高一英语学习方法
1.英语是练习的，而不是学习的。这不仅是为了理解，更重要的是反复练习听、说、读、写。有时候你甚至不需要知道为什么，只要记得使用它。在使用过程中，他们会发现自己的语感有所提高。
2.新课程下英语学习的目的是培养学生的自主学习能力和语言综合运用能力(综合语言运用能力的形成是以学生的语言技能、语言知识、情感态度等为基础的)。在全面发展学习策略和文化意识的基础上。学习英语不仅是为了考试，也是为了将来的工作，甚至是终身服务。
学习中应注意的几个问题：(Dos和donts)
1、要一点地积累，不要急着去实现。
Romewasnotbuiltinaday!
渴望寻求成就可能会引起消化不良,或一无所有。高峰通常显示为对自己提出了更高的要求。往往会给自己很大的压力,然后渐渐对自己失去信心,失去兴趣。
Remember:10minutesadayisbetterthan10hoursaday!
尊重记忆规则，重复是关键。
AlwayskeepanEnglishbookathand!
少用时间：与其他学科交织在一起。早晨是学习英语的好时机。
2.建立信心，不要低估自己。
“即使是天才，他出生时的第一次哭泣也不是愉快的音乐。”听别人说好，焦虑，自卑情结，否定自己。其他人都受过训练。开始从来都不晚。要意识到建立信心的过程就是犯错误的过程。在你进步之前，你必须大胆地犯错误。
3.学识渊博，而不仅仅是课本
语言能力与语言材料的数量成正比。语言材料的输入量越大，语言能力的提高越快。背诵是加强语言材料输入的好方法，也是语言学习中不可缺少的一部分。这有助于记忆句型，而不是从上下文记忆单词。
注意flash生活的东西,如电影、电视、新闻、报纸、网络上出现的新的和有趣的东西。
4.主动进攻，不要等人教;要坚持，不要三天钓鱼，两天净干。
5.学会总结。学会理解规则，善于模仿，了解背景知识，区分语言应用环境。
6。积极参加各种与英语学习相关的课外活动。
高中英语与初中英语课程特点的变化
1.从浅层信息获取到深层信息加工的听、说活动。
2.词汇从普通生活词汇扩展到大量核心词汇和认知词汇
词汇学习是高中英语学习的重要组成部分。它渗透到英语学习的各个方面，包括听、读、格式塔、翻译和作文。此外，要提高对词汇的理解和应用，不仅要提高记忆水平，还要提高学生对词汇的理解和灵活使用。
