Survival
外研版（2019）
Look at the pictures and answer the questions.
Starting out
What does each picture show
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 astronaut in space.
The sixth picture shows us a severe drought.
Starting out
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 off by the earthquake. There is a risk of further quakes via an aftershock.
People may face difficulties such as quarantine, shortage of hospital services and panic-buying of essential medicines, food or other supplies. There may be misinformation and panic.
People who are unable to escape the ship 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.
What difficulties would people have surviving in these situations
People would find it difficult to travel and navigate. It would also be difficult to find food and water. Wild animals and venomous insects are also potential problems.
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, moving and even sleeping difficult. Anyone who spends too long in a zero-gravity environment risks losing bone and muscle mass.
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 as 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.

Para. 1
The crime took place in a seaside suburb of Cape Town. Spotting the car with its window left open, the greedy thief didn’t 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 arrest 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 animals.

Para. 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-it’s we humans who have moved into their 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.
reasons for migration
b. People often wonder about the reasons behind this mass urban migration.

_______________________________________________________________
As our cities become greener, they offer increasingly appealing spaces to animals looking for new habitats. Out of reach from many of their natural 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! What’s more, hungry animals are finding plenty to eat in our gardens and in the leftover we throw away.

_______________________________________________________________
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 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!

_______________________________________________________________
Unable to distinguish between blue sky and glass, birds crash into windows at speeds of about 50 kilometers per hour. Recent studies estimate that between 400 million and 1 million birds die from window impacts each year in the US alone. Shockingly, these deaths amount to around ten percent of the total US 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.
dangers for some animals
c. For those animals that don’t adapt, the city can be a dangerous or even deadly place.

Para. 6
However they adapt to our ways of urban living, it’s important that we get a better understanding of 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 it’s often a means of their survival, they could be with us to stay.

We should learn to better understand and_____________our wild neighbours, and look towards ____________________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.
Tips:
1. Come straight to the point.
2. Put the topic sentence at the beginning or end of the paragraph.
