1 . Plane wings are traditionally strong and thick but a team of researchers led by NASA has created a flexible wing that morphs (变形) as it flies. The new wing is constructed from thousands of units that fit together and function in a similar way to a bird’s wing, says NASA research engineer, Nick Cramer.
“Something like an eagle will lock its joints in while it’s cruising, and then it adjusts its wings to a more suitable shape for its cruising, and then when it wants to do a more aggressive move it’ll unlock its shoulder. That’s a similar response to what we’re doing here,” he said.
The Boeing 787 Dreamliner is constructed from body parts that are so large, so they require outsize molds (模具) to create them. The same applies to the Airbus A380. “The cost of infrastructure (基础设施) that the business needs to invest to build these planes is pretty extraordinary,” said Kenneth Cheung, a NASA research scientist. “So what we’re doing with these projects is trying to reduce all of that, so that you could have the same sort of performance in terms of the materials but be able to manufacture it without setting up all of the infrastructure that’s currently required.”
The new wings are created by putting fiber reinforced polyetherimide into a 3D mold to create each part, which locks together in a process that could eventually be carried out by assembly robots. The new structure can also be easily packed down to allow transport, which also makes it potentially the ideal package for another purpose — to send into space.
While the idea of cheaper, more flexible planes could be appealing to the commercial aviation industry, there are major obstacles to overcome. That demands time, research and money. “If you want to revolutionize the traditional manufacturing process of the aerospace industry, you have to have a really good reason,” Cramer said. “So your performance gain has to be significant enough to justify that. It’s not about whether it’s practicable; it’s about whether it’s financially marketable.”

2 . Those days of sucking (吮吸) up the sides of your rapidly melting (融化) ice cream may soon be over. Researchers have discovered a natural protein that could be added to everyone’s favorite summertime snack to keep it solid for longer, according to a press release from the University of Edinburg in Scotland.
Most people know that, at its most basic, ice cream is made of milk and sugar. But it has other ingredients that give it a solid consistency (黏稠度) — a fat (often oil), air bubbles, and ice crystals. The protein that the researchers discovered, called BsIA, coats all three of them to slow down the rate at which the ice melts and the air escapes. In one study of the protein, published earlier this year, the researchers call BsIA a “raincoat” that can act as a film to keep everything inside it for just a little longer. That same quality prevents big pieces of ice crystals from forming, which can happen if you leave ice cream in the fridge for too long.
BsIA is found in bacteria called Bacillus subtilis that is common in soil, and is already present in some foods. So adding the protein to ice cream wouldn’t bring the same sorts of long-term health concerns as would artificial ingredients (人造添加剂). The researchers note that producers could also add BsIA to ice cream to reduce their fat and sugar content.
Though the researchers have published two papers about BsIA and have tested it in the lab, they are staying quiet on the most recent data they collected, as the Washington Post notes. Importantly, the researchers make no mention about how the new ingredient might affect ice cream’s taste or how much we might enjoy eating it. What’s the good of long-lasting ice cream if you don’t even like it? But it might not be too long before you can try it out for yourself; ice cream with BsIA might be available within three to five years.

3 . Television is a central part of many people’s lives. There are very few places in the world where one cannot find a television set. Some sporting events, such as the Olympic Games or the football World Cup, can attract audiences of many millions. But is television a good or bad influence on young people in the modern world?
Thomas Murray, president of the British Parents Against Television Society, believes that it has not improved young people’s lives. “Television damages family life,” he argues. “At mealtime, families no longer talk to each other. In the evenings, youngsters do not spend good quality time with family members. Instead, they watch television.” Murray says that this lack of communication leads to social problems.
Murray also believes that the content of television programmes provides young people with poor role models. “There is so much violence(暴力) on TV—guns, kung fu fighting, and so on. Young people think that all problems should be solved by aggression.”
It is not just young people’s mental health that worries Murray. “Teenagers don’t get enough exercise because they spend so many hours watching television. They also develop back problems from sitting down for so long, and eye strain from the effort of watching.”
Murray would like to see changes to television habits. “Programmes should be educational. Their contents should be nonviolent and healthy. There should be no programmes after ten o'clock in the evening. Parents should teach their children to enjoy their spare time by playing sports or games. And certainly, the television should be switched off during meal time.
Susan Taylor is a television producer. She believes that television is a good influence on young people. “Television brings the outside world to youngsters. It even brought us pictures from the moon! And look what happens after the Olympic Games or the World Cup matches have been shown on TV. People start to take more exercise. Also, there are a lot of programmes about healthy eating and keeping fit.”
However, Taylor agrees with Murray’s point of view concerning parents. “Of course parents have a role to play in educating their kids. They should turn the TV off during mealtime and they should talk with their children as often as possible.”

