When coal is burned in a boiler, two kinds of ash by-products are produced: a heavy bottom ash and a fine-as-powder fly ash. About 10 to 15 percent of the coal by-product is bottom ash which is used like sand on streets and highways covered with ice, and also on highways as paving material.
It is the fly ash, however, that is receiving much attention. Once considered a waste, fly ash is now regarded as a natural resource in the United States. It can be placed in some lower places, where it is compacted and covered with soil, for the seeds of various grasses and plants to be placed in the soil to make the land productive.
Fly ash may be added to concrete to build roads and other kinds of buildings, taking the place of the cement up to 20 percent. As a by-product of burned coal, fly ash requires no extra energy to be produced, while cement production requires great amounts of energy.
Besides, the technology is able to take out some useful minerals from the fly ash, which is still a very expensive process today. But the time may come when it is cheaper to take out these products from ash than to mine new supplies. The bottom ash can be put on icy streets________.
| A．in order to rebuild them | B． in order to make them colourful |
| C．so that people can walk on them | D．so that cars can run faster |

| B． Fly ash is made while producing cement. |
| C．It takes less energy to produce fly ash than cement. |

Somali pirates(海盗) robbed three Thai fishing ships with 77 sailors on board nearly l, 200 Miles off the Somali coast, the farthest-off-shore attack to date, an officer said Tuesday.
Pirates have gone farther south and east in answer to increased patrols(巡逻)by warships off the Somali shore. The robbing of the three ships Sunday was about 600 miles outside the normal operation area for the international force, said a spokesman.
The spokesman said the attack so far out at sea was a clear sign that the international patrols against pirates were having a “marked effect on pirate activity in the area”.
“Once they start attacking that far out, you’re not even really talking about the Somali basin or areas of water that have any connection with Somalia,” said an officer, Roger Middleton. “Once you’re that far out, it's just the Indian Ocean, and it means you’re looking at trade going from the Gulf to Asia, from Asia to South Africa. ”
“This is the farthest robbing to date. They are now operating near the Maldives and India,” said another officer.
The three ships--the MV Prantalay 11, 12, and l 4—had 77 members on board in total. All of them are Thai, the spokesman said. Before the Sunday robbing, pirates held l l ships and 228 sailors.
Pirates have increased attacks over the past year in hopes. of catching more dollar payments. Because of increased patrols and defenses on board ships, the success rate(率)has gone down, though the number of successful attacks has stayed the same year over year.The pirate attack reported in the text happened __________.
| A．far out in the Indian Ocean |
| B．in the normal patrol area |
| C．near the Somali, coast |
| D．in the south of Africa |

| A．More goods on board are lost. |
| B．Pirate attacks happen in a larger area now. |
| C．The number of attacks has stayed the same these years. |
| D．Pirate attacks are as serious as before along the Somali coast. |
Which is true about the warship patrols according to the text?
| A．The patrols are of little effect. |
| B．The patrols are more difficult. |
| C．More patrols are quite necessary even in Asia. |
| D．The patrols only drive the pirates to other areas. |
How many sailors were held by the pirates up to the time of the report?

When I first got an email account ten years ago, I received communications only from family, friends, and colleagues. Now it seems that every time I check my e-mail, I have an endless series of advertisement and other correspondence that do not interest the at all. If we want e-mail to continue to be useful, we need special laws that make spamming(发送垃圾邮件) a crime.
If lawmakers do not do something soon to prohibit spam, the problem will certainly get much worse. Computer programs allow spammers to spend hundreds of millions of e-mails almost instantly. As more and more advertisers turn to spam to sell their products, individual e-mail boxes are often flooded with spam e-mails. Would people continue to use e-mail if they had to deal with an annoying amount of spam each time?
This problem is troubling for individuals and companies as well. Many spam emails contain computer viruses that can shut down the entire network of a company. Companies rely on e-mail on for their employees to communicate with each other. Spam frequently causes failures in their local communications networks, and their employees are thus unable to communicate effectively. Such a situation results in a loss of productivity and requires companies to repeatedly repair their networks. These computer problems raise production costs of companies, which are, in the end, passed on to the consumer.
For these reasons, I believe that lawmakers need to legislate (立法) against spam. Spammers should be fined, and perhaps sent to prison if they continue to disturb people. E-mail is a tool which helps people all over the world to communicate conveniently, but spam is destroying this convenience.What does the underlined word “correspondence” in the Paragraph 1 probably mean?
| A．messages | B．ideas | C．connections | D．programs |
According to the text, what is the major cause of the flooding spam?
| A．Companies rely on e-mail for communications. |
| B．More people in the world communicate by e-mail. |
| C．Many computer viruses contain spam e-mail. |
| D．More advertisers begin to promote sales through spam. |
According to Paragraph 3,who is the final victim of spam?
| A．The business | B．The advertiser |
| C．The employee | D．The consumer |
What is the purpose of the text?
| A．To inform | B．To educate | C．To persuade | D．To instruct |
Many cities have subways and underground public transportation to take locals and tourists alike rapidly around the city．However, there’s something different about riding a London subway．It may not look different, but the historical value of one of England’s most popular forms of transportation is enough to make riding the subway a must when visiting London．With a little under 300 different stations, the subway can take you almost anywhere you need to go．
Riding a London subway, a person from other countries will notice one major difference: in London, people do not look at each other．In fact, eye contact is avoided at all times．That’s not rudeness―people are just too busy to bother looking．
Busy doing what, you ask? Well, they’re certainly not using the time for a moment of quiet thinking．Nor are they reading a book．New technology has replaced quiet habits．Today the only acceptable form of book on the London underground is an e-book．
Apple must earn a fortune from London commuters（使用月票上下班者）．Since the launch of the iPhone in 2007, over 40,000―yes, that’s 40,000 “apps” have been designed．
Commuters love them because they are the perfect time-fillers．One “app”, called iShoot, is a game that features tanks．Another one, Tube Exits, tells passengers where to sit on the train to be closest to the exit of their destination．iSteam clouds the iPhone screen when you breathe into the microphone．You can then write in the “steam” on your phone screen．
For those without an iPhone, another Apple product, the iPod, may be the distraction（消遣）of choice．It’s not just teenagers who “plug in” to their music－iPods are a popular way to pass the time for all ages．
And if games, e-books and music aren’t enough to keep you occupied, then perhaps you would prefer a film? The development of palm DVD technology means many commuters watch their favorite TV shows or films on the way to work．With all these distractions, it’s amazing that people still remember to get off the train．Those who want to save time to reach where they go can download ______ to their iPhones．
| A．iShoot | B．iPod | C．iSteam | D．Tube Exits |
People in London do not make eye contact on the subway because ______．
| A．they are going to work and have no time to communicate with each other |
| B．they are busy playing games, reading e-books, listening to music or watching film |
| C．they feel sleepy because of getting up early |
| D．they love reading books and do not want to be disturbed |
The underlined word “apps” in the fourth paragraph means ______．
| A．computers |
| B．fortune from London commuters |
| C．computer companies |
| D．programs downloaded for the iPhone |
Which word best describes the writer’s attitude towards commuters’ behaviors ?
| A．for | B．neutral | C．against | D．hateful |
The main idea of the passage is that ______．
| A．London commuters are unfriendly to strangers |

