If you’re a gamer who’s constantly glued to your phone, it could be time to ask for medical help.

On June 18, 2018, the World Health Organization（WHO）officially listed “gaming disorder” as a mental health condition. 1.

“Video gaming is like a non-financial kind of gambling （赌博）from a psychological point of view,” Mark Griffiths, a professor from Nottingham Trent University in the UK, told the Associated Press（AP）. “Gamblers use money as a way of keeping score, while gamers use points.”

2.“People need to understand this doesn’t mean every child who spends

hours in their room playing games is an addict, otherwise doctors are going to be flooded with requests for help,” Joan Harvey, a spokeswoman for the British Psychological Society, told AP.

3. For example, a 21-year-old Chinese woman surnamed Wu in Guangdong province went blind in one eye after playing the mobile game King of Glory for a whole day. “On days when I have no work, I usually get up at 6 am, eat breakfast and play until 4 pm,” she told the South China Morning Post.　 “Then I’ll eat something, have a nap（小睡）and play until 1 am.”

Wu isn’t alone. According to a study published by China Youth Daily, about one in five young Chinese people play online video games for at least four to five hours per day. 4. In April, the Ministry of Education issued a notice asking Chinese schools and parents to prevent students from becoming addicted to the Internet and games.

Other countries have also taken action.　 5. Meanwhile, in Japan, some mobile phones have a special mode for children that lets their parents control what games they can download and how long they can play.

A. This means it’s now on the same list as other mental illnesses.

B. Thankfully, measures have been taken to deal with the problem.

C. We often see people around us playing games on their mobile phones.

D. In South Korea, children are forbidden to play video games after midnight.

E. WHO’s main work is to improve the mental health of individuals and society.

F. But if you lose control over your gaming habits, you’ll face serious problems.

G. However, it doesn’t matter if you play your favorite game now and then.

“If we can set it up so you can’t unlock your phone unless you’ve got the right fingerprint(指纹),” Barack Obama asked last Tuesday, “why can’t we do the same thing for our guns?” For this reasonable-sounding question, the president was applauded throughout the media.

As it happens, though, there is a good answer to this question: there is no market for guns that work just some of the time. Guns are simple things designed to operate as easily and reliably as possible. The introduction of electronics eats away this simplicity, and to a degree that is absolutely unacceptable to the consumer. As President Obama well knows, the fingerprint software on his phone works rather erratically: Often it takes a user two or three tries to log in; occasionally, it falls asleep deeply and obeys the password. When this happens on an phone, the user is mildly inconvenienced. If this were to happen on a gun, the user would be dead. There is a reason that modern smartphones put the camera function outside of the authentication(认证) process.

How could we possibly think that guns are the same as other commercial products? It is true that, say, cars have become considerably safer over the last few decades; true, too, that “research” has contributed to this improvement. But it matters enormously that a car is not intended to hurt people, and that in a perfect world nobody would ever be injured by one. Can we say the same of guns? Of course not. Guns are killing machines, designed explicitly to do damage to living things. In fact, they have no other purpose. As such, the salient question before any free people is not “are guns dangerous?”, they are, but “who gets them, and why?”

This is not to say that nothing at all can be done to improve public safety. On an individual level, gun owners should do everything to ensure that their guns are kept away from children, and, where possible, they should train themselves in case they are ever called upon to shoot in anger. At the national level, the combination of better policing and economic growth can help to reduce crime—and, indeed, it has. In 1993, gun crime was more than twice as common as it is now, and there were many fewer guns in circulation. Ugly as it is in its own right, that we have reached the point at which two-thirds of all guns-related deaths are deliberately self-inflicted is a small victory.

How to address those deaths that remain? That is a tricky one. I do not know the answer, and nor, frankly, does anybody else. But selling fantasies to the ignorant is not going to cut it.

1.What does the writer mainly argue in this passage?

