【正确答案】[参考范文] High-Speed Rail Accompanying with the rapid development of science and technology,more and more convenient transport networks have been formed．Consequently,there are more alternatives for our trips．However,the construction of High-speed rail(HSR)is still gathering momentum in China．As far as I am concerned，HSR is a optimal choice． Fore one thing，the HSR is a dream for speed and comfort at the same time，which is faster and more comfortable than the ordinary ones．Unlike other modes of travel，high speed rail passengers are free to walk on the train between different areas，such as the dining area，lounge and business center．More importantly,adoption of HRS for travel is much safer than that by air,it can run with minimal environment impact． For another thing，High-speed trains travel from one city center to another city center．For most passengers，the rest of the trip is a simple walk or short taxi ride from the train station to their destination．On board the High—speed passenger trains，there is much space for business travellers to work and reach the business centers，complete with office amenities． Beyond all doubt，to keep the train in good condition requires a great deal of money．Thus the ticket fare is quite expensive，which hangs the low—income groups back． Weighting the advantage and disadvantage，we can find that the HSR is the best way for US． We complain about its higher price，and we believe its price is as high as that of a plane，which is strict with the weather．Therefore，it iS very necessary for US to build this network now and it will be the developing trend in future．
