Lesson 1: Conversation

The river's so beautiful. I love it.	play_circle pause_circle
Me, too! They're starting boat trips next month.	play_circle pause_circle
It's a pity there aren't any boats for our photos.	play_circle pause_circle
Never mind. I'll take a photo of the bridge... Oh, no!	play_circle pause_circle
What's the matter?	play_circle pause_circle
It's the camera. There's something wrong with it.	play_circle pause_circle
You're joking!	play_circle pause_circle
No, honestly. it's not working.	play_circle pause_circle
Well, we'll have to find another camera and come back tomorrow.	play_circle pause_circle
No, we can't. Laura and I are going to London tomorrow.	play_circle pause_circle
What about the day after tomorrow?	play_circle pause_circle
That's no good for me. My cousin's coming over. I'm meeting her in the morning and she's staying all day.	play_circle pause_circle
This is ridiculous! We've got to take these photos!	play_circle pause_circle
Give me the camera ... Oops!	play_circle pause_circle
Well, now it is broken. You're so clumsy.	play_circle pause_circle
It wasn't my fault!	play_circle pause_circle
Wait a minute! It's working!	play_circle pause_circle
Thank goodness for that! Now let's take these photos of the river…	play_circle pause_circle

Lesson 2: Conversation

So, what are you doing at the weekend, Ross?	play_circle pause_circle
Well, on Saturday morning I'm playing in a basketball match.	play_circle pause_circle
Really? What team are you in?	play_circle pause_circle
Oh, it's just my school team. We're not very good.	play_circle pause_circle
Oh dear! Well, good luck anyway. Are you doing anything else?	play_circle pause_circle
I'm going to the sports center with some friends on Sunday.	play_circle pause_circle

Really? Oh, me too. How about you? What are you doing?	play_circle pause_circle
Well, on Saturday I'm going to London.	play_circle pause_circle
Wow! Lucky you!	play_circle pause_circle
I know. I can't wait. Mom's taking Jack and me. We're going by train.	play_circle pause_circle
What are you doing in London?	play_circle pause_circle
In the morning we're looking at some of the sites. Then we're having lunch at a restaurant. And in the afternoon, we're seeing a film.	play_circle pause_circle
Aren't you going shopping?	play_circle pause_circle
No. We won't have time.	play_circle pause_circle

Well, have a nice weekend.	play_circle pause_circle
Thanks. You too.	play_circle pause_circle

