Is your schoolbag too heavy to carry? The e-schoolbag will help you.

It is said that e-schoolbags will be used in Chinese middle schools soon. In fact, the e-schoolbag should be called an e-textbook. It is a small computer for students. Heavy schoolbags have been a serious problem for them. But the e-schoolbag will change this situation. It is much lighter than a usual schoolbag. Also it is as small as a usual book, but it can hold all the things for study, such as a textbook, an exercise book and so on. They can be made into chips (芯片) that are

as small as a stamp. The students can read the text page by page on the screen, take notes, or even send e-mails to their teachers. All they have to do is to put the right chip into the e-schoolbag and press a button.

Some people say that e-schoolbags can be easily broken; some say e-schoolbags are bad for students' eyes. Only time can tell us the truth.

( ) 1. The e-schoolbag is ______.

C. E-schoolbags may be used instead of usual schoolbags.

D. E-schoolbags have come into use in China.

B. Answer the questions(根据短文内容回答下列问题)

Life in 30 years will be different because many changes will take place. But what will the changes be?

The population is growing fast. There will be more and more people in the world and most of them will live longer than before. Computers will be much smaller and more useful, and there will be at least one computer in every home. And computer study will be one of the most important subjects in school.

People will work fewer hours, and they will have more free time for sports, watching TV and travelling. Travelling will be much cheaper and easier. And more people will go to other countries for holidays.

There will be changes in our food, too. More land will be used for building new towns and houses. Then there will be less room for cows and sheep, so meat will be more expensive. Maybe no one

will eat it every day, instead they eat more vegetables and fruit. Maybe people will be healthier than now.

Work in the future will be different, too. Dangerous and hard work will be done by robots. Because of this, many people will not have enough work to do. This will be a problem.

七年级上册知识点总结

人教版数学七年级上册知识点总结 第一章有理数知识点总结 0的数叫做正数。 1. 0既不是正数也不是负数,是正数和负数的分界线,是整数,一、正数和负数自然数,有理数。 (不是带“—”号的数都是负数,而是在正数前加“—”的数。) 2.意义:在同一个问题上,用正数和负数表示具有相反意义的量。 概念整数:正整数、0、负整数统称为整数。 数:正分数、负分数统称分数。 (有限小数与无限循环小数都是有理数。) 注:正数和零统称为非负数,负数和零统称为非正数,正整数和零统称为非负 整数,负整数和零统称为非正整数。 ⑵按整数、分数分类: 正有理数正整数正整数 正分数整数0 零有理数负整数 负有理数负整数分数正分数 负分数负分数 1.概念:规定了原点、正方向、单位长度的直线叫做数轴。 三要素:原点、正方向、单位长度 2.对应关系:数轴上的点和有理数是一一对应的。 三、数轴 比较大小:在数轴上,右边的数总比左边的数大。 3.应用 求两点之间的距离:两点在原点的同侧作减法,在原点的两侧作加法。 (注意不带“+”“—”号)

代数:只有符号不同的两个数叫做相反数。 1.概念(0的相反数是0) 几何:在数轴上,离原点的距离相等的两个点所表示的数叫做相反数。 2.性质:若a与b互为相反数,则a+b=0,即a=-b;反之, 若a+b=0,则a与b互为相反数。 四、相反数 两个符号:符号相同是正数,符号不同是负数。 3.多重符号的化简 多个符号:三个或三个以上的符号的化简,看负号的个数,当 “—”号的个数是偶数个时,结果取正号 当“—”号的个数是奇数个时,结果取负号 1.概念:乘积为1的两个数互为倒数。 (倒数是它本身的数是±1;0没有倒数) 五、倒数 2.性质若a与b互为倒数,则a·b=1;反之,若a·b=1,则a与b互为倒数。 若a与b互为负倒数,则a·b=-1;反之,若a·b= -1则a与b互为负倒数。 a的点与原点的距离叫做数a的绝对值。 (若|a|=|b|,则a=b或a=﹣b) 一个负数的绝对值是它的相反数 的绝对值是0 a >0,|a|=a 反之,|a|=a,则a≥0 a = 0,|a|=0 |a|=﹣a,则a≦0 a<0,|a|=‐a 注:非负数的绝对值是它本身,非正数的绝对值是它的相反数。 a (a>0) 的数有2个,他们互为相反数。即±a。 |a|≥0。几个非负数之和等于 0,则每个非负数都等于0。故若|a|+|b|=0,则a=0,b=0 1.数轴比较法:在数轴上,右边的数总比左边的数大。 七、比较大小 2.代数比较法:正数大于零,负数小于零,正数大于一切负数。 两个负数比较大小时,绝对值大的反而小。

