What's going to happen in the future? Will robots take over our planet? Will computers become smarter than us? Not likely. But here are some things that scientists say are most likely to happen 10 to 30 years later from now, according to the BBC.
1.Digital money
We used to pay with cash for everything we bought. Now when we swipe(刷) our bus pass or use a credit card to shop online, money is spent without us even seeing it. In fact, we are already using one type of digital money.
You have to admit that using a card is much easier than searching your pockets for change. It is also safer than carrying a lot of cash.
When ATM cards were first introduced, they were not accepted everywhere. But now it's hard to live without them. People in Sweden completely stopped using cash last year, according to the Associated Press, and the US might be next.
2.Bionic(能力超人的)eye
It's no longer something only in a scifi movie. People who are blind may have a chance to get their sight back—by wearing bionic eyes.
A blind eye can no longer sense light, but a bionic eye can use a camera to “see” the environment and send data directly to the brain.
Although the bionic eye that's out now only allows patients to see lights and unclear shapes, a highresolution(高清晰度的) version could be just a few years away.
3.Selfdriving cars
Everything is going automatic these days—washing machines, ticket selling machines and even cars. Unlike a human driver, a selfdriving car won't get distracted by a phone call, the radio or something outside the window. Sensors and cameras on the car would allow it to stick strictly to the rules of the road and keep a safe distance from other cars. This would greatly reduce the number of road accidents. You could even take a nap while the car drives itself.
Many vehicle companies are now planning selfdriving cars. “By 2040, driverless vehicles will be widely accepted and possibly be the dominant vehicles on the road,” said Jeffrey Miller, professor at the University of Alaska Anchorage, US, in Wired magazine.
【小題1】The underlined word “distracted” in the article is closest in meaning to “________”.
A.directed | B.discouraged |
C.a(chǎn)ttacked | D.disturbed |
A.optimistic | B.pessimistic |
C.doubtful | D.cautious |
A.Learning Kit | B.Campus Trends |

The world itself is becoming much smaller by using modern traffic and modern communication means. Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest problems is pollution. To pollute means to make things dirty. Pollution comes in many ways. We see it, smell it, drink it and even hear it.
Man has been polluting the earth. The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. When the land was used up or the river was dirty in one place, man moved to another place. But this is no longer true.
Man is now slowly polluting the whole world.
Air pollution is still the most serious. It’s bad for all living things in the world, but it is not the only one kind of pollution. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us angry more easily.
Many countries are making rules to fight pollution. They stop people from burning coal in houses and factories in the city, and from putting dirty smoke into the air. Pollution by SO2 is now the most dangerous kind of air pollution. It is caused by heavy traffic. We are sure that if there are fewer people driving, there will be less air pollution.
The earth is our home. We must take care of it. That means keeping the land, water and air clean. And we must take care of the rise in pollution at the same time.
【小題1】 _______, our world is becoming much smaller.
A.Because of the rise in pollution |
B.Thanks to science development |
C.Because the earth is being polluted day and night |
D.Because the earth is blown away by the wind every year |
A.much easier than | B.a(chǎn)s easy as |
C.much harder than | D.a(chǎn)s hard as |
A.rubbish(垃圾) | B.noise pollution |
C.a(chǎn)ir pollution | D.water pollution |
A.Many countries are making rules to fight pollution. |
B.The pollution of the earth grows as fast as the world population does. |
C.The problem of pollution is not so serious because there are not so many people living on the earth. |
D.If people could go to work by bus or bike instead of car or motorbike, it would be helpful in fighting against the problem of SO2. |

What do you use to get around town? A car? A bike? Your feet ? perhaps you should try a segway!
The Segway is perfect for short journeys. It’s an electric vehicle that consists of a platform between two wheels, with a pole that connects the platform to the handlebars. To ride it , you step up onto the platform, and control the Segway by moving your body. Lean forwards to go faster, and back-wards to slow down.
On older models, direction was controlled by a twist grip(扭轉(zhuǎn)把手)on the left handlebar. This varies the speeds between the two motors, and a decrease in the speed of the left wheel would turn the Segway to the left . With newer models you simply lean to the left or right. Meanwhile, a gyroscope (陀螺儀)detects your movements and prevents the machine from falling over. The Segway has a maximum speed of 19 km per hour and a range of about 38 km. after that, you need to plug it and recharge the battery.
Segways are used for a variety of purposes. People with mobility problems can now enjoy walks in the country with their friends and family. Some golfers see them as an alternative to the golf cart . And dog owners now have an easier way to take the dog to the park. A few police forces use Segways, too. They allow officers to move quickly while maintaining contact with the public. They’re also becoming a common sight on airport . However, the most popular use is in tourism , particularly for city tours . Visit any major tourist city in summer, sit outside a cafe for a while and there’s a good chance you’ll see a group of tourists passing on Segways.
【小題1】How do you turn to the left on a Segway of the new model?
A.Lean to the left | B.Adjust the twist grip |
C.Press the left bar | D.Control the gyroscope |
A.Less than 19 km | B.About 19 km |
C.About 38 km | D.Over 45 km |
A.families | B.golfers |
C.police | D.tourists |
A.Introduction→Ways of application→ structure→Principle of operation |
B.Introduction→ Principle of operation→Structure →Ways of application |
C.Introduction → Structure → Principle of operation →ways of application |
D.Structure→ Introduction→Principle of operation→Ways of application |

