考研英语二图表作文写作方法和模板非常全有作用

考研英语二_图表作文写作方法和模板图表作文一第一节图表作文的类型图表作文可分为两大类：表作文和图作文;表作文表格Table可以使大量数据系统化,便于阅读、比较;表格常由标题Title、表头Boxhead表格的第一行、侧目Stub表格左边的第一列和主体Body 部分表格的其余部分等部分组成;如下表：用表格表达的信息具体准确,而且表格中的各项均按一定规律排列;阅读表格时要注意找出表格中各个项目的相互关系,表格中各个项目的变化规律;例如,上面的表格中的数字说明,和1978年相比,1983年大学入学的人数在增加,而小学的入学人数在减少;搞清楚这些变化规律也就读懂了表格的内容;图作文图作文又可分为三种：圆形图作文、曲线图作文和条状图作文;1 圆形图作文圆形图Pie chart也称为饼状图或圆面分割图;圆形图因为比较形象和直观,各部分空间大小差别容易分辨,所以常用来表示总量和各分量之间的百分比关系;整个圆表示总量,楔形块表示分量;有时圆形图还有数值表,两者结合可把各分量表示得更准确、清楚;例如：This is a pie chart of the average weekly expenditure of a family in Great Britain. As can be see from the chart, the main expenditureof an average British family is spent on food, which accounts for 25% of its total expenditure. The next two significant expending items are transport and housing, which are 15% and 12% respectively. If we take into account clothing and footwear, which makes up 10%, the four essentials of life, that is, food, transport, housing, and clothing and footwear, amount to 62% of the total expenditure.2 曲线图作文曲线图Line graph也称为线性图或坐标图;曲线图最适合表示两个变量之间关系的发展过程和趋势;一般来说,曲线所呈现的形状比某一点所代表的变量的值更有意义;曲线图有横轴和纵轴;一般先看横轴所代表的数量或时间等,然后再看纵轴所显示的意义;同时必须找出线条所反映的最高或最低的变化;例如：这个曲线图的横轴代表1990年的不同的月份,纵轴代表交通事故的数量;从交通事故曲线图上可知,前八个月的交通事故的数量有升有降;曲线图在八月份升到了最高点39,此后一直呈下降的趋势,十二月份降到了最低点16;可见,1990年的交通事故的数量总体上呈下降的趋势;3 条形图作文条形图Bar graph也称为立柱图或圆柱图;条形图由宽度相同但长度不同的条块代表不同的量;当要比较几个项目或量时,常用不同颜色来区分;条形图主要用来表示：1同一项目在不同时间的量;2同一时间不同项目的量;阅读条形图时,要先看图例,再看横轴、纵横各代表什么量,每一个刻度所代表的值是多少,最后找出图中各长条所表示的数据及各长条间的相互关系;例如：左边的条形图的横轴代表时间,纵轴代表期望寿命Life Expectancy,这一条形图想要体现的是同一项目期望寿命在不同时间的量;右边的条形图的横轴也是代表时间,纵轴是代表婴儿的死亡率Infant Mortality,这一条形图想要体现的也是同一项目婴儿的死亡率在不同时间的量;左边的条形图表明1990年的人均期望寿命比1960年的人均期望寿命长20岁,而1990年的婴儿死亡率比1960年的婴儿死亡率下降了50%;第二节图表作文的出题形式例1 题目：Changes in People’s DietStudy the following table carefully and your composition must be based on the information given in the table.

