1、back an animal that had disappeared from its homeland.This is a good example of friendship and understanding between these two countries.Unit 5The band that wasntHave you ever wanted to be part of a band as a famous singer or musicians? Have you ever dreamed of playing in front of thousands of peopl
2、e at a concert, at which everyone is clapping and appreciating your music? Do you sing Karaoke and pretend you are a famous singer like Song Zuying or Liu Huan? To be honest, a lot of people attach great importance to becoming rich and famous. But just now do people form a band?Many musicians meet a
3、nd form a band because they like to write and play their own music.They may start as a group of high-school students, for whom practising their music in someones house is the first step to fame. Sometimes they may play to passers-by in the street or subway so that they can earn some extra money for
4、themselves or to pay for their instruments. Later they may give performances in pubs or clubs, for which they are paid in cash. Of course they hope to make records in a studio and sell millions of copies to become millionaires!However, there was one band that started in a different way. It was calle
5、d the Monkees and began as a TV show. The musicians were to play jokes on each other as well as play music, most of which was based loosely on the Beatles. The TV organizer had planned to find four musicians who could act as well as sing. They put an advertisement in a newspaper looking for rock mus
6、icians, but they could only find one who was good enough. They had to use actors for the other three members of theband.As some of these actors could not sing well enough, they had to rely on other musicians to help them. So during the broadcasts they just pretended to sing. Anyhow their performance
7、s were humorous enough to be copied by other groups. They were so popular that their fans formed clubs in order to get more familiar with them. Each week on TV, the Monkees would play and sing songs written by other musicians. However, after a year or so in which they became more serious about their
8、 work, the Monkees started to play and sing their own songs like a real band. Then they produced their own records and started touring and playing their own music. In the USA they became even more popular than the Beatles and sold even more records. The band broke up about 1970, but happily they reu
9、nited in the mid-1980s. They produced a new record in 1996, with which they celebrated their former time as a real band.Freddy the frog（）Not long after Freddy and the band became famous, they visited Britain on a brief tour. Fans showed their devotion by waiting for hours to get tickets for their co
10、ncerts . Freddy was now quite confident when he went into a concert hall. He enjoyed singing and all the congratulations afterwards! His most exciting invitation was to perform on a TV programme called “ Top of pops “. He had to go to London, wear an expensive suit and give a performance to a TV cam
11、era. It felt very strange. But as soon as the programme was over, the telephones which were in the same room started ringing. Everybody was asking when they could see Freddy and his band again. They were truly stars.Then things went wrong. Freddy and his band could not go out anywhere without being
12、followed. Even when they wore sunglasses or beards people recognized them. Fans found them even when they went into toilet. They tried to hide in the reading rooms of libraries, but it was useless. Someone was always there! Their personal life was regularly discussed by people who did not know them
13、but talked as if they close friends. At last feeling very upset and sensitive, Freddy and his band realized that they must leave the country before it became too painful for them. So they left Britain, to which they were never to return, and went back to the lake.必修三Unit 1Festivals and celebrationsF
14、estivals 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 fo
15、od was difficult to find, especially during the cold winter months. Todays 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 satisfy the ancestors, who might return either to help or
16、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 this will lead the ancestors back to earth. In Mexico, people celebrate the Day of the Dead in early Novemver. On
17、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 childrens festival, when they
18、can dress up an go to their neighbours homes to ask for sweets. If the neighbours do not give any sweers, the children might play a trick on them.Fetivals to Honour PeopleFestivals can also be held to honour famous people. The Dragon Boat Festival in China honours the famous ancient poet, Qu Yuan. I
19、n the USA, Columbus Day is in memory of the arrival of Christopher Columbus in the New World. India has a national festival on October 2 to honour Mohandas Gandhi, the leader who helped gain Indias independece from Britain.Harvest FestivalsHarvest and Thanksgiving festival can be very happy events.