For the first time, researchers have discovered that some plants can kill insects in order to get additional nutrients. New research shows that they catch and kill small insects with their own sticky hairs near the roots and then absorb nutrients through their roots when the insects are killed and fall to the ground.
Professor Mark Chase, of Kew and Queen Mary, University of London, said: “The cultivated (改良的) tomatoes and potatoes still have the hairs. Tomatoes in particular are covered with these sticky hairs. They do trap small insects on a regular basis. They do kill insects.”
The number of these carnivorous plants is thought to have came up to 50 percent and many of them have until now been wrongly regarded as among the most harmless plants. Among them are species of petunia(矮牽牛), some special tobacco plants and cabbages, some varieties of potatoes and tomatoes, etc. Researchers at Royal Botanical Gardens Kew, which carried out the study, now believe there are hundreds more killer plants than previously realized.
It is thought that the technique was developed in the wild to get necessary nutrients in poor quality soil and even various plants grown in your vegetable garden still have the ability.
The researchers, publishing their finding in the Botanical Journal of the Linnean Society, said: “We may be surrounded by many more murderous plants than we think.” “We are accustomed to thinking of plants as being immobile and harmless, and there is something deeply frightening about the thought of meateating plants,” they added.
【小題1】Tomatoes and potatoes kill insects to ________.
A.get more sticky hairs |
B.make themselves grow better |
C.make their roots stronger |
D.a(chǎn)void falling down to the ground |
A.fastgrowing | B.harmless |
C.insectkilling | D.nutritious |
A.evolution of species |
B.helps from other garden plants |
C.a(chǎn)rtificial cultivation |

You may be fascinated with pictures of animals in the wild. You might have imagined yourself taking pictures of animals that are rarely seen in the city. If you do get that chance, you may want to consider the following tips or rules.
First of all, a lot of professional photographers give respect to these animals and the environment they are in. Just remember that you should respect the animals and the environment in case these animals bite or hurt you.
Keep in mind that you are taking pictures of real, live, wild animals. A wild animal may bite to protect itself. You must be sensitive while taking their pictures and be gentle in all your movements. Do not feed the animals, or interact with animals that are sleeping or caring for their young.
If you are going to a place where it is privately(私人)owned, you’d better get the owner’s permission first before you start taking pictures.
Change the flash of your camera to natural light, so the animals will not be frightened or surprised when you start shooting. Animals do not react well when they are surprised.
Be very patient. Make sure you are aware of the changes in behavior of the animal and its moods. Be familiar with the animals’ natural habitat.
Now if those rules are clear, it is time for planning. Consider the weather; some animals do not go out when it is raining while some animals love the rain. Therefore, a little research on the weather will not hurt. You should consider taking pictures after sunrise and before sunset. Now if the animal is nocturnal(夜間活動的), then you should prepare to battle not only the wild but also the darkness.
An adventure in the wild will make you very excited. However, you should be well equipped, have experts to back you up, and also a permit for doing the photo shoot. If you do not have any of these, then maybe you should consider visiting the zoo instead.
【小題1】The main purpose of the author in writing this passage is .
A.to call for us to protect animals |
B.to show where to buy pictures of animals |
C.to explain how to get along with wild animals |
D.to give us tips on taking pictures of animals in the wild |
A.Respecting the animals. |
B.Making gentle movements. |
C.Making the animals happy. |
D.Changing the flash of your camera to natural light. |
A.a(chǎn)sk the owner to take pictures for us |
B.a(chǎn)sk for the owner’s permission first |
C.make sure the owner is present when we take pictures |
D.take pictures when the owner is feeding animals |
A.most animals love being taken pictures of |
B.we have to finish the pictures before sunset |

