老外說no brainer，是說你沒腦子嗎？
如果有人對你說no brainer這樣的話時，你會不會下意識地聯(lián)想到“無腦” 這個詞呢？其實這可就是望文生義了哦~no brainer actually means that something so simple or obvious that you do not need to think much about it，就是“很簡單無需用腦的事；顯而易見不傷腦筋的事”。
在英語里，我們可以用 no-brainer 來形容生活中極其簡單的事情，顯而易見的做法或者不假思索就能想到的。這個說法還可以用來強調(diào)、說明一個決定很容易做出，根本不需要傷腦筋去想。一般以單數(shù)形式出現(xiàn)：a no-brainer
比如說你喜歡的女生約你出去玩兒，It‘s a no brainer you will hang out with her.不用動腦筋想也知道你肯定會爽快地答應(yīng)，對吧。
我們再來一起學習一些例句：
This question is too easy. It’s a no-brainer.
這個問題太簡單了，完全不用花腦筋想。
When George had to choose between either sitting at home all day doing nothing or coming out with me for a bit of fun in the park, it was a no-brainer!
當喬治面對在家無聊得呆一天或跟我到公園去玩這兩個選擇時，我不用想都知道他會選哪個。
This sounds like a no-brainer, especially for those people with language skills.
這個聽起來太簡單了，尤其是對于那些有語言技能的人。
2.Rack your brains 絞盡腦汁
To rack one's brains is to strain mentally to recall or to understand something. 簡單地說呢，就是to think very hard

他們讓我提出一些新想法，但是我絞盡腦汁，卻一個也想不出來。
另外，rack your brains 除描述一個人因為一件事苦苦思索以外，還可以用作祈使句來命令或請求他人仔細思索，想出點子、計劃或方案等。
I need you to help me come up with three alternative plans for the project in two hours. So, rack your brains!
