How many coins nave you got in your pocket right now? Three? Two？ A bent one？

　　With a phonecard you can make up to 200 calls without any change at all.

　　（1） What do you do with it?

　　Go to a telephone box marked（you guessed it） “phonecard”.Put in your card, make your call and when you’ve finished, a screen tells you how much is left on your card.

　　（2） Now appear in a shop near you.

　　Near each Cardphone place you’ll find a shop where you can buy one. They’re at bus, train and city tube stations（地铁）.

　　Many universities, hospitals and clubs. Restaurants and gas stations on the highway and shopping centres. At airports and seaports.

On April 24^th, another natural disaster—the oil spill(泄露) in the Gulf of Mexico, happened. Millions of dollars have been used to help stop the spill and to clean up the animals, beaches, and land spoiled by the oil．Unfortunately, when many of these chemicals are used, more damage is caused to the environment, especially to lives in the sea．

But governments seem to accept the risk of transporting millions of tons of oil by ship every day so that we can fill up our cars and drive around and cause even more environmental damage．Interestingly, the biggest companies in the world produce cars, and the next biggest supply the gasoline to make them run.

Of all of today’s environmental disasters, an oil spill may actually be one of the least serious．Although oil is poisonous, it is a natural material．In the end, it breaks down naturally．In 1967 the tanker Torrey Canyon sank off the Scilly Isles near the coast of England and spilled 120,000 tones of oil into the ocean．If you go there today, you will find it hard to see any sign that it ever happened．      

However, we should be thinking more about reducing our dependency on oil．Governments should be encouraging research into new technologies, such as cars run by solar power（太阳能）, electricity, hydrogen, and so on．Much of this research, in the past, was stopped by the oil, gas, and coal．

If the world’s millions of cars were 10% more efficient（高效的）,we would need many fewer tankers crossing the oceans each year．If this happened, the risks of oil spills would be reduced, and the air we breathe would be cleaner and fresher, too．

What is the passage mainly talking about?

A．Oil spills pollution．             B．What oil pollution is．

C．Oil tanker accidents.              D．How to reduce oil pollution.

How does the author support the idea that oil spills are not as serious as people believe?

A．By giving a description．          B．By making an argument．

C．By giving an example．           D．By drawing a diagram(图表)．

What does the underlined word "risk" in Paragraph 2 refer to?

A．Transportation depending more on oil．

B．Poisonous oil breaking down naturally．

C．Millions of tons of oil spilling into the sea．

D．More environmental damage being caused．

Which suggestion is made for reducing oil tank accidents according to the passage?

A．We should build safer tankers in the near future．

B．We should develop new technologies to cut oil use．

C．Tankers should not be allowed to sail near the coastlines．

D．Countries should build more oil pipelines under the sea．

Where can you read this article?

A．In a story book．        

B．In a science magazine．

C．In a novel.   

D．In a brochure．

A recent study, while showing a generally positive attitude toward science, also suggests a widespread worry that it may be “running out of control”. This idea is dangerous.

Science can be a force for evil as well as for good. Its applications can be channeled either way, depending on our decisions. The decisions we make, personally or collectively, will determine the outcomes of science. But here is a real danger. Science is advancing so fast is so strongly influenced by businesses that we are likely to believe whatever decisions we come to will make little difference. And, rather than fighting for the best possible policies, we may step back and do nothing.

Some people go even further. They say that despite the moral and legal objections （反对）, whatever is scientifically possible will be done ——somewhere, sometime. They believe that science will get out of control in the end. This belief is dangerous too, because it a fuels sense of  hopelessness and discourages them from making efforts to build a safer world.

In our interconnected world, the lack of agreement in and of the world of science can lead to the failure to control the use of science. Without a common understanding, the challenges of “controlling” science in this century will be really tough. Take human cloning for example. Despite the general agreement among scientists on its possible huge impact （影响） on traditional moral values, some countries still go ahead with the research and development of its related techniques. The outcomes are hard to predict.

Therefore, discussions on how science is applied should be extended far beyond scientific societies. Only through the united efforts of people with hope, can we be fully safe against the misuse of science and can science best serve mankind in the future.

What can we conclude from the recent study?

A. People think highly of science.

B. People hold mixed opinions about science.

C. Science is getting dangerously out of control.

D. Science is used for both good and bad purposes.

According to the passage, what will happen if we hold that science is getting beyond control?

A. The development of science will hopelessly slow down.

B. Businesses will have even greater influence on science.

C. The public will lose faith in bringing about a bright future.

D. People will work more actively to put science under control.

The discussion should reach beyond scientific societies because __________.

A. scientists have failed to predict the outcomes

B. the ties between different areas need strengthening

C. united efforts are necessary for the development of science

D. people need to work together to prevent the bad use of science

What is the main idea of the passage?

A. Science and its applications bring us many dangers.

B. The development of science mostly lies in people’s attitudes.

C. Mankind can largely take control of science with their efforts.

D. The future of science will be influenced by the dangerous ideas.

     Australia’s Great Barrier Reef will lose most of its coral cover by 2050 and, at worst, the world’s largest coral system could collapse by 2100 because of global warming, a study recently said.

     The study by Queensland University’s Center for Marine Studies, commissioned (委托) by the Worldwide Fund for Nature, said that the destruction of coral on the Great Barrier Reef was unavoidable due to global warming, regardless of what actions were taken now. “Under the worst-case scenario, coral populations will collapse by 2100 and the reestablishment of coral reefs will be highly unlikely over the following 200-500 years,” said the report entitled “Implications (可能的影响) of Climate Change for Australia’s Great Barrier Reef.”

     The Great Barrier Reef is the world’s largest living reef formation stretching 2,000 km north to south along Australia’s northeast coast. “Only if global average temperature change is kept to below two degrees Celsius can the Reef have any change of recovering from the predicted damage,” the report said. Coral has a narrow comfort zone and is highly stressed by a temperature rise of less than one degree Celsius. Water temperature rises of less than one degree coincided (同时发生) with the world’s worst recorded coral bleaching (颜色变淡) period in 1988. The warmer water forces out the algae (海藻) that give coral its color and, if all are lost, the coral dies and the reef will die out. In 1988, 16 percent of the world’s coral died, with 46 percent of the Indian Ocean coral destroyed.

     Scientists express water temperatures to rise this century by between two and six degrees Celsius. “There is little to no evidence that corals can adapt fast enough to match even the lower  temperature rise,” said the report. Over-fishing and pollution from coastal farms were also contributing to the destruction of coral on the Great Barrier Reef.

     The Great Barrier Reef supports huge fishing and tourism industries. Even under favorable conditions tourists would only be able to experience real corals in reef “theme parks”.
