Period Five　Writing—Writing an expository essay写作指导说明文是近年来高考英语书面表达比较常见的一种体裁。说明文是以说明为主要表达方式的文体。它主要用来说明事物的特点和发展变化的规律，有时候添加个人评价，目的在于使读者获得必要的信息，对事物有更清晰、完整的了解和认识。基本要求：1．特征要明确对某一事物予以说明，首先要弄清从哪些方面加以说明才能准确地反映被说明的事物。一般来说，说明事物可以从事物的颜色、形状、习性、结构、用途、操作过程、发生及发展规律等方面着手。但每一件事物都有其自身的特征，因而写作时不需要面面俱到，要着重突出这一事物区别于其他事物的特点，这样才能给读者留下具体而深刻的印象。2．层次要分明说明事物要注意条理，否则就不可能说清楚复杂的事物。例如说明事物的构造，就要按照构造的顺序来说明，或从上到下，或由里及外，或由主到次。文字要简明扼要，一目了然。3．说明手法要多样常见的说明手法有：下定义、举例子、作比较、分类别、列数据、列图表等。4．结构要完整写说明文宜采用三段式：第一段主要介绍要说明的对象及说明的目的；第二段说明事物的主要特征；第三段进行总结概括。在结尾段要突出题目要求，重申说明目的，使文章完整。5．语言要得体说明文写作应尽量使用客观公正的语言，不要使用太多夸张的修饰词和表达个人观点的语句，因为你是在客观说明而不是发表议论。为达到这一效果，应多使用被动句，句子不要太复杂，最好长短句结合。常用表达1．引入：(1)I’m very glad to know ...(2)Hearing that...(3)I wonder if you ...(4)We are used to...(5)We may find it...2．阐述：(1)I’ve found a ...(2)It has an area of ...(3)Moreover.../What’s more...(4)However.../Instead...(5)It is as big as...(6)It is in the east of...(7)We’d better...3．总结：(1)If anyone wants to know more...(2)If you need further...(3)It’s good for us to ...(4)I believe you will be ...(5)I hope you will...假定你是李华，自制了一些中国结(Chinese knot)。请你给开网店的美国朋友Tom写封信，请他代卖中国结，要点包括：1.外观(尺寸、颜色、材料)；2．象征意义；3．价格。注意：1.词数80左右；2．可以适当增加细节，以使行文连贯；3．开头和结尾已为你写好，不计入总词数。审题1．确定文体：说明文；2．主体时态：一般现在时；3．主体人称：第一、三人称。谋篇第一段：开篇问候，说明写信的目的；第二段：详细说明中国结的外观、象征、价格等信息；第三段：说明联系方式，并告知可以提供更详细信息。核心词汇1．亲自制作make sth.oneself2．以……形状in the shape of3．代表stand for4．好运good luck5．更多信息further/more information连词成句1．人们可以把它们作为礼物送给朋友，也可以把它们挂在家里或车里。(either...or)People can either give them as gifts to friends or hang them in their houses or in their cars.2．这很可能会给人们带来非凡的体验。(be likely to)This is likely to give people an extraordinary experience.3．如果你需要进一步的信息，请告诉我。(条件状语从句)Let me know if you need further information.句式升级1．将句1、2用定语从句连接起来People can either give them as gifts to friends or hang them in their houses or in their cars，which is likely to give people an extraordinary experience.2．强调句3主句的谓语动词Do let me know if you need further information.用适当的过渡词语，把以上词汇和句式，再加上联想内容，组成一篇80词左右的英语短文。Dear Tom，How are you doing？I wonder if you could sell some Chinese knots for me.                                                                                                                                                                Yours，Li Hua参考范文Dear Tom，How are you doing？I wonder if you could sell some Chinese knots for me.I made them myself with red silk threads，cloth and other materials.These knots look really beautiful in the shape of a diamond，about 5 inches long and 4 inches wide.In China，they stand for friendship，love and good luck.People can either give them as gifts to friends or hang them in their houses or in their cars，which is likely to give people an extraordinary experience.They are only 12 US dollars each.If anyone wants to know more about the knots，let them write to me.Also，do let me know if you need further information.Thank you.Yours，Li Hua
