今天洛基小编要分享的英语口语技巧是——7种用英文表达“不确定”的方法。如果你的口语还有待提升，那么存眷洛基小编每天的分享，相信一定可以帮助到你的哦。
1. Perhaps/maybe
These two words are used for saying that you are not certain about something, or that something may or may not be true.
这两个词可以用在你对某事不确定的环境下，或是表达某事可能是真的也可能是假的。
Perhaps is more formal and is used in writing while maybe is used more in spoken English
“perhaps”更加正式，常用在写作中，而“maybe”更多用在口语中。
2. Probably/possibly
These two words can confuse even native speakers. Probably is used for saying that something is likely to be true, and possibly that it may be true but you are not certain.
这两个词很是容易混淆。“Probably”用来表达某件事很可能是真的，“possibly”则表示这件事可能是真的，但你并不确定。
3. Apparently
It is used when what you are saying is based on what you have heard, not on what you know is true and therefore fact.
当你传闻了某件事而不是你本身确定这件事是真的的时候，你可以用“apparently”来表示这件事是事实。
4. As far as I know/ as far as I am aware
These two expressions are used when you have partial (incomplete) knowledge of an issue or fact.
如果你对某个问题了解得不是很全面，就可以用这个词。
5. To the best of my knowledge
This phrase is used for saying that you think something is true, but you are not completely certain. This is quite a formal expression.
当你认为某事是真的，但又不确定的时候可以用这句话。
6. Not to my knowledge
This is used for saying that you think something is not true, although you are not completely certain.
当你认为某事不是真的，但又不确定的时候可以用这句话。
7. I imagine/suppose/guess
These are used when you think something is probably true, but you can’t be sure. “Guess” is more frequently used in American English, although you can hear it in British English, too. “Suppose” is more characteristic of British English and is often used in the negative.
这些词可以用在当你认为某事可能是真的，但又不确定的时候。“guess”更多地呈现在美式英语中，尽管也有英国人会用。但是“suppose”是更加地道的英式英语，并且经常用在否定句中。
