最新中考英语阅读理解专题(含答案)经典 一、初三英语阅读理解（含答案详细解析） 1．根据短文内容理解选择正确答案。 C What is your favorite color? Ask famous persons like Cate Blanchett, Scarlett Johnson, and Bono （singer for the band U2）, and maybe they will say “green.” That’s not because these artists like the color green best. Instead, they are interested in green fashion. Green fashion is about making （and wearing） clothes that are good for humans, animals, and the Earth. In the past, green fashion made people think of ugly clothes. But today, green fashion is different. It is about looking good and caring about the Earth and other people. You can have interesting clothes and be green. Around the world, green fashion is becoming popular. For example, the U.K. company People Tree sells me n’s and women’s clothing and accessories（配搭物）. They are made from natural fabrics（织物）like cotton and wool. Workers who make the clothes are from countries like Kenya（肯尼亚）, and Bangladesh（孟加拉国）. People Tree pays the men and women good money for the clothes they make. Singer Bono and his wife also started a clothing company called EDUN. When the clothes are sold, EDUN uses most of the money to help people around the world. （1）From this passage, we know that “green fashion” means________. A. putting green color on your face B. making clothes from green trees C. wearing the color green all the time D. wearing clothes that are good for the Earth （2）Today, green fashion is ___________. A. the same as it was in the past B. making people work harder C. more popular and interesting D. mostly popular with famous persons （3）Which sentence about green clothing companies is true? A.

2018年中考数学第二轮专题复习 专题一选择题解题方法 一、中考专题诠释 选择题是各地中考必考题型之一，2017年各地命题设置上，选择题的数目稳定在8～14题，这说明选择题有它不可替代的重要性. 选择题具有题目小巧，答案简明；适应性强，解法灵活；概念性强、知识覆盖面宽等特征，它有利于考核学生的基础知识，有利于强化分析判断能力和解决实际问题的能力的培养. 二、解题策略与解法精讲 选择题解题的基本原则是：充分利用选择题的特点，小题小做，小题巧做，切忌小题大做. 解选择题的基本思想是既要看到各类常规题的解题思想，但更应看到选择题的特殊性，数学选择题的四个选择支中有且仅有一个是正确的，又不要求写出解题过程. 因而，在解答时应该突出一个“选”字，尽量减少书写解题过程，要充分利用题干和选择支两方面提供的信息，依据题目的具体特点，灵活、巧妙、快速地选择解法，以便快速智取，这是解选择题的基本策略. 具体求解时，一是从题干出发考虑，探求结果；二是题干和选择支联合考虑或从选择支出发探求是否满足题干条件. 事实上，后者在解答选择题时更常用、更有效.
三、中考典例剖析 考点一：直接法 从题设条件出发，通过正确的运算、推理或判断，直接得出结论再与选择支对照，从而作出选择的一种方法。运用此种方法解题需要扎实的数学基础. 例1 根据表中一次函数的自变量x与函数y的对应值，可得p的值为（） A．1 B．-1 C．3 D．-3 对应训练 1．若y=(a+1)x a2-2是反比例函数，则a的取值为（） A．1 B．-l C．±l D．任意实数 考点二：筛选法（也叫排除法、淘汰法） 分运用选择题中单选题的特征，即有且只有一个正确选择支这一信息，从选择支入手，根据题设条件与各选择支的关系，通过分析、推理、计算、判断，对选择支进行筛选，将其中与题设相矛盾的干扰支逐一排除，从而获得正确结论的方法。使用筛选法的前提是“答案唯一”，即四个选项中有且只有一个答案正确.
2019-2020 年中考英语专题复习连词 连词是连接词、短语、从句语句子的词，它是虚词，所以不能单独担任句子成分。 知识梳理：提纲挈领，抓住重点和难点！ 连词的分类： 连词主要分为两大类：并列连词和从属连词。 1并列连词：用来连接并列关系的词、词组或分句。它包括：and, or, but, for , both…and, either …or, neither …nor, not only …but also 。 2、从属连词：用来引导从句，它包括：that ，when，till ，until after ，before ，since ，because, if , whether 。 though , although , so…that , so that , as soon as , as…as 等。 连词用法示例与解析: a i ” “ and ” 1.

