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.

Much meaning can be conveyed, clearly, with our eyes, so it is often said that eyes can speak.
Do you have such kind of experience? In a bus you may look at a stranger, but not too long. And if he is sensing that he is being stared at, he may feel uncomfortable. The same in daily life. If you are looked at for more than necessary, you will look at yourself up and down, to see if there is anything wrong with you. If nothing goes wrong, you will feel angry toward other's stare with you that way. Eyes do speak , right ?
Looking too long at someone may seem to be rude and aggressive. But things are different when it comes to stare at the opposite sex. If a man glances at a woman for more than 10 seconds and refuses to remove his gaze, his intentions are obvious, that is, he wishes to attract her attention, to make her understand that he is admiring her.
However, the normal eye contact for two people engaged in conversation is that the speaker will only look at the listener from time to time, in order to make sure that the listener does pay attention to what the former is speaking, telling him that he is attentive. If a speaker looks at you continuously when speaking, as if he tries to control you, you will feel disconcerted. A poor liar usually exposes himself by looking too long at the victim, since he believes in the false idea that to look straight in the eye is a sign of honest communication. Quite the contrary, in fact, continuous eye contact is confined to lovers only, who will enjoy looking at each other tenderly for a long time, to show affection that words cannot express. Evidently, eye contact should be done according to the relationship between two people and the specific situation.
1.When a person stares at another one, it may be
① there is something wrong with another person
② a man wants to draw a woman's attention
③ a poor liar is telling a lie to another person
④ a person wants to say something but forgets
A. ①②④ B. ①②③
C. ②③④ D. ①③④
2.Why does a person look at another one from time to time in normal conversation?
A. To show the speaker is polite. B. To attract the listener's attention.
C. To make sure the listener is listening. D. To show affection words can't express.
3.The meaning of the underlined word in the last paragraph is close to
A. unfair B. unsatisfied
C. unfortunate D. uncomfortable
4.What is the best title for the passage?
A. Eyes can speak. B. Eyes can tell lies.
C. Eyes are important. D. Eyes can show affection.

You can’t see your sleeping pets brain waves, but its behavior can tell you when your cat might be dreaming. If you watch closely, you’ll see that as she falls asleep, her breathing becomes slow and regular with her body still. She has entered the first stage of sleep, called slow-wave sleep. After about 15 minutes you’ll notice a change in her breathing. Her eyes move under her closed lids, her paws twitch (抽动) and she flicks (尤指用手指或手快速地轻抚) an ear. She has entered dreaming. Although she twitches and makes little grunting (嘟嘟) noises, messages from her brain to the large muscles in her legs are blocked, so she can’t run about. She is in a state of “sleep paralysis (麻痹)”.
Michel Jouvet, a French scientist, interrupted their sleep paralysis. Even though they were completely asleep, the dreaming cats began to run for balls that Jouvet couldn’t see and arched (弓起) their backs at unseen enemies. He figures he was watching them act out their dreams! Obviously, the dreaming cats seemed to be practising important cat skills: following, pouncing (猛扑), and fighting.
In another study, Matt Wilson recorded rats brain waves while they learned mazes (迷宫). One day, he left the brain-wave-recording machine on while the rats fell asleep. The pattern of brain waves in the sleeping rats matched the pattern from the maze so closely that Wilson could figure out exactly which part of the maze each rat was dreaming about!
Many researchers now think that in both people and animals, one purpose of dreams is to practise important skills and figure out recent caning. This may explain why so many people dream about fighting and escaping, skills that were probably important to our ancestors, and why dreaming affects our ability to learn.
Do all animals dream? From looking at the brain waves of sleeping animals. How often animals dream seems to be tied to body size. Cats dream about every 15 minutes, mice every 9 minutes, and elephants every 2 hours. And though cows and horses usually sleep standing up, they only dream when lying down.
1.What does Michel Jouvet find in his study?
A. The dreaming cats are in a state of body paralysis.
B. The dreaming cats often practise their important skills.
C. The eyes of dreaming cats moved while bodies are still.
D. The muscles of the dreaming cats are blocked to move.
2.What can you know about dreaming from the passage?
A. Dreaming a lot can help humans learn more.
B. Learning mazes is the basic skill for cats to learn.
C. Rats often dreams to make certain their recent learning
D. Fighting and escaping are not important skills for ancestors.
3.Which animal may dream most frequently?
A. Rats. B. Dogs.
C. Cows. D. Elephants
4.How does the author develop his passage?
A. By making comparisons. B. By using figures
C. By telling stories D. By showing facts

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.
