1 . You’ve heard that plastic is polluting the oceans — between 4.8 and 12.7 million tonnes enter ocean ecosystems every year. But does one plastic straw or cup really make a difference? Artist Benjamin Von Wong wants you to know that it does. He builds massive sculptures out of plastic garbage, forcing viewers to re-examine their relationship to single-use plastic products.
At the beginning of the year, the artist built a piece called “Strawpocalypse,” a pair of 10-foot-tall plastic waves, frozen mid-crash. Made of 168,000 plastic straws collected from several volunteer beach cleanups, the sculpture made its first appearance at the Estella Place shopping center in Ho Chi Minh City, Vietnam.
Just 9% of global plastic waste is recycled. Plastic straws are by no means the biggest source (来源) of plastic pollution, but they’ve recently come under fire because most people don’t need them to drink with and, because of their small size and weight, they cannot be recycled. Every straw that’s part of Von Wong’s artwork likely came from a drink that someone used for only a few minutes. Once the drink is gone, the straw will take centuries to disappear.
In a piece from 2018, Von Wong wanted to illustrate (说明) a specific statistic: Every 60 seconds, a truckload’s worth of plastic enters the ocean. For this work, titled “Truckload of Plastic,” Von Wong and a group of volunteers collected more than 10,000 pieces of plastic, which were then tied together to look like they’d been dumped (倾倒) from a truck all at once.
Von Wong hopes that his work will also help pressure big companies to reduce their plastic footprint.

2 . As data and identity theft becomes more and more common, the market is growing for biometric(生物测量) technologies—like fingerprint scans—to keep others out of private e-spaces. At present, these technologies are still expensive, though.
Researchers from Georgia Tech say that they have come up with a low-cost device(装置) that gets around this problem: a smart keyboard. This smart keyboard precisely measures the cadence(节奏) with which one types and the pressure fingers apply to each key. The keyboard could offer a strong layer of security by analyzing things like the force of a user’s typing and the time between key presses. These patterns are unique to each person. Thus, the keyboard can determine people’s identities, and by extension, whether they should be given access to the computer it’s connected to—regardless of whether someone gets the password right.
It also doesn’t require a new type of technology that people aren’t already familiar with. Everybody uses a keyboard and everybody types differently.
In a study describing the technology, the researchers had 100 volunteers type the word “touch” four times using the smart keyboard. Data collected from the device could be used to recognize different participants based on how they typed, with very low error rates. The researchers say that the keyboard should be pretty straightforward to commercialize and is mostly made of inexpensive, plastic-like parts. The team hopes to make it to market in the near future.

3 . Quantum ( 量子 ) computers have been on my mind a lot lately. A friend has been sending me articles on how quantum computers might help solve some of the biggest challenges we face as humans. I’ve also had exchanges with two quantum-computing experts. One is computer scientist Chris Johnson who I see as someone who helps keep the field honest. The other is physicist Philip Taylor.
For decades, quantum computing has been little more than a laboratory curiosity. Now, big tech companies have invested in quantum computing, as have many smaller ones. According to Business Weekly, quantum machines could help us “cure cancer, and even take steps to turn climate change in the opposite direction.” This is the sort of hype ( 炒作 ) that annoys Johnson. He worries that researchers are making promises they can’t keep. “What’s new,” Johnson wrote, “is that millions of dollars are now potentially available to quantum computing researchers.”
As quantum computing attracts more attention and funding, researchers may mislead investors, journalists, the public and, worst of all, themselves about their work’s potential. If researchers can’t keep their promises, excitement might give way to doubt, disappointment and anger, Johnson warns. Lots of other technologies have gone through stages of excitement. But something about quantum computing makes it especially prone to hype, Johnson suggests, perhaps because “‘quantum’ stands for something cool you shouldn’t be able to understand.” And that brings me back to Taylor, who suggested that I read his book Q for Quantum.
After I read the book, Taylor patiently answered my questions about it. He also answered my questions about PyQuantum, the firm he co-founded in 2016. Taylor shares Johnson’s concerns about hype, but he says those concerns do not apply to PyQuantum.
The company, he says, is closer than any other firm “by a very large margin ( 幅度 )” to building a “useful” quantum computer, one that “solves an impactful problem that we would not have been able to solve otherwise.” He adds, “People will naturally discount my opinions, but I have spent a lot of time quantitatively comparing what we are doing with others.”
Could PyQuantum really be leading all the competition “by a wide margin”, as Taylor claims? I don’t know. I’m certainly not going to advise my friend or anyone else to invest in quantum computers. But I trust Taylor, just as I trust Johnson.
1. Regarding Johnson’s concerns, the author feels ________.| A．sympathetic | B．unconcerned | C．doubtful | D．excited |
| A．His dominance in physics. | B．The competition in the field. |

4 . We live in a town with three beaches. There are two parts less than 10 minutes’ walk from home where neighborhood children gather to play. However, what my children want to do after school is pick up a screen — any screen — and stare at it for hours. They are not alone. Today’s children spend an average of four and a half hours a day looking at screens, split between watching television and using the Internet.
In the past few years, an increasing number of people and organisations have begun coming up with plans to counter this trend. A couple of years ago film-maker David Bond realised that his children, then aged five and three, were attached to screens to the point where he was able to say “chocolate” into his three-year-old son’s ear without getting a response. He realised that something needed to change, and, being a London media type, appointed himself “marketing director from Nature”. He documented his journey as he set about treating nature as a brand to be marketed to young people. The result was Project Wild Thing, a film which charts the birth of the World Network, a group of organisations with the common goal of getting children out into nature.
“Just five more minutes outdoors can make a difference,” David Bond says. “There is a lot of really interesting evidence which seems to be suggesting that if children are inspired up to the age of seven, then being outdoors will be on habit for life.” His own children have got into the habit of playing outside now: “We just send them out into the garden and tell them not to come back in for a while.”
Summer is upon us. There is an amazing world out there, and it needs our children as much as they need it. Let us get them out and let them play.

