翻译：把人群看作服从相当简单规则(与物理规则无异)的 “ 社会原子 ”，我们就会发现某些规律。比如，拥挤的人群中产生队伍的方式。在最初混乱无序的运动中，一个人开始跟随别人 —— 为了避免碰撞 —— 人流出现了。随着越来越多的人加入队伍，其他人也越来越倾向于进入人流，继而某些特定的队伍形成了自我秩序。

inflexible 不易弯折的，不屈的，坚定的，不可改变的
straightforward 坦诚直白的，直接的，直线的，易懂的，易做的

三空题并不意味着难度更高，其实从官方给出的统计看，难度和空格数没有明显关联。
这不禁让我们意识到一个令人难堪的事实，如果你觉得空越多越难，有可能只是因为你不认识单词，随着文本长度的增加，越来越多的不认识的单词最终变成无法排除的扰动因素，你的正确率也相应地变得越发可怜。
