导入新课
情境导入
在日常生活中，我们最熟悉、最常用的是十进制，据说这与古人曾以手指计数有关，爱好天文学的古人也曾经采用七进制、十二进制、六十进制，至今我们仍然使用一周七天、一年十二个月、一小时六十分的历法.今天我们来学习一下进位制.
推进新课
新知探究
提出问题
（1）你都了解哪些进位制？
（2）举出常见的进位制.
（3）思考非十进制数转换为十进制数的转化方法.
（4）思考十进制数转换成非十进制数及非十进制之间的转换方法.
活动：先让学生思考或讨论后再回答，经教师提示、点拨，对回答正确的学生及时表扬，对回答不准确的学生提示引导考虑问题的思路．
讨论结果：
（1）进位制是人们为了计数和运算方便而约定的计数系统，约定满二进一，就是二进制；满十进一，就是十进制；满十二进一，就是十二进制；满六十进一，就是六十进制等等.也就是说：“满几进一”就是几进制，几进制的基数（都是大于1的整数）就是几.
（2）在日常生活中，我们最熟悉、最常用的是十进制，据说这与古人曾以手指计数有关，爱好天文学的古人也曾经采用七进制、十二进制、六十进制，至今我们仍然使用一周七天、一年十二个月、一小时六十分的历法.
（3）十进制使用0~9十个数字.计数时，几个数字排成一行，从右起，第一位是个位，个位上的数字是几，就表示几个一；第二位是十位，十位上的数字是几，就表示几个十；接着依次是百位、千位、万位……
例如：十进制数3 721中的3表示3个千，7表示7个百，2表示2个十，1表示1个一.于是，我们得到下面的式子：
3 721=3×103+7×102+2×101+1×100.
与十进制类似，其他的进位制也可以按照位置原则计数.由于每一种进位制的基数不同，所用的数字个数也不同.如二进制用0和1两个数字，七进制用0~6七个数字.
一般地，若k是一个大于1的整数，那么以k为基数的k进制数可以表示为一串数字连写在一起的形式
a n a n-1…a1a0（k）（0＜a n＜k，0≤a n-1，…，a1，a0＜k).
其他进位制的数也可以表示成不同位上数字与基数的幂的乘积之和的形式，如
110 011（2）=1×25+1×24+0×23+0×22+1×21+1×20，
7 342（8）=7×83+3×82+4×81+2×80.
非十进制数转换为十进制数比较简单，只要计算下面的式子值即可：
a n a n-1…a1a0(k)=a n×k n+a n-1×k n-1+…+a1×k+a0.
第一步：从左到右依次取出k进制数a n a n-1…a1a0(k)各位上的数字，乘以相应的k的幂，k的幂从n开始取值，每次递减1，递减到0，即a n×k n,a n-1×k n-1,…,a1×k,a0×k0；
第二步：把所得到的乘积加起来，所得的结果就是相应的十进制数.
（4）关于进位制的转换，教科书上以十进制和二进制之间的转换为例讲解，并推广到十进制和其他进制之间的转换.这样做的原因是，计算机是以二进制的形式进行存储和计算数据的，而一般我们传输给计算机的数据是十进制数据，因此计算机必须先将十进制数转换为二
进制数，再处理，显然运算后首次得到的结果为二进制数，同时计算机又把运算结果由二进制数转换成十进制数输出.
1°十进制数转换成非十进制数
把十进制数转换为二进制数，教科书上提供了“除2取余法”，我们可以类比得到十进制数转换成k进制数的算法“除k取余法”.
2°非十进制之间的转换
一个自然的想法是利用十进制作为桥梁.教科书上提供了一个二进制数据与16进制数据之间的互化的方法，也就是先由二进制数转化为十进制数，再由十进制数转化成为16进制数. 应用示例
思路1
例1 把二进制数110 011(2)化为十进制数.
解：110 011(2)=1×25+1×24+0×23+0×22+1×21+1×20=1×32+1×16+1×2+1=51.
