我们经常在写作文，做完形填空和单选题的时候，经常会犹豫，这个情况究竟是可数名词，还是不可数名词；用单数还是用复数形式。今天我们总结一下用可数名词复数的情况。
一，这些词如果接可数名词，必须是复数
He has many friends. （many）I have a lot of dictionaries.（a lot of）They worked out lots of problems.(lots of) 他们解决了许多问题。There are a number of trees on the hill.（a number of）山上有许多树。My cousin has a few good pens.（a few）我的表弟有几只好钢笔。The boy has few good pens.(few)那个男孩没有几只好钢笔。They have a good many bamboo flutes. (a good many)他们有许多竹笛。I have some good friends in Beijing.(some)我有一些好朋友在北京。The teacher has plenty of old clothes.(plenty of) 那位老师有大量的就衣服。We met several foreigners yesterday.(several)我们昨天遇到了好几个外国人。These people were very friendly.(these)这些人很友好。Those children are happy in the park.(those)那些孩子在公园里很快乐。All the students attended the meeting.(all)所有的学生都参会了。The old woman enjoys helping other people.(other)这位老太太喜欢帮助别人。Do you know any teachers in this school?(any)你认识这个学校的老师吗？The man can write with both hands.(both)这个人会用两只手写字。The girl learned different kinds of musical instruments.(different)这个女孩学过几种不同的乐器。二，可数名词左边如果没有数量限定词，那就只能是复数形式（固定短语除外）。很多学生都不知道，从而，没有用复数形式，这在书面表达中是大忌。
We have friends all over the world.我们的朋友遍天下。There are apple trees on the farm.农场里有苹果树。I saw good dictionaries in the bookstore this morning. 今天早上我在书店看见了几本好词典。Students should respect teachers.学生应该尊敬老师。Excellent teachers are always polite to the other teachers in schools.优秀的老师对学校其他老师一般都很有礼貌。Ill-mannered young teachers are not so polite as students, which is common. 自以为是的年轻老师还没有学生讲礼貌，这种现象目前很普遍。My favorite fruit is apples. 我最喜欢的水果是苹果。Apples are my favorite.苹果是我最喜欢的。Tom likes playing football, and he has several footballs. (play football是固定短语，不用复数形式)My favorite sport is football. （football泛指足球运动，不用复数形式）Football is my favorite sport. We go to school by bike. (go to school，by bike 都属于固定短语)来源：郑老师KMYYZY
