Tapescript
A: Hello everyone, and welcome to our first meeting fo the Wildlife Club! First let me tell you why we wanted to start this club. A lot of us were trying to think of ways to help endangered animals, and we realised that we could have a group to meet and to get ideas. There are enough of us here to start, but maybe many more students want to do something useful, too.
So we need to encourage them to come to our meetings.
B: Why don’t we design a poster to tell
them about the club, and what we hope
to do here
C: Good idea.
A: And maybe we should decide which
kind of animals to help most. We could
ask the zoo to tell us which animals are
in the most danger.
B: We need to educate people about what
happens to animals. Lots of us buy
gifts when we go on holidays and some
of the gifts are made from animals, but
many people don’t realise that.
A: Yes, it’s terrible to think that elephants,
for example, are used to make jewellery.
C: We need to get working on that poster,
now.

Animals in danger
Many animals are in danger around the world. Here are some examples.
The blue whale lives in oceans around the world. It is the largest animal in the world
Around the world
but it eats the smallest animals for food. Many people kill the whales. And not enough clean water is also a problem. There may be only 1,300 blue whales left
The wild Bactrian camel lives in Northwest China and Mongolia. It’s a large camel and the only species in the world with two humps. There are perhaps 950 left in the wild.
Many Asian elephants live in India but you can find them in other countries as well. There are many elephants which work for people. There might be 35,000 Asian elephants left in the wild.
Module task
Task 1.
Work in small groups. Decide which animal you want to write about. You might want to do more research before
you decide.
where it lives
what the problem is
how many there were before and how
many
there are now
what you or the government can do
about it
Write one or two short paragraphs about it. Look at the paragraphs in Unit 2, Activity 2 to give you some ideas.
Task 2.
The Crested Ibis(朱鹮) is one of the animals most in danger. They live at an altitude of 1200-1400 meters in the sparse forests (疏林). They live on small fish, crabs, frogs and insects. Because the situation is becoming very serious, the number of Crested Ibises
becomes very low. In 1994, there are only about 20 Crested Ibises left in the wild. But with the help of people, in 2005 the number is rose to about 300.
Our government is working hard to save Crested Ibises. They have built a nature reserves to protect Crested Ibises in Shanxi Province.
