今天我们一起学习《习近平谈治国理政》第一卷第十八章《提高党的领导水平》。这一章节共有4篇文章,第一篇文章《发扬钉钉子精神,一张好的蓝图一干到底》,这篇文章是习近平在中共十八届二中全会第二次全体会议上讲话的一部分,其中习总书记指出领导干部要牢记‘空谈误国,实干兴邦’,要做出经得起实践、人民、历史检验的实绩”。具体要从以下三个方面着力:一是我们党员干部既要大胆创新、锐意进取,更要保持工作的稳定性和连续性。要通过扎扎实实的努力,锲而不舍把毛泽东思想、邓小平理论、“三个代表”重要思想、科学发展观,以及中央作出的各项重大战略部署一以贯之地贯彻到各项工作中。二是要以钉钉子精神,将一张好的蓝图一干到底。一张好的蓝图,只要是科学的、切合实际的、符合人民愿望的,全体党员干部就要一茬接着一茬干,既要稳妥接续前期工作,又要适时调整和完善工作计划,脚踏实地地把既定的科学目标、好的工作蓝图变为现实。三是各级党员领导干部要切实树立正确的政绩观。要多做打基础、利长远的事,要以“功成不必在我”的精神,求真务实,真抓实干,勇于担当,真正做到对历史和人民负责。
第二篇文章是《依靠学习走向未来》,这篇文章是习近平总书记在中央党校建校80周年庆祝大会暨2013年春季学期开学典礼上讲话的主要部分。习总书记指出,在党内相当一个范围、相当一个时期内,实际存在着党员干部“本领恐慌”的问题。这种本领恐慌,一方面来源于新时代知识更新速度的不断加快,一方面来源于世情、国情、党情不断发展变化所引起的新情况新问题,导致很多同志在工作中解决问题“新办法不会用、老办法不管用、硬办法不敢用、软办法不顶用”。增强本领,克服“本领恐慌”,学习是最直接有效也是唯一的方法。要从以下三个方面做起:
第一,我们要知道“学什么”。一是认真学习马克思主义理论,这是我们做好一切工作的看家本领,也是领导干部必须普遍掌握的工作制胜的看家本领。二是深入学习党的路线方针政策和国家法律法规,这是领导干部开展工作要做的基本准备,也是很重要的政治素养。三是结合自身工作需要学习专业知识,要坚持干什么学什么,缺什么补什么,努力掌握履行岗位职责所必备的各种知识,使自己真正成为行家里手。四是学习中华民族优秀传统文化,它不仅可以益智、修身,更能帮助我们树立正确的世界观、人生观、价值观,其中所体现的民族精神和气节,更是值得我们永远继承和发扬。
第二,我们要清楚“怎么学”。一是要培养学习兴趣。学习贵在持之以恒,重在学懂弄通,不能心浮气躁、浅尝辄止。要把学习作为一种追求、一种爱好、一种健康的生活方式,养成学习的浓厚兴趣。二是要把握正确的学习方向。要始终以马克思主义为学习的方向指引,明辨和抵御各种错误的思潮,准确从各类知识中取其精华、去其糟粕,从中获得积极向上的阳光正能量。三是要注重理论与实践的有机结合。既要抓住学习重点,也要注重多领域学习;既要向书本学习,也要向实践学习;既要向人民群众学习,向专家学者学习,也要向国外有益经验学习;要有理论知识的学习,也要有实践知识的学习。
第三,我们要明白“学完之后怎么做”。学习的目的在于运用、增强工作本领,提高解决实际问题的水平。我们要发扬理论联系实际的马克思主义学风,带着问题学,做到干中学、学中干,学以致用,用以促学。
第三篇文章是《治大国若烹小鲜》,这篇文章是习近平总书记在接受金砖国家媒体联合采访答问的一部分。其中,习总书记引用《韩非子·显学》中的一句话,“宰相必起于州部,猛将必发于卒伍”,充分印证了领导干部基层经历的重要性。有了丰富的基层经验,就能更好树立群众观,知道人民群众需要什么。领导干部不单要具备能力和才干,更不可或缺的是对社会对百姓高度的责任感。所以我们必须要俯下身子,深入群众中了解社情民情,夙夜在公,勤勉工作,对待祖国的建设工作如同一位追求完美的匠人,精雕细琢、精益求精,如此这般,泱泱中国才能更加繁华锦绣,欣欣向荣。
最后一篇文章是《着力培养选拔党和人民需要的好干部》。习总书记指出,我们要确保党在发展中国特色社会主义历史进程中始终成为坚强领导核心,要建设一支宏大的高素质干部队伍,最基本的便是选贤任能,要选出好的干部,才能干出好的成绩。习总书记进一步阐述了有关“好干部”的3个问题。
第一,怎样才算是“好干部”。时代赋予“好干部”的新内涵主要有“政治上靠得住、工作上有本事、作风上过得硬、人民群众信得过”等具体要求。第二,怎样成长为好干部。好干部的成长,离不开自身努力和组织培养。党员干部要通过终生努力来提高党性修养、思想觉悟和道德水平,要时刻自重自省自警自励,做到心不动微利之诱,目不眩于五色之惑,老老实实做人,踏踏实实干事,清清白白为官。第三,怎样把好干部用起来。用一贤人则群贤毕至,见贤思齐就蔚然成风。选什么人就是风向标,有什么样的干部作风,乃至就有什么样的党风。因此,党管干部这一原则必须坚持,各级党委和组织部门要做到选贤任能、用当其时,知人善任、人尽其才。
学习这四篇文章后,我们应该清楚地认识到,要全面从严治党,不断提高党的执政能力和领导水平,政治建设是首位。全体党员干部一定要有打铁还需自身硬的思想觉悟,增强“四个意识”,坚定“四个自信”,坚决做到“两个维护”,不断用习近平新时代中国特色社会主义思想武装头脑,始终坚持党的领导和各项方针政策,保持一张蓝图绘到底的决心和毅力;始终坚持从做群众中来,到群众中去,以关系群众切身利益的事为工作的头等大事狠抓落实,做一个全心全意为人民服务的人;始终坚持不断提升自己的文化修养和政治素质,以更好的精神状态,更饱满的工作热情,在实现共产主义的道路上奋勇前进。

6、就业:
Directions: For this part you are allowed 30 minutes to write a composition on the topic Jobs for Graduates. You should write at least 120 words and base your composition on the outline below:1、大学生难找工作,2、原因很多,3、解决的办法。
Job hunting has always been a headache for college students. Though many graduates are employed right after graduation, some are not. Most serious of all, some still have no idea where to go working even a long time after graduation.
