Survival
To learn to get the main idea of the passage from the title and the given picture
To learn to understand the main idea of each paragraph by getting the key information
To think how we can live harmoniously with all the living things in cities
Nature is not limited to faraway mountains and oceans, it also exists in urban cities and our daily lives. In this video we will unfold a world of wildlife we were probably not aware of. Let’s bear this in mind: Building a Shared Future for All Life on Earth.
Look at the pictures and answer the questions.
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.
They may have difficulties finding food, shelter and mates. If people find them, they may be trapped or killed.
There are several animals which are known as foxes, but generally when people think of a fox, they mean the iconic red. The red fox is a member of the so-called “true foxes”, a group which also incudes the Arctic fox, the desert-dwelling fennec fox (with its distinctive large ears), and a number of other less well-known species.
Background information
Leopards are found mostly in sub-Saharan Africa, with small ranges remaining in Western and Central Asia, in India, and in South-east and East Asia.
It is well known for its yellowish fur and
distinctive spots, though leopards
with black coats, known as panthers, also occur. It may be found in a large range of wild habitats, but primarily in savanna (热带大草原) and rainforest.
The racoon is a medium-sized
mammal with grey fur and a
very distinctive dark pattern around its eyes, which makes it look like it is
wearing a mask. It also has a ringed tail, and is very good at manipulating (控制) objects with its front paws. Racoons are highly intelligent animals, and some studies indicate that they can remember the solutions to novel tasks for at east three years.
The chacma baboon, also
known as the Cape baboon,
is one of the largest of all
monkeys. It is perhaps the
longest species of monkey and also
one of the heaviest. It is generally dark brown
to grey in colour, with a patch of rough hair
on the nape of its neck. It is primarily found in
southern Africa, including South Africa, Angola, Zambia and Mozambique.
Hedgehogs are small spiny mammals that feed
largely on slugs and insects, though they will
also eat fruit, birds’ eggs and carrion. They
are known for their habit of rolling into a ball
when threatened, using their spines to protect
themselves. Hedgehogs are native to Europe,
Asia and Africa, and are also
found as an invasive (侵入的)
species in New Zealand,
where they were unwisely introduced by European settlers.
The wild within
growing in nature
inside (the human surroundings)
In this picture, we can see a squirrel, birds, butterflies and some racoons. These animals are living in a city which is ruled by human beings.
The title means the wild
animals within the cities.
The Wild Within
Look at the title of the passage and the picture. Think about what the title means.
Now read the passage and check your answer.
Read the passage quickly and get the main idea of the passage.
The passage explains the impact of human urbanization process on wildlife by introducing the phenomenon of wild animals entering the cities, the reasons behind, their living conditions and the problems encountered in the cities and so on.
Para. 1: The phenomenon of more and more wild animals
entering cities.
Para. 2: The reasons why the wild animals are out of their
natural habitats.
Para. 3: Benefits of cities for wild animals.
What is each paragraph mainly about
Para. 4: The wild animals can adapt to cities and
become more intelligent.
Para. 5: The cities can be dangerous for some wild
animals.
Para. 6: We should learn to appreciate wild animals and
harmoniously sharing our urban habitats.
Choose the topic sentences for Paragraphs 2~5 and write them on the lines to complete the passage.
Para. 2: b. People often wonder about the reasons behind
this mass urban migration.
Most of us would assume that urban development and climate change are responsible for ... However truth this is, we also need to consider that ...
Para. 3: d. Yet, for its newest and wildest inhabitants, a city
can offer many benefits.
As our cities become greener, they offer increasingly appealing spaces to animals ... What’s more, hungry animals are finding plenty to eat in our gardens and ...
Para. 4: a. One thing crucial to the increasing number of
“urban animals” is their ability to adapt.
There is evidence that urban racoons are more intelligent than their wild cousins, as ... Some animals have even changed their living habits to fit in ...
Para. 5: c. For those animals that don’t adapt, the city can
be a dangerous or even deadly place.
Unable to distinguish between blue sky and glass, some birds crash into windows ... Some birds have yet to change their migratory routes ...
More and more wild animals are entering cities.

Now think about what people can do to achieve a balance between the need for urban development and the protection of wild animals.
How would you describe the relationship between people and urban animals in the passage
I think people and urban animals are interrelated in the passage. On one hand, the animals entering cities may cause the loss of human property and pose a risk to personal safety. On the other hand, people could also destroy the habitats of animals to some extent and even threaten their lives.
2. What figure of speech is used in the first paragraph Why does the author choose to start the passage this way
In the first paragraph, the author uses personification (拟人) to describe what urban animals are doing, with the aim of attracting readers’ attention.
修辞手法
3. Some environmentalists argue that we should restrict urban development to leave enough natural habitats for wild animals. Do you agree with this Give your reasons.
I agree that we should restrict urban development to leave enough natural habitats for wild animals. As the range of human beings grow, people need more land and resources, which may lead to human habitations overlapping with those of wild animals. Faced with such conflicts, human beings often choose to reduce the habitats of animals or drive them out of their habitats, which eventually, may lead to the extinction of some wild animals.
Give some suggestions that you believe are good for both urban development and wildlife conservation.
