Climate change，pollution，overuse of water and development are killing some of the world’s most famous rivers including China’s Yangtze．India’s Ganges and Africa’s Nile．WWF said on Tuesday．At the global launch of its report “World’s Top 10 Rivers at Risk”，the group said many rivers could dry out, affecting hundreds of millions of people and killing unique aquatic（水生的）life．
“If these rivers die，millions will lose their livelihoods，biodiversity（生物多样性）will be destroyed on a massive scale，there will be less fresh water and agriculture，resulting in less food security，”said．Rayi Singh，secretary—general of WWF—India．The report launched ahead of “World Water Day” today，also cited the Rio Grande in the United States，the Mekong and Indus in Asia，Europe’s Danube, La Plata in South America and Australia’s Murray—Darling as in need of greater protection．
Rivers are the world’s main source of fresh water and WWF says about half of the available supply is already being used up．Dams have destroyed habitats and cut rivers off from their flood plains．while climate change could affect the seasonal water flows that feed them，the report said．Fish populations，the top source of protein and overall life support for hundreds of thousands of communities worldwide，are also being threatened, it found．．The Yangtze basin is one of the most polluted rivers in the world because of decades of heavy industrialization，damming and huge influxes（流入）of sediment（积淀）from land conversion．
Climate change，including higher temperatures，also means serious consequences for fishery productivity，water supply and political security in Africa’s arid Nile basin．Tributaries（支流）flowing into the Ganges are drying up because of irrigation，WWF said．

The Galapagos Islands are in the Pacific Ocean, off the western coast of South America They are a rocky, lonely spot, but they are also one of the most unusual places in the world. One reason is that they are the home of some of the last giant tortoises（乌龟）left on earth.
Weighing hundreds of pounds, these tortoises go slowly around the rocks and sand of the islands. Strangely, each of these islands has its own particular kinds of tortoises. There are seven different kinds of tortoises on the eight islands, and each kind is slightly different from the other.
Hundreds of years ago, thousands of tortoises were around these islands. However, all that changed when people started landing there. When people first arrived in 1535, crews would seize as many tortoises as they could. They would roll the tortoises onto their backs when they were brought onto the ships. The tortoises were completely helpless once on their backs, so they could only lie there until used for soups and stews. Almost 100,000 tortoises were carried off in this way.
The tortoises faced other problems, too. Soon after the first ships, settlers arrived, bringing pigs, goats, donkeys, dogs and cats. A11 0f these animals ruined life for the tortoises. Donkeys and goats ate all the plants that the tortoises usually fed on, while the pigs, dogs and cats ate thousands of baby tortoises each year. Within a few years, it was hard to find any tortoise eggs-or even any baby tortoises.
Finally, in the 1950s, scientists decided that something must be done. The first part of their plan was to remove as many cats, dogs and other animals as they could from the islands. Next, they tried to make sure that more baby tortoises would be born; This slow, hard work continues today, and, thanks to it, the number of tortoises is now increasing every year. Perhaps these wonderful animals will not disappear after all

The quality of drinking water in Shanghai will meet European Union standard by 2010 and, a decade later, citizens in Shanghai will drink the best water in the world.
These were the goals set out by the Shanghai Water Authority. With the city’s population expected to increase only slightly and the economy to boom by 2020, Chen Yin, and official with the water authority, said Shanghai’s water consumption will not increase from its present amount.
Zhang Yue, director of the Urban Construction Division under the Ministry of Construction, said, “Shanghai is the first city in the country to publicize these ambitions. They will not be easy to achieve.”
He said water saving will help keep the sustainable development of China’s economy.
Saving one cubic meter of water means saving the city’s infrastructure（基础设施）costs by 10,000 Yuan. Last year, Shanghai saved 300 million cubic meters of water either from readjustment of industrial structure or the employment of new technology.
“The aim is to arouse public awareness of the seriousness of water shortages,” Chen said. “The abundant surface water and amount of rain of the city are so misleading that they result in improper use of water.”
Shanghai lacks drinkable water. The Huangpu River, which supplies 80 percent of the city’s drinkable water, is nearing exhaustion.
The city, therefore, has been exploring new sources from the Yangtze River and growing forests along it to conserve quality water.
Besides penning regulations, the authority is popularizing technology among the public to efficiently cut the amount of water used.
At present, the city has 600，000 family toilets, each using 13 liters of water per flush. These are to be renovated（整修）to use only 9 liters of water per flush.
The authority is renovating the first 200 toilets for households – at a cost of 40 Yuan each.
In three years, all the toilets will be renovated, which saves the city nearly 15 million Yuan every year in water conservation.
Another task the city is engaged in is the treatment of sewage（污水）to improve the water environment.
At present the city can only treat 44 percent of its daily 5.04 million tons of waste water. To meet the total demand, 27 more sewage treatment factories are to be established with an estimated investment of 18 billion Yuan.
【小题1】People in Shanghai get their daily water mainly from now.
| A．the underground | B．the rain |
| C．the Yangtze River | D．the Huangpu River |
| A．the renovating of family toilets will save plenty of water |
| B．about half of waste water has been treated already |
| C．advanced technology makes people use water as much as possible |
| D．there is plenty surface water and large amount of rain at present |
| A．make people’s living more convenient |
| B．improve people’s living standards |
| C．ease employment pressure |
| D．meet the total demand of water |
| A．a, b, c, d | B．b, c, e, f | C．b, c, d, e | D．a, b, e, f |
| A．the boom of economy will need a larger amount of water in the future |
| B．citizens today in Shanghai drink the best quality of water in the world |
| C．not everyone today in Shanghai is aware of water shortage |
| D．all the family toilets will be renovated to save water within 3 years |

