话说昨天我接到了我妹妹的电话，她跟男朋友吵架了，特别伤心。她把他们吵架的内容一句一句转述给我，足足讲了两个多小时！这让我想到了一个习惯用语：blow by blow。
blow这个词本身的意思是“敲击”，而blow by blow作为一个习惯用语的意思是 “详细地描述事情经过”。
- My sister told me the fight blow by blow.
我妹妹把她跟男朋友吵架的事原原本本告诉了我。
下面这个句子谈到一对好莱坞夫妇——Debbie and Charles：
- What's happened to one of Hollywood's hottest couples? First, Debbie learned that Charles had a serious gambling problem. There was a huge fight. A couple months later, Debbie threw all of his belongings into the street. He moved out, and then asked for a divorce. That's the blow by blow so far.
好莱坞最红的夫妇，Debbie和Charles之间到底怎么了? 原来啊，Debbie得知Charles特别好赌，他们俩大吵了一架。几个月之后，Debbie把Charles的所有东西都扔到了大街上。Charles搬了出去，还提出跟Debbie离婚。目前知道的就是这些。
当个明星真不容易。现在社会，各种录音设备齐全，狗仔队很容易就能give a blow-to-blow description of their private life，他们很容易就能详细披露明星的私生活。
我有个朋友前几天在银行外面等人的时候，目睹了一次银行抢劫的经过！他向警方详细描述了他所看到的情况：
- I was waiting outside of the bank. And, through the window, I saw the robber approach the teller, pull out a gun, and demand that she hand over all the money from her drawer. Then he shot at a guard before running out the side door. Since I saw it all happen, it was easy for me to give the police a blow-by-blow description.
我当时在银行外面等人。透过窗户我看到那个抢劫犯走向出纳员，拔出一把枪，逼她把抽屉里的所有现金拿出来。之后他向警卫开枪，从侧门逃了出去。因为我一直在那，所以我能够向警察详细描述事情的全部过程。
有了这么详尽的描述，警察寻找起嫌疑犯来一定容易多了。请大家注意，blow by blow也可以当作形容词来用，意思是“详尽的”。比如说：
- a blow-by-blow description 详尽的描述
- a blow-by-blow analysis 详尽的分析
- a blow-by-blow review 详尽的审查
做形容词的时候，我们一般要在这个短语之间加上hyphen连字符。
