1. Back to Square One｜回到原點

🇬🇧 ความหมาย: To go back to the beginning because a plan or attempt has failed completely. It means starting over from scratch with nothing to show for your previous efforts.

🇹🇼 中文意思： 指某件事情失敗了，必須從頭開始，一切回到最初的起點，之前的努力付諸東流。

Origin 起源： This idiom is believed to come from early 20th century board games, where landing on certain squares would force a player back to the starting square. Some also trace it to 1930s BBC radio football commentaries, where the pitch was divided into numbered squares on a grid printed in the Radio Times — if play went back to square one, it meant the ball was back at the goalkeeper’s end.

這個慣用語據信源自20世紀初的棋盤遊戲，當棋子落在某些格子時必須回到起點。另一個說法是1930年代BBC廣播足球評論，當時球場被分成編號方格，第一格（square one）在守門員區域，所以回到第一格代表一切重來。

Example Sentences 例句：

• We thought our business plan was perfect, but the bank rejected our loan application. Now we’re back to square one. （我們以為商業計畫很完美，但銀行拒絕了我們的貸款申請，現在一切回到原點。）
• After two years of development, the software crashed on launch day. The whole team had to go back to square one. （經過兩年的開發，軟體在上線當天崩潰了。整個團隊不得不重新來過。）
• “How did the project go?” “Terrible. We’re back to square one.” （「專案進行得怎麼樣？」「糟透了，我們回到原點了。」）

2. In Seventh Heaven｜在第七天堂

🇬🇧 ความหมาย: To feel extremely happy, ecstatic, or in a state of pure bliss. When someone is in seventh heaven, they are experiencing the highest possible level of happiness and joy.

🇹🇼 中文意思： 形容某人感到極度開心、欣喜若狂，處於最高層次的幸福狀態，如同置身天堂一般。

Origin 起源： This expression comes from ancient Semitic cosmology and later Islamic and Jewish religious traditions. In these belief systems, the universe was thought to consist of seven heavens stacked one above the other. The seventh and highest heaven was considered the dwelling place of God himself — the ultimate state of perfection and bliss. In Kabbalistic tradition, the seventh heaven is called Araboth, the highest realm of all.

這個表達源自古代閃米特宇宙論，以及後來的伊斯蘭教和猶太教傳統。在這些信仰體系中，宇宙被認為由七層天堂疊加而成，第七層也是最高層的天堂是神的居所，代表著完美和極致幸福的境界。

Example Sentences 例句：

• When she got accepted into her dream university, she was in seventh heaven for days. （當她被夢寐以求的大學錄取時，她高興了好幾天，彷彿身在天堂。）
• My son is in seventh heaven — he just got the gaming console he’s been wanting for months. （我兒子簡直樂壞了，他剛拿到那台他渴望已久的遊戲機。）
• After weeks of hard work, passing the IELTS exam put me in seventh heaven. （在幾週的努力備考後，通過雅思考試讓我欣喜若狂。）

3. On Cloud Nine｜飄飄欲仙

🇬🇧 ความหมาย: To feel extremely happy, elated, or euphoric. Similar to “in seventh heaven,” being on cloud nine describes a state of intense happiness where everything feels perfect and wonderful.

🇹🇼 中文意思： 描述一種極度快樂、心情飄飄然的狀態，感覺一切都美好無比，好像踩在雲端上一樣輕盈快樂。

Origin 起源： The most widely accepted origin comes from the U.S. Weather Bureau’s classification system for clouds, where Cloud 9 — the cumulonimbus cloud — is the highest and most dramatic type of cloud, reaching up to 40,000 feet. Being “on cloud nine” meant being at the very top, the highest point imaginable. The phrase became popular in American English in the 1950s.

