L42-1: Modern cavemen
Cave exploration, or pot-holing, as it has come to be known, is a relatively new sport. Perhaps it is the desire for solitude or the chance of making an unexpected discovery that lures people down to the depths of the earth. It is impossible to give a satisfactory explanation for a pot-holer's motives. For him, caves have the same peculiar fascination which high mountains have for the climber. They arouse instincts which can only be dimly understood.
Exploring really deep caves is not a task for the Sunday afternoon rambler. Such undertakings require the precise planning and foresight of military operations. It can take as long as eight days to rig up rope ladders and to establish supply bases before a descent can be made into a very deep cave. Precautions of this sort are necessary, for it is impossible to foretell the exact nature of the difficulties which will confront the pot-holer.

练习感悟：
今天文章比较难读，生词多，开篇就是长句。第一遍读用了很长时间才顺下来，长句的语气，重音，节奏都很难。听着元音也不容易顺下来。感觉从这篇文章开始，应该就是我能不能读下去的分界线了，感觉文章也比较难懂了，感觉开始要坚持读而不是以前的持续读了，加油！
