选择题
—Our holiday cost a lot of money.
—Did it? Well, that doesn’t matter _______ you enjoyed yourselves.
A．unless
B．in case
C．as far as
D．as long as
答案
D
第二个人说的话中含有一个由as long as 引导的条件状语从句，句意为“度假花了不少钱。”“是吗？那也没什么，只要你们玩得高兴就行。”又如：“Our profits will be good so long as the dollar remains strong.”。句中动词cost的三种形式相同，that替代上句中的cost a lot of money是一种句子性替代。
