18．　　The oil paper umbrella is a traditional Chinese handicraft (手工艺品). It has a history of over 1,000 years in China. In early Tang Dynasty, it was introduced to Japan and Korea, so it was called the "Tang Umbrella". Later oil paper umbrellas were spread to other Asian countries, such as Vietnam, Thailand and Laos, and each had its own style. However, as steel-ribbed (钢骨的) umbrellas appeared in the last century, the hand-made oil paper umbrellas became less used in daily life. They were turned into decorative artifacts (装饰性工艺品).
　　Yuhang in Hangzhou is known for making oil paper umbrellas for more than 230 years. They are mainly made of skin paper (皮纸), bamboo, a coating of Tung oil (桐油). They need to take more than 70 steps to make, including making bamboo ribs, pasting papers (糊纸) and painting patterns (图案). It takes at least a week to make per umbrella. In 2008, these umbrellas were added to Intangible Cultural Heritage List (非物质文化遗产名录) of China.
　　A young man called Liu Weixue learned the traditional art of making Yuhang oil paper umbrellas from his grandfather. "I want to bring the art to life." Liu said. He improved the umbrellas to win the hearts of young people. As the traditional paper was easy to break, he started to use a kind of thicker paper. In a test, his umbrellas were opened and closed for 1,000 times without breaking. He used a kind of lighter bamboo to make the umbrellas weigh less.
　　Now Liu hopes the art can be passed on. He goes to local schools to teach students. He also goes to events in different places to promote (推广) the art.

19．　　Recently, China has announced the list of the first five national parks.
　　Each of them is divided into two parts — the core (核心) protection area and the general control area. In the core protection area, only research and surveillance (监视) in science are allowed. And the general control area is open to the public, allowing travel activities such as camping and hiking. In the future, national parks are expected to be natural classrooms. People can learn about different kinds of animals and plants through eco-friendly (环保的) travel activities.
　　The national parks can also be helpful to local people. The building of these national parks provides many jobs for local people. People living in or around the parks can work as park rangers (护林员) and guides. They can also sell some eco-friendly things with local color. So their yearly incomes (收入) will grow a lot.
　　Then let's take a look at the five national parks.

20．　　One day, Helen shouts, "Roger, come and look at the egg! It's cracking (裂开)." Slowly a long beak (喙) appears. They are unsure what it is.
　　Dad checks on the computer, "Hey, look! It's a pterodactyl (翼手龙)." "A pterodactyl?" shout the children. "Yes, it's a type of dinosaur. Pterodactyls can fly," says Dad.
　　Then Helen names it Dacty.
　　A month later, he grows up. But there is something wrong with his wings. "My room is too small and Dacty keeps banging (碰撞) his wings on the walls. I feel sorry for him," says Helen. Finally, they take Dacty to a vet (兽医).
　　Two weeks later, Dacty's wings are better. However, he isn't willing to fly. They phone Aunt Elizabeth. Soon she arrives. "My office is very big. It's perfect for Dacty during the day. And at night, when the museum is empty, Dacty can fly around happily." Then she takes them to the museum. On arriving, they take Dacty out of the basket. He stretches (伸展) his wings, flies high up and lands on a stone statue.
　　"Look, he likes here," shouts Helen. "Can he see in the dark?" asks Roger. "Yes, they see clearly in the dark, just like owls (猫头鹰)," says Aunt Elizabeth.
　　Six months passes and Dacty is very big now. One night, Dacty sees lights moving inside the museum. Two men — Bert and Eric come in with torches (手电筒). They are wearing masks and trying to open a case (箱子). Inside it is a mummy (木乃 伊). Suddenly Eric looks up and sees Dacty. He is very scared. "Look, Bert, there is a huge bird up there." Bert looks up. Dacty doesn't move, "Eric, don't be silly. It's only a statue," says Bert. "Come on. I will open the case. You look for the gold medallions (大奖章)." At the moment, Dacty flies down and catches Eric. The thief is very scared and he can't say anything. Dacty flies up and lifts him on top of a statue. He's stuck. At once, Dacty flies down again and catches Bert, too. Both of them are stuck there.
　　The next morning, when Aunt Elizabeth comes in, she sees the broken mummy case and the two men. They are shouting loudly.
　　Dacty flies down to her. "Here you are, Dacty," she says and pets (爱抚) his head. "Thank you, you did a great job." Then she phones the police.
　　The mayor (市长) shakes Dacty's wing and puts a big shiny medal over his head. "Congratulations, you did a great job." Then he turns to Aunt Elizabeth, "It's great to have a big bird as a guard!"
　　"Dacty is a pterodactyl!" Roger says.
　　"Dacty is a hero now," says Aunt Elizabeth.
　　"A pterodactyl?" shouts another man. "Wow! They love warm weather and jungles (丛林). I work in the Botanical Gardens (植物园). We have a wonderful palm (棕榈) house, big and warm, just like a jungle. He will love there. You can come to visit it anytime."
　　So now Dacty is living in the Botanical Gardens. Roger and Helen visit him every day.