人教版七年级数学知识点归纳总结

第一章有理数 (一)正负数 1.正数:大于0的数。 2.负数:小于0的数。 3.0即不是正数也不是负数。 4.正数大于0,负数小于0,正数大于负数。 (二)有理数 1.有理数:由整数和分数组成的数。包括:正整数、0、负整数,正分数、负分数。可以写成两个整之比的形式。(无理数是不能写成两个整数之比的形式,它写成小数形式,小数点后的数字是无限不循环的。如:π) 2.整数:正整数、0、负整数,统称整数。 3.分数:正分数、负分数。 (三)数轴 1.数轴:用直线上的点表示数,这条直线叫做数轴。(画一条直线,在直线上任取一点表示数0,这个零点叫做原点,规定直线上从原点向右或向上为正方向;选取适当的长度为单位长度,以便在数轴上取点。) 2.数轴的三要素:原点、正方向、单位长度。 3.相反数:只有符号不同的两个数叫做互为相反数。0的相反数还是0。4.绝对值:正数的绝对值是它本身,负数的绝对值是它的相反数;0的绝对值是0,两个负数,绝对值大的反而小。 (四)有理数的加减法 1.先定符号,再算绝对值。

2.加法运算法则:同号相加,到相同符号,并把绝对值相加。异号相加,取绝对值大的加数的符号,并用较大的绝对值减去较小的绝对值。互为相反数的两个数相加得0。一个数同0相加减,仍得这个数。 3.加法交换律:a+b= b+ a 两个数相加,交换加数的位置,和不变。 4.加法结合律:(a+b)+ c = a +(b+ c )三个数相加,先把前两个数相加,或者先把后两个数相加,和不变。 5. a?b = a +(?b)减去一个数,等于加这个数的相反数。 (五)有理数乘法(先定积的符号,再定积的大小) 1.同号得正,异号得负,并把绝对值相乘。任何数同0相乘,都得0。2.乘积是1的两个数互为倒数。 3.乘法交换律:ab= b a 4.乘法结合律:(ab)c = a (b c) 5.乘法分配律:a(b +c)= a b+ ac (六)有理数除法 1.先将除法化成乘法,然后定符号,最后求结果。 2.除以一个不等于0的数,等于乘这个数的倒数。 3.两数相除,同号得正,异号得负,并把绝对值相除,0除以任何一个不等于0的数,都得0。 (七)乘方 1.求n个相同因数的积的运算,叫做乘方。写作a n 。(乘方的结果叫幂,a 叫底数,n叫指数) 2.负数的奇数次幂是负数,负数的偶次幂是正数;0的任何正整数次幂都是

人教版七年级语文知识点总结(完结篇)

第一单元 1.《春》朱自清 一、作者介绍 朱自清(1898——1948),原名自华,字佩弦,号秋实,后改名自清,是中国现代著名散文家、诗人、学者、民主战士。原籍浙江绍兴,后定居扬州,故自称“扬州人”。1923年发表长诗《毁灭》,震动诗坛。他的散文朴素缜密,清隽沉郁,以语言洗练、文笔清丽著称,极富有真情实感。代表作诗文集《踪迹》,散文集有《背影》《欧游杂记》《你我》,文艺论著有《诗言志辨》《论雅俗共赏》,散文代表作有《荷塘月色》《绿》《背影》《桨声灯影里的秦淮河》等。 二、词语解释 ①欣欣然:欢欢喜喜的样子 ②朗润:明朗润泽 ③赶趟儿:原意指赶得上,这里的意思是各种果树争先恐后地开花 ④酝酿:原意是造酒,这里是说各种气息混合在空气里,像发酵似的,越来越浓 ⑤婉转:形容声音抑扬动听 ⑥花枝招展:比喻姿态优美。招展,迎风摆动 ⑦一年之计在于春:一年的打算在春天。意思是,春天是一年的开始,应该把全年要做的事情及早安排好 ⑧吹面不寒杨柳风:出处南宋的志南和尚《绝句》:古木阴中系短篷,杖藜扶我过桥东。沾衣欲湿杏花雨,吹面不寒杨柳风。 三、中心思想 这是一篇优美的写景抒情散文,描绘了大地春回、生机勃发的动人景象。通过春草图、春花图、春风图、春雨图和迎春图五幅主要图画,赞美春的活力带给人以希望和力量表达了作者热爱生活、积极进取、奋发向上的精神风貌。

