2024中考英语复习备考计划（4篇）

2024中考英语复习备考计划一、总体复习思路1、按单元复习。

通览初中教材，进行单元知识点扫描。

目的是对基础知识和基本技能进行系统的复习，把好“基础关”;任务是掌握各单元知识结构，全面地复习知识点，完成理解记忆;重点是重视课标要求与教材的基础作用，强化基础知识和基本技能的训练;面向全体，面向基础。

2、语法专项复习。

钻研考试标准和考试说明，进行语法、词法、句子、时态和话题专项复习。

统揽初中教材中的重点语法项目，使学生从整体上把握初中教材内容。

3、题型专练，模拟演练。

按照中考题型进行题型专练，了解学生对基础知识和基本技能的掌握情况，抓住中考题型变化，确定训练方式，进行查缺补漏。

二、实施步骤及时间安排第一轮：时间安排：____月____日-____月____日主要内容：初中教材课文中出现的单词、短语、常用句型;掌握4a、4b中罗列的重点句子，理解所学语法内容。

从初一开始，初一上下册花三个星期时间复习，从初二内容起每天复习一个topic。

同时在课上老师语法总结复习一下，再由老师针对学生的一些薄弱知识分单元编写一些练习讲义给学生加以练习，每个topic出一份小测，主要题型为：单词、词组翻译及句子的挖空填空等，以考察学生对基础知识的掌握情况。

针对____月底的口语考试，在这段时间内，我们还要穿插进行口语的复习辅导，利用下午第四节的时间让学生进行口语操练。

故大概在____月初可以完成第一轮复习第二轮：时间安排：____月____日-____月____日主要内容：结合中考新探索系统复习语法。

包括名词、代词、数词、介词和介词短语、连词、形容词、副词、冠词、动词、句子。

掌握动词六种时态的构成及基本用法和被动语态，即现在进行时、一般现在时、一般过去时、一般将来时、现在完成时、过去进行时。

句法包括掌握陈述句、疑问句、祈使句和感叹句的构成和基本用法，掌握简单句的五种基本句型、并列句、宾语从句、定语从句和状语从句。

第三轮：时间安排：____月____日-中考前（略）在前两轮复习的基础上，进行语法专项练习并针对中考题型进行专项强化训练，提高对各种题型的解题能力。

初中语文复习计划

初中语文复习计划(一)一、梳理课本，使本学期所学习的语文知识系统化。

二、分项复习1、基础知识积累及运用A、阅读本册所有的生字，记住它们的音、形、义。

B、古诗文默写：应该认真地背诵，正确规范地书写。

C、综合性学习活动：把本学期的综合性学习内容整理一下，梳理出老师平时强调的知识点。

D、文学常识：找出本册书的重要作者，掌握他们的“名、时、地、评、作”等内容。

E、名着阅读：在阅读了原着的基础上梳理出知识短文中的知识点，并牢记。

2、现代文阅读：主要是课内，选取课文的重点段，温习学习时的课文批注。

3、文言文阅读：注意文言词、句的解释及重点语段的理解并能概括出全文和每段的大意。

三、复习时应该注意的问题。

(一)、从思想上重视不少同学认为复习无非是平时已学过知识的重复，所以在复习阶段听课不够投入，最后导致不少知识都还是半生不熟。

而期末考试是对学生一个学期学习情况的检查与总结，考试时往往侧重于对一个学期知识的总结、综合。

仅靠平时的一些印象往往会顾此失彼，造成大面积的丢分。

从思想上重视，不麻痹大意，强调的不单纯是时间的投入，更是“头脑”的投入，惟独在复习课上真正用“脑”听课、思量、总结，才会使自己平时零散的所得到的知识系统的整理并进而成为一种能力。

(二)、复习讲究方法俗话说：工欲善其事，必先利其器。

意思是说无论做什么事，都要事先做好准备。

期末考试也是一样。

各种日常写作指导,教您怎样写要想取得好成绩，除了平时努力学习，打好基础，提高能力外，期末复习方法也很关键。

复习方法多种多样，应该根据自己的实际情况，选取科学、高效的复习方法。

这里向大家重点推荐的是最常规但很有效的复习方法，大家可以根据自己的实际情况选择使用。

1、明确考试范围，弄清本次期末检测的重点内容和重点题型。

复习时做到有的放矢。

2、根据考试的检查范围与要求对照检查自己的情况，并拟定适合自己的复习计划。

使复习有针对性。

3、提高自己的复习听课的效率，向效率要成绩。

薄弱之处加以强化，做到“查漏补缺”。

”该战役A．发生于公元2世纪初B．导致前秦统治土崩瓦解C．奠定了三国鼎立的基础D．实现了长江以北地区统一【答案】C【解析】据题干关键信息“公元208年”“曹操以舟师伐孙权，权将周瑜败于乌林、赤壁”并结合所学知识可知，材料反映的是赤壁之战。

