備戰2016屆高考英語（通用版）一輪復習專題15 代詞
one前面一般不加a,因為它本身有“一個”的意思，但如果one前面有形容詞修飾，則需要加a/an。
one可以單獨使用，意思為“任何人”。例如：
—shall we have a rest?
—didn’t we just have one?(因為one=a something)
i happened to see a book about george w. bush, a nice one indeed.
one should always believe in oneself.
（2）that與those：
that可以代替前面提到的不可數名詞或可數名詞單數（相當于the one；而those 代替前面提到的復數名詞，有時可以用the ones替換。例如：
the population of china is bigger than that of india. (that=the population）
the boy told his story and that of the girl next room.(that=the story)
the cell phones we made nowadays are better than those/the ones made 2 years ago.（those=the cell phones=the ones)
（3）one和it:
兩者都可以用來代替前面出現過的單數名詞,one指這類東西中的任何一個，指類屬，泛指。it指前面所指的同一物。例如：
i need a pen to sign my name. can i have one? (one =a pen)
i cannot find my new pen. have you seen it?（it指那支新鋼筆）
3. another, the other, other, others, the others
（1）another和the other:
兩者都是“另一個”的意思，但數量上有區別:用 another指兩個以上的數量，而the other只指兩個中的另一個，例如：
he has three brothers, one is a teacher, another is a doctor and the third is an engineer.（當然如果還有第四個，五個就是the fourth, the fifth)
he has a book in one hand and a pen in the other.
注：another除了可以作代詞，還可以用作形容詞。這里有必要區別another, the other和more的用法：
①another:
another表“另一個”時只跟可數名詞單數，而表“另外的、額外的、附加的”時，可跟帶有few或具體數字的復數名詞，此時可把“數詞＋復數名詞”看作是一個整體。例如：
—have you finished your report yet？
—no，i will finish it in another 10 minutes.
there is room for another few people in the back of the bus.
②other:
表“另外的”接復數名詞，如與具體數詞連用，則置于數詞之后，但與定冠詞the連用時，other要放在數詞前。例如：
tony is going camping with two other little boys next sunday.
do you know where he found the other two photos？
③more:
more一般位于數詞之后,名詞之前，有時也可置于名詞之后。例如：
one more step（one step more），and i’ll shoot you.
where shall we be in ten more years？
more除跟數詞外，還可與many, a little，a few，a lot，several等詞連用，例如:
there are many more dictionaries on the desk.
would you like some more tea？
