1. comply with与abide by都有遵守的含义，但是二者在用法上有很大的差别: comply with的主语通常为物，abide by的主语通常为人。

2. 这里再补充一点，follow\observe的主语通常也是人；

  另外，conform to的含义一般有两层，一是遵守\符合，二是某种行为与......一致，关于conform to，我这里列出两个例句：

(1) The building does not conform to safety regulations.

  这座建筑物不符合安全条例.

(2) Many of us conform to the outdated customs laid down by our forebears.

　 我们许多人都遵循祖先立下的过时习俗.