Lesson Heading

Endangered animals in the north	play_circle pause_circle
The polar bear	play_circle pause_circle
The future for polar bears is uncertain. The climate is changing.	play_circle pause_circle
Every spring, the Arctic ice melts earlier and every summer there is less ice.	play_circle pause_circle
The habitat of the polar bears may disappear.	play_circle pause_circle
Nobody knows if they will survive.	play_circle pause_circle
Habitat	play_circle pause_circle
Polar bears live all around the Arctic, in northern Canada, Alaska, Greenland, Norway and Russia.	play_circle pause_circle
In winter, ice covers the Arctic Ocean.	play_circle pause_circle
The sea water round the land freezes, too.	play_circle pause_circle
Polar bears hunt for food on the sea ice.	play_circle pause_circle
In summer, when the sea ice melts, they live on the land but there is little food for them.	play_circle pause_circle
They wait for the autumn when the sea freezes and they can go hunting again.	play_circle pause_circle
Appearance	play_circle pause_circle
Polar bears are the largest kind of bear.	play_circle pause_circle
The male is about 2.5m tall and weighs around 500kg.	play_circle pause_circle
The female is smaller, about 2m tall and weighs about 250kg.	play_circle pause_circle
Their thick, white fur insulates them from the cold.	play_circle pause_circle
Their feet are large and furry. They can walk across the snow easily.	play_circle pause_circle
They can swim well, too, because their feet are partly webbed.	play_circle pause_circle
Diet	play_circle pause_circle
Polar bears hunt the seals that live under the ice in the Arctic Ocean.	play_circle pause_circle
Seals make holes in the ice and they come up to breathe.	play_circle pause_circle
The polar bear waits patiently by the hole.	play_circle pause_circle
When the seal comes up, the polar bear tries to seize it in its powerful jaws.	play_circle pause_circle
Reproduction	play_circle pause_circle
In the winter, female bears make dens under the deep snowdrifts.	play_circle pause_circle
Here the cubs are born.	play_circle pause_circle
The mother bear keeps them warm and fed for several months without ever leaving them.	play_circle pause_circle
When they are bigger, they go outside.	play_circle pause_circle
The mother bear teaches them to hunt on the ice floes.	play_circle pause_circle
Threats	play_circle pause_circle
Loss of sea ice because of climate change is the main threat to polar bears, but pollution from industry and oil spills also threaten them.	play_circle pause_circle
In Russia, a new Arctic Park has been created.	play_circle pause_circle
Here, polar bears will live in safety, protected from harmful industrial activity.	play_circle pause_circle
Look at Nature	play_circle pause_circle
Animals in danger	play_circle pause_circle
This month, we're taking a look at smallest sea mammal in the world.	play_circle pause_circle
The sea otter	play_circle pause_circle
Sea otters live in the North Pacific Ocean.	play_circle pause_circle
There used to be hundreds of thousands of sea otters but almost all of them were hunted and killed for their fur.	play_circle pause_circle
The sea otter was nearly extinct and only 1,000-2,000 were left.	play_circle pause_circle
A hundred years ago, hunting sea otters was banned.	play_circle pause_circle
Now there are more than 100,000.	play_circle pause_circle
Read these facts about the sea otter.	play_circle pause_circle
Sea otters live near rocky coasts of the North Pacific and stay about 1km from the shore.	play_circle pause_circle
They do not have dens on land and they can spend their entire lives in the water.	play_circle pause_circle
They sleep on the sea and eat there, too.	play_circle pause_circle
The sea otter has a thicker fur than any other animal. The outer fur waterproof.	play_circle pause_circle
The soft fur underneath stays dry and protects the Otter from the cold water.	play_circle pause_circle
Otters are between 1m and 1.5m long and weigh from 20kg to 40kg.	play_circle pause_circle
The females are smaller than the males.	play_circle pause_circle
The otter's back feet are fully webbed and they can swim well underwater.	play_circle pause_circle
Sea otters dive to find food.	play_circle pause_circle
They have long whiskers that help them to find their prey in the dark water.	play_circle pause_circle
They can lift boulders on the sea floor and search for sea creatures underneath them.	play_circle pause_circle
They eat snails, crabs and shellfish.	play_circle pause_circle
They use stones as small tools.	play_circle pause_circle
They hit the shellfish with a stone to get them off the rocks.	play_circle pause_circle
Sea otters often sleep at the sea in large groups of 10-100.	play_circle pause_circle
They float on their backs and hold each other's paws to make a 'raft' and keep the group together.	play_circle pause_circle
Otter pups are born at sea.	play_circle pause_circle
The mother floats on her back with her newborn pup on her chest.	play_circle pause_circle
A young pup's fur has so much air in it that it bobs safely on the surface like a plastic ball and is safe from drowning.	play_circle pause_circle
The biggest threat to sea otters is oil spills.	play_circle pause_circle
If a sea otter is covered in oil, its fur cannot keep it warm and it dies of cold.	play_circle pause_circle
Thousands died in 1989 when an oil tanker spilled 40 million litres of oil into the sea.	play_circle pause_circle
Look at Nature - News just received!	play_circle pause_circle
Next year, more oil fields are opening in the North Pacific region.	play_circle pause_circle
More ships will carry oil across the sea, so there is a greater chance that another accident will happen.	play_circle pause_circle
The future of the sea otter is not guaranteed.	play_circle pause_circle
