1 . 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.

Their cheery song brightens many a winter's day. But robins are in danger of wearing themselves out by singing too much. Robins are singing all night一as well as during the day, British-based researchers say.
David Dominoni, of Glasgow University, said that light from street lamps, take away signs and homes is affecting the birds' biological clocks, leading to them being wide awake when they should be asleep.
Dr Dominoni, who is putting cameras inside nesting boxes to track sleeping patterns, said lack of sleep could put the birds’ health at risk. His study shows that when robins are exposed to light at night in the lab, it leads to some genes being active at the wrong time of day. And the more birds are exposed to light, the more active they are at night.
He told people at a conference, "There have been a couple of studies suggesting they are increasing their song output at night and during the day they are still singing. Singing is a costly behaviour and it takes energy. So by increasing their song output, there might be some costs of energy."
And it is not just robins that are being kept awake by artificial light. Blackbirds and seagulls are also being more nocturnal. Dr Dominoni said, "In Glasgow where I live, gulls are a serious problem. I have people coming to me saying `You are the bird expert. Can you help us kill these gulls?'.During the breeding(繁殖)season, between April and June, they are very active at night and very noisy and people can't sleep."
Although Dr Dominoni has only studied light pollution, other research concluded that robins living in noisy cities have started to sing at night to make themselves heard over loud noise.
However, some birds thrive(兴旺)in noisy environments. A study from California Polytechnic University found more hummingbirds in areas with heavy industrial machinery. It is thought that they are capitalising on their predators(天敌)fleeing to quieter areas.

3 . Have you ever noticed that the stars sometimes appear brighter in December, January and February? There's a link between cold air and the night lights. "Part of it is that it tends to be drier in the winter," said Diane Tumshek, an astronomer at Carnegie Mellon University in Pittsburgh, Pennsylvania. Even though it's invisible, moisture can change the way light moves through the air. And in the summer, moisture can make stars appear more dull.
Air temperature is also what puts the twinkle twinkle in the little stars. "Even on very clear nights, some of the atmosphere is cooler, and some of the atmosphere is warmer,” said Tumshek, who also works with the Allegheny Observatory. And when the light from a star passes through those bubbles of varying temperatures, "it bends and shifts the light, so that we are seeing stars appear to dance or twinkle,” she said.
For star lovers in the United States, there's another factor that comes into play for bright winter stars, although this is a matter of coincidence. During Earth's journey around the sun, “there are just simply more bright stars visible from the Northern Hemisphere in the winter sky," Tumshek said. If you really want to see a shiny star, just try to find a burning ball of gas called Sirius near the horizon. At 8.6 light-years away, Sirius is relatively close to Earth and the brightest star visible in the night sky. It is also large — nearly twice as big as our sun and 20 times as bright. So this winter, when the world turns cold and it seems like we should be spending more time indoors, consider asking an adult to go exploring outside. With a warm coat and a clear sky, any night can be turned into a treasure hunt. All you have to do is look up.

4 . In the mid-2000s, Waze Mobile co-founder Ehud Shabtai received a cutting-edge (尖端的) gift from girlfriend: a GPS. The expensive gift was supposed to be helpful. But straight out of the box, it was already out of date.
Shabtai, a coding enthusiast, had an immediate reaction to reinvent. Shabtai’s solution? To build an app. With 80 million monthly active users globally and nearly 400,000 superusers who function much like Wikipedia volunteer editors (editing maps rather than words), Waze Mobile caught the eye of Google as a revolutionary approach to navigation (导航).
Acquired by Google in 2013, Waze’s value mainly lies in its high rate of user involvement. Unlike traditional navigation apps that simply show directions, Waze asks its users to report accidents and other road conditions in real time, so other users can avoid the traffic by using an alternative route.
The goal behind Waze’s approach is an ambitious one: not just avoid traffic, but end it altogether. Waze is finding new ways to put its loyal and active user base to use to make that vision a reality, including a plan to make carpooling (拼车) cool.
To be sure, traffic jams are troubling people all over the world. Waze has been quietly ahead of the game for some time. In 2013, when Waze was just a small digital-mapping business with limited resources it had something Google Maps and other competitors didn’t: richer GPS guidance thanks to its stream of live traffic reports from users.
These users were the basis of Shabtai’s plan to solve for his GPS device’s “silent” hardware: he grounded the app in software that could be perpetually updated by users, anywhere and anytime.
Waze Carpool is going straight to the heart of traffic jams, trying to get more drivers off the road and into carpools. The app has already connected tens of thousands of rideseekers with drivers willing to ferry them along a shared route, and that trend could be the answer to a traffic-free future.