Study the following table carefully and your composition must be based on the information given in the table. Write three paragraphs to:1. state the changes in people’s diet 饮食in the past five years;2. give possible reasons for the changes;3. draw your own conclusions.You should quote as few figures as possible.⑴As is shown in the table, there have been great changes in people's diet between 1986 and 1990. ⑵From the table, we can find that grain, formerly the main food of most Chinese people, is now playing a less important role in people's diet. ⑶And the same goes for fruit and vegetables. ⑷On the other hand, the consumption of high-nutrition food such milk and meat has increased rapidly.⑸What has caused these changes There are mainly three reasons 主题句. 6 First, people are much wealthier than before. 7 With higher income, they can afford to buy nutritious foods. 8 Second, people have realized the importance of a balanced diet to their health. 9 Lack of certain amount of meat or milk, for example, will result in poor health. 10 Finally, owing to the economic reform, meat and milk, which were scarce in the past, are produced in large quantities.11 Although milk and meat are important to one's health, eating too much rich food may result in obesity and may other diseases. 12Therefore, people should not only eat a lot of milk and meat, but also enough grain, fruit and vegetable for the sake of their health.图表作文二一、图表作文写作常识1、图形种类及概述法：泛指一份数据图表：a data

Study the following graphs carefully and write an essay in at least 150 words. B. Your essay must be written clearly on the ANSWER SHEET II. C. Your essay should cover these three points:1. effect of the country’s growing human population on its wildlife2. possible reason for the effect3. your suggestion for wildlife protection段落类型分析第一段第二段第三段图画/图表描述段原因阐释段建议措施段参考范文一From these graphs, we can draw a conclusion that, with the growth of human population, the number of species has decreased rapidly in America, and some species have even vanished from our planet. There are numerous reasons accounting for the phenomenon and I would like to explore a few of the most important ones here. Above all, as the human population grows rapidly, a growing number ofpeople came to live where some wild species have been living. Then these species have to move to other places. Some of them probably can not adapt to the new environment and die. In addition, although many people look on the wildlife as their friends, some people may not think so. They catch a lot of wild animals and sell them in order to get more money. Consequently, the natural balance and the ecologic environment are destroyed. The clear cutting has become increasingly serious. So some of the wildlife become homeless and extinct.In order to protect the wildlife, I have some suggestions. First, the governments should make laws to prevent them from being caught and killed. Second, the governments should educate people to love nature and protect it. Third, as for ourselves, we should take practical actions to protect our living environment. 210 words参考范文二The two charts show that the increase in the . population has been accompanied by a corresponding decline in the number of wildlife species. Far too many species have been lost already. This poses a danger to the ecological balance.As the human population expands, wild animals in mounting numbers are hunted for food, or because they are thought to present a threat to man. But studies show that one of the primary causes ofthe disappearance of wildlife is pollution, which is one of the consequences of population growth and economic development. This makes us wonder if men are able to share this planet in harmony with other life forms.In my opinion, it is imperative for us to take steps to reverse the disturbing trend illustrated in the charts. One measure would be to forbid the building of cities in areas where wild life is threatened with extinction. But, more importantly, men must learn to stop polluting the environment, or he himself will be extinct. 167 words参考范文三As is seen from the two graphs, it is clear that with the rapid growth of . population from 1800 to 1990, the number of its wildlife species no longer existing soared during the same period. Naturally, we can draw the conclusion that the sharp decline of wildlife species resulted from the population growth.Several reasons may account for this phenomenon. To begin with, as the population grows, people consume much more natural resources. Second, with the increase of human activities, modern people take up more and more space which exerts a great influence on other species. Finally, the problem of pollution becomes more and more serious with the development of modern industry. More and more animals have to adapt themselves to the decaying environment ormove to a totally different place, but not all of them are fortunate enough to survive the changes.Solving this problem calls for, above all, the government’s efforts to control population growth, to decrease industrial pollution and to enhance the laws to forbid wildlife hunting. Moreover, common citizens should be aware of this ecological crisis and take on the responsibility of wildlife protection. In a word, only when the government and the common people make joint efforts can we hope to find a satisfactory solution to this problem. 