问题描述：
He was made to clean the room a second time.那个second序数词前为什么不加定冠词the 而是a?
答
a second time．．这里强调的是已经打扫过一次了．
the second time强调的是：次序，即”第二次”．
答
a是说另一次，又一次，并不强调动作；而定冠词The 是特指，有强调的意思。
不知道这样说明白吗。
答
a second time 再,又的意思 固定用法
如果要用the second time的话,就要It is the second time that he was made to clean the room.这里就成第二次了.
