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-b1的值。
4. 解方程: 211()65()11x x +=--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xy 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。

2023年中考语文二轮复习专题:九年级文学类文本阅读理解专项训练--部编人教版九年级总复习

2023年中考语文二轮复习专题:九年级文学类文本阅读理解专项训练部编人教版九年级总复习九年级文学文本阅读理解专项训练(含答案)我的奶奶文浩①……奶奶去了,想起奶奶,就是一串关于辛劳、承受和奉献的记忆,如同寒冬雪花,一片片,一层层,覆盖了我的童年,我的求学,我的大家庭。
②我对奶奶的记忆是从童年开始的。
当时,我和妹妹是龙凤胎,一出生,整个大家族又喜又忧,喜是自然的,龙凤双胞胎本是老天爷送来的“一儿一女一枝花”。
可是,我们老家还有一个迷信说法,说龙凤胎前世是夫妻,出生以后很难养大成人,偏偏那时农村很多双胞胎都夭折一个,这个迷信说法就更有市场了。
所以,我奶奶在左思右想之后,决定来我家,帮助她的儿子儿媳带两个宝贝孙子。
那年我奶奶56岁,面色红润,手脚麻利,给孩子洗衣服做饭换尿片打包裙喂饭吃,样样比我妈妈厉害。
为了看护我们的成长,她老人家又得义无反顾地耗尽她余下27年的心血,时时刻刻,点点滴滴。
她累得身体佝偻,左手变形,手上和脚上爬满了无情岁月刻下的松树皮一样的皱纹。
那些点滴穿透了我的记忆,深入到我的灵魂。
③那年我三岁,家还在沅江河堤边,起了龙卷风,将房顶的石棉瓦掀起好几块,直接扔到河堤上,毫不客气地把房子撕个粉碎,嚼间倒塌。
灾难发生的时候,妈正把我抱在怀里,靠近前门,见势不妙,慌忙夺门而出。
奶奶、妹妹加上邻家一个小孩三人都在后房,门没有开,奶奶来不及抱着两个小孩跑脱,只好把大一点的邻家小孩寒到床下。
把妹妹抱在怀中也往床下钻,无奈床下杂物太多,哪里容得下三个人,奶奶就佝偻着身躯然后挺起腰,死命护着妹妹,腰板上挨了砖块好几下,纹丝不动,直到灾难过后。
奶奶因此留下了一身的腰伤,留下了妹妹的性命,留给我们心中永远难忘的记忆,成了藏在我们内心深处的疼痛。
④再大些,我调皮,不好好吃饭,奶奶只好拿个搪瓷大碗跟我到处跑,“逼我”多吃几口。
可惜半大小孩总是顽劣不化,送到口中的饭莱嚼都懒得嚼就如数吐出,奶奶只好把饭菜在口中嚼碎,然后哄我吃下。

实战导引·点迷津
(2023 •新高考全国 I卷C) Reading Art: Art for Book Lovers is a celebration of an everyday object—the book, represented here in almost three hundred artworks from museums around the world.The image of the reader appears throughout history, in art made long before books as we now know them came into being.In artists' representations of books and reading, we see moments of shared humanity that go beyond culture and time.
Continued developments in communication technologies were once believed to make the printed page outdated.From a 21st-century point of view, the printed book is certainly ancient, but it remains as interactive as any battery-powered e-reader.To serve its function, a book must be activated by a user: the cover opened, the pages parted, the contents reviewed, perhaps notes written down or words underlined.And in contrast to our increasingly networked lives where the information we consume is monitored and tracked, a printed book still offers the chance of a wholly private, “off-line” activity.
新教材适用2024版高考英语二轮总复习第2部分阅读能力突破篇专题1阅读理解专题模拟训练主旨大意类

