1 . How to Avoid an Internet Addiction
It may seem like everyone surfs the web these days. But if you can’t have interest in other aspects of your life because of the Internet, you may be on your way to an Internet addiction. You might fear you’re the only one who has experienced that feeling.
More and more people in the world are becoming addicted to the Internet, and you are not the only one with this problem. So do not be embarrassed. Just be brave to admit that you are on your way to an Internet addiction. And then find others with the same problem and help each other beat it.
Set aside limited time for computer use.
Make sure not to turn it on too many times a week. If you have a laptop, make sure to put it somewhere that you can remember but not somewhere that you see every day. Try keeping the lid closed when you are not using it.
Call people instead of sending instant messages or texts.
If you are free on weekends, call friends and ask them to go outside to do something you enjoy, like playing a sport. This will take your mind off the computer.
Use an alarm clock or timer (计时器).
Before using your computer, decide on a time limit such as 30 minutes. Set the clock or timer and make sure that you get away from the computer when the time is up. Alternatively create a shutdown timer on your desktop.
| A．Being addicted to it is quite normal. |
| B．Admit you are at risk of an addiction. |
| C．The truth, though, is that it’s quite common to be an addict. |
| D．When the computer is not looking at you, you are less likely to use it. |
| E．This can be programmed to shut down your computer after the set time. |
| F．If you have a problem on weekdays, phone your friends or ask for help in person. |
| G．This will prevent you from using the Internet so often or going on to another page. |

4 . Blind people have long desired for brightness, but scientists don’t have the technology. To bring that one step closer to reality, Zhiyong Fan, a materials scientist of the Hong Kong University of Science and Technology, developed a new artificial eye recently. The device, which is about as sensitive to light and has sharper vision and a faster reaction time than a real eyeball, may outperform human eyes.
The human eye owes its wide field of view and clear eyesight to the retina (视网膜) — an area at the back of the eyeball covered in light-detecting cells. The design for a new artificial eye is based on the structure of the human eye and uses a friendly light-sensitive material. At the back of the eyeball, an artificial retina is lined with Nan scale light sensors (纳米级光感器). Those sensors measure light that passes through the lens (晶状体) at the front of the eye. Wires attached to the back of the retina send signals from those sensors to the processor, similar to the way nerve networks connect the eyeball to the brain.
“In the future, we can use this to replace damaged human eyes,” says the lead designer. In theory, this artificial eye could see more clearly than the human eye, because the artificial retina contains about 460 million light sensors per square centimeter while a real retina has about 10 million light-detecting cells per square centimeter. Besides, the artificial eyeball records changes in lighting faster than human eyes can — within about 30 to 40 milliseconds, rather than 40 to 150 milliseconds. Although its 100-degree field of view isn’t as broad as the150 degrees a human eye can take in, the device can see as well as the human eye in poor light.
Hongrui Jiang, an electrical engineer at the University of Wisconsin, though, thinks engineers need a much more practical and efficient way to produce vast series of tiny wires on the back of the artificial eyeball to give it superhuman sight, which is super hard to achieve.

5 . Along with a rising number of space missions by government agencies and private industries, comes a fresh set of problems for Earth: potentially dangerous space junk (太空垃圾).
A recent study published in the scientific journal Nature Astronomy concluded “that current space practices have a 10 percent chance of one or more deaths over a decade”. In other words, according to researchers from the University of Victoria and the University of British Columbia, there’s roughly a one-in-ten chance that the next decade will witness falling space junk kill someone.
The space junk orbiting the earth is an unfortunate by-product of our desire to explore and document space. According to 2021 figures from NASA and the Department of Defense’s Space Surveillance Data, the agencies were actively tracking more than 27,000 pieces of space junk, most of which are larger than a softball and that casually orbit the planet. The floating space junk is certainly a problem, but not all the objects must come down, and, in fact, a number of pieces simply burn up in the atmosphere. Sometimes those objects, particularly large ones like used rocket attachments, give in to gravity and fall back down to Earth to be dealt with once again by their human makers. But typically, people don’t die or even get injured by this phenomenon — because many of the falling pieces crash into the ocean.
They also have to deal with the unsettling feeling of knowing that large rocket pieces can just fall from the sky and that it might affect people in certain parts of the world more than others.
This poses an obvious safety risk to people on the ground. “When some large parts of space junk return to Earth, the parts of their mass survive the heat of atmosphere. Many of the surviving pieces are potentially dangerous, giving serious risks on land, at sea, and to people in airplanes,” the study explains.
