Okay, now for some practicalities. What do geographers actually do? Well, we collect data to begin with. You'll be doing a lot of that on your first field trip. How do we do this? There are several means. We might, for example, conduct a census, count a population in a given area perhaps. We also need images of the earth's surface which we can produce by means of computer-generation technology or with the help of satellite relays. We've come a very long way from the early exploration of the world by sailing ships when geographers only had pens and paper at their disposal. After we've gathered our information, we must analyse it. We need to look for patterns, most commonly those of causes and consequences. This kind of information helps us to predict and resolve problems that could affect the world we live in. But we don't keep all this information confidential. We then need to publish our findings so that other people can access it and be informed by it. And one way in which this information can be published is in the form of maps.
好吧，现在我们来说点儿有用的--地理学家是做什么的？首先，地理学家收集数据。在第一次实地考察中，你会做大量的数据收集工作。那么，我们又是如何做到的呢？这有一些方法，如，我们可以做调查，可能是在已知的一个区域做人口数量的统计。我们同样需要地表图片，这些我们可以通过计算机时代的科技或是卫星传送得到。我们已经对世界有一段历经久远的探测史，在早期，地理学家只有笔纸然后进行航行探测。 在我们收集好信息之后我们还得进行分析。我们要找到模式规律，一般是其因果规律。这类信息帮我们预测和解决可能影响我们生活之处的问题。 但是我们不会将这些信息保密，而是将我们的发现成果出版，让其他人可以通过这些信息有所习得。此外，这种信息的出版方式之一就是做成地图了。 ——译文来自: 猪猪sunny