点评：先把二进制数写成不同位上数字与2的幂的乘积之和的形式，再按照十进制的运算规则计算出结果.
变式训练
设计一个算法，把k进制数a（共有n位）化为十进制数b.
算法分析：从例1的计算过程可以看出，计算k进制数a的右数第i位数字a i与k i-1的乘积a i·k i-1，再将其累加，这是一个重复操作的步骤.所以，可以用循环结构来构造算法.
算法步骤如下：
第一步，输入a，k和n的值.
第二步，将b的值初始化为0，i的值初始化为1.
第三步，b=b+a i·k i-1，i=i+1.
第四步，判断i＞n是否成立.若是，则执行第五步；否则，返回第三步.
第五步，输出b的值.
程序框图如下图：
程序：
INPUT “a,k，n=”；a，k，n
b=0
i=1
t=a MOD 10
DO
b=b+t*k^（i-1）
a=a\\10
t=a MOD 10
i=i+1
LOOP UNTIL i＞n
PRINT b
END
例2 把89化为二进制数.
解：根据二进制数“满二进一”的原则，可以用2连续去除89或所得商，然后取余数.具体计算方法如下：
因为89=2×44+1，44=2×22+0，
22=2×11+0，
11=2×5+1，
5=2×2+1，
2=2×1+0，
1=2×0+1，
所以
89=2×（2×（2×（2×（2×2+1）+1）+0）+0）+1
=2×（2×（2×（2×（22+1）+1）+0）+0）+1
=…=1×26+0×25+1×24+1×23+0×22+0×21+1×20
=1 011 001(2).
这种算法叫做除2取余法，还可以用下面的除法算式表示：
把上式中各步所得的余数从下到上排列，得到89=1 011 001(2).
上述方法也可以推广为把十进制数化为k进制数的算法，称为除k取余法.
变式训练
设计一个程序，实现“除k取余法”.
算法分析：从例2的计算过程可以看出如下的规律：
若十制数a除以k所得商是q0，余数是r0，即a=k·q0+r0，则r0是a的k进制数的右数第1位数.
若q0除以k所得的商是q1，余数是r1，即q0=k·q1+r1，则r1是a的k进制数的左数第2位数.
……
若q n-1除以k所得的商是0，余数是r n，即q n-1=r n，则r n是a的k进制数的左数第1位数.
这样，我们可以得到算法步骤如下：
第一步，给定十进制正整数a和转化后的数的基数k.
第二步，求出a除以k所得的商q，余数r.
第三步，把得到的余数依次从右到左排列.
第四步，若q≠0，则a=q，返回第二步；否则，输出全部余数r排列得到的k进制数.
程序框图如下图：
程序：
INPUT “a，k=”；a，k
b=0
i=0
DO
q=a\\k
r=a MOD k
b=b+r*10^i
i=i+1
a=q
LOOP UNTIL q=0
PRINT b
END
思路2
例1 将8进制数314 706(8)化为十进制数，并编写出一个实现算法的程序.
解：314 706(8)=3×85+1×84+4×83+7×82+0×81+6×80=104 902.
所以，化为十进制数是104 902.
点评：利用把k进制数转化为十进制数的一般方法就可以把8进制数314 706(8)化为十进制数.
例2 把十进制数89化为三进制数，并写出程序语句.
解：具体的计算方法如下：
89=3×29+2，
29=3×9+2，
9=3×3+0，
3=3×1+0，
1=3×0+1，
所以:89(10)=10 022(3).
点评：根据三进制数满三进一的原则，可以用3连续去除89及其所得的商，然后按倒序的顺序取出余数组成数据即可.
知能训练
将十进制数34转化为二进制数．
分析：把一个十进制数转换成二进制数，用2反复去除这个十进制数，直到商为0，所得余数（从下往上读）就是所求．
解：
即34(10)=100 010(2)
拓展提升
把1 234(5)分别转化为十进制数和八进制数．
解：1 234(5)=1×53+2×52+3×5+4＝194．
则1 234(5)=302(8)
所以，1 234(5)=194＝302(8)
点评：本题主要考查进位制以及不同进位制数的互化．五进制数直接利用公式就可以转化为十进制数；五进制数和八进制数之间需要借助于十进制数来转化．
课堂小结
（1）理解算法与进位制的关系.
