今天要和大家分享的口语表达是：blow it。这个口语表达的意思是：lose an opportunity by doing or saying the wrong thing，就是犯了错，把事情搞砸了，而错过了一个好机会。
因为说话的时候已经做了错事，所以一般用过去时或现在完成时。
- I guess I blew it when I told my teacher I didn't care what grade she gave me.
我想我搞砸了，我不该和老师说我不在乎她给我什么成绩等级。 - I finally got a date with that girl, but I blew it. I overslept, and showed up half an hour late.
我终于约到了那个女孩，可是我搞砸了，我睡过头了，迟到了半个小时。
下面我们再看几个有关例句：
- That was a great opportunity, but now I've blown it.
那是个大好机会，可是我搞砸了。 - She was hoping for promotion but she blew it when she got pregnant.
她希望能够升职，可是她怀孕了，没能如愿。 - He's so stupid, and he's going to blow it!
他太笨了，他会把事情搞砸的。
如果要表达，不要把事情搞砸，你知道怎么说吗？对了，就是，Don't blow it!
