数学错题整理版汇总
数学（测试2 导数在研究函数中的应用） 题目：已知函数f（x）=xe-x（x∈R）。 （1）求函数f（x）的单调区间和极值；答：________ （2）已知函数y=g（x）的图像与函数y=f（x）的图像关于直线x=1对称。证明当x>1时，f（x）>g（x）；答：________ （3）如果x1≠x2，且f（x1）=f（x2），证明x1+x2>2。答：________ 解答：（1）f'（x）=（1-x）e-x。令f'（x）=0，解得x=1。 当x变化时，f'（x），f（x）的变化情况如下表： 所以f（x）在（-∞，1）内是增函数，在（1，+∞）内是减函数。 函数f（x）在x=1处取得极大值f（1），且f（1）=。 （2）证明：由题意可知g（x）=f（2-x），得g（x）=（2-x）e x-2。 令F（x）=f（x）-g（x），即F（x）=xe-x+（x-2）e x-2。 于是F'（x）=（x-1）（e2x-2-1）e-x。 当x>1时，2x-2>0，从而e2x-2-1>0。又e-x>0，所以F'（x）>0。从而函数F（x）在[1，+∞）上是增函数。又F（1）=e-1-e-1=0，所以x>1时，有F（x）>F（1）=0，即f（x）>g（x）。 （3）证明：①若（x1-1）（x2-1）=0，由（1）及f（x1）=f（x2），得x1=x2=1，与x1≠x2矛盾。 ②若（x1-1）（x2-1）>0，由（1）及f（x1）=f（x2），得x1=x2，与x1≠x2矛盾。 根据①②得（x1-1）（x2-1）<0。不妨设x1<1，x2>1。 由（2）可知，f（x2）>g（x2），g（x2）=f（2-x2），所以f（x2）>f（2-x2），从而f（x1）>f（2-x2）。因为x2>1，所以2-x2<1。又由（1）可知函数f（x）在区间（-∞，1）内是增函数，所以x1>2-x2，即x1+x2>2。 本题考查导数的运算、利用导数研究函数的单调性与极值等基础知识，考查运算能力及用函数思想分析解决问题的能力。
最新一般将来时易错题集锦
最新一般将来时易错题集锦 一、单项选择一般将来时 1． It is required that the students _____ mobile phones in their school, so seldom _____ them using one. A．should not use; you will see B．mustn’t use; will you see C．not use; you will see D．not use; will you see 【答案】D 【解析】 试题分析：考察情态动词。前一个空中，should表示劝告,义务,建议,命令,其同义词是ought to ，在疑问句中,通常用should代替ought to。后一个空前面有否定词seldom所以将will提前构成部分倒装。该句意思为：学生在他们学校被要求不要使用手机，所以你很少看见他们用手机。根据句意，故选D 考点：考察情态动词。 2．The computers made by our company sell best, but several years ago no one could have imagined the role in the markets that they ________. A．were playing B．were to play C．had played D．played 【答案】B 【解析】 试题分析：考查时态：我们公司生产的电脑卖的最好，但是几年以后没有人能想象它曾经将在市场中扮演什么样重要的角色。were to do是过去将来时，表示过去想象电脑将会起到的作用。选B。 考点：考查时态 3． Turn on CCTV news and we ________how happy our life is. But there is no denying that over the past decades, the cost of living ________ sharply. A．are seeing; had increased B．will see；has been increasing C．see; increased D．have seen; is increasing 【答案】B 【解析】 试题分析:考查动词时态。前句是固定句型“祈使句，and+句子（一般用将来时）”，而时间状语over the past decades是现在完成时态或现在完成进行时态的标志，所以B选项正确。句意：打开中央新闻联播我们就会看到我们的生活是多么的幸福。但是不能否认在过去的几十年里，生活费用一直在急剧上涨。 考点：考查动词时态。 4．If my brother doesn’t go to the evening party, .

