Question

定语从句中如果先行词是the reason, 那么可以用连接词that, why, for which, 那么请问如果这三个用法在同一道题中出现, 应该怎样选择？

Answer 1

当先行词是anything、everything、 nothing 之类的这种不定代词的时候，或者有every, all、 little、 few、 much等修饰的，（这时候that可以省略） 还有先行词前有序数词或形容词最高级修饰时,以及句中前面有which时,都只能用that引导 前面是介词一般都用which 比如你们肯定都讲过 in which=where on which=when 之类的

Answer 2

能用why的就可以换用for which，这两个是副词意义。所以此题必选that，它在从句中代替名词代词本回答被提问者采纳

Answer 3

why