SAN FRANCISCO—A phone app (应用程序) in San Francisco gives information about open parking spots. City officials in San Francisco introduced the app to try to reduce traffic jams in the city, but some say it raises safety concerns.
In this city, drivers searching for parking spots lead to 30 percent of all downtown jams, city officials think. Now San Francisco has found a solution—a phone app for spot-seekers that displays information about areas with available spaces. The system, introduced last month, relies on wireless sensors (感应器) fixed in streets and city garages that can tell within seconds if a spot has opened up.
Monique Soltani, a TV reporter, said she and her sister spent 25 minutes on Friday trying to park. “We were praying to the parking god that we’d find a spot,” she said. “If we had the app, we would not have to pray to the parking god.” But the system could come with serious consequences.
Some people say that drivers searching for parking could end up focusing on their phones, not the road. “It could be really distracting (使分心的),” said Daniel Simons, a professor of psychology at the University of Illinois.
City officials acknowledge the potential problem. They are urging drivers to pull over before they use the city’s iPhone app, or to do so before they leave home. Nathaniel Ford, executive director of the San Francisco Municipal Transportation Agency, said safety could actually improve if drivers quickly found a spot instead of circling and getting frustrated.
San Francisco has put sensors into 7,000 parking spots and 12,250 spots in city garages. If spaces in an area open up, the sensors communicate wirelessly with computers that in turn make the information available to app users within a minute, said Mr. Ford, of the transportation agency. On the app, a map shows which blocks have lots of places (blue) and which are full (red).
More than 12,000 people have downloaded San Francisco’s app, which is available now only for the iPhone but which city officials say they hope to bring to all similar devices.
When it is started up, the city’s parking app warns drivers not to use the system while in motion. But safety advocates said that might not be sufficient. After all, they say, texting while driving is illegal in California and in many states, but a number of surveys, including one by the Pew Research Center, show that many Americans do it anyway.
Elizabeth Stampe, executive director of Walk San Francisco, a pedestrian advocacy group, said she hoped the new parking app would lead to fewer accidents.
“It’s an innovative idea,” she said. “The safe way for people to use the device is for them to pull over, which they know they should do. The question is whether they will.”
But Ms. Soltani, the TV reporter, said using the app would probably join the group of activities already performed by drivers.
“We’re already looking at Google Maps and Facebook on the phone while we drive,” she said. “Aren’t we always looking at something on our phone, or changing the radio, or drinking coffee? You’re always slightly distracted when you’re driving.”
【小题1】What is the phone app mentioned in the text mainly aimed at?
| A．Making full use of the parking spots. |
| B．Making the traffic flow smoothly. |
| C．Preventing traffic accidents. |
| D．Benefiting iPhone users. |
| A．don’t consider the app distracting |
| B．advise drivers to park cars slowly |
| C．are aware of the app’s disadvantages |
| D．believe more parking spots are needed |
| A．Sensors"computers"app. | B．App"computers"sensors. |
| C．Sensors"app"computers. | D．Computers"app"sensors. |
| A．is a bit slow in reacting |
| B．hasn’t been put into service |
| C．was introduced several years ago |
| D．can’t be downloaded to all phones |
| A．Daniel Simons thinks the app convenient. |
| B．San Francisco will put more sensors into use. |
| C．Most drivers open the app once they start their cars. |
| D．Nathaniel Ford doesn’t doubt the practical use of the app. |

