8個簡單的日常短語 但來源你絕對想不到！ - 英語口語
1.Pass the buck----shift the responsibility to someone else 推卸責任
We all know that buck is informal American English for a dollar. Indeed, it can also be used for an Australian dollar, a New Zealand dollar, a South African rand, and an Indian rupee – but none of those senses are related to pass the buck.
我們都知道buck是美元dollor非正式的美式英語表達。實際上，buck也可用于表達澳元，新西蘭元，南非蘭特和印度盧布-但所有這些含義都和pass the buck 這個習語沒有聯系。
This particular buck is ‘an article placed as a reminder in front of a player whose turn it is to deal at poker’ – which means passing it make much more sense. This item also gives us the phrase the buck stops here; both figurative phrases have moved far beyond their poker origins.
這里的buck是特指“在紙牌游戲中當輪到某人發牌時，放置在玩家面前作為提示的物品”，這樣傳遞這個物品便有了更多的含義。這件物品同樣給了我們另一個短語the buck stops here（責無旁貸）；這兩個比喻意味的短語，其含義已經遠遠超出了撲克的起源。
2.Turn over a new leaf----start to act or behave in a better or more responsible way 改過自新
It has nothing to do with foliage,but relates to another common use of leaf: one of the pages in a book. A similar derivation gives us to take a leaf out of someone’s book, meaning ‘imitate or emulate someone in a particular way’.
這個短語和葉子無關，而和leaf另一個常見的含義有關：書中的一頁。類似的引申出to take a leaf out of someone’s book這個短語，表示“模仿某人”。
3. Push the envelope----to approach or extend the limits of what is possible 接近甚至超越限度
This envelope isn’t the sort you’d put letters in.Push the envelope was originally aviation slang relating to graphs of aerodynamic performance and exceeding the set of limiting cobinations of speed and altitude.
這個信封并不是我們裝信的信封。Push the envelope最初是航空俚語，與空氣動力性能的圖表相關并且超過速度和高度的合并限制。
4. Ring the changes----vary the ways of expressing or doing something 以不同的方式做(或說)同一件事
This phrase has nothing to do with pen and paper. Instead, it came originally with allusion to bell-ringing and the different orders in which a peal of bells may be rung.
5. Leave someone in the lurch----leave an associate or friend abruptly and without assistance or support when they are in a difficult situation讓 某人陷入困境
The word lurch in this phrase derives from the French lourche, which is the name of a game resembling backgammon.
6. Lick into shape----act forcefully to bring someone or something into a fitter, more efficient, or better-organized state 塑造；使成型
In Medieval Europe, it was believed that bears’ young were born shapeless, and licking into shape refers to the alleged practice of bears licking their offspring into ursine form.
在中世紀的歐洲，人們認為熊生下來是沒有形狀的，lick the shape指的是熊將他們的后代舔成熊的形狀。
7. Flash in the pan----a thing or person whose sudden but brief success it no repeated or repeatable 曇花一現
If you’re thinking anything to do with cooking or panning for gold, then you’re barking up the wrong tree: flash in the pan is with allusion to the priming of a firearm. The flash arises from an explosion of gunpowder within the pan, which was a part of the lock that held the priming in old types of gun.
如果你想到的是烹飪或者淘金相關，那么你便找錯了目標，flash in the pan與火槍的推進器有關。光亮由火藥盤內的火藥爆炸時產生，火藥盤是槍支保險栓的一部分，在老式槍支中用來完成推進。
8. Pull out all the stops----make a very great effort to achieve something 使出渾身解數；全力以赴
These stops are organ pipes of a particular tone and range of pitch and the handles which control them; by pulling all the stops out, you would create a louder, more elaborate sound.
