“我不知道”的7种英语口语表达

These are used for saying that you don’t know something because it is impossible for anyone to know it.
当你不知道问题的答案，而且其他人也不可能知道的时候，就可以用这两句。

e.g. ‘Will they ever find the missing aircraft?’ ‘Who knows? The search been going on for such a long time now.’
例句：“他们会找到失踪的飞机吗？” “谁知道呢？搜寻工作已经进行了这么长时间了。”

e.g. ‘How the situation will develop from here is anyone’s guess.’
例句：“谁都不知道事态会如何发展。”

5. Your guess is as good as mine

This is used for saying that you know as little about something as the person who asked you about it.
如果你和提问题的人一样不知道问题的答案，你就可以这样说。

e.g. ‘Do you think we will be able to book the restaurant for Friday?’ ‘Your guess is as good as mine.’
例句：“你觉得我们能在周五预定到这家餐厅吗？”“我和你一样不知道。”

6. Not as far as I know

We use this to say that something may be true, but you do not have enough information to know whether it is or not.
当你认为某件事可能是真的但又不确定的情况下，可以用这个表达。

e.g. ‘Has Clive left the company? I haven’t seen him for ages.’ ‘Not as far as I know, but I haven’t seen him recently either.’
例句：“Clive离开公司了吗？我好久都没见到他了。” “可能吧，我也很久没见他了。”

7. It beats me

This is a rather informal expression to say that you do not know or understand something. “It” is often left out.
这是一种表达你不知道或不懂的非正式用语。“it”可省去。

e.g. ‘Why did he do such a stupid thing?’ ‘It beats me’
例句：“他怎么会做这种蠢事？” “不知道啊”
