语篇理解Many countries are working to improve railroad passenger service along heavily traveled routes that run between cities. Because they use less energy perpassenger than any other means of transportation, modern railroads could help save the world’s energy resources(资源)and reduce air pollution.
The MLV is a new type of high-speed vehicle, which carries people from one city to another. An MLV track is made up of a single rail that lies under the centre of the train, but the train doesn't touch the track when it is moving. MLV’s are powered by electric motors. A powerful magnetic(磁的)force, produced by magnets in both the motor and the track itself. Levitates(悬浮)the train. This magnetic force holds the train about 15 cm above the rail and moves it forward. The train, which was designed by French, German, and Japanese engineers, is expected to travel more than 480 km per hour.
1.An MLV is a sort of ______.
[ ]
A.strong magnitic force
B.special energy resource
C.modern passenger train
D.straight railroad
2.When an MLV is running, there is powerful magnetic force in ______.
[ ]
A.the motor only
B.the track only
C.not only the motor but also the track
D.neither the motor nor the track
3.From the sentence”This magnetic force holds the train about 15 cm above the rail and moves it forward.” We know that when moving forward, an MLV ______.
[ ]
A.is lifted above the track
B.touches the rail all the time
C.leaves the track from time to time
D.floats high above the rail
4.Which of the following is NOT TRUE?
[ ]
A.An MLV runs much faster than an ordinary train.
B.Engineers designed the MLV in order to improve railroad goods service.
C.Modern passenger service could help save energy resources.
D.An MLV doesn’t produce waste gases.
5.The reason to improve railroad passenger service doesn't lie in that ______.
[ ]
A.energy resources ought to be saved
B.people want to reduce air pollution
C.transportation problems remain unsettled
D.more and more passengers don't want to travel by train
