Scientists have found what look like caves on Mars, and say they could be protecting life from the planet’s terrible environment.
The first caves discovered beyond the Earth appear as seven mysterious black dots on the pictures sent back by NASA’s Mars Odyssey orbiter. Each as large as a football field, they may be openings into natural caves below the Martian surface.
“If there is life on Mars, there is a good chance you’d find it in caves,” said Jut Wynne, one of the researchers who noticed the features while working on a US Geological Survey Mars Cave Detection Program.
Jonathan Clarke, a geologist with the Mars Society of Australia, yesterday described the discovery as exciting.
One photo taken at night by an infrared imager(红外线成像器) showed one hole to be unusually warm, suggesting hot air trapped during the day is flowing out.
“I said: ‘Wow, that’s a cave’.” Dr. Clarke said excitedly. “People have been looking for these for a long time; now we have found them.”
He agreed such caves would be perfect places to hunt for life escaping from the bitterly cold, radiation-soaked(充满辐射的), dry surface.
“Tiny drops of water could collect inside,” he said. “If there are gases coming out, they could provide energy for a whole range of bacteria. A cave is also a protection from radiation; the surface of Mars is exposed to high levels of space radiation.”
The caves probably formed when tube-shaped lave flows(管状岩浆流) spread across the planet long ago. The outside of the tubes cooled, forming solid walls, while something hotter inside allowed the remaining have to flow out, forming caves.

The US navy boarded an apparent pirate (海盗) ship in the Indian Ocean and kept 26 men for questioning, the navy said Sunday.
The 16 Indians and 10 Somali men were aboard a traditional dhow (单桅三角帆船) that was chased and seized Saturday by the US guided missile destroyer (驱逐舰) USS Winston Churchill, said Lieut I.eslie Hull-Ryde of US Naval Forces Central Command in Bahrain.
The dhow stopped fleeing after the Churchill twice fired warning shots during the chase, which continued no more than 87 kilometers off the coast of Somalia, the navy said. US sailors boarded the dhow and seized a cache (暗窖) of small arms.
The dhow's crew and passengers were being questioned Sunday aboard tim Churchill to determine which were pirates and which were lawful crew members, Hull-Ryde said.
Sailors aboard the dhow told navy investigators that pirates hijacked (抢劫) the ship six days ago near Mogadishu and afterwards used it to stage pirate attacks on merchant ships.
The Churchill is part of a muhinational task force patrolling (巡逻) the western Indian Ocean and Horn of Africa region to thwart (阻止) terrorist activity and other lawlessness during the US-led war in Iraq.
The Navy said it captured the dhow in response to a report from the International Maritime (海事的) Bureau in Kuala Lumpur on Friday that said pirates had fired on the MV Delta Ranger, a Bahamian-flagged bulk carrier (货轮) that was passing some 320 kilometres off the central eastern coast of Somalia.
Hull-Ryde said the navy was still investigating the incident and would discuss with international authorities what to do with the men kept aboard the Churchill.

A. Among them were both lawful and lawless members.
B. Their ship was stopped by the police in the African region.
C. They are all from India.
D. They are pirates attacking merchant ships.
73. "Churchill" in the text is _______.

C. a military ship D. the title of a military action
74. Which of the following correctly describes how the dhow was captured?
a.Warning shots were fired b. Merchant ships were attacked by pirates.
c. The dhow was hijacked, d. US sailors boarded the dhow.

75. How did the US navy find the dhow?

Computers are helpful because they offer a wide range of functions and services that are not available anywhere else. There are four main uses: word processing, Internet/ communications, digital video/ audio composition, and desktop publishing.
The word processing capabilities of computers are amazing. They can automatically correct your spelling and grammar mistakes. The cutting and pasting features are incredibly simple and very useful for revision. Having a digital backup is an added benefit. All of these things help writers get the job done. With desktop publishing, you can create page layouts（页面布局）for entire books on your home computer.
The Internet is one of the greatest inventions created by humans. It is a huge network of computers, each with the ability to contact any of the others. Vast amounts of information can be found on the Internet. It is the ultimate form of media, a combination of newspaper, radio and television. Using the Internet, any two people anywhere can communicate for free, whether it is by text or voice. New uses are being found for the Internet every day.
Audio/ video editing and composition have been made much easier by computers. Cutting and pasting no longer involve using scissors and tape on large reels of film. It no longer costs thousands of dollars of equipment to make a film or to compose music. Now musicians can compose their own songs and publish them without having to obtain a record contract. Film-makers can produce work from their own homes. Anybody who owns a computer can now enter the field of media production.
Internet/ communications, digital video and audio composition, and desktop publishing are features only offered on computers. With the aid of computers, humankind is entering a new era of civilization.

Women turn to online shopping
Women have jumped ahead of men for the first time in using the Internet to do their holiday shopping, according to a study published last week in the US. For years men have been more likely to shop on the Internet than women, but during the 2004 holiday season 58 percent of those making online purchases were women. “It shows how mainstream the Internet is becoming,” said Lee Rainie, director of the Pew Internet and American Life Project group, which carried out the study. Rainie said it was only a matter of time before women shoppers caught up with men. This is because women traditionally make decisions about spending. Users were more likely to shop online to save time . Internet users between the ages 18 and 29 were responsible for some of the most dramatic increase in the online gift-buying population this time around. However, three-quarters of the US Internet users did not buy holiday gifts online in 2004. They worried about credit card security, or just compared online prices with off-line prices, then dashed off to the shops to get the best deals. “But even if shoppers don’t buy online, websites are becoming promotion tools for stores,” said Dan Hess, vice president of ComScore Networks Inc. Hess said that actually most stores’ websites can make customers fully believe the security of their credit card numbers. And most are able to ensure that gifts arrive on time“It’s all about making the shopping experience more efficient, more reliable and more comfortable.” Hess said.
60. Which of the following statements is true?There were fewer women online shoppers than men in 2004. Most of the Internet users between the ages of 18 and 29 are women. People in the US were more likely to buy gifts online. More women shopped online than men in 2004.
61. From the passage we can infer that ______________. men usually decide how to spend money in the familywomen usually decide what to buy in the familythe Internet is used in all the shopsmore and more shops will sell their goods online
62. According to Dan Hess , shopping online ______________. A. is unsafe B. is convenient C. is a waste of money D. is cheaper
63. What can we know from the passage?
A. American people only gifts in holidays.
B. Shopping online is fun for women.
C. Shopping off-line provides better serve.
D. Young people like to do gift-shopping online.

Boston ― thieves dressed as police entered a museum early Sunday and stole 11 paintings, including major works by Rembrandt, Dagas, Manet, and Vermerr, FBI and the museum officials said.
The first judgement placed value of at least $100 million on the works stolen from the Isabella Teward Gardener Museum, said Boston police spokesman Jim Tordan.
The judgement was a loose（粗略的） one because the paintings have not been sold in nearly a century.
But art experts said such well-known works could not be sold in nearly a century, authorities said.
“It was not discovered until the cleaning people did some cleaning at 3 a.m.” said Paul Cavangah, special FBI agent in Boston.
“This is one of those thefts(盗窃)where people actually spent some time researching and took specific things,” he said.
He said the investigation(调查) would not be limited to the U.S.
William Bobinson of Harvard University’s Foggel Museum, called the objects stolen “major works”.