208年孙刘联军在赤壁之战中以少胜多，大败曹操。

赤壁之战对当时整个局势有关键性的影响，为三国鼎立局面的形成奠定了基础。

C项正确；公元208年是3世纪初，排除A项；导致前秦统治土崩瓦解的是淝水之战，排除B项；赤壁之战并没有实现了长江以北地区统一，排除D项。

故选C项。

为三国鼎立局面形成奠定基础的战役是A．巨鹿之战B．官渡之战C．赤壁之战D．淝水之战【答案】C【解析】根据所学可知208年赤壁之战，孙吴联军打败曹操军队，为三国鼎立局面形成奠定基础，C项正确；巨鹿之战是秦末战役，排除A项；官渡之战为曹操统一北方奠定了基础，排除B项；淝水之战是东晋与前秦的交战，处于两晋时期，排除D项。

故选C项。

3．（2022年黑龙江绥化）官渡之战为三国鼎立的形成奠定了基础。

（）【答案】错误【解析】根据所学可知208年的赤壁之战，是孙刘联军对抗曹操，孙刘联军利用火攻打败曹操，奠定三国鼎立的基础，本题说法错误。

政治：2.4《生产与经济制度》分项练习试题（必修1）一、选择题一：生产决定消费1．(2011•广州模拟)近年来，随着互联网和计算机信息技术的发展，网购日渐成为人们购物的新时尚。

这说明() ①生产决定消费的方式②生产决定消费的质量和水平③居民的购买力不断提高④居民的消费结构不断优化A．①③B．①②C．②④D．③④解析：材料体现了随着信息技术的发展，出现了网购，这表明生产决定消费，③④不符合题意。

答案：B2．(2011•苏州模拟) 2011年我国实施积极的财政政策和稳健的货币政策，并以扩大内需特别是增加居民消费需求为重点，以稳步推进城镇化为依托，优化产业结构，使经济结构调整取得明显进展。

从经济生活角度看这是因为()①生产对消费起决定作用②消费对生产有重要的反作用③国民经济的健康发展离不开国家强有力的宏观调控④积极的财政政策比紧缩性财政政策更能促进经济发展A．①②③B．①③C．②③D．②③④解析：以扩大居民消费需求为重点，推进产业结构优化，这体现的是消费对生产的反作用，①不符合题意。

④观点片面，在经济发展滞缓时实施积极的财政政策才有利于促进经济发展。

中考英语复习计划(15篇)

中考英语复习计划(15篇)中考英语复习计划1近年来中考英语试题有了很大的改变，试题容量大，知识面广，对学生的能力要求很高，不仅加强了对英语基础知识的考查，更突出了对知识的灵活运用。

通过对大纲及考试说明的研究，我制定了“三轮复习法”作为最后三个月的总复习计划。

其特点是：先全面学习，后进行重点复习和考前适应性考试复习。

第一轮复习阶段时间从3月末4月末。

重点以知识点扫描为主，过教材，抓基础。

要充分调动学生的积极性，培养学生自我总结、自我归纳、自主学习的能力。

这个阶段应按教材顺序归纳语言点，讲透语言运用，对各单元的知识要点进行梳理，同时应注重基础词汇、词组、句型的过关。

第二轮复习阶段时间为4月末到5月末。

这个阶段主要用《初中学生能力自测》这本书，侧重专题练习。

好词汇、语法、写作等，让学生建立一个完整的网络。

此外，通过练习查漏补缺，用时解决存在的问题。

要求突出重点，牢固掌握。

在总揽教材，学生对基础知识掌握得比较扎实的基础上相应地提高要求，进行系统整理消化，抓住重点，加深理解，强化记忆。

第三轮复习阶段时间为5月末到6月中旬。

这个阶段是对学生的考前指导做适应性训练。

主要目的是适应中考要求，全面提升学生应对考试的能力提高应试技巧，知识考查和能力考查并重，从而使复习达到良好的良性循环。

总之，通过上述三轮复习，使学生从不同角度得到反复的复习和强化练习，由浅入深，既有点的知识，又有面的综合，使知识系统化，使能力得到提高和加强。

中考英语复习计划21、阶段训练（__年3月初-4月底）指导思想：按教材内容顺序，抓纲靠本，使学生从零散知识的学习自然过渡到知识的系统归纳上，使基础知识更加条理化。

在材料的整体处理及时间分配上，我们拟订在三月初开始着手总复习，抓住课本，从初一开始，初一上下册花一个星期时间复习，从初二内容起两天复习一个单元，重要单词、词组、句子，让学生对照着去复习。

同时在课上老师按时态等把语法总结复习一下，再由老师针对学生的一些薄弱知识分单元编写一些练习讲义给学生加以练习，每个单元出一份练习，主要题型为：词组翻译、选择题、首字母填词、词语释义、词形转换、翻译句子等。
