Your smart phone may have hurt you before you realize it. Don't be addicted to it. Put your phone away, OK?
1.Cyber Sickness
Also called “digital motion sickness”, symptoms that range from headaches to woozy feelings can occur when you quickly scroll on your smart phone or watch action packed video on your screen. 1.. Your sense of balance is different from other senses in that it has lots of inputs. When those inputs don’t agree, that’s when you feel dizziness and sickness.
2. Text Claw
It is the unofficial term for soreness and muscle contraction felt in the finger, wrist and forearm after heavy smart phone use. 2.. So if you’re always on your phone, it makes sense to feel discomfort in your hands and forearms.
3. Eye Strain
Do you stare at a screen for hours on end? If you’re reading this, you very well might. 3.. Staring at your digital devices for a long time can lead to dry eyes, headaches and tiredness, which can decrease your productivity. Experts suggest taking screen breaks every 20 minutes.
4. Text Neck
Similar to the claw, text neck---discomfort in the neck and spine happens when you spend a long time looking down at your smart phone. 4.. Being mindful of how far your neck bends when you’re on your phone---- and bending it back to an upright position can help reduce the risk of text neck.
5. Pedestrian safety
Pedestrian deaths are on the rise because too many smart phone users engage in distracted walking. While focused on the cyber world, many of us can lose reality of the physical one. Elemental pedestrian safety knowledge is compromised by technology, and the risks are scary. 5..
A. We should taking breaks for a while.
B. The sensation results from a mismatch between sensory inputs.
C. Remember that pedestrian safety is more important than smart phone.
D. The habit may lead to people requiring medical spine care at a younger age.
E. To avoid injury or worse, put your phone away until you’ve reached a safe spot.
F. Any specific motor activity can cause pain in the tendons (筋) and muscles when done repeatedly.
G. Any activity that requires active use of your eyes---driving and reading included---can cause eye tiredness.

You want a smart phone, but just how smart do you want it? How about one that can read your mind? Well, that phone may well be on its way...
Justin Rattner, chief researcher at Intel, says that technology has developed to the point that “context-aware computing (情景感知计算)”, an idea that’s been around for twenty years, is becoming more of a reality.
That could lead to a phone that acts as a mind reader in your pocket. But rather than simply collect secrets about you, the device could do things with that information, such as predict what you might do next and make suggestions.
Rattner gave a few examples during his speech at Intel’s developer conference in San Francisco recently.
Among them is a software that Intel worked on with Fodor’s Travel, a traveling website. It learns what types of foods you like to eat and what types of places you like to visit, based on searches you type into the phone or places you searched using GPS (全球定位系统). The software makes similar recommendations when you visit a new city.
Tech companies are already working to predict what people want. Search engine Google, movie-rental service Netflix, and online radio service Pandora try to guess what people want even before they know they want it.
Putting those types of functions together with the other information that phones collect about people could pave the way for even more helpful mobile phones, Rattner said.
A challenge is training computers to look at data from “hard sensors (传感器)” (which measure place, movement, temperature and the like) and combining those findings with data from “soft sensors” (such as calendar appointments and Web browsing history).
For example, your phone could tell that you have just left school and seem to be on your way home—a location it might know from your address book. It could then tell you the best route around traffic.
Rattner added that researchers are even making steps toward the final goal—a computer understanding of thoughts.

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.

You can’t see it with your own eyes,but your smart-phone is likely to be covered with bacteria- perhaps even more so than your toilet seat. That's a lot of dangerous microbes(微生物)floating around, and yes, it is terribly dirty.
In this age of global travel and trade, it’s more important than ever to cut down on possible routes of infection and to stop bacteria and viruses spreading from person to person. Part of that means making sure your phone isn’t sending anything more than data.
And besides the potential health risks of a dirty phone, there's also the simple annoyance of looking at a screen that’s covered in fingerprints and other oily spots that are part of life with a smart-phone.
In short, you’ve got plenty of reasons to regularly give your phone a thorough clean. Not just during a pandemic(大流行病),either-we should be thinking about keeping our phones bacteria free all the time, says microbiologist Paul Turner, a professor at Yale University.
After all, we touch our phones all the time and many of us are relatively careless about cleaning them. “It sets the stage for kind of concern,” Turner says. “People could be handling phones and picking up any bacteria or virus that can attach to a surface and survive for a period of time.”
Take SARS-CoV-2, the corona- virus(冠状病毒)that causes the COVID-19, for example. Scientists are still trying to get solid evidence, but early research suggests that it can survive on plastic or stainless steel(不锈钢)surfaces for two or three days. That means you could be washing your hands perfectly well, but immediately picking the virus up again as soon as you reach for your phone.
You could be doing everything right(like washing your hands and staying away from people),but
if there’s a contaminated surface in your home or your pocket, you could expose yourself to the virus anyway, Turner says.
1.Why does the author mention the toilet seat?
A.To draw a vivid picture of a dirty phone.
B.To show how dirty a toilet seat is.
C.To add some background information.
D.To introduce a topic for discussion.
2.What can we learn in Paragraph 6?
A.Simply washing our hands is not enough.
B.Scientists have got solid evidence of the COVID-19.
C.The corona-virus can survive on smooth surfaces for 2 or 3 weeks.
D.The author suggests washing our hands before using our phones.
3.What do the underlined words “contaminated surface” refer to in the last paragraph?
A.A stainless steel. B.A deadly virus.
C.A clean phone. D.An infectious phone.
4.What is the main idea of the text?
A.You may get infected with your dirty phone.
B.You are supposed to wash your hands.
C.You’d better clean your dirty phone.
D.You’d better throw away your dirty phone.

Phone Soap: Charge and Clean Your Phone
You may charge your phone every day, but do you clean your phone as much? Whatever your hands touch, your phones touch. It has been discovered that some phones have 18 times more bacteria and viruses than any surface in a public restroom. So it probably won’t surprise you that a 2011 University of London study found that one in six of our phones have bacteria and viruses on them—specifically, the bacteria called E. coli.
The research on bacteria and viruses led to the invention of Phone Soap. It is not actually liquid like dishwasher soap. It is a phone charger that uses the electromagnetic radiation (辐射) used in hospitals to kill 99.9 percent of bacteria and viruses, cleaning your phone while it charges.
“There are really certain types of bacteria and viruses that we should not be in touch with, and they are really on our phones,” says Wes Barnes, the Phone Soap co-founder. It all started while his cousin and co-founder, Dan LaPorte, was in his cancer research lab at college. “He realized he got the idea of getting rid of bacteria and viruses on the phones,” said Barnes. “In the lab they used UV-C light for destroying them. He realized this would be the fastest, most powerful way to kill any bacteria and viruses living on electronic machines.”
Phone Soap looks like a little metal suitcase. Your phone rests in to charge and get cleaned at the same time. Instead of plugging your phone into the wall, you’d plug it into the Phone Soap charger box. The process only takes a few minutes but, Barnes says, “The idea is that you can leave it in there overnight if you want to keep charging. Reflective paint keeps the light completely around the phone so it cleans the phone fully.”
The co-founders spent 2013 finding the right companies and they started shipping the product in late November. By last week’s International Consumer Electronics Show in Las Vegas, Phone Soap was all grown-up. Both co-founders have left their previous jobs and are selling Phone Soap nonstop. “We’re shipping almost more than we can handle each day,” Barnes says. “It’s been a great adventure.”
