1 . A painting stamped with more than 4.8 million fingerprints and cost over 80, 000 yuan in paper has set the Guinness World Record for the largest fingerprint painting.
The fingerprint painting, named Descendants of the Dragon, was created by Kuang Xianpeng, a 35-year-old painter from Zhuzhou, Hunan Province. It describes a mix of nine Chinese dragons and six arts in ancient Chinese culture.
With a surface area of 1195. 14 square meters, 51. 526 meters long and 23. 195 meters wide, the whole painting used 685 pieces of xuan paper and took Kuang over two years to complete. It also took 40 volunteers two whole days to lay out the painting for Guinness certification officer to measure.
Kuang said it was a very arduous journey, and he had used up all his spare time to finish the work. “It was very hard to master the amount of strength you put in your fingers, ” he said. “You can’t press too hard or too light. Otherwise, your prints will blur. I have wasted over 300 pieces of paper due to blurred fingerprints. ”
The Guinness certification officer Luo Qiong said this world record wasn’t easy to earn. She said each fingerprint must be clear, the painting must have more than four different colors, and the distance between each fingerprint mustn’t be more than 1 centimeter.
The world record for this category had been broken 15 times since 2014, with the previous one set by an Indian with a work measuring 1, 188 square meters.
Before this painting, Kuang had spent 14 years in drawing a pen-and-ink painting of 247 meters long and 1. 6 meters wide, telling stories of historical myths. He also said he would never stop exploring more creative works.

2 . Every year, companies like GoPro manage to pack more and more functions into smaller and smaller action cameras that are less noticeable to wear. But a team of researchers from the University of Washington have managed to build a live-streaming wireless camera that’s so small that even an insect can wear it. It’s not quite small and light enough to be held to a fly, but at around 250 milligrams, the camera was successfully carried by a beetle.
Although the camera inside a modern smartphone is certainly tiny, it’s too large and heavy for an insect to carry once the batteries are added. Capturing millions of pixels（像素）with every shot requires a lot of image processing, which in turn requires a lot of power. Taking an alternate route, the researchers copied nature’s approach to how flies see the world. Their large compound eyes can not only detect motion across a wide field of view（it’s why they’re so difficult to hit）but also feature a small, high-resolution（分辨率）region that can focus on their targets, which helps reduce the load on their tiny brains.
Given its size and low-power approach, the camera’s streaming abilities are similarly limited, with a Bluetooth connection that maxes out at a distance of roughly 120 meters, requiring a remote operator to be fairly close to the camera at all times. However, battery life is surprisingly decent. The camera can run for up to two hours, but to extend that, the researchers included an accelerometer so that it’s only capturing and broadcasting images whenever the beetle is moving That can increase the camera’s battery life to over six hours.
The researchers acknowledge that their design certainly raises some privacy concerns, given how easy it is for insects to find their way into your home. But the camera could provide entomologists（昆虫学者）with new insights into how insects cross their environment, respond to threats in the wild, and even provide a closer look at their social structures.

3 . Gardening is popular in many parts of the world. This outdoor activity gives us beautiful plants, pleasant smelling flowers and fresh fruits and vegetables. And it also does a lot of good to our health.
Gardening connects people. When you are gardening, you are outdoors. So it is a perfect chance to meet and spend time with your neighbors. Most people love to talk about their hobbies, and gardeners are no different. They usually enjoy showing people what they are growing. And most of them enjoy sharing advice and stories about their gardens almost as much as sharing flowers and vegetables from their gardens.
Gardening is a great activity for children. It gets them outdoors and off computers, televisions and cell phones. Gardening is also a great teacher. It can teach a child about where food comes from and healthy eating. It also helps them to understand that the natural resources (资源) are not inexhaustible and the importance of using them carefully.
Then, when you garden, you must move around. All the different movements needed for gardening, like bending and lifting, work small muscles (肌肉) in the body. And you can easily get good exercise when you are digging holes or pulling grass.
In a study, researches looked at more than 2,800 people over the age of 60. They studied their life habits, activities and health over a 16-year period. They found that gardening could lower the risk of future dementia (痴呆) by 36%. Gardening requires people to do many repeated actions, such as picking off dying flowers. These actions have a calming influence on the brain. The brain is still active but not in the same way when we use computers.
You'll feel wonderful when what you grow in a garden looks, smells, feels and tastes good.

