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.

1.What can be inferred about Aquaman and Ursula?

A. They can read minds.

B. They can breathe underwater.

C. They often cause huge disasters.

D. They can’t live underwater.

2.What can we learn about AMPHIBIO?

A. It can produce oxygen in the water.

B. Its user can communicate with others from their mind.

C. It is the unique useful tool against the threat of rising sea levels.

D. The designer drew his inspiration from a certain natural species.

3.Why did the author mentioned the rescue of the boys in Thailand?

A. To present the success of the new device.

B. To compare the new device with the old one.

C. To prove the advantage of the new device.

D. To show the new device is easily 3D-printable.

4.What is the author’s attitude to the future of the new design?

A. Objective. B. indifferent. C. Doubtful. D. Critical.

Do you find it hard to memorize words? You must not be the only one. It could be 1.(help) if you say the words aloud. But this often isn’t good in a quiet classroom.

Now, researchers from the University of Waterloo, Canada, have come up 2.a new idea. They suggest 3.(draw) a picture of what you are trying to memorize!

The researchers did a study 4.(base) on the idea. They first gave a group of students some words such as “apple” or “balloon”. Then they gave the students 40 seconds, during 5.the students could either write the words again and again, or draw a picture.

When the time 6.(be) over, the researchers asked the students to do something else, like sing a song. After that, they gave the students 60 seconds to write down as many words 7.they could remember. The results showed that those who drew the words did a much 8.(good) job than those who wrote them.

So the next time you are having a hard time memorizing a word, 9.(draw) it! No worries if you’re not good at drawing. The 10.(research) say the quality of the drawing doesn’t matter at all.
