因此，去锻必须根据具体情况，选用合适的展开主题的写作手法，才能写出优秀的英语说明文。InChina，炼演coalminesarelargelyfoundinthenorth-westpartofthecountry.Shanxiisafamousprovinceforproducingcoal.IthasthemostcoalofChina.6.分类法（classification）分类法是将写作对象进行分类说明的一种写作手法。
但是无论是对客观具体事物的说明还是对主观抽象观念的阐述，讲稿英语说明文从结构上看大致可分为三个部分：讲稿第一部分一般是文章的第一段，提出文章的主题，也就是说，文章想要阐述、说明的主要内容。英语中常见定义句的模式是：晨风被定义对象is所属类别+限制性定语可以看出，晨风定义句中限制性定语越详细，定义就越精确，比如：Abatisasmallmouse-likeanimalthatfliesatnightandfeedson（以为食品）fruitandinsectsbutisnotabird.其实，在英英词典中，对英语单词的英文解释就是定义法的典型例子。
比如：去锻著名的英国哲学家弗朗西斯培根（FrancisBacon）在其脍炙人口的《谈读书》（OfStudies）一文中就用到了分类法：去锻Somebooksaretobetasted，otherstobeswallowed，andsomefewtobechewedanddigested，thatis，somebooksaretobereadonlyinparts，otherstoberead，butnotcuriously，andsomefewtobereadwholly，andwithdiligenceandattention.Somebooksalsomaybereadbydeputy，andextractsmadeofthembyothers。在英语中，炼演常见的用来展开文章主题的方法有下列几种：炼演1.罗列法（listing）在文章开始时提出需要说明的东西和观点，然后常用first，second，andfinally加以罗列说明。