2.《济南的冬天》老舍 一、作者简介 老舍,满族,原名舒庆春,字舍予,笔名“舍予”“老舍”(老舍是他最常用的笔名),北京人,中国现代著名作家,人民艺术家。主要作品有小说《骆驼祥子》《四世同堂》,话剧《茶馆》《龙须沟》等,收在《老舍文集》里。“舍予”是“舒”字的分拆:舍,舍弃;予,我。含有“舍弃自我”,亦即“忘我”的意思。“舍予”“老舍”,就是他一生忘我精神的真实写照。 二、词语解释 ①响晴:(天空)晴朗无云 ②温晴:温暖晴朗 ③着落:可以依靠或指望的来源 ④空灵:灵活而不可捉摸 ⑤秀气:清秀。这里形容小山秀美小巧 ⑥澄清:这里指水清澈见底 ⑦贮蓄:存放,储藏 三、本文的中心思想是什么? 在这篇写景散文中,作者抓住济南地处北国而冬季气候"温晴"的特点,描绘了济南的阳光、小雪、山山水水,抒发了作者热爱祖国自然风光的挚爱深情。 3.雨的四季刘湛秋 有一支没有音符的乐曲,一点一滴,奏出欢快合谐而又美丽的旋律,只有细心倾听的人,才了解它的深意。这就是雨,它似歌、如诗、像画,春雨柔美,夏雨猛烈,秋雨清凉,冬雨冷静,各式各样的雨滋润着万物也浸润着人的心灵。被誉为中国抒情诗之王的当代诗人刘湛秋的美文《雨的四季》就是这样一首四季雨歌。

人教版七年级下册数学知识点总结

第五章相交线与平行线 一、相交线 相交线:如果两条直线只有一个公共点,就说这两条直线相交,该公共点叫做两直线的交点。如直线AB、CD相交于点O。 A D C O B 对顶角: 邻补角:有一条公共边,角的另一边互为反向延长线.满足这种关系的两个角, 互为领补角。 邻补角与补角的区别与联系 ? 1.邻补角与补角都是针对两个角而言的,而且数量关系都是两角之和为180° ? 2.互为邻补角的两个角一定互补,但是互为补角的两个角不一定是邻补角

即:互补的两个角只注重数量关系而不谈位置,而互为邻补角的两个角既要满足数量关系又要满足位置关系。 领补角与对顶角的比较 二、垂线 垂直:当两条直线相交所成的四个角中,有一个角是直角时,这两条直线互相垂直,其中一条直线叫另一条直线的垂线,它们的交点叫垂足。 从垂直的定义可知,判断两条直线互相垂直的关键:要找到两条直线相交时四个交角中一个角是直角。 垂直的表示:用“⊥”和直线字母表示垂直 b a O

例如:如图,a 、b 互相垂直,O 叫垂足.a 叫b 的垂线, b 也叫a 的垂线。则记为:a ⊥b 或b ⊥a ; 若要强调垂足,则记为:a ⊥b, 垂足为O. 垂直的书写形式: 如图,当直线AB 与CD 相交于O 点,∠AOD=90°时,AB ⊥CD ,垂足为O 。 书写形式: ∵∠AOD=90°(已知) ∴AB ⊥CD (垂直的定义) 反之,若直线AB 与CD 垂直,垂足为O ,那么,∠AOD=90°。 书写形式: ∵ AB ⊥CD (已知) ∴ ∠AOD=90° (垂直的定义) 应用垂直的定义:∠AOC=∠BOC=∠BOD=90° 垂线的画法: 如图,已知直线 l 和l 上的一点A ,作l 的垂线. 则所画直线AB 是过点A 的直线 l 的垂线. 工具:直尺、三角板 1放:放直尺,直尺的一边要与已知直线重合; 2靠:靠三角板,把三角板的一直角边靠在直尺上; D O C B B A l