The reasons for this phenomenon are various. On the one hand, a few years ago colleges and universities enrolled so many students in popular majors, such as economy, finance and so on that the number of graduates was greater than the need in the market. On the other hand, most graduates would rather stay in large cities without suitable job to do than go to the country.
I reckon this problem can be solved if both colleges and students take
measures. First, they should research the market and develop special skills to suit its need. Second, students’ attitude towards employment should be
changed. They should go to small cities and country. There they can also give full play to their professional knowledge. In a word, if we pay much attention, the situation can be improved.
7、考试:
Directions: For this part you are allowed 30 minutes to write a composition on the topic My Views on Examinations. You should write at least 120 words and base your composition on the outline below:1、大学都用考试来衡量学生的成绩,2、考生可能带来的副作用,3、我对考试的看法。
In most colleges and universities the examination is used as a chief means of deciding whether a student succeeds or fails in mastering a particular subject. Although it does the job quite efficiently, its side effects are also enormous.
To begin with, examinations lower the standards of teaching. Since teachers are often judged by examination results, they are reduced to training their students in exam techniques. No subjects can be taught successfully merely through being approached with intent to take examinations. In addition, the most undesirable effect is that examinations encourage bad study habits. As the examination score is the only criterion for his academic performance, a student is driven to memorize mechanically rather than to think creatively.
In fact, few of us admit that examinations can contribute anything really important to the students’ academic development. If that is the case, why cannot we make a change and devise something more efficient and reliable than examinations?
8、读后感:
Directions: For this part you are allowed 30 minutes to write a composition on the topic My Favorite Novel. You should write at least 120 words and base your composition on the outline below:1、我最喜爱的小说,2、该小说的内容,3、我为什么喜爱。
My favorite novel is Around the World in Eighty Days which is written by Jules Verne. The author was born in France and devoted himself to literature and wrote several scientific romances, which gained him the name——Father of Modern Science Fiction.
This is a book of science fiction which tells us an exciting story about an English gentleman, Mr. Phileas Fogg, who makes a bet with his clubmates and manages to travel around the world in eighty days. It gives us a vivid
description of the many difficulties and incidents which happen on his journey.
From this story, we can see the author’s deep love for the sea, travel and adventure, which played a vital role in his life. We are also astonished and convinced by his fertile imagination and scientific and geographical knowledge.
