Unit 2 This is my sister.（语法讲练） 单元语法一 【知识导图】 【要点拓展】 1.当this或that作主语时，be动词要用单数形式is，后面的名词也用单数形式；当these或those作主语时，be动词要用复数形式，后面的名词也用复数形式。 This/That is my book.这/那是我的书。 These/Those are my pens.这些/那些是我的钢笔。 2.this/that修饰单数可数名词，these/those修饰复数可数名词。 This/That girl is Alice.这个/那个女孩是爱丽丝。 Look at these/those books.看看这些/那些书。 3.在回答指示代词this/that作主语的一般疑问句时，不管指示代词指人还是指物，答语中都用it替代，结构为Yes, it is；No, it isn't。 —Is this your ruler? —Yes, it is. —这是你的尺子吗？—是的，它是。 —Is this your father? —No, it isn't. —这是你的父亲吗？——不，他不是。 4.在回答指示代词these/those作主语的一般疑问句时，不管指示代词指人还是指物，答语中都用they替代，结构为Yes, they are；No, they aren't。 —Are these your books? —Yes, they are. ——这些是你的书吗？ —是的，它们是。 5.向某人介绍某人时用指示代词，而不用人称代词。 This is my brother.这是我的哥哥。 6.打电话时，说自己是谁用This is...，问别人是谁用Who's that? Hello! This is Mary. Who's that?喂！我是玛丽。您是哪位？ 【奇思巧计】 指示代词有四个，分清意思别用错； this较近说话者，中文意思“这；这个”； that相对比较远，所指意思“那；那个”； these, those是复数，“这些”“那些”要记住； this, that来提问，用it回答是习惯； 问句用了these或those，用they回答最恰当。 【同步检测】 一、单项选择 1．—Hello, Tony. ________ is my friend Wang Wei. —Hello, Wang Wei.