上海版-牛津英语-七年级阅读理解指导与练习

阅读理解是考试中必不可少的题型 做阅读理解有哪些不可缺少的步骤? (一)如果文章较短,可以先浏览文章,再读后面所设问题;如若文章较长,可先读所设问题,然后再回过头来阅读文章。 (二)读文章时,要掌握其大意并重视短文中开头和结尾的段落或句子的含义。因为它们往往是文章中心的概括和总结。同时还要注意事情的起因、过程、结果及发生的时间、地点等细节性的问题。 (三)复读文章,核对答案。 阅读中的题目通常分为这几类: 1、信息题。这类题往往比较简单,可以在文章中直接找到答案。 2、解释题。这类题要求对文中的个别词、词组或句子作出解释。 3、概括题。这类题是对一段或者整篇内容的总结。 4、推理题。这类题须对文章进行分析后得出答案。 D If you go into the forest with friends, stay with them .If you don’t, you may get lost.

最新人教版七年级语文下册知识点归纳总结 第一单元梳理 一、课文内容梳理 《邓稼先》一文不同于一般的人物传记,更不同于一般写人的记叙文,而是以中华几千年文化为背景, 以近一百多年来民族情结、五十年朋友深情为基调,用饱含感情的语言介绍了一位卓越的科学家、爱国者。 文章的形式是“散”的,它没有系统介绍邓稼先的事迹,文中还插入了古文、诗歌、电报等内容,但主题 是集中的:中华几千年优秀传统文化孕育了邓稼先,邓稼先这类杰出人物又使中华民族自立于世界民族之 林。 《说和做——记闻一多先生言行片段》不是人物传记,却记叙了闻一多先生的主要事略,表现了他的 崇高品格,高度赞扬了他的革命精神。这篇文章前半部分写闻一多先生前期怎样为了探索救国救民的出路 而潜心学术,不畏艰辛,废寝忘食,十数年如一日,终于在学术上取得累累硕果。着力表现闻一多先生是 “卓越的学者”。后半部分写闻一多先生参加游行示威,起草政治传单,做群众大会的演说,表现了闻一 多先生为求民主反独裁,宁愿付出生命的代价的高尚人格。着力表现闻一多先生是“大无畏的革命家”。 《回忆鲁迅先生( 节选) 》这篇散文是鲁迅的学生萧红通过十五个片断来描述先生生活中的点滴,短的 一两行,长的八十多行,内容涉及鲁迅的饮食起居、待人接物、读书写作、休闲

娱乐,特别是外人知之甚

少的病中生活。文中的片断在内容上没有严格的逻辑顺序,这是一篇非常情绪化的文章。作者动笔之前对 于全篇的布局似乎漫不经心,全无预设。动笔之后,作者心底的感情如喷涌的泉水,飞湍的激流,尽情倾 泻挥洒,形诸笔墨而成为艺术结晶。另一个引人注目之处恰恰是通过女性作者的细心体察,敏锐捕捉到了 鲁迅先生身上许多有灵性的生活细节,表现出鲁迅的个性、情趣、魅力、气质,从细微处显示了鲁迅的伟 大思想和人格。 《孙权劝学》记事简练。全文只写了孙权劝学和鲁肃“与蒙论议”两个片断,即先交代事情的起因, 紧接着就写出结果,而不写出吕蒙如何好学,他的才略是如何长进的。写事情的结果,也不是直接写吕蒙 如何学而有成,而是通过鲁肃与吕蒙的对话生动地表现出来。写孙权劝学,着重以孙权的劝说之言,来表 现他的善劝,而略去吕蒙的对答,仅以“蒙辞以军中多务”一句写吕蒙的反应,并仅以“蒙乃始就学”一 句写吕蒙接受了劝说;写鲁肃“与蒙论议”,着重以二人富有风趣的一问一答,来表现吕蒙才略的惊人长 进,而略去二人“论议”的内容,并仅以“肃遂拜蒙母,结友而别”一句作结。 二、单元字词汇总 1.邓稼先 至死不懈xi a:懈,放松。蓬断草枯:形容环境恶劣署shǔ名:在书信、文件或文稿上,