9、难忘的人:
Directions: For this part you are allowed 30 minutes to write a composition on the topic The most unforgettable Person I ever Know. You should write at least 120 words and base your composition on the outline below:1、我生活中最难忘的人是,2、为什么他(或她)令我难以忘怀,3、结论。
In my life I have met a great many people who are really worth recalling. But perhaps the most unforgettable person I ever know is my English teacher.
What frequently brings back memories of my school teacher is his special qualities. First and foremost, he gave us the greatest gift a teacher can offer—an awakening of a passion for learning. He not only led us to an
appreciation of the beauty and perfection of English language and literature, but also aroused our great interest in exploring something deeper in this field. Furthermore, I was attracted by his lively wit. I remember that we students always anticipated his class with great eagerness because his lecture were humorously delivered, never failing to provoke chuckles or loud laughs.
Although it is nearly two years since I attended his last class, he is the talk of our old classmates, and I know part of him has already stayed in my heart.
10、论说文框架:
Owing to the speedy economic development, the number of people who…has considerably increased/declined. It is universally acknowledged that … plays a crucial role in modern society.
Due attention has to be paid to the issue of…. With the reform and opening-
up in recent decades,people in mounting numbers have come to realize the significance of …. If we let this situation continue as it is, we do not know where humans will be in the forthcoming future.

物理和数学虽然都是理科,但做题的规范要求却相差很大。计算题孩子们丢分最多,原因大多是因为对物理计算题的步骤不熟悉,不是没写公式,就是漏了单位,下面给大家分享一些关于高考物理全国卷复习指导,希望对大家有所帮助。
高考物理全国卷复习指导1、加强审题能力的训练,引导学生读题、审题,让学生能准确地理解关键字眼,挖掘隐含条件,排除干扰因素,使学生在大脑中能重现题目的物理情景,并能快速地用语言、示意图和方程等形式“翻译”出来。
2、加强独立训练,包括独立审题、独立分析、独立决策、独立解题、独立检查、独立克服困难等,培养学生独立解决和处理问题的能力。
3、加强解题速度训练,每次训练限时90分钟,让学生在80分钟内能答题完毕;
要求学生把它当作实战来演练,让学生学会在考试中如何分配时间,不断积累考试经验。4、加强解题技巧的训练,让学生懂得选择题(理解、逻辑推理)、实验题(原理、方法的理解和应用,方法的迁移和灵活运用能力)和计算题(过程、模型、方法和能力)等不同类型题的题型分析、掌握解题方法和解题技巧。
