Then, it declined steadily in the following 时间段, bottoming out at 数据 at 时间点. 重点句型 有波动但总体上升，之后下降 From then on, it generally maintained an upward trend until the peak( about 数据) was reached at 时间点, in spite of some small fluctuations. However, after that there was a slump in the percentage, and it continued until 时间点 when the number reached the bottom of 数据. 重点句型 先上升后下降，再上升最后下降 It can be seen that 对象 starts from数据 at 时间点 , and is followed by a steady rise to approximately 数据 at时间点 . However, from then on, the number 趋势 （v.） for the next 时间段to hit the bottom of 数据. After that, the 对象 is on a steady rise until 时间点, when the peak of the day is reached, about 数据. The last 时间段 of the day, not surprisingly, witness a sharp decrease in 对象 to 数据. 重点句型 先下降再上升，之后下降并持平 However, 对象 first experiences a gradual decline from数据 at 时间点 to 数据 at 时间点, which is the lowest in the day, and then a steady climb, back to its peak of 数据 at 时间点. In contrast to 比较的对象, 对象 decrease slightly and almost level out for most of the evening, with a peak (nearly 数据) at 时间点. Sales of Product A in Different Regions of the USATons 先上升后下降，再上升最后下降 It can be seen that the sales of Product A in the East of the US starts from 20 tons in the first season , and is followed by a significant rise to the peak, approximately 80 tons, in the next season. However, from then on, the number descends for the next season to hit the low point of 50 tons. After that, the sales is on a steady rise until the end of the year, with the figure reaching 60 tons. The first season of the next year, not surprisingly, witness a sharp decrease in sales to 20 tons. 先下降再上升，之后下降并持平 However, the sales in the Western part of the US first experiences a gradual decline of 5 tons from the first season to the second, and then a steady climb, back to its peak of about 60 tons in the third season. In contrast to the sales in the East, the number in the West decreases slightly to reach the lowest ( above 30 tons) and almost levels out for the rest of the year. 有波动但总体上升 The sales in the South of the US generally maintained an upward trend until the peak( about 80 tons) was reached in the first season next year, in spite of some small fluctuations. 三线图 The graph below shows the proportion of the population aged 65 and over between 1940 and 2040 in three different countries.剑5P29三线图写法 方法1 分段描述，以不同时间为段 方法2 找相似的2条图为一组描述，其余的单独描述 方法3 分别描述三条线 分段描述 首段 总趋势 第二段 1940-the present time 第三段 present time - 2040同义替换 population aged 65 and over aging population elderly people older people aged 65 and more/ aboveThe graph below shows the proportion of the population aged 65 and over between 1940 and 2040 in three different countries.P1 The graph shows the increase in the ageing population in Japan, Sweden and the USA. It indicates that the percentage of elderly people (aged 65 and over) in all three countries is expected to increase to almost 25% of the respective populations by the year 2040. （总趋势）P2 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 2.5% for much of this period, before rising to almost 5% again at the present time. P3 In spite of some fluctuation in the expected percentages, the proportion of older people will probably continue to increase in the next two decades in the three countries. A more dramatic rise is predicted between 2030 and 2040 in Japan, by which time it is thought that the proportion of elderly people will be similar in the three countries. 方法2 第一步： 时态-过去时 现在时 将来时 第二步： 观察规律 1. 都大幅上升 2. 美国和瑞典前50年基本完全相同 3. 90年后，美国和瑞典分道扬镳，应该分别来写 4. 日本的变化完全不同，应该单独占一段 第三步：首尾各一段，美国和瑞典一段，日本一段，共四段 The line graph shows the proportion of people aged 65 and more in Japan, Sweden, and the USA from 1940 and the expected proportion to 2040.Sweden& USA From 1940 to 1990, the proportions of ageing population in the USA and Sweden were similar and followed the same trend.(总) In 1940, the figures stood at 9% in the USA and 7% in Sweden. （分）Thereafter, the percentage grew to 15% and 14% respectively in 1980, before falling to 14% and 13% each in 1990. The two countries follow different pattern after that. After a leveling off, the percentage of elderly people in the USA is predicted to climb to about 23% in 2040. However, in Sweden, in spite of some fluctuation, there will be increasingly more people aged 65 and over until 2040. Japan The situation in Japan differs significantly. The situation in Japan differs considerably(总). After a slight descend in the percentage of elderly people between 1940(5%) to 1960(3%), the figure remained steady until 1985, where upon it began to climb. This rise is projected to continue until around 2030, when the proportion of Japanese aged 65 and over is expected to reach 10%. Thereafter, within just a few years, the proportion is forecasted to rise dramatically to 25%, with a less dramatic rise to 27% in 2040. Overall, there are predicated to be around 25% population in all three countries exceeding 65 years old by 2040.Exercise The graph below gives information about water use worldwide.Global Water Use by Sector The 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 km3 in 1900 to around 3000 km3 in the year 2000. Water used in the industrial and domestic sectors also increased, but consumption was minimal until mid-century. From 1950 onwards, industrial use grew steadily to just over 1000 km3, while domestic use rose more slowly to only 300 km3, both far below the levels of consumption by agriculture. 四线图 The graph below shows the consumption of fish and some different kinds of meat in a European country between 1979 and 2004. 剑7P53同义替换 consumption be consumed be eaten popular/ popularity分组描述 增长的 Chicken 减少的 Beef Lamb 平稳的 Fish分组描述 首段： 概述 第二段： 起点 第三段： 下降 第四段：上升 第五段： 总趋势The graph below shows the consumption of fish and some different kinds of meat in a European country between 1979 and 2004. P1 The graph illustrates changes in the amounts of beef, lamb, chicken and fish consumed in a particular European country between 1979 and 2004.P2 In 1979 beef was by far the most popular of these foods, with about 225 grams consumed per person per week. Lamb and chicken were eaten in similar quantities (around 150 grams), while much less fish was consumed (just over 50 grams).P3 However, during this 25-year period the consumption of beef and lamb fell dramatically to approximately 100 grams and 55 grams respectively. The consumption of fish also declined, but much less significantly to just below 50 grams, so although it remained the least popular food, consumption levels were the most stable.P4 The consumption of chicken, on the other hand, showed an upward trend, overtaking that of lamb in 1980 and that of beef in 1989. By 2004 it had soared to almost 250 grams per person per week. overtake=exceed/ outweigh/ outnumber/ more than P5 Overall, the graph shows how the consumption of chicken increased dramatically while the popularity of these other foods decreased over the period.多线图解题要点 1. 合并趋势和数据相似的线 2. 趋势不同的单独分一段 3. 多使用比较性的衔接 4. 注意总结趋势的异同 follow the similar / same trend/ pattern. rise to and respectively. each accounting for and . . differs significantly.
