Unit 11 Scientific Achievements 全单元教案

I．教学内容分析

从爱迪生到比尔·盖茨，从电的发现到太阳能的利用，科技的每一步发展都给人类的生活带来了质的飞跃，而这一切的发展都离不开人类坚持不懈的探索，离不开科学家们日日夜夜的奋斗。是大自然的奥秘吸引着他们，是科学的精神支撑着他们，是人类一次次的飞跃激励着他们，为此他们创造着一个又一个历史的奇迹。 本单元的中心话题就是“科学成就”，它围绕着科学理论、科学发现等展开一系列的话题。

Warming up部分通过三个问题，要求学生对于图片旁边列举的科学成就展开讨论。首先判断出对世界改变最大的科学成就，并给出适当的理由；第二个问题是考查学生对于科学成就的了解程度，这样的问题设计有利于学生打开自己的思路，搜索并检查自己的知识面；第三个问题主要是通过比较，让学生了解科学成就对人类发展的重要性和贡献，激发学生投身于科学研究的激情，这样对学生的教育就上升到了思想层面，比较深刻。 Listening的第一部分通过对三个为科学做出过巨大贡献的人的语言描写，让学生填写表格，描述他们的功绩；第二部分主要是培养学生获取重要信息的能力，并就其内容将句子补充完整；第三部分是三个假设，给我们的科学探索带来新的动力和激情。 Speaking组织了一个科学研究项目经费申请的口语训练。从口语训练的重点来说主要是为了训练如何表达一个人的意愿和愿望。其中有五个角色，一个是项目研究经费调配负责入，另外四人分别有意致力于以下工程的研究：艾滋病的治疗、克隆技术的利用、干旱地区种植技术的开发和人造卫星的太空旅行。四人各自陈述观点，最后由一人评判结果。这样的设计给我们的同学创设了真实的语言环境，使学生可以在较为真实的情况下锻炼交流能力。 Pre-reading部分设计了三个问题。第一个问题是探索科学研究的环境；第二个问题是讨论科学成就的重要性：科学成就是如何影响我们的生活和整个社会的；第三个问题是谈论科学家致力于科学研究的目的和意义。

Reading介绍中关村的形成、发展及其重要意义。中关村是中国科研的基地和科技人才的摇篮。第一部分讲述了中关村是中科院和几所著名大学的集中地；第二部分谈论中关村是海外学子实现他们梦想的地方。

Post-reading部分主要是对课文的细节做进一步介绍，共设计了5个选择题。第一部分根据课文回答问题；第二部分设计了一个比较性的题目，要求比较中国的中关村和美国的硅谷，并写出相似和不同的地方。

Language study分两部分。一是巩固文中的词汇，选择词义相近的词汇；二是学习语法知识，构词法分：前缀、后缀、合成和缩写四种，并进行一定的训练。

Integrating skills集阅读和写作于一体。首先是阅读一篇关于各个科技领域发展的文章；其次是设计了一个真实性的任务：某杂志要求你挑选你所认为的最伟大的科技成就，陈述你的理由，并加以解释。

Tips教会学生如何写一篇劝说性的议论文。

The theory is now being challenged．This surprising 26 was published in American magazine Science on January 1 8．It was 27 with the help of a Canadian mapping satellite．The 28 used radar to examine changes in the ice sheet． The ice sheets are 29 very slow rivers，with ice flowing down．“Ice streams，”said Iran Joughin，a scientist at the Jet Propulsion Laboratory in California，USA．By 30 the satellite images，Joughin found that the ice streams had slowed in the last 20 years． 31 ，snow is building up on top of the ice sheet faster than the rivers are taking it away。

In the past，greenhouse gases were 32 to be thinning Antarctic‟s ice sheet．These 33 gases，especially carbon dioxide，are 34 to the atmosphere．But Joughin believes other natural forces are creating changes in 35 “I think in this ease it‟s removed from global warming．”he said，“This ice sheet runs on its own time．”

To make matters even more 36 global warming can cause ice sheets to grow．The 37

they get，the more water goes into the 38 ，and the more snow falls over the polar ice caps．Some experts have 39 suggested that what begins as global warming will start another ice age on earth．The scientists said West Antarctica is the only

Let us suppose it is now about 3000 AD．let‟s make believe it is about one thousand years from now．Of course，things have changed，and life is very different．

Voyages to the moon are being made every year．It is as easy as to take a holiday on the moon today as it was for the people of 1980 to take a holiday in Europe．At a number of science spots on the moon，many hotels have been built，and the hotels are air-conditioned，naturally．So that everyone can enjoy the beautiful scenery on the moon；every room has at least one picture window．Everything imaginable is}J1．provided for entertainment of the young and old．

What are people eating now? People are still eating food．They haven‟t yet started to take on their supply of energy directly as electrical current or as nuclear power．They may some day．But many foods now come in pill form and the food that goes into the pill continues to come mainly from green plants．

