According to the US government, wind farms off the Pacific coast could produce 900 gig watts of electricity every year. Unfortunately, the water there is far too deep for even the tallest windmills(see picture)to touch bottom. An experiment under way off the coast of Norway, however, could help put them anywhere.

The project, called Hywind, is the world’s first large-scale deepwater wind turbine(涡轮发电机).Although it uses a fairly standard 152-ton,2.3-megawatt turbine, Hywind represents totally new technology. The turbine will be fixed 213 feet above the water on a floating spar(see picture),a technology Hywind’s creator, the Norwegian company StatoilHydro, has developed recently. The steel spar, which is filled with stones and goes 328 feet below the sea surface, will be tied to the ocean floor by three cable(缆索)；these will keep the spar stable and prevent the turbine from moving up and down in the waves. Hywind’s stability(稳定性)in the cold and rough sea would prove that even the deepest corners of the ocean are suitable for wind power. If all goes according to plan, the turbine will start producing electricity six miles off the coast of southwestern Norway as early as September.

To produce electricity on a large scale, a commercial wind farm will have to use bigger turbines than Hywind does, but it’s difficult enough to balance such a large turbine so high on a floating spar in the middle of the ocean. To make that turbine heavier, the whole spar’s to design a new kind of wind turbine, one whose gearbox(变速箱) sits at sea level rather than behind the blades (see picture )

Hywind is a test run, but the benefits for perfecting floating wind-farm technology could be extremely large. Out at sea, the wind is often stronger and steadier than close to shore, where all existing offshore windmills are planted. Deep-sea farms are invisible from land, which helps overcome the windmill-as-eyesore objection. If the technology catches on, it will open up vast areas of the planet’s surface to one of the best low-carbon power sources available.

       A CAR design team is bringing back memories of a famous scene from a James Bond movie by producing a car that can travel under water．

       In the 007 film, The Spy Who Loved- Me （1977）, Bond drives below the waves in a vehicle that moments earlier seemed to be an ordinary car．

       The scene was shot using special movie magic, but more than 30 years later the Swiss company Rinspeed has come up with a concept （概念） car - the sOuba．It is an open-topped sports car that car drive over land, above the waves and even under water to a depth of 10 meters．It is to be displayed at next month's Geneva Motor Show．

       Rinspeed boss Frank Rinderknecht, 52, is a James Bond fan．"For three decades I have tried to imagine how it might be possible to build a car that can fly under water," he said．"Now we have made this dream come true．”

       To make sQuba, Rinspeed took a sports car and replaced the ordinary engine with several electric motors．Three motors arc located in the back of the car．One provides power on land while the other two drive the screws （螺旋桨） underwater．

       For safety reasons sQuba was built as an open car so that people can get out quickly in an emergency．With an enclosed cabin （封闭车厢） opening the door might be impossible because of water pressure．

       sQuba is easy to drive．When you go into the water it floats, until you open the door to let the water in．Soon the sQuba starts on its way to the underwater world．To breathe, you'll have to wear a scuba mask（潜水面罩） connected to the car's compressed-air （压缩空气） tank．The vehicle can stay under water until you run out of air, which is about two hours．

       Sadly, those people excited by the sQuba may never be able to drive one as there are no plans to put it into production．

       "It's a tradition that we produce a concept car for the Geneva Motor Show．"said Rinderknecht．"We don't plan to build it," he admitted．

1．The sQuba can drive both on land and under water because ____．

     A．it was designed with an enclosed cabin

     B．it was built as an open-topped sports car

     C．three screws are positioned in the back of the car

     D．electric motors are equipped instead of an ordinary engine

2．The sQuba was produced to____．

     A．help shoot a scene in a 007 film

     B．update some water sports cars

     C．be tested before going into production

      D．be put in a motor exhibition

3．It can be inferred from the passage that ____．

     A．the sQuba probably can't run at the bottom of deep sea

     B．the sQuba will probably sell well in the market of Geneva

     C．the shape of sQuba is totally different from an ordinary car

     D．the driver in the sQuba can't breathe freely when floating on water

4．The writer of the passage would agree that ____．

     A．Rinspeed will make a lot of money by selling the sQuba

     B．Rinderknecht plays a role in the invention of the sQuba

     C．007 film directors will be interested in using the sQuba

     D．it's a waste of money to design an concept car for a motor show
