许多通许会觉得“同意”。并且，立刻想到的一个理由是“人以群分”。再于是，很快就出现了下面这个句子：

People gather for their similarity, and therefore, knowing one leads to knowing others, and, more importantly, vice versa.

但是，困难也随之而来：这个句子仿佛说明白了一切，接下来讲道理吧，感觉也没什么可以进一步讲的，举例子吧，感觉也是多余。那怎么办？

“倒过来”写。

当道理太简单的时候，“倒过来”（不是习惯性的“总—分”的展开结构，而是“分—总”的归纳结构）写。

道理不急说，先描绘情况（举例子），再总结道理。

比如：

废话一句（怎么说合理的废话，也是写作的重要技巧）： I believe what the statement says for I practice this principle quite often and get good results. 例子出现： When I consider a candidate for the partnership of my business, I find that who the candidate mingles with provide the clue. The individual is less likely to be friends with people who have no business ambitions or desire for financial success than to be friends with people who share or relate to his aspiration. As I learn about the whole group's financial pursuit, I learn about the target person's business goal. 个例子结束，第二个例子出现：This is analogous to how we know whether we have found the right romance. A frugal one, seeking the suitable romantic relationship, may pass over a candidate when he or she sees the candidate's friends all living life in a lavish style, because the candidate is considered most likely to live the same luxurious life, based on the common belief that people gather for their similarity. 例子结束，总结道理，段落收官：In light of the above, knowing one leads to knowing others, and, more importantly, vice versa.
