Foldable future has arrived

Tablets are really useful devices, but their big screens always make them as a burden to carry around without a bag. Wouldn’t it be great if there were a phone with the powers of a tablet that could be folded up and fit into the hand?

Now something like a tablet-shaped but foldable phone is about to show up. In February, South Korean electronics company Samsung and China’s Huawei both produced foldable phones, The Galaxy Fold and Huawei Mate X. Mobile phone use has entered the “foldable future”, The Verge said.

The technology could change our lives in meaningful ways. These devices, because of their bendable screens, give us the larger screens we want. Meanwhile, they still fit easily into the pocket.

The technology could change other devices too. For example, we could make TVs that stick to walls like posters, or fold up easily to hide away in drawers. In crowded modern cities, they will help us to make full use of space.

In a speech, Samsung’s senior vice president of mobile product marketing, Justin Denison, called the foldable screen “the base for the smartphone of tomorrow”. “It’s a white paper for us to do something beautiful together,” he said.

According to tech news website Android Authority, the necessary parts of foldable phones were difficult to produce. In 2012, nine out of every 10 OLED screens produced were not perfect. Today, that 10 percent rate has been improved to between 50 and 90 percent. However, at present these foldable devices are expensive. For example, the price of Huawei Mate X is 17,500 RMB. That’s a price that few people will be able to afford.

But if the foldable device isn’t going to change the world overnight, there is no doubt that it is coming. Patrick Moorhead, an industry analyst told The Verge, “Few are debating if foldable mobile screens are the future of smartphones; the only question is when and by whom.

Electrical devices (仪器) could soon use power made by human energy. Scientists say they have developed an experimental device that produces electricity from the physical movement of a person walking. British scientist Max Donelan and other scientists in Canada and the United States developed the device.

The device connects to a person's knee. As the person walks, the device captures energy each time the person slows down. To do this, the device helps with the slowing down movement of the leg. The movements of the walking person push parts of a small machine that produces electricity. Using the device, an adult walking quickly could produce thirteen watts of electricity in just a minute. Donelan says walking at that speed could produce enough power to operate a laptop computer for six minutes.

There are several possible uses for the device. Developers say it could help people who work in areas without electricity to operate small computers. The device could also be used in hospitals to operate heart pacemakers (起搏器). It could even be used to assist in the movement of robotic arms and legs.

The experimental version of the device weighs about one and a half kilograms, but it is too costly for most people to buy. But the researchers hope to make a lighter, less costly version. An improved version should be ready in one year.

The developers hope the device will one day help developing countries. Nearly twenty-five percent of people around the world live without electric power.

A similar product was invented in 2005 by Larry Rome of the University of Pennsylvania. He created a bag carried on a person's back that also produces power from walking. The knee device does not produce as much electricity as the bag. But the bag requires the walker to carry a load of twenty to thirty kilograms.

1.The second paragraph mainly talks about ________.

A. who developed the device

B. how the device works

C. several possible uses for the devices

D. how much electricity the device can produce

2.What is the disadvantage of the experimental version of the device?

A. It is too heavy for the walker to bear.

B. It is too complex for people to use.

C. It will slow down one's walking speed.

D. It is too expensive for most people to afford.

3.Compared with the device designed by Larry Rome, this new device ________.

A. produces power without adding more loads to the walker

B. can produce more power in a much shorter time

C. needs to be equipped with a battery

D. can help the walker walk faster

4.From the passage, we can learn that the electrical device can ________.

A. help housewives operate the micro-wave oven

B. make it much easier for us to go online

C. produce more electricity than that invented by Larry Rome

D. be applied in medicine to operate heart pacemakers

It has been showed that teachers in UK schools are trying the use of body cameras in class to record bad pupil's behavior.

At least two schools in England have introduced the equipment for constant recording with the agreement of local education authorities. The cameras, worn on teachers’ clothing, are set to film all the time but only save encrypted footage(加密镜头)when the record button is pressed, the Times reported.

Teachers are advised to turn on the cameras during incidents in the classroom to deal with “constant low-level interruption”, but must give notice before doing so.

The technology is already used by police and some hospital staff as well as crossing-patrol officers. Footage could also be shared with parents to involve them in addressing their children’s behavior. Feedback from parents and schools was said to be positive, with teachers praising them as an effective deterrent(震慑).

A survey published on Wednesday questioning teachers on the idea found more than a third would be willing to wear a body camera in the classroom, with many wanting the technology available to help fight with bad behavior from pupils.

Of the people who said they were in favor, about 31.6 percent said they were motivated by teacher and student safety. Among those who were not willing to use the technology, reasons included concerns about their own privacy and that of the children, as well as feeling spied on, or the possibility of misuse by management.

Around two-thirds of the teachers, more than 600 in total, said they feel safer in the classroom if they knew there was a camera recording everything, while 10.9 percent said they could foresee a time when bodycams are compulsory.

