1 . In the UK, electric and other low-emission（低排放）cars, vans, and buses could be given special green plates to encourage more people to buy such cars, and promote awareness for “clean” cars.
Strange as it may seem, there is some reason to believe that something as small as this could make a big difference. Already, similar ideas have been put into effect in Norway, Canada, Latvia, and China, and the results have been encouraging.
Elisabeth Costa, director of the Behavioural Insights Team, explains, “Simple changes based on behavioral science can have a big impact. Green plates would be more noticeable to road users, and this increased attraction can help normalise the idea of clean vehicles, highlighting（使突出）the changing social norms（规范）around vehicle ownership.”
Actually, hybrids and electric cars accounted for 5.5% of the cars sold in the UK in the first half of the year, compared to 4.2% for the same period in 2017.
However, colored plates can only go so far. At the end of the day, you need strong, concrete（具体的）measures if you want to support a market like electric cars. The UK already has generous allowances for electric cars, but a study for the RAC Foundation found that the lack of reliable, easy-to-use charging stations is the main roadblock to people purchasing more electric cars. This was repeated by separate research from AA, the UK’s largest motorist association, which found that although 1 in 2 young drivers want electric cars, 8 out of 10 drivers feel that the lack of adequate electrical chargers is the main reason not to buy an electric car.
Yet this all shows that more and more people are nearing a tipping point where they are willing to buy electric cars. And a small PR stunt（噱头）, the “coolness factor” of the colored plates could end up making a difference. Similarly, having red plates for the more polluting cars might also play a role.
A spokesman for the Environmental Transport Association said, “While green number plates will be positive PR for low-emission car makers and early adopters of the technology alike, to be truly effective any such measures will need to at the same time shame the drivers of the most polluting vehicles.”

2 . Half of the world's beaches could disappear by 2100, a study published in the journal Nature Climate Change suggests.
Michalis Vousdoukas, of the European Union's Joint Research Center in Ispra, Italy, was the lead researchist. "Tourist areas which have sandy beaches as their main selling point will probably face strong consequences," he said. Aside from economic value, beaches play an important environmental role. "Sandy beaches are important habitats supporting a wide range of species. They also protect the coast from the effects of storms, so without sandy beaches other inland environments can be affected by the effects of waves and saltwater entering," Vousdoukas added.
The main causes are rising sea-level and erosion (侵蚀)from storms, the study says, which warned of the near-disappearance of almost half of the world's sandy beaches by the end of the century. Beaches in the United States will be “greatly affected”，as will shorelines in Canada, Mexico, China and Chile. In the U. S. , beaches along the East Coast and the Gulf Coast will experience the most erosion.
Michalis Vousdoukas and other researchers used satellite images to track the way beaches have changed over the past 30 years and patterned how global warming might affect them in the future. They found that West Africa will see some of the worst losses, where more than 60% of sandy coastline may be lost in countries such as The Gambia and Guinea-Bissau. Australia will also take a hit:when the total length of sandy beach projected to be lost is analyzed, Australia would be hit the hardest, with more than 7,000 miles at risk.

5 . The rapid increase of the oil price has brought the world to its senses. Scientists are seeking suitable alternative (替换) but so far in vain. They are considering how they can make better use of the two other major fuels, coal and natural gas, but they have found that neither can replace oil in their economics. In recent years, there has been a growing concern for the environment and coal is not a popular fuel with environmentalists. Natural gas, the purest of the three fuels, is also the most limited in supply.
The answer would seem to lie in nuclear power stations. They need very little fuel to produce enormous amounts of power and they do not pollute the atmosphere. Their dangers, however, are so great and the costs of building them are also high. Not only could one accident in a nuclear power station spread as much radioactivity (放射物) as a thousand Hiroshima atom bombs, but the radioactive waste from these stations is extremely dangerous.
Scientists have recently turned their attention to natural sources of energy: the sun, the sea, the wind and hot spring, of which the sun seems the most promising source for the future. Houses have already been built which are heated entirely by solar energy. However, solar energy can only be collected during daylight hours, and in countries where the weather is unreliable, an alternative heating system has to be included.
However, many scientists are optimistic that new ways of generating large amounts of energy will be successfully developed, but at the same time they fear the consequences. If the world population goes on increasing at its present rate, we may, in fifty years’ time, be burning up so much energy that we would damage the earth’s atmosphere. By raising the temperature of the atmosphere,we could melt the Arctic and Antarctic ice-caps and change the pattern of vegetable and animal life throughout the world——a frightening possibility.