九．几何应用题几何应用问题是近几年来中考的一大考点，它是把几何知识与实际问题相结合的一类题型，一般有这样几类：（一）三角形在实际问题中的应用；（二）几何设计问题；（三）折线运动问题；（四）几何综合应用问题。解决这类问题时，应结合实际问题的背景，抽象出几何模型，利用几何知识加以解决，然后再回到实际问题，进行检验、解释、反思，解题时应特别注意数形结合、分类讨论等数学思想。 一、三角形在实际问题中的应用例1．某校把一块形状为直角三角形的废地开辟为生物园，如图所示，∠ACB=90o，AC=80米，BC=60米。（1）若入口E在边AB上，且A，B等距离，求从入口E到出口C的最短路线的长；（2）若线段CD是一条水渠，且D点在边AB上，已知水渠的造价为10元/米，则D点在距A点多远处时，此水渠的造价最低？最低造价是多少？ C分析：本题是一道直角三角形的应用问题，解决此题首先要弄清等距离，最短路线，最低造价几个概念。1．E点在AB上且与AB等距离，说明E点是AB的中点，E点到C点的最短路线即为线段CE。B2．水渠DC越短造价越低，当DC垂直于AB时最短，此时造价最低。AED 本题考察了中点，点与点的距离，点与直线的距离，以及解直角三角形的知识。解：（1）由题意知，从入口E到出口C的最短路线就是Rt△ABC斜边上的中线CE。2222 在Rt△ABC中，AB=。（米） ∴CE=AB=×100=50（米）。22即从入口E到出AC BC 80 60 10011 口C的最短路线的长为50米。（3）当CD是Rt△ABC斜边上的高时，CD最短，从而水渠的造价最低。AC BC60 80 ∵CD?AB=AC?BC，
2019年中考数学二轮复习专题 各位读友大家好，此文档由网络收集而来，欢迎您下载，谢谢 教育网小编为大家整理关于中考数学二轮复习专题-因式分解，希望考生在各科复习中，做好安排，冲刺中考。 中考数学二轮复习专题-因式分解 因式分解：把一个多项式化为几个整式的积的形式，叫做把这个多项式因式分解，也叫做把这个多项式分解因式. 公因式：一个多项式每一项都含有的相同的因式叫做这个多项式的公因式. 确定公因式的方法：公因数的系数应取各项系数的最大公约数;字母取各项的相同字母，而且各字母的指数取次数最低的. 提公因式法：一般地，如果多项式的各项有公因式可以把这个公因式提到括号外面，将多项式写成因式乘积的形
式，这种分解因式的方法叫做提公因式法. 提出多项式的公因式以后，另一个因式的确定方法是：用原来的多项式除以公因式所得的商就是另一个因式. 如果多项式的第一项的系数是负的，一般要提出“-”号，使括号内的第一项的系数是正的，在提出“-”号时，多项式的各项都要变号. 因式分解和整式乘法的关系：因式分解和整式乘法是整式恒等变形的正、逆过程，整式乘法的结果是整式，因式分解的结果是乘积式. 运用公式法：如果把乘法公式反过来，就可以用来把某些多项式分解因式，这种分解因式的方法叫做运用公式法. 平方差公式：两数平方差，等于这两数的和乘以这两数的差，字母表达式：a2-b2= 具备什么特征的两项式能用平方差公式分解因式 ①系数能平方，
②字母指数要成双， ③两项符号相反. 用平方差公式分解因式的关键：把每一项写成平方的形式，并能正确地判断出a，b分别等于什么. 完全平方公式：两个数的平方和，加上这两个数的积的2倍，等于这两个数的和的平方.字母表达式：a2±2ab+b2=2 完全平方公式的特点： ①它是一个三项式. ②其中有两项是某两数的平方和. ③第三项是这两数积的正二倍或负二倍. ④具备以上三方面的特点以后，就等于这两数和的平方. 立方和与立方差公式：两个数的立方和等于这两个数的和乘以它们的平方和与它们积的差. 利用立方和与立方差分解因式的关键：能把这两项写成某两数立方的形式. 具备什么条件的多项式可以用分组

