Infer is sometimes confused withimply, but the distinction is a useful one.When we say that a speaker or sentence implies something,we mean that it is conveyed or suggested without being stated outright:
Infer 有时会和imply 混淆在一起， 但它们之间的差异是很重要的。当我们说某个说话人或某个句子暗含有某种东西时，我们的意思是这种东西是含在其中的或暗示的而没有公开说出来：
例句：
When the mayor said that she would not rule out a business tax increase, she implied (not inferred ) that some taxes might be raised.
当市长说她不排除商业税增涨的可能性时，她暗指（不是 inferred ) 可能要提高某些税收。

Inference, on the other hand, is the activity performed by a reader or interpreter in deriving conclusions that are not explicit in what is said:
而推论则是读者或阐释者的一种活动，他们推断出的结论是言语中没有明确表达出来的：
例句：
When the mayor said that she would not rule out a tax increase,
当市长说她不排除商业税增涨的可能性时，

we inferred that she had been consulting with some new financial advisers,since her old advisers were in favor of tax reductions.
我们推断她同几个新的金融顾问们商量过，因为她的那些顾问们支持减税。
