问题描述：
we have two rooms to live in,but we haven't decided which one to choose.
which one to choose.为什么不用to choose which one?
答
which one to choose是这个句子的从句，像where which why等疑问词都要放到句首的，不要汉语顺序英文
答
都对啊！只不过英语句子多为头重脚轻，which one 两个词，放前面。
答
这个语法结构叫“疑问词 + 不定式”,该结构相当于一个名词（短语）,在句中充当主语/宾语/表语等成分.如果是疑问代词,则疑问词一般充当不定式中某个动词或介词的宾语.如：I don't know what to do.what to do 做know...
答
虽然有decide to do sth.的句型，但这里用的是which（关系代词）引导的宾语从句
