You are a German living in Berlin. One day you’ re walk??ing down the street, minding your own business, when sudden??ly a stranger comes up with a smile on his face. After stopping you, he holds a small electronic device (装置) close to his face and speaks slowly into it, saying, in English," Can you tell me where I can buy some sauerkraut?" What should you do? (a) Run away; (b) Call the police; or (c) Listen closely for the device to say in German," Konnen Sie mir bitte sagen, welches sauerkraut haufen kann?"

The most proper answer would be (c) because the person in front of you is only a tourist trying to enjoy himself. The de??vice is said to be the world’s first portable(便携的) translator — a hand-held microcomputer that at the same time translates one spoken language into another. The four-pound, battery-op??erated product is called the Voice, and it is the invention of Advanced Products and Technologies, an American electronics company. When the Voice is introduced in the Unite States in late April — at a price of (1,500 — it will be used to trans??late spoken English into Italian, German, French and Span??ish. The product comes with separate cartridges(盒式存储器) for each of the four languages, which can be changed when the user travels from one country to another. It will be sold in Eu??rope soon after the US introduction, with cartridges that trans??late Italian, German, French and Spanish into English.

The Voice uses a microchip(微型集成电路片) to trans??late languages. It is Started by voice command and produces voice output through a built-in speaker. When the user makes a statement or asks a question, the Voice immediately repeats what has been said in another language.

  For years scientists have been worried about the effects of air pollution on the earth’s natural conditions. Some believe the air inside many houses may be more dangerous than the air outside. It may be one hundred times worse.

  Indoor air pollution can cause a person to feel tired, to suffer eye-pain, headache and other problems. Some pollutants( 污染 物) can cause breathing disorders, diseases of blood and even cancer, Most scientists agree that every modern house has some kind of indoor pollution. People began to notice the problem in the early 1970s. It is that when builders began making houses and offices they did not waste energy. To do this they built buildings that limited the flow of air between inside and outside. They also began using manmade building materials. These materials are now known to let out harmful gases. As the problem became more serious, scientists began searching for a way to deal with it. They discovered a natural pollution control system for building— green plants. Scientists do not really know how plants control air pollution. They believe that a plant’s leaves absorb or take in the pollutants. In exchange the plant lets out oxygen through its leaves and through its tiny organizations on its roots. Scientists suggest that all buildings should have one large plant or several small plants inside for every nine square metres of space. Studies of different plants show that each absorbs different chemicals. So the most effective way to clean the air is to use different kinds of plants. Having green plants inside your house can make it a prettier and more healthy place.

  Generally speaking, indoor air pollution may be more harmful than the air outside because ________.

  A. the man - made building materials let out dangerous gases inside houses

  B. there may be more harmful gases outside houses

  C. the flow of air indoors is limited

  D. indoor air pollution can make a person seriously ill
