第四篇：英語圖表作文

圖表描述專題訓練

（一）這類作文時，注意以下幾點：

第一，審題時，除了要把握好圖表的表層信息外，還要分析圖標的深層含義，如原因、根源、可能的發(fā)展趨勢等。圖表中所提供的說明文字往往是問題的切入點，一定要仔細分析。

第二，描述數(shù)據(jù)時要抓住重點，為中心服務，不必面面俱到，切忌毫無目的地羅

列圖表中的數(shù)據(jù)。如果數(shù)據(jù)較多，抓住圖表中的極端點（如最大或最小、最多或最少，最好或最差）和基本相同進行描述。

第三，主題句應明確，最好放在文章的開頭，這樣會使重點突出，主題明了。

Students Use of Computers

41210

***002Hours

例文：Students Use of Computers 提綱： 1.上圖所示為某校大學生平均每周使用計算機的時間： 1990年（2 hours）, 1995年(4 hours), 2002年(14 hours)，請

描述其變化；2.請說明發(fā)生這些變化的原因（可從計算機的用途、價格或社會發(fā)展等方面加以說明）；

3.你認為目前大學生在計算機使用中有什么困難或問題。參考范文(1)

Student Use of Computers

As is clearly shown in the chart, the number of hours students spent on computers increased from two to four hours per week from 1990 to 1995.Especially, the number rose to about 14 hour per week in 2002.There are three factors leading to the change.To begin with, the price of computers is getting much lower than before so that many students can afford it.In addition, it is very convenient for us to study with the help of computers.For example, e-mails enable us to keep in touch with our teachers and friends.Last but not least, with fast development of the modern society, a computer has become a must for many people.To sum up, low price, convenience and wide use contribute to the increase in the use of computers.As for me, student use of computers is a double-edged sword.On the one hand, it is a good helper in searching for information, drawing pictures, etc.One the other hand, various computer games might distract students from their studies.In brief, computers can serve us well if they are used in the right way.參考范文（2）

Student Use of Computers

As is clearly shown in the chart, the average number of hours a student spent on computers increased from two to four hours per week from 1990 to 1995.Especially, the number reached approximately 14 hour per week in 2002.Why are there such great changes during these days?

There are three factors leading to this phenomenon.Firstly, because of the sharp decline in the price of computers, most college students can afford one.Secondly, the Internet provides access to various kinds of information students are interested in.Finally, playing computer games or surfing online is relaxing.To sum up, low price, easy access to information and wide use make students use computers a lot.As for me, computers do bring convenience to students;however, it is no good fro students to spend too much time chatting online or playing computer games.In brief, in spite of the problems concerning the use of computers, we can’t deny that computers are of more merits than defects.Sample

1Financial Sources of College Students

From the table, we can see clearly that Chinese college students and their American peers rely on different financial sources for their life and study.About 90% of Chinese students get money from their parents.In contrast, only 45% of American students resort to this way.About 40% of American students depend on part-time jobs for income, but only 5% of Chinese students do so.Scholarship is the financial source for 15% of American students, whereas only for 5% of Chinese students.There are several reasons leading to this difference.On the one hand, independence is greatly honored in American society, and students would be proud to depend on themselves.Besides, they have a more flexible schedule so they can have more time to do part-time jobs.On the other hand, some Chinese students take their parents’ financial support for granted.Similarly, parents believe it’s their duty to finance their children’s education

I think with the reform in college education, this tendency in China may be changed.The widespread adoption of credit-system will give Chinese students more time and flexibility to pursue part-time jobs and get more independence from their parents.Also, with the passage of time, both the students’ and the parents’ ideas will change greatly.Thus, more and more Chinese college students are sure to rely on themselves rather

than on their parents for finance.Sample

2Financial Sources of College Students

According to the table, the number of Chinese students who get money from their parents doubles that of American ones, 45% and 90% respectively.But the percentage of American students who depend on part-time jobs is much larger than that of Chinese ones.It can also be seen clearly that scholarship is the financial source for 15% of American students, while only for 5% of Chinese students.Several factors can account for the above difference.For one thing, independence is highly honored in American society and students take great pride in self-reliance.For another, American students have a more flexible schedule so they can have more time to do part-time jobs.Another contributing factor is that both Chinese students and their parents take parents’ financial support for granted.The tendency for Chinese college students to rely on their parents for finance may be changed.The widespread adoption of credit-system will give Chinese students more time and flexibility to pursue part-time jobs and get more independence from their parents.What’s more, great changes may take place not only in the students’ ideas but also in their parents’, which, in turn, will lead Chinese students to regard it as a pride to be self-reliant.如何用英語描述圖表
