英語中，one、ones、that、those常用作代詞，指代前面出現過的名詞以避免重複，確保句子的簡潔。這些詞的一些用法非常相似，非常容易弄錯，今天Mr. Su 就來幫大家理一理，徹底搞清楚它們的區別和用法，三秒搞定它們吧。
一、用one, that ，ones, those填空。
A cake made of wheat tastes better than _one_ made of rice.
New pens always write better than old __ones____.
He told me the stories of himself and __those___ of his sister.
The school where my brother is studying is larger than __that___ where I am studying.
先來看看一般是怎麼來區別解釋的吧！
1. one用來指代「同名異物」的可數名詞單數。例如：
（1）－Do you have a car?
－Yes, I haveone. I have a good one. （one = a car）
（2）Yesterday I have lost my pen. I’m going to buy one after school. （one= a pen）
2. ones用來指代「同名異物」的可數名詞複數。例如：
（1）－Do you want a toy?
－Yes, I want new ones very much. （ones= toys）
（2）Teachers like the students working hard, especially the ones who areactive in thinking. （the ones= the students）
3. that用來指代「同名異物」的可數名詞單數或不可數名詞。例如：
（1）The weather of Beijing is as good as that of Tianjin. （that= the weather）
（2）The book you bought yesterday costs less than that I had boughtbefore. （that= the book）
4. those用來指代「同名異物」的可數名詞複數。例如：
（1）The houses of the rich are generally larger than those of the poor. （those= thehouses）
（2）The bikes made in China are as good as those made in USA. （those = thebikes）
是不是猛一看，挺難的呀！想不想用更簡單的方法解決呢？聽聽Mr. Su是怎麼總結的吧。
一般來講，one代表前面有不定冠詞的可數名詞單數，that代表前面有定冠詞的可數名詞單數；ones代表前面無定冠詞的可數名詞複數（前面總帶有形容詞作定語，不能單獨使用），those代表前面有定冠詞的可數名詞複數。
歸納一下：
that --the+ 名詞單數
one---a/ an + 名詞單數
ones-名詞複數
thosethe + 名詞複數
