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.
【小题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．as easy as |
| C．much harder than | D．as hard as |
| A．rubbish（垃圾） | B．noise pollution |
| C．air 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. |

Electrical devices(仪器)could soon use power made by human energy. Scientists say
they have developed an experimental device that produces electricity from the physical movement of a person walking. British scientist Max Donelan and other scientists in Canada and the United States developed the device.
The device connects to a person’s knee. As the person walks, the device captures energy each time the person slows down. To do this, the device helps with the slowing down movement of the leg. The movements of the walking person push parts of a small machine
that produces electricity. Using the device, an adult walking quickly could produce thirteen watts of electricity in just a minute. Donelan says walking at that speed could produce enough power to operate a laptop computer for six minutes.
There are several possible uses for the device. Developers say it could help people who work in areas without electricity to operate small computers. The device could also be used in hospitals to operate heart pacemakers(起搏器). It could even be used to assist in the movement of robotic arms and legs.
The experimental version of the device weighs about one and a half kilograms, but it is too costly for most people to buy. But the researchers hope to make a lighter, less costly version. An improved version shou1d be ready in one year.
The developers hope the device will one day help developing countries. Near1y twenty five percent of people around the world live without electric power.
A similar product was invented in 2005 by Larry Rome of the University of Pennsylvania. He created a bag carried on a person’s back that also produces power from wa1king.
The knee device does not produce as much electricity as the bag. But the bag requires the walker to carry a load of twenty to thirty kilograms.
【小题1】The second paragraph mainly talks about .
| A．who developed the device |
| B．how the device works |
| C．several possible uses for the devices |
| D．how much electricity the device can produce |
| A．It is too heavy for the walker to bear. |
| B．It is too complex for people to use. |
| C．It is too expensive for most people to afford. |
| D．It will slow down one’s walking speed. |
| A．produces power without adding more loads to the walker |
| B．can produce more power in a much shorter time |
| C．needs to be equipped with a battery |
| D．can help the walker wa1k faster |
| A．help housewives operate the washing machine |
| B．make it much easier for us to go online |
| C．produce more electricity than that invented by Larry Rome |
| D．be applied in medicine to operate heart pacemakers |
| A．First device powered by walking wi1l soon be on the market |
| B．Advanced technology brings in a new way to operate heart pacemakers |
| C．Device gives new meaning to the idea of power walking |
| D．Human energy will become a main source of electricity |

A team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech integrated systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.
“It’s extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components (元件),” said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. A few years ago, his team got the go-ahead to start piecing together the components. “The added difficulty with a project like this is that actually none of those components are off the shelf and so we have to develop them all on our own,” he said.
They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings has a number of interdependencies on the individual components, each of which individually has to perform well, but then has to be matched well to everything it’s connected to,” said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.
While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites, in farmers’ fields or on the battlefield. “Basically it should be able to take off, land and fly around,” he said.
Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications. “You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead,” he said. “So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day to day basis.”
【小题1】The robotic fly project has been conducted __________.
| A．just by accident |
| B．within a decade |
| C．just by a professor |
| D．for more than ten years |
| A．they had no model in their mind |
| B．they did not have sufficient time |
| C．they had no ready-made components |
| D．they could not assemble the components |
| A．The robotic flyer is designed to learn about insects. |
| B．Animals are not allowed in biological experiments. |
| C．There used to be few ways to study how insects fly. |
| D．Wood’s design can replace animals in some experiments. |

Bend over, take a deep breath and drink some water! This is just one of hundreds of tips you might get if you have the hiccups(打嗝). Hiccups are so mysterious. We really don’t know why they start and why they stop.
Everyone has a favorite cure(治愈方法) for a case of the hiccups. Some people think that a good scare(惊恐) is necessary to get well. Others eat a teaspoon of sugar. Still others drink a glass of water with a knife in it.
An American man named Jack O’Leary said he had hiccupped 160 million times over a period of eight years. He tried 60,000 cures, but none of them worked. At last he prayed to Saint Jude, the saint of Hopeless cases, and his hiccupping stopped immediately.
It took a British plumber eight months to cure his hiccups. People from all over the world wrote him letters with suggestions for getting well. He tried them all, but the hiccups continued. Finally, he drank a “secret” mixture someone had sent him. By that evening his hiccups were gone.
Why did these cures work for these two men? No one really know. But people who have studied many cases of hiccups have an idea – hiccups usually go away if you believe in the cure.
【小题1】. How did Jack O’Leary stop his hiccups?
| A．He took a deep breath. | B．He prayed to Saint Jude |
| C．He ate a teaspoon of sugar. | D．He drank a “secret” mixture. |

Animals are natural resources that people have wasted all through our history.
Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the earth forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger.
Why should people care? Because we need animals. And because once they are gone, there will never be any more.
Animals are more than beautiful or interesting or a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems.
For example, when farmers killed large numbers of hawks(鹰), the farmers’ stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice. With no hawks to keep down their numbers, the rats and mice multiplied(繁殖) quickly.
Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger.
Quite a few countries have passed laws. These laws forbid the killing of any animal or plant on the danger list. Slowly, the number of some animals in danger is growing.
【小题1】Why do people kill animals?
| A．They kill animals for something they need. |
| B．They kill animals to raise some money. |
| C．Animals destroy their natural resources. |
| D．Animals create many problems. |
| A．they give us a source of food |
| B．they are beautiful and lovely |
| C．they keep the balance of nature |
| D．they give us a lot of pleasure |
| A．People care much about animals because they need them. |
| B．Once a certain kind of animal is gone forever, there will never be any more. |
| C．Killing all rats and mice may cause some new problems. |
| D．People must not kill any animal or plant. |

