Sony has a new device for anyone who's ever wished they could carry their air conditioner on hot summer days.
Called Reon Pocket, the small, lightweight machine slides into the upper back pocket of a specially designed T-shirt. Controlled with a smart phone app, it's capable of heating or cooling the wearer via the Peltier effect, a thermodynamic (热力学) principle widely used in refrigeration.
The Reon Pocket comes out of Sony’ s startup acceleration program, and Sony is currently crowdfunding (众筹) the device. Supporters can choose from a few different packages, if they want multiple T-shirts for instance, but a basic one including the device and one shirt costs ￥14, 080. There's a catch, though: Sony only has plans to release the Reon Pocket in Japan at present.
The target audience is mostly businessmen who have to wear a suit in the summer, though the company says it will judge its wider relevance based on the crowdfunding results. Right now, though, the T-shirts available come in men's sizes, small, medium, or large.
The device is not really for all- day use so much as moving between air-conditioned or heated areas, such as travelling to work. The battery takes around two hours to charge and lasts about 90 minutes.
In a blog post from Sony's startup accelerator, Yoichi Ito, a project leader on Reon Pocket, said his team started thinking of ways to combine technology with fashion. Reon Pocket was the result. Japanese buyers looking to battle the record heat this summer will have to wait, though. If the crowdfunding is successful, deliveries of the device are scheduled to begin in July 2020.
1.Which of the following can be used to describe the new device?
A.Portable. B.Widely- used. C.Plain. D.Energy- saving.
2.What does the underlined word “packages” in Paragraph 3 refer to?
A.Sets of T-shirts. B.Sets of programs. C.Sets of services. D.Sets of items.
3.What can we infer about the new device from the passage?
A.Only businessmen can have free access to it. B.The fundraising affects its popularization.
C.Its special design makes it sell well in Japan. D.It can be rechargeable with a long life battery.
4.What's the author's purpose of writing the text?
A.To popularize modern conveniences. B.To combine technology and fashion.
C.To introduce a new electric device. D.To raise money for a good cause.

Anyone who has ever lost keys or money will have wished for a simple but effective way to make sure it never happens again. A US company is trying to help.
Using a tiny microchip which is implanted into the arm, they have come up with a replacement for cash or credit cards that cannot be left at home or dropped on the bus.
The Verichip is about the size of a grain of rice and works using radio frequency identification technology. At a shop, a radio frequency “reader” would send a signal and the chip in your arm would respond with your unique identity number. That would give the “reader” your financial information, and money could be taken directly from your accounts and you wouldn't even have to reach for your wallet.
The company also hopes to include other information on the chip, such as medical records, building security codes (密码) and passwords, making life even easier.
But not everyone is happy with the developments. Critics say that a lot can go wrong with the chip. A clever thief could build a fake (假的) reader that would steal your information without you knowing. So your money could still be stolen. Privacy is a big issue too. Stores, or even the government, only need to track the chip to find out what you buy, how much you spend and where you go.
And if you wanted to get rid of your chip, you would need an operation to remove it.
1.The Verichip is ________.
A．the identity number B．the security code
C．a tiny microchip D．a radio reader
2.Which is true of the Verichip?
A．Your information on it will always be safe.
B．Medical records have already been included.
C．You can easily reach for your wallet using it.
D．An operation has to be performed to remove it.

