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.

【推荐2】In today's world of smart phones and laptops, most people have at least one time-telling thing with them. Since these digital products are so common, is time running out for the 500-year-old watch? According to some consumers, the answer is yes. New Jersey teenager Charlie Wollman says a watch is “an extra piece of equipment with no necessary function.” Many young adults think so and use their smart phones to tell time. It is said that fewer young people wear watches today than ten years ago. As a result, some people say that the watch industry is at a crossroads.
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.
2. According to the passage, what image does a watch convey nowadays?
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.
3. Japanese watchmaker Tokyoflash is mentioned in Paragraph 4 to _________.
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
4. What may be the best title for the passage?
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.     1     Home gardeners can play an important role in supporting bees, in particular, by offering food, water, and shelter for them.

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.     2     Choose a sunny location and set plants in groups.

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.     3    

Shelter.     4     These bees don’t live in hives like honeybees but in logs, dead tree branches, even in holes in the ground. You can build a bee shelter by drilling holes in an untreated wood block. The holes should be three to five inches deep and a quarter inch in diameter.     5     Choose a site protected from wind and rain for your nest — under the eaves of a shed, for example.

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.
D.Leave an area of bare dirt for ground insects.
E.So choose wildflowers and natives whenever possible.
F.Don’t ignore the wild bees that live in North America.
G.Similar reports of disappearing bees were reported nationwide.
