题目

先行词是something,关系代词除了that 还能用什么?
我又查了好多资料,才发现 something 做先行词的话,除了that 还可以用which.例如:(1)Suppose someone has done something to make you angry.Think about something which will make you happy.The best antidote to negativity is to focus on the positive.
(2) The future is something which everyone reaches at the rate of sixty minutes an hour,whatever he does,whoever he is.
(3) Happiness is absolutely not something which can be achieved by one person alone
所以,限制性定语从句中只能用that 引导定语从句的情况之一就是
当先行词是everything,anything,nothing (something 除外),all,none,few,little,some等不定代词时，或当先行词受every,any,all,some,no,little,few,much等代词修饰时。

答案

你这个算是有结论了么?
