In only twenty years Asian Americans have become the fastest- growing US minority. As their children began moving up through the nation’s schools, it became clear that a new class of academic achievers was appearing. Their achievements are reflected in the nation’s best universities, where mathematics, science and engineering departments have taken on a decidedly Asian character. This special liking for mathematics And science is partly explained by the fact that Asian-American students who began their educations abroad arrived in the US with a solid grounding in mathematics but little or no knowledge of English. They are also influenced by the promise of a good job after college. Asians feel they will be judged more objectively. And the return on the investment in education is more immediate in something like engineering than with an arts degree.

In recent years, railroads have been combining with each other, merging into super systems, causing heightened concerns about monopoly. As recently as 1995, the top four railroads accounted for under 70 percent of the total ton-miles moved by rails. Next year, after a series of mergers are completed, just four railroads will control well over 90 percent of all the freight moved by major rail carriers.
Supporters of the new super systems argued that these mergers will allow for substantial cost reductions and better coordinated service. Any threat of monopoly, they argue, is removed by fierce competition from trucks. But many shippers complain that for heavy bulk commodities travelling long distances, such as coal, chemicals, and grain, trucking is too costly and the railroads therefore have them by the throat.

A. who work as coordinators
B. who function as judges
C. who supervise transactions
D. who determine the price
For years and years people have been saying that the railways are dead. "We can do without railways," people say, as if motorcars and planes have made the railways unnecessary. We all keep heating that trains are slow, that they lose money, and that they are dying. But this is far from the troth. In those days of expensive oil, the railways have become highly competitive with motorcars and planes. If you want to carry people or goods from place to place, they are cheaper than planes. And they have much in common with planes. A plane goes in a straight line and so does a railway. ,What is more, it takes from the heart of a city into the heart of another. It doesn’t leave you as a plane does, miles and miles from the city center. It doesn’t hold you up as a car . does, in endless traffic jams. And a single train can carry goods which a plane or motorcar could never do.
Far from being dead, the railways are very much alive. Modem railway lines give you
A. it is cheaper to travel by plane than by train
B. the railway station is usually in the suburb of the city
C. when you get off the plane you will find yourself in the center of the city
D. no motorcar or plane can carry as many good as a train does