| C．He put it away. | D．He used it anyway. |
| A．It has the most users. | B．It can indicate directions. |
| C．It reports road conditions in real time. | D．Most users help edit its words. |
| A．Difficultly. | B．Carefully. |
| C．Greatly. | D．Constantly. |
| A．The rise of carpooling. | B．An advanced navigation app. |
| C．The development of Google. | D．Traffic problems in the world. |
5 . Ants know when an earthquake is about to strike, researchers have discovered. Their behavior changes significantly prior to the quake and they resume normal functioning only a day after it. Gabriele Berberich of the University Duisburg-Essen in Germany presented these findings on Thursday at the European Geosciences Union annual meeting in Vienna according to LiveScience.
Berberich and her colleagues discovered that red wood ants preferred to build their colonies right along active faults in Germany. They counted 15,000 mounds （土堆)）lining the faults. These faults are the places where the earth violently bursts in earthquakes.
Using a special camera that tracked changes in activity. Berberich and her colleagues tracked the ants round the clock for three years, 2016 to 2019. They found that the ants' behavior changed only when the quake was over magnitude （级数）2. There were 10 earthquakes between magnitude 2.0 and 3.2 during this period, and many smaller ones. Humans can also sense quakes of over magnitude 2 only.
According to Berberich, normal ant activity consists of going about collecting food etc,during the day and resting in the night But before an earthquake, the ants didn't go back to their mound in the night and moved around outside it. This strange and abnormal behavior continued till a day after the earthquake, Berberich told a news conference, according to Livescience.
How do ants know an earthquake is coming? Berberich suggested that they could either be picking up changing gas emissions or noting tiny changes in the Earth's magnetic fields （磁场）. "Red wood ants have special cells which can detect changes in carbon dioxide levels. They also have special cells for detecting electromagnetic fields." she said. Berberich and her colleagues are planning to continue the research in areas where there are more and bigger earthquakes

6 . Both of my parents worked fulltime when I was a little girl，so my grandmother would stay at our house during the day. We would watch game shows in the living room. Our favorite was The Price Is Right. We would call out our answers along with the contestants.
When I got older and started going to school，we couldn’t watch our game shows regularly. That was okay with me，though，because the one thing I liked better than watching game shows with my grandmother was helping her bake cakes. Watching her in the kitchen was amazing：she never seemed to need the recipes（食谱）but everything she made tasted delicious.
At first I would just sit in the kitchen and watch，even though I didn’t understand what she was doing. As I got older，she let me help with the easy parts，such as measuring the sugar. The day she let me separate the eggs，I felt like I had found complete pleasure.
At last，my parents decided that I could take care of myself，and my grandmother stopped coming over every day. The love of baking，however，stayed with me. I started baking by myself，and even if the cookies ended up burnt sometimes，more often they turned out pretty well. I tried out new recipes，and whenever I got to a thorny part，I would call my grandmother for advice. Sometimes I would call her just to talk too. I felt like I could talk to her about anything.
My grandmother passed away ten years ago，but I still think of her every day. Last week，I found a recipe book she made for me. It included her recipes for brownies，cookies，and my favorite，lemon pie. As I looked through the pages，I thought I could hear her voice. She was the one who taught me not just about baking，but about life.

7 . Currently, vegetarianism is increasingly popular, but it is still not the best option for many. If you may be contemplating removing meat from your diet but do not want to go completely meat-free,perhaps try going meat-free for just one day a week.
Sharon Palmer, a registered dietitian and author of Plant Powered for Life, discuses how "research consistently shows that plant based diets are linked with a lower risk of obesity, hypertension,heart disease ,type 2 diabetes and cancer.
She says, "Even going meatless one day a week can make a difference, as you increase all of those whole plant-foods beans, wholegrains, nuts, seeds, vegetables,fruits-and decrease more animal foods, in particular red and processed meat. A high intake of these foods has been linked with increased disease risk.”
Deciding to have a more plant-based diet also increases your intake of fiber, vitamins healthy fats and minerals. To help to do this，stocking your fridge with a variety of beans seasonable veggies , wholegrains, herbs, nuts and seeds is Palmer's secret to eating more plant-based meals.
Palmer's other recommendation is“plantifying”"your favorite dishes. "Just make your favorite dishes or meals plant-based,with a few changes. If you love Taco Tuesday, make your tacos veggie by skipping the meat and serving black beans or a vegetarian mushroom with tofu filling. If you love Indian food, skip the chicken masala and have chickpea masala instead. These will be foods you already love and are familiar with.”
Her biggest advice is to pick one day a week to follow through this and mark it on your calendar, "I love the Meatless Monday idea because people often start their best behaviour at the beginning of the week. . .However, there may be a better day of the week for you. So just plan it. " Palmer said.

