13、变化趋势进行比较, 将图表中相似的趋势分别捏合成一段叙述比较图表中相对比的两个部分的所有比例得出一个总体结论第二句以后:详细解释这一总体趋势As can be seen from the bar chart, in the groups of employed full-time, unemployed and retired, males enjoyed more leisure time than females.

15、bout women are given. To be more precise, female part-timers and housewives had 39and 52 hours of leisure time respectively. 时间变化型(time-change)的写法与表达方式 以line graph为例,因为这种题型最能体现时间变化型的特征。从实际的考题中可以总结出Line graph中的线可以分为:复杂的线、简单的线以及相似的线。考生只要学会这三种线的写法,那线图就得心应手。复杂的线就是变化起伏较多的线,其写法就是根据变化的趋势分为几段进行描述。如下图:It is
16、clear from the line graph that the birth rate in China increased steadily from about 10 percent in 1920 to just over 15 percent in 1935, followed by a sharp decline to nearly 5 percent in 1940, which remained stable until 1945. After that, it jumped to the peak of almost 20 percent in 1950, when it
17、plunged again to roughly 8 percent in 1955. Since then, it continued to fall until 2000. 经典:多临摹 (将复杂的线分为几段,写作的重点就是如何衔接不同段。注意斜体字,这些都是线图的衔接方法。)简单的线即变化较小或者只有一种趋势。相似的线即与题中另外一条线相似的线。Visits to and from UK (in millions)It is clear from the line graph that the visits abroad by the UK residents showed an upw
18、ard trend from about 15 million in 1979 to nearly 55 million in 1999. (简单线的写法:运用特定的句式)A similar pattern was repeated for the visits to the UK by foreigners, except that the number was within the range of 10 million in 1979 and just under 30 million in 1999.(相似线的写法:运用特定的句式) 经典:多临摹第二篇 曲线图写作要点:1曲线图和柱状图
19、都是动态图,解题的切入点在于描述趋势。2在第二段的开头部分对整个曲线进行一个阶段式的总分类,使写作层次清晰,同时也方便考官阅卷。接下来再分类描述每个阶段的specific trend,同时导入数据作为分类的依据。3趋势说明。即,对曲线的连续变化进行说明,如上升、下降、波动、持平。以时间为比较基础的应抓住“变化”:上升、下降、或是波动。题中对两个或两个以上的变量进行描述时应在此基础上进行比较,如变量多于两个应进行分类或有侧重的比较。4极点说明。即对图表中最高的、最低的点单独进行说明。不以时间为比较基础的应注意对极点的描述。5交点说明。即对图表当中多根曲线的交点进行对比说明。6不要不做任何说明就机
20、械地导入数据,这不符合雅思的考试目的。范文You should spend about 20 minutes on this task.The graph and table below give information about water use worldwide and water consumption in two different countries.Summarise the information by selecting and reporting the main features, and make comparisons where relevant.Write
21、at least 150 wordsThe graph shows how the amount of water used worldwide changed between 1900 and 2000.Throughout the century, the largest quantity of water was used for agricultural Purposes, and this increased dramatically from about 500 km to around 3,000 km in the year 2000. Water used in the in
22、dustrial and domestic sectors also increased, but consumption was minimal until mid-century. From 1950 onwards, industrial use grew steadily to just over 1,000 km, while domestic use rose more slowly to only 300 km, both far below the levels of consumption by agriculture.The table illustrates the di
23、fferences in agriculture consumption in some areas of the world by contrasting the amount of irrigated land in Brazil (26,500 km) with that in the D.R.C. (100 km). This means that a huge amount of water is used in agriculture in Brazil, and this is reflected in the figures for water consumption per
24、person: 359 m compared with only 8 m in the Congo. With a population of 176 million, the figures for Brazil indicate how high agriculture water consumption can be in some countries.(180 words)1.png (6.19 KB)2010-6-17 10:59The three graphs of wheat exports each show a quite different pattern between
25、1985 and 1990. Exports from Australia declined over the five-year period, while the Canadian market fluctuated considerably, and the European Community showed an increase.In 1985, Australia exported about 15 millions of tonnes of wheat and the following year the number increased by one million tonne
26、s to 16 million. After that, however, there was a gradual decline until 1989 and 1990 when it stabilised at about 11 million tonnes. Over the same period, the amount of Canadian exports varied greatly. It started at 19 million tonnes in 1985, reached a peak in 1988 of 24 million, dropped dramaticall
27、y in 1989 to 14 million tonnes and then climbed back to 19 million in 1990. Seventeen million tonnes were exported from the European Community in 1985, but this decreased to 14 million tonnes in 1986 and then rose to 15 million in 1987 and 1988 before increasing once more to 20 million in 1990.(165
28、words) 经典:Dropped siligtly to around 14 million tonnes before reaching it peak at 25 million in 1988例文-4The line graph indicates the changes of energy demand and the energy available from fossil fuels in Freedonia for 20 years to 2005.According to the line graph, the amount fo energy available from
29、fossil fuels fluctuated during the twenty years. It increased significantly from approximately 350 billion megajoules in 1985 to 650 billion in 1995, which was its peak. But after that it dropped sharply and is expected to be 250 million in 2000 and keep stable until to 2005.However, the demand for energy shows a opposite trend. Between 1985 and 1990, the demand for energy decreased gradually from 500 million to nearly 200 million. There was little change in this number during the next five years. Since 1995, it increased to less than 400 million in 2000 and is
