简简单单的字母也可以有大大的用处!可能“言简意赅”说的就是它们了。在日常生活中有一些带有字母的表达，即简单又传神，最主要的是，还容易记住哇，保证你见过一次就会用了!看看下面简单的表达，哪些是你可以用到的吧!

　　A-list = [usually before noun] used to describe the group of people who are considered to be the most famous, successful or important.

　　B-list = [usually before noun] used to describe the group of people who are considered to be fairly famous, successful or important, but not as much as the A-list people.

　　Plan A = the thing or things somebody intends to do if everything happens as they expect.

　　情况一切顺利时原有的计划，例如：

　　Shall we go for plan A or plan B?

　　同理，Plan B就是the thing or things somebody intends to do if their first plan is not successful. 有种backup plan的感觉，例如：

　　If Plan A fails, go to Plan B.

　　from A to B = from one place to another

　　从A地到B地，虚指地点，例如：

　　For me a car is just a means of getting from A to B.

　　with a capital A, B, etc. = used to emphasize that a word has a stronger meaning than usual in a particular situation, or to mean that a particular idea or concept is being understood in only the strictest sense.
