Ray Kurzweil is an inventor and futurist with some interesting ideas on how humans will soon be able to live much longer than the average 78 years they do now. If Kurzweil is right, this is a question we’ll have to ask ourselves in the near future.
The first challenge is how to stop our bodies from getting old and dying. Kurzweil doesn’t see this as a problem. With gene technology we’ll soon be able to “turn off” genes that cause ageing and disease. This technology is getting cheaper and advancing at an incredible rate. Kurzweil believes that from every year after 2023, we’ll be adding more than a year to the average life expectancy. He also expects that within the next 20 years, we will have ‘nanobots’ in our blood. These tiny robots will automatically keep our bodies healthy and free from diseases by finding damaged cells and destroying them.
Of course, if we’re all going to live longer, then there are going to be more of us on this already overcrowded Earth. Many people think there are likely to be problems with resources such as food and energy. Kurzweil doesn’t agree. He says that the same technologies used to increase our life expectancy will also be used to help with food production and energy needs. For example, he says, sunlight can potentially give us 10,000 times more energy than we currently use. We just need to develop the technology to capture it and make it cheaper. There are also new technologies that can recycle water extremely cheaply. This means that dirty water can be made clean again at a very low cost. When you consider that 80% of disease in the developing world is because of dirty water, you can see how this technology might help change the world.
But what are we going to do with all this extra time? Won’t we all get bored? Again Kurzweil says ‘no’. For a start, we won’t be stuck in old bodies. We’ll stay young for years. This will mean we’ll be able to experiment with many more things than we can now. We’ll also see huge developments in virtual reality technology that will keep us entertained for years.
The future according to Ray Kurzweil looks good — and we might just be around to see it.

However, watchmakers optimistically say that watches redeem(挽回) popularity when consumers reach their 20s and 30s. By then, they are willing to spend money on a quality watch that doesn’t just keep good time. Fifty years ago, watchmakers took pride in their products’ accuracy. But in recent years, the watch industry has changed itself into an accessory(配饰) business. And today, the image a watch conveys has become more important than the time it tells.
“Complications” — features that go beyond simple timekeeping — are an important part of a watch’s image. Today’s watches offer lots of features that meet almost any personality. These features include compasses, USB drivers, and even other functions that measure the effectiveness of golf swings!
Creativity also plays a key role in designing today’s watches. For example, Japanese watchmaker Tokyoflash makes watches that don’t even look like watches. The company’s popular Shinshoku model uses different color lights to tell time. It looks more like a fashionable bracelet(手镯) than a watch.
Whether a watch conveys fashion sense, creative talent or a love of sports, consumers want their watches to stand out. Nowadays, everyone has the same kind of little things in their bags, so people want to make a statement with what’s on their wrists. Will this interest in wrist fashion last? Only time will tell!
1. What can we know from the first paragraph?
A.As most people see, watches are out of fashion. |
B.Some people feel that watches have been of no use. |
C.The watch industry will close down sooner or later. |
D.There are so many choices of watches for teenagers today. |
A.It simply tells time. |
B.It appeals to many teenagers. |
C.It has many complex functions. |
D.It has an impact on creativity and imagination. |
A.show why Shinshoku watches are popular |
B.advertise Shinshoku watches made by Tokyoflash |
C.make a comparison between watches and bracelets |
D.tell that today’s watches need more imagination |
A.Watches Tell More Than Time |
B.Japanese Watches Stand Out |
C.Watch Industry Is in a Bad Situation |
D.Watches Are Becoming Less Popular |
【推荐3】In 2006, an alarm sounded concerning the health of honeybees in the United States when a Florida beekeeper found 400 of his hives were empty.
Food. Grow a variety of plants to supply nectar (花蜜) and pollen (花粉) throughout the growing season. Bees like plants native to their habitats.
Water. Although we rarely see them taking a drink, bees appreciate gardens with a source of water. It can be as simple as filling a shallow water dish with small stones and branches so bees can land and rest while drinking. A birdbath (水盘) also offers a dependable destination for bees.
Shelter.
By creating an environment with shelter, water, and bee-friendly plants, soon your local bees will be buzzing.
A.Replace the water regularly. |
B.Even plants in a window box can help. |
C.Leave an inch of space between holes. |