4 . This week my client asked me whether I will be working between Christmas and the New Year. I did not know. I had been charging full speed ahead and had not thought about it. I am grateful to my client for motivating me to look up from my computer and take a moment to reflect on 2020 ending and 2021 approaching.
The end of December is a time when people share their reflections on how the last year has gone, and set resolutions in the hope that they will do better in the New Year. However, considering the uncertainty of carrying out resolutions, I invite you to consider the idea of setting intentions now.
Take a moment to reflect on how resolutions work for you.
The Cambridge dictionary defines resolutions as ‘a promise to yourself to do or to not do something’. The first thing that comes to mind when I read this is: what happens when we break the promise to ourselves?
This is typically how it goes for me: Throughout January I am going strong with those resolutions. Then comes mid-February, the novelty (新鲜劲) of the resolutions fades, with the increased demands of life. At last, those resolutions start to take a backseat. This brings a frustration or disappointment at “not succeeding” and a gradual abandonment of the resolutions as though they were never really important. By the next New Year, I would have forgotten what my resolutions were in the first place.
If setting New Year resolutions works for you, then go tor it.
Setting intentions
What if we try setting intentions instead?
Intentions are based on what our values are, i.e., what is important to us in different areas of our life such as our physical health, mental health, career, hobbies and relationships with family, friends, partners and education. They have a broader focus on the present moment and on how we act now. They give us a direction and determination that empower us to achieve goals and meanwhile live a meaningful life in the present.

5 . Great Barrier Reef Choking on Pollutants
Attempts to protect the Great Barrier Reef are failing. A report released Monday by the government in Australia says water quality in the Great Barrier Reef is far below what it should be. It showed that pollution have decreased, but not enough to reach environmental targets.
Sediment (沉淀物) and chemicals can weaken coral, hurting its ability to feed and grow. Coral are live animals that take root in the ocean floor, but they are not plants. Reefs are the hard skeletons (骨架) left at the bottom of the sea by small marine creatures called polyps (珊瑚虫). The polyps then form the larger structure of a reef. Corals also are some of the most diverse ecosystems on the entire planet. They can make a home for invertebrates, crustaceans, fish, and sea snakes.
Steve Miles is Queensland’s environment minister. He says the research shows the Reef needs more protection. “Over that five-year period, we did see some progress towards our targets. Sediment is down 12 percent and pesticides (杀虫剂) loads are down 30 percent. But what is most disturbing is that these results are far from our targets. Progress towards these targets flat-lined in the period 2013-2014. If one of my kids came home with a report card like this, I would be a bit disappointed. There is more bad news here than good news. ” said Steve Miles.
The report also found that fewer than one-third of Queensland’s sugar plantations used techniques to reduce the use of pesticides. Only 28 percent of land managers managed their land properly. They had reduced harmful water run off to protect the health of the Reef. The official target is a 90 percent reduction in pesticide use within three years.
Scientists at the University of Queensland and the Australian Institute of Marine Sciences published their findings Wednesday, July 18 in the journal Science Advances. It found between 1992 and 2010, the recovery rate dropped by an average of 84 percent. But there is hope. The study also found some corals can recover quickly if “acute and chronic stressors” are lessened.
Meanwhile, the Australian government released its updated reef protection plan Friday. It clearly states global temperatures must be stopped from rising in order to save the world’s largest living structure.

6 . These days, it's not unusual to see middle-aged men collecting Star Wars action figures, office workers wearing Hello Kitty accessories, or celebrities like David Beckham playing with Lego bricks. It's becoming more and more common to see adults taking an interest in toys, comic books and the activities that are traditionally associated with children. This phenomenon has given rise to a new word: kidult.
What lies behind the phenomenon? One is about adults' nostalgia （怀旧之情）for the carefree days of childhood, and this is especially true with today's fast-paced, stressful lifestyles. Another is about a societal change in recent decades where people are starting families later. As a result, they have more time and money to spend on themselves. Some adults could only window-shop for their dream toys when they were kids, but now they can afford that radio controlled car or high-priced doll they have always wanted.
Businesses have been quick to exploit the kidult trend, and the number of toy stores that target adults has risen. Companies are repackaging products from past decades and also bringing out new ones for adults. Lego, for example, has brought out an architectural series featuring landmarks from around the world.
Society traditionally disapproves of adults who refuse to put aside childhood interests, viewing the refusal as a sign of social immaturity and irresponsibility. Those who agree with this view sometimes claim that kidults are suffering from the pop-psychology concept known as Peter Pan Syndrome, an anomaly （异常）that people remain emotionally at the level of teenagers. On a grander scale, these kidult opponents （对手）argue that such delayed adulthood causes couples to marry later and have fewer children. This in turn can lead to shrinking national economies, for there needs to be a generational replenishment （补充）
of the workforce.
From the standpoint of kidults, though, this phenomenon is seen as nothing but harmless fun. Kidults insist that having youthful interests keeps them young, happy and creative, and their refusal to conform to society's acceptable tastes shows independent thinking. Besides, they argue that being part of the social trend of delayed adulthood is not purely a personal choice. The real causes include expensive housing, increased educational requirements for employment and poor work opportunities.
Whether the kidult phenomenon will continue to grow or prove to be a passing trend is anyone's guess. As the debate about it continues, remember that there is nothing wrong with being young at heart.

