Question

The traditional dream of Chinese philosophers to be able to “run with the wind” became a reality this New Year's Eve day.

    The Shanghai Transrapid Maglev Line(首次)test run and the first commercial maglev(magnetic levitation)system in the world was put to use.

    The project is a joint effort by China and Germany. It cost 10 billion Yuan and took two and half years to complete.

    The maglev train ran smoothly，building up speed to 427 kilometers per hour. It covered a 45-minute journey by car in all easy eight minutes. However，the short trip costs as much as 50 Yuan. There are speculations(推测)that within ten years there could be a line from Shanghai to Beijing－1,280 kilometers. The journey would only take three hours. The total cost of the maglev would be about US$24 billion.

    Unlike the current railway system with traditional tracks，the maglev runs on magnetic levitation linen. The powerful electric current enables the fast train to rise above the line and float.

    A maglev system can reach speeds of up to 400～500 kilometers per hour，much faster than any normal railway system. The lack of contact between the train and the maglev “tracks” reduces the noise level and the damaging effect on the land of a city.

   The maglev system is also energy-efficient. Its energy consumption(消耗)is only about half that of cars and a quarter that of aircraft with the same transport capacity.

   The effect of the magnetic force of the maglev system on passengers and nearby  areas is minimal since the effect on humans is less than that of most electric household  appliance(家用电器).

  A. no other countries in the world except China have studied the Shanghai Transrapid Maglev lane

  B. the cost of taking a journey in the maglev train is too high

  C. the Shanghai Transrapid Maglev Line will attract more visitors to Shanghai

  D. Germany is the only partner for China in Shanghai

 4. The author thinks　　　　    .

  A. one of China's long—term dreams has come true

  B. Shanghai takes the lead in high-tech in China

  C. the cost of the maglev train is beyond the ability of Shanghai

  D. maglev trains will take the place of many transportation tools