主旨大意类A(2023·湖南省岳阳市高三二模)At all hours of the day, white-aproned bakers occupy themselves in working in the Hot Bread Kitchen, throwing flour across butcher-block tables, filling metal trays with hand-shaped bread, and shifting steaming, fresh bread to cooling shelves.The only bodies at rest in this New York City bakery are pans with bread, waiting to be sent into the oven.The skilled bakers turn out around 25 varieties ranging from classic French baguettes to crisp Armenian lavash crackers—which they sell at farmers' markets and gourmet stores.But Hot Bread Kitchen is more than a bakery: It's a nonprofit designed to give foreign-born women the skills and support they need to establish careers in the culinary arts.Overseeing daily operation of the place—and often rolling up her own shirt sleeves to involve in—is 35-year-old founder and CEO Jessamyn Rodriguez.By mixing her lifelong passion for society with great food, Rodriguez says she has created her dream job.In 2008, Rodriguez launched the bakery in the small Brooklyn apartment she shared with roommates, hiring two immigrant women as her first bakers.“I was definitely breaking new ground, and we faced a lot of skeptics,” she says of those early days.“But for every person who questioned it, there were five people who were interested in supporting us.” Today, Hot Bread Kitchen employs a staff of 35 and occupies a nearly 5,000-square-foot space in La Marqueta, a public market in East Harlem.The women who bake and package Hot Bread Kitchen's offerings range in age from 21 to 60.Coming from lands such as Haiti, Nepal, and the Dominican Republic, some have lived in the U.S.for as little as a year.Others, including production manager Antonia Garcia, who is originally from Mexico, have called America home for more than a decade.These women's diverse homelands are reflected in many of the bakery's products, like heritage tortillas and the wildly popular m'smen, a buttery bread.The program has far surpassed Rodriguez's original hopes.Since its humble beginnings, Hot Bread Kitchen has trained 27 women from 12 countries.They receive paid, on-the-job experience, as well as courses in bakery sciences, and English as part of a yearlong training program.1.What does the first paragraph mainly talk about?A.Constant activity of skilled workers.B.Varieties of fresh baked goods.C.Many different types of equipment used in bakeries.D.Difficult working conditions of bakery employees.2.Which of the following can best describe Jessamyn Rodriguez?A.Adventurous and modest.B.Ambitious and gifted.C.Hard-working and courageous.D.Devoted and stubborn.3.How does the author establish the diversity of Hot Bread Kitchen?A.By describing the courses offered to employees.B.By introducing the backgrounds of the employees.C.By describing the bakery's location at La Marqueta.D.By introducing the bakery's development since 2008.4.What is the main idea of the article?A.Employees from diverse homelands produce various products.B.The hardworking women have helped Hot Bread Kitchen develop quickly.C.Rodriguez became a successful baker after establishing Hot Bread Kitchen.D.Hot Bread Kitchen provides professional opportunities for immigrant women.【语篇解读】本文是一篇说明文。

Wickenden is a very good storyteller.The sweep of the land and the stoicism (坚忍) of the people move her to some beautiful writing.Here is a picture of Dorothy Woodruff, on her horse, looking down from a hill top: “When the sun slipped behind the mountains, it shed a rosy glow all around them.Then a full moon rose.The snow was marked only by small animals: foxes, coyotes, mice, and varying hares, which turned white in the winter.”

【解题示范】 第一步:阅读文章,概括文章大意。文章主要介绍 了一种会识别形状的凤头鹦鹉;
第二步:分析各选项,进行斟酌判断,揣摩哪个选项能准确概括主 旨。通读全文,再结合第一段“Coffinʼs cockatoos, a kind of small parrot native to Australasia, have been shown to have similar shaperecognition abilities to a human two-year-old.(科芬的凤头鹦鹉是一种原 产于大洋洲的小鹦鹉,它的形状识别能力与两岁的人类相似。)”可知, 本 文 主 要 介 绍 了 会 识 别 形 状 的 凤 头 鹦 鹉 。 选 项 “Cockatoos: Skilful Shape-Sorters (凤头鹦鹉:识别形状的熟练工)”符合文意,最适合作为 本文标题。故选D。
