社会风俗习惯增加了学习外语的难度。

The main purpose of this part is to illustrate the social norms, which about the maintenance of social order and mediation of civil disputes, are not only national laws but also the civil society norms constructed by social customs and social habits.

此部分的写作目的主要是为了说明在农村，维持社会秩序、调解民事纠纷的社会规范不单单是国家法律，而是一种国家法律和由社会风俗、习惯等组成的民间社会规范共同影响的局面。

Understandably they regard culture more as social customs and habits, which, in Wu's eyes, are but the most trivial aspect of culture and often change with time.

而在新文化派眼里，文化是一个民族的生活方式，因此他们更多着眼的是风俗制度层面，而这在吴宓的眼里恰是枝叶，是可以随着时代的变化而变化的。
