英语说明文的写作技巧说明文是阐述事物的特征、本质、性能、结构、用途或科学原理的一种文体。其说明的对象可以是具体的，如：自然环境，仪表设备等；也可以是抽象的，如概念定律等。说明文的写作相对于论说文来说，有一定的套路可循，因此不是十分复杂。说明科技方面的内容常用定义法、比较对比法、分类法、因果法等；说明自然环境方面的内容常用时间次序法、分类法等。当然，随着对象的不同，具体应该采用的方法也会有所不同。说明文的写作应该注意的事项有下面几点： 1.语言简明扼要，通俗易懂，避免夸张华丽的辞藻，要把真实的一面展现在读者面前。 2.说明时一定要把握一个中心主题。说明文中细枝末节较多，但不能喧宾夺主。 3.说明的次序非常重要。合理的次序会使文章条理清楚，脉络明晰。因此，练习时可以尝试不同的次序进行写作，找出最合理的一种。 4.由于说明文写实性较强，有时难免会让人感到没有生气。因此，可以适当使用一些比喻、拟人等修辞手段，来增加文章的色彩。下面是一篇说明一所医院布局的文章。文章虽短，但需要说明的内容却达11处之多。平均一句话就要描写一处，如果组织得不好，便会给人凌乱的感觉。为了避免这一点，文章把整个布局图分三部分来写：贯彻医院的是main road 第一部分以大门为参照物，介绍了靠大门且通过main road东西相对的急诊楼和门诊楼。第二部分以湖为参照物，中心线还是main road，介绍其他分诊楼、实验室、放射室等。第三部分写main road尽头的建筑物。这样，繁多的细节显得井井有条。因此，选择好主线及参照物是决定文章成功的关键。 Directions:For this part,you are allowed 30 minutes to write a composition about＂THE LAYOUT OF A HOSPITAL＂.Locate some important departments in the hospital based on the information given below.Your composition should be no less than 120 words.