2019年中考英语阅读理解专题复习 (名师详细剖析解题技巧+实战训练，建议下载保存) (绝对精品文档，价值很高，值得下载打印) 一、解题技巧 英语阅读理解是综合语言运用能力的一个重要方面，阅读理解题是占篇幅最长的、最耗时间的、生词最多的、单题分值最高的题型，当然，阅读理解也成为了学生们头疼的题型， 下面就是初中英语阅读理解难点分析及高分秘诀，希望能助力同学们取得更好的成绩！ 初中英语阅读理解难点分析 1.单词不认识 很多同学都有这种感觉，平时课本上的单词自己都掌握了，为什么遇到阅读还是有很多看不懂呢?这类问题被归结为单词量不够。要解决这个问题，就是要多背单词，除此之外还 要摸索规律。 第一、人名、地名没必要较真。 英语中有大量的词总是大写第一个字母的，而他们也大多属于专有名词，表示人名，地名，事件。如Adela、Manchester、NATO。遇到这类词完全可以视若罔闻。 2.前缀、后缀有规律 英语中有些词通过前面或者后面加一些字母，就会变成另一个词。如，regular-- irregular，kind--kindness，前者通过加-ir变成起否定形式，后者通过在后面加-ness，变成了名词。归纳起来，一般说前缀变词义(如肯否定)，后缀变词性。只要记住这个原则，平时在学习时 有意识地去检验，积累各种加前后缀的形式，就不至于稍加变化就不认识了。
3.有的词是需要摸索的。 在阅读题中，有的词是在文章中有提示的，因为英语写作有个潜在的规则，词语若非不得已，不要重复。秉承这个原则，我们可以在文章的结构平行处找线索。或是反义词，或是 近义词，根据文章的具体情况，同学们不难做出一个比较有针对性的选择。 4.考纲单词必须熟记。 大纲要求的单词、平时做题总是遇到的单词，生活中会经常遇到的单词，这些词是同学们发挥才智，施展所有做题技巧的基础。没有特别好的方法，就是有恒心一直背：把单词表上的词分类，单独把不会的列出来，分批背，平时总是遇到又不认识的，用一本笔记本把他们都记下来，天天反复天天背。 文章看不懂 “单词我都认识，文章说什么我就是看不懂。”也许有的同学会这样说。问题可能出在这里： 第一、单词不是真的都认识。 英语中几乎每一个单词都不是只有一个释义，同学们所说的认识，也许只是这些单词的一个意思，有可能在文段中考查的是这个单词另外一个意思。这类情况要解决它，就把它当个生词来处理就行了。唯一不同的是，同学们对这类词的处理要注重在语境中理解，这样才能更好地区分不同词义。 第二、语法句式不熟。 这个原因更普遍一些。阅读中的句子有的是很长的，有的是很怪异的。长的可能是加了从句(主语从句、宾语从句、定语从句、状语从句)，怪的则有可能是倒装、插入语，这些语法点。解决这个问题就要解决语法弱项，认真学好每个语法现象，多去用学过的语法去分

中考数学第二轮专题复习 专题一选择题解题方法 一、中考专题诠释 选择题是各地中考必考题型之一，2013年各地命题设置上，选择题数目稳定在8～14题，这说明选择题有它不可替代重要性. 选择题具有题目小巧，答案简明；适应性强，解法灵活；概念性强、知识覆盖面宽等特征，它有利于考核学生的基础知识，有利于强化分析判断能力和解决实际问题的能力的培养. 二、解题策略与解法精讲 选择题解题的基本原则是：充分利用选择题的特点，小题小做，小题巧做，切忌小题大做. 解选择题的基本思想是既要看到各类常规题的解题思想，但更应看到选择题特殊性，数学选择题的四个选择支中有且仅有一个是正确的，又不要求写出解题过程. 因而，在解答时应该突出一个“选”字，尽量减少书写解题过程，要充分利用题干和选择支两方面提供的信息，依据题目的具体特点，灵活、巧妙、快速地选择解法，以便快速智取，这是解选择题的基本策略. 具体求解时，一是从题干出发考虑，探求结果；二是题干和选择支联合考虑或从选择支出发探求是否满足题干条件. 事实上，后者在解答选择题时更常用、更有效. 三、中考典例剖析 考点一：直接法 从题设条件出发，通过正确的运算、推理或判断，直接得出结论再与选择支对照，从而作出选择的一种方法。运用此种方法解题需要扎实的数学基础. A．1 B．-1 C．3 D．-3 思路分析：设一次函数的解析式为y=kx+b（k≠0），再把x=-2，y=3；x=1时，y=0代入即可得出kb 的值，故可得出一次函数的解析式，再把x=0代入即可求出p的值． 解：一次函数的解析式为y=kx+b（k≠0）， ∵x=-2时y=3；x=1时y=0， ∴ 23 k b k b -+= ? ? += ? ， 解得 1 1 k b =- ? ? = ? ， ∴一次函数的解析式为y=-x+1， ∴当x=0时，y=1，即p=1． 故选A． 点评：本题考查的是一次函数图象上点的坐标特点，即一次函数图象上各点的坐标一定适合此函数的解析式． 对应训练 1．（2013?安顺）若y=(a+1)x a2-2是反比例函数，则a的取值为（） A．1 B．-l C．±l D．任意实数 1．A
