Teenagers who talk on the cell phone a lot, and hold their phones up to their right ears, score worse on one type of memory test. That’s the finding of a new study. That memory impairment might be one side effect of the radiation (放射线) that phones use to keep us connected while we’re on the go.
Nearly 700 Swiss teens took part in a test of figural memory. This type helps us remember abstract (抽象的) symbols and shapes, explains Milena Foerster. The teens took memory tests twice, one year apart. Each time, they had one minute to remember 13 pairs of abstract shapes. Then they were shown one item from each pair and asked to match it with one of the five choices. The study volunteers also took a test of verbal memory. That’s the ability to remember words. The two memory tests are part of an intelligence test. The researchers also surveyed the teens on how they use cell phones. And they got call records from phone companies. The researchers used those records to figure out how long the teens were using their phones. This allowed the researchers to work out how big a radiation exposure (接触) each person could have got while talking.
A phone user’s exposure to the radiation can differ widely. Some teens talk on their phones more than others. People also hold their phones differently. If the phone is close to the ear, more radiation may enter the body, Foerster notes. Even the type of network signal that a phone uses can matter. Much of Switzerland was using an older “second-generation” type of cell phone networks, the study reports. Many phone carriers (通讯公司) have moved away from such networks. And more companies plan to update their networks within the next few years.
The teens’ scores in the figural memory tests were roughly the same from one year to the next. But those who normally held their phones near the right ears, and who were also exposed to higher levels of radiation, scored a little bit worse after a year. No group of teens showed big changes on the verbal memory test. Why might one type of memory be linked to cell phone use, but not another? Foerster thinks it could have to do with where different memory centers sit in the brain. The site that deals with the ability to remember shapes is near the right ear.

America is a mobile society. Friendships between Americans can be close and real, yet disappear soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while—then no more. If the same two people meet again by chance, even years later, they pick up the friendship. This can be quite difficult for us Chinese to understand, because friendships between us flower more slowly but then may become lifelong feelings, extending (延伸) sometimes deeply into both families.
Americans are ready to receive us foreigners at their homes, share their holidays, and their home life. They will enjoy welcoming us and be pleased if we accept their hospitality (好客) easily, but truly can’t manage the time to do a great deal with a visitor outside their daily routine. They will probably expect us to get ourselves from the airport to our own hotel by bus. And they expect that we will phone them from there. Once we arrive at their homes, the welcome will be full, warm and real. We will find ourselves treated hospitably.
Another difficult point for us Chinese to understand Americans is that although they include us warmly in their personal everyday lives, they don’t show their politeness to us if it requires a great deal of time. This is usually the opposite of the practice in our country where we may be generous with our time. Sometimes, we, as hosts, will appear at airports even in the middle of the night to meet a friend. We may take days off to act as guides to our foreign friends. The Americans, however, express their welcome usually at homes,
For the Americans, it is often considered more friendly to invite a friend to their homes than to go to restaurants, except for pure business matters. So accept their hospitality at home !
1.Where are we expected to call our American friends if we go there by plane?
A.On the bus. B.At the airport.
C.Near their home. D.At our own hotel.
2.Which of the following statements is TRUE according to the passage?
A.Friendships between Americans usually last for all their lives.
B.Americans always show their warmth even if they are very busy.
C.Americans will continue their friendships again even after a long break.
D.Friendships between Americans usually extend deeply into their families.
3.Which is the typical way of American hospitality?
A.Treating friends at home. B.Sharing everything they have.
C.Taking days off to be with friends. D.Meeting friends at the airport at midnight.
4.In which part of a newspaper can this article be found?
A.Culture. B.News.
C.Story. D.Travel.
Albert Einstein, the genius behind the theory of relativity, which provided a new framework for all of physics and proposed new concepts of space and time, has recently been making headlines again. However, this time it is not for a new scientific breakthrough, but because of two handwritten notes the scientist gave a bellboy 95 years ago.
The story goes something like this. In October 1922, Einstein was invited to Tokyo to deliver lectures. As the scientist was making his way from Europe to Japan, he received a telegram informing him that he had been awarded the Nobel Prize in Physics. Though pleased at the news, he decided to continue with his Japanese trip instead of heading to Stockholm to accept the honor.
When in Tokyo, he penned two notes in German. One of them, written on a piece of plain paper, said, “Where there’s a will, there’s a way.”
Why did Einstein write the notes? Some believe they were to express Einstein’s delight at the reception he received from the people of Japan who crowded to attend the laureate’s (获奖者)lectures. Others think they were specially written for a bellboy who came to deliver a message, either because the scientist did not have loose change to tip him, or because the messenger refused to accept tips. Regardless of the reason, Einstein purportedly told the bellboy, “Maybe if you are lucky, those notes will become much more valuable than just a regular tip.” He was right!
Earlier this year, the bellboy’s nephew decided to part with the letters and handed them to Winner’s Auctions and Exhibitions. The “theory of happiness” brought the owner an astonishing $1.56 million from a European buyer. The second note, which opened at $1,000, and expected to fetch a maximum of $6,000, sold for $240,000!
1.What made Einstein become people’s focus again?
A.The theory of relativity. B.His new concepts of space.
C.The notes written by himself. D.His notes about his theory.
2.Where did Einstein write the words?
A.Bern. B.Stockholm.
C.Germany. D.Japan.
3.How were Einstein’s lectures?
A.They had a great effect. B.They attracted a lot of people.
C.They successfully inspired people. D.They were hard to understand.
4.How might the owner of the notes feel about the deal?
A.Disappointed. B.Curious.
C.Unfair. D.Unexpected.

