当我们表示英语的被动概念时，多用英语的被动语态。除了英语的被动语态外，我们也可以用一些副词来表示，它们会使我们的英语表达不再单一、更丰富。下面分述六个常见的副词。

1.被动结构it’s said that是我们常用的表示“据说”的句型。其实，我们可以用副词supposedly、reportedly来表达当要表示“据说”、“据传；据报道，据传说，据传闻”。比如：

2.admittedly表示“不可否认地，应当承认”。比如：Admittedly, there's a fright factor with nuclear power.必须承认，核能源有一个恐惧因素。This is, admittedly, an ambitious goal.无法否认地是，这是一个野心勃勃的目标。

3.副词undeniably表示“不可否认地，不可否认地，确凿无疑地，不可辩驳地”。比如：Bringing up a baby is undeniably hard work.抚养一个孩子无可否认地是项艰苦的工作。It is undeniably my own handwriting.不可否认，这是我自己的笔迹。Undeniably, the news is grim.不可否认，这些新闻是令人不快的。

4.undoubtedly的意思是“毋庸置疑地，不容置疑地”。比如：There is undoubtedly a great deal of truth in what he says.毫无疑问，他所说的大部分都是实情。

Undoubtedly parents want to raise happy children who are confident, capable and likable rather than spoiled and miserable.毫无疑问，父母想培养的是自信、能干、可爱快乐孩子，而不是被宠坏、痛苦的孩子。

5.understandably表示“可理解地，可以理解，可被料解地”，它可以用来修饰整个句子。比如；You may be understandably suspicious.你或许会持怀疑态度，这是可以理解的。They were understandably disappointed with the result.他们对结果感到失望是可以理解的。