7 . If I could give today's young people three wishes, they would be: More hugs. More time outside in nature. More belief in their own power to change the world. While most people understand the importance of the first two wishes, the third one leaves some folks wondering why young people's belief in their own power is so essential.
Let's start with the idea that all of us-especially young people-need heroes. We need them to be our guides on the difficult trail(足迹)we call life and to show us just how far we can go. And we need heroes today more than ever. Our modern society is terribly confused about the difference between a celebrity and a hero. And the difference: is vital. A celebrity is all about fame(名望)-temporary, superficial fame, usually for qualities that are easy to see: a pretty face, a great dance move. A hero，by contrast, is about character-qualities under the surface that aren't visible until they take action.
Heroes are all around us. They truly hold our world together, through their unselfish devotion to helping others, teaching children, and protecting the environment. They don't want fame, or glory; they just want to help. In so many ways, these unsung heroes pilot the boat in which all of us sail.
Yet, young people hear a lot more about celebrities than about heroes in the media. The hidden message they get from all this is that their self-worth comes from what they buy-which shoes, which cell phone--not who they are down inside. What gets lost in this? Young people's sense of their own potential for heroic qualities--their own power to make a positive difference in the world. Truth is, there is a potential hero, a future difference maker, in every young person. Each of them, from whatever background, is a positive force who can do something. All it takes for that to be true is belief.
How do we help young people believe in their own power? The best way is simply to share examples, of other young people who have made a difference.
Ryan, age 11, has worked tirelessly to raise money to provide clean drinking water to African villages. When he first heard about the plight(困苦)of African children who died from impure water, Ryan was only six years old. In the next five years, he raised over $500,000-enough to build over 70 water wells.
Barbara, age 17, grew up on a farm in Texas. When she realized that local farmers were pouring their used motor oil into rivers, causing pollution, she organized the creation of a recycling center for crude(未加提炼的)oil. Her project has grown to include 18 recycling centers in Texas.
The list could continue.These are but a few examples of young people who have discovered that they can build on their own energy to do something great.

8 . To grow sugary dates in the sand, Siwa’s farmers must first make the desert suitable for farming. An oasis (绿洲) in Egypt, Siwa has been home to humans for thousands of years. Since ancient times, the oasis has hosted farms producing some of the most valuable dates in Egypt, and sugary dates have appeared on Egyptians, tables.
The desert environment in Siwa is not quite fit for plants to grow. For example, the water there contains much salt. However, with local people’s efforts, the Siwa oasis contains complex agricultural fields, where date trees, crops and other plants grow in harmony. That impressed me a lot during my visit to the oasis. To make a new piece of field, farmers first remove the top soil and replace it with a mixture of sand and waste matter from animals. The first plants are medicinal plants. Then, farmers plant date trees and olive trees. These farming skills are passed down from generation to generation.
To grow date trees is demanding. And it takes 10 years for a new date tree to mature, but once it does, the tree produces generous fruit: around 110 pounds of dates per year. Each farmer picks dates with the skilled hands. They climb the trees using nothing more than a belt. In total, Siwa grows more than 25,000 tons of dates from 280,000 trees per year.
The dates can be eaten fresh, or made dry. Every part of the date tree is significant in Siwa, from leaves made into beds and boxes to wood used to build houses. And then, of course, there’s the fruit itself. The dates can be cooked with goat meat or mixed with eggs for breakfast. They can also be mixed with flour, water, and olive oil, and boiled slowly to make a local dessert.
Local farmers once developed many unique date varieties, which their camels carried to Cairo. But later many of those varieties perished. And today only several major varieties remain and some have become quite rare and been at risk. The 1985 construction of a road in the oasis made the survival of local agricultural tradition even tougher.
1. What can we learn about sugary dates from Paragraph 1?| A．They can adapt to tough environment. |
| B．They have existed for a long time. |
| C．They’re introduced to Egypt from abroad. |
| D．They’re the most valuable fruit in Egypt. |

