1 . As data and identity theft becomes more and more common, the market is growing for biometric(生物测量) technologies—like fingerprint scans—to keep others out of private e-spaces. At present, these technologies are still expensive, though.

Researchers from Georgia Tech say that they have come up with a low-cost device(装置) that gets around this problem: a smart keyboard. This smart keyboard precisely measures the cadence(节奏) with which one types and the pressure fingers apply to each key. The keyboard could offer a strong layer of security by analyzing things like the force of a user’s typing and the time between key presses. These patterns are unique to each person. Thus, the keyboard can determine people’s identities, and by extension, whether they should be given access to the computer it’s connected to—regardless of whether someone gets the password right.

It also doesn’t require a new type of technology that people aren’t already familiar with. Everybody uses a keyboard and everybody types differently.

In a study describing the technology, the researchers had 100 volunteers type the word “touch” four times using the smart keyboard. Data collected from the device could be used to recognize different participants based on how they typed, with very low error rates. The researchers say that the keyboard should be pretty straightforward to commercialize and is mostly made of inexpensive, plastic-like parts. The team hopes to make it to market in the near future.

2 . With the young unable to afford to leave home and the old at risk of isolation(孤独), more families are choosing to live together.

The doorway to peace and quiet, for Nick Bright at least, leads straight to his mother-in-law, she lives on the ground floor, while he lives upstairs with his wife and their two daughters.

Four years ago they all moved into a three-storey Victorian house in Bristol - one of a growing number of multigenerational families in the UK living together under the same roof. They share a front door and a washing machine, but Rita Whitehead has her own kitchen, bathroom, bedroom and living room on the ground floor.

“We floated the idea to my mum of sharing at a house,” says Kathryn Whitehead. Rita cuts in: “We spoke more with Nick because I think it’s a big thing for Nick to live with his mother-in-law.”

And what does Nick think? “From my standpoint, it all seems to work very well. Would I recommend it? Yes, I think I would.”

It’s hard to tell exactly how many people agree with him, but research indicates that the numbers have been rising for some time. Official reports suggest that the number of households with three generations living together had risen from 325,000 in 2001to 419,000 in 2013.

Other varieties of multigenerational family are more common. Some people live with their elderly parents; many more adult children are returning to the family home, if they ever left. It is said that about 20% of 25-34-year-olds live with their parents, compared with 16% in 1991.The total number of all multigenerational households in Britain is thought to be about 1.8 million.

Stories like that are more common in parts of the world where multigenerational living is more firmly rooted. In India, particularly outside cities, young women are expected to move in with their husband’s family when they get married.

1. Who mainly uses the ground floor in the Victorian house in Bristol?

A．Nick.

B．Rita.

C．Kathryn

D．The daughters.

2. What is Nick’s attitude towards sharing the house with his mother-in -law?

D．Public opinions.

4. What is the text mainly about?

A．Lifestyles in different countries.	B．Conflicts between generations.

3 . We’ve all been there: in a lift, in line at the bank or on an airplane, surrounded by people who are, like us, deeply focused on their smartphones or, worse, struggling with the uncomfortable silence.

What’s the problem? It’s possible that we all have compromised conversational intelligence. It’s more likely that none of us start a conversation because it’s awkward and challenging, or we think it’s annoying and unnecessary. But the next time you find yourself among strangers, consider that small talk is worth the trouble. Experts say it’s an invaluable social practice that results in big benefits.

Dismissing small talk as unimportant is easy, but we can’t forget that deep relationships wouldn’t

even exist if it weren’t for casual conversation. Small talk is the grease(润滑剂) for social communication, says Bernardo Carducci, director of the Shyness Research Institute at Indiana University Southeast. ＂Almost every great love story and each big business deal begins with small talk,＂ he explains. ＂The key to successful small talk is learning how to connect with others, not just communicate with them.＂

In a 2014 study, Elizabeth Dunn, associate professor of psychology at UBC, invited people on their way into a coffee shop. One group was asked to seek out an interaction(互动) with its waiter; the other, to speak only when necessary. The results showed that those who chatted with their server reported significantly higher positive feelings and a better coffee shop experience. ＂It’s not that talking to the waiter is better than talking to your husband,＂ says Dunn. ＂But interactions with peripheral(边缘的) members of our social network matter for our well-being also.＂

Dunn believes that people who reach out to strangers feel a significantly greater sense of belonging, a bond with others. Carducci believes developing such a sense of belonging starts with small talk. ＂Small talk is the basis of good manners,＂ he says.

1. What phenomenon is described in the first paragraph?

A．Addiction to smartphones.

B．Inappropriate behaviours in public places.

C．Absence of communication between strangers.

D．Impatience with slow service.

2. What is important for successful small talk according to Carducci?

A．Showing good manners.	B．Relating to other people.
C．Focusing on a topic.	D．Making business deals.

3. What does the coffee-shop study suggest about small talk?

A．It improves family relationships.	B．It raises people’s confidence.
C．It matters as much as a formal talk.	D．It makes people feel good.

