英语四级作文说明文模板(大学英语四级作文说明文)

说明文是用言简意赅的语言来介绍客观事物，讲清事理，并给人增加知识的一种文体。说明文解说事物的特点、发展变化规律，分析前因后果，目的在于使读者“明白事理”，获得必要的信息，对事物有个较完整明晰的了解和认识。说明文不同于记叙文和议论文，它重在给人介绍，让人明白，因而，轻“情义”重事实。说明文与议论文关系密切，有人将其统称为议论文。但在写作的目的和方法上两者仍有区别。说明文主要是通过事实客观地解释或说明事物本身；而议论文则以事实、数据等为证据，表明主观见解，使读者信服或赞同某一观点。

历年四级考试中的“How I Overcome Difficulties in Learning English”、“My Ideal Job”以及图表作文的第一段都属于说明文的范畴，如，2002年6月的根据坐标图写题为“Students Use of Computers”的作文。

说明文必须按一定的顺序进行说明：时间顺序、空间顺序、逻辑顺序或认识顺序，选择具体的特点和细节来说明。

所以，说明文的思路要围绕说明顺序、事物的特点和细节展开。例如：

范文点评

A Famous Clock

When you visit London, one of the first things you will see is Big Ben, the famous clock which can be heard all over the world on the B.B.C. If the Houses of Parliament had not been burned down in 1834, the great clock would never have been erected. Big Ben takes its name from Sir Benjamin Hall who was responsible for the making of the clock when the new Houses of Parliament were being built. It is not only of immense size, but is extremely accurate as well. Officials from Greenwich Observatory have the clock checked twice a day. On the B.B.C. you can hear the clock when it is actually striking because microphones are connected to the clock tower. Big Ben has rarely gone wrong. Once, however, it failed to give the correct time. A painter who had been working on the tower hung a pot of paint on one of the hands and slowed it down!

【点评】这是《新概念英语》中的一篇经典说明文，介绍了世界著名的“大本钟”。文章开篇指明该钟位于英国伦敦，且全世界的人们通过BBC就能够听到钟声。接下来讲述了“大本钟”的由来，特点——不仅外型巨大，而且走时准确，在结尾处讲了“大本钟”的一个幽默的小插曲——油漆工把油漆桶挂在指针上，把钟弄慢了。细读这篇文章，我们不难发现，区区159个单词就把“大本钟”的光辉形象牢牢地刻在读者的脑海里，为什么？本文基于事实，分析了主题的来龙去脉，语言简洁又不失生动贴切，作者态度客观又充满幽默，使读者既“明白了事理”，又对事物有较完整明晰的了解认识，此乃说明文之真谛也。

以“Goals”为题打开一篇说明文的思路。

参考思路

1）目标的分类：（可根据时间顺序，空间顺序、逻辑顺序或认识顺序，任选一个进行分类和排列）

2）各个类别的特点和细节：

3）组织成文：

范文点评

Goals

Everyone has goals. Many people do not reach their goals for lack of planning. These three sets of goals should be developed: lifetime, intermediate and short term.

Lifetime goals should be written out. These goals should be clear and reasonable. For instance, the goal to win a research prize is clear and measurable. Other lifetime goals might include publishing a certain number of influential books or articles, earning a departmental chairmanship at a major university, successfully competing for a grant from the National Science Foundation or securing a consultantship with a big corporation.

Intermediate goals relate to outcomes during the next few years. For the beginning doctoral student, intermediate goals may include completion of course work and preparation of a doctoral research proposal. Like lifetime goals, these are measurable and clearly stated.

Short-term goals involve outcomes expected during the next 12 months. These goals are more performance oriented, and they help with achievement of intermediate goals. Examples of short-term goals are earning an A in a course, learning how to program a computer or performing an experiment.

说明文的说明方法

对这些方法我们要了解并且掌握：

1. 定义法（definition）

定义法是用下定义的方式去揭示事物本质特征或概念内涵。它能使读者迅速抓住本质属性和基本特点。此法的句型：

① … is a/the … of … which/that …② … relate to/involve/refer to …

【例】

（1）Language is a system of arbitrary vocal symbols which is used for human communication. 语言是人类用来交际的任意性的语音符号体系。

（2）Intermediate goals relate to outcomes during the next few years.

（3）Short-term goals involve outcomes expected during the next 12 months.

2. 举例法（illustration）

举例法就是举出实际事例来说明事物的方法，是最常见，往往也是最有效的阐释模式。

专家提醒

举例时应挑选具体、典型且有能力表达清楚的例子，并注意按照一定的顺序编排。

请看上述范文第二段：“For instance”引出“lifetime goals”的实例，如，赢得研究奖金、出版有影响书或文章、获得大学的系主任职位、获得国家自然科学基金及大公司稳定的顾问职位。

3. 分类法（classification）

分类法就是把说明的对象，按一定的标准划分成不同类别分别加以说明的方法。如：上述范文介绍人生的三种目标，并按照时间的长短对终生目标、长期目标和短期目标做了分类说明。

4. 比较法（comparison）

比较法是用一个事物和与其有联系的其他事物加以对比的说明方法。目的是为了帮助读者准确地区分事物，通过对比达到对该事物的深刻认识。

如：上述范文对三种人生目标在时间上和实际操作上进行了比较，并阐明了彼此的联系。

（1）Lifetime goals should be written out.

（2）Like lifetime goals, these are measurable and clearly stated.

（3）These goals are more performance oriented, and they help with achievement of intermediate goals.

5. 数字法（statistics）

数字法是运用数据来表明事物的本质和特点，准确合理的数据使文章精确可信。

【例】

（1）Nearly half of all Americans over age 20 wear a bridge or denture，and more than 20 percent have complete upper and lower denture. By age 50, one out of every two persons has gum disease.

（2）And it seems sensible to wait. One quarter of all marriages between people under twenty-one end in divorce. In Britain in 1972, there were 124,248 divorces.

   听力的训练是一项系统工程。只靠多听，采取量中求质的办法，是很难大幅度地提高学生的听力的。要提高学生听力，应从以下几方面入手。1、读准语音正确的语音是听音辨音的基础，只有把英语音学准读准，才能进行听音辨音。因此，我要求学生每天早晨坚持半小时的听录音跟读练习，跟读过程中，只求读准语音。随堂设计5分钟的辨音练习，形式可多样化。比如：一生朗读，其余听辨有无错
