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.

You see your phone light up from the corner of your eye and quickly reach for it. What started as a simple notification（通知）check snowballs into an hour-long period as you look through rows of notifications and endless social media feeds.

This is by design. Tech companies such as Google and Facebook have spent years working to make consumer technology as addictive as possible. After all, time spent with their products could equal big profits for the company.

However, that’s starting to change. Apple takes action with the introduction of tools in its new operating system aimed at informing users to better manage their smartphone usage and parental controls that allow parents to better monitor and control their children’s phone time.

Google also offers a “Wind Down”feature to set at bedtime, which automatically puts the phone into“Do Not Disturb”.No notifications will show up on your phone, and losing all color on-screen is certainly a cause to put your phone away.

There are still no clear guidelines on what causes tech addiction, but it’s a growing concern likely on the minds of parents everywhere as they see their kids’ faces constantly glued inches away from a screen. And everywhere you go, you’re all but guaranteed to see people buried in their phones.

Apart from Apple and Google, Facebook deserves a fair amount of blame, as CEO Mark Zuckerberg acknowledged in a blog post earlier this year. The social network announced plans to roll out changes aimed at making interactions more meaningful.

“By making these changes, I expect the time people spend on Facebook will go down,”Zuckerberg said. “But I also expect the time you do spend on Facebook will be more valuable. And if we do the right thing, I believe that will be good for our community and our business over the long term too.”

1.What has been done to change phone addiction?

A.Making some color disappear on screen. B.Offering functions to reduce phone use.

C.Improving consumer technology. D.Stopping sending messages.

2.What does "the social network" underlined in the Paragraph 6 refer to?

A.Google. B.Apple.

C.A blog post. D.Facebook.

3.What does Zuckeberg mean in the last paragraph?

A.Facebook in expecting fewer people to use it.

B.It’s valuable for people to do the right thing on Facebook.

C.People should spend time on Facebook as little as possible.

D.Facebook and its consumers will have a win-win relationship.

4.What can be a suitable title for the text?

A.Fighting against Screen Addiction

B.Making Tech Addiction by Design

C.Controlling Children's Phone Time

D.Letting Phone Interactions Meaningful

Did you move your way into work this morning with your head down? Obviously, you did. It's Wednesday and, if you are in New York, it’s a rainy, annoying day. 1. Walk like a happy person and you’ll actually feel happier.

In the study, people walked on treadmills (跑步机) for 15 minutes. Around them were cameras with sensors that picked up their movements, and in front of them was a screen displaying a gauge (计量器) that moved to the left if they walked like they were depressed, and to the right if they walked like they were happy. 2.

Before the task, they were shown a list of words, some positive (pretty) and some negative (afraid, anxious). 3. The people who walked like a depressed person ended up recalling more negative words and (slightly) fewer positive words than the people who'd merrily bounced along on their treadmills. This means that the people who'd walked as if they were sad did, in fact, end up feeling sadder.

4.Harvard social psychologist Amy Cuddy found that if you stand like a powerful person, you'll feel more powerful. My high school swim coach used to tell us to fake (假装) it till you feel it; science as of late seems to be suggesting that she had a point. 5.Have a try and walk.

A.So now are you still sad?

B.They just remember the positive words.

C.Their arms swing at their sides as they go along.

D.But there's new evidence that you can walk yourself right out of it.

E.But the people in the study didn't know what the gauge was measuring.

F.That's to say, you can change your mood simply by changing your movement.

G.After they stopped, they were asked to write down as many words as they could.
