動腦這件事：腦袋正在轉
這一支就是核心畫面本身：把「想」這個動作整包拿出來當一樣東西講，所以可以 do some thinking，也可以說 have some hard thinking to do。
noun · B1
The activity of using your mind to consider something, work out a problem, or decide what to do.
思考；動腦
核心畫面
You can picture thinking as a mind at work. Something is set in front of it — a problem, a choice, a question — and the mind turns that thing over. Two things come out of the work. One is the work itself: what you are doing when you sit down and go over a problem. The other is what the work leaves behind: the set of ideas and opinions you now hold about it. English uses the same word for both, which is why thinking can mean an hour at the kitchen table and also mean a government's position on aid. One more step out, and the word describes a person: someone who does that work often is a thinking person.

「thinking」可以想成「腦袋正在轉」的畫面。眼前擺著一件事——一個問題、一個選擇、一個疑問——腦袋把它翻來覆去。這個轉動會生出兩樣東西。一樣是轉動本身，也就是你坐下來好好想的那段過程。另一樣是轉完之後留下來的東西，也就是你現在抱著的那套看法。英文用同一個字裝這兩樣，所以 thinking 既能指廚房桌前想了一小時，也能指一個政府對援助的立場。再往外走一步，這個字就拿來形容人：常常這樣轉腦袋的人，就叫 a thinking person。From the word’s history
Wiktionary records thinking as Middle English thinking, formed from think plus -ing. The -ing ending packs an action up into something you can name, which is why one form covers both the act of thinking and what that act leaves behind.
Wiktionary 記 thinking 來自中古英語 thinking，就是 think 加上 -ing。-ing 把一個動作包成一樣可以指稱的東西，這正好說明為什麼同一個字既能指「動腦的過程」，也能指「想出來的那套看法」。

轉完留下的東西：一個人或一群人的看法
從核心畫面往後看一步：腦袋轉完之後留下什麼？留下的就是一整套想法和態度，英文直接拿同一個字來裝它。
noun · B1
The ideas and opinions someone holds about a subject, together with the attitude behind them. It is often used for the view that a group, a government, or a whole field holds at one particular time.
想法；看法
會轉腦袋的人：形容詞用法
把核心畫面貼到人身上：本來 -ing 是「正在轉」，放到名詞前面之後，就變成在說這個人「一向都在轉」。
adjective · B2
Describing a person, or a group such as readers or an audience, who is intelligent and takes the trouble to think carefully about serious or important subjects.
會思考的；有頭腦的
