高三学生高考前复习辅导工作计划（10篇）高三学生高考前复习辅导工作计划篇1高三数学学习可以分为三个阶段：1.一轮复习(至元旦前后)：夯实基础，构建知识体系，强化能力训练;2.二轮复习(从一轮结束至三模结束)：固化与应用，优化思维模式;3.考前冲刺(考前一个月)：巩固已知，调整状态。

一轮复习特点：时间长，任务重，此特点与《课程标准》中“培养学生实事求是的态度，锲而不舍的精神”吻合;学生易懈怠、易迷茫、易焦虑。

一轮复习数学资料：一轮复习讲义、教材(10本)、章节测试、__年——__年高考试题分类汇编、__套模拟试题、高考真题。

一轮复习着重从知识、方法、能力、技巧四方面入手，为实现二轮复习“数学思想统领学习”的目标做下坚实基础。

知识与方法可以跟随老师的讲解及时整理记忆，与原有知识结构实现对接，实现知识与方法的零死角;能力的提升需要自己细致扎实的练习与思考，基础能力：总结反思、语言表达、阅读理解，学科能力：空间想象、抽象概括、推理论证、运算求解、数据处理;技巧是从勤勉的实践中点滴积累起来的，是反复感知与应用后沉淀下的极其实用的小绝招，每个个体总结的技巧是不尽一致的。

一轮复习思路千百种，现仅从“如何搭配练习册及试卷的应用”的角度对一轮复习大致框架加以论述：1. 无论复习哪一学科，都要有一个系统的练习过程，认准一本复习资料加以练习不放松。

课堂上，按照拟好的“主线”进行复习，“函数、几何、概率统计、运算、算法、数学应用”六条主线将课标内容纵横交织，打破资料章节顺序，优化组合串讲课标所要求考点。

2. 新课标精神的直接体现就是教材，重读教材意义重大。

要读初学时未关注的细节，要关注数学概念、法则、结论的发展过程。

教材上练习题不必每道必做，根据实际情况，有选择地挑出一些必做题。

我将依照教材内容组织一张练习卷，尽可能检验出大家对教材的熟悉程度及理解的深度。

3. 必备的章节模拟训练是不可少的，一段时间的复习后来个小测验，及时对所学有一个检验，也时刻提醒我们要注意多回头看看。

新课标高考二轮专题复习基础训练试题Document number【SA80SAB-SAA9SYT-SAATC-SA6UT-SA18】高一语文基础训练（三）小说阅读：魔盒（英）大卫洛契佛特（1）在一抹缠绵而又朦胧的夕照的映衬下，我四周高耸着的伦敦城的房顶和烟囱，似乎就像监狱围墙上的雉堞。

