定指右邊的（ on the right),所以要用定冠詞that 也是特指啊，當(dāng)有后置定語(yǔ)修飾時(shí)，通常用 the one。如：My room is better than the one next door. 我的房間比隔壁房間好。He said he would have the one near him. 他說(shuō)要靠近他的那一個(gè)。但是，若后置定語(yǔ)為 of 引起的介詞短語(yǔ)，則通常用 that。如：The population of China is much larger than that of Japan. 中國(guó)人口比日本人口多得多。A grandparent’s job is easier than that of a parent. 祖父母的任務(wù)比父母的任務(wù)要輕松一些。