最廣為接受的起源來自美國氣象局的雲層分類系統，第9號雲（積雨雲cumulonimbus）是最高、最壯觀的雲層類型，高度可達40,000英尺。處於「第九號雲」意味著在最高處。這個片語在1950年代的美式英語中廣泛流行。

Example Sentences 例句：

• He’s been on cloud nine ever since he got the job promotion last week. （自從上週晉升之後，他就一直飄飄然的。）
• She was on cloud nine after her first date with the man she’d been admiring for months. （在與她心儀已久的男士第一次約會之後，她心情好極了。）
• Winning the championship put the entire team on cloud nine. （贏得冠軍讓整個球隊都欣喜若狂。）

4. At the Eleventh Hour｜在最後一刻

🇬🇧 ความหมาย: At the last possible moment; just before it’s too late. This idiom is used when something happens or is done right before a deadline, often unexpectedly saving a situation.

🇹🇼 中文意思： 在最後一刻，在截止時間前的最後關頭才完成或發生某事，通常帶有「及時化險為夷」的意味。

Origin 起源： This expression comes from the Bible, specifically the Parable of the Workers in the Vineyard (Matthew 20:1-16), where workers hired at the “eleventh hour” (one hour before the end of the twelve-hour working day) received the same wages as those who worked all day. In modern English, it took on its current meaning of “the last possible moment” in the early 19th century. It became especially associated with the end of World War I — the Armistice was signed at the 11th hour of the 11th day of the 11th month, 1918.

這個表達來自聖經，具體是《馬太福音》20章中葡萄園工人的比喻，在「第十一個小時」（十二小時工作天結束前一小時）受雇的工人獲得了與全天工作者相同的報酬。在現代英語中，它在19世紀初獲得了「最後一刻」的含義，並因第一次世界大戰的停戰協議在1918年11月11日第11小時簽署而廣為人知。

Example Sentences 例句：

• We thought the deal was going to fall through, but at the eleventh hour, both sides reached an agreement. （我們以為交易會告吹，但在最後關頭，雙方達成了協議。）
• She submitted her university application at the eleventh hour — just five minutes before the deadline. （她在最後一刻提交了大學申請，距截止時間只剩五分鐘。）
• The rescue team arrived at the eleventh hour to save the hikers trapped on the mountain. （救援隊在最後一刻趕到，拯救了被困在山上的登山者。）

5. Put Two and Two Together｜推斷出真相

🇬🇧 ความหมาย: To reach an obvious conclusion by putting together two or more pieces of evidence or information. It means to figure something out by logical deduction.

🇹🇼 中文意思： 將兩件或多件事情的線索結合起來，推斷出合理的結論。就像2加2等於4一樣，意思是根據已知信息得出顯而易見的推論。

Origin 起源： This idiom draws on the simple arithmetic fact that 2 + 2 = 4, suggesting that just as basic math has an obvious answer, combining two pieces of information should lead to an obvious conclusion. The phrase has been used in English since at least the late 18th century, and it often implies that the conclusion was easy to reach — sometimes used with the phrase “put two and two together and make five” to describe someone who draws the WRONG conclusion.

這個慣用語源自簡單的算術，2加2等於4，就像基礎數學有明顯答案一樣，將兩條線索結合起來應該能得出明顯的結論。這個片語在英語中至少使用了200年，有時也用「put two and two together and make five」來形容某人得出了錯誤結論。

Example Sentences 例句：

• When I saw her car parked outside his apartment and put two and two together, I realized they were dating. （當我看到她的車停在他公寓外面，把線索串連起來，我意識到他們在約會。）
• The detective quickly put two and two together: the muddy boots, the torn jacket, and the missing dog all pointed to the same suspect. （偵探很快就推斷出來：泥濘的靴子、破損的外套和失蹤的狗都指向同一個嫌疑人。）
• It didn’t take long to put two and two together and figure out why he was being so secretive. （沒過多久我就推斷出他為何如此神秘兮兮了。）

6. A Catch-22｜進退兩難

🇬🇧 ความหมาย: An impossible situation where conflicting rules or conditions trap you in a no-win scenario. No matter what you do, you can’t win — each solution creates a new problem that prevents you from achieving your goal.

