教學(xué)設(shè)計方案
Teaching Aims:
1.Get the Ss to grasp the main meaning of the whole text.
2..Ask the Ss to retell the text according to the questions.
Teaching procedures:
Step I Lead in
1.Check homework:
2.Show the map of Egypt and Africa
3.Get the Ss to respond the teacher’s questions:
T: Where is Africa ?
Where is Egypt ?
What is the river?
What is the dam ?
4.Ask one student to say something about Egypt.
Step II. Watch the video
1.可以在(探索)中查找關(guān)于埃及或金字塔或阿司旺大壩或阿布神廟.
2. 或者觀看本文的錄象資料。
Q: Is the High Dam a successful project ? (No)
Step III. Presentation
1.Read the text again and give them three questions ,
Qs: (1).Why was the High Dam built ?
(2).What is the High Dam like ?
(3).What were the problems with the building of the dam?
2.Discuss the answers in pairs.
3.Discuss the answers in class.
4.Try to help the Ss to be able to retell the text in their own words.
The possible answers:
1) The River Nile used to flood large areas every year and destroyed houses and crops. The new dam can control the waters of the Nile so that they run regularly all through the year. Electricity(20-50%of the electricity which Egypt needs )can be produced from the water which runs through the base of the dam.
2) The High Dam is the biggest in the world. It is 3830 meters long, 980 meters wide an the base and 40 meters wide at the top. The lake made by the dam is 500 kilometers long.
3) The water level of the lake was going to rise by 63 meters. It would be necessary to move 53000 people from their villages. A lot of important old temples dated from about 1250 BC would be covered by the water of the new lake so they would be in danger.
Step III Discuss
The Three Gorges Dam Project and the problems.
建議：提供有關(guān)三峽工程的一些數(shù)據(jù)（開始，進程，及規(guī)模）
三峽工程全稱為長江三峽水利樞紐工程。整個工程包括一座混凝重力式大壩，泄水閘，一座堤后式水電站，一座永久性通航船閘和一架升船機。三峽工程建筑由大壩。水電站廠房和通航建筑物三大部分組成。大壩壩頂總長3035米，壩高185米，水電站左岸設(shè)14臺，右岸12臺，共裝機26臺，前排容量為70萬千瓦的小輪發(fā)電機組，總裝機容量為1820千瓦時，年發(fā)電量847億千瓦時。通航建筑物位于左岸，永久通航建筑物為雙線五包連續(xù)級船閘及早線一級垂直升船機。

朝辭白帝彩云間，千里江陵一日還。
兩岸猿聲啼不住，輕舟已過萬重山。
—— 唐 李白 下江陵
關(guān)于三峽的資料：
船出了西陵峽，經(jīng)過一段寬谷的航行后就進入了長江三峽的另一座古城巴東。長江三峽的巫峽就從巴東縣的官渡口開始，結(jié)束于四川省巫山縣的大寧河口，全長42km，巫峽以巫山得名。她幽深秀麗，千姿百態(tài)，以俊秀著稱天下。峽谷內(nèi)長年云遮霧繞，細雨蒙蒙，及易形成巫山云雨的奇妙景觀。谷深峽長，奇峰突兀，江流曲折，百轉(zhuǎn)千回，船行其間，宛若進入奇麗的畫廊，充滿詩情畫意，令人嘆為觀止。不少觀光游客游過巫峽之后，感觸頗深地說：“要知中國畫與中國山水的關(guān)系，不到巫峽不明白�！碧瞥娙嗽≡x詩曰：“曾經(jīng)滄海難為水，除卻巫山不是云�！笨梢娢咨皆朴昴耸翘煜略朴曛诹�。
要求學(xué)生模仿課文，敘述三峽工程。