4. What is the best title for the text?

A．Conversation Counts	B．Ways of Making Small Talk
C．Benefits of Small Talk	D．Uncomfortable Silence

4 . 阅读下面材料,在空白处填入适当的内容(1个单词)或括号内单词的正确形式。

Something significant is happening to the world population-it is aging. The median(中位数的)age of an American in 1950    1    (be)30-today it is 41 and is expected    2    (increase)to 42 by 2050. For Japan, the    3    (number)are more striking-22 in 1950, 46 today and 53 in 2050. In 2015, one in 12 people around the world were over 65；by 2050, it will be one in six.

This aging of the population is driven    4    two factors. The first is declining birthrates, which means old generations are large    5    (compare)to younger generations, and so, on average, the population becomes    6    (old)than before. This is    7    (particular)true in the US. The second reason is that people are living longer. A child born in the US today has    8    very realistic chance of living beyond 100 and needs to plan accordingly.

People tend to focus on the first factor. However, greater attention should    9    (place)on longevity(长寿). It isn't just that people are, on average, living longer. It's also that they are on average healthier    10    more productive for longer. Therefore, they can work for longer, consume more and in general be a boost to the economy.

5 . 阅读下面材料，在空白处填入适当的内容（1个单词）或括号内单词的正确形式。

Few people I know seem to have much desire or time to cook. Making Chinese     1    (dish) is seen as especially troublesome. Many westerners     2     come to China cook much less than in their own countries once they realize how cheap     3     can be to eat out. I still remember     4     (visit) a friend who’d lived here for five years and I     5    (shock) when I learnt she hadn’t cooked once in all that time.

While regularly eating out seems to     6    (become) common for many young people in recent years, it’s not without a cost. The obvious one is money; eating out once or twice a week may be     7    (afford) but doing this most days adds up. There could be an even     8     (high) cost on your health. Researchers have found that there is a direct link between the increase in food eaten outside the home and the rise in     9    (weigh) problems.

If you are not going to suffer this problem, then I suggest that the next time you go to your mum’s home     10     dinner, get a few cooking tips from her. Cooking food can be fun. You might also begin to notice the effects not only on your health but in your pocket.

6 . Who cares if people think wrongly that the internet has had more important influences than the washing machine? Why does it matter that people are more impressed by the most recent changes?

It would not matter if these misjudgments were just a matter of people’s opinions. However, they have real impacts, as they result in misguided use of scarce resources.

The fascination with the ICT(Information and Communication Technology) revolution, represented by the internet, has made some rich countries wrongly conclude that making things is so “yesterday” that they should try to live on ideas. This belief in “post-industrial society” has led those countries to neglect their manufacturing sector(制造业), with negative consequences for their economies.

Even more worryingly, the fascination with the internet by people in rich countries has moved the international community to worry about the “digital divide” between the rich countries and the poor countries. This has led companies and individuals to donate money to developing countries to buy computer equipment and internet facilities. The question, however, is whether this is what the developing countries need the most. Perhaps giving money for those less fashionable things such as digging wells, extending electricity networks and making more affordable washing machines would have improved people’s lives more than giving every child a laptop computer or setting up internet centres in rural villages, I am not saying that those things are necessarily more important, but many donators have rushed into fancy programmes without carefully assessing the relative long-term costs and benefits of alternative uses of their money.

In yet another example, a fascination with the new has led people to believe that the recent changes in the technologies of communications and transportation are so revolutionary that now we live in a “borderless world”. As a result, in the last twenty years or so, many people have come to believe that whatever change is happening today is the result of great technological progress, going against which will be like trying to turn the clock back. Believing in such a world, many governments have put an end to some of the very necessary regulations on cross-border flows of capital, labour and goods, with poor results.

Understanding technological trends is very important for correctly designing economic policies, both at the national and the international levels, and for making the right career choices at the individual level. However, our fascination with the latest, and our under valuation of what has already become common, can, and has, led us in all sorts of wrong directions.

1. Misjudgments on the influences of new technology can lead to ________.

A．a lack of confidence in technology

B．a slow progress in technology

A．Neglecting the impacts of technological advances.

B．Believing that the world has become borderless.

C．Ignoring the power of economic development.

D．Over-emphasizing the role of international communication.

4. What can we learn from the passage?

A．People should be encouraged to make more donations.

B．Traditional technology still has a place nowadays.

C．Making right career choices is crucial to personal success.

D．Economic policies should follow technological trends.

7 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Up to 82 percent of children with healthy mothers are not easy to be obese（肥胖的）, according to research. A mother,     1     has a healthy weight, exercises regularly, eats a healthy diet, doesn’t smoke and only     2    (drink) wine in moderation, is significantly less likely     3    (have)a fat child, scientists say.

And research suggests it could be more to do with nurture(养育)    4     nature, as a mother's lifestyle appears     5    (direct) linked to the health of her child. When both mother and child follow a healthy lifestyle, the risk of obesity     6    (reduce)even more, the study of more than 24,000 children found.

The study examined the medical history and lifestyles of more than 24,000 children aged nine     7     fourteen, born to almost 17,000 women in the US. Researchers looked at the link between overall mother health and likelihood of a child     8    (be) obese.