Growers around the world are using new methods to grow grapes to make wine. They use natural and organic methods to control harmful insects and weeds instead of using chemicals. Now, a winery in Canada has adopted a natural way to control its grapevines (葡萄藤). The Featherstone Winery is in southern Ontario. The grapevines, like other plants, need to be cut every year.
Cutting grapevines must be done very carefully. Only a targeted area of leaves is removed from the lower part of the vines to help the grapes grow better. But at the Featherstone Winery, no man or machine does the cutting. Instead, the job is done by 40 little wooly lambs.
David Johnson owns the vineyard (葡萄園). He says he learned about using lambs while visiting wineries in New Zealand. The young lambs are perfectly designed to do the job. They eat the grape leaves on the lower parts of the vine. But they are not tall enough to reach the grapes. They only weigh about 22 kilograms, so they do not beat down the soil. And their waste makes good organic fertilizer. In addition, using the lambs costs much less than hiring workers to cut the vines for seven weeks in summer. And when the cutting is done in August, the lambs become tasty dishes.
Mr. Johnson says he had a difficult time finding enough lambs to do the job. There are about 50 million lambs in New Zealand. But there are not nearly as many in Ontario. Also, some organic pesticides (殺蟲劑) are harmful to lambs. And the lambs must be watched to make sure they do not eat too much of the grapevines.
David Johnson says the lambs help him carry out his environmental ideas about farming. They are lovely and peaceful and he likes having them in his vineyard. People visiting the vineyard also enjoy watching the lambs do their job.
【小題1】Farmers who grow grapes with natural and organic methods ________.
A.don't cut grapevines every year |

Researchers have developed new software using smart phones’GPS and imaging abilities that determine the exact location of distant objects as well as monitor the speed and direction of moving objects.The software could eventually allow smart phone-armed soldiers to target the location of their enemies.On the home front,the software could be used by everyone,including golfers judging distance to the green and biologists documenting the location of a rare animal without disturbing it.
“The great advantage of a Smartphone is that it provides so many tools in a single,readily available,relatively inexpensive package,”said Qia Wang,a doctoral student who led the development of the software.“For example,on the battlefield,a soldier needs a rangefinder,compass,GPS and other tools to get information before calling in an air strike.With our software,the soldier can have all those instruments in one device that can be purchased off the shelf.When that soldier returns from War,she can use the same Software to protect her family by clocking a speeder near her children’s school and catching the criminal on video.”
Wang and his colleagues developed their software to locate and track:
Targets of known size—when the size of the target is known.a(chǎn) single image is enough to pinpoint the target’s location.
Targets of unknown size—If the exact size of a target is unknown,the software uses two images to triangulate the location of the target·
Moving targets—By taking a short video of a moving target,the smartphone software can calculate how fast the target is moving and in what direction it is going.
“Currently,our software is limited by the physical abilities of smartphone hardware,but the devices are improving rapidly,”Wang said.“We expect that improvements in GPS accuracy,battery life and camera resolution will allow our software to make even more accurate observations.”
【小題1】From Paragraph 1 we can know that the new software can.
A.determine the speed of moving objects |
B.1ocate objects in the distance exactly |
C.defend soldiers against their enemies |
D.help biologists protect rare animal |

Some weightloss camps, which are rare in China just a few years ago,have multiplied in Beijing, Qingdao, Shenzhen,and other cities. Today about 15 percent of adults, or 200 million Chinese, are reportedly overweight.Of these, 90 million—about 7 percent—are obese(極肥胖的).
Experts say the obesity epidemic(流行病) is spreading to children, though more slowly than in adults. The obesity, they say, will do harm to the health of China’ s citizens and economy.“We're seeing a very large number of teenagers who are quite heavy and aren't moving much,” said Barry Popkin, a nutrition(營養(yǎng)) professor. Popkin carries out an ongoing healthandnutrition survey of 16,000 households in China. He says more kids today are overeating and putting on weight “quite quickly.” In just ten years China‘s childhood obesity rate has doubled,with the greatest gains coming in urban areas.“In big cities it's a big problem.”
Some experts blame the extra fat on a range of factors, many of them tied to China’ s rapidly changing economy and culture. The diets of Chinese adults and children are far higher in meats, fish, eggs, dairy products, fats and sugars than ever before. In addition,kids—especially city dwellers—are more sedentary today and spend more time indoors in front of homework, television,computer games, and the Internet.
Shuwen Ng,a health economist, says that kids in China now have pocket money, and they spend a portion of it on junk food. Ng adds that advertising and peer groups influence kids' food choices. Certain foods, such as new candies or fast food, have attractive features.
China’ s childhood obesity rate stillfall behind that of the United States, where some 15 percent of kids are said to be obese. But the longterm effects are equally serious.
【小題1】According to the passage we know________.
A.weightloss camps have been very popular in China six years ago |
B.a(chǎn)bout 290 million Chinese are overweight in China in all |
C.in China childhood obesity rate in rural areas is lower than that in major cities |
D.America’ s childhood obesity rate is lower than China’s |
A.Advertising on some new candies. |
B.ignorance of weight-control. |
C.Playing computer games for long time. |
D.Having pocket money. |
A.confident | B.patient | C.energetic | D.inactive |
A.obesity explosion in China will affect the United States |
B.there are great difference in kids' food choices now |
C.junk food leads to childhood obesity |
D.city children eat more than rural children |
A.Chinese Childhood Obesity problem |
B.Weightloss Camps in China |
C.Obesity problem's influence on Chinese Economy |
D.Obesity problem in China and America |
