L38-1: The first calendar
Future historians will be in a unique position when they come to record the history of our own times. They will hardly know which facts to select from the great mass of evidence that steadily accumulates. What is more, they will not have to rely solely on the written word. Films, videos, CDs and CD-ROMS are just some of the bewildering amount of information they will have. They will be able, as it were, to see and hear us in action. But the historian attempting to reconstruct the distant past is always faced with a difficult task. He has to deduce what he can from the few scanty clues available. Even seemingly insignificant remains can shed interesting light on the history of early man.
Up to now, historians have assumed that calendars came into being with the advent of agriculture, for then man was faced with a real need to understand something about the seasons. Recent scientific evidence seems to indicate that this assumption is incorrect.

练习感悟：
有些句子在读的时候，原文里并不会连读，这样听起来还是更能听明白，但是连着就会难以听得出来，读英语应该以能让人听明白为主。
一句话，就是干。