4 . Reducing, reusing, and recycling is a way of life in Sweden. Recycling is required by law and garbage is sorted at home before if goes to a recycling center. Recyclables are sorted into seven categories and recycling stations are within just 300 meters of all residential areas. " Recycling almost everything is a must in Sweden now. It actually feels very uncomfortable when you visit another country and cant find easy ways to recycle, " said Owen Gaffney, an expert at Stockholm Resilience Centre and Future Earth.
But not all of its garbage is recycled. Sweden uses alternatives that include incineratinggarbage to make electricity instead of using fossil fuels（化石燃料）to heat 1.2 million homes. About half of household garbage is sent to one of the 33 waste﹣to﹣heat plants. Sweden is importing garbage from other countries to keep these plants running. Sweden is also a world leader in turning food waste into eco﹣friendly biogas（沼气）. It has made food waste collection compulsory beginning in 2021. There is a food waste biogas plant, which allows biogas to be used to run public buses and to heat apartment buildings.
Sweden now wants to deal with those remaining items that cannot be recycled by using a circular（循环论证的）economy approach. It means that products can be reused and only recycled when absolutely necessary. The Swedish government formed an advisory group to find a way of making this part of its environmental policy.
This will not work effectively unless people are taught to change their behavior. Now the government is reforming its tax code so that people could get cheaper repairs or buy used things. The large Swedish clothing retailer（零售商）H&M operates a recycling program that gives customers discounts when they bring back old clothing.
Sweden is fighting climate change by doing all the right stuff. Waste recycling and the plans to switch to a circular economy will go a long way in reducing its carbon footprint and will help stop global warming.

5 . A farmer had a cow. He took very good care of this cow and one day when it was ill, he was very worried. He telephoned the vet.
“What’s the problem?” The vet asked him when he arrived.
“My cow’s ill,” the farmer said. “I don’t know what’s the matter with her. She’s lying down and won’t eat. She’s making a strange noise.”
The vet looked over the cow. “She’s certainly ill,” he said, “and she needs to take some very strong medicine.”
He took a bottle out of his box, put two pills into his hand and said, “Give her these. The pills should make her better.”
“How should I give them to her?” the farmer asked.
The vet gave him a tube (管子)and said, “Put this tube in her mouth, then put the pills in the tube and blow. That’ ll make it.”
The next day the vet came to the farm again. The farmer was sitting outside his house and looked more worried.
“How’s your cow?” the vet asked.
“No change,” the farmer said, “and I’m feeling very strange myself.”
“Oh?” the vet said, “Why?”
“I did what you said,” the farmer answered. “I put the tube in the cow’s mouth and then put two pills down it.”
“And?” the vet asked.
“The cow blew first,” the farmer said.

6 . About 10 years ago,I sat in my office,struggling to write an annual progress report for my leader. I enjoy writing scientific papers that engage my creativity and further my research. But report writing doesn’t come with any reward apart from the momentary satisfaction of finishing something. Like other routine paperwork,I find it hard to get through. So that day,I offered myself a reward : When I finished the report,I'd give myself 2 hours to examine slides (载玻片)under the microscope — a task I've always loved but never had much time for as a staff member. It ’ s a strategy I call " just for fun"，.
The strategy was born out of challenges I experienced in graduate school. I usually delayed putting together reports for university administrators until threatening letters arrived. I never felt that paperwork was advancing my science, but rather sapping my energy and time for research. One of my committee members recognized and understood my difficulties. Then he told me about his strategy of rewarding himself with a fun project when he completed a task that he didn’t particularly enjoy. He advised me to think about doing something similar. I immediately liked the idea.
Over the course of my career，this strategy helped me complete and move past the parts of my job that I didn’t particularly enjoy. The rewards I gave myself provided a way to relax and reminded me why I love being a scientist.
As for that annual report,I spent an ordinary morning on it but got it done. Then I hurried over to the microscope ， eager to inspect a series of slides that my collaborators (合作者) had sent a couple of weeks earlier. To others， it may have looked like work. But to me,it was just for fun.

7 . Nature has provided us with many kinds of resources. It is like a great magician(魔术师), creating wonders on Earth. One of them is the Amazon rainforest, the world’s largest and home to millions of plants and animals. Nicknamed”the lungs of our planet”, it produces about one-fifth of Earth’s oxygen. However, this wonderful natural wonder is now in danger.
Thousands of fires have broken out in Brazil, endangering much of the rainforest. These flames have lasted several weeks and are believed to be the”most intense”in almost ten years, according to BBC News.
The Amazon has seen a large number of fires in 2019. Between January and August, there were over 74,000 fires – the highest number since 2013, the BBC reported.
Forest fires are common during the dry season, which runs from July to October. They are usually caused by natural events like lightning. However, most of the fires this year are believed to be caused by farmers, who use fire as a traditional part of tropical agriculture(农业) to clean land, reported CNN.
“It’s the best time to burn because the plants are dry. Farmers wait for the dry season and they start burning and clearing the areas so that their cattle can have grass,”wrote CNN meteorologist Haley Brink.
The disaster has raised concern(关注) around the world. The Amazon rainforest is important for preventing climate change, said the BBC, absorbing millions of tons of carbon annually. When trees are cut down or burned, the rainforest’s ability to absorb carbon is reduced.
Brazilian climate expert Carlos Nobre told Reuters he’s worried. If more than 20 percent of the ecosystem is destroyed, the Amazon rainforest could reach a”tipping point (临界点)”, where the thick jungle will turn into a tropical savannah(大草原).
Nobre warned that it is not far off, with between 15 and 17 percent of the rainforest having already been destroyed.
The Brazilian government has sent soldiers to fight the fires. Many people have offered their support and called for recovery efforts. For example, Tim Cook, CEO of Apple, said he wanted to donate money and US Actor Leonardo DiCaprio’s environmental charity, Earth Alliance, created a donation fund to help deal with the disaster.
The public are also encouraged to donate to charities concerned with rainforest protection. “Every little bit helps in a bad situation like this,”commented Gizmodo.

