如何判断英语阅读中常见的文章类型? 英语阅读的文章类型主要包括记叙文、描写文、说明文、议论文等。学会判断文章类型能帮助我们理解文章内容。 (1)记叙文要抓住事情的整体脉络。记叙文一般叙述某件事情的起因、经过和结果,有时还会包含一些背景及总结。 (2)描写文要抓住描写对象的特点与特征。描写文就是通过生动的语言对人物、景物或场面进行描写。 (3)说明文要抓住特点和关键词。高中英语阅读常见的说明文内容以科普和历史文化为主。无论是介绍人还是物,大多会从年代、文化背景、产生的影响等方面来说明。 (4)议论文要抓住文章论点和作者观点。高中英语的议论文常采用“总—分—总”结构。议论文三要素为论点、论据和论证。