中考英语阅读理解专题复习（word）1 一、初三英语阅读理解（含答案详细解析） 1．阅读理解 Science fiction is a popular kind of writing, and many people think of Jules Verne（凡尔纳） as the father of science fiction. He was born in France in 1828. His father wanted him to become a lawyer, but from his early 20s Verne decided to become a writer. At first he wrote plays for the theater. Then, in 1863, he wrote a story called Five Weeks in a Balloon. The success of this book encouraged him to write more stories such as A Journey to the Center of the Earth（1864） and From the Earth to the Moon（1865）. In the 19th century, many people were interested in science and inventions. Jules Verne wrote about scientific subjects in his stories and, as a result, they were very popular. Verne's writing included many predictions（预言）for the 20th century and many of them came true. He described space flight, movies, and air conditioning, a long time before they appeared. These books were very successful and they made Verne rich. Jules Verne's books have been the subjects for many movies. 20, 000 Leagues under the Sea was a successful movie for Walt Disney. It was the first time that Disney movie had used real actors instead of cartoon drawings. Around the World in Eighty Days is another famous movie based on one of Verne's books.

Because he wrote many plays for the theater at that time. C. Because his books were the subjects for many movies. D. Because many people were interested in science and inventions. （4）Which of the following has the main character called Phileas Fogg? A. Five Weeks in a Balloon. B. Around the World in Eighty Days. C. A Journey to the Center of the Earth. D. From the Earth to the Moon. （5）According to the passage, which of the following is TRUE? A. The space flight Verne described was different from others. B. The main characters in Verne's books are always on time. C. Jules Verne only wrote in the 19th century. D. Many of the predictions in Verne's stories came true.
