Unit 1

In September, 1941 the Nazi 1 (Germany)army was near St Petersburg. This was a time 2 the two countries were at war. However, before the Nazis could get to the summer palace, the Russians were only able to remove the furniture and small art objects from the Amber Room. But some of the Nazis secretly stole the Amber Room itself. In less than two days, 100,000 pieces of the room were put inside twenty-seven wooden boxes. There is no doubt 3 the boxes were then put on a train 4

Konigsberg, at that time a German city on the Baltic Sea. After that, what really happened to the Amber Room 5 (remain) a mystery.

While the search for the old room continues, the 6 (Russian) and Germans have built 7 new Amber Room at the summer palace. 8 (follow)old photos, the new room has been made to look much like the old one. In 9 spring of 2003, it was ready for the people of St Petersburg 10

高一必修一集合教案(精心)

必修一第一章预习教案(第1次) 1.1集合 1.1.1 集合的含义及其表示 教学目标:(1)初步理解集合的概念,知道常用数集及其记法; (2)初步了解“属于”关系的意义;(3)初步了解有限集、无限集、空集的意义; 教学重点:集合的含义与表示方法; 教学难点:运用集合的两种常用表示方法——列举法与描述法,正确表示一些简单的集合。 教学过程: 一、问题引入: 我家有爸爸、妈妈和我; 我来泉州市第九中学; 五中高一(1)班; 我国的直辖市。 分析、归纳上述各个实例的共同特征,归纳出集合的含义。 二、建构数学: 1.集合的概念:一般地,一定范围内某些确定的、不同的对象的全体构成一个集合(set )。集合常用大写的拉丁字母来表示,如集合A 、集合B …… 集合中的每一个对象称为该集合的元素(element ),简称元。集合的元素常用小写的拉丁字母来表示。如a 、 b 、 c 、p 、q …… 指出下列对象是否构成集合,如果是,指出该集合的元素。 (1)我国的直辖市; (2)五中高一(1)班全体学生;(3)较大的数 (4)young 中的字母; (5)大于100的数; (6)小于0的正数。 2.关于集合的元素的特征 (1)确定性:设A 是一个给定的集合,x 是某一个具体对象,则或者是A 的元素,或者不是A 的元素, 两种情况必有一种且只有一种成立。 (2)互异性:一个给定集合中的元素,指属于这个集合的互不相同的个体(对象),因此,同一集合中 不应重复出现同一元素。 (3)无序性:一般不考虑元素之间的顺序,但在表示数列之类的特殊集合时,通常按照习惯的由小到 大的数轴顺序书写。 3.集合元素与集合的关系用“属于”和“不属于”表示; (1)如果a 是集合A 的元素,就说a 属于A ,记作a ∈A (2)如果a 不是集合A 的元素,就说a 不属于A ,记作a ?A (“∈”的开口方向,不能把a ∈A 颠倒过来写) 4.有限集、无限集和空集的概念: 5.常用数集的记法:(1)非负整数集(自然数集):全体非负整数的集合记作N ,{} ,2,1,0=N (2)正整数集:非负整数集内排除0的集记作N *或N +{} ,3,2,1*=N (3)整数集:全体整数的集合记作Z , {} ,,, 210±±=Z (4)有理数集:全体有理数的集合Q , {}整数与分数=Q (5)实数集:全体实数的集合记作R {} 数数轴上所有点所对应的=R 注:(1)自然数集与非负整数集是相同的,也就是说,自然数集包括数0

