You know the feeling that you have left your phone at home and feel anxious, as if you have lost your connection to the world. “Nomophobia” (无手机恐惧症) affects teenagers and adults alike. You can even do an online test to see if you have it. Last week, researchers from Hong Kong warned that nomophobia is infecting everyone. Their study found that people who use their phones to store, share and access personal memories suffer most. When users were asked to describe how they felt about their phones, words such as “hurt” (neck pain was often reported) and “alone” predicted higher levels of nomophobia.

“The findings of our study suggest that users regard smartphones as their extended selves and get attached to the devices,” said Dr. Kim Ki Joon. “People experience feelings of anxiety and unpleasantness when separated from their phones.” Meanwhile, an American study shows that smartphone separation can lead to an increase in heart rate and blood pressure.

So can being without your phone really give you separation anxiety? Professor Mark Griffiths, psychologist and director of the International Gaming Research Unit at Nottingham Trent University, says it is what is on the phone that counts-the social networking that creates Fomo (fear of missing out).

“We are talking about an internet-connected device that allows people to deal with lots of aspects of their lives,” says Griffiths. “You would have to surgically remove a phone from a teenager because their whole life is rooted in this device.”

Griffiths thinks attachment theory, where we develop emotional dependency on the phone because it holds details of our lives, is a small part of nomophobia. For “screenagers”, it is Fomo that creates the most separation anxiety. If they can’t see what’s happening on Snapchat or Instagram, they become panic-stricken about not knowing what’s going on socially. “But they adapt very quickly if you take them on holiday and there’s no internet,” says Griffiths.

1.Which of the following may Dr. Kim Ki Joon agree with?

A. We waste too much time on phones.

B. Phones have become part of some users.

C. Addiction to phones makes memories suffer.

D. Phones and blood pressure are closely linked.

2.According to Giffiths, we get nomophobia because　　　　 .

A. we are accustomed to having a phone on us

B. we need our phones to help us store information

C. we worry we may miss out what our friends are doing

D. we fear without phones we will run into a lot of trouble

3.Where can you probably find the above passage?

A. In a research report. B. In a fashion brochure.

C. In a science textbook. D. In a popular science magazine.

Have you ever wondered when dogs first became “man’s best friend” and the world’s favourite pet? If you have then you’re not alone. When and where dogs first began living side-side with humans are questions that have stirred hot debate among scientists. There are a few hard facts that all agree on. These include that dogs were once wolves and they were the first animal to be domesticated(驯养) by humans. They came into lives some 15000 years ago, before the dawn of agriculture.

Beyond that, there is little agreement. The earliest bones found that are unquestionable dogs and not wolves date from 14,000 years ago. However, 30,000-year-old skulls have been discovered in France and Belgium that are not pure wolf and some scientists think could be dogs.

With such puzzling evidence, many scientists are now turning to DNA to find out when and where dogs were first domesticated. In one research project, tens of thousands of blood samples have been taken from street dogs around the world. The plan is to compare them with those of wolves. It’s even possible to analyse DNA from ancient bones. Tiny pieces of the 30,000-year-old skulls mentioned earlier are currently being studied, and another DNA study has already shown that ancient dogs preserved in the Alaskan ice-fields evolved from Asian wolves, not American ones.

Indeed, the ancient DNA may turn out to be more informative than the DNA of living dogs. Because dogs have accompanied humans around the world for thousands of years, their current distribution may tell us very little of their origins. This is why different groups of scientists believe that dogs variously originated in eastern Asia, Mongolia, Siberia, Europe or Africa.

But why were the animals domesticated in the first place? The most recent theory is that dogs domesticated themselves, initially living in and around our ancient villages to eat any food thrown out. Today, this is a way of life still shared by three -quarters of a billion unowned dogs worldwide.

1. Which is the only statement generally agreed on by scientists studying dogs?

A. They originally were used as farm animal

B. They evolved from wolves found in Europe

C. They helped the development of agriculture

D. They were the first animal to be kept as pets

2. Why does the writer first mention the 30,000-year-old animals skulls?

A. To show that dogs were much larger in the past

B. To prove that dogs developed from Asian wolves

C. To suggest that dogs may have evolved much earlier

D. To argue that dogs were first kept in France and Belgium

3. How did scientists determine the origins of the ancient dogs found in Alaska?

A. By examine the animals’ DNA

B. By analyzing the age of their bones

C. By studying the shape of their skulls

D. By comparing them with modern dogs

4. Why did dogs start living with humans?

A. Because they were attracted by food

B. Because they were trapped by humans

C. Because they couldn’t survive in the wild

D. Because they were trained to protect villages

Have you ever pressed the pedestrian button at a crosswalk and wondered if it really worked?　 They’re called “placebo(安慰剂）buttons”一buttons that mechanically sound and can be pushed，but provide no functionality.

In New York City, only about 100 of the 1, 000 crosswalk buttons actually function. Crosswalk signals were generally installed before traffic jam had reached today’s levels.

But while their function was taken over by more advanced systems—such as automated lights or traffic sensors — the physical buttons were often kept, rather than being replaced at further expense. Other cities，such as Boston，Dallas and Seattle，have gone through a similar process, leaving them with their own placebo pedestrian buttons. In London, which has 6, 000 traffic signals，pressing the pedestrian button results in a reliable “Wait” light. But that doesn’t necessarily mean that the “green man”— or “pedestrian stage” in traffic signal design profession — will appear any sooner.

“We do have some crossings where the green light comes on automatically, but we still ask people to press the button because that enables accessible features,’’ said Glynn Barton, director of network management at Transport for London.

These features, such as blind tracks and hearable traffic signals, help people with visual disorder cross the road and only function when the button is pressed. As for the lights, a growing number of them are now combined and become a part of an electronic system that detects traffic and adjusts time frequency accordingly (giving priority to buses if they’re running late, for example), which means that pressing the button has no effect.

According to Langer, a Harvard psychologist, placebo buttons give us the illusion (错觉)of control — and something to do in situations where the alternative would be doing nothing. In the case of pedestrian crossings, they may even make us safer by forcing us to pay attention to our surroundings. “They serve a psychological purpose at the very least,” she added.

1.Why are the physical buttons still kept in some cities?

A. Because it may cost money to replace them.

B. Because they remain as memories of a city.

C. Because do have real functions in traffic.

D. Because they can result in reliable lights.

2.Which of the following word can replace the underline word “features” in Paragraph 4?

A. Functions.

B. Uses.

C. Equipment.

D. Facilities.

3.If you pressed a “placebo button” in London, what would happen?

A. All traffic would be affected.

B. Some kind of sound might appear.

C. Pedestrians came first to cross the road.

D. “Green man” were bound to show up earlier.

4.What can we know about “palcebo buttons” from Langer’s words?

A. They can really control traffic.

B. They serve little functions.

C. They may work mentally.

D. They can help the blind.
