1、Welcome to IELTS WRITING段落段落句数句数作用作用开头段12句改写原题主体段11+X句每个主体段第一句总体概括X句具体介绍数字主体段N结尾段12句第一句介绍总数第二句话做结论双双线图特点：两特点：两线变化化趋势类似；两似；两线之之间变化差化差别大，可能整体大，可能整体趋势或某或某 段段趋势相反。相反。The graph below shows radio and television audiences throughout the day in 1992.双双线图1.开开头段：段：与写一条曲线方法相同，即改写题目The graph below shows radio a

4、re more radio audiences,while after 1pm more people turned to television.双双线图Step2.两线各成一段，各段同单线写法。注意段间过渡句过渡句：渡句：Similarly,Likewise,In comparison,By/In contrast,On the other hand,Turning toAs for.When it comes to.,however,the picture was different.However,the story was different in.双双线图Step2.两线各成一段，各

5、段同单线写法。注意段间过渡句The data indicated that radio listeners increased substantially before 8 am,when the percentage reached to a peak of 27%.Then,it declined steadily in the following 20 hours,bottoming out at 2%at 4 am of the next day.The period from 4 am to 6 am saw another slight rise to 4%in radio lis

6、teners.双双线图Step2.两线各成一段，各段同单线写法。注意段间过渡句As for TV viewers,the period from 6 am to 8:30 am saw a slight increase,when there was a leveling off at 8%until 10 am.From then on,it generally maintained a sharp upward trend until the peak(45%)was reached at 8 pm,in spite of some small fluctuations.However,t

7、here was a slump thereafter in the percentage,which reached the bottom of 3%at 3 am,when there was a slight rise afterwards.双双线图3.结尾段：尾段：总结两条曲线的共同点和不同点The general trend was that the percentage of both radio and television audiences rose first and then decreased,while the total number of the latter w

8、as bigger than the former.In addition,the prime time for radio and television was 8 am and 8 pm respectively.Tips：总结趋势：相似与不同多多线图The graph below shows the proportion of the population aged 65 and over between 1940 and2040 in three different countries.Summarize the information by selecting and reporti

9、ng the main features,and make comparisons where relevant.多多线图线图的的难点在于点在于线条条变化曲折，如果完全描述，不但化曲折，如果完全描述，不但过于于琐碎，而且意碎，而且意义不大，所以不大，所以线条的条的变化情况化情况需要取舍需要取舍，这是是线图的的难点。点。图表中表中最高点最高点和和最低点最低点都要都要单独独说明；明；对图表中多条曲表中多条曲线的的交叉点交叉点进行行对比。比。多多线图第一步：确定X轴和Y轴第二步：分析图表X1 应当特别注意到时间是1940-2040，也就是本图表包括什么时态？临界点在哪里？多多线图X2 为Japan

10、时，Y 轴变化情况化情况起点是 5%，终点是27%，涨幅是22%；跨越时间临界点的变化时继续上涨；变化趋势：从起点 1940-过了2000 年，呈一个先下降后升高的趋势，两段终点为均为5%；之后缓慢升高，2030 年达到10%；2030-2040 年猛增，终点是27%。多多线图X2 为Sweden 时，Y 轴变化情况化情况起点是 7%，终点是25%多一点，涨幅18%；跨越时间临界点的变化是上涨，但是之后有个小的下降；变化趋势：持续上涨，整个过程只有1980-1990 和2010-2030 这两个区段稍微下降。多多线图X2 为USA时，Y 轴的的变化情况化情况起点为 9%，终点是23%，涨幅为1

11、4%；跨越时间临界点的变化为持平然后上涨；变化趋势：持续上涨，只是1982-2020 为持平状态。多多线图X1 为1940 时日本 5%，瑞典7%，美国9%X1 为1940 到到临界点界点时瑞典和美国上升，均达到 15%左右；而日本先稍微下降而后上升，1940 和临界点的结果持平在5%X1 为临界点到界点到终点点2040瑞典和美国继续上升，最后终点在 25%左右；而日本继续上升，特别是2030 后猛升，最后超越瑞典和美国，终点值最高27%。多多线图第三步：确定框架有 2个X 时，就会有2个文章发展框架。如本例X2（瑞典、日本、美国），即描述瑞典的变化趋势，再描述美国的，最后描述日本的；同样可以

12、X1 为主框架，即描述三国起点的状况，再是起点到临界点的状况，最后是临界点到终点的状况。两种逻辑框架均可以，只是要特别注意，分析部分的重要信息应当不能有遗漏，从框架的信息必须安排好。多多线图The graph shows the increase(直奔主旨)in the ageing population in Japan,Sweden and the USA.It indicates that the percentage of elderly people in all three countries is expected to increase to almost 25%of the

13、respective populations by the year 2040.(对主旨进行进一步说明)开开头段：段：多多线图In 1940 the proportion of people aged 65 or more stood at only 5%in Japan,approximately 7%in Sweden and 9%in the US.However,while the figures for the Western countries grew to about 15%in around 1990,the figure for Japan dipped to only 2

14、.5%for much of this period,before rising to almost 5%again at the present time.主体段：主体段：多多线图In spite of some fluctuations in the expected percentages,the proportion of elderly people will probably continue to increase in the next two decades in the three countries.A more dramatic rise is predicted be

15、tween 2030 and 2040 in Japan,by which time it is thought that the proportion of elderly people will be similar in the three countries.主体段：主体段：Tips:注意临界点前后时态的区别使用多多线图Overall,the line graph displays a general increasing trend in the number of elderly people in all the three countries,with the number being around 25%expected in 2040.结尾段：尾段：多多线图线图总结：u线性图的整体趋势的变化进行描述，尤其是对于多线图，不在于具体的趋势变化；u对于极致点的描述，但是主要针对的单项图或者图形不是很复杂的情况；对于多线图来说很重要的就是归纳和总结；u对于多线图要进行一定的比较和对比。