Have you ever been to the beautiful country of Holland and its capital Amsterdam? Anyone who has traveled to Amsterdam would probably agree on one thing: Amsterdam’s story is a tale of two cities—one during the day and a completely different one at night.
During the day, the largest city in Holland sits quietly on the Amstel River. You can rent a bicycle, visit the Van Gogh or Anne Frank museum, or take a water taxi. But when the sun goes down, the partying begins. In the big clubs and in coffee shops, tourists gather to hang out, talk politics and smoke.
Several areas of the city clearly show the two worlds that rule Amsterdam. And they’re all within a short taxi ride of each other. For example, Dam Square attracts daytime sightseers to its festivals, open markets, concerts and other events. Several beautiful and very popular hotels can be found there. And there’s the Royal Palace and the Magna Plaza shopping mall.
But at night party-seekers come to the square. Hip hop or funk music is heard there. So if you come, be ready to dance. The clubs don’t close down until 4 am.
And while you’re there, check out the various inexpensive ways to tour the city. Don’t worry about getting lost. Although Dutch is the official language, most people in Amsterdam speak English and are happy to help you with directions. And you’ll notice that half the people in the streets are on bicycles they rent.
Amsterdam also has a well-planned canal system. For about 10 dollars, you can use the canal bus or a water taxi to cruise (巡游) the "Venice of the North".
The city has a historic past. One impressive place to visit is the Anne Frank House on Nine Streets. It was there that the young Jewish girl wrote her famous diary during World War II. Visitors can view Anne’s original diary and climb behind the bookcase to the room where she and her family hid from the Nazis for two years.
59. The following means of transport are available to visitors in Amsterdam EXCEPT __________.
A. a carriage. B. a bicycle. C. a canal bus. D. a water taxi.
60. When getting lost, a visitor can ask natives for directions in .
A. only Dutch B. Dutch or English C. only English D. Spanish and English
61. What can you learn about by visiting the Anne Frank House?
A. The happy experience of a girl survivor. B. The glorious past of Amsterdam.
C. The hard life of the Jewish in World WarⅡ. D. The hobbies of the Dutch.
62. The passage is intended to .
A. call up people’s memories of World WarⅡ
B. tell readers what A Tale of Two Cities is about
C. instruct visitors what to do and see in Holland
D. offer readers some information about Amsterdam

Anyone who has ever played the game of Tetris (俄罗斯方块) knows the game’s surreal ability to spill into real life. After you shut off the game, you still see those Tetris blocks falling in your mind. You're grocery shopping and find yourself thinking about rearranging items on grocery shelves. Your mind continues to play the game, even when you're physically not.
Robert Stickgold, a Harvard professor, noticed something similar after a day hiking a mountain. That night, he dreamt he was still going through the motions of mountain hiking. Curious about this, he tried something: he got a group of college students of various skill levels to play Tetris and let them sleep in the Harvard sleep lab.
Over 60% of the students, including those who suffered from amnesia (健忘症), reported dreams of images of Tetris pieces falling, rotating (旋转), and fitting together. Interestingly, half the Tetris expert students reported such Tetris dreams, while 75% of the beginners did.
A study found that playing Tetris can grow your brain and make it more efficient. Adolescent girls played the game for an average of 1.5 hours a week over three months. The cerebral cortex (大脑皮层) of the girls grew thicker, while brain activity in other areas decreased. Richard Haier, who had found that there was a "Tetris learning effect", in which the brain consumed less energy as mastery of the game rose, concluded, "The brain is learning which areas not to use."
Haier's study showed that as the girls practiced playing the game, nerve cells made connections, communicating through synapses (a synapse is a connection between two nerve cells). When you learn something, you change those connections. Every time you reactivate(激活) a circuit, synaptic efficiency increases, and connections become more durable and easier to reactivate. Stickgold says sleep plays a role in this memory process.
So to sum up, whenever you do specific tasks over and over again, they take up less of your brain power over time. And that’s pretty amazing.
1.What does the underlined part ‘surreal ability’ in the first paragraph mean?
A. The game can help people arrange things in life.
B. The game can be applied to many aspects of life.
C. There are great similarities between the game and things in life.
D. The mind continues to play the game when we are doing other things.
2.What can we learn from Stickgold’s study?
A. More than half of the students dreamed of images of Tetris.
B. Students having bad memories didn’t dream of the game.
C. The Tetris expert students were more likely to dream of the game than the beginners.
D. More than half of the Tetris expert students didn’t dream of the game.
3.Playing Tetris for a long time can help ________.
①grow one’s brain
②one’s brain function efficiently
③arrange things tidily in life
④improve the adaptability of one’s brain
A. ①②③ B. ①②④
C. ②③④ D. ①③④
4.The purpose of the passage is to ________.
A. encourage people to play Tetris
B. warn people to focus while doing things
C. warn people not to play games before sleep
D. tell people they will improve at something if they keep doing it

