   分析：

   1. 写作时首段应是命题的改写

   2. 主体段应描写大的特征或对大趋势的概括（关键数据支持）

   3. 关键数据即起点终点坐标，*大*小值，偶尔会用交点坐标，部分特征拐点坐标。

   注意点：

   2. 分词和比较结构的使用

   3. 从句的使用

   4. 整篇文章万万不可主观推理分析，否则扣分

   Example:

   （首段）The three lines in the chart each show the changes in the proportion of the elderly people to the population of the USA, Sweden and Japan from 1940 till today. Also the chart gives predicted date for the trends.

   （主体段）Since 1940, the proportion in the USA has been slightly higher than that in Sweden at any given time, while that in Japan was always the smallest. Specially, the figures for the three countries in 1940 were 9%, 7%, 5% respectively. The changes in the proportion in the USA and Sweden are featured mainly by steady increase although since 1980 the USA experienced somewhat declines. By contrast Japan did not see increase substantially, sending it to a peak of 5% in 2007, the same as in 1940. According to the prediction since 2000, the upward trends will have been obvious in the three countries, but in Japan will soar at the fastest speed. Till/By 2040 the figure will have reached 27%, compared with 25% in the USA and 23% in Sweden.

   另一篇范文，主要展示*值的表达：

   In the term of the length of the Underground Railway System (URS), that in London ranks first among the six in that it reaches 394km, almost 36 times longer than that in Kyoto, the shortest. The second longest is in Paris (199km).

   Focusing on the open date, we see that once again London URS was strikingly earlier than all other counterparts. Put it accurately, London opened the URS as early as in1863, 37 years earlier than that in Paris. By contrast, the youngest is LA who did not start to run URS until 2001.

   说明文注重语言的流畅，简洁。在图表作文中，不追求词藻的华丽，只追求表达的清楚。

   注意点：

   1. 没有必要写出每条信息，要辨别关键特征

   2. 段落划分要合理（得分点）

   3. 衔接和过渡词很重要

   Example: 剑五P75

   To be located in the town centre, S2 is in the town centre, a non-traffic zone. As result, it is only accessible by the railway whereas the main roads are unavailable. Moreover, it is hemmed out the houses, meaning it’s convenient for the dweller s to do some shopping. In addition, it is closer to the south industry but far away from the north.

   Unlike S2, S1 will be set in the countryside, where both the railway and main roads are ready. But the 44000 people from Bransdon and Crandson find it not easy to reach S1, although it is connected by the railway with Crandson. Furthermore, this site is far away from the two industry areas. However, it is convenient for those who live in Hindo.

   To sum up, the two sites are different in many aspects/ways.

   小结：

   1. 柱状图可变成线性图；

   2. 饼状图可变成表格图（表格题中，在对象的旁边标识出上升，下降，或有变化的箭头，之后，将同类上升的写一段，下降的写一段，不稳定的单列一段）；