（2）熟练掌握各种进位制之间转化.
作业
习题1.3A组3、4.
设计感想
计算机是以二进制的形式进行存储和计算数据的，而一般我们传输给计算机的数据是十进制数据，因此计算机必须先将十进制数转换为二进制数，再处理，显然运算后首次得到的结果为二进制数，同时，计算机又把运算结果由二进制数转换成十进制数输出.
因此学好进位制是非常必要的，另外，进位制也是高考的重点，本节设置了多种题型供学生训练，所以这节课非常实用.

普通高中课程标准实验教科书《英语》电子课本 Book 3 Unit 1 Festivals around the world B3U1P1-3 FESTIV ALS AND CELEBRATIONS Ancient Festivals Festivals and celebrations of all kinds are held everywhere. The most ancient festivals would celebrate the end of the cold weather, planting in spring and harvest in autumn. Other celebrations were held when hunters could catch animals. They would starve if food was difficult to find, so they celebrated when they had food. They lit fires and made music because they thought these festivals would bring a year of plenty. Festivals of the Dead Some festivals are held to honour the dead, or satisfy and please the ancestors, who could return either to help or to do harm. In Japan the festival is called Obon, when people should go to clean the graves and light incense in memory of their ancestors. They light lamps and play music because they think that this will lead the ancestors back to earth. In Mexico they have the Day of the Dead in early November. On this important feast day, people might eat food in shape of skulls, and cakes with “bones” on them. They offer food, flowers and gifts to the dead. The festival of Halloween had its origin as an event in memory of the dead. It is now a children’s festival, when they can go to their neighbours’ homes and ask for sweets. They dress up and try to frighten people. If they are not given anything, the children might play a trick. Festivals to Honour People Festivals can be held as an honour to famous people or to the gods. One of these is the Dragon Boat Festival in China, which honours the famous ancient poet, Qu Yuan. Another is Columbus Day in the USA, in memory of the arrival of Christopher Columbus in America. In India there is a national festival on October 2 to honour Mahatma Gandhi, the leader who helped gain India’s independence from Britain. Harvest Festivals Harvest and Thanksgiving festivals can be very happy events. People are grateful because their food is gathered for the winter ,and because a season of agricultural work is over. In European countries it is the custom to decorate churches and town halls with flowers and fruit, and people get together to have meals. Some people might win awards for their animals, flowers, fruits and vegetables, like the biggest watermelon or the most handsome rooster. In China and Japan there are mid-autumn festivals, when people admire the moon and give gift of mooncakes. Spring Festivals The most energetic and important festivals are the ones that look forward to the end of winter and to the coming of spring. At the Spring Festival in China, people eat dumplings, fish and meat, and may give children lucky money in the red paper. There are dragon dances and carnivals, and families celebrate the lunar New Year together. In some Western countries there are very exciting carnivals, which take place forty days before Easter, usually in February. They might include parades, dancing in the streets day and night, loud music and colourful clothing of all kinds. Easter is an important religious and social festival in Christian countries. It celebrates the return of Jesus for Christians and it also celebrates the coming of spring. In Japan, the Cherry Blossom Festival happens a little later. The country is covered with cherry tree flowers so that it looks as though it might be covered with pink snow. People love to get together to eat, drink and have fun with each others. Festivals let us enjoy life, be proud of our customs and forget our daily life for a little while.

