Blue-sky thinking means sitting with a new idea and not asking yet whether it will work, whether it is cheap, or whether anyone will let you try it. You are only asking what might be interesting. The picture is a clear blue sky: nothing in the way, no walls around the thought.

Blue-sky thinking means的意思是 sitting with a new idea跟一個新想法坐在一起， not asking yet先不問 whether it will work它行不行得通、 whether it is cheap便不便宜、 or whether anyone will let you try it或者有沒有人會讓你試。 You are only asking你只問 what might be interesting什麼可能會有意思。 The picture畫面 is a clear blue sky是一片晴朗的藍天： nothing in the way沒有東西擋路， around the thought想法四周 no walls沒有牆。

It is office and workshop English — meetings, design, school brainstorming. You will hear a blue-sky idea, blue-sky research (curious work, not aimed at a product yet), and, as a mild complaint, "that's a bit too blue-sky," meaning full of ideas but not practical.

It它 is office and workshop English是辦公室和工作坊裡的英文—— meetings會議、 design設計、 school brainstorming學校的腦力激盪。 You will hear你會聽到 a blue-sky idea、 blue-sky research（ curious work出於好奇的研究， not aimed at a product yet還沒有要做成產品）， and和 as a mild complaint當作輕輕抱怨的 "that's a bit too blue-sky,"， meaning意思是 full of ideas想法很多 but但 not practical不實際。

Though actually, people often say it with a half-smile: they want the wild ideas, and then they want someone to bring them back to earth. It is not weather talk, and it is not the same as "out of the blue," which means "suddenly, with no warning."

Though actually不過其實， people often say it人們說它的時候常常 with a half-smile帶著一點笑意： they他們 want要 the wild ideas那些狂想， and then然後 want someone又要有人 to bring them back to earth把它們拉回地面。 It它 is not weather talk不是在聊天氣， and也 not the same as和下面這個不一樣 "out of the blue,"， which means那個的意思是 "suddenly, with no warning."「突然、毫無預警」。