COVID-19(新冠病毒) is a threat to the very people fighting it-nurses, doctors, and other first responders, who are exposed to infected patients. Now, a team has developed two devices(设备) that could reduce their risks by sucking away infectious bacteria: a helmet to be worn by a patient,and a small tent in which a patient could be protected. The inventors hope they'll reduce the deaths among healthcare workers.
Negative-pressure rooms have been used in hospitals since the 1980s to keep airborne bacteria from spreading.But Nathan Haas says such rooms cost about$12,000. He and his colleagues wanted to develop a cheaper way to create a negative pressure environment for patients.The new devices could lower the need for negative-pressure rooms,which are rare in many parts of the world,according to Haas.
The helmet can be used when staff transport patients and the tent can protect the upper body of a bed-bound patient wearing a mask,allowing staff to perform several procedures.
“They represent a really simple solution to potentially helping reduce virus spread and increase the safety of healthcare workers, as well as patient safety,” says Ben Bassin.
When the researchers tested their devices with a healthy volunteer,they saw 97% to 99%fewer bacteria outside the devices than inside.They also tested the devices' ease of use and comfort with seven COVID-19 patients.The response from patients and staff was good, Bassin says.
But Reuben Strayer notes the tests did not prove that these devices work to protect medical staff in real-life situations. He says he wants to see independent effect, “to see if they perform as they are advertised.”
1.The following statements are true EXCEPT
A.The devices are not complicated to use
B.People have already used the devices widely
C.The effect of the devices remains to be seen
D.Negative-pressure rooms are not common because of the high cost
2.What will most probably be discussed in the following paragraph?
A.The advantages of the devices. B.Different appearances of the devices.
C.Measures to put the devices into practice. D.The reasons for inventing the devices.
3.What is the author's purpose in writing the text?
A.To inform readers of the devices. B.To praise the efforts of the researchers.
C.To stress the importance of the devices. D.To encourage people to buy the devices.

Shortly before Christmas last year,Brazilian piano player Joao Carlos Martins invited his friends to a bar near his home. He wanted to show them the best gift he had received in many years:a new pair of gloves. They are not just any gloves,however. The specially made bionic(仿生）devices are letting the 79-year-old play with both hands for the first time in more than 20 years.
Martins 'health problems could be traced back to 1965. He suffered nerve damage in his arm from a soccer injury. And while he was on tour,a robber hit him over the head with a metal pipe in Bulgaria. Even his close friends believed that his career as a pianist would come to an end.
By his retirement last March,he had undergone 24 medical procedures to try to reduce pain caused by a series of accidents. As a result,he had been forced to work mostly as a musical conductor since the early 2000s.
However,one designer believed Martins 'retirement had come too early. That designer, Ubirata Bizarro Costa,created special bionic gloves for Martins 'hands. The gloves help move his fingers up after they press on the piano keys. Costa said he created early models based on images of Martins' hands,but that those models were“far from ideal”. He then decided to tell Martins about his efforts and they together spent several months testing different models. The perfect match came in December,and cost only$125 to build.
These days,Martins never takes off his new magic gloves-even when he goes to sleep. Martins said he had received more than 100 devices in the last 50 years as possible solutions to his hand problems. None worked well or long enough. "But these gloves do,"he said.
The new gloves have given Martins a new goal. He hopes to play the piano at New York's Carnegie Hall in October. He has already been preparing a concert celebrating the 60th anniversary of his first appearance there.
1.Which of the following is true about Joao Carlos Martins?
A.A designer who created special gloves for himself.
B.A musician who prefers conducting to playing the piano.
C.A pianist whose career was restricted by health problems.
D.A soccer lover who was hit over the head during a match.
2.What is special about Martins' s new gloves?
A.They have been around for a long time.
B.They are considered to be far from ideal.
C.They enable Martins to play with two hands.
D.They are developed mainly for the disabled.
3.In the process of creation,Costa did the following EXCEPT that
A.he perfected the gloves together with Martins.
B.he spent several months testing different models.
C.he made early models based on images of Martins 's hands.
D.he insisted on building the new gloves despite the high price.
4.What's the best title for the text?
A.Technology Improves People's Life
B.Martins Receives the Best Christmas Gift
C.Costa Creates the Special Gloves for Martins
D.Magic Gloves Let Brazilian Pianist Play Again

