问题     Why do we study geography and what is its value to us? Geography is intrinsically interesting and may be studied and enjoyed on this account alone, but it has many practical and utilitarian values. Firstly, it helps us to understand and appreciate the forms and features of the landscapes and the human imprint on the physical environment. Through this understanding man can learn how best to make use of the land and its resources for his own benefits. In the past he has brought calamity and misery upon himself simply because he has failed to understand the environment in which he lives. A knowledge of geography will help him to avoid making tragic mistakes similar to those of the past.
    Secondly, we are living in a world of increasingly rapid transport and new means of communication; distances are becoming less in the sense that the traveling time is being constantly reduced. Jules Verne’s hero, using every device possible, managed, a hundred years ago, to get round the world in eighty days; today we can get round it in as many hours. As a result of speed in transport and communication, the world is getting smaller and the peoples living in different parts of the earth are becoming more closely linked together. It is important, therefore, that we should know as much as possible about the places and peoples in other parts of the world.
    Thirdly, we must remember that anything that happens any where in the world, such as a war in South-east Asia, a revolution in South America, a flood in India, or an economic recession in the United States, may have, and often does have, repercussion throughout the world. In other words, few, if any, countries can live, these days in complete isolation and shut their eyes to what is going on in the world around them.
    Fourthly, geography is of even more direct importance, for many countries, of which Britain is a typical example, live by what they can make in factories and export. They cannot produce their manufactured goods without the raw materials they import; and these, as well as much of their food, have to be paid for by exports. It is important, then, to know how other people live, what their wants are, what raw materials they have for sale, what languages they speak, and how mutual exchange can best be undertaken. Thus, from a purely selfish point of view, we should study geography.
Today we can get round the world in ______ hours.