Ask someone what they have done to help the environment recently and they will almost certainly mention recycling. Recycling in the home is very important, of course. However, being forced to recycle often means we already have more material than we need. We are dealing with the results of that over-consumption in the greenest way possible, but it would be far better if we did not need to bring so much material home in the first place.
The total amount of packaging has increased by 12% between 1999 and 2005. It now makes up a third of a typical household's waste in the UK. In many supermarkets nowadays food items are packaged twice with plastic and cardboard.
Too much packaging is doing serious damage to the environment. The UK, for example, is running out of it for burying this unnecessary waste. If such packaging is burnt, it gives off greenhouse gases which go on to cause the greenhouse effect. Recycling helps, but the process itself uses energy. The solution is not to produce such items in the first place. Food waste is a serious problem, too. Too many supermarkets encourage customers to buy more than they need. However, few of them are coming round to the idea that this cannot continue, encouraging customers to reuse their plastic bags, for example.
But this is not just about supermarkets. It is about all of us. We have learned to associate packaging with quality. We have learned to think that something unpackaged is of poor quality. This is especially true of food. But it is also applied to a wide range of consumer products, which often have far more packaging than necessary.
There are signs of hope. As more of us recycle, we are beginning to realize just how much unnecessary materials are collected. We need to face the wastefulness of our consumer culture, but we have a mountain to climb.
【小题1】What does the underlined phrase "over-consumption" refer to?
| A．Using too much packaging. |
| B．Recycling too many wastes. |
| C．Having more material than is needed. |
| D．Making more products than necessary. |
| A．the tendency of cutting household waste |
| B．the increase of packaging recycling |
| C．the fact of packaging overuse |
| D．the rapid growth of supermarkets |
| A．means burning packaging for energy |
| B．helps control the greenhouse effect |
| C．is the solution to gas shortage |
| D．leads to a waste of land |
| A．Unpackaged products are of bad quality. |
| B．Supermarkets care more about packaging. |
| C．Other products are better packaged than food. |
| D．It is improper to judge quality by packaging. |
| A．Needless material is mostly recycled. |
| B．Fighting wastefulness is difficult. |
| C．People like collecting recyclable wastes. |
| D．The author is proud of their consumer culture. |

The health of millions could be at risk because medicinal plants are being used up.These plants are used to make traditional medicine，including drugs to fight cancer.“The loss of medicinal plants is a quiet disaster，”says Sara Oldfield，secretary general of the NGO Botanic Gardens Conservation International.
Most people worldwide (including 80 percent of all Africans)rely on herbal medicines(草药)which are got mostly from wild plants.But some 15,000 of the 50,000 medicinal species are under threat of dying out，according to a report from the international conversation group Plantlife.Shortages have been reported in China，India，Kenya，Nepal，Tanzania and Uganda.
Over?harvesting does the most harm，though pollution and competition from invasive(侵略性的)species are both responsible.“Businessmen generally harvest medicinal plants，not caring about sustain ability，”the Plantlife report says.“Damage is serious partly because they have no idea of it，but it is mainly because such collection is unorganized.” Medicinal trees at risk include the Himalayan yew and the African cherry，which are used to treat some cancers.
The solution，says the report's author，Alan Hamilton，is to encourage local people to protect these plants.Ten projects studied by Plantlife in India，Pakistan，China，Nepal，Uganda and Kenya showed this method can succeed.In Uganda the project has kept a sustainable supply of low?cost cancer treatments，and in China a public run medicinal plant project has been created for the first time.
“Improving health，earning an income and keeping cultural traditions are important in encouraging people to protect medicinal plants，”says Hamilton.“You have to pay attention to what people are interested in.” Ghillean Prance，the former director of the Royal Botanic Gardens at Kew in London，agrees that medicinal plants are in need of protection.
“Not nearly enough is being done，”he told New Scientist.“We are destroying the very plants that are of most use to us.”
【小题1】What is the passage mainly about?
| A．The function of medicinal plants. |
| B．The importance of traditional medicine. |
| C．More and more people rely on herbal medicines. |
| D．The dangerous situation of medicinal plants and ways of protecting them. |
| A．About 30% of medicinal species are at risk of dying out. |
| B．Medicinal plants are mainly used to treat cancers. |
| C．80% of African countries are reported to be short of medicinal plants. |
| D．The problem of the loss of medicinal plants appeared suddenly. |
| A．A lack of knowledge of sustainability. |
| B．Invasion by other species. |
| C．Environmental pollution. |
| D．Improper harvesting. |
| A．Improving people's health. |
| B．Letting people earn more. |

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.
【小题1】The underlined word “distracted” in the article is closest in meaning to “________”．
| A．directed | B．discouraged |
| C．attacked | D．disturbed |
| A．optimistic | B．pessimistic |
| C．doubtful | D．cautious |
| A．Learning Kit | B．Campus Trends |
| C．Entertainment | D．Technology |
