Only here and there along each strand do you find sections that control and organize vital functions.

每一段里你发现只有部分区段在起着掌控和组织作用。

And the easiest way to do that is by taking a map and placing many equally sized segments or rulers around the country's perimeter and then adding up the length of those segments.

最简单方法就是拿一张地图，在这个长围划大小相等区段或标尺，然后把这些区段长度加起来。

And, a little less obvious tip to attach to that, actually look on the university website and map, figure out what the locations and room numbers of your classes are, and put that in the details section of Google Calendar.

还有一个虽然不太容易发现和这个有关技巧，请大实际到大学网站和地图，找出课地点和你课教室编号然后将这些资讯放入 Google 行事历详细资料区段。
