动词的过去分词+宾语+其它      3.一般将来时的被动语态结构:主语+will/shall+be+动词的过去分词+宾语+其它      4.现在完成时的被动语态结构:主语+have/has been+动词的过去分词+宾语+其它

用的是expect ..to do 结构.全句的时态是一般过去式(expected), 期望这个词含有将要做的意思,反而一般不用将来时. 不定式 to do 的被动式是 to be done, 所以为 to be found. 不定式符号to 之后要用动词原形,而would 就不是实意动词,更不是原形.
