解放军文职考试：one、ones、that、those的区别

　　1. 一般来讲，one代表前面有不定冠词的可数名词单数，that代表前面有定冠词的可数名词单数;ones代表前面无定冠词的可数名词复数(前面总带有形容词作定语，不能单独使用)，those代表前面有定冠词的可数名词复数。例如：

　　(1)This is a point of idiom rather than one of grammar. (one= a point)

　　(2)A cake made of wheat tastes better than one made of rice. (one= a cake)

　　(3)I prefer the classroom with enough light rather than that with little light. (that= the classroom)

　　(4)The school where my brother is studying is larger than that where I am studying. (that= the school)

　　(5)I like peaches but I must have some ripe ones. (ones= peaches)

　　(6)New pens always write better than old ones. (ones= pens)

　　(7)He told me the stories of himself and those of his sister (those= the stories)

　　(8)I”d rather like the cars made in France than those made in Japan. (those= the cars)

　　2. one或ones的定语既可以放在其前面，也可以放在其后面;that或those的定语只能放在其后面。例如：

　　(1)He has got a new storybook, but I have got several old ones.

　　(2)This book is one that is needed by every one.

　　(3)The cost of oil is less than that of gas.

　　(4)The students who do best in examinations are not always those with the best brains.

　　3. 如果在one或ones前面加上定冠词the分别用来代表可数名词的单数或复数，定语又在其后，这时的the one或the ones基本上可以分别与that或those互换。例如：

　　(1)The singer from Shanghai sang better in the concert than the one / that from Beijing.

　　(2)She likes the car of herself, not the one/ that of her husband.

　　(3)The TV sets in that shop are as good as those / the ones in the supermarket.

　　(4)He”d prefer the places of interest in the countryside to those / the ones in the cities.
