集宁一中教学设计品味人生1、不管鸟的翅膀多么完美，如果不凭借空气，鸟就永远飞不到高空。
想象力是翅膀，客观实际是空气，只有两方面紧密结合，才能取得显着成绩。
2、想停下来深情地沉湎一番，怎奈行驶的船却没有铁锚;想回过头去重温旧梦，怎奈身后早已没有了归途。
因为时间的钟摆一刻也不曾停顿过，所以生命便赋予我们将在汹涌的大潮之中不停地颠簸。
3、真正痛苦的人，却在笑脸的背后，流着别人无法知道的眼泪，生活中我们笑得比谁都开心，可是当所有的人潮散去的时候，我们比谁都落寂。
4、温暖是飘飘洒洒的春雨;温暖是写在脸上的笑影;温暖是义无反顾的响应;温暖是一丝不苟的配合。
5、幸福，是一种人生的感悟，一种个人的体验。
也许，幸福是你风尘仆仆走进家门时亲切的笑脸;也许，幸福是你卧病床上百无聊赖时温馨的问候;也许，幸福是你屡遭挫折心灰意冷时劝慰的话语;也许，幸福是你历经艰辛获得成功时赞赏的掌声。
关键的是，你要有一副热爱生活的心肠，要有一个积极奋进的目标，要有一种矢志不渝的追求。
这样，你才能感受到幸福。
6、母爱是迷惘时苦口婆心的规劝;母爱是远行时一声殷切的叮咛;母爱是孤苦无助时慈祥的微笑。
7、淡淡素笺，浓浓墨韵，典雅的文字，浸染尘世情怀;悠悠岁月，袅袅茶香，别致的杯盏，盛满诗样芳华;云淡风轻，捧茗品文，灵动的音符，吟唱温馨暖语;春花秋月，红尘阡陌，放飞的思绪，漫过四季如歌。
读一段美文，品一盏香茗，听一曲琴音，拾一抹心情。
8、尘缘飞花，人去楼空，梦里花落为谁痛?顾眸流盼，几许痴缠。
把自己揉入了轮回里，忆起，在曾相逢的梦里;别离，在泪眼迷朦的花落间;心碎，在指尖的苍白中;淡落，在亘古的残梦中。
在夜莺凄凉的叹息里，让片片细腻的柔情，哽咽失语在暗夜的诗句里。
9、用不朽的“人”字支撑起来的美好风景，既有“虽体解吾犹未变兮”的执着吟哦，也有“我辈岂是蓬蒿人”的跌宕胸怀;既有“我以我血荐轩辕”的崇高追求，也有“敢教日月换新天”的豪放气魄。
33 我是一只蜜蜂，在祖国的花园里，飞来飞去，不知疲倦地为祖国酿制甘甜的蜂蜜;我是一只紫燕，在祖国的蓝天上，穿越千家万户，向祖国向人民报告春的信息;我是一滴雨点，在祖国的原野上，从天而降，滋润干渴的禾苗;我是一株青松，在祖国的边疆，傲然屹立，显示出庄严的身姿。

Unit 4 Global warming教学目标1) Learn some knowledge about the greenhouse effect and global warming.2) Know the contents of the text well by talking about this topic and reading.3) Discuss the problem of global warming and express your own opinions学情分析There are two meanings of the term "greenhouse effect". There is a "natural" greenhouse effect that keeps the Earth's climate warm and habitable(suitable for people to live in). Without it, scientists estimate that the average temperature on Earth would be colder by about 30 degrees Celsius (54 degrees Fahrenheit), far too cold to sustain(维持) our current ecosystem. In other words，the normal greenhouse effect is a natural process which is to some degree beneficial to us.重点难点Master the main idea of the first five paragraphs by talking about the topic.教学过程活动1 【讲授】Unit 4Teaching procedures:Step I. GreetingsGreet the whole class as usual.Step II. Lead-inLead to the topic by showing an article to the students and let students know about two types of greenhouse effect ("natural" greenhouse effect and “man-made” greenhouse effect) and their exact meanings.Step III. Analyze two graphs to learn the main idea of the first five paragraphs.From the first graph, we can see that during the 20th century the temperature of the earth rose about one degree Fahrenheit. All scientists agree with the view that the increase in the earth’s temperature is due to the burning of fossil fuels like coal, natural gas and oil to produce energy.More such burning means more carbon dioxide added to the atmosphere.We can see clearly that the levels of carbon dioxide have increased greatly over the past decades.Higher levels of carbon dioxide means sharper increase of the temperature. The phenomenon is called global warming.There has been a debate towards global warming over the pastyears. Opinions about it vary from person to person.Step IV. Read the whole passage to review the main idea of the first five paragraphs and know the two different opinions. Dr. FosterCarbon dioxide has caused the global temperature to ________. An increase of five degrees would be a ____________ and could be very ________.Possible results: __________________(海平面上升)___________________(洪灾)___________________(恶劣的风暴)___________________(干旱)__________________(饥荒)__________________(疾病的传播)___________________________(物种的消失)George Hambley:Any warming will be ______ with few bad ______________________. More carbon dioxide is a _________ thing, which makes crops __________ more and will encourage _____________________.Step V. Discuss the statement: We should take immediate action about global warming.Requirement: Write down your reasons and possible measures on your learning sheetStep VI. Presentation.Ask some students to read their reasons and possible reasons loudly to the whole class.Step VII. Assignment.Make up a complete composition in groups. The passage should include your point of view, your reasons and your measures.精美句子1、善思则能“从无字句处读书”。

