brain的词根词缀（简单词的大用处）

Brain是头脑，前面加上动词rack /ræk/意思就是挖空心思地努力想要记起、理解，或是解决某件事情。

例句：

When I went to pick up my girlfriend, there was a note on the door. She wrote that she didn't want to see me anymore. Huh?! How could our relationship be over? I've been racking my brain trying to recall everything I've done and said lately. Instead of making me struggle, couldn't she at least let me know how I upset her?

我去接我女朋友，发现门上有张条。条上说，她不想跟我交往下去了。我们怎么会就这么结束了呢？我绞尽脑汁，回想最近自己是不是做错了什么事，说错了什么话。她至少可以告诉我我什么地方得罪了她，让我不用这么百思不得其解。

(欢迎在文末下方留言rack one's brain打卡，加强记忆)