Since there are several times as many people in the world today as there were a thousand years ago，most of our planet‟s surface has to be filled．The deserts are irrigated with water．Crops are no longer destroyed by pests．The harvest is always good．

Farming．of course．is very highly developed．Very．few people have to work on the farm．It is possible to run the farm by just pushing a few buttons now and then．People are now largely vegetarians. You see，as the number of people increased，the number of animals decreased．Therefore，the people have to be vegetarians and we are healthier in both our bodies and our minds，and we know the cause and cure of sickness and pain，and it is possible to get rid of diseases．No one has to be ill any more． Such might be our life in 3000 AD．

B

The work of French scientist Lamarck has done his bit for the theory of evolution(进化)．He believed that the environment shaped the development of plant and animal life．He believed that the bodies of plants and animals changed to fit their environment．He thought that a useful physical change would be passed on to the plants or animals‟ offspring(后代)．

For example，Lamarck thought that giraffes developed long necks because they had to stretch to reach the leaves of tall trees for food. The earliest group of giraffes stretched their necks a small amount Their-offspring inherited this long neck．The offspring stretched necks a little bit more．They passed this even longer neck on to their own offspring．Over many generations giraffes develop the long necks that they have today．

Not all of Lamarck‟s theory is accepted today．Most scientists do believe that the environment has an effect on the evolution of life form．But they don‟t agree with the theory that a physical change in a plant‟s or animal‟s is passed on to the offspring．Instead，they believe that a change takes place in the plant‟s or animal‟s cells before a change in the offspring can take place． 46．The main purpose of the passage is to discuss__________________． A．the theory of evolution B．the work of Lamarck

C．the evolution of giraffes D．beliefs held by today‟s scientists 47．According to the passage，Lamarck believed that the development of plant‟s and animal‟s life was shaped by the plant‟s or animal‟s________．

A．cells B．environment C．offspring D．physical change

48．Who makes sure that the environment has an effect on the evolution of life form．7 A．Lamarck． B．Most scientists． C．The author．D．Both A and B． 49．Which of the following is NOT true about the passage? A．All the scientists don‟t accept Lamarck‟s theory today． B．Not all of the scientists accept Lamarck‟s theory today．

C．Most scientists believe that environment can cause a change in the bodies of plants and animals． D．Most scientists don‟t believe that a physical change in a plant‟s or animal‟s body is passed on to the offspring．

50．With which of the following statements about L~arck‟s work would most scientists today agree?

A．None of his theories about evolution make sense．

B．An animal that changes physically will always pass on the changes to its offspring． C．Giraffes are the only animals that have changed through evolution． D．Environment can cause a change in the bodies of plants and animals．

In the middle of winter，when snow is falling in many pans of the United States，scientists have sounded a warning to people who plan to spend many hours in the sun this summer．The warning：

The sun‟s summertime rays are more dangerous than once thought．

A team of scientists from 80 nations recently reported to the United Nations that a layer of ozone in the atmosphere，which protects humans from harmful levels of ultraviolet radiation，will be thinner over the United States this summer．The thinner layer allows more ultraviolet rays from the sun to reach Earth．The extra amount of ultraviolet radiation could cause an increase in the number of cases of skin cancer．

Scientists first became concerned about the ozone layer in the mid-1980s when a hole was discovered in the layer above Antarctica during the winter．The hole was caused by chemicals used in refrigerators and air conditioners．When these chemicals are sent out into the atmosphere，they produce gases that destroy the ozone．

Concern about the protective ozone layer rose more recently when data from satellites and ground stations showed that ozone levels were dropping over areas other than Antarctica．Low ozone levels were recorded in the spring and summer over the United States and over other populated areas in the world．

Although many countries have already begun stopping the use of ozone—destroying chemicals，the new findings are expected to advance the timetable for a total ban of the chemicals．

5 1．The scientists have observed the ozone layer_______________．

A since 1980 B．since last winter C．for more than 20 years D．for about one year 52.The ozone layer in the atmosphere can__________． A．do a lot of good to human beings in many ways

B．protect humans from diseases caused by bad weather C．do a lot of harm to human beings in the summertime. D. protect humans from harmful levels of ultraviolet radiation

53． Scientists first found that there was a hole in the ozone laver__________。 A．above arctic during the winter in the mid-1980s B．above Antarctica during the winter in the mid-1980s C．over somewhere in the north of the equator in 1980s D．over the USA in the summertime in the mid-1980s

．The damage to the ozone layer was caused by__________．

A．the change able weather B．ozone-destroying chemicals C．chemicals from refrigerators D．chemicals from air conditioners 55．Which of the following is NOT true?

A．The use of ozone-destroying chemicals has already been stopped．

B．The ozone levels in the spring and summer over the U．S．A were low． C．More and more people have begun to protect the natural surroundings． D．Many countries have already taken measures to protect ozone layer． (四)写作：
