图表作文讲解2:柱状图和饼状图学生面授老师时间本次课时雅思写作第二课时教学思路1.作文简介、写作技巧2.实例讲解3.分析总结4.课后作业教学目标柱状图、饼状图知识点讲解基本特征和写作方法实例分析讲解重点写作技巧讲解范文学习柱状图和饼状图写作方法备考资料剑桥IELTS4-8教学详细内容:一、 写作技巧详解1. 柱状图特点 柱状图是动态图表,切入点是描述趋势。 柱状图写作注重“比较”(找出similarity)和“对比”(找出difference),也就是说需要横向总结所有柱状图表的共性特征,也要分别描写各个柱子的个性特征。 两种写作方式:其一是对不同时间段内的数据进行比较,适合于数据代表的物体较少且时间界限明确的情况。另外是对单独数据的全程描述,适合于描述数据对象很多且时间划定不清晰的情况。2. 饼状图特点饼形图与柱形图或者线形图所截然不同的是它没有了横轴与纵轴,而以饼形的分割来表示百分比,可以依照三步审题分析法来进行观察: 观察共有几张饼状图,以及它们之间的关系是什么(一般说来,雅思图表题中极少见到单饼图); 观察每张饼状图中有哪几个区域,以及各个区域分别代表什么; 观察单个饼状图中各区域间的百分比差异,以及相同区域在各个饼状图间的百分比的比较或发展。饼状图是所有图表题中最好写的一种,唯一值得注意的地方在于如何丰富百分比的表达 和“占”的表达,要采取多样性的表达,如25%=a quarter of, 50%=half of, 50%=a/the majority of.描写饼状图中的比例构成就是饼状图图表作文的重点,但也应注意,这种描述并不是对图形的简单重复,对各项数据比例的描述应建立在归纳整理的基础上有条理地进行。学生不仅要善于找数据,更重要的是要善于从数据或比例中升华出来,找到规律和本质。常用词汇、句型及模板1. 柱状图1)倍数的表达 今年的产量是去年产量的两倍 The output this year is two times(twice) more than last years.

It consists of six segments, the largest one representing _, which account for 26% of the total. _ takes up 21%, becoming the second largest._. The rest proportions, 15% of all, constituting 5% and 10% respectively.From the chart it can be seen clearly that _.二、实例分析分析思路:1. 第一幅柱状图的描述单位是百万,即人数;第二幅则是百分比。2. 第二幅柱状图仅显示了1970年和2000年的信息,而第一幅柱状图显示了1970、1980、1990、2000年的信息。3. 由第一幅柱状图可以看出,从1980年到2000年,结婚人数和离婚人数的变化趋势相似。4. 从第二幅图可以看出,在2000年,结婚和寡居的成年人的比例有所降低而从未结婚过和离婚的比例则有所上升。范文分析One chartshows the number of marriages and divorces in the USA in 1970, 1980, 1990 and 2000.The othershows the marital status of adult Americans in 1970 and 2000.首段概述图表信息,对题目进行改写,注意动词的用法和时态。 描述类的常用词有:show/describe/illustrate/demonstrate/indicate; 首段概括图表信息的时候都用一般现在时; 改写题目的时候注意扩充时间地点等细节。The first chartindicates that the number of marriages in America(2.5 million) was the same in 1970 and 1980.