The government of Norway is planning to build an unusual storage center on an island in the Arctic Ocean. The place would be large enough to hold about two million seeds. The goal is to present all crops known to scientists. The British magazine New Scientist published details of the plan last month. The structure will be designed to protect the world’s food supply against nuclear war, climate change and other possible threats. It will be built in a mountain on the Norwegian island of Spitsbergen. The mountain is less than one thousand kilometers from the North Pole, the northernmost position on earth.
An international group called the Global Crop Diversity Trust is working on the project. The director of the group, Cary Fowler, spoke to New Scientist. He said the project would let the world rebuild agriculture if, in his word, “the worst came to the worst”. Norway is expected to start work next year. The project is expected to cost three million dollars. Workers will drill deep in the side of a sandstone mountain. Temperatures in the area never rise above 0ºC. The seeds will be protected behind walls a meter thick and high-security door.
The magazine report says the collection will represent the products of ten thousand years of farming. Most of the seeds at first will come from collections at seed banks in Africa, Asia and Latin America. To last a long time, seeds need to be kept in very low temperatures. Workers will not be present all the time. But they plan to replace the air inside the storage space each winter. Winter temperatures on the island are about eighteen degrees below 0ºC. The cold weather would protect the seeds even if the air could not be replaced.
Mr. Fowler says the proposed structure will be the world’s most reliable gene bank. He says the plant seeds would only be used when all other seeds are gone for some reason. Norway first proposed the idea in the 1980s. But security concerns delayed the plan. At that time, the Soviet Union was meeting in Rome of the Food and Agriculture Organization.
【小题1】The project is meant to ______.
| A．increase the world’s food output in the future |
| B．carry out some scientific experiments on plant genes |
| C．protect crop seeds from dying out in case of possible disasters |
| D．build an exhibition centre of the world’s plant seeds |
| A．The government of Norway will perform the project alone. |
| B．Seeds to be collected there were produced ten thousands years ago. |
| C．Spitsbergen is chosen because it is free of the threat unclear war forever. |
| D．Temperature is a major consideration when choosing the storage place. |
| A．People will get newly-developed seeds from the center every year. |
| B．The storage center will greatly promote world agriculture |
| C．Norway had meant to build the storage centre about 30 years before. |
| D．There haven’t been any seed storage centers in the world before. |
| A．The Best Place to Store Seeds |
| B．Noah’s Ark（诺亚方舟）of Plant Seeds in Plan |
| C．Concerns of World Food Supply |
| D．A New Way to Feed the World |

“I stepped out and was flabbergasted,” local journalist Bahram Baloch told the BBC. “I could see this gray, dome-shaped (圆顶形的) body in the distance, like a giant whale swimming near the surface. Hundreds of people had gathered to watch it in disbelief.”
This island has become a global curiosity. How was it formed in just a few minutes?
As you might already know, many islands in the sea are formed by volcanoes. There are numerous volcanoes under the sea. As the hot lava erupts and cools down, it piles up and forms the shape of a mountain. When the mountain “grows” to higher than the sea level, the part that’s above the water is what we call an “island”.
This is how the island was formed after the Pakistan earthquake, except that instead of a regular volcano, it was a “mud volcano” that brought about this island. Lava is not the only thing that’s locked under the Earth’s crust — there is also gas. When an earthquake happens and breaks part of the crust, the gas is released at an extremely high speed, pushing mud up to the surface, according to National Geographic.
But only earthquakes that are extremely powerful can cause mud volcanoes to push up enough mud to produce islands — and this 7.7-magnitude earthquake in Pakistan was strong enough. The island is about 20 meters high, up to about 90 meters wide and 30 meters long, nearly the size of a soccer field.
In fact, mud volcano islands aren’t new. This is the fourth island of this kind in the region since 1945. But those islands usually didn’t last long.
“It will probably be gone within a couple of months,” said Bill Barnhart, a researcher with the US Geological Survey. After all, “it’s just a big pile of mud that was on the seafloor that got pushed up”.
【小题1】What is the article mainly about?
| A．The disastrous effects of coastal earthquakes. |
| B．The difference between mud volcanoes and regular volcanoes. |
| C．How islands are formed by mud volcanoes. |
| D．The great natural wonders of Pakistan. |
| A．surprised | B．disappointed | C．worried | D．curious |
| A．the new island near the coast of Pakistan actually took a few months to form |
| B．scientists still know little about different types of volcanoes |
| C．another earthquake is likely to happen in Pakistan within a couple of months |
| D．not all volcanoes change the geological appearance of the Earth |
| A．are quite difficult to locate |
| B．usually disappear after a short period of time |
| C．are formed by hot lava from volcanoes |
| D．used to be part of the Earth’s crust |

