It was the latest sign of the effects of desertification: Overgrazing, deforestation, urban sprawl(无计划地扩展) and drought have expanded deserts in the country"s north and west. The shifting sands have gradually moved onto populated areas and worsened sandstorms that strike cities, particularly in the spring.
Winds blowing from the northwest have been sweeping sand across the country since Saturday, affecting Xinjiang in the far west all the way to Beijing in the country"s east. The sand and dust were carried to parts of southern China and even to cities in Taiwan, 1600 miles (2600 kilometers) away from Inner Mongolia where much of the pollution originated.
The sandstorm in Taiwan, an island 100 miles (160 kilometers) away from the mainland, forced people to cover their faces to avoid breathing in the grit(砂砾) that can cause chest discomfort and respiratory problems even in healthy people. Drivers complained their cars were covered in a layer of black soot in just 10 minutes.
In Hong Kong, environmental protection officials said pollution levels were climbing as the sandstorm moved south. Twenty elderly people sought medical assistance for shortness of breath, Hong Kong"s radio RTHK reported.
The latest sandstorm was expected to hit South Korea on Tuesday, said Kim Seung-bum of the Korea Meteorological Administration. The sandstorm that raked(掠过) across China over the weekend caused the worst "yellow dust" haze in South Korea since 2005, and authorities issued a rare nationwide dust advisory.
Grit from Chinese sandstorms has been found to travel as far as the western United States.
China"s Central Meteorological Station urged people to close doors and windows, and cover their faces with masks or scarves when going outside. Sensitive electronic and mechanical equipment should be sealed off, the station said in a warning posted Monday on its Web site.
State television"s noon newscast showed the tourist city of Hangzhou on the eastern coast, where graceful bridges and waterside pagodas were hidden in a mix of sand and other pollution. In Beijing, residents and tourists with faces covered scurried along sidewalks to minimize exposure to the pollution.
A massive sandstorm hit Beijing in 2006, when winds dumped about 300,000 tons of sand on the capital.

The first thing to remember is that you must be willing to learn It doesn"t mean that yep must always like the subject. It does mean, however, that you must be willing to do whatever is necessary to learn Try to understand why it is important and how it will help you now arid later to do and learn other things. Knowing mathematics facts will be useful in your whole life. Knowing how to spell makes any kind of writing easier. Sometimes the subject that you think is going to be uninteresting will be exciting when you begin to work at it and understand it more clearly. Learning things can be fun if you are willing to work with them
Here"s some advice for you; have a certain time each day and a quiet place with good lighting for study, so that you can concentrate on your study without interruptions; have eve- rything ready before you sit down to study, a dictionary, paper, a pen and books; be sure you understand what you should learn before you start；read carefully and pay special attention to the most important things；when memorizing, first find out the main parts and then recite the whole thing，check your homework after you finish it; never forget the importance of review and preview.
Don"t try to spend a lot of time researching learning methods. There are many students who know many good learning methods but don"t study well. They forget that the most useful learning method is to study hard