A. Gun crime has been greatly reduced.

B. The idea of smart guns is not realistic.

C. Gun control will not succeed in America.

D. Guns-related deaths deserve public attention.

2.The underlined word “erratically” in Paragraph 2 probably means ________.

A. with effectiveness

B. with passion and energy

C. in an unpredictable manner

D. in a reasonable and fair way

3.The writer supports his ideas in Paragraphs 2 and 3 mainly by ________.

A. analyzing statistics

B. presenting problems and solutions

C. quoting the authorities

D. making comparisons and contrasts

4.Which of the following might the writer NOT agree with?

A. Few know how to deal with guns-related deaths.

B. Efforts to improve public safety have partly paid off.

C. The nature of guns distinguishes them from other products.

D. Guns using fingerprint software can risk the lives of the users.

One of the things that makes your smart-phone so smart is that if you pull it out in the sun, it senses that—and dials up the screen brightness to compensate. But it’s not a perfect solution.

“First of all, it’s still not bright enough—you have to remember how respectable sunlight is.” Shin-Tson Wu, a physicist at the University of Central Florida. The other problem, he says of the brightened screen, is it kills the battery. So Wu and colleagues have produced a battery-sparing alternative: an anti-reflective screen-coating. Based on the eyes of moths. “Nature is so rich! We can learn a lot from nature. “The thing Wu and others have learned about moth eyes, is that they’re uneven, dotted with tiny projections. That uneven surface reduces the reflection of light off their eyes- thought to help the bugs escape predators (捕食者), and see better in low light. So Wu and his team built a similar surface with tiny dimples (凹), to cut down on glare. He says the dimpled coating could improve the readability of a screen by five to 10 times, compared to a normal smart-phone screen. The details are in the journal Optica.

The tech hasn’t been commercialized yet, and that could take a few years. Which gives researchers time to take advantage of another property of these surfaces: they’re flexible. Meaning the possibility of bendable displays. Combine that with the bendy batteries we reported on in a recent podcast(播客), and it looks the smart-phones of the future could be set for a real transformation.

1.Why do the researchers develop the anti-reflective screen-coating?

A.To brighten the screen. B.To make profits.

C.To take in the sunlight. D.To save the use of battery.

2.What inspired the invention of the screen?

A.The predators. B.The reflection of light.

C.The eyes of moths. D.The smooth surface.

3.How does the screen work?

A.It helps bugs escape.

B.It slows down reading.

C.The smooth surface protects our eyes.

D.The rough surface decreases the reflection of light.

4.What do the researchers expect of the screen?

A.I’ll transform itself. B.I’ll be environment-friendly.

C.I’ll reach consumers soon. D.I’ll be powered by recyclable batteries.

How to escape from a car in water

“If you get on your phone and call your parents or your sister, or 911,you will die, " says Robert May, a 21-year-old veteran （老兵）of the Indiana State. No one else will arrive in time: you have to save yourself.

Move quickly. Minivans (微型货车) might float for as long as 10 minutes. 1. In a study from the University of Manitoba, three passengers were able to exist with a child mannequin (人体模型) through a single driver-side window in just 3 seconds.

Unbuckle (揭开) your seatbelt, lower your window and climb out, ideally onto the roof of the vehicle. 2. Unfasten them from the backseat, pull them into the front and push them out of your window, oldest ones first. In May's experience, electric car windows will continue to work after falling into water. 3..

Don't open the door, water will flood in. Once full of water, the vehicle will sink fast. 4. Vehicle submersions (淹没) have one of the highest death rates of any type of single-motor-vehicle incidents, responsible for 400 deaths a year in North America.

After you get on top of your car, figure out if it makes sense to stay put or swim for dry ground. 5. Just get out first, May says.

A. From there, call for help.

B. You will be then totally out of danger.

C. Research has been done to confirm this.

D. If there are children present, attend to them first.

E. In one study, a 65-passanger bus sank in nine seconds.

F. Still, keep a small grass-breaking tool on your key ring, just in case.

G. However, the chances of survival are highest if you get out in the first 60 seconds.