(完整word版)小学数学错题集
小学“数学错题集” 恩格斯说：“无论从哪方面学习，都不如从自己所犯错误的后果中学习来得快。”孩子的学习就是一个不断犯错和不断纠错的过程。如果能把数学学习中所有的错题都集中在一起，引导学生反思，分析出错的原因，再经过系统、全面地分析、诊断，就能大面积地提高全班学生的正确率，把错误率降到最低。这就是建立“数学错题集”对 于教学的益处。 什么是数学错题集 数学错题集”是指学生在平时作业及形成性练习中出现的各 类错题的系统汇总。准备一本数学错题集，就是为自己建立一个 错误档案。具体来说，是让学生准备一本较厚的笔记本，把日常 数学练习和测试中做错的题目抄下来，或者裁剪、粘贴在错题本 上。通过对错题收集、整理、反思和合理利用，有效提高学生的 数学思维品质和能力。 为什么要建立错题集
①从实处入手，避免反复出错 练习和测验是检验学生数学知识掌握情况的重要方式，很多老师们都有这样的经验：许多上课讲过了、平时练过甚至考试考过的题目，仍然有学生做错，这常常让老师很恼火，让学生很遗憾。 分析原因时，我们一般会归咎为上课不专心，基础知识掌握不牢固，知识点学习存在漏洞。可反复讲练效果不佳，深层原因还有一点：学生对错题价值的认识不够。对平时练习中出现的错题，往往只是简单订正，没有深入分析原因。个别孩子在没有老师的监督下，甚至会偷懒，半问半抄完成订正，这为再次发生错误提供了更大可能性。 ②从细处收集，便于知识整理 学生做错题，老师都会要求及时订正，直接写在作业本上，为什么还要专门建立错题集呢？ 订正在作业本、练习册或者试卷上，比较分散。对于想要巩固的孩子，由于难以查找，不便整理，如果换了作业本，更是无从检查。等到时间长了，记忆就淡了。复习的时候没有了依据，只好全面撒网，导致复习没有针对性，效率大大降低。 在建立数学错题集的基础上进行复习，孩子把在各个单元中出现的错误都按本来面目集中到错题集上，学生有数、老师也有数，师生复习都有准确的依据。这样学生就可以减轻负担，提高效率。

A．didn’t show up B．won’t show up C．hadn’t showed up D．doesn’t show up 【答案】B 【解析】 试题分析：考查时态。根据语境及时间状语tomorrow afternoon可知用一般将来时。句意：——期望有多少人来参加你明天的宴会？——我送出了30份邀请，但三分之一将不会出现。故B正确。 考点：考查时态 2．If their marketing plans succeed, they ________ their sales by 20 percent. A．will increase B．have been increasing C．have increased D．would be increasing 【答案】A 【解析】 句意：要是他们的市场计划成功了，他们将增加20%的销售额。从句是一般现在时表将来，主句常用一般将来时或情态动词can/may＋动词原形。 3．AC Milan has confirmed that the England star David Beckham ______the team soon. A．has rejoined B．was going to rejoin C．rejoined D．is to rejoin 【答案】D 【解析】 试题分析：考查时态。本句考查的是将来时的一种表达法be to do sth将要做某事；句意：AC米兰俱乐部确认英国球星贝克汉姆将很快就重新加盟该队。本句的关键词是soon该词经常与将来时连用。故D正确。 考点：考查将来时的表达法 点评：在英语中将来时有多种表达法。Be to do sth表示计划的事情；或者表示注定要做某事；也可以表示命令做某事，相当于have to, must，should; will表示一般的将来，或者临时决定做某事；be going to do sth表示按照计划安排要做某事；或者根据某种迹象要做某事；be about to do sth即将做某事，不与表示将来时的时间状语连用。现在进行时表示一般将来时，表示按照计划安排要发生的事情，且动词要是一些表示位置变化的动词。 4．--- I’d like a mountain bike which ____ well? --- Will this one _____?
