1、Unit 6Period 1 Starting out&Understanding ideas课 堂 学 习Look at the pictures and answer the questions.1 What does each picture show?2 What difficulties would people have surviving in these situations?1Starting out 1 What does each picture show?2 What difficulties would people have surviving in these s

2、ituations?The first picture shows that an earthquake has happened.The road is cut off.The second picture tells us that a disease has broken out and is probably spreading.In the third picture,we can see a ship sinking.The fourth picture shows us a dense jungle.In the fifth picture,we can see an astro

3、naut in space.The sixth picture shows us a severe drought.Below are the difficulties people would have surviving in each situation.1)People would find it difficult to leave the area to find safety,or to receive supplies such as food,water,medicines and fuel.Power and communications may have been cut

4、 off by the earthquake.There is a risk of further quakes via an aftershock.2)People may face difficulties such as quarantine,shortage of hospital services and panic-buying of essential medicines,food and other supplies.There may be misinformation and panic.3)People who are unable to escape the ship

5、on a lifeboat face the immediate dangers of drowning or of dying from exposure.Those who do escape on a lifeboat need to ration their food and water,and hope for rescue as soon as possible.4)People would find it difficult to travel and navigate.It would also be difficult to find food and water.Wild

6、animals and venomous insects are also potential problems.5)Space is an extreme environment for human beings.They face danger from extreme temperatures,low pressures and radiation.They must carry everything they need with them,even air.The lack of gravity makes simple actions such as eating,drinking,

7、moving and even sleeping difficult.Anyone who spends too long in a zero-gravity environment risks losing bone and muscle mass.6)Without water,people and livestock face death within a short period of time.In addition to water shortages,drought causes crop failure,so people would face food shortages a

8、s well.This could affect people who do not live in the drought-affected area.Severe food shortages can cause famine,migration,collapse of social order and war.Watch the video and answer the questions.1 Where do the people in the video live?2 What difficulties do they face?How do they overcome those

9、difficulties?3 What part of the life there would be most challenging for you?Why?21 Where do the people in the video live?The people in the video live in Antarctica.2 What difficulties do they face?How do they overcome those difficulties?People living in Antarctic face a lot of difficulties.1)They h

10、ave to endure extreme weather including freezing temperatures,fierce winds and strong blizzards.When they go outside the stations,they wear special clothes for protection.As weather can change from calm to white-out in minutes,people have to take a special survival bag in case they are trapped outsi

11、de overnight.2)One of the most difficult things is the long days and nights.They may cause issues with the scientists body clocks.The darkness also makes outdoor research impossible.3)It is almost impossible to grow fresh produce there because of the extreme conditions,and most food is imported.It i

12、s difficult for scientists to have a varied diet,and they cant get enough fresh fruit and vegetables.4)They have to face psychological problems.To keep the scientists psychologically healthy,research stations offer activities and entertainment including live music and lectures.3 What part of the lif

13、e there would be most challenging for you?Why?1Look at the pictures and answer the questions.Understanding ideas foxleopardbearracoonchacma baboonhedgehog1 Where would you normally expect to find these animals?2 Would you be surprised to see these animals in a city?Why or why not?3 What problems cou

14、ld they encounter in cities?1 Where would you normally expect to find these animals?2 Would you be surprised to see these animals in a city?Why or why not?3 What problems could they encounter in cities?In the wild.Yes.Because they are normally in the wild,and they are sometimes dangerous for humans.

15、Its also difficult for them to find shelters and food in the cities.They may have difficulty finding food,shelter and mates.If people find them,they may be trapped or killed.2Look at the title of the passage and the picture.Think about what the title means.PredictingNow read the passage and check yo

16、ur answer.The Wild Within1 The crime took place in a seaside suburb of Cape Town.Spotting the car with its window left open,the greedy thief didnt hesitate.Within seconds,he had reached inside and run away with a bag of shopping.No matter how many crimes he committed,the police were powerless to arr

17、est him.You see,this was no ordinary criminal:it was a chacma baboon.Once almost unheard of,scenes like this one in Cape Town are now common all over the world.With foxes in London,mountain lions in San Francisco and wild pigs in Hong Kong,it is almost as if our cities are being taken over by wild a