March 22, 20II---Most restaurants in the United States offer their customers a glass of tap water at no charge with their meal, but this week many restaurants are asking dinners to pay a dollar, or more, for a glass of water. Cards on their tables explain that this small amount helps bring clean water to children around the world. It’s called the UNICEF Tap Project.
“UNICEF’s Tap Project is really all about bringing attention to the fact that over 900 million people around the globe do not have access to good, clean, healthy drinking water,” says Cary Stem, who heads the US Fund for UNICEF. She adds that water-borne illness is the second-highest cause of preventable childhood death in the world.
“Each and every day approximately 4,100 children die just because they don’t have that access - 4,100 every single day.”
The public service campaign encourages people to help change that statistic with a simple, affordable action: paying a dollar to get a glass of tap water at a restaurant.
“One dollar buys enough good, clean water for a child for 40 days,” Stem says.
“The tap project has expanded since it began five years ago with 300 restaurants in New York City. This year, Stem says, about 3,000 restaurants across the country are participating in the campaign. We raised about $2.5 million over the last five years of this campaign,” says Stem. “Last year, we raised over $1 million for the first time. This year we’re hoping to top that.”
Stem credits the continued success of the campaign to an army of volunteers who support the tap project and raise money in their communities.
The UNICEF Tap Project is promoting its efforts with a simple motto: when you take water, give water. Currently, UNICEF works in more than 100 countries around the world to improve access to safe water and sanitation facilities in schools and communities.
Stem hopes that, by participating in the project, more Americans will realize that what they often take for granted is a precious and scarce resource in many other parts of the world.
【小题1】Restaurants began to charge for tap water to _______.
| A．increase their profit |
| B．urge customers to save water |
| C．raise people’s awareness of the world water problem |
| D．collect money for those without access to safe water |
| A．began in New York City |
| B．was started by volunteers |
| C．is hoping to collect $2.5 million this year |
| D．provides help for 1,000 countries in the world |
| A．the Tap Project began in 2006 |
| B．America suffers a serious problem |

Prince William and the Duchess of Cambridge's new son will be named George Alexander Louis, the royal family says. A statement from William and Catherine's settlement Kensington Palace said the baby, third in line to the throne(王位), would be known as His Royal Highness Prince George of Cambridge.
On Wednesday the royal couple took their son to Catherine's parents' house in Berkshire, following a half-hour visit by the Queen. All three names had been among the favourites listed by British bookmakers and the announcement was relatively quick by royal standards. It took a month for the name ofPrince Charles, the heir to the throne, to be announced, and a week for William, his eldest son.
George has been the name of six British kings. The last, George VI, was the father of Queen Elizabeth II and reigned from 1936 to 1952. Alexandra, the female form of Alexander, is one of the Queen's middle names and was also the name of the Queen mate of King Edward VII at the start of the last century. Louis is one of William's middle names and was the given name of Prince Charles's tutor and great-uncle Louis Mountbatten, who was murdered by the IRA in 1979.
The choice of name, relatively short by royal standards, does not necessarily mean the baby will eventually become King George VII. The Queen's father was named Albert, but chose to be crowned as George VI.
"It's interesting that they chose to go with just three names," historian Suzannah Lipscomb told Sky News. "It's almost as if the royal family is coming down with ordinary people, who tend to have fewer middle names than monarchs(君主).It is a name that none can find any problems with. George itself can't be shortened in any obvious offensive way. They've probably gone for something that is safe."
【小题1】Which of the following statements can best sum up the passage ?
| A．New royal baby named George Alexander Louis |
| B．The royal couple gave birth to their eldest son. |
| C．The choice of name was interesting and complicated . |
| D．The new baby, third in line to the throne . |
| A．Catherine | B．George. | C．Charles | D．William |
| A．Prince Charles was the third heir to the British throne. |
| B．George Alexander Louis was the third heir to the British throne. |
| C．The announcement of the new loyal baby’s name is slow by royal standards. |
| D．All three names , George Alexander Louis, were unpopular with British bookmakers. |
| A．resign | B．boom | C．govern | D．retire |
| A．the name of an ordinary person is simple but meaningful . |
| B．George itself can't be simplified in any obvious offensive way. |
| C．a monarch or a prince has usually more names in the middle than the ordinary people. |
| D．a person with more middle names must be a monarch or a prince . |
