Grammar Focusthat’s＝that is　 who’re＝who are
who’s＝who is　they’re＝they are(一)指示代词this, that, these, those语法讲解 含有指示概念的代词叫做指示代词。this, that, these和those都可作指示代词，分别表示“这个”、“那个”、“这些”和“那些”。指示代词在句子中可作主语、宾语、表语、定语等成分。考点 1 指示代词是表示“这个；那个；
这些；那些”的代词。其中，this(这个)
和these(这些)指离说话人较近的人或事物； 【重点】 that(那个)和those(那些)指离说话人较远
的人或事物。
eg：This is Jenny and that is Alice.
这是珍妮，那是艾丽斯。
These are pears and those are apples.
这些是梨，那些是苹果。典例—Look! Do you know ________ man under the
tree?
—Sorry. It’s too far to see ________ clearly.
A．this; him B．that; his
C．this; her D．that; himD【点拨】本题采用寻找题眼法。too far 说明太远，远指用that，man说明是男的，第二空作see的宾语，要用宾格形式him。典例That ________ my aunt.
These ________ our bikes.(is, are)is【点拨】本题采用主谓一致法。that后用单数is, these后用复数are。考点 2 指示代词this, that 作主语时，系动
词be用单数形式is，同时后面的名词用单数形式；
当these，those作主语时，系动词be用复数形式
are, 同时后面的名词用复数形式。are【重点】 考点 2 在回答主语是this或that 的一般疑问句或特殊疑问句时，在答语中用it代替问句中的this或that 。当回答主语是these或those的问句时，在答语中用they来代替句中的these或those。【易错点】 典例 2 —Are these your cousins?
—No, ________ ________．they aren’t　【点拨】主语是these的疑问句，回答时主语用they代替，
且are与not可以缩写。典例 1—Is that your mother?
—Yes, ________ ________．
【点拨】[易错点]主语是that的疑问句，回答时主语用it
代替， 且it is不可缩写。it is who用作疑问代词，指人，可用作主语、宾语、
表语等成分。(二)who引导的特殊疑问句考点 1 who用于实义动词前作主语，且提问
时常用作第三人称单数。【易错点】典例—________likes science?
—My friend Rosie.Who　【点拨】由答语可知问句为对人的提问，故填Who。典例—________is your maths teacher?
—Ms. An.【点拨】提问人用who。who用于be动词之前作主语。考点 2—________is your maths teacher?
—Ms. An.Who 英语中，名词分为可数名词和不可数名词。不可数名词没有复数形式；可数名词在表示多个人或物时用复数形式。可数名词的复数形式一般是在词尾添加-s或-es构成。(三)名词复数 名词复数的变化规律如下表：考向 【重点】 口　诀
(1)在以f，fe结尾的名词中，变f和fe为v加-es的需记这样一句话：一个小偷(thief)的妻子(wife)用树叶(leaf)做的小刀(knife)杀死了一只狼(wolf)，把它劈成两半(half)，挂在衣架上(shelf)。
(2)在以o结尾的名词中加-es的：
　黑人英雄在火山上吃西红柿和土豆。
? ↓　↓　 　↓　　　↓　 ↓
?Negro hero volcano　tomato　potato
(3)在单复数同形的单词中，中(Chinese)日(Japanese)不变，英法变，其余-s加后面。魔法记忆 代词是代替名词的词， 按其意义、特征及其在句中的作用分为：人称代词、物主代词等。人称代词有主格和宾格之分。(四)人称代词人称代词的人称、数和格，如下表所示：Complete the conversation and practice it with your partner.3aA：That ________ my family. That’s my mother.