7 . Since the first Earth Day in 1970, American have gotten a lot “greener” toward the environment. “We didn’t know at that time that there even was an environment, let alone that there was a problem with it.” says Bruce Anderson, president of Earth Day USA.
But what began as nothing important in public affairs has grown into a social movement . Business people, political leaders, university professors, and especially millions of grass-roots Americans are taking part in the movement. “The understanding has increased many, many times,” says Gaylord Nelson, the former governor from Wisconsin, who thought up the first Earth Day.
According to US government reports, emissions (排放) from cars and trucks have dropped from 10.3 million tons a year to 5.5 million tons. The number of cities producing CO beyond the standard has been reduced from 40 to 9. Although serious problems still remain and need to be dealt with, the world is a safer and. healthier place. A kind of “green thinking” has become part of practices.
Great improvement has been achieved. In 1988 there were only 600 recycling programs; today in 1995 there are about 6 600. Advanced lights, motors, and building designs have helped save a lot of energy and therefore prevented pollution.
Twenty-five years ago, there were hardly any education programs for environment. Today, it’s hard to find a public school, university, or law school that does not have such a kind of program.“Until we do that, nothing else will change!” say Bruce Anderson.
1. According to Anderson, before 1970, Americans had little idea about ________ .| A．the social movement | B．recycling techniques |

Dear fellow students,

Dear fellow students, let's take action right now!
9 . Your next car might drive itself. After years of trials on city streets, driverless vehicles are now nearing the production phase. Last month, a driverless bus began carrying passengers through Lyon, France. Most in the automobile industry think self-driving vehicles will be on the road by 2020 or before.
Driverless cars will at first be huddled with human-driven cars. But the first places where they will become dominant（占支配地位的）are dense urban areas-precisely the spots most damaged by the automobile age. Many advanced cities are already reducing the role of human-driven cars. Driverless cars will quicken that process and will bring us great benefits.
Driverless cars will reduce accidents by around 90 percent. That's big-the annual death toll on the world's roads is about 1.2 million a year. Pollution and carbon emissions will drop, because urban driverless cars will be electric. The old, otherwise they would stay at home most of the time and the disabled and teenagers will suddenly gain mobility.
On the other hand, driverless cars will bring catastrophe（灾难）.The best thing about the automobile age is that it employs tens of millions of people to make, market, insure and drive vehicles. Over the next 20 years, most men who now drive trucks, taxis and buses will see their jobs reduced. Carmakers are especially scared. A few cars in the future might be made by tech companies such as Apple, Baidu and Google. Imaging the impact on Germany, where the automotive sector is the largest industry.
Dramatic change is coming, and driverless cars could arrive by 2020. But governments have hardly begun thinking about it. Only 6 percent of the biggest US cities have factored them into their long-term planning.
A decade ago anyone hardly saw the smartphone coming. It has brought an epidemic of mass addiction. Let's hope we do a better job of handling the driverless car.
1. The underlined words "be huddled with "in Paragraph 2 can be replaced by "________".| A．show up with | B．exist together with |
| C．get rid of | D．take the place of |
| A．Driverless cars reduce the number of human-driven cars. |
| B．Driverless cars will be powered by electricity. |
| C．Driverless cars save fuel by driving themselves. |
| D．Driverless cars will reduce too many accidents. |
| A．They will not hit the road until 2020. |
| B．They will only be used in urban areas. |
| C．They will not cause any road accident. |
| D．They aren't still seriously taken by governments. |
| A．Doubtful. | B．Negative. |
| C．Objective. | D．Worried. |
10 . Summers around the world are already warmer than they used to be, and they are going to get dramatically hotter by the century’s end if carbon pollution continues to rise. That problem will be felt most acutely in cities.
The world’s rapidly growing population coupled with the urban “heat island” effect, which can make cities up to 7.8℃ warmer than the countryside, adds up to a recipe for dangerous and potentially deadly heat.
Currently, about 54 percent of the world’s population lives in cities, and by 2050 the urban population is expected to have grown by 2.5 billion people. As those cities get hotter, weather patterns may shift and make extreme heat even more common. That will, in turn, threaten public health and the economy.
Under the high-pollution situation, currently mild Ottawa, Canada could have the tropical climate of Belize City by 2100. Mountainous Kabul, Afghanistan could feel like coastal Colombo, India. Already hot Cairo, Egypt could feel like its sweltering (闷热的) neighbor, Abu Dhabi.
The average land temperature is projected to rise 4.8℃, but due to the differences in geography, some cities will warm much more. Sofia, Bulgaria is predicted to have the biggest overall temperature shift, with temperatures rising nearly 8.4℃ by 2100. That would make its summers more like in Egypt.
The average summer temperature in Khartoum, Sudan is projected to skyrocket to 44.1℃ if carbon pollution continues to be unchecked. That shift emphasizes that unless carbon pollution is limited, the planet could be headed toward a state that humans have never experienced.
Dealing with less extreme heat makes adaptation easier and less expensive, and given that choice, perhaps it’s no surprise cities are leading the charge on climate change. They face the worst impacts of extreme heat and are home to billions. That’s why thousands of mayors from around the world have banded together and promised to reduce their emissions. That includes lots of U.S. cities committing to meet the Paris Agreement goals after President Trump announced he was pulling the U.S. out of the agreement.
