怎样写科普短文
科普文章实属一种说明文体裁。它要真实于科学，不能虚构。根据书面材料要求，一一说明 清楚即可。用英语写说明文，要注意如下几点：
一、特征要抓住
说明某事物，就必须从某物的特征入手。例如：颜色、大小、高矮、胖瘦、形状、形态、性质、性能、习性、原理、作用、用途、功能、危害、影响、结构、操作、程序、发生、发展的规律等。
二、层次要分明
说明某物，可从上至下，从前到后，由里到外，由主到次或先因后果。
三、解析要清楚
对某一事物的说明，要表达清清楚楚。例如写长城就得从长城的位置、历史、起因、构造、 修造过程以及现在状况等方面入手。
四、表现手法要多样化
说明某一事物，可以运用比喻手段，如拟人或拟物。如高中课本里把蚁窝比作“蚁城”(acuity of ant people)；把蚂蚁称作为“蚁民”(ant people)；把专管食物的蚂蚁称为“工蚁”(the workers)；把专管保育幼蚁的称为“保育蚁”(nurses)；将蚁城统治者称为“蚁后”(the queen)。
五、用词要力求准确
引用的数据要绝对可靠。文字要精练。如高中课本中的The Tallest Grass，称竹子为最高 的草。①突出“高”；②突出它是一种“草”。