18、nimals.2 _ Most of us would assume that urban development and climate change are responsible for pushing the animals out of their natural habitats.However true this is,we also need to consider that some of these so-called“urban animals”have never moved at all-its we humans who have moved into their

19、territory.Wherever they go,animals find towns and cities in their way.With nowhere else to make their homes,they have no choice but to move in with us.3 _ As our cities become greener,they offer increasingly appealing spaces to animals looking for new habitats.Out of reach from many of their natural

20、 predators,these newcomers often flourish in their new city lives.Today,foxes can be seen all over London-one even being found living on the 72nd floor of the Shard building when it was under construction!Whats more,hungry animals are finding plenty to eat in our gardens and in the leftovers we thro

21、w away.4 _ There is evidence that urban racoons are more intelligent than their wild cousins,as they frequently have to figure out difficult problems such as how to open rubbish bins and other containers which they would not find in the wild.Some animals have even changed their living habits to fit

22、in with their new homes.Although naturally active at night,urban foxes come out in daylight if the reward is good enough.Their city location also means that they are getting a taste for the multicultural cuisine on offer from the garbage,such as hamburgers,lamb kebabs and even garlic bread!5 _ Unabl

23、e to distinguish between blue sky and glass,birds crash into windows at speeds of about 50 kilometres per hour.Recent studies estimate that between 400 million and l billion birds die from window impacts each year in the US alone.Shockingly,these deaths amount to around ten per cent of the total US

24、bird population.Some species are more affected than others.One theory behind this is that these birds have yet to change their migratory routes that take them through cities with high-rise buildings.6 However they adapt to our ways of urban living,its important that we get a better understanding of

25、and even learn to appreciate our wild neighbours.Only then can we look towards harmoniously sharing our urban habitats.Whatever the reasons behind these species entering our cities,one thing is for sure-as its often a means of their survival,they could be with us to stay.Read the passage and find ou

26、t what the title means.The title means the wild animals within the cities.SkimmingChoose the topic sentences for Paragraphs 2-5 and write them on the lines to complete the passage.3Scanninga One thing crucial to the increasing number of“urban animals”is their ability to adapt.b People often wonder a

27、bout the reasons behind this mass urban migration.c For those animals that dont adapt,the city can be a dangerous or even deadly place.d Yet,for its newest and wildest inhabitants,a city can offer many benefits.Para.2b Para.3d Para.4a Para.5cRead the passage quickly and work out its structure and co

33、through cities with high-rise buildings.9 look towards harmoniously sharing our urban habitats Now think about what people can do to achieve a balance between the need for urban development and the protection of wild animals.1 Humans build cities not only to make themselves live,also to let the wild

34、 animals survive.2 When building cities,humans should not occupy the living space of wild animals.3 It is a sign of modern civilization to let wild animals find habitats in cities just like human beings,which can contribute to a good biodiversity and a complete ecology.1 How would you describe the r

35、elationship between people and urban animals in the passage?2 What figure of speech is used in the first paragraph?Why does the author choose to start the passage this way?3 Some environmentalists argue that we should restrict urban development to leave enough natural habitats for wild animals.Do yo

36、u agree with this?Give your reasons.Think&Share1 How would you describe the relationship between people and urban animals in the passage?2 What figure of speech is used in the first paragraph?Why does the author choose to start the passage this way?3 Some environmentalists argue that we should restr

37、ict urban development to leave enough natural habitats for wild animals.Do you agree with this?Give your reasons.In the first paragraph,the author uses personification to describe what urban animals are doing,with the aim of attracting readers attention.Animals have no choice but to live with us.We

38、humans should learn to understand them,appreciate them and live with harmoniously.Yes,I agree with this opinion.With the acceleration of human urbanization,more and more animals habitats have been destroyed or invaded.This has deprived the animals of their homes and food.They have nowhere to go and

39、face threats to their survival.Therefore,human beings should slow down the speed of urbanization.1.Spotting the car with its window left open,the greedy thief didnt hesitate.贪婪的窃贼在发现有辆车的车窗未关后，没有丝毫犹豫。(1)“Spotting.open”为现在分词短语作时间状语；with.left open为 with复合结构作后置定语，修饰the car。(2)spot 注意到，发现 e.g.Ive just sp