6 . We’ve all been there: in a lift, in line at the bank or on an airplane, surrounded by people who are, like us, deeply focused on their smartphones or, worse, struggling with the uncomfortable silence.
What’s the problem? It’s possible that we all have compromised conversational intelligence. It’s more likely that none of us start a conversation because it’s awkward and challenging, or we think it’s annoying and unnecessary. But the next time you find yourself among strangers, consider that small talk is worth the trouble. Experts say it’s an invaluable social practice that results in big benefits.
Dismissing small talk as unimportant is easy, but we can’t forget that deep relationships wouldn’t
even exist if it weren’t for casual conversation. Small talk is the grease(润滑剂) for social communication, says Bernardo Carducci, director of the Shyness Research Institute at Indiana University Southeast. ＂Almost every great love story and each big business deal begins with small talk,＂ he explains. ＂The key to successful small talk is learning how to connect with others, not just communicate with them.＂
In a 2014 study, Elizabeth Dunn, associate professor of psychology at UBC, invited people on their way into a coffee shop. One group was asked to seek out an interaction(互动) with its waiter; the other, to speak only when necessary. The results showed that those who chatted with their server reported significantly higher positive feelings and a better coffee shop experience. ＂It’s not that talking to the waiter is better than talking to your husband,＂ says Dunn. ＂But interactions with peripheral(边缘的) members of our social network matter for our well-being also.＂
Dunn believes that people who reach out to strangers feel a significantly greater sense of belonging, a bond with others. Carducci believes developing such a sense of belonging starts with small talk. ＂Small talk is the basis of good manners,＂ he says.

7 . The teenage years are probably the most unsettled and stressful years in a person’s life. Teens experience significant physical, emotional, social and cognitive changes. And teens of today face more challenges as they go through more uncertain times of the 21st century.
As teens experience massive physical, social and emotional changes, the challenges are managing social expectations of ideal body images, developing their identity and finding their place in the world. In the past, a teen who was criticized for his or her larger figure or pimpled (有粉刺的) face, might feel embarrassed and dejected in school.

| E．Social media, and technological advances are posing new challenges. |
| F．Additionally, social media is a strong tool for a teen to defend himself. |
| G．The challenge for a teen today is preparing for a largely unknown future. |
8 . A vast majority of people usually argue that cycling can make a significant contribution to our world. In reality, there is a gap between desired and actual numbers. In Germany, for instance, only 20% of the everyday short-distance trips are covered by bicycle. When enquiring about the causes, researchers found one point repeatedly tops the list: the perceived or potential risk on the bike routes used. Increasing the share of cycling trips thus depends crucially on well-developed bike paths.
However, designing efficient bike path networks is a complex task that involves balancing a variety of limitations while meeting overall demand. In addition, many districts are confronted with a shortage of funds available for improving the infrastructure. Researchers propose a new approach to generating efficient bike path networks. This considers demand distribution and the route option of cyclists based on preferences for secure outings. Typically, minimizing the travel distance is far from the solely goal. Aspects such as attractiveness of a route are also taken into account.
Under real conditions, a bike path network is created by constantly adding bike paths to more streets. This time, researchers start with an ideal, complex network, in which all streets in a city are equipped with a bike path. In a virtual process, they gradually remove less used bike path sections from this network. The route selection of cyclists is continuously updated. Thus, a series of bike path networks is created and is always adapted to the current usage. Each stage of it corresponds to a variant that could be carried out with less financial support.
“We illustrate the applicability of this demand-driven planning for crowded urban areas of Dresden and Hamburg,” explains researcher Christoph Steinacker. “We are approaching a real-life issue here using the theoretic toolbox of network dynamics and compare efficient bike path networks under different conditions.”

10 . When evaluating people on various psychological tests, psychologists often distinguish between markers of absolute performance and relative performance. Absolute performance reflects the raw measurement of something, like the time it takes to run a mile. Relative performance is how a person rates in relation to their peers, as in what place a runner gets in a race.
The standards we use to evaluate ourselves are almost always relative, as we compare ourselves to our peers and the standards that are most familiar to us. For instance, in my private practice, I have one patient I will call “Omar” who is dependent on social services and makes less than $30,000 per year at his job. While this level of poverty would lead most people to wake up depressed each day, Omar is one of the most optimistic and appreciative individuals I know. Why? Because most of his closest peers — his siblings and friends from childhood — have lives far worse than his.
In contrast to Omar, I have another patient, an adolescent I’ll call “Lena”, whose family has property over $5 million. Lena, however, lives in an upper-class neighborhood where her family is at the lower end of the income level. Though Lena's family allows her to enjoy possessions and experiences that less than I percent of her peers across the world can share, she consistently feels “less than”. Why? Because Lena doesn't compare herself to the rest of the world; This is too abstract an exercise for her, as it would be for most of us.
Accordingly, whether a psychologist is psychodynamic or cognitive-behavioral, therapy (疗法) with individuals struggling with situational or psychological depression aims to solve the problems associated with basing one's self-worth on comparisons with others. Psychologists try to help people focus on personal growth around the achievement of concrete goals in line with their values. independent of the achievement of others. For all of us, defining these goals, especially during Periods of emotional calm, can go a long way in helping us to avoid the trap of relativity that often leads to situational and psychological depression.
