At times we have to announce some event we are going to have. Our announcement, which may be an oral one or a written one, has to be easy to understand.
In general it must contain four W's and one H, which are Who, What, Where, When and How. These are important items to which attention is to be paid. How we arrange these things is entirely up to us.
有时我们不得不宣布一些我们想要做的事情。我们的公告，这可能是一个口头或书面的，都是应该是很容易被理解的。
一般来说它必须包含四个W和一个H，谁，什么事，哪里，何时以及如何做。这些都是重要的项目，必须注意。完全由我们安排这些事情。
