LOCK: Look, Key! I've got information about Nick Motors. He's on an adventure holiday in the countryside.

KEY: Good! These holidays are more exciting than holidays at the beach.

KEY: Look here. It says you can explore forests, rivers and beaches. Can we go, Lock? Please!

LOCK: OK, Key. But we have to catch Nick Motors!

LOCK: He came here yesterday. He caught a bus in the afternoon and had dinner in the Lakeside Restaurant.

KEY: We can catch him easily, Lock. No problem.

LOCK: Excuse me. Do you know this man?

WAITER: Oh yes! I gave him his breakfast this morning.

KEY: Hmmm, but he's not here now.

MISS RICH: Hello! What are you doing here, Mr Key?

KEY: Hello, Miss Rich. We're at work. We're trying to catch a thief.

LOCK: I've got a message on my phone!

LOCK: I don't understand. It says, 'Look behind you!'

KEY: He's got our bike! I need a holiday.

The world isn't mine,

The world isn't yours.

The world isn't his,

The world isn't hers.

It's ours,

It's ours!

Our world is tired, we're making mistakes,

We need our seas, we need our lakes.

Our world is weak, we can make it strong,

It needs our help. Listen to our song.

We must look after its forests and trees,

We must look after its rivers and seas.

We can make it better, we can make it green,

This is our world, let's keep it clean.

The world isn't mine,

The world isn't yours.

The world isn't his,

The world isn't hers.

It's ours,

It's ours!

6 They lost their map so they couldn’t find the museum.

1 They are talking about Shackleton and Cousteau.

2 His ship was called the Calypso.

3 Alex wrote about Jacques Cousteau.

4 Cousteau explored sea life.

ALEX: Hi Simon. Did you finish your homework yesterday?

SIMON: Yeah, I wrote about Shackleton. Who did you write about?

ALEX: Jacques Cousteau. He was a French explorer. Shackleton's adventures were more difficult than Cousteau's, but I think Cousteau is more famous.

SIMON: Really? What did he do?

ALEX: He sailed in his ship, the 'Calypso', and explored sea life.

SIMON: But Shackleton's life was more exciting. Why was Cousteau famous?

ALEX: Because he helped us to understand our world. He made 120 TV programmes and films and he was one of the first people to tell us to be more careful with the sea.

SIMON: Yeah, that's true. We have to look after our world.

STELLA: Huh, our homework was more boring than theirs.

LENNY: Yes, but ours was easier than theirs so I had time to watch TV after I finished mine.

STELLA: Yeah!

1 My book on explorers is more interesting than yours.

2 Shackleton’s adventures were more difcult than Jacques Cousteau’s.

3 Crossing Antarctica is more difficult than climbing trees.

4 Christopher Columbus is more famous than Jacques Cousteau.

5 Simon writes more carefully than Suzy.

6 Sailing is more exciting than walking.

1 Polar bears live on the ice and swim in the sea.

2 They catch and eat other animals like seals, fish and small whales.

3 The world is hotter than it was before.

4 It’s more difficult for polar bears to fish for food.

5 It’s more difficult for polar bears to look after their babies.

PAUL: Can I ask you some questions about the Green Heroes and your project called 'Help the World'?

LILY: Yes, of course Paul. The Green Heroes is a society for young people who want to protect endangered animals.

PAUL: Oh, good. We know now that the earth is hotter than it was before, the weather is changing and animals are endangered. Why is this?

LILY: Well, there are a lot of answers to that question. Today more people drive cars, so the air in big cities is dirtier.

PAUL: So, is it a good idea to walk and ride bikes?

LILY: Yes, it is. We can also use public transport, like buses and trains.

PAUL: Is the problem only in cities?

LILY: No, in the forests people are cutting down trees to get more wood to make tables, chairs and paper, but the world needs trees and forests to clean the air.

PAUL: Oh, what other problems does this give us?

LILY: Well, when people cut down trees in our forests, animals like Siberian tigers lose their habitat.

PAUL: What does that mean?

LILY: Well, when forests get smaller it's more difficult for tigers to live there. It's difficult for them to get food to eat and look after their babies.

PAUL: Oh, dear. So, what can we do to help the world?

LILY: Well, we can do a lot of things. We can use less paper…

A famous explorer, Sir Ernest Shackleton, wanted to cross Antarctica. In 1914 he started the expedition but ice closed round the ship. They took smaller boats and made a camp on the snow. They lost their ship when it went down under the ice and water.

They couldn't move because the weather was terrible. They caught fish and drank water which they got from snow. Later, they had to eat their dogs.

Shackleton and some of his men climbed over mountains of ice, found help and went back for the other men. Everybody came home two years after the start of their expedition. They didn't cross Antarctica.