Anyone who has ever tried to stop smoking knows how difficult it is to quit. There is no lack of information about how unhealthy smoking is for you- not to mention the unpleasant smell. So why would teens ever begin to smoke?
1. Research shows that the majority of smokers lit up their first cigarette in their early or mid-teens, precisely at
a time when children are beginning to establish their own identity apart from their parents. Smoking can be an act of rebellion(反抗) against parents or authority figures, as well as a way to fit in with others and feel accepted.Here are some things that parents can do to help a child stay smoke-free.
Start talking to your teen about how bad smoking is for him early, well before his teens. Keep talking, too. 2.
3. For example, smoking makes your hair and clothing smell bad, stains the teeth, and reduces your lung power to play sports.
4. Talk about the addictive power of smoking and tell him while those few cigarettes are his choice, the addiction that occurs shortly afterwards makes him powerless to decide whether or not he wants to light up.
Work on self-esteem(自尊) and self-confident with your teen. Much of the attraction of smoking is to gain acceptance. 5.
Young teens live in the moment, too.
Play on your child’s desire to make his own choices.
The answer lies in the develop-mental stage of your teens.
Give your child the facts, but focus on the things he can relate to.
Help your teen to feel good about himself without having to smoke.
On
e discussion will not be enough to help your child not to smoke.They won’t be aware of how powerful addictive smoking is in a very short time.

Would you carry around an electronic ID, not in your pocket, but in your body? Does this idea scare you or make you feel safe?
The first computer ID chip(芯片) that could be planted under a person’s skin might be marketed very soon.
Developed by Applied Digital, an American technology company based in Florida, the device(发明物) could meet the need for public security(安全) after the September 11 attacks.
For airports, nuclear power plants(核电站) and other high security facilities, the immediate effects are obvious.
The technology could help put an end to false ID cards, because it would be difficult to remove and copy a tiny computer chip. The chip is as small as a grain of rice.
The technology would also allow satellites to track a person’s every movement and store medical records.
These uses are already attracting interest for tasks like fighting against kidnappings(绑架), or helping with medical operations.
But some people are afraid of the loss of privacy(隐私).
“You always have to think about what the device could be used for tomorrow,” said Lee Tien, a senior privacy lawyer in the United States.
“At first a device is used for applications we all agree are good, but then it slowly starts being used for more than it was intended,” he said.
However, Applied Digital says it will soon apply for government permission for the device. It says that the first people to use the chip will be volunteers.
Getting the implant(需移植的芯片) would go something like this:
A person or company buys the chip from Applied Digital for about US $ 200. And the company encodes(编码) it with the desired information.
The customer then takes the chip to their doctor, who can plant it with a large needle.
The device has no power supply, rather it is activated(使活动, 使运行) by a scanner(扫描仪) running across the skin above it. Without a scanner, the chip cannot be read.
Even with the privacy concern, some are already eager to use the product.
Jell Jacobs from Florida hopes to become the first buyer of the chip to store his medical records. Suffering from a serious illness, he wants to make sure doctors can help him quickly.
Eight Latin American companies have also shown interests in the device. It could help to find any tourists who are kidnapped.
1.The best title for the passage is _______.
A.Why Is the New ID Necessary B.Getting a New Kind of ID Under Your Skin
C.An Advertisement for Chips D.Where to Buy the Chip
2.Which of the following is true according to the text?
A.In some airports and factories such device is already being used.
B.The information on the chip can be read when it has its power supply.
C.The technology could help put an end to false ID cards.
D.The first computer ID chip has already come into the market.
3.What is the advantage with the electronic ID according to the passage?
A.It can store people’s medical records and help with medical operations.
B.With this people will have no fear of losing privacy.
C.It’s cheap to buy and easy to get.
D.It is developed by Applied Digital in Florida.
4.What can we learn about Jeff Jacobs?
A.He’s a worker in Applied Digital, a company in Florida.
B.He’s a doctor who helps plant tile chips on people.
C.He fears if he uses the chip he will lose privacy.
D.He’s suffering from a serious illness and wants to buy the chip.
