　　英语四六级写作备考离不开常用句型和模板，很多同学都喜欢将四六级写作留待考前进行冲刺，这在准备时间不足的情况下是最合适的选择，但“慢工出细活”，想要高分仍然需要平时的点滴积累，下面来学习一点英语四六级写作模板方法吧，备考从细微处着手。
　　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.

The building to the southwest of the lake is the Dispensary, which faces the Surgery Department lying on the other side of the road. Along the west wall, from south to north, stand three buildings: the Physician Department, the Eye, Ear, and Throat Department, and the Dental Department. The Laboratory is to the northwest of the round about, and beside the Laboratory, the X-ray Department is located on the same side of the road.
　　A winding road by the lake leads to the Ward. Near the end of the main road, the Administrative Building is situated on the east side. The hospital is nicely and conveniently laid out.
　　1. How to Lose Weight
　　思路提示：第一段先综述现象：大家都想保持身材要求减肥。第二段介绍多余的体重在身体中形成的原因。第三段提出相应的减肥方法。在最后一段，提出总结性的看法，指出减肥的要诀就是：减少摄入的卡路里，通过运动增加卡路里的消耗量。
　　参考范文
　　How to Lose Weight
　　A beautiful and healthy figure is everyone’s dream. However, not everyone can easily fulfill this dream. Overweight people often have to find precise ways to lose weight.
　　For normal healthy people, weight is gained by taking in more calories than the body needs. Therefore, if you want to lose weight, you either have to eat fewer calories or find ways to use up more calories you take in. Dieting is probably the most popular way of losing weight, because when on a diet, you are taking fewer calories.
　　However, the body needs many elements in order to stay healthy, and “fad” or starvation diets are bad because they are not nutritiously balanced. A better way of dieting is to keep track of everything you eat, either by your own careful choices or by buying, for a week at a time, the packaged meals sold by some diet companies. If you do not normally exercise, you should also begin sensible exercises for your age and lifestyle to help your body use up surplus calories.
　　In short, a combined effort of reducing the calories you eat and using up more calories than usual through exercises should help you shed off part of your body.
