5、避免陈词滥调等废话

例如：For getting a satisfying score, students have to prepare for and review their texts frequently, remember all the knowledge they have learned deep in mind, enlarge their learning if it is possible and so on, especially when examinations are coming. All these efforts, no matter what their aims are, will surely lead to a corresponding paying back.

　　段中的这一句"no matter what their aims are"，在整个上下文表达上面没有任何实质性的意　义，完完全全是句废话。