8 . A little boy almost thought of himself as the most unfortunate child in the world because poliomyelitis (小儿麻痹症) made his leg lame and his teeth uneven. He seldom played with his classmates; and when the teacher asked him to answer questions, he always lowered his head without a word.
One spring, the boy’s father asked for some saplings (树苗) from the neighbor. He told his children to plant a sapling each person. The father said, “Whose seedling grows best, I will buy him or her a favorite gift.” The boy also wanted to get his father’s gift. But seeing his brothers and sisters carrying water to water the trees happily, anyhow, he hit upon an idea: he hoped the tree he planted would die soon. So watering it once or twice, he never attended to it.
A few days later, when the little boy went to see his tree again, he was surprised to find it not only didn’t wilt, but also grew some fresh leaves, and compared with the trees of his brother and sister, his appeared greener and more vital. His father kept his promise, bought the little boy his favorite gift and said to him: from the tree he planted, he would become an outstanding botanist when he grew up.
Since then, the little boy slowly became optimistic. One day, the little boy lay on the bed but couldn't sleep. Looking at the bright moonlight outside the window, he suddenly recalled what the biology teacher once said, plants generally grow at night. Why not go to see the tree? When he came to the courtyard on tiptoe, he found his father was splashing something under his tree with a ladle (勺子). He returned to his room, tears running down his face.
Decades passed. The little boy didn’t become a botanist, but he was elected President of the United States. His name was Franklin Roosevelt.

9 . Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately：the air you breathe.
Previous studies have linked high exposure (暴露) to environmental pollution to an increased risk of heart problems，but two analyses now show that poor air quality can lead to heart attack or stroke (中风) within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants (污染物) were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA)considers to be of “moderate” (良好) quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.
The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.

But have you ever notice the smell? Unless it is bad, the answer is likely to be no. But while a shop’s scent may not be outstanding compared with sights and sounds, it is certainly there. And it is providing to be an increasing powerful tool in encouraging people to purchase.
A brand store has become famous for its distinctive scent which floats through the fairly dark hall and out to the entrance, via scent machines. A smell may be attractive but it may not just be used for freshening air. One sports goods company once reported that when it first introduced scent into its stores, customers’ intension to purchase increased by 80 percent.
When it comes to the best shopping streets in Pairs, scent is just as important to a brand’s success as the quality of its window displays and goods on sales. That is mainly because shopping is a very different experience to what it used to be.
Some years ago, the focus for brand name shopping was on a few people with sales assistants’ disproving attitude and don’t-touch-what-you-can’t-afford displays. Now the rise of electronic commerce (e-commerce) has opened up famous brands to a wider audience. But while e-shops can use sights and sounds, only bricks-and-mortar stores (实体店) can offer a full experience from the minute customers step through the door to the moment they leave. Another brand store seeks to be much more than a shop, but rather a destination. And scent is just one way to achieve this.
Now a famous store uses complex man-made smell to make sure that the soft scent of baby powder floats through the kid department, and coconut (椰子) scent in the swimsuit section. A department store has even opened a new lab, inviting customers on a journey into the store’s windows to smell books, pots and drawers, in search of their perfect scent.
1. According to the passage, what is an increasingly powerful tool in the success of some brand store?
| A．Friendly assistant. | B．Unique scents. |
| C．Soft background music. | D．Attractive window display. |
| A．show the advantages of brick-and-mortar stores |
| B．urge shop assistants to change their attitude |

| A．a platform that exhibits goods |
| B．a spot where travelers like to stay |
| C．a place where customers love to go |
| D．a target that a store expects to meet |
| A．compare and evaluate | B．examine and assess |
| C．argue and discuss | D．inform and explain |