8 . Some years ago, Michel-Andre found himself staring at the body of a dead whale on a beach in the Canary Islands. It was obvious that the animal had been struck violently by a ship——but why? Only later, after surveying the whales which lived in the area and measuring the increase of sound pollution from ships did it become clear that there was a link.
The whales had become desensitised to the noise of approaching boats and were being struck by them, often seriously. “We never thought that this could be something that could kill,” recalls (回忆) Andre, who is the director of the Laboratory of Applied Bioacoustics at the Technical University of Catalonia, Barcelona.
Andre has spent 20 years developing an advanced system to better understand why incidents like this happen. His underwater microphones have exposed a world of deafening sound and animal communication never observed with such clarity(清晰) before.
It was not an easy task. Sound waves don't travel through water in the uniform, predictable way they do through the air. Instead, the temperature, salinity (盐度) and, flow of water have great effects on their path.
What can be done? One solution is to change shipping routes to courses where ships are statistically less likely to meet animals. It’s also possible to slow ships down to 18km/h or less, which is less likely to seriously injure a whale.
As for dealing with the root cause of the problem, the UN’s International Maritime Organisation has already published guidelines on how to quieten ships, but it will be a while before the effects of such changes might be observed.
“The ocean is not our world,” comments Andre. But it is ours to look after. And thanks to his work, we can better understand the effects of subsea sound pollution.
1. What does the underlined word “desensitised” in Paragraph 2 mean?| A．Stubborn. | B．Flexible. | C．Dull. | D．Friendly. |

9 . If you are a fruit grower — or would like to become one — take advantage of Apple Day to see what’s around. It’s called Apple Day but in practice it’s more like Apple Month. The day itself is on October 21, but since it has caught on, events now spread out over most of October around Britain.
Visiting an apple event is a good chance to see, and often taste, a wide variety of apples. To people who are used to the limited choice of apples such as Golden Delicious and Royal Gala in supermarkets, it can be quite an eye opener to see the range of classical apples still in existence, such as Decio which was grown by the Romans. Although it doesn’t taste of anything special, it’s still worth a try, as is the knobbly(多疙瘩的) Cat’s Head which is more of a curiosity than anything else.
There are also varieties developed to suit specific local conditions. One of the very best varieties for eating quality is Orleans Reinette, but you’ll need a warm, sheltered place with perfect soil to grow it, so it’s a pipe dream for most apple lovers who fall for it.
At the events, you can meet expert growers and discuss which ones will best suit your conditions, and because these are family affairs, children are well catered for with apple-themed fun and games.
Apple Days are being held at all sorts of places with an interest in fruit, including stately gardens and commercial orchards(果园). If you want to have a real orchard experience, try visiting the National Fruit Collection at Brogdale, near Faversham in Kent.
1. What can people do at the apple events?| A．Attend experts’ lectures. |

10 . Passenger pigeons (旅鸽) once flew over much of the United States in unbelievable numbers. Written accounts from the 18th and 19th centuries described flocks(群) so large that they darkened the sky for hours.
It was calculated that when its population reached its highest point, there were more than 3 billion passenger pigeons—a number equal to 24 to 40 percent of the total bird population in the United States, making it perhaps the most abundant bird in the world. Even as late as 1870 when their numbers had already become smaller, a flock believed to be 1 mile wide and 320 miles (about 515 kilometers) long was seen near Cincinnati.
Sadly the abundance of passenger pigeons may have been their undoing. Where the birds were most abundant, people believed there was an ever-lasting supply and killed them by the thousands. Commercial hunters attracted them to small clearings with grain, waited until pigeons had settled to feed, then threw large nets over them, taking hundreds at a time. The birds were shipped to large cities and sold in restaurants.
By the closing decades of the 19th century, the hardwood forests where passenger pigeons nested had been damaged by American’s need for wood, which scattered (驱散) the flocks and forced the birds to go farther north, where cold temperatures and storms contributed to their decline. Soon the great flocks were gone, never to be seen again.
In 1897, the state of Michigan passed a law prohibiting the killing of passenger pigeons but by then, no sizable flocks had been seen in the state for 10 years. The last confirmed wild pigeon in the United States was shot by a boy in Pike County, Ohio, in 1900. For a time, a few birds survived under human care. The last of them, known affectionately as Martha, died at the Cincinnati Zoological Garden on September 1, 1914.