Learning ability goals 学能目标Help the students learn how to give their ideas about the use of energy.教学重难点Teaching important points 教学重点Enable the students to express agreement and disagreement.Teaching difficult points 教学难点Enable the students to learn how to express agreement and disagreement.教学过程Step ⅠRevisionT: Good morning, everyone.Ss: Good morning, teacher.T: Sit down, please. Before class, I’ll check your homework first. Mary, would you read your homework to us?Check the students’ homework and have a discussion with the students about the mistakes Mary made. Let the students have a clear understanding about the mistakes and then correct them.Step ⅡWarming upT: As we all know, we depen d on energy to do many things in our daily life. Some people even say we could do nothing without energy. Can you tell me what we use energy for?Sa: Energy lights our cities.Sb: Energy heats our buildings.Sc: Energy entertains us. With the help of electricity, people have got a lot of fun from watching TV, playing computers and so on.Sd: There are many other electrical appliances that make our life more convenient and comfortable such as washing machines, microwaves, air conditioners and so on.Se: Today energy also helps people realize many so-called dreams in the past. For example, people can “fly” from one place to another by plane which runs on energy.Sf: It’s true. In fact, not only planes but also cars, ships and trains run on energy.T: Well done. All that you’ve just said is right. So it seems that energy plays a very important role in the modern world. Then where does all the energy come from? Open your books and turn to page 25. Look at the pictures on this page. They may help you find out the answers.After a while.T: Who’d like to tell us your answers?Sg: Wind power.Sh: Coal power.T: Right. Is there any difference between them?Si: Yes. Wind will never run out while coal is a limited source.T: It’s true. As we know, an energy source is renewable when supplies of it never run out while some supplies， such as coal, will definitely run out one day. Energy of this kind is called non-renewable sources. Please think of as many sources as you can and decide which energy sources on your list are renewable and which are non-renewable.If necessary, give some words related to the pictures which might be difficult for the students such as oil refinery, hydroelectric power and so on.The teacher should also collect as much information about different sources of energy as possible and show it to the students in class through a computer. In this way, the students will become more interested in this topic and their knowledge on this aspect will be enlarged.Sample answers:Step Ⅲ Listening and DiscussingT: Fromwhat we’ve just talked about, it is clear that energy does a lot of good to us.But every coin has two sides. Is there any negative effect of using energy?Sa: Yes.People use too much energy which is resulting in an increase in carbon dioxide.That is how the global warming comes about.Sb: Andmeanwhile it pollutes the environment.T: It’strue. Many people have realized the problem. N ext we’ll do some listeningpractice on this topic. Let’s see what other people think of this issue.Thestudents are asked to read the questions quickly to find out the listeningpoints first. Then listen to the tape twice and give the correct answers.T: No wplease turn to page 31. Let’s do listening. Before you listen to the tape,please read fast the statements in Exercise 1 to find out the listening points.Pay much attention to the key points while listening.Play thetape for the first time. Help the students get a general understanding aboutthe dialogue. The students listen and try to finish Exercise 1.
