Transcript

In January 1925, children in a small town in Alaska were getting sick.

The medicine was more than 1,000 kilometres away, and planes could not fly in the cold.

So the dogs ran.

This is the story of Togo.

Welcome to brightlivesenglish.com, where we teach real English using real-life stories.

Serum. A serum is a medicine made from blood that fights a disease.

The serum was more than 1,000 kilometres away.

Relay. A relay is a race or a job where one team takes over from another.

About twenty mushers carried the serum in a relay.

Musher. A musher is a person who drives a team of dogs.

Leonhard Seppala was a champion musher.

Sled. A sled is a vehicle that slides over snow, pulled by dogs.

Togo led the dogs that pulled Seppala's sled.

Blizzard. A blizzard is a storm with strong winds and a lot of snow.

Near Nome, a blizzard turned over Gunnar Kaasen's sled.

Now, one pattern: while plus the past continuous.

We use it for something that was happening when something else happened.

The town was waiting.

The dogs ran.

While the town was waiting, the dogs ran.

Ready? Let's begin.

In January 1925, the only doctor in Nome, Alaska, found diphtheria, a deadly disease that is most dangerous for children.

His old medicine was almost useless.

While the children were getting sicker, he sent messages asking for help.

Ice had closed the port for the winter.

The serum was more than 1,000 kilometres away.

The few planes in Alaska had open seats, and it was far too cold to fly.

So the serum went by railway to a town called Nenana.

About twenty mushers carried the serum in a relay.

More than 150 dogs pulled their sleds, night and day.

It was so cold that one musher's hands froze to his sled.

Leonhard Seppala was a champion musher.

His lead dog was Togo, a 12-year-old husky.

As a puppy, Togo was so naughty that Seppala gave him away.

But Togo jumped through a window and ran back home.

Togo led the dogs that pulled Seppala's sled.

They raced about 270 kilometres east from Nome to meet the serum.

But nobody could tell Seppala that the relay was going faster than planned.

Near a village called Shaktoolik, he almost raced past another musher, who shouted, "The serum! I have it here!"

To save time, Seppala chose the short way back, straight across the frozen sea.

The ice was rough, and in places it was starting to break.

It was getting dark, and a strong wind was blowing.

On the ice, Seppala could hardly see.

He had to trust Togo to find the way.

For hours, Togo led the team across the cracking ice.

At last, they reached the shore.

While the team was resting at a roadhouse on the shore, the storm broke up the ice behind them.

The next day, they crossed the hills and gave the serum to the next musher.

In all, Togo ran about 420 kilometres, the longest part of the relay.

The last musher was Gunnar Kaasen.

Near Nome, a blizzard turned over Gunnar Kaasen's sled.

He found the serum in the snow with his bare hands, and his lead dog, Balto, led the team on.

About five and a half days after it left Nenana, the serum reached Nome.

While the town was waiting, the dogs ran.

The serum was frozen, but not one bottle was broken, and by noon it was ready to use.

Balto became famous, and a statue of him went up in New York.

But many people say that Togo did the longest and hardest part.

In 2011, "Time" magazine put him on its list of the most heroic animals.

Let's review. The serum was more than 1,000 kilometres away.

About twenty mushers carried the serum in a relay.

Leonhard Seppala was a champion musher.

Togo led the dogs that pulled Seppala's sled.

Near Nome, a blizzard turned over Gunnar Kaasen's sled.

And remember: while the town was waiting, the dogs ran.

Togo's story teaches us: the real hero is not always the famous one.
