Today, ultrasonic(超声的) waves are being put to work in laboratories and factories. If an ultrasound generator is placed in a liquid, the waves move the liquid back and forth hundreds of thousands of times each second. This causes materials to mix quickly or to dissolve(使分解，使溶解) in liquids. Paint manufacturers(制造商) use ultrasound to do a better job of blending colors. The companies that make film for your camera find that mixing chemicals by the use of sound waves will produce a more sensitive film.

The new lightweight(轻量的) type of washing machine uses ultrasonic waves to get clothes clean. Its special ultrasound generator is put into a pail of soapy water containing the soiled clothes. The sound waves drive the soapy water back and forth through the cloth so fast that everything is soon clean. There is also a new kind of dishwasher that works in much the same way.

Ultrasonic waves can shake a liquid so fast that tiny holes form all through it. The liquid is actually torn apart by this action. Almost as soon as these holes are made, they fall together again. The result is a powerful pounding action. In the dairy industry this is used for the double purpose of making homogenized(使均匀，使匀质) milk and sterilizing(使无菌) it at the same time. If you look at some raw milk with a microscope, you find that it is made up of little drops of butter fat floating around in a watery liquid. In order to make milk easier to digest, these fat droplets(微粒) may be broken up by forcing the milk through very small openings. The result is called homogenized milk. When the ultrasonic method is used, the sound waves not only break up the droplets but also kill the germs in the milk by pounding them to pieces. (from www.nmet168.com)

B. Because the waves move the liquid so quickly that it can make materials mix quickly or dissolve in liquids.

C. Because they can mix chemicals by the use of sound waves.

2. What properties does ultrasound wave have?

A. Homogenizes and sterilizes the milk.   B. Mix materials and break droplets.

C. Kill germs and sterilize milk.          D. Move liquids quickly.

3. What exists in the raw milk?

A. Little drops of butter fat.       B. Small holes.

C. Fat droplets and germs.        D. Chemicals.

4. Where is ultrasound wave not used?

A. In the paint manufacture.                   B. In the shop mixing bread flour.

C. In the film-making company.       D. In the dairy industry.

Jonathan James looks like just another kid about to graduate from high school. But this 19-year-old Swede is anything but ordinary, from the computer in his parents’ home he helps the US Federal Bureau of Investigation(FBI) find out the world’s most wanted cyber criminals(网络犯罪分子).

Jonathan first made headlines when he and another Swede, Fredrik Bjoerck, found out the maker of the “Melissa” virus(病毒) in March 1999. He came to the aid of the FBI again on May 7, finding out the suspected(嫌疑的) sender of the dangerous “I LOVE YOU” virus. The suspect was caught in Manila on May 8.

Jonathan’s special skills are in hot demand as officials around the world express alarm at the “virtual” crimewave. In between studying for final exams, hanging out with friends and refereeing his younger brother’s football matches, the quiet, gentle teenager also gives lessons on e-security(电子安全) to large companies. He reads a lot and exchanges information with other computer experts to know much about the latest tricks of the hacker (黑客) trade.

Many companies have already tried to employ him, but he is not interested at the moment. Instead, he plans to begin law school in the autumn at Sweden’s Uppsala University and start up his own e-security company.

Although he works with the FBI now, his family insists he’s just “a regular kid”. “Jonathan is a great kid, he has his friends and he does a lot more than just play with the computer,” his little sister Tessa said, adding that he helps the FBI because “he likes to help”, not because he’s looking for fame and recognition.

When the world was hit by the “Love Bug” virus, Jonathan was too busy preparing a speech on e-security to look into the problem. “Finally on May 7, I had some free time, so I began looking.” Within a few hours, he had found the suspect and e-mailed his method and results to the FBI. He said his work on the “Melissa” virus, which took three weeks to solve, was a big help in finding the suspect so quickly.

“This time I knew exactly where to start, I knew what to disregard and what to look at.”
