1、物主代词。

   怎么区分开名词性物主代词和形容词性物主代词？例如my和mine，它们最重要的区别是?my的后面一定要接名词，不可以单独出现，只能做定语，如：my father；而 mine则是名词性，只能单独出现，在句中做主语和表语。如：Mine is green. It's mine. 记住这两个句子，名词性物主代词还有：yours, hers, his, its, ours, theirs等。这样，通过它们出现的位置不同，我们就可以把它们区别开了。

　2、反身代词

  代词末尾加上"－self(selves)"则变成反身代词，表示“自己、亲自”的意思。反身代词不能单独做主语，但可以放在人称代词后面，做同位语。如：Marry herself said so. 玛丽她自己这么说的。（不能说Herself said so.）

   3、Of+名词性物主代词：构成双重所有格。公式为：a（an, this, that ）+名词+of +名词性物主代词。因为物主代词不可与 a, an, this, that, these, those, some, any, no, each,every, such, another等词一起前置，修饰一个名词，而必须用双重所有格。如： a friend of mine（我的一个朋友），each brother of his（他的每一个兄弟）.
　 4、some, any的用法：我们都知道some用于肯定句中，而any则用于否定句和疑问句中。 所以somebody，someone也用于肯定句中，而anybody、anyone则用于否定和疑问句中。
　　注意：在Would you like some coffee?（要来点咖啡吗？）这样的肯定疑问句中，说话人认为对方的答案会是肯定的，或期望得到肯定回答时，用some而不用any。
　　5、every 和each的用法：every 强调全体的概念，指三个以上的人或物(含三个)，不可单独使用；each强调个体概念，指两个以上的人或物 (含两个)，可单独使用.。Every student in our school works hard.（我们学校的学生都很用功。） Each student may have one book.. （每个学生都可有一本书。）
　　6、both, either, neither的用法：
　　both意为“两者全都”，与复数连用。either意为“两者中间的任何一个”，neither 表示“两者之间一个也不是”，与单数连用。如：Both of  them come from London。他们两人都是伦敦人。 You may take either with you。 两个中间你随便带哪个都行。 Neither is correct。 两个都不对。
　　7、Few，a few和little，a little的用法：
　　Few，a few用来代替和修饰可数名词，little，a little用来代替和修饰不可数名词;a few和a little 着重肯定意思，相当于汉语“有几个”，“有一点儿”；few和little 着重否定意思，相当于汉语 “没有几个”，“没有多少”
