【学习目标】
1、学习识别复数物体。
2、学习可数名词的单数和复数形式。
【知识点击】
―What are these？这些是什么？
―They are books.它们是书。
(1)these是this的复数形式，指距离说话人较近的多个人或物；those是that的复数形式，指距离说话人较远的多个人或物。
(2)these或those作主语，后跟的be动词用are,否定形式are not,可缩写为aren’t.如：
These are oranges.Those are eggs.这些是橘子，那些是鸡蛋。
These aren’t books.这些不是书。
（3）在回答主语是these或those的疑问句时，答语通常要用they代替问句中的these或those。如：
―Are these your cars?这些是你们的汽车吗?
―Yes,they are.对，这些是。
―Are those her pencils?那些是她的铅笔吗？
―No,they aren’t.不，那些不是。
【链接】What’this∕that?与What are these∕those?的区别；
Is this∕that a(an) …?与Are these∕those…?的区别
What are these∕those?是What’s this∕that?的复数形式；Are these∕those…？是It this∕that a(an) …？的复数形式。
【拓展】怎样把句子由单数形式变为复数形式？
主要遵循以下五步：
主语this→these，that→those，I→we，he/she/it→they。
be （is/am）→are。
把不定冠词a/an去掉。
疑问词，介词短语，物主代词不变。
把单数名词变为复数名词。如：
1 What’s this in English? 这个用英语怎么说？
→What are these in English? 这些用英语怎么说？
2 It is a book.它是一本书。 → They are books.它们是一些书。
3 He is a boy. 他是一个男孩。 → They are boys. 他们是一群男孩。
