22、Theyre mine.Conversation 4 1.学习指示代词,应注意以下几点:this与is,these与are没有缩写形式。This is a Chinese car.这是一辆国产轿车。指示代词作主语指物并用于问句中时,回答一般用:it代替this和that;they代替these和those。-Is that a ruler?那是尺子吗?-No,it isnt.Its a pen.不,不是。是钢笔。-Are these your books?这些是你的书吗?-Yes,they are.是的。2.no和not二者都是“不”的意思,用法不同。no:可单独使用,用于回答一般疑问句,反义
23、词为yes;not:不能单独使用,要和be动词、助动词等一起构成否定句。-Is this your pencil?这是你的铅笔吗?-No,it isnt.不,不是。It is not my book.这不是我的书。3.sorry adj.抱歉的sorry:是Im sorry的省略形式,用于冒犯、冲撞了他人或伤害了对方等场合。常用的回答:Not at all.没关系。Thats all right.没关系。It doesnt matter.不要紧,没关系。Never mind.别在意,没关系。sorry还可表示“遗憾的;难过的”等。Im sorry to hear that.听到那个消息我很遗憾
24、。4.Thanks for 意为“谢谢”,因某事感谢某人。后接名词/动名词。=thank sb.(某人)for sth.Thanks for your help.=Thank you for your help.谢谢你对我的帮助。Thanks for his beautiful card.=Thank him for the beautiful card.谢谢你给我这么漂亮的卡片。5.in prep.用(方法、媒介、工具等);使用(语言)。如:John is drawing a car in pencil.约翰正用铅笔画汽车。We always speak in English.我们总是用英语

26、heirs形容词性物主代词名词性物主代词Grammar focusThis is a pencil.Is this a pencil?This is my pencil.Is this your pencil?一般疑问句一、含义以动词be,助动词、情态动词开头,以yes或no作回答的问句叫做一般疑问句。回答时大多数情况下只需作简略回答。二、构成及答语句中有动词be(am,is,are),将动词提到主语前,并大写开头字母,句末用问号,主语第一人称变第二人称,即变成了一般疑问句。一般疑问句要用Yes或No来回答。它的肯定答语是Yes,it is.否定答语是No,it isnt.注意:答语用it代替
27、this/that。Thisismypencil.Is thisyourpencil?含有be动词的陈述句变为一般疑问句的步骤-Is this your pencil?这是你的铅笔吗?-Yes,it is.是的。-Do you have any magazines?你有杂志吗?-Yes,I do.有。1.-Is this your _ _?-Yes,_ you._ that is _ _.2.-_ this _ key?-Yes,_ is._ mine.pencilboxthankAndmyschoolbag.根据图片完成句子。IsyouritIts解析:Its是It is的缩写形式,It指代
28、this;“Its mine.”=“Its my key.”Exercises3.Heres _ _.aneraser解析:a和an都是不定冠词,放在单数可数名词前,修饰限定名词,表示“一个、一块”的意思。名词的读音以辅音音素开头,用不定冠词a,如:a banana,a pear;名词的读音以元音音素开头,要用不定冠词an,如:an orange,an egg。单词eraser是以元音音素 i 开头的词,故要用冠词an。.按要求写出下列词的相应形式。1.hi(同义词)_2.no(反义词)_3.are(同音字母)_4.color(动词)_5.I am(缩写形式)_6.u(同音词)_7.my(主格
