1、不定代词用法注意点：1. one, some与any:1) one可以泛指任何人，也可特指，复数为ones。a. one作为代词可以指人，也可以指物。b. one，ones (one的复数形式) 可用来代替前面出现过的少数名词，以避免重复。c. one的前面可用this，that，the，which等词来修饰。d. 常有a+形容词+one这一形式。it和one的用法区别：it用来指特定的东西，而one则用于替代不特定的东西some多用于肯定句，any多用于疑问句和否定句。one should learn to think of others.ha
2、ve you any bookmarks? no, i don’t have any bookmarks.i have some questions to ask. 2) some可用于疑问句中，表示盼望得到肯定的答复，或者表示建议，请求等。would you like some bananas? could you give me some money?3) some 和any修饰可数名词单数时，some表示某个，any表示任何一个。i have read this article in some magazine. please c
3、orrect the mistakes, if any.4) some和数词连用表示“大约”，any可与比较级连用表示程度。there are some 3,000 students in this school. do you feel any better today?2. each和every:a. each用来指两个或两个以上的人或物中的一个。every则指两个以上的人或物中的一个。b. 从含义和语法功能上看，each是“单个”的意思，侧重个体，在句中可作主语、同位语、定语和宾语。而every是“每一个”之意，侧重全体、整体、共性。
4、在句中只能作定语，也就是说它后面必须跟着名词。而由every构成的合成词后面绝不能跟名词。each强调个别，代表的数可以是两个或两个以上，而every强调整体，所指的数必须是三个或三个以上。each student has a pocket dictionary. / each (of us) has a dictionary. / we each have a dictionary.every student has strong and weak points. / every one of us has strong and weak po
5、ints.3. none和no：no等于not any，作定语。none作主语或宾语，代替不可数名词，谓语用单数，代替可数名词，谓语单复数皆可以。there is no water in the bottle.how much water is there in the bottle? none.none of the students are (is) afraid of difficulties.4. other和another: a. another＝another"另一个”，泛指众多者中的另一个，在原有基础上自然增加的另一个。一般后面接单
6、数名词，前面不能加定冠词。有时another可以用在复数名词前表示“又”“再”，如： i want to have another two cakes．我想再吃两个蛋糕。b．the other表示两个中的另一个，常与one连用。常见形式是“one．．．the other．．．”。 c. other+复数名词＝others d. the other+复数名词＝the others1) other泛指“另外的，别的”常与其他词连用，如：the other day, every other week, some other reason, no oth
7、er way, the other特指两者中的另外一个，复数为the others。如：he held a book in one hand and his notes in the other.two students in our class failed, but all the others passed the exam. 2) another指“又一个，另一个”无所指，复数形式是others，泛指“别的人或事”如：i don’t like this shirt, please show me another (one). the
