How do you think these events or such technology might develop in the future 2. What challenges might they bring 3. What opportunities might they bring Step 2 : 问题导学(5')Future development:Challenges:The AI is programmed to do something beneficial, but it may develop a destructive method for achieving its goal.Opportunities it may take:People can use the AI to do most of the daily chores.More and more people can be free to do work of creating new things.Future development:Challenges:Opportunities it may take:More nanobots will be created to help doctors to find out the root of a disease and make operations more accurately.New kinds of virus may appear and even nanobots can’t find out where they come from.The nanobots may bring more people’s life back.Future development:Challenges:Opportunities it may take:Work in factories will be more efficient. More labor force can be freed from working.More and more workers will be out of work.People will learn more about how to create a machine and how to operate it to help work.Future development:Challenges:Opportunities it may take:More animals even human beings will be cloned.Cloning may result in disorder on the earth.More lives will be saved and more diseases can be cured.Future development:Challenges:Opportunities it may takes:Air pollution will be decreasing. There will be glaciers again in the Arctic Ocean.There may be other threats to the Polar bears.People can live in harmony with the Polar bears.3. Listen to a radio interview with Dr Han andVincent Black giving their predictions about thefuture, and then fill in the table below.Name Occupation PredictionDr HanVincent BlackWhile-listeningcomputer scientistComputers will be cleverer than us in the future; people will also be programming computers to think like humans; we'll be programming them to not think in ways that may harm humans; we'll also be creating machines to help people internally.architectThere will be cities floating on water and people could move into housing in cities that float.Listen for predictionsWhen listening for predictions, you should listen for the use of the future tense, in particular the future tense with will or will be doing. Words such as predict, prediction, and forecast, are also used quite often when making predictions.Step 3: 点拨精讲(23')TapescriptsHost: On today's episode of “Future Changes”, we talkwith two experts from different fields, Dr Han andVincent Black, to hear their predictions about thefuture. First, Dr Han, could you please tell ouraudience what you do Dr Han: Certainly. I'm a computer scientist.Host: And could you please tell us your prediction Dr Han: Yes, well, I forecast that computers will becleverer than us in the future. I think thatpeople will also be programming computers tothink like humans.Host: That's very interesting, but aren't you worriedthat such computers would be dangerous Dr Han: Not at all. This is because we'll be programmingthem to not think in ways that may harm humans.In fact, we'll also be creating machines to helppeople internally. For example, I think scientistswill put some small intelligent machines, callednanobots, inside our bodies to increase ourabilities.Host: Wow! That would make each one of ussuperhuman! And Vincent, could you please tellus about your job Vincent Black: Certainly. I'm an architect, I design buildings.Host: And what is your prediction about the buildingsof the future Vincent Black: It's about the cities of the future, actually.I believe that cities floating on water are partof the world's future.Host: Oh, really What might make us want to do that Vincent Black: Yes. With global warming causing polar iceto melt, the sea level rising by many metresis a very realistic prospect. Instead of movingpeople away from the sea, I think that peoplecould move into housing in cities that float.Host: That sounds very innovative. Could youplease give us more details Vincent Black: Sure. Well, I've developed a plan by designinga city that borrows many ideas from the giantwater lily, a flower that floats on water.Moreover...4. Discuss whether you think Dr Han and VincentBlack's predictions are possible.Why or why not Post-listeningSuggested Answers:I agree on Dr Han's idea that computers will be cleverer than us in the future. Actually there are already computers, like AlphaGo, that are smarter than most people.I don't agree on Vincent Black's idea about floating cities, because I doubt that sea levels will rise that much.5. In groups, brainstorm about the future.Discuss these points.future events or problems the world might facefuture technologieshow these things will change the way we livethe challenges and opportunities these things might bringFUTURE6. Imagine that you have a job that makes you an expert in the future. In pairs, interview each other about your jobs and predictions. Use the expressions to help you.Making predictionsI think/believe/predict that in thefuture ...My prediction is that ...By 2030, we will ...In the (distant) future there will ...I can imagine / forecast ...I doubt / don't think that ...One challenge will be.…We will have the opportunity to ...We will be doing …We are going to ...Sample DialogueA: Good afternoon, Ms Zhang. Thank you for agreeing todo this interview.B: I'd love to.A: First, could you please tell our audience what you do B: Certainly. I'm a doctor. I perform transplant surgeryevery week.A: That sounds like a very high-tech job. How do you thinkthe surgery will be operated in the future Do you haveany predictions about that B: Yes, well, I believe that doctors in the future will havemuch better means to help people. I can imagine thatnanobots will be put in patients' body to detect the illness.Sample DialogueAnd in the future, there will be adequate suppl of organsfor patients who need transplant.A: Well, that would be really good news for all of us.Could you please explain how this will be possible B: Well, it will be possible because of special 3D printers.In the future, doctors will be using them in hospitalsregularly to create healthy copies of people's organs.Then they will replace the unhealthy organs with thehealthy copies.Making predictionsI think/believe/predict that in the future…My prediction is that…By 2030, we will…In the (distant) future there will…I can imagine/forecast…I doubt/don’t think that…One challenge will be…We will have the opportunity to…We will be doing…We are going to…Step 4: 课堂小结(1')假设你是李华,最近你班就“人类是否应该开展克隆研究”进行了讨论,请根据讨论结果,写一封信给某英文报社的记者报道此事。写 作 训 练赞成的理由 反对的理由 你的看法1.挽救濒危动物; 2.再造人体器官,用于移植。 1.引起基因不良变异; 2.克隆人导致伦理道德混乱。 注意:1.词数80左右;2.开头和结尾已给出,不计入总词数;3.可以适当增加细节,以使行文连贯。Step 5: 当堂检测(15')参考范文Dear Editor,Recently our class has had a discussion about whether the clone research should be carried out.____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________Some students are for the clone research.They say cloning is helpful in researching into the cures for many diseases as well as useful in saving the endangered animals.Cloning could also offer perfect organs for patients to transplant._____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________Yours,Li HuaHowever,others are against it.Though clone would improve the quality of life,it might bring about some genetic changes,and have some bad physical and psychological effects.What’s more,it might also raise ethical problems.Personally,cloning should be dealt with carefully and monitored closely by government.Because we do not understand enough what effects cloning will have on the world in the future. 展开更多...... 收起↑ 资源列表 B4 Unit2 Listening and Speaking.pptx 第18页听力Listen to a radio interview with Dr Han and Vincent Black....mp3