中考数学二轮专题复习之一：配方法与换元法 把代数式通过凑配等手段，得到完全平方式，再运用完全平方式是非负数这一性质达到增加问题的条件的目的，这种解题方法叫配方法． 所谓换元法，就是在一个比较复杂的数学式子中，用新的变元去代替原式的一个部分或改造原来的式子，使它简化，使问题易于解决。 【范例讲析】： 例1： 填空题： 1）．将二次三项式x 2+2x －2进行配方，其结果为 。 2）．方程x 2+y 2+4x －2y+5=0的解是 。 3）．已知M=x 2－8x+22，N=－x 2+6x －3，则M 、N 的大小关系为 。 例2.已知△ABC 的三边分别为a 、b 、c ，且a 2+b 2+c 2=ab+bc+ac ，则△ABC 的形状为 。 例3.解方程：422740x x --= 【闯关夺冠】 1.已知13x x +=．则221x x +的值为__________． 2．若a 、b 、c 是三角形的三边长，则代数式a 2 –2ab+b 2 –c 2的值 （ ） A 大于零 B 等于零 C 小于零 D 不能确定 3已知：a 、b 为实数，且a 2+4b 2－2a+4b+2=0，求4a 2－ b 1的值。 4. 解方程： 211( )65()11 x x +=--
中考数学专题复习之二：待定系数法 对于某些数学问题，若得知所求结果具有某种确定的形式，则可研究和引入一些尚待确定的系数(或参数)来表示这样的结果．通过变形与比较．建立起含有待定字母系数(或参数)的方程(组)，并求出相应字母系数(或参数)的值，进而使问题获解．这种方法称为待定系数法． 【范例讲析】： 【例1】二次函数的图象经过A(1，0)、B(3，0)、C(2，－1)三点． (1)求这个函数的解析式． (2)求函数与直线y=－x+1的交点坐标． 【例2】一次函数的图象经过反比例函数x y 8- =的图象上的A 、B 两点，且点A 的横坐标与点B 的纵坐标都是2。 （1）求这个一次函数的解析式； （2）若一条抛物线经过点A 、B 及点C （1，7），求抛物线的解析式。 【闯关夺冠】 1.已知：反比例函数和一次函数图象的一个交点为（－3，4），且一次函数的图象与x 轴的交点到原点的距离为5，分别确定这两个函数的解析式。 2、如图所示，已知抛物线的对称轴是直线x=3，它与x 轴交于A 、B 两点，与y 轴交于C 点，点A 、C 的坐标分别是(8，0)、(0，4)，求这个抛物线的解析式．
2019中考英语专题复习—七选五阅读及答案 一、七选五阅读命题类型：（考察角度） 1）主旨概括句：多位于标题或段首处，考察主旨和段首大意 2）过渡性句子：多位于段落中间或段首处，承上启下，考察文章内在结构 3）细节性句子：多位于段落中间或段尾处，考察上下文逻辑意义。 二、解题策略：总的原则: “分析篇章结构，把握全篇文脉是阅读填空题解题的关键”。（1）越过空格，通读全文，了解大意。 （2）通读选项，抓住其关键词语，明确各选项的大致意思， （3）回到空格处，根据空格在段落中的位置判断设空类型。（主旨；过渡；细节） （4）定位选项。根据文章整体结构与具体内容，将选项填入文中。 （5）确定排除，研究多余选项，确定排除理由，最终确定答案。 三、细节性问题(多位于段落中间）。 设题涉及具体的细节信息，或前后呼应，或进行补充说明。一般根据前后句之间的关系即可判断。注意三个衔接： ?1，词汇衔接 ?2，逻辑衔接 ?3，结构衔接 1)同词出现法 词汇同现是指属于同一词汇或者跟此词汇相关同一领域的词汇在文章中共同出现，达到语义衔接的目的。你可以在选项中找到与此词汇最接近的词，从而达到快而准。一般来说，上下文中词汇联系越接近，上下文的衔接关系越紧密 2)词汇复现法
复现，是保证文章前后衔接而经常使用的一种写作手段，即作者在文章上下文不同的位置对同一个概念进行重复描述。复现关系，主要是指同义词复现、近义词复现、反义词复现等。双保险：上下文再核实一下。 3) 代词线索 英语表达中代词出现的频率极高，代词的作用无非是指代前面提及的名词或形容词概念，巧妙利用这样的指代关系和根据代词的单复数差异可以准确而快速地解题。 4) 逻辑关系衔接 解答议论文体的阅读填句题,首先要把握好所论述的中心问题.通常所挖空缺与选项都以一条主线为主。其次,此类文章中经常出现一些逻辑关系词,对于理解文章与判定答案很有帮助。七选五阅读理解题的解题技巧: ◆速读全文，关注每段首尾句，了解大意知主题 ◆浏览选项，理解全篇逻辑关系,找出关键词 ◆运用上下文所重复的关键词推断 ◆利用同义词和近义词关系 ◆利用词的上下义关系 ◆利用反义词、过渡词关系 ◆理清结构与逻辑关系，确定答案 A What’s your favorite weather?