Mary Bousted, general secretary at the Association of Teachers and Lectures(ATL), said all schools should be safe places for pupils and staff.

1.If a teacher wants to save the record for later use, he should _____________.

A. give first notice

B. press the record button

C. film with the camera all the time

D. ask for the permission of the students

2.What can we learn from the text?

A. Some people agree with the idea.

B. None of the parents support the idea.

C. Students are not worried about their private things.

D. All schools have been safe about for teachers and students.

3.What may be the best title for the text?

A. The Use of Body Cameras in Class

B. Parents’ Reactions to Using Cameras

C. How to Record Students’ Good Behavior

D. The Advantages and Disadvantages of Taking Photos

Though cell-phones are usually considered devices that connect people, they may make users less socially minded, which is found by a recent study from the University of Maryland’s Robert H. Smith School of Business.

Marketing professors Anastasiya Pocheptsova and Rosellina Ferraro, with graduate student, Ajay T.Abraham, conducted a series of experiments on test groups of cellphone users. The findings appear in their working paper, The Effect of Mobile Phone Use on Prosocial Behavior. Prosocial behavior, as defined in their report, is action intended to benefit another person or society as a whole.

The researchers found that after a short period of cellphone use the subjects were less likely to volunteer for a community service activity, compared to the control-group（对照组）. The cell phone users were also less persistent in solving word problems even though they knew their answers would contribute to a monetary（货币的）donation to charity.

The study involved separate groups of college student subjects - both men and women and generally in their early 20s. "We would expect similar effects with people from other age groups," said Ferraro. "Considering the popularity of cellphones, it does have the potential to have wide social effects."

The researchers use previous research to explain the cause of their findings: "The cellphone directly arouses feelings of connection with others, thus fulfilling the basic social need to belong." This results in reducing one’s desire to connect with others face-to-face or to engage in empathic (同情的) and prosocial behavior.

The study also distinguished its subjects from users of other social media — Facebook users — in one of the tests. The researchers found that participants felt more connected to others because of their cell-phones than because of their Facebook accounts, suggesting that this difference in connectedness was the underlying cause of the observed phenomenon.

1.A person will conduct prosocial behavior when he ____.

A.is closely connected to his friends.

B.uses the cellphone for a period of time

C.takes part in community service

D.uses the cell phone a lot

2.What makes Facebook users different from cellphone users?

A.Different accounts.

B.Different purposes.

C.Different human needs.

D.The difference in connection.

3.Compared with cell phone users, Facebook users probably _____.

A.have a lot more friends

B.feel more connected to their friends

C.don’t like to engage in prosocial behavior at all

D.are more likely to engage in prosocial behavior

4.Which could be the best title for the passage?

A.Cell Phone Use Has Broad Social Effects

B.Cell Phone Use Leads to Prosocial behavior

C.Cell Phone Use Is Linked to Selfish Behavior

D.The Harmful Effect of Cell Phone Use

Future history books might record that we were robbed of the use of our eyes. In our hurry to get from one place to another, we fail to see anything on the way, Air travel gives you a bird’s eye view of the world ---or even less if the wing of the aircraft happens to get in your way. When you travel by car or train, you are moving so quickly that you do not see the countryside clearly. Car drivers are forever thinking about going on and on. They never want to stop. Is it the great motorways that attract them, or what? And as for sea travel, it hardly deserves mentioning. It is perfectly summed up in the words of the old song: “I joined the navy to see the world, and what did I see? I saw the sea.” You mention the place names in the world like EI Dorado, Kabul and someone is sure to say, “I have been there”, meaning I drove through it at 100 miles an hour on the way to somewhere else.

When you travel at high speeds, the present means nothing: you live mainly in the future because you spend most of your time looking forward to arriving at some other place. But actual arrival, when it is achieved, is meaningless. You want to move on again. By traveling like this, you suspend (中止) all experience; the present stops being a reality: you might just as well be dead.

The traveler on foot, on the other hand, lives constantly in the present. For him traveling and arriving are one and the same thing: he arrives somewhere with every step he makes. H e experiences, the present moment with his eyes, his ears and the whole of his body. At the end of his journey he feels a delicious physical tiredness. Satisfying sleep will be his: the just reward of all true travelers.

1.The underlined words “get in your way” in Paragraph I can be replaced, by ____.

A. block your sights

B. expand your range of vision

C. prevent you from going out of the plane halfway

D. make your travel continue

2.What does the author think of the travelers mentioned in Paragraph 1?

A. They get a good view of the landscape.

B. They make full use of their eyes.

C. They fail to see the scenery with their heart.

D. The y are eager to see everything on the way.

3.Why does “the present”mean “nothing ”when we travel at high speeds?

A. Because we change our aims all the time.

B. Because we are eager to go to another place.

C. Because we are looking forward to the future life.

D. Because we cannot enjoy the experience we have had.

4.What would be the best title for the passage?

A. Different travelers　　 B. The use of eyes

C. Ways of traveling　　 D. True traveling
