问题     As we have learned in our previous lectures, our country generally has an excellent system of transportation. There are efficient airlines, railway systems as well as motorway all across the country; however, if you have been to an airport recently, you’ ve probably noticed that it is becoming more and more crowded. Although airplanes provide the faster way to travel hundreds or thousands of miles, I don’ t think that our industry can do a good job of transporting people between cities that only a short distance apart. A person who travels between London and Birmingham, the so-called strip cities, may spend only relatively a short time in the air while spending several hours getting to and from the airport. This situation makes flying almost as time consuming as driving and of course more expensive, moreover, planes use a lot of fuel in taking off and landing down. So they are simply not fuel efficient on short flights. In my opinion, high speed train may be an answer to that problem. By the end of last century, a proposal for such a train was put forward, this new type of train is called maglev, meaning magnetic levitated train, the maglev train will not ride on the tracks, but will make use of the magnetic repulsion to glide or float above the tracks. Since the train and tracks do not touch and rub against each other, a lot of maintenance work can be saved. These trains will be able to travel at a speed about 300 miles per hour. Undoubtedly, at this speed, conventional trains will have trouble, staying on the tracks. At present, the operation of maglev trains is still on the experimental stage, for example, Germany and China. However, I’ m sure this new type of train on the horizon will revolutionize transportation of the 21st century, the way airplane did in the 20th century.
Which of the following stratagems is Not True?
选项 A、Airplanes are more efficient means of traveling over long distance.
B、Maglev trains are more reliable than short flight planes.
C、The travel to and from the airport is time-consuming.
D、Strip cities are cities which are short distance apart.
答案B
解析 文中主要讲到在很近的城市之间旅行乘坐飞机既消耗时间又浪费能源，而悬磁浮列车可以解决这一问题。可以说Maglev trains are more efficient than short flight planes。而作者并没有说悬磁浮列车是否更reliable。
