exploring the Red Planet had never been easy,scientists are determined to continue their explorations.extremely attractive 决心的Before You Watch1 Mars is the fourth planet from the Sun and the smallest planet in the solar system.2 It is one of the few planets that we can see with the naked eye.3 Like Earth,Mars has volcanoes,valleys,polar ice caps,seasons,and weather.4 Olympus Mons,the largest volcano on Mars,is about twice as high as Mount Qomolangma.Now Read the statements below and decide whether they are true(T)or false(F).Try to guess if you are not sure of the answers.FTTF太阳系肉眼山谷极地冰川奥林匹斯山珠穆朗玛峰Before You WatchWork out the meanings of the following sentences._ The probe separates from the launch vehicle._ The lander lands on the surface of Mars._ The probe enters the Earth-Mars transfer orbit._ Controllers on Earth guide the probe into the orbit around Mars._ The lander discards the protective shield and the parachute._ The space-to-ground communications link is created._ The orbiter and the lander separate._ The rover transmits data back to Earth and receives orders from Earth._ The rover begins to explore the surface of Mars.1New

day.Stephen Hawking believed humans must move into space to survive.“Once we spread out into space and establish independent colonies,our future should be safe,”he said.Robert Zubrin,a rocket scientist,agrees and thinks starting with Mars makes the most sense.He thinks sending people to Mars will allow us to learn a lot-for example,aobut the ability of humans to live in a very different environment.1.What do scientists think of the idea of people living on Mars?2.Which scientists are mentioned?Why are they mentioned here?Some of the worlds most important scientists think the idea of

move into space to survive”and “starting with the Mars makes the most sense”?Para.1Critical thinkingIn pairs,discuss what Stephen Hawking said in Para.1.Analysis:_.My viewpoint:_.Critical thinkingIn pairs,discuss what Stephen Hawking said in Para.1.Analysis:Some people,such as Stephen Hawking,believe that because of war,pollution,climate change,hunger,or overcrowding,the Earth will at some point no longer be able to support human life.As a result,the human race will become extinct.To such people,the only hope for the future of the human race is colonising space.My viewpoint:I disagree with this,because I think that both the Earth and people are stronger and more resilient(能复原的)than this.We will find solutions to our problems here on Earth before colonising space will become necessary.Read Para.2-3 and fill in the table.Challenges Solutions terraform Mars build factories stay healthy in mind and body keep busyget along and work together Para.2-3factories greenhouse gases(carbon dioxide)plants (air)gases people can breathe higher temperature rainfall Draw a diagram of terraforming 1.Do the experts and agency think the project would be successful?2.What is the authors opinion of living on Mars?One particular organisation based in Europe is planning to send the first humans to Mars before 2030.The organisation believes that its project is giving people worldwide the chance to be part of the first human crew ever to live on Mars for good.However,many experts think the projects cost of US$6 billion is too low for it to be successful.The American space agency NASA believes that sending people to Mars would cost about US$100 billion,although this estimate is based on bringing them back to Earth,too.Regardless,it seems that humans living on Mars may well happen a lot sooner than most people believe.One particular organisation based in Europe is planning to send the first humans to Mars before 2030.The organisation believes that its project is

other planet to live?2.What does“terraforming”mean?3.According to the test done in Hawaii,what might be one of the biggest problems for the first humans living on Mars?What might be the solution?4.What is the writers conclusion about living on Mars?He believed humans must move into space to survive.It means changing the environment on a planet so that it is similar to Earths.Feeling bord.Always keep themselves busy with various activities.Humans living on Mars may well happen a lot sooner than most people believe.Read for language1.Robert Zubrin,a rocket scientist,agrees and thinks starting with Mars makes the most sense.2.As a test,six people lived in a Mars-like environment in Hawaii for a year.3.However,many experts think the projects cost of US$6 billion is too low for it to be successful.=is the most logical and practical=a place similar to Mars=the budget of US$6 billion is not high enough for the plan to work Read for language1.Another big concern for scientists is whether humans can move to Mars and still stay healthy in mind and body.2.The organisation believes that its project is giving people worldwide the chance to be part of the first human crew ever to live on Mars for good.3.So humans on Mars would always need to keep themselves busy with various activities.=keep mentally and physically healthy=forever=be occupied with diverse activities Read for languagecome truespread outestablish independent coloniesmake sensebe similar to average temperaturelead to result instay healthy in mind and bodyget alongfor goodmay well Practice1.这句话讲不通。(make sense)2.糟糕的饮食最终会导致疾病。(lead to)3.保持身心健康就是我们的首要任务。4.他这次走是再也不会回来了。(for good)5.他可能是对的。(may well)This sentence doesnt make sense/makes no sense.Horrible diet will finally/eventually lead to illness.Staying healthy in mind and body is our first priority.He may well be right.He is leaving for good this time.Home on Mars?THANKS