掌握数学方法在解题技巧中的应用。5、研究评分标准,加强学生答题规范化的示范引导和强化训练,让学生掌握应试技巧,提高解题的规范性,增加得分点,考出更高分数。
6、落实训练,巩固成果,全面提升学生应变抢分能力
(1)由易到难,各个击破,对于物理成绩比较差的学生,可以考虑有选择地放弃一些“过难”的题目,让每个人的时间利用效率最大化;
(2)会做的题能够得全分,熟悉高考评分细则,领会其中精神,思路要严谨,说理要透彻,表述要准确,规范答题,清晰无误;
(3)不会做的题也要能得一部分分数,在实际考试中解答计算题时,有时候是题目较难,不能完整地解答出来,有时候是时间紧,没有时间做出最后的结果,此时学生应该按照现象发生的先后顺序,涉及几个规律,写几个方程,要尽量多写一点,当然,要规范答题。
高考物理解题注意的问题1、识别物理现象
识别物理现象的过程是在充分读懂、理解题目文字叙述的基础上,抓住己给的解题线索,形成具体问题情景的大致物理轮廓,并且对解题的方向作出初步判断的过程。识别物理现象包括理解题意和确定研究对象两个方面。理解题意是正确解答物理问题的关键。要迅速地理解题意,必须抓住题目中的关键字句,找出已知条件和所求物理量之间的关系,在必要时画出草图帮助理解题意。确定研究对象实际上是把题目所给的物理条件分析为研究对象和研究对象的影响因素的过程。
2、分析物理过程
物理过程是指物理模型在物理环境中的运动。变化过程。分析物理过程包括定性分析和定量分析两个方面。定性分析是从质的方面把握运动的性质、特点,找出运动的本质特点,排除非本质特征的干扰,建立起物理过程的模型。定量分析是指利用物理公式,找出物理量在各个于过程中的定量关系,特别是要找出物理过程中相同的物理量、不变化的物理量和临界状态的条件。
3、选择合适的方法
选择合适的方法是把物理问题转化为数学问题的关键之一。只有我们选择了合适解决问题的办法,我们才能顺利而简捷地解决问题。在这个环节,我们是用分析、综合还是反证、递推,是否要用隔离分析等方法。
4、运用数学知识解题
运用数学知识的过程是把物理问题转化为数学问题的关键环节。数学在这个过
程中的作用可以表现在以下三个方面。
①通过寻找数量关系,给物理模型加入定量的因素;
②用符号来表示物理量,从而使符号成为物理内容的载体,把复杂的事物代码化;
③根据物理规律列出问题中物理量之间的关系,实现物理过程的数学化。
当表示物理量之间的数学表达式列出以后,就应该运用数学知识准确地求出结果,并应注意提高解题效率。
5、讨论验证结果
讨论验证结果既是对原来的问题重新审视的过程,也是对自己的解题是否成功进行评价的环节。常用的讨论验证结果的方法有数量级估算法,特殊值假设检验法等。
高考物理审题的方法1、审题要慢,答题要快
所谓欲速则不达,考生看错一个字可能会遗憾终身,所以审题一定要慢,有了这个“慢”,才能形成完整的合理的解题策略,才有答题的“快”。
2、先易后难,敢于放弃
先易后难:一方面能够增强信心,使思维趋向成功,对发挥水平极为有利;另一方面如果先做难题,可能会浪费很多时间,所以关键时刻,要敢于放弃。比如,当一道选择题5分钟还没有得出正确答案,计算题最后一题的最后一问5分钟没任何思路,就放弃吧!
3、书写规范,步骤合理
试卷要给批卷人留下良好印象,必须书写规范,层次分明,要点清晰,重点突出,否则批卷人可能看不清,甚至找不到你的得分点。因此做解答题时应注意通式、分解式、详解式、答案四步法。
全国卷高考数学技巧方法为范文网的会员投稿推荐,但愿对你的学习工作带来帮助。
要想在高考数学考场上考出优异的成绩,不但需要扎实的基础知识,临考答题技巧也是非常重要的,下面给大家分享一些关于全国卷高考数学技巧方法,希望对大家有所帮助。
一.全国卷高考数学技巧方法1调整好状态,控制好自我。
(1)保持清醒。数学的考试时间在下午,建议同学们中午最好休息半个小时或一个小时,其间尽量放松自己,从心理上暗示自己:只有静心休息才能确保考试时清醒。
(2)按时到位。今年的答题卡不再单独发放,要求答在答题卷上,但发卷时间应在开考前5-10分钟内。建议同学们提前15-20分钟到达考场。
2通览试卷,树立自信。
刚拿到试卷,一般心情比较紧张,此时不易匆忙作答,应从头到尾、通览全卷,哪些是一定会做的题要心中有数,先易后难,稳定情绪。答题时,见到简单题,要细心,莫忘乎所以。面对偏难的题,要耐心,不能急。
3提高解选择题的速度、填空题的准确度。
数学选择题是知识灵活运用,解题要求是只要结果、不要过程。因此,逆代法、估算法、特例法、排除法、数形结合法……尽显威力。12个选择题,若能把握得好,容易的一分钟一题,难题也不超过五分钟。由于选择题的特殊性,由此提出解选择题要求“快、准、巧”,忌讳“小题大做”。填空题也是只要结果、不要过程,因此要力求“完整、严密”。
4审题要慢,做题要快,下手要准。
题目本身就是破-解这道题的信息源,所以审题一定要逐字逐句看清楚,只有细致地审题才能从题目本身获得尽可能多的信息。
