英语定语从句中that和the one that 用法有哪些不同?

Answer 1

one 用作替代词主要用于替代“a＋单数可数名词”,表泛指；若需特指,则用 the one.如：A fast train is one that goes fast.快车是一种行驶快的火车.The accident was similar to one that happened in 2008.这个事故与发生在2008年的事故类似.Open the drawer on the left,the one with a key in it.打开左边的抽屉,上面有钥匙的那个.Here are six rings.Pick out the one you like best.这里有六枚戒指,选出你最喜欢的一枚.I want very much to see these films,especially the one you mentioned.我很想看这些电影,特别是你提到的那一部.注：the one与that均可表特指,但前者只用于替代单数可数名词,而后者则可用于替代可数或不可数名词.
