  图表作文,我们在前面的课文中已经就图表作文的写作进行了详细的讲解。这里,我们再一次简要的说明一下图表作文的写作注意事项,作为图表作文讲解的一个小结。

  图表作文要求考生首先看懂图表意在表达的内容,然后准确地、条理清晰地进行分析、描述和概括。最后得出的结论。通常在写作时要特别注意以下三点:

  1.

  图表作文中有时给出很多的数据和事实,但考生不能在作文中像记流水帐一样将这些信息和数据一一罗列,而要根据图表要表达的核心内容,抓住关键的数据和事实作文章。如:曲线的突然变化,百分数的骤升骤降,柱状图中的表示数量或百分比的柱线的突然升高和降低,以及最高和最低的柱线。

  2.

  要细心观察图表。凡是图表中出现的内容都可能是有用的,写作时一定要尽量避免遗漏题目中给出的重要信息和数据。审题时必须先弄清楚图表的一些细节问题,如:横坐标、纵坐标各自代表什么,每个格的单位是多少,每种符号的意义是什么等等。

  3.

  当题目要求通过图表中的内容、变化趋势等分析原因、发表议论时,要注意发表议论必须紧扣主题,不可脱离主题泛泛而谈,或是越扯越远。自始自终都围绕着主题写作,才能使作文符合题目要求,写出成功的作文。

  写作提纲

  首段:交代该图表表达的内容,即美国能源的基本构成,并总体概述电能是如何获取的。

  主体段落:详细描写图表中反映的趋势,分别说明每种能源在电能生产中所占的比重。

  结尾段:得出结论:将来的能源供给必将出现危机,所以我们要积极寻找并开发新能源,如核能。

  The U.S. Energy Sourcesa

  This bar chart demonstrates the composition of US energy sources. Every day much electricity was consumed throughout the United States. But there is an amazing thing about electricity, that is, it doesn’t exist in nature in a form that we can use or find directly. How do we get the stuff that comes into our houses and offices, shopping malls and factories? In fact, it is obtained by converting other forms of energy.

  As we all know, electricity can be generated by means of hydro. However, it supplies only 10.5 percent of American capacity for generating electricity. Most of it is provided by steam that comes from boiling water. Steam factories for generating electricity cost a great deal of gas, oil or coal. The greatest US energy source comes from coal, accounting for 46.5 percent of the total production of electricity. The percentage of coal is four times greater than that of hydro. 16.9 percent and 13.7 percent of the country’s power is obtained by burning oil and gas respectively, which is an indispensable part in the production of electricity. obviously, due to the ever-increasing use of energy, there must be an energy crisis in the future. So it is necessary to get energy from other sources. Nuclear fuels, for instance, are used to generate electricity, and nuclear power makes up 12.4 percent of the total production of electricity.
