各位同学，自从我们学会了名词变复数，我们经常会遇到一些比较特别的题现在我们来看下面这道题：将下列句子变成复数形式1．This dog is brown._________________________。

2. I am a student._________________________3.That woman is a teacher._________________________正确答案是什么呢？我们来看：

1： These dogs are brown.2： we are students.3： Those women are teachers.我们把this 变成了these，that变成了those，

is 和am 变成了are 这就是“另类的”复数形式现在我们来总结一下：这些复数形式其实是关于be动词，人称代词，指示代词的单复数概念的转换 主要注意一下几点：1. Is，am = are2. This = these。

That = those3. I = we me = us he she it = they him her it = them you = you my = our mine = ours his her its = their

his hers its = theirs yours = yours在这个过程当中，大家注意到没有要注意一个对等的原则比方说主格它的复数还是主格宾格它的复数形式仍然是宾格名词性物主代词它的复数形式也是名词性物质代词。

大家学会了吗？好的，请完成以下练习:将下列句子变为复数句1. That is a desk2. This is my chair.3. She gives me a pen.4. There is a child and a woman.