The laws of economics suggest that Wal-Mart, with 5, 200 stores worldwide, influences everything including the price of all kinds of goods. It throws its weight behind environmental responsibility, and the impact could be amazing. “One little change in product packaging could save 1, 500 trees,” says Wal-Mart CEO Lee Scott．“If everybody saves 1, 500 trees or 50 barrels of oil, at the end of the day you have made a huge difference.”
Scott wants Wal-Mart to do its part too. He has promised to cut the existing greenhouse-gas emissions（排放）over the next few years and promised to construct new stores that are more efficient. He wants Wal-Mart’s fleet of more than 7, 000 trucks to get twice as many miles per gallon by 2015. Factories that show Wal-Mart they’re cutting air pollution will get preferential treatment in the supply chain. Wal-Mart says it’s working with consumer-product manufacturers to reduce their packaging and will reward them if they do so.
Some people may doubt it is a bid to attract attention from Wal-Mart’s controversial labor and health-insurance practices. But it’s not just window dressing, because Wal-Mart sees profits in going green. Scott says, “This is a business philosophy, not a social philosophy. We don’t go where we don’t think there’s a great interest in change.”
Like Bill Gates, who started his charitable foundation, Scott happens to be promoting Wal-Mart’s image at a time when his company’s reputation is declining. He acknowledges that he launched the plan partly to shield （保护）Wal-Mart from bad press about its contribution to global warming. “By doing what we’re doing today, we avoid the headline risks that are going to come for people who did not do anything,” he says. “At some point businesses will be held responsible for the action they take.” Meanwhile, should Wal-Mart succeed at shrinking its environmental footprint and lowering prices for green products, both the planet and the company will profit.
小题1:We can infer from the passage that ______.
| A．Lee Scott is Wal-Mart’s CEO |
| B．there are 5, 200 stores in the world |
| C．Wal-Mart has a great influence on the world market |
| D．Wal-Mart has more than 7, 000 trucks all over the world |
| A．Wal-Mart predicts huge profits in its green activity. |
| B．Wal-Mart’s green activity is just window dressing. |
| C．Wal-Mart aims to solve its health-insurance practices. |
| D．Wal-Mart doesn’t have any social responsibility at all. |
| A．Reduce air pollution in its present stores. |
| B．Give favorable treatment to its consumers. |
| C．Ask the factories to reduce their packaging. |
| D．Demand the fleet of trucks to use more fuel than before. |
| A．Provide the background of the green plan. |
| B．Stress the purpose of Wal-Mart’s green plan. |
| C．Present the risk that Wal-Mart is facing nowadays. |
| D．Analyze the similarity between Bill Gates and Scott. |
The World Tourism Organization claims that the industry looked after 592 million travelers last year who spent $423 billion, and of all the types of tourism, ecotourism seems to be the fastest growing. By the broadest measure -- a trip with some sort of nature or wilderness element -- ecotourism already accounts for perhaps a third of these travelers. On a stricter definition favored by the Ecotourism Society, it is “responsible travel that preserves natural environments and keeps up the well-being of local people,” which accounts for no more than 5% of tourism.
Ideally, ecotourism helps both people and nature. Before the disastrous civil war, Rwanda’s Mountain Gorilla Project was one such model. Visits to the gorillas were limited, local guides ensured good behavior or on the part of the humans, and the high admission charge - $170 a day -- paid for salaries and presentation of the gorillas’ living areas. As this made the gorillas worth more alive than dead, poaching (偷猎) decreased. As another example, preservation Cooperation, Africa’s largest ecotour operator, uses only local labor, buys products 5om local farmers, and supports building projects: such as clinics and schools. This contribution to social advance is also good business sense. Projects from which local people benefit directly are less likely to be affected by poaching and theft.
Ecotourism’s biggest problem is labeling. Going on an eco-tour is no guarantee of good ecology. So far, only Australia has an official system to grade tour operators and tourist attractions on the basis of their “greenness”. Another issue is how eco-tourists damage the environment. Dolphin-feeding, for instance, is innocent and enjoyable, but after too many free meals, the dolphins forget how to catch their own dinners.
Keeping prices high is one way to limit enthusiasm. But measuring the effect of ecotourism on human environments is trickier. It is common, for villagers to see ecotourism as a source of new income. Hence, the very tourists who venture in search of traditional cultures end up breaking them up. As ecotourism becomes more popular, it will finally threaten the very things that are good for business.
小题1:According to the passage, ecotourism may _________.
| A．harm its own purpose by becoming too popular |
| B．save the environment by becoming more popular |
| C．harm its own purpose by becoming less popular |
| D．save the environment by becoming less popular |
| A．has no single, clear definition that would satisfy everybody |
| B．has expanded less rapidly than other types of tourism |
| C．claims that no comfortable hotels should be used by tourists |
| D．most often has a negative effect on local culture |
| A．tourists were free to visit the gorillas whenever they wanted to |
| B．local people’s attitudes toward animals were not affected |
| C．the gorillas were protected from both tourists and local people |
| D．the gorillas’ living area was modernized because of the high admission |
| A．Rwanda’s Mountain Gorilla Project | B．Preservation Corporation |
| C．Australia’s grading system | D．Dolphin-feeding |
The hard, parrot-like beak（喙）of an octopus is not used for attacking deep-sea divers, but for cutting open shellfish. Indeed, the octopus possesses such a tiny throat that it cannot swallow large pieces of meat. Instead, it feeds by pouring digestive juices into its victims, and then sucking up the soupy remains. A shellfish that finds itself in the grasp of an octopus has only a short time to live. But human beings are perfectly safe. Still, people rarely care to go close enough to these careful creatures to get a good look at them.

| A．the horrors of the octopus |
| B．the largest octopus in the world |
| C．octopi and their behavior |
| D．the octopus’s deadly hunting method |
| A．people have unreasonable fears about the octopus |
| B．the octopus is not interested in human beings |
| C．the octopus is afraid of human beings |
| D．the octopus is a very cruel sea animal |
| A．Octopi. | B．Shellfish. | C．Fish. | D．The victims. |
| A．attacking deep-sea divers | B．cutting up large pieces of meat |
| C．cutting open its victims | D．defending itself |
| A．the octopus is not dangerous to man |

| D．things described in movies are not to be believed |
A“paperless classroom”is what more and more schools are trying to achieve.Students don"t do any handwriting in this class. Instead, they use palm (手掌) size, or specially-designed computers. The teacher downloads texts from Internet libraries and sends them to every student"s personal computer.
Having computers also means that students can use the Web. They can look up information on any subject they"re studying from math to social science.
High school teacher Judy Herrell in Florida, US, described how her class used the Web to learn about the war in Afghanistan (阿富汗) over one year ago.
"We could touch every side of the country through different sites? from the forest to refugee camps (难民营)," she said. "Using a book that"s three or four years old is impossible."
And exams can go online too. At a high school in Tennessee, US, students take tests on their own computers. The teacher records the grades on the network for everyone to see and then copies them to his own electronic grade book.
A paperless classroom is a big step towards reducing the waste of paper. High school teacher Stephanie Sorrell in Kentucky, US, said she used to give about 900 pieces of paper each week to each student.
"Think about the money and trees we could save with the computers," she said.
But, with all this technology, there"s always the risk that the machines will break down. So, in case of a power failure or technical problems, paper textbooks are still widely available for these hi-tech students.
小题1:What does the part of the last sentence in the first paragraph, “run out of ink at the critical moment”, mean?

| D．the Web better than the textbooks, can give the latest and comprehensive (全面的) information |
| A．students | B．teachers | C．trees | D．computers |
| A．Break into pieces. | B．Stop working |