找到解题方法后,书写要简明扼要,快速规范,不拖泥带水,牢记高考评分标准是按步给分,关键步骤不能丢,但允许合理省略非关键步骤。答题时,尽量使用数学语言、符号,这比文字叙述要节省而严谨。
5保质保量拿下中下等题目。
中下题目通常占全卷的80%以上,是试题的主要部分,是考生得分的主要来源。谁能保质保量地拿下这些题目,就已算是打了个胜仗,有了胜利在握的心理,对攻克高难题会更放得开。
6要牢记分段得分的原则,规范答题。
会做的题目要特别注意表达的准确、考虑的周密、书写的规范、语言的科学,防止被“分段扣点分”。
难题要学会:
(1)缺步解答:聪明的解题策略是,将它们分解为一系列的步骤,或者是一个个小问题,能解决多少就解决多少,能演算几步就写几步。特别是那些解题层次明显的题目,或者是已经程序化了的方法,每进行一步得分点的演算都可以得分,最后结论虽然未得出,但分数却已过半。
(2)跳步答题:解题过程卡在某一过渡环节上是常见的。这时,我们可以假定某些结论是正确的往后推,看能否得到结论,或从结论出发,看使结论成立需要什么条件。如果方向正确,就回过头来,集中力量攻克这一“卡壳处”。如果时间不允许,那么可以把前面的写下来,再写出“证实某步之后,继续有……”一直做到底,这就是跳步解答。也许,后来中间步骤又想出来,这时不要乱七八糟插上去,可补在后面。若题目有两问,第一问想不出来,可把第一问作“已知”,“先做第二问”,这也是跳步解答。今年仍是网上阅卷,望广大考生规范答题,减少隐形失分。
二.拿到150满分,数学高考要掌握的7个答题技巧与方法1.倒着解题。
大多数人读书,顺着读书。但是倒着读书,你尝试过吗?一般来说,成语、故事、寓言、俗语等都可以作为“逆向”阅读与训练。在阅读和写作时,运用逆向思考,可以颠覆一般的想法,可以激发新的观点,促使你想到少有想到的东西。顺着解题,在数学上是“由因索果”的思维方式。倒着解题,在数学上是“由果索因”的思维方式。如分析法、反证法、排除法等都是这种逆向思考方式。
在数学解题过程中,应用倒着解题的逆向思考,将会使你在困惑的解题过程中,发现新的思维曙光,顿悟“柳暗花明又一村”的心理感觉,体验学习成功后的乐趣与快感。倒着解题,是培养逆向思维的好方法。
在平时,加大逆向思维训练,才有可能在高考考试中,涌现一些新的独特的解题方法。否则,用传统的数学方法去解决一些高考难题,步骤冗长、繁琐、思维容易陷入困顿。但是,在高考紧张的时间面前,应用 “倒着解题”的逆向思考方式,有时你可能会灵光乍现、思维豁然开朗,一下子有醍醐灌顶的感觉,难题3~5分钟就可以解决。
2.大题小作。
在高考答卷过程中,不同题型要采取不同的方法进行解决。对于选择题与填空题,由于只填写结果,一步到位,应使用分析、估算、极值、排除、验证、转化等快捷方法,进行信息甄别,直接寻找结果,也可以利用特殊数、特殊值、特殊图形、特殊元素、特殊位置等特殊方法,尽量降低数学运算,简化数学过程,拨开迷雾见晴天,熟练、精准、快捷地解答,切忌“考场上小题大做”,避免在时间与思维上的浪费。
3.大题细作。
在高考考试中,由于数学按步骤给分,对于解答题的解决,应该把握好几个答题原则:注意解题步骤的严谨性与规范性;注意“书写的规范、表达的准确、语言的科学”,特别注意在得分点上要详写、而且还要写清楚。否则,会做的题目稍不注意,常会被阅卷老师“分段扣分”。如用均值不等式解题,不要漏掉等号成立的条件。概率解题,不能只列出几个式子或结论,就草率了事,也要用适当文字加以说明。4.发现“题眼”。
在高考考试中,发现题目题干中的“关键词”,即“题眼”,可使解题事半功倍。如2019年全国理科Ⅰ卷第5题,在题干“函数f(x)=在的图像大致为( )”中,可提炼出 “图像”这个重要信息关键词,把-x代入函数,得到f(x)是奇函数,再把特殊数值“π”代入,得到f(x)>0,便可得到结果,筛选出选项。
5.图解高考题。
图解法,就是数形结合法,即通过数与形的相互对应与转化来解决数学问题,主要包括“以形助数”与“以数解形”两个方面。一般来说,涉及函数、不等式、方程、确定参数的范围等问题时,应用数形结合法解决比较快捷、方便。
6.九九归一法。
老子在《道德经》中所言:一生二,二生三,三生万物,万物变幻,九九八十一变,又循环归一。但这种“周而复始”的循环往复,以至无穷,不是原地的轮回,而是由起点到终点,再由终点到起点,形成的一种螺旋式前进和发展的运动过程。
九九归一,就像日月交替、寒来暑往、四季轮回一样,周而复始,循环往复。九九归一,从本质上讲,就是数学的周期与周期现象。因此,数学的“周期现象”、“重复操作”、“同理上述”等数学内容,都可用“九九归一”的周期方法予以解决。如高考的“程序框图”题、“二次函数图形重复”题、“三角函数周期”题、“算法重复操作”题等等,一经发现都可用此法解决。
7.系统思考法。
彼得·安吉在《第五项修炼》中说:
“如果没有系统思考,各项学习修炼到了实践阶段,就失去了整合的诱因与方法。”
