Teenager Jake Deham was skiing with his family in the USA when he fell over and lost one of his skis. His family didn't know that he had a problem. They kept on skiing. When they got to the foot of the mountain, there was no sign of Jake.

    Jake couldn't find his ski anywhere. In the end, he decided to take off his other ski and walk down the mountain. But he couldn't work out the right way to go.

    It was now getting dark and he was a long way from any place of safety. He knew that he might die that night in the cold temperatures. But Jake kept calm. At home, Jake watched a lot of programs about living in difficult situations. He remembered the advice from these programs and knew that he should build a hole in the snow. He made a hole and pointed it up the hill so the wind couldn't blow into it. Outside his hole, the temperature fell to a dangerous-15℃ that night, but inside it Jake was safe from the cold.

    But he had to get down the mountain. The TV programs always said," If you are lost, you should find someone else's tracks(足迹) through the snow and follow them." "I wanted to live my life." remembers Jake." So I got up and I found some ski tracks and I followed those." He walked and walked and finally he saw lights. Nine hours after he lost his ski, he found a team of worker who came to save him. He was safe!

    His mum was very happy when she heard the news. Amazingly, Jake didn't even have to go to hospital. He got through the terrible experience without any injuries.

    So, the next time someone says that watching TV is a waste of time, think of Jake. Sometimes TV can save your life!

I was born in Pittsburgh, a city in the east of the US. With its over 400 1 , the city is sometimes called the "City of Bridges".

Pittsburgh is a big city with a 2 of about 2.3 million. About fifty years ago, there were many steel factories (钢厂) in the city, so people today still 3 it the "Steel City". Times were 4 after the factories closed, and streets were dirty in the past, but now the streets become very5 with modern theaters, shops, and restaurants on them.

Pittsburgh is surrounded (环绕) by hills where you can 6 great views of the city. Many artists, 7 Linda Barnicott and Andy Warhol, loved the beautiful views very much and made lots of great paintings. You can find them in the museums in the city. My favourite painting is Linda Barnicott's My Hometown.

I 8 from Pittsburgh to another city ten years ago but I often 9 now. I miss the people. They are funny and friendly, and I 10 the mountains to the east of the city. I also miss my favourite park, The Point. I often remember the good days when I played games with my friends there.

Many people like to learn natural history from books. But with the Internet, some people share{#blank#}1{#/blank#} knowledge and stories of nature online. 

Uncle Cool's Animal World is{#blank#}2{#/blank#} by HuangXin，who graduated from Peking University with a master's degree in fine arts. He{#blank#}3{#/blank#} up near Hengshan Mountain in Hunan Province. There are so many animals around him. Out of his love for animals, Huang decided to introduce animals to people online in {#blank#}4{#/blank#} interesting way. In his videos, common animals like sparrows (麻雀)are just like our normal people. They have no "big" dreams but live{#blank#}5{#/blank#}. At the same time, he also helps us to look at the everyday lives of animals we seldom hear about. "We live a busy life, so many of us would not even notice animals around us. I hope my video helps connect people{#blank#}6{#/blank#} the wonderful nature, "said Huang. 

If you want to know more about insects, Facts About Wild Insects is a good{#blank#}7{#/blank#}. Liu Pengyu and his insect-loving friends made it in 2018. They spend months finding and studying{#blank#}8{#/blank#} every year. In the past five years，they have found over 10 new species (种类). In their{#blank#}9{#/blank#} time, they hold activities to introduce insects to students and share videos on the Internet. People step on many insects every day. {#blank#}10{#/blank#}，some of them are as special as pandas, "Liu told a newspaper.  The team hopes to raise people's knowledge of protecting insects. 

Oil paper umbrellas have a history of over 1000 years in China. Yuhang in Hangzhou i s known for making oil paper umbrellas for over 230 years. Umbrellas here take more than 70 steps to make. And it takes at least a week to make one. In 2007, this kind of umbrella was added to Zhejiang Province's Intangible Cultural Heritage List. 

Oil paper umbrellas used to be seen everywhere here. However, as steel-ribbed( 钢 骨的 )umbrellas appeared, the oil paper umbrellas became less used in daily life. Instead, they turned into decorative(装饰性的) artworks. 

To bring the art to life, some umbrella-making masters in Yuhang have improved oil paper umbrellas. As the traditional paper is easy to break, they use a thicker paper. So the umbrellas can be opened and closed 1, 000 times without breaking. And a lighter kind of bamboo is used to make ribs. So, the umbrellas weigh less. This kind of umbrellas has won the hearts of many young people.