高一信息技术基础知识点

信息技术 第一章信息与信息技术 1.1 信息及其特征 信息无处不在 1.物质、能源和信息(information)是人类社会的三大要素。P2 2.相同的信息,可以用多种不同的载体来表示和传播。不存在没有载体的信息。P3 信息的五个特征 1.信息的表示、传播、储存必须依附于某种载体,载体就是承载信息的事物。P3 2.信息是可以加工和处理的。信息也可以从一种形态转换成另一种形态。P3 3.信息可以脱离它所反映的事物被存储和保留和传播。 P3 4.信息是可以传递和共享的。信息可以被重复使用而不会像物质和能源那样产生损耗。P3 5.信息具有时效性。P3 1.2 信息的编码 1.信息的代码:把用来表示信息的符号组合叫做信息的代码。 2.计算机只能识别和处理由“0”、“1”两个符号组成的数字代码。或称计算机只能识别机器语言。 3.?诺依曼经典性建议:数据和程序都应采用二进制代码表示。 4.基本单位:字节,Byte简写“B”;最小单位:位,bit简写“b”。 5.1B=8b;1KB=1024Be;1MB=1024KB;1GB=1024MB。 6..进位制标识:二进制(B),十进制(D),十六进制(H) 7.二进制转换为十进制:按权展开。如(110101)2=1*25+1*24+1*22+1*20=53 8.十进制转换为二进制:除2取余法。如26=(1101)2 1.2.2字符编码: 1.计算机的英文字符编码采用ASCII码,即美国国家信息交换标准码(American Standard Code for Information Interchange)。该编码使用一个字节(byte)中的后7位二进制数,最左用“0填充”,可以表示27=128种编码。2.具体请见书本P6页。其中控制字符有34个,编码0-32和127;图形字符包括26个大写英文字母65-90、26个小写字母97-122、10个数字符号、32个标点及其他常用符号。 3.如(1)已知“A”的ASCII值为65,问“C”的ASCII值为多少? 答:“C”的ASCII值为65+2=67。 1.2.3汉字编码 1.汉字编码:汉字与西文字符一样,也是一种字符,在计算机也是以二进制代码形式表示的,这些代码称为汉字编码。2.汉字输入码:将汉字输入计算机的编码称为输入码,又称外码。 3.常用的输入码:音码、形码、音形码、形音码。 4.1个汉字占2字节,2字节=2*8位=16位;能提供216=65536个代码。1个字符(包括英文字符)占1字节。 5.汉字的编码按照GB2312-80标准,使用2字节编码。 6.会观察码:如用16进制显示了“PC个人电脑”这几个字的码:50 43 B8 F6 C8 CB B5 E7 C4 D4,问“个”字码是什么? 答:因为英文占1字节,中文占2字节,所以“PC个人电脑”占10字节,1字节=8位,所以总共80位,每4位二进制转换成1位十六进制,所以对应的“个”字码是:B8F6 1.2.4多媒体信息编码 1.声音信号是通过采样和量化实现模拟量的数字化。这个过程称“模数转换(A/D转换)”,承担转换任务的电路或芯片称为“模数转换器”简称ADC。 2.数模转换(D/A转换):即将数字化信号转换成模拟信号。 3.采样:就是按一定的频率,即每隔一小段时间,测得模拟信号的模拟量值。如CD采用的采样频率为44.1KHZ,即每秒钟要采样44100次。 4.采样频率越高,量化的分辨率越高,所得数字化声音的保真程度也越好,数据量也越大。 5.像素(pixel):图像数字化的基本思想是把一幅图像看成由许多彩色或各种级别灰度的点组成的,这些点按纵横排

教科版高中信息技术基础教案全集(必修) 1.1信息及其特征 一、教学内容分析和设计: “信息及其特征”是教育科学出版社的高一《信息技术基础》第一章第一节的内容。由于这个内容理论性较强,如果只是由教师来讲,学生可能会觉得枯燥,所以我准备在教师的引导下,举出现象,让学生进行探讨,然后归纳获得知识。有不足之处由教师或学生来补充。这样能让学生积极参与,活跃课堂气氛,既让学生学到知识,又培养了学生将学习与生活联系的习惯和自主学习的习惯。 二、教学对象分析: 知识的获取者是刚刚升入高中的学生,按照人的成长认知规律,学生对知识的获取开始由感性认识提升到理性认识。对于“信息”这一事物的认识,可以让他们从大量存在的现象中,发现并归纳出他们应该获得的知识。老师在此过程中起着引导的作用。 三、教学目标: 1、知识、技能目标:学生能够列举学习与生活中的各种信息,感受信息的丰富多彩性;举例说明信息的一般特征;培养学生分析问题、解决问题的能力。 2、过程、方法目标:培养学生从日常生活、学习中发现或归纳出新知识的能力。 3、情感态度与价值观目标:让学生理解信息技术对日常生活和学习的重要作用,激发对信息技术强烈的求知欲,养成积极主动地学习和使用信息技术、参与信息活动的态度。 四、教学重点: 1、信息特征的认识。 五、教学难点: 信息的含义。 六、教学方法 本节概念性强,实践性弱。采用讲授法,讨论法。 教学过程 谈话引入:同学们,信息技术这门课程,我们在初中阶段就已经学习。那么下面请同学们说一说,什么是信息?在我们日常生活中,你认为哪些属于信息?(举例) 生1:校园里铃声响,可以告诉我们信息:上课或下课。 生2:观看校运会,可以获得很多运动会赛场上的信息。 生3:从网上可以获得很多信息,如:学习资料、娱乐、新闻报导等。
