20、those來直接修飾，除非ones前面有形容詞：e.g.:I have a new coat and several old ones.These yellow waistcoats are so small. I want those ones.one/ones用來代替前面提到過的可數(shù)名詞，one指代單數(shù), ones指代復(fù)數(shù)，所代替的是同名異物，表示泛指，可有前置定語或后置定語，也可單獨使用，特指時必須加 the，用the one/ones 。一、where定語從句修飾pointYou reach a point where medicine cant help. 你已到了藥物無法治療的地步