216 words作文2图略The line graph illustrates how the number of people using a London underground station fluctuates over the course of 16 hours 6am to 10pm. As we can see from the graph, at 6am the number of people at the station stands at only 100. The number shoots up over the next two hours, peaking at 400 at 8am. Then the number descends drastically for two hours, bottoming out at 180 at 10am. The period between 10o'clock and 12o'clock witnesses a moderate growth in the number of people in the station, with the number reaching 280 at midday. Numbers in the following two hours stabilize at just under 300 people. Then the number plummets to only 100 from 2pm to 4pm. Then the next two hours see a dramatic rise again, with 6pm registering 380 people. After 6pm, the number dips again,reaching the lowest point of 130 at 8pm. The period from 8pm to 10pm experiences a slight rise, but then the number of people declines again from 180 at 9pm to 135 at 10pm. This line graph clearly demonstrates that rush hours in the early morning and the early evening are periods when the station is used by the most people.作文3The diagram illustrates in four stages the recovery of the forests in Yellowstone National Park after a devastating forest fire. In the first picture, while the old forests still exist, they drop bad wood to the soil under them, which renders the soil more fertile. Then lightning and fire strike, destroying the forests completely. And the growth of new forests starts right at this point. The second picture demonstrates that in the first 50 years after the devastating fire, saplings grow in build while descend in overall number. In the next two centuries, the young trees continue to thrive in Yellowstone, because of the fertile soil and the ample sunlight. Then, three hundred years after the fire, the number of trees decline to roughly the same as the old forests. These five pictures show us that it takes as long as three centuries for a destroyed forest to fully recover. Further, they vividly explain to us the natural law of "survival of the fittest". The number of trees that a region can support is not limitless, which means the forests on earthwill not be an inexhaustible resource.作文4The table below gives information about changes in modes of travel in England between 1985 and the information by selecting and reporting the main features, and make comparisons where relevant.范文1The table indicates the number of miles by the average English person in 1985 and 2000, using various means of transport.The number of miles walked, cycled and travelled by local bus all decreased. Of these, the number of miles travelled by local bus decreased the most, from 429 miles in 1985 to 274 miles in 2000. The number of miles travelled by car, long distance bus, train and taxi all increased. The number of miles driven by car was 3,199 in 1985 and rose by 50% to 4,806 in 2000. The number of miles travelled by long distance bus more than doubled from 54 miles 1985to 124 miles 2000. The number of miles driven by taxi trebled from 13 miles 1985 to 42 miles 2000. The use of other, unspecified, forms of transport also increased.Overall, the number of miles travelled by the average English person rose from 4,740 miles in 1985 to 6,475 miles in 2000, with the increase of cars accounting for almost all of that increase. 173 words范文2The table demonstrates how different modes of travel changed in England in 15 years spanning from 1985 to 2000. In general, the modes are classified into two kinds in terms of average miles travelled per person per year: one enjoyed rising popularity while the other decreasing.The travel modes which gained popularity in the period included cars, long distance buses, trains, taxis and others. Cars remained top among the modes in the 15 years, with its average miles increasing considerably from 3,199 in 1985 to 4,806 in 2000. Long distance buses and taxis seemed to be warmly welcomed by travelers, so average miles travelled in the two modes almost tripled.Travels by walking, bicycles and local buses lost travelers’favor in the one and a half decade. Average travelling distance by local buses suffered the biggest decrease, dropping from 429 to 274, whilst the number of miles by walking and bikes fell mildly from 255 to 237 and from 51 to 41 respectively. Despite the decreases, however, the total miles travelled grew from 4,740 to 6,475.In brief, the total travelling distance in the country grew in 15 years when cars, long distance buses, trains, taxis and other modes of travel were more popular and walking, bicycling and localtransportation less popular. 