新人教版高中英语课文译文 必修三 第一单元世界各地的节日 Reading 节日和庆典 自古以来，世界各地就有各种各样的节日和庆典。最古老的节日总是庆祝严寒的结束、春季的种植和秋天的收割。有时，在猎人捕获猎物后，也举行庆祝活动。在那个时代，如果食物难以找到，特别是在寒冷的冬月，人们就会挨饿。现在的节日有很多由来，一些是宗教上的，一些是季节性的，一些是纪念特殊的人和事件的。 亡灵节 有些节日，是为了纪念死者，或使祖先得到满足，因为祖先们有可能回到世上（给人们）提供帮助，也有可能带来危害。在日本的盂兰盆节，人们要扫墓、烧香，以缅怀祖先。他们还点起灯笼，奏响乐曲，因为他们认为这样做可以把祖先引回到世上。在墨西哥，亡灵节是在11月初。在这个重要的节庆日子里，人们会吃制成颅骨形状的食物和装点有“骨头”的蛋糕。他们向亡者祭献食物、鲜花和礼品。西方节日万圣节也源自人们古老的信念，认为亡者的灵魂会返回人间。万圣节如今成了孩子们的节日，这天他们可以乔装打扮上邻居家要糖吃。如果邻居什么糖也不给，那么孩子们就可以捉弄他们了。 纪念名人的节日 也有纪念名人的节日。中国的端午节（龙舟节）是纪念古代著名诗人屈
原的。美国的哥伦布日是纪念克里斯托弗.哥伦布发现“新大陆”的日子。印度 在10月2日有个全国性节日，纪念莫汉达斯.甘地，他是帮助印度脱离英国 而独立的领袖。 庆丰收的节日 收获与感恩节是十分喜庆的节日。越冬的粮食收集起来了，农活结束了，人们都心怀感激。在欧洲国家，人们通常用花果来装饰教堂和市政厅，在一 起聚餐。有些人还可能因为他们的农产品（参加各种评选）而获奖，比如最 大的西瓜或最帅的公鸡。中国和日本都有中秋节，这时人们会赏月。在中国，人们还品尝月饼。 春天的节日 最富生气而又最重要的节日，就是告别冬天、迎来春天的日子。中国人 过春节要吃饺子、鱼和肉，还要给孩子们送红纸包着的压岁钱。（他们）舞 龙灯、狂欢，全家人聚在一起欢庆阴历年。在一些西方国家有激动人心的狂 欢节，通常在二月，复活节前的四十天。狂欢节期间，人们穿着各种艳丽的 节日盛装，伴随着鼓噪的音乐，在街头游行，昼夜跳舞。复活节是全世界基 督徒的一个重要的宗教和公众节日。它庆祝耶稣复活，也欢庆春天和新生命 的到来。再晚些时候，日本就迎来了樱花节，（节日里）整个国度到处是盛 开的樱花。看上去就像覆盖了一层粉红色的雪。 人们喜欢聚在一起吃、喝、玩耍。节日让我们享受生活，让我们为自己的习俗而自豪，还可以暂时忘掉工作中的烦恼。 Using Language 一段伤心的爱情故事 李方的心都碎了。这天是情人节，胡瑾说她下班后会在咖啡馆和他见面

高一英语人教版必修三全册课文 Unit 1 Festivals around the world FESTIVALS AND CELEBRATIONS Festivals and celebrations of all kinds have been held everywhere since ancient times. Most ancient festivals would celebrate the end of cold weather, planting in spring and harvest in autumn. Sometimes celebrations would be held after hunters had caught animals. At that time people would starve if food was difficult to find, especially during the cold winter months. Today’s festivals have many origins, some religious, some seasonal, and some for special people or events. Festivals of the dead Some festivals are held to honour the dead or to satisfy the ancestors, who might return either to help or to do harm. For the Japanese festival Obon, people should go to clean graves and light incense in memory of their ancestors. They also light lamps and play music because they think that will lead the ancestors back to earth. In Mexico, people celebrate the Day of the Dead in early November. On this important feast day, people eat food in the shape of skulls and cakes with “bones” on them. They offer food, flowers and gifts to the dead. The Western holiday Halloween also had its origin in old beliefs about the return of the spirits of dead people. It is now a children’s festival, when t hey can dress up and go to their neighbours’ homes to ask for sweets. If the neighbours do not give any sweets, the children might play a trick on them.