Cloud tourism “refers to a new, non-contact immersive(沉浸式的)sight-seeing experience that depends on advanced technology, like live streaming.5G technology and virtual reality.
It has enjoyed great popularity in China recently. A 65-year old man said: “I visited Dunhuang on WeChat on May 1.” “I had never experienced a travel without getting out there like that. It is quite convenient, and I can learn a lot in the flower show, because there are vivid photos and detailed explanations,” a young office employee said.
However, many argue that “cloud tourism” is not tourism at all. Here are some comments.
Li Ming: “It is more of a documentary ,and I could not enjoy myself.”
Ma Dong: “I don’t want to travel on the phone. I would rather travel with my family and friends.”

Coupons-good way to boost consumption
In an effort to boost consumption and counter some the of the negative impacts of the novel coronavirus outbreak on the economy,authorities in more than 30 cities have distributed consumption coupons(优惠券)among local residents.Given that a better part of China’s economy is now mainly driven by domestic consumption,issuing consumption coupons should be seen as an ingenious way to help stabilize the economy.
The outbreak has sharply reduced consumption in the tourism,retail,catering,”cultural and entertainment industries in the first three months of this year,increasing the risk of unemployment.As for the impact of the outbreak for the entire year,it depends on whether consumption in the coming months would make up for the decline of consumption in the first quarter,in particular,the Spring Festival period.
The expected increase in consumption, especially in the durable goods sector, after the outbreak is effectively contained could partly balance out previous losses. But still it would be impossible to see a consumption spree(消费热潮)similar to that during Spring Festival.
Rising exports could possibly make up for the decline in domestic consumption.But net exports are not likely to rise this year because many countries have shut down their airports and seaports,and locked down cities to prevent the spread of the virus.
As such,the authorities have to boost consumption using whatever means.And as consumption is influenced by three factors-people’s income,confidence,and price of goods and services-the authorities should first reduce the epidemic’s negative impact on people’s income,by ensuring they have enough money spend.Second,they should boost people’s confidence so they dare to spend more.And third,the authorities should stabilize prices to encourage people to increase consumption.
Consumption coupons are a good way to achieve all the three goals. Issuing consumption coupons is similar to increasing people’s income and promoting consumption, because the coupons can be used to buy goods and services.
Many local authorities have even issued electronic consumption coupons through third-party payment. Such coupons are highly efficient,convenient,and easy to track.And since they also ensure equality and fairness,they are a good example of the important role digitalization plays in China’s social and economic governance.
The consumption coupons the local authorities have issued until now are mainly to boost the catering industry,obviously because the outbreak has dealt the industry a big blow.But the authorities should consider broadening the scope of the coupons in the future to further increase consumption by,say,issuing coupons that can be used in more sectors,including those for buying home appliances.
Moreover,the authorities could also combine e-coupons with targeted printout coupons for impoverished groups,extend the validity period for the coupons.But in general,the consumption coupons will play an active role in boosting domestic consumption this year.