Susan Sontag (1933 ------ 2004) was one of the most noticeable figures in the world of literature. For more than 40 years she made it morally necessary to know everything----- to read every book worth reading, to see every movie worth seeing. When she was still in her early 30s, publishing essays in such important magazines as Partisan Review, she appeared as the symbol of American culture life, trying hard to follow every new development in literature, film and art. With great effort and serious judgment, Sontag walked at the latest edges of world culture.
Seriousness was one of Sontag’s lifelong watchwords (格言), but at a time when the barriers between the well-educated and the poorly-educated were obvious, she argued for a true openness to the pleasure of pop culture. In Notes Camp, the 1964 essay that first made her name, she explained what was then a little-known set of difficult understandings, through which she could not have been more famous. Notes on Camp, she wrote, represents “a victory of ‘form’ over ‘content’, ‘beauty’ over ‘morals’”.
By conviction she was a sensualist (感觉论者), but by nature she was a moralist, and in the works she published in the 1970s and 1980s, it was the latter side of her that came forward. In Illness as Metaphor ------published in 1978, after she suffered cancer ------ she argued against the idea that cancer was somehow a special problem of repressed (被压抑的) personalities, a concept that effectively blamed the victim for the disease. In fact, re-examining old positions was her lifelong habit.
In America, her story of a 19th century Polish actress who set up a perfect society in California, won the National Book Award in 2000. But it was as a tireless, all-purpose cultural view that she made her lasting fame.
“Sometimes,” she once said, “I feel that, in the end, all I am really defending… is the idea of seriousness, of true seriousness.” And in the end, she made us take it seriously too.It is implied but not stated in the first paragraph that Sontag _________.
| A．was a symbol of American cultural life |
| B．developed world literature, film and art |

America is a mobile society. Friendships between Americans can be close and real, yet disappear soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while — then no more. If the same two people meet again by chance, even years later, they pick up the friendship. This can be quite difficult for us Chinese to understand, because friendships between us flower more slowly but then may become lifelong feelings, extending (延伸) sometimes deeply into both families. Americans are ready to receive us foreigners at their homes, share their holidays, and their home life. They will enjoy welcoming us and be pleased if we accept their hospitality (好客) easily. Another difficult point for us Chinese to understand Americans is that although they include us warmly in their personal everyday lives, they don’t show their politeness to us if it requires a great deal of time. This is usually the opposite of the practice in our country where we may be generous with our time. Sometimes, we, as hosts, will appear at airports even in the middle of the night to meet a friend. We may take days off to act as guides to our foreign friends. The Americans, however, express their welcome usually at homes, but truly can not manage the time to do a great deal with a visitor outside their daily routine. They will probably expect us to get ourselves from the airport to our own hotel by bus. And they expect that we will phone them from there. Once we arrive at their homes, the welcome will be full, warm and real. We will find ourselves treated hospitably. For the Americans, it is often considered more friendly to invite a friend to their homes than to go to restaurants, except for purely business matters. So accept their hospitality at home!The writer of this passage must be ______.
| A．an American | B．a Chinese | C．a professor | D．a student |

From the last two paragraphs we can learn that when we arrive in America to visit an American friend, we will probably be ______.
| A．warmly welcomed at the airport |
| B．offered a ride to his home |
| C．treated hospitably at his home |
| D．treated to dinner in a restaurant |
