Try to guess if you are not sure of the answers.Mars is slightly more than half the size of Earth, with corresponding lower gravity. It’s a dry, rocky planet, with white polar “ice” caps that consist mostly of frozen carbon dioxide. The average temperature on Mars is minus 63 degrees Celsius. A day on Mars is about as long as a day on Earth, plus about 39 minutes. Seasons and years are twice as long as they are on Earth.Since the 1960s, Mars has been the subject of several unmanned exploration missions. However, many such early missions failed.More About MarsIt may be difficult to imagine when people will live on the planet Mars.Predict the main idea according to the title and the pictures.Read the passage and find out why humans might live on Mars.Pre-readingWhile-readingWork out the main idea of each paragraph.Why do we have Plan B for Earth Why is Mars our Plan B What are the challenges of moving to Mars Humans’ exploration related to Mars.Right now, Earth is the only home we have!Paragraph 1Paragraph 2Paragraph 3Paragraph 4Paragraph 5Why do we have Plan B for Earth Paragraph 1Clues from the passageThe greatest ___________in 1960s and 1970snuclear missilesToday the greatest _______to life on Earth_____________________fearriskenvironmental problemsHave you seen the film“The Day After Tomorrow” The Day After Tomorrow is a 2004 American science-fiction disaster film. The film is based on the book The Coming Global Superstorm by Art Bell and Whitley Strieber. The film depicts the catastrophic effects of climate change, with extreme weather events leading to global cooling and a new ice age.Why is Mars our Plan B Paragraph 2___________ close to EarthLess hostile environmentToday ___________ in Martian exploration is greater than ever before.Relativelyour interestFilms such as The Martian enjoy worldwide popularitythe Mars Desert Research StationThe Mars VillageMore governments and organisations are making efforts to educate the public on the Red Planet.Humans’ exploration related to Mars.Paragraph 3Since the 1960s, we have been sending unmanned spacecraft to Mars. Our probes have orbited the planet, sending back valuable data and stunning images.Our robots have explored the Martian surface, testing the soil and searching for resources, water and signs of life.Within the next 25 years, human beings are planning manned missions to Mars.What are the challenges of moving to Mars Paragraph 41234Staying alive will be ___________________, but not impossible.Sending people there will require all the skill, _______ and ___________ of the human race.It would ___________ to reach Mars, travelling through _____________ solar radiation.Even if ______________ do reach Mars safely, they may not be able to return to Earth-ever.courageintelligencetake monthsdangerousthe first settlersa daily challengeBiosphere 2 experimentpossiblea closed spacePeople, animals and plants could _____________.live togetherFunction: own oxygen, food and water, needing nothing from the ________________.outside worldunsuccessfulProvide us with a better understanding.A big step forward.Right now, Earth is the only home we have!Paragraph 5To settle Mars is ___________.Earth is ________________.Human activity have a terrible effect on the biosphere.decades awaygetting warmerUntil we are finally able to live on another planet, we need to take much better care of Earth.How to protect the environment (the Earth) control air pollutionprotect the forest and sea resourcesstop any environmental pollutionWe should...protect water environment, save water resourcesprotect rare animals and plantsreduce the use of motor vehiclecarry on waste recovery useChoose the magazine in which you would most likely find the passage?All About SpaceThe TravellerEnvironmental ConcernsBiology for FunChoose the statements that can be inferred from the passage.Humans have yet not visited Mars.People want to go to Mars on holiday.There are plants growing on Mars.The greatest to life on Earth used to be nuclear missiles.One day, humans will have to go and live on another planet.Our Plan A includes developing renewable energy resources.The Biosphere 2 experiment ended in failure.Find evidence to support your choice.Space agencies of various countries are planning manned missions to Mars that could take place within the next 25 years.1 “Humans have yet not visited Mars” can be inferred from paragraph 3.In the 1960s and 1970s, the greatest fear was that the human race, and possibly all advanced life forms on the planet, could be wiped out by nuclear missiles, just at the push of a button.4 “The greatest risk to life on Earth used to be nuclear missiles” can be inferred from paragraph 1.Scientists are thinking of ways to lower this risk, such as replacing coal and oil with forms of renewable energy.6 “Our Plan A includes developing renewable energy resources” can be inferred from paragraph 1.As early as the 1980s, scientists were building Biosphere 2 in the Arizona desert… Although the two-year experiment was not a success, it did provide us with a better understanding of how humans might be able to live on another planet.7 “The Biosphere 2 experiment ended in failure” can be inferred from paragraph 4.Sometimes, we need to form opinions and draw conclusions that are not directly stated within the given information. For example, from the sentence “While the Moon can be reached within days, it would take months to reach Mars, travelling through dangerous solar radiation”, we can infer that the Moon is less exposed to dangerous radiation than Mars. Headings and pictures can also help us make educated guesses about a text.Post-readingWould you like to be one of the first people to live on Mars Why or why not Which is better, to live on Mars or to solve Earth’s problems Why Can you think of a “Plan C” to save people from the problems on Earth Share it with the class.What theme do the two reading passages in this unit have in common On what aspects does each passage focus The two passages share the theme of protecting our living environments. The first passage focuses on balancing nature and urban development, and the need for harmony between humans and animals. The second passage focuses on our need to protect Earth even if we intend to settle on other places such as Mars in future.TheWildWithinWork in pairs.

We went hiking together on Monday, but became separated due to a heavy rainstorm. Without a compass, I lost direction, and now I am lost in dense jungle.There are no roads at all, so I have to make my own way step by step. I have hurt both my hands quite badly from all the thorns—they are everywhere. To make things worse, I stumbled and sprained my ankle. The pain is killing me! Snakes, monkeys, insects and other animals appear from time to time. Yesterday, I heard the roar of a tiger from far away. I was terrified!I rub sticks together to make a fire every night to keep myself warm and safe. It's really a difficult technique to master, and it takes me several frustrating and worrying attempts every evening. I have to remind myself to be calm and optimistic at every moment.Food also worries me a lot. I've been eating berries to appease my hunger, but I have to be very careful to avoid anything poisonous.Today I have some luck when I find a stream which I can follow. It gives me great hope. I’m confident that I can find my way out! This will have been the most memorable adventure of my life!Presenting ideasRead the passage and answer the questions.The green lizards that lived in the lower branches and trunks of Florida’s trees found themselves in trouble when a tougher species, the brown lizards, were introduced from Cuba. Without enough food to go around, and under pressure from the new arrivals, the green lizards moved higher up the trees, where it is harder to keep a grip on the smoother branches. The green lizards adapted quickly over a relatively short time of 15 years, and now they have bigger pads on their toes and stickier scales to help them stay high in the trees—and well away from their troublesome neighbours!Green lizardsBrown lizardsWhat happened to the green lizards What did they do to cope with it What is the main message of the passage They found themselves in trouble because a tougher species, the brown lizards, was introduced to the place where they lived.
