写说明文,一定要对说明对象有比较深刻的认识,即抓住说明对
象的特征。什么是事物的特征呢?特征就是某事物区别于其它事物的象征和标志,即该事物所特有的个性。它往往表现在两个方面:一是外显性特征,如事物的颜色、质地、空间位置、形状、温度等;二是内隐性特征,如事物的成因、原理、变化过程、内部结构、习性、性能、风格等方面。
那么怎样才能把握住事物的特征呢?必须从以下几个方面着手:一要认真观察。通过细致、反复、深刻的观察,用眼、耳、口、鼻、体、肤等感觉器官,对要说明的事物进行看、听、尝、嗅、触等,必要时,还可以做实验,以准确、全面地把握事物的特征。二要深入思考。将说明对象和类似的事物进行多方面比较,对掌握的有关信息进行筛选,深入分析其异同,抓住了“异处”,就把握了该事物的特征,也就抓住了说明的重点。三要重视积累、扩大生活视野,阅读范围,不断丰富知识,积累写作材料,注意间接的获得,提高理性认识水平。

可是他穿过铁道,要爬上那边月台,就不容易了。
他用两手攀着上面,两脚再向上缩;他肥胖的身子向左微倾,显出努力的样子。
这时我看见他的背影,我的泪很快地流下来了。
我赶紧拭干了泪,怕他看见,也怕别人看见。
我再向他看时,他已抱了朱红的桔子望回走了。
过铁道时,他先将桔子散放在地上,自己慢慢爬下,再抱起桔子走,到这边时,我赶紧去搀他。
