5 . Animals are natural resources that people have wasted all through our history. Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the world forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger.
Why should people care? Because we need animals. And because once they are gone, there will never be any more.
Animals are more than just beautiful and interesting. They are more than just a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems.
For example, when farmers killed large numbers of hawks, the farmers’ stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice.With no hawks to keep down their numbers, the rats and mice multiplied quickly.
Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger.
Quite a few countries have passed laws. These laws forbid the killing of any animals or plants on the danger list. Slowly, the number of some animals in danger is growing.
1. What can we infer from the passage?| A．People have known the importance of animal protection a long time ago. |

7 . South Korea has the highest rate of Internet addiction in the world and it is increasingly the country’s children who are spending every waking moment immersing themselves in fantasy role plays or gaming. In the remote mountains of South Korea, teenage Internet addicts are turning up for a 12-day boot camp.
Kyle Won’s addiction is out of control. He spends 10 hours a day on the Internet. Now Kyle’s smartphone is taken away. The teachers here do what they can to get them socializing again; for many, the only friends they have had are online. “I have relationships on the Internet and a real distance has grown with my real-life friends and I know it’s not good,” Kyle said. The teachers show them other possibilities and bring back dreams and hopes that have been buried by their addictions. “We teach them methods of managing their desire to use the Internet so that they can continue to use it when they go back home,” Shim Yong-chool, a teacher here, said. After just two days Kyle said it was helpful. He’s set a good example to others though he hasn’t reached the goal completely.
South Korean psychiatrists (精神病专家) are urging more action as they are finding evidence that too much screen time is a barrier to the developing minds. Professor Kang Seak Young from Dankook University said the addiction was damaging critical thinking. “It affects the frontal lobes (额叶) which are important to critical analysis,” Professor Kang said. “Reading a book and guessing what happens in the story next show activity in frontal lobes but playing popular computer games for a long time shows no activity.”
South Korea is one of the most wired nations on Earth, but it does have a cost. One in every ten kids is an addict, so the country is now learning how to manage its high-tech future to avoid more serious consequences.

| C．It’s good to learn at another man’s cost. | D．Prevention is better than cure. |
8 . My Biggest Challenge
As a writer on an adventure sports magazine, I’d always fought shy of doing the adventurous stuff myself, preferring instead to observe the experts from a safe distance and relay their experiences to readers in the form of written language. Thus, when I was challenged to take part in a mountain climb in aid of raising money for charity — and to write about it afterwards — I was unwilling, to say the least.
I was lucky enough to have a brilliant climbing coach called Keith, who put me through my paces after my daily work. He gave me knowledge about everything from the importance of building muscle groups to how to avoid tiredness through nutrition. It quickly became apparent that the mechanics of climbing were more complex than I had imagined. There was the equipment and techniques I’d never even heard of, all of which would come in handy on the snow-capped peak I’d be climbing.
Aware of the challenge, Keith made a detailed action plan and I forced myself to stick to it, doing a daily workout at the gym and going on hikes with a heavy pack. I perfected my technique on the climbing wall and even went to climb the mountains to get vital experience. My self-belief increased alongside my muscle power and I became confident about finishing the climb.
All too soon I was on a plane to my destination. On that day, when I looked up at the mountain, I thought of abandoning it. But then I remembered all the hard work I’d done and how disappointed Keith would be if I gave up at the last minute-not to mention letting down the charity and the sense of failure I’d experience myself. With a deep breath I gathered my equipment and headed out into the sunshine to meet the rest of the group.
And as I sit here now, tapping away on my laptop, I’m amazed at the details in which I can recall every second of the climb: the burning muscles, the tiredness, the minor problems along the way. Could I have been better prepared? Possibly. Would I be back for another go? Thankfully not. The feeling of being excited when I stood on top of the world is a never-to-be-repeated experience but one I will enjoy forever nevertheless.

9 . A small bowl bought at a yard sale in Connecticut for just $ 35 has been identified as a rare 15th-century Chinese antique.
The blue-and-white bowl was made by China's royal court during the Ming dynasty. It is now expected to sell for up to $500,000, according to Sotheby's auction(拍卖)house in New York, where the auction will take place next month.
The purchase was made last year near New Haven, Connecticut. “I was just hanging around there aimlessly. But when I saw this bowl, I didn't even bargain over the $35 asking price,” the owner said. Shortly after the purchase, he sent photos of the bowl to auction specialists, who identified it as an item of historical significance.
Upon closer inspection, the artifact was found to have originated from the period of Yongle Emperor, who ruled from 1403 to 1424 - a period noted for its distinctive porcelain (瓷器)techniques. It's now valued between $300,000 and $500,000, with the top estimate nearly 14,300 times the amount it was purchased for.
“I was deeply attracted by the techniques. You can see why this bowl is so highly-valued from the very smooth porcelain body, silky glaze(上釉)and special blue coloring, which were never reproduced in later dynasties,” McAteer, an auction specialist, said.
“The Yongle Emperor improved the porcelain techniques and elevated the importance of porcelain from being an ordinary bowl into a true work of art. This small bowl has both practical and artistic value, ”McAteer said.

10 . The idea of billions of people going through a few masks a week during this pandemic definitely rings alarm bells, but a team of researchers in Melbourne may have the solution.
They’ve discovered that adding millions of discarded face masks to road-paving (铺路) mixtures would actually lower the cost of the road, while preventing billions of them from landfills. Just one kilometer of road would need three million masks, and the polypropylene (聚丙烯) plastic used to make single-use surgical face masks also increased the flexibility and durability of the road.
The new material is a mixture of about 2% torn masks, with recycled concrete aggregate (RCA)—a material obtained from waste concrete and other minerals from destroyed buildings. This recycled material was found in the study to be ideal for two of the four layers generally required to create roadways. Paving a kilometer of two-way road with the RCA and three million face masks would result in a change of 93 tons of waste from landfills.
The final product then is more resistant to wear than asphalt (沥青), as well as being cheaper too, provided there was a method for collecting masks. The research team did a cost-analysis and found that, at $26 per ton, the RCA was about half the cost of mining raw materials, and as much as a third of the cost of shipping the used masks to a landfill.
The widespread application would be ideal for large infrastructure (基础设施) projects. For example, Washington has the 11th worst roads in terms of unaddressed repairs in the U.S. If the damaged roads in Washington state were repaired with the RCA/mask mixture, it would reuse nearly 10 billion masks, sparing American landfills hundreds of millions of tons of trash.
It’s said that the team is looking for private industry partners or governments willing to give their plastic mask road an opportunity for a large-scale test.
