One of the benefits of front load washers is they allow you to fit more laundry into the compartment - which is great for efficiency.

滚筒洗衣机的好处之一，是允许你在内筒里放更多衣服，这极大提高了效率。

And so really in nonfiction, generally what the authors are doing is that they are front loading all of the really good stuff in the introduction in the first three chapters.

所以在非小说类书籍中，一般来说，作者所做的是他们在前三章的导入阶段中把所有的好内容都放进去。
