题目

advance表示提前可数吗,即in advance中的advance可数吗.
我知道:表“前进”时不可数,表名词“进展”、“进步”时可数,凡是前进≠提前吧.

答案

in advance
in advance of
（提前,在前）
的 advance 不可数.
这两个词组是成语,句型不能改.
例句：
How far in advance of the wedding should invitations be sent out?
Reservations for the performance should be made well in advance to ensure you will get the seats you like.
