定语从句求解释
Do you know the most interesting story _____ took place long ago.
为什么不能填which而是用that
答
以下是定语从句中只能用that的情况：
(1)当先行词是指物的all,little,few,much,any,anything,everything,nothing,none,the one时,或先行词被all,little,few,much,any,every,no等修饰时.
(2)先行词是序数词或*形容词时,或者先行词被序数词(包括last,next)、*形容词及the only,the very等修饰时.
(3)先行词包括人和物时.
(4)当主句是以who或which开头的疑问句时,为了避免重复,多用that引导.
你的这道题符合其中第（2）项,所以选that.
