今天，我们将跟随优朗英语的Lucy老师，来了解两个词组：“believe it or not”及“before you know it”。相信对于不少学员来说，第一个词组应该不陌生哦~
那么，我们就从“believe it or not”开始吧！
believe it or not 用于告诉别人令人吃惊的事实时，跟对方说信不信由你。
例句：
Charles , believe it or not , actually wrote me a thank-you letter for his Christmas present .
你也许不相信，查尔斯其实给我写了一封感谢信，感谢我送给他圣诞礼物。
Believe it or not , we all share the same birthday , January 1 .
不管你信不信，我们的生日都在1月1号。
情景模拟：

Thanks to components such as transistors and silicon chips ...
We have been able to pack more computing power into a smaller and smaller space .
Now , this little device, believe it or not , is 1000 times more powerful than this huge machine .
现在，不熟悉“believe it or not”的学员，应该也对它有所了解了吧！那么，我们再来看下一个词组“before you know it”。
before you know it 指时间过的比预想的快，不知不觉就过去了，也可写成before he / she / they knew it , 表示事情发生得很快。
例句：
They won't keep you in hospital very long . You'll be back home again before you know it .
他们不会把你留在医院很久的。你将很快就出院回家。
Almost before you know it , he was head of the department and earned $150,000 a year .

情景模拟：

Then , before you know it , you're touching down in a tropical paradise .
以上就是有关“believe it or not”及“before you know it”的介绍了，大家了解了吗？