212 words作文5Directions: For this part, you are allowed 30 minutes to write a composition of no less than 100 words on Income Sources between Chinese and American Students. Study the following table carefully and your composition must be based on the in formation given in the table. Write three paragraphs to:1. Describe the differences of the income sources between Chinese and American students.2. Analyze possible reasons for these differences.3. Predicate future tendency.Source of income Percentage of Total Income_________________________________________________________________________ _____Parents Part-time job Fellowship or ScholarshipAmerican students 50% 35% 15%Chinese students 90% 5% 5%_________________________________________________________________________ ______范文: Income Sources Between Chinese Students and American StudentsIncome sources of Chinese students are quite different from those of American students. In China, students get 90% of their money from their parents while in America, only 50% of students` money is provided by parents. In addition, Chinese students earn only 5% of their money from part time jobs and 5% from fellowship or scholarship while income from these two resources for American students takes up 35% and 15% respectively of their total income.I think there are probably three reasons for their differences. First, because of the influence of different social and family values, Chinese students have formed the habit of asking for money from their parents while American students have developed more sense of being financially independent. Second, most Chinese parents devote too much care to their children and they would rather save up to afford their children’s education rather than encourage them to take part-time jobs. But in America, many parents pay more attention to developing the students ability of self-reliance, so they encourage their children to find part-time job to earn some money by themselves. Third, since America is more developed than China, it is relatively easy for students to find part-time jobs. In China, such opportunities are rather rare.I believe with the development of China, more and more Chinese students will realize and pay more attention to the necessity of self-dependence. In addition, more and more opportunities will be provided for them to take part-time jobs. So more students will go out of the ivory tower to broaden their knowledge and to become the master of their own lives.作文6For this part, you are allowed thirty minutes to write a composition on the topic: Student Use of Computers. You should write at least 120 words, and base your composition on the chart and the outline given below:1.上图所示为1990年、1995年、2000年某大学生使用计算机的情况,请描述其变化；2.请说明发生这些变化的原因可从计算机的用途、价格或社会发展等方面加以说明；3.你认为目前大学生在计算机使用中有什么困难或问题;范文: Student Use of Computer Since 1990, there has been tremendous growth in the use of computers by students. While in 1990, the average number of hours a student spent on the computer was about one hour per week, this number grew to nearly four hours per week by 1995, and to approximately 20 hours per week by the year 2000.This significant growth in the use of computers by students in the 1990’s can be attributed to several factors, including widespread usage, lower prices, and technological and social developments. Nowadays, computers are widely used by students for word processing, book keeping, multimedia presentations, and access to the Internet for both research and communications. Additionally, since 1990, due to competition and technological advances, computer hardware and software prices, as well as Internet usage charges have dropped significantly. Finally, technological developments and changes in social habits in the 1990’s have played a major role in this tremendous growth in the use of computers. Today’s society relies heavily on computers for immediate access to the news and for entertainment, including, listening to music, watching movies and sport events, and playing computer games. While computers are of great assistance to the students, and therefore, are indispensable tools, they also pose some challenges. The biggest challenge that many students face is discipline in the use of this powerful device. That is, students need to have the discipline of not allowing themselves to be lured by the entertaining aspects of this wonderful tool—aspects that can result in addiction to computer games or viewing of undesirable material on the Internet. That is to say, students need to use this powerful tool with great wisdom作文7The graphs below show the age structure of a European country from 1901 to 1981 and a prediction for 2021. Summarize the information by selecting and reporting the main features, and make comparisons where relevant. You should write at least 150 words. Sample AnswerThe graphs compare the population makeup of one European country every forty years from 1901 to 1981, and the estimated number in 2021. There was a huge increase in the number of people in this country from 38,225,000 in 1901 to 67,180,000 eighty years later, and this upward trend is expected to last through to the year 2021, when the population is estimated at 87,658,000, more than double the 1901 figure.In 1901 and 1941, the population structure in this country was completely the same, with an overwhelming majority of its population 95% below 65, 4% between65 and 85 and only 1% over 85 years old.However, the year 1981 sawa sharp increase in the percentage of the elderly. Altogether, they made up 17% of the total population, whereas the projection for the year 2021 shows that they will continue to grow but less dramatically to 20% of the total population 15% for 65-85-year-olds and 5% for over-85-year-olds. In summary, changes are taking place not only in the number of people but also in the ages of the people who make up the population in this European country, indicating it is advancing。
