The 18-meter-tall Rubber Duck arrived in Beijing on Friday. It was placed on waters in the International Garden Expo Park, where the Yongding River passes through.
The Rubber Duck exhibition was designed by Dutch artist, Florentijn Hofman. It was part of the activities of Beijing Design Week, which ran from September 26 to October 3 in 2013.
The Rubber Duck stayed in the park until September 23, then moved to the Summer Palace, a famous Beijing tourist spot, where it was on display until October 26.
The duck is made of over 200 pieces of rubber. It was guarded not only by staff, but also by 10 volunteers wearing yellow T-shirts and hats with a rubber duck logo.
Sun Yidong, a volunteer who guided visitors to the duck, said the art brought energy to the traditional Chinese park.
“Seeing the giant Rubber Duck makes me feel like I’m a kid again.” Sun said.
Because of the rain on Friday, there were not too many people coming to see it. The Expo workers said they expected more people to come and visit the duck on weekends.
Zhao Yan said she had been following news about the duck since 2007, when the duck began its journey.
“I even considered going to Hong Kong to see it. It’s great that the duck is in Beijing,” Zhao said.
Before arriving in Beijing, the Rubber Duck traveled to 13 cities in nine countries. “The aim of the Rubber Duck is simply to bring everyone back to their childhood again,” said Zeng Hui, a leader of the Beijing Design Week Organizing Committee Office. “It can be a toy for adults.”

Every second there are, on average, more than four babies being born and fewer than two people dying. As a result, the world population keeps increasing.
The baby will probably be born in the Asia-Pacific region. In this area, the population growth rate is higher than anywhere else in the world.
It is just 12 years since the world’s population reached 6 billion. Official estimates say the number will tip 8 billion in 2025 and 10 billion before the end of the century.
With more and more people in the world, there will be less land and water for each person. The major problem will be feeding the new arrivals. Finding housing and medical care for everyone will also be difficult.
For now, China still has the largest population in the world, with 1.34 billion people. In the past ten years it added 73.9 million, more than the population of France and Thailand.
However, its growth has slowed and it is estimated that the population will stop increasing in 2027. By 2050, according to some experts, China’s population will be smaller than it is today.
This is thanks to the family planning policy that started about 30 years ago. In the 1970s, Chinese women had five to six children each on average. Now the number is around 1.5.

Frogs are animals that can live both in water and on land. There are more than 5,000 kinds of frogs on the earth. The earliest known frogs lived about 190 million years ago and the frogs today still look the same. Here are some fun things that you might not know about frogs. Enjoy!
The Biggest and the Smallest Frogs
Some frogs can be very big. The biggest kind of frog is the Goliath Frog in West Africa. Its body can be nearly 30cm long, about the size of a large cat. The Gold Frog and the Poison Frog are the smallest frogs in the world. They are less than 1cm long. Though the Poison Frog is very small, it is not weak at all. It is dangerous. Any animal that eats it will die very soon.
The Best Jumpers
Frogs are very good at jumping. They developed jumping legs so that they would not be eaten by other large animals. Using their big strong legs, more frogs can jump over 20 times their own length. The Australian Rocket Frog can even jump over 2m, which is 50 times its body length (5.5 cm). That might be the reason why frogs are called the best jumpers on the earth.
The Cryogenic Animal
Some frogs like the Common Wood Frog have a special ability to live in very cold places. When the temperature goes down, they become ice frogs. 2/3of their body water freezes. Their hearts stop, and their breathing stops too. You may think they are dead, but in fact they are not. Maybe we humans can learn the way that the frogs do for medical purpose.
1.The earliest frogs lived about ________ million years ago.
A.20
B.30
C.50
D.190
2.________ can jump over 2m.

FOR people who are interested in space, nothing is more exciting than the idea of living on other planets. That might be why the movie The Martian (《火星救援》) is so popular. It shows an astronaut struggling to live on Mars. But would it actually be possible to live on the Red Planet?
While the idea of living on Mars is great, the reality does not look as good. Mars does not have a friendly atmosphere for humans. There is very little oxygen there. And because of its distance from the sun, it is also very cold. The temperature on Mars can be -62 degrees on average. This is much too cold for humans.
However, scientists say it might be possible to live there even without a good atmosphere. Daytime on Mars is almost the same as Earth’s. It means there’s enough sunlight to grow plants inside safe buildings. However, they would have to grow in soil from Earth. Mars does not have a strong enough atmosphere to stop the radiation coming from space, which makes it dangerous to grow things in the soil.
The radiation is also bad for our health. If we want to live there healthily, we need to build our homes under the ground or within the rocks on the planet. This would protect humans from the radiation and also some heat.
When could we actually live on Mars? NASA is hoping to make some progress within the next 20 years.
1.The film The Martian is mentioned in Paragraph 1 to _____.
A. introduce the topic of living on Mars
B. tell readers something about the film
C. explain the development of the film-making business
D. show people’s knowledge of Mars
2.Which of the following about Mars is NOT true?
A. Its atmosphere is not good for humans.
B. It has very little oxygen.
C. It’s colder than Earth.
D. It’s closer to the sun than Earth is.
3.It’s possible to grow plants on Mars because _____.
A. there is enough sunlight
B. the soil is good on Mars
C. it has a good underground atmosphere
D. its temperature changes very little
4.What does Para. 4 mainly talk about?
A. What problems the radiation causes.
B. How to avoid bad conditions on Mars.
C. How to build homes on Mars.
D. How to protect Mars.
