If you could have a superpower, what would it be? Other than flying and communicating with someone from his mind (which, let’s be honest, would probably actually be awful), breathing underwater is one of the favorites. You can hang out with Aquaman and Ursula, and when the end of the world comes and we’re all living under water, you’ll be fine.
With this in mind, a student at the Royal College of Art, London has designed a 3D-printed amphibious garment called AMPHIBIO — essentially a set of gills(鳃) — for this very purpose.
According to Jun Kamei, a biomimicry designer and materials scientist, it is "for a future where humankind lives in the water".
With the world set for a global temperature increase of 3.2°C (5.7°F) by 2100, rising sea levels are a very real threat to large coastal cities, potentially affecting up to 2 billion people — or 26 percent of the current global population.
Kamei’s little device uses a specially designed porous(多孔的) material that fills oxygen again in the water and releases carbon dioxide. It is inspired by water-diving insects that create their own little scuba diving set by creating a protective bubble of air around their body thanks to their water repellent(防水的) skin.
The technology is easily 3D-printable too, which will be great when we need them together. These "gills" could replace heavy and clumsy scuba equipment, making it more similar to free diving but for longer. This could have immediate applications for underwater rescue plans — the 12 boys rescued by divers from a flooded cave in Thailand, for example, where it took weeks to work out how to get the boys and the vital breathing equipment through those narrow tunnels.
So far, the tech has only been tested as a working prototype, not actually on humans, so the dream may have to be on hold for now. And scaling up and testing on humans is Kamei’s next plan. This may sound unbelievable, but Kamei insists he has a much more optimistic vision of the future.

Who cares if people think wrongly that the internet has had more important influences than the washing machine? Why does it matter that people are more impressed by the most recent changes?
It would not matter if these misjudgments were just a matter of people’s opinions. However, they have real impacts, as they result in misguided use of scarce resources.
The fascination with the ICT(Information and Communication Technology) revolution, represented by the internet, has made some rich countries wrongly conclude that making things is so “yesterday” that they should try to live on ideas. This belief in “post-industrial society” has led those countries to neglect their manufacturing sector(制造业), with negative consequences for their economies.
Even more worryingly, the fascination with the internet by people in rich countries has moved the international community to worry about the “digital divide” between the rich countries and the poor countries. This has led companies and individuals to donate money to developing countries to buy computer equipment and internet facilities. The question, however, is whether this is what the developing countries need the most. Perhaps giving money for those less fashionable things such as digging wells, extending electricity networks and making more affordable washing machines would have improved people’s lives more than giving every child a laptop computer or setting up internet centres in rural villages, I am not saying that those things are necessarily more important, but many donators have rushed into fancy programmes without carefully assessing the relative long-term costs and benefits of alternative uses of their money.
In yet another example, a fascination with the new has led people to believe that the recent changes in the technologies of communications and transportation are so revolutionary that now we live in a “borderless world”. As a result, in the last twenty years or so, many people have come to believe that whatever change is happening today is the result of great technological progress, going against which will be like trying to turn the clock back. Believing in such a world, many governments have put an end to some of the very necessary regulations on cross-border flows of capital, labour and goods, with poor results.
Understanding technological trends is very important for correctly designing economic policies, both at the national and the international levels, and for making the right career choices at the individual level. However, our fascination with the latest, and our under valuation of what has already become common, can, and has, led us in all sorts of wrong directions.

We’ve all had cases where we’ve waited just a bit too long to pay an electric bill or speeding ticket. But one man, from California by reasonable assumption，who goes by “Dave”，recently took procrastination (拖延) one step further, by paying a parking ticket almost a half-century after it was given.
In December 2018, the Minersville Police Department in Pennsylvania received a letter in the mail. Whoever wrote the letter decided it was best to keep his name somewhat unknown，so he put the return address as “Wayward Road，Anytown California” under the name “Feeling guilty”.
When the officers opened the envelope，they found a brief letter, along with a $5 bill, and a parking ticket dating all the way back to 1974. The note read，“Dear PD，I've been carrying this ticket around for 40 plus years always intending to pay. Forgive me if I don't give you my info. With respect，Dave.”
Even though the initial parking ticket was only for $2, “Dave” must have felt awfully guilty because he left 150 percent，or $3, in interest.
Michael Combs, the Police Chief of the Minersville Police Department, stated in an interview that the same ticket would cost about $20 if it were given today. Combs went on to share that the original ticket from 1974 was given to a vehicle that had an Ohio license plate.
Because there was no system for tracking tickets given to out-of-state cars back then，“Dave” could have gotten away with never paying the $2 fine. But apparently，guilt got the best of him，and he decided to finally cough up the money more than 40 years past its due date.
1.How much do we know about “Dave”？
A. He lives in Wayward Road，Anytown California.
B. His car probably came from Ohio at that time.
C. The police are trying to find out more about him.
D. “Dave” is of course the man’s real name indeed.
2.Why didn’t “Dave” pay for the parking ticket until recently?
A. He completely forgot about it in the past 44 years.
B. He didn’t find it until almost half a century later.
C. He didn’t pay for it just because of procrastination.
D. He failed to find out who he should pay the money to.
3.What drove “Dave” to pay for the parking ticket at last?
A. A strong sense of guilt.
B. Fear of being tracked by the police.
C. Worry about being fined more.
D. Sudden change of his financial situation.
4.Which of the following can be the best title?
A. Police Chief of the Minersville Police Department Shares a Story
B. Parking Ticket Carried Around for Almost Half a Century from Ohio
C. Unusual Letter Comes from Wayward Road, Anytown California
D. Mysterious Procrastinator Finally Pays 44-Year-Old Parking Ticket

People always say that life can 't go on good all the time, because we will meet all kinds of difficulty. When we are students, we want to get improving and get high marks in the exams. When we graduate and find the job, we need to finish all the tasks what are given to us on time. Even after retiring, we still come across something difficult in our life. Although life is difficult, we should get used to them. When we face with the difficult time, we ought consider it as a test for us. When we get through it, we will gain value experience. The pleasure we get make us proud.