The mother's health was judged on her height-to-weight ratio(比例), her diet, amount of physical     9    (active), smoking status and how much alcohol she drank. A healthy weight and diet, regular exercise, no smoking and moderate drinking all reduce the chance of a woman having     10     obese child.

You must have heard about Dolly and have been amazed by the first cloned animal. But here came a problem; should we clone humans? When being asked about this question, a large number of people which are interested in the topic hold the view that it’s beneficial to clone humans. Therefore, some other people, me including, are against this idea. Cloning humans can bring negative effects and wrong informations. In the first place, they may not be treated equal as normal people, which I believe will make him suffer a lot. In second place, human cloning may lead in some social disorder, and it is quite dangerous.

9 . Grandparents Answer a Call

As a third－generation native of Brownsville, Texas, Mildred Garza never planned to move away.Even when her daughter and son asked her to move to San Antonio to help with their children, she politely refused.Only after a year of friendly discussion did Ms.Garza finally say yes.That was four years ago.Today all three generations regard the move as a success, giving them a closer relationship than they would have had in separate cities.

No statistics show the number of grandparents like Garza who are moving closer to adult children and grandchildren. Yet there is evidence suggesting that the trend is growing.Even President Obama’s mother-in-law, Marian Robinson, has agreed to leave Chicago and move into the White House to help care for her granddaughters. According to a study by grandparents.com, 83 percent of the people said Mrs.Robinson's decision will influence grandparents in the American family.Two－thirds believe more families will follow the example of Obama’s family.

“In the 1960s we were all a little wild and couldn't get away from home far enough or fast enough to prove we could do it on our own,”says Christine Crosby, publisher of Grand, a magazine for grandparents. “We now realize how important family is and how important it is to be near them, especially when you’re raising children.”

Moving is not for everyone. Almost every grandparent wants to be with his or her grandchildren and is willing to make sacrifices, but sometimes it is wiser to say no and visit frequently instead.Having your grandchildren far away is hard, especially knowing your adult child is struggling, but giving up the life you know may be harder.

1. Why was Garza’s move a success?

A．It strengthened her family ties.

B．It improved her living conditions.

C．It enabled her to make more friends.

D．It helped her know more new places.

2. What was the reaction of the public to Mrs.Robinson’s decision?

A．17% expressed their support for it.

B．Few people responded sympathetically.

C．83% believed it had a bad influence.

D．The majority thought it was a trend.

3. What did Crosby say about people in the 1960s?

A．They were unsure of themselves.

B．They were eager to raise more children.

C．They wanted to live away from their parents.

D．They had little respect for their grandparents.

4. What does the author suggest the grandparents do in the last paragraph?

A．Make decisions in the best interests of their own.

B．Ask their children to pay more visits to them.

C．Sacrifice for their struggling children.

D．Get to know themselves better.

10 . In recent years, China has witnessed the growth of luxury (奢侈品) brands. In this market, Chinese consumers are now the largest spenders. It’s clear that a new generation of young, materialistic people is increasingly relying on luxury brands to improve its self-image. I am a fashionist too, at least in spirit — I love to look at clothes and shoes. But I don’t understand why people spend lots of money on designer labels. When a young woman buys a handbag that costs two months of her salary, that’s a scary thing.

What’s interesting is that scientists have found that having luxury things doesn’t lead to happiness. Study after study has shown that although we want material things, when we get them we don’t suddenly become “happy” people. In fact, a series of studies by Leaf Van Boven at the University of Colorado, US, has shown that individuals who spend money on travel and similar experiences get more pleasure than those who invest it in material things. That’s because experiences are more easily combined with a person’s identity. If I travel to Yunnan, that adventure affects how I think in the future. My memories become a part of me.

Moreover, as Van Boven has observed, young people who pursue happiness through “things” are liked less by their peers. People prefer those who pursue happiness through experiences.

It’s natural to want to express yourself through your appearance. So my advice is: create a look that isn’t tied to a designer label. Convey your own message. Take some lessons from the late Apple co-founder Steve Jobs. He was always in Levis jeans and a black turtleneck. Mark Zuckerberg, founder of Facebook, routinely appears in hoodies and sneakers. These people, successful people, have style. You don’t have to break the bank to send a message about who you are. Take a trip. Go out into the world. Then come back and confidently create your own signature look.

1. What can we infer from the first paragraph?

A．The author enjoys buying luxury brands herself.

B．The author agrees to overspend money on material things.

C．The author is critical of youths tying their looks to designer labels.

D．The author finds it natural for fashionists to follow fashion trends.

2. Leaf Van Boven’s studies showed that ______.

A．people dislike those who love luxuries

B．traveling changes a person’s identity greatly

C．luxuries have a negative effect on people’s happiness

D．experiences can bring people more happiness than luxuries

3. What is the author’s advice on expressing oneself?

A．Be selective about designer labels.	B．Create your own personal unique style.
C．Choose simple and fashionable styles.	D．Try styles like Mark Zuckerberg’s.

4. The main purpose of the article is to ______.

A．prove how luxury leads to an unpleasant life

B．tell how to express yourself through appearances

C．report on a series of studies about luxuries and happiness

D．persuade readers to invest in experiences instead of luxuries