9 . In 2016, the world’s population cast aside 49 million tons of electronic waste, known as e-waste. It has been calculated that this number will grow to more than 60 million tons by 2021.
What is causing the upsurge（激增）in e-waste? Technology is becoming more and more widespread, covering almost every aspect of our lives. Meanwhile, the lifespan of devices is getting shorter-many products will be thrown away once their batteries die, to be replaced by new devices. Companies intentionally plan the obsolescence（过时）of their goods by updating the design or software and discontinuing support for older models, so that now it is usually cheaper and easier to buy a new product than to repair an old one. Since prices are falling, electronic devices are in demand around the world.
As more people buy electronic equipment，manufacturers（制造商）are beginning to face shortages of the raw materials needed to make their products, so recycling and reusing materials from discarded（扔掉的）products and waste makes economic and environmental sense.
Recycling e-waste is practiced both formally and informally. Proper or formal e-waste recycling usually involves taking apart the electronics, separating and sorting through the materials and cleaning them. Companies must obey health and safety rules to reduce the health and environmental hazards of handling e-waste by using pollution-control technologies. All this makes formal recycling expensive. Informal recycling is typically unlicensed and uncontrolled. At informal recycling workshops, men and women recover valuable materials by burning devices to melt away non-valuable materials. Usually they do not wear protective equipment and lack any awareness that they are handling dangerous materials.
With the amount of e-waste growing around the world, recycling alone will not be enough to solve the problem. In order to reduce e-waste, manufacturers need to design electronics that are safer, and more durable, repairable and recyclable. The best thing you can do is resist buying a new device until you really need it. Try to get your old product repaired if possible and, if it can’t be fixed, resell or recycle it responsibly. Before you recycle your device, put any broken parts in separate containers and close these tightly to prevent chemicals from leaking. Wear latex gloves and a mask if you’ re handling something that’s broken.
1. Which of the following is the reason for e-waste’s increasing sharply?| A．The results of updating devices. |
| B．The methods of recycling e-waste. |
| C．The causes of devices’ price dropping. |
| D．The shortages of protective equipment. |
| A．To increase the variety of electronic products. |
| B．To lower the costs of technology innovation. |
| C．To relieve the lack of raw materials. |
| D．To improve the poor quality of e-devices. |
| A．Influence. | B．Harm. | C．Limits. | D．Costs. |
| A．Their ways of reusing waste are encouraged largely. |
| B．They are blamed for generating all the dangerous chemicals. |
| C．They aim to discover rare materials from waste for new products. |
| D．Their workers are unaware of the danger from dealing with devices. |
| A．Everyone should take action to reduce e-waste. |
| B．Companies should be mainly responsible for reducing e-waste. |
| C．Fixing a device could cause more pollution than buying a new one. |
| D．E-waste could be broken down by burying it underground for a long time. |
10 . Recently, a Scottish grocery store employed a robot. The robot, named Fabio, was part of an experiment conducted by the Heriot-Watt University, which explores the combination of men and machines. Elena Margiotta, co-owner of the Margiotta supermarket chain, says, “We thought a robot was a great addition that could show the customers that we are always wanting to do something new and exciting.”
Fabio’s job was to make customers feel welcome and assist them in locating grocery items if asked. Things seemed to start off well. The almost 4-foot-tall humanoid robot greeted customers, talked intelligently about the weather, and even gave hugs and high-fives. Later, its friendliness appeared to wane when a shopper needed help but received a vague answer. Therefore, store visitors began to seek out human employees for help.
Believing it might be better at a job that required more socializing, the shop assigned Fabio to hand out sausage samples. Unfortunately, things did not go well. While a human employee managed to attract 12 customers to try the food in 15 minutes, the robot attracted just two.
Since Fabio was not trained for any other job, the grocery store management decided to “fire” the robot a week after it had first reported for duty. The director of the Interaction Lab at Heriot-Watt says, “When we had to put it back in the box, one of employees started crying because they had become emotionally attached to it. It was good in a way because we had thought they would feel threatened by it as it was competing for their job. ” As he later discovered, the tears were not out of fondness for Fabio, but it was because the robot freed the human employees from the dull task of responding to customers’ questions.
Although Fabio appears to be different within its family, thousands of other quite similar Pepper humanoid robots employed at various Japanese stores and some stores in America seem to be extremely popular with customers.