【推荐1】We are encountering real-world examples of how AI can harm human relations. As digital assistants such as Alexa or Siri become popular, we become accustomed to talking to them as though they were alive. Writing in these pages several years ago, Judith Shulevitz described how some of us are starting to treat them as friends and therapists. Shulevitz herself says she confesses (忏悔) things to Google Assistant that she wouldn’t tell her husband. If we grow more comfortable talking to our devices about our secrets, what happens to our human marriages and friendships? Designers and programmers typically create devices whose responses make us feel better — but may not help us be self-reflective or think over painful truths. As AI goes deeper into our lives, we must face the possibility that it will prevent our emotions and deep human connects.
Besides, we will fight with some other challenges. The age of driverless cars, after all, is upon us. These vehicles promise to considerably reduce the exhaustion and distraction that put human drivers in danger, thus preventing accidents. But what other effects might they have on people? Driving is a very modern kind of social interaction, requiring high levels of cooperation. I worry that driverless cars, by taking away from us an occasion to exercise this ability, could contribute to its decline.
Not only will these vehicles be programmed to take over driving duties and hence to remove from humans the power to make moral judgments (for example, about which pedestrian to hit when a crash is unavoidable), they will also affect humans with whom they’ve had no direct contact. For instance, drivers who have steered awhile alongside an autonomous vehicle traveling at a steady, changeless speed might drive less attentively, thus increasing their likelihood of accidents once they’ve moved to a part of the highway occupied only by human drivers. Alternatively, experience may reveal that driving alongside autonomous vehicles travelling in perfect accordance with (按照) traffic laws actually improves human performance.
Either way, we should be careful to launch new forms of AI without first taking such unexpected social effects into account. We must apply the same effort that we apply to the hardware and software that make self-driving cars possible to managing AI’s potential effects on those outside the car. After all, we install brake lights on the back of your car not just, or even primarily, for your benefit, but for the sake of the people behind you.

【推荐2】Last month, Justin Valdez, a college student, was shot in a subway station in San Francisco. The surveillance video(监控录像) showed that before Justin was killed, the killer pulled out his gun several times, and even wiped his nose with it. However, nobody noticed the killer. The surrounding passengers all focused on their cell phones.
We may see the same scene everywhere in our life: in subway stations, restaurants, elevators and so on, people are watching their cell phones. From a family reunion to a date with a friend, people couldn’t stop checking their twitter and facebook on the cell phones and ignoring the persons in front completely, Phubbing(低头症) not only involves young people, but also the elderly and kids.
“Phubbing” is a new term which comes from the words“phone” and “snub”(冷落). It describes the habit of snubbing someone in favor of a cell phone. The word “phubbing” was included in the Australian National Dictionary in 2012. Obviously, the indifference (冷漠) and rudeness of the information age are spreading globally.
A Stop Phubbing campaign website has been set up. You can find the slogan of the website as follows: “stop twittering, stop posting photos…enjoy your food, enjoy the music and respect others.”
Phubbing appears harmless. However, it does influence our life. Jimmy, an epicure(美食家), wrote in his blog: “I can no longer focus on what I am eating since I started twittering. My skill of food photography has improved very fast, while my interest in food drops as a result.” Let us put down our cell phones and re-enjoy the real taste of our food and the warmth of interpersonal communication.

【推荐3】Young children are significantly more likely than adults to have their opinions influenced by robots, according to a new research. The study, conducted at the University of Plymouth, compared how adults and children respond to an identical task when in the presence of both their peers (同龄人) and robots.
It showed that while adults regularly have their opinions influenced by peers, something also demonstrated in previous studies, they are largely able to resist(抵制) being persuaded by robots. However, children aged between seven and nine were more likely to give the same responses as the robots, even if they were obviously incorrect.
The study asks people to look at a screen showing four lines and say which two match in length. When alone, people almost never make a mistake but when doing the experiment with others, they tend to follow what others are saying.
When children were alone in the room in this research, they scored 87% on the test, but when the robots join in their score drops to 75%. And of the wrong answers, 74% matched those of the robot.
Professor Belpaeme said, “People often follow the opinions of others and we’ve known for a long time that it is hard to resist taking over views and opinions of people around us. But as robots will soon be found in the home and the workplace, we were wondering if people would follow robots.”
“What our results show is that adults do not follow what the robots are saying. But when we did the experiment with children, they did. It shows children can perhaps have more of an affinity (亲和力) with robots than adults, which does pose the question: What if robots were to suggest, for example, what products to buy or what to think?”
1. What did the adults do when staying with robots?A.They totally accepted the robots’ suggestions. |
B.They tried to persuade robots to resist them. |
C.They generally refused the robots’ effects. |

A.Because robots in the presence made mistakes. |
B.Because children were not as clever as the adults. |
C.Because robots reflected better than human beings. |
D.Because children wanted to affect the robots on purpose. |
A.He is optimistic about the result. | B.He doubts the result of the research. |
C.He doesn’t care about the result. | D.He is worried about the future. |

The reasons for homelessness are various, but poverty(贫穷)is undoubtedly one of the main causes. The homeless people may have become jobless and then been unable to pay their rent and so no longer have
Some homeless people are mentally ill and have no one to look after them. Some are young people who, for one reason or another, have left home and have nowhere to live. Many of them have had a serious disagreement with their parents and have left home, choosing to go to a city and live on the streets. Sometimes they have taken such action because they have been unable to get on with a step-parent.
Many homeless people get into the habit of begging to get enough money to stay alive, but many of the general public refuse to give anything to beggars. Often they are moved on by the police, being accused (指控),whether rightly or wrongly, of forceful begging . There are many who disrespect homeless people.
Some cynics(愤世嫉俗的人)declare that homeless people choose to live the life which they lead. But who would willingly choose to live in a shop doorway, under a bridge or in a cardboard box?

