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 forthhundreds 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.

Several days ago, a Beijing-based IT com­pany fired about 400 people overnight. No one had expected the job cuts, which broke with traditional ways of letting go of workers in Chi­na. Moreover, what was special about this case was that the day before the 400 were fired, they all received from their boss a gift—the book “Who Moved My Cheese?

The book—a bestseller in the US—is being used by men and women to deal with

changes in their lives and work. Some large organizations, including Coca-Cola, Kodak and General Mo­tors, ask their employees to read it in order to encourage them to be active towards changes.

Cheese is something related to everyone’s livelihood—our jobs, the Industries we

work in, relationships and love as well.  

With China’s official entry into the WTO, the whole nation will face more changes

and cha­llenges. So what should we do once this “cheese” on which we are so dependent is moved?

“Whatever challenges and changes we meet, we should face up to them bravely,” Jiang Hengwei, a civil servant said after reading the book.

Professor Zhang Yang in Renmin University of China agrees. “We should change ourway of thinking. The coming competitive foreign com­panies and products provide us withgreat chances to learn from them and improve our own products to meet international standards and be more competitive.”

“With hard work and wisdom, we will create a much larger and better piece of

cheese.” Zhang smiled confidently.

   Once there was an 11-year-old boy who went fishing with his father in the middle of a New Hampshire lake. On the day before bass(巴斯鱼) season opened, they were fishing early in the evening, catching other fish with worms. Then the boy tied on a small silver lure(鱼饵) and put it into the lake. Suddenly he felt that something very big pulling on the lure. His father watched with admiration as the boy skillfully brought the fish beside the bank. Finally he lifted the tired fish from the water. It was the largest one he had ever seen, but it was a bass.

The boy and his father looked at the big fish. The father lit a match and looked at his watch. It was 10 p.m.—two hours before the season opened. He looked at the fish, then at the boy. “You’ll have to put it back, son,” he said.

“Dad!” cried the boy. “There will be other fish,” said his father. “Not as big as this one,” cried the boy. He looked around the lake. No other fishermen or boats were in sight in the moonlight. He looked again at his father.

Even though no one had seen them, nor could anyone ever know what time he had caught the fish, the boy could tell from his father’s voice that the decision couldn’t be changed. He threw the huge bass into the black water. The big fish disappeared. The boy thought that he would never again see such a big fish.

That was 34 years ago. Today the boy is a successful architect in New York City. He often takes his own son and daughters to fish at the same place.

And he was right. He has never again caught such a large fish as the one he got that night long ago. But he does see that same fish ... again and again ... every time he has an ethical (道德的) decision to make. For, as his father had taught him, ethics are simple matters of right and wrong. It is only the practice of ethics that is difficult.