20、People are grateful because their food is gathered for the winter and the agricultural work is over. In European countries, people will usually decorate churches and town halls with flowers and fruit, and will get together to have meals. Some people might win awards for their farm produce, like the
21、biggest watermelon or the most handsome rooster. China and Japan have mid-autumn festivals, when people admire the moon and in China, enjoy mooncakes.Spring FestivalsThe most energetic and important festivals are te ones that look forward to the end of winter and to the coming of spring. At the Spri
22、ng Festival in China, people eat dumpings ifsh and meat and may give children lucky money in red paper. There are dragon dances and carnivals , and families celebrate the Lunar New Year together. Some Western countries have very exciting carnicals, which take place forty days before Easter, usually
23、in February. These carnivals 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 for Chiristians around the world. It celebrates the return of Jesus from the dead and the coming of spring an
24、d new life. Japans Cherry Blossom Festical happens a little later. The country, covered with cherry tree flowers, looks as though it is covered with pink snow.People love to get together to eat, drink and have fun with each other. Festivals let us enjoy life, be proud of our customs and forget ou wo
25、rk for a little while.A Sad Love StoryLi Fang was heart-broken. It was Valetines Day and Hu Jin had said she would meet him at the coffee shop after work. But she didnt turn up. She could be with her friends right now laughing at him. She said she would be there at seven o clock, and he thought she
26、would keep her word. He had looked forward to meeting her all day, and now he was alon with his roses and chocolates, like a fool. Well, he ws not going to hold his breath for her to apologize. He would drown his sadness in coffee.It was obvious that the manager of the coffee shop was waiting for Li
27、 Fang to leave he wiped the tables, then sat down and turned on the TV just what Li Fang needed! A sad Chinese story about lost love.The randdaughter of the Goddess of Heaven visited the earth. Her name was Zhinu, the weaving firl. While she was on earth she met the herd boy Niulang and they fell in
28、 love. ( “ Just like me and Hu Jin,” thought Li Fang.) They got married secretly, and they were very happy. (“We could be like that, “ thought Li Fang.) When the Goddess of Heaven knew that her granddaughter was married to a human, she became very angry and made the weaving girl return to Heaven. Ni
29、ulang tried to follow her, but the river of stars, the Milky Way, stopped him. Finding that Zhinu was heart-broken, her grandmother finally decided to let the couple cross the Milky Way to meet once a year. Magipies make a bridge of their wings so the couple can cross the river to meet on the sevent
30、h day of the senveth lunar month. People in Chian hope that the weather will be fine on that day, because if it is raining, it means that zhinu is weeping and the couple wont be able to meet.The announcer said, “ This is the story of Qiqiao Festival. When foreigners hear about the story they call it
31、 a Chinese Valentines story. Its a fine day today, so I hope you can all meet the one you love.”As Li Fang set off for home, he thought , “ I guess Hu Jin doesnt love me. I just throw these flowers and chocolates away. I dont want them to remind me of her.” So he did.As he sadly passed the tea shop
32、on the corner on his wasy home, he heard a voice calling him. There was Hujin waving at him and calling, “Why are you so late? Ive been waiting for you for a long time! An I have a gift for you!”What would he do? He had thrown away her Valentine figes! She would never forgive him. This would not be

42、难点：圆柱体体积公式的推导教学用具：圆柱体学具、课件教学过程：一、 复习引新 1求下面各圆的面积(回答)。 (1)r=1厘米； (2)d=4分米； (3)C=6.28米。 要求说出解题思路。 2想一想：学习计算圆的面积时，是怎样得出圆的面积计算公式的?指出：把一个圆等分成若干等份，可以拼成一个近似的长方形。这个长方形的面积就是圆的面积。 3提问：什么叫体积?常用的体积单位有哪些? 4已知长方体的底面积s和高h，怎样计算长方体的体积?(板书：长方体的体积=底面积高)二、探索新知1 根据学过的体积概念，说说什么是圆柱的体积。(板书课题)2 怎样计算圆柱的体积呢?我们能不能根据圆柱的底面可以像上面说
43、的转化成一个长方形，通过切、拼的方法，把圆柱转化为已学过的立体图形来计算呢，现在我们大家一起来讨论。 3公式推导。(有条件的可分小组进行) (1)请同学指出圆柱体的底面积和高。 (2)回顾圆面积公式的推导。(切拼转化) (3)探索求圆柱体积的公式。 根据圆面积剪、拼转化成长方形的思路，我们也可以运用切拼转化的方法把圆柱体变成学过的几何形体来推导出圆柱的体积计算公式。你能想出怎样切、拼转化吗?请同学们仔细观察以下实验，边观察边思考圆柱的体积、底面积、高与拼成的几何形体之间的关系。教师演示圆柱体积公式推导演示教具：把圆柱的底面分成许多相等的扇形(数量一般为16个)，然后把圆柱切开，照下图拼起来，(
44、图见教材)就近似于一个长方体。可以想象，分成的扇形越多，拼成的立体图形就越接近于长方体。 (4)讨论并得出结果。你能根据这个实验得出圆柱的体积计算公式吗?为什么?让学生再讨论：圆柱体通过切拼，圆柱体转化成近似的长方体。这个长方体的底面积与圆柱体的底面积相等，这个长方体的高与圆柱体的高相等。因为长方体的体积等于底面积乘以高，所以，圆柱体的体积计算公式是：圆柱的体积=底面积高(板书：圆柱的体积=底面积高)用字母表示：(板书：V=Sh) (5)小结。 圆柱的体积是怎样推导出来的?计算圆柱的体积必须知道哪些条件？ 4教学算一算 审题。提问：你能独立完成这题吗?指名一同学板演，其余学生做在练习本上。集体
45、订正：列式依据是什么?应注意哪些问题?最后结果用体积单位) 教学“试一试”小结：求圆柱的体积，必须知道底面积和高。如果不知道底面积，只知道半径r，通过什么途径求出圆柱的体积?如果知道d呢?知道C呢?知道r、d、C，都要先求出底面积再求体积。三、巩固练习 练习册练习四、课堂小结这节课学习了什么内容?圆柱的体积怎样计算，这个公式是怎样得到的?指出：这节课，我们通过转化，把圆柱体切拼转化成长方体，(在课题下板书：圆柱些长方体)得出了圆柱体的体积计算公式V=Sh。五、作业选用课时作业 六、随堂反思：第二课时教学目标：1进一步理解和掌握圆柱的体积计算公式，并能应用到实际解决问题中。2培养学生初步的空间观