【推荐2】Winter Adventures Await in the Canadian Rockies
Alberta is the top destination for the outdoor wonderland experiences and the chilly winter is the hottest season of the year for you to adventure in the most beautiful, magical, powerful places on the planet and keeps you coming back. Here are tips for experiencing some of the best adventures winter has to offer in Alberta.
Hit the slopes
Set deep in what's widely regarded as the world's most scenic ski area at Banff National Park, the Lake Louise Ski Resort invites everyone from first-timers to advanced shredders to its 4, 200 acres of skiable area.
Climb a frozen waterfall
Jasper National Park, part of the Canadian Rocky Mountain Parks World Heritage site, has an area of 6, 759 square miles of mountains, glacial peaks and forests. Rivers lead to steep falls, which freeze into ice climbs as early as October and valley climbs form just a month later. While experienced climbers can cope with the frozen waterfalls without a guide, beginners need not shy away:basic training courses are offered for free.
Blaze a trail in the snow
The Athabasca Glacier is an ancient relic among the massive Columbia Ice field. While it's recommended to access the glacier only with an experienced guide, the area surrounding it offers cross-country snowshoeing trails that lead to it. No matter your mode of transport, this area is one of the darkest in Canada, which means the night sky provides a perfect backdrop for the dancing northern lights-so dress extra warm and struggle through the deep snow to glimpse one of nature's most colorful wonders.
Hidden gem
The month-long Snow-Day festival takes over Banff National Park each January. Cultural and sporting events, including ice carving and the Big Bear ski and rail competition, unfold throughout the event, but the real treat comes at the start, when live music fills the streets during the party, and a beer garden and ice fire pit keep the tourists warm.
The most splendid winter sunset can be seen throughout Alberta. As Mike Libecki, a National Geographic Adventurer of the Year, says, Alberta is one that keeps him coming back.

【推荐3】The earliest newspapers started in ancient Rome. They were handwritten news sheets. The first printed newspapers appeared in China during the Tang dynasty, which were printed from carved wooden blocks. Modern papers first appeared in Venice, Italy in the middle of the 14th century. The newspapers of today, with advertising and a mixture of political, economic, and social news and comments, were started in Britain in the mid-18th century.
The main function of newspapers is to report news. Many newspapers also provide special information to readers, such as weather reports and television timetables. They also provide comments on politics, economics, arts and culture. Almost all newspapers depend on advertising to make money. Nearly six out of ten adults in the United States and Canada read a newspaper every day. Seven out of ten read a paper each weekend. Readers search newspapers for detailed background information and analysis. This is what television and radio news reports seldom offer. Newspapers tell readers what happened, and they also help readers understand what caused an event and how it will affect the world around them.
The workers at large newspaper companies work under a lot of pressure to bring news to readers as soon as possible. Reporters, photographers, artists, and editors collect articles in just a few hours. Page designers select articles, photos, advertisements, and eye-catching headlines to make the pages, and then rush their work to the printer. Printing workers may work overnight around printing presses to churn out more than 60,000 copies per hour.

Son WH-1000XM3 Wireless Noise-Canceling Headphones for $278 ($72off)
Amazon, Best Buy
With fantastic sound, more than 30 hours of battery life, and extreme noise-canceling, the WH-1000XM3 are our favorite wireless headphones.
Apple AirPods Pro for $235 ( $15 off)
Amazon
These are Apple's newest AirPods, and we really like them. The discount isn't the greatest, but it's probably the best deal you'll find on AirPods Pro this holiday season, since they’re brand new.
Four-Driver Earbuds for 146 ($7 off)
Amazon
Most headphones have a single driver that makes all the sound, but these have four, which helps them balance frequencies more steadily, creating a wider soundstage, and providing clearer separation between guitars, keyboards and vocals(歌唱部分).
Beats Studio 3 Wireless Noise-Canceling Headphones for $200 ( $150 off)
Best Buy( $200), Amazon($250), Walmart($280)
They're a little fancy, but if you are after some well-made, stylish, and functional headphones, the Beats Studio 3 is a good option.
