参考习作

    Air travelling has two advantages. First it can save a lot of time. For example, it takes two hours and a half to travel from Qingdao to Guangzhou by air while travelling by train takes about 23 hours. second, it is more comfortable and you can rest well on the plane while the train is crowded and you can easily get tired because you must sit a long time. But train travel also has its own advantages. It is much cheaper. Travelling by air costs 1,580 yuan while travelling by train costs only 266 yuan. Besides, you can enjoy the beautiful scenery outside train windows.
    I think different people like different ways of travelling.
