It is known to us that computer users are being warned by industry experts to pay attention to secret codes which could be used to record their conversation.

E-mails, screen savers, and electronic greeting cards can carry a secret code which is able to turn on the computer’s microphone, make a recording, and forward it to someone else without the user’s knowledge.

In fact any attachments (附件) sent to a computer, whether it is a game of Space Invaders, or a moving picture, can possibly be used to spy (窥探).

Experts say people should always think twice about opening attachments because --- although not common --- bugging (窃听) by computer can and has been done.

Bill Lyons, head of the Internet Security Company Finjan, said, “People in the army have tested this and you can be sure, if people in general are aware of it, then computer hackers (黑客) are aware of it. The frightening thing is that there are tools on the Internet which people, using a simple search method, can find, and which will enable them to attach this dangerous code to simple attachments.”

1.What is the advice given in the passage?

A. Use secret codes to record other people’s conversation.

B. Be careful when opening an attachment.

C. Never open any attachments.

D. Never use secret codes.

2.What worries the experts is that ___ .

A. nobody seems to believe such things

B. nobody knows the danger of the code

C. tools can easily be used to tie dangerous codes to e-mails

D. effective ways can never be found to deal with the problem.

The most famous statue-the Sphinx in Egypt has been damaged. The experts are trying to find out the cause to protect it.
　 As we all know, the Sphinx has the body of a lion and the face of a man. It was cut from limestone(石灰石) near Egypt's pyramids about 4, 500 years ago. Not long ago a large piece of stone fell from the Sphinx's right shoulder.
　 In order to protect the statue from more harm, a computer was placed on it to measure rainfall, wind speed and air temperature. The computer also measured the amount of water and air pollution, the direction of wind and the temperature of the statue itself. The effects of age, wind, water and pollution have greatly weakened the Sphinx. Sunlight, wind, water and pollution have been eroding the outside of the statue for centuries. The experts hope that the information from the computer will help protect it from more damage. They say the more they know about what is destroying the Sphinx, the more they can do to protect it.

1.What does this passage mainly tell us?

At 1,345 meters above sea level, Ben Nevis is not the world’s most difficult mountain to climb. But things get considerably tricky if instead of hiking shoes you put on a pair of 5-inch high heels, especially if you’re a guy. One English teenager recently proved that it was not impossible.

Ben Conway, a 19-year-old art student from London, recently began the challenge as a way to stand out in an application(申请) for a scholarship for the School of Communication Arts in Brixton. He started his unusual high-heel climb at 8 a. m., on June 27, and was joined by Callum MacKenzie Allen, a friend from his art foundation year, who videotaped the whole thing for a two-minute video that was used as his application project. The whole climb took five hours and wasn’t the smoothest experience.

Halfway up Ben Navis, one of his shoes broke, so he had to tape the shoes to his feet to make sure they stayed on. The weather didn’t make it easy for him either, as he claimed that it rained pretty much the whole time, and he had to go against 40 to 50 miles an hour winds. Due to these difficult conditions, Ben and his friend had to turn back after reaching 900 meters up the mountain.

Besides providing an art school application project, the high-heel climb also allowed the 19-year-old to raise some money for worthy causes(事业), like Sal’s Shoes, which provides footwear for barefoot children around the world.

“Raising money for charity brings happiness to people’s lives and if I can do something ridiculous and bring someone happiness, then that’s what it’s all about.” Ben said.

1.What can replace the underlined word “tricky” in Paragraph 1?

A. pleasant　　 B. boring.

C. difficult.　　 D. smooth.

2.Why did Allen videotape the high-heel climb for Ben?

A. To prove nothing is impossible.

B. To record a special experience.

C. To develop their friendship.

D. To help Ben’s application.

3.What does Paragraph 3 focus on?

A. The difficulties in the climb.

B. The climbing way.

C. The terrible weather.

D. The expected thing.

4.What can best describe Ben’s story?

A. Puzzling.　　 B. Encouraging.

C. Exciting.　　 D. Frightening.