从我三楼的窗户鸟瞰，景色并不令人怡然自得——庭院满目萧条，死气沉沉的秃树刺破了暮色。

远处，有口钟正在铮铮报时。

（2）这每一下钟声仿佛都在提醒我：我是初次远离家乡。

这一年，我刚从爱尔兰的克尔克兰来伦敦碰运气。

眼下，一阵乡愁流遍了我全身——这是一种被重负压得喘不过气来的伤心的感觉。

（3）这是我一生中最沮丧的时刻。

接着突然响起敲门声。

（4）来人是女房东贝格斯太太。

刚才她带我上楼看房时，我们只是匆匆见过一面。

她身材纤细，银丝满头；我开门时她举目望了望我，又冲没有灯光的房间扫了一眼。

（5）“就坐在这样一片漆黑中，是吗”我这才想起，我居然懒得开灯。

“瞧，还套着那件沉甸甸的外衣！”她带着母亲般的慈爱拉了拉我的衣袖，一边嗔怪着，“你就下楼来喝杯热茶吧。

噢，我看你是喜欢喝茶的。

”（6）贝格斯太太的客厅活像狄更斯笔下的某一场景……她一边准备茶具一边说，“你进屋时我注意到了你手提箱上的标签。

我这一辈子都在接待旅客。

我看你的心境不佳。

”（7）当我坐下和这位旅客的贴心人交谈时，我的忧郁感渐渐被她那不断地殷勤献上的热茶所驱散了。

（8）随后，我告诉贝格斯太太我必须告辞了。

然而她却坚持临走前给我看一样东西。

她在桌上放了一只模样破旧的纸板盒——有鞋盒一半那么大小，显然十分“年迈”了，还用磨损的麻绳捆着。

“这就是我最宝贵的财产了，”她一边向我解释，一边几乎是带有敬意地抚摸着盒子，“对我来说，它比皇冠上的钻石更为宝贵。

真的！”（9）我估计，这破盒里也许装有什么珍贵的纪念品。

是的，连我自己的手提箱里也藏有几件小玩意——它们是感情上的无价之宝。

（10）“这盒子是我亲爱的母亲赠给我的，”她告诉我，“那是在1912年的某个早上，那天我第一次离家。

“PM2.5”是指大气中直径小于或等于2.5微米的细小颗粒物，也称为可入肺颗粒物。

下列有关说法中，错误．．的是()A．雾属于胶体，能产生丁达尔现象B．持续大雾天气给农业生产、交通运输等带来很大的影响C．大雾的形成与汽车的尾气排放没有关系D．空气中悬浮的细小颗粒物严重危害人体健康2．下列有关说法中，正确的是()A．分馏、干馏都是物理变化B．127I和131I互为同素异形体C．硫酸铜、二氧化硫都是电解质D．盐酸、漂白粉都是混合物3．下列说法在一定条件下可以实现的是()①酸性氧化物与碱发生反应②弱酸与盐溶液反应可以生成强酸③没有水生成，也没有沉淀和气体生成的复分解反应④两种酸溶液充分反应后的溶液体系为中性⑤有单质参加的非氧化还原反应⑥两种氧化物反应的产物有气体A．①②③④⑤⑥B．②④⑤⑥C．①②③⑤D．③④⑤⑥4．在离子浓度都为0.1 mol/L的下列溶液中，加入(或通入)某物质后，发生反应先后顺序正确的是()A．在含Fe3＋、Cu2＋、H＋的溶液中加入锌粉：Cu2＋、Fe3＋、H＋B．在含I－、SO2－3、Br－的溶液中不断通入氯气：I－、Br－、SO2－3C．在含AlO－2、SO2－3、OH－的溶液中逐滴加入硫酸氢钠溶液：OH－、AlO－2、SO2－3D．在含Fe3＋、H＋、NH＋4的溶液中逐渐加入烧碱溶液：Fe3＋、NH＋4、H＋5．已知H2O2既具有氧化性，又具有还原性，下列有关H2O2的说法正确的是() A．将足量的H2O2加入H2SO4和KI的混合溶液中产生无色气体，溶液变成棕色，发生的反应可能为：H2O2＋2I－===I2＋O2↑＋2H＋B．将H2O2和HBrO溶液混合，产生无色气体，发生的反应可能为：4HBrO＋2H2O2===4HBr＋3O2↑＋2H2OC．常温下，往H2O2溶液中滴加少量FeSO4溶液，可发生如下两个反应：2Fe2＋＋H2O2＋2H＋===2Fe3＋＋2H2O，2Fe3＋＋H2O2===2Fe2＋＋O2↑＋2H＋，可认为Fe2＋能催化H2O2的分解D．在酸性条件下，高锰酸钾溶液与双氧水发生反应，其离子方程式为2MnO－4＋H2O2＋6H＋===2Mn2＋＋3O2↑＋4H2O6．在图D2－1点滴板上有四个溶液间反应的小实验，其对应反应的离子方程式书写正确的是()图D2－1A．a反应：Fe2＋＋2H＋＋H2O2===Fe3＋＋2H2OB．b反应：HCO－3＋OH－===CO2－3＋H2OC．c反应：H＋＋OH－===H2OD．d反应：Al3＋＋3NH3·H2O===Al(OH)3↓＋3NH＋47．常温下，下列各组离子在所给条件下一定能够大量共存的是()A．pH＝0的溶液中：Fe3＋、Mg2＋、Cl－、SO2－4B．水电离出的c(H＋)＝1×10－10的溶液中：K＋、HCO－3、Na＋、S2－C．使pH试纸显深蓝色的溶液中：Cu2＋、Fe3＋、NO－3、SO2－4D．能与金属铝反应放出氢气的溶液：Mg2＋、SO2－4、NO－3、Na＋二、非选择题(本题包括4小题，共58分)8．(16分)已知四种强电解质溶液，分别含有下列阴、阳离子中的各一种，并且互不重复：NH＋4、Ba2＋、Na＋、H＋、SO2－4、NO－3、OH－、CO2－3，将这四种溶液分别标记为A、B、C、D，进行如下实验：①在A或D中滴入C，均有沉淀生成；②D和B反应生成气体，该气体能被足量的A吸收；③A和D反应生成的气体能被B吸收。
