Question

Sorry, I can't decide which one to buy now.后面的whi

Answer 1

问：Sorry, I can't decide which one to buy now.后面的which one to buy是填空我填成了to buy which one，能说说为什么不能这样填吗？

答：您好亲，Sorry, I can't decide which one to buy now.后面的which one to buy是填空错填成了to buy which one，是不可以的亲，which是形容词和代词，这里是指代物，后面不能直接跟不定式的亲

答：扩展，which引导定语从句。which前面加介词时时在句子里做宾语。如果从句中是动词短语作谓语，打动词短语中的介词就可以前置，放在which前边。例:Ifoundthatboxinwhichmybookswereput.在从句里应该是Mybookswereputinthebox.介词in便可以变在从句时前置。

问：你这讲的完全不理解，我认为是不是which one to buy这里的to buy 是不是动词不定式作后置定语修饰which one这个名词？

答：同学你好，这样的理解是不对的，首先which是代词，就是指代某一个东西或者物

问：你看你上面都给我讲糊涂了，你说which后面不能跟动词不定式，答案就是which one to buy，我不明白的点是为什么动词不定式要放后面而不是放前面，其实我也做出来了只是凭语感不知道语法是什么

答：您好亲，这其实看你的水平了，这是高中范围，也是which引导的非限制性定语从句与限制性定语从句的区别，

答：同学你好，这里的which是做定语的，修饰one
