1、Unit 2 This is my sister.第三课时 Section A(Grammar Focus3c)单元语法精讲一、指示代词表示“这个”“那个”“这些”“那些”等指示概念的代词叫指示代词。1.this,these是近指,一般用来指时间或空间上较近的事物；that,those是远指,常用来指时间或空间上较远的事物。this,that指代单数,these,those指代复数。eg：Is this your pencil?这是你的铅笔吗?These are my friends.这些是我的朋友们。Is that his book?那是他的书吗?Those are my brothers.
2、那些是我的兄弟们。2.回答this/that,these/those作主语的问句时,常用it和they分别代替this/that和these/those。eg：Are these/those your English books?这些/那些是你的英语书吗?Yes,they are.是的,它们是的。Whats this/that?这/那是什么?Its a ruler.它是一把尺子。3.介绍在一起的人或物时,先说this/these,后说that/those。【注意】this is,these are,those are都不能缩写,而that is可以缩写成thats。二、who的用法主要用来询问
3、某人是谁,常用来引导特殊疑问句。eg：Whos she?她是谁?Whos he?他是谁?Whore they?他们是谁?这些都是由who引导的特殊疑问句。who是特殊疑问词,意为“谁”。另外,who可与is,are缩写,who is=whos,who are=whore。单元语法强化训练一、从括号中选择正确的单词或词组完成句子。1.(These are/This is)my parents.2.(That is/Those are)my friends.3.What color are(these/this/they)jackets?These areThose are these二、根据汉语
