《英语课程标准》指出，"新一轮英语课程改革的重点就是要改变英语课程过分重视语法和词汇知识的讲解与传授、重视对学生实际语言运用能力培养的倾向，强调课程从学生的学习兴趣、生活经验和认知水平出发，倡导体验、实践、参与、合作与交流的学习方式和任务型的教学途径，发展学生的综合语言运用能力，使学习的过程成为学生形成积极的情感体验、主动思维、大胆实践，提高跨文化意识和形成自主学习能力 的过程。
《课程标准解析与教学指导》对高中阶段英语阅读技能目标提出如下要求： ·找出作者要传达的主要信息； ·按要求辨认语言结构、内容、事物发展顺序；·辨识内涵的主旨或观念； ·辨认、辨识、比较事实、证据和观点以及定义和假设性信息； ·对事实和证据进行评价,判断和预测； ·根据文中所提供的事实和证据得出结论； ·进行逻辑推断等：