🇹🇼 中文意思： 指一種進退兩難、無論怎麼做都無法勝出的困境。兩個相互矛盾的規則或條件讓人陷入兩難困境，每個解決方案都會帶來新的問題。

Origin 起源： This idiom comes directly from Joseph Heller’s 1961 novel “Catch-22.” In the novel, the rule states that a pilot can be grounded for being insane, but asking to be grounded proves the pilot is sane. This circular logic creates an impossible trap. The novel became enormously influential, and “catch-22” entered everyday English to describe any no-win paradoxical situation.

這個慣用語直接來自約瑟夫·海勒1961年的小說《第22條軍規》。小說中的規定是：飛行員可以因精神失常而停飛，但要求停飛本身就證明了飛行員是清醒理智的。這種循環邏輯製造了一個無法解脫的困境。這部小說影響深遠，「catch-22」進入了日常英語，用來描述任何進退兩難的悖論情況。

Example Sentences 例句：

• It’s a real catch-22: I need work experience to get a job, but I need a job to get work experience. （這真是個進退兩難的困境：我需要工作經驗才能找到工作，但我需要找到工作才能獲得工作經驗。）
• The housing market is a catch-22 for young people — they can’t save enough for a deposit because rent is too high. （房市對年輕人來說是個兩難困境——他們無法存夠頭期款，因為租金太高了。）
• We faced a classic catch-22: the charity couldn’t get funding without a track record, but couldn’t build a track record without funding. （我們面臨了典型的兩難困境：慈善機構沒有業績記錄就無法獲得資金，但沒有資金就無法建立業績記錄。）

7. Kill Two Birds with One Stone｜一石二鳥

🇬🇧 ความหมาย: To accomplish two goals with a single action; to solve two problems at the same time with one effort. It’s about maximum efficiency — getting double results from a single action.

🇹🇼 中文意思： 用一個行動同時達成兩個目的，一舉兩得。強調效率最大化，一個行動可以解決兩個問題或完成兩件事情。這與中文的「一石二鳥」或「一箭雙雕」意思完全相同！

Origin 起源： This expression has been part of English since at least the 17th century. Some trace it to the ancient story of the Greek hero Daedalus, but most likely it originated as a literal observation about hunting — skillful hunters could sometimes kill two birds with a single throw of a stone. The idiom appears in written English as early as 1656 in the works of Thomas Hobbes.

這個表達在英語中至少已有17世紀的歷史。有些人將其追溯到古希臘英雄代達羅斯的故事，但更可能的起源是對打獵的字面描述——技術嫻熟的獵人有時能用一塊石頭打中兩隻鳥。這個慣用語早在1656年就出現在湯瑪斯·霍布斯的著作中。

Example Sentences 例句：

• I killed two birds with one stone by going to the gym near my office — I get my workout in during my lunch break. （我找了一家辦公室附近的健身房，一舉兩得——在午休時間就完成了鍛煉。）
• She killed two birds with one stone by studying in a café — she got her homework done and caught up with a friend. （她在咖啡館裡學習，一石二鳥——既完成了作業，又和朋友敘了舊。）
• Taking an online English course during my commute kills two birds with one stone. （在通勤時間上英語在線課程，可謂一舉兩得。）

8. At Sixes and Sevens｜亂七八糟

🇬🇧 ความหมาย: In a state of confusion, chaos, or disorder. When something is at sixes and sevens, it’s completely disorganized, messy, or uncertain.

🇹🇼 中文意思： 形容一種混亂、無秩序的狀態，一切都亂七八糟，讓人摸不著頭緒，不知從何下手。

Origin 起源： This is one of the oldest idioms in the English language, dating back to the 14th century. It originally appeared in Geoffrey Chaucer’s “Troilus and Criseyde” as “to set on six and seven,” meaning to risk all on a chance. The current meaning of disorder came later. Another theory traces it to a dispute between two powerful London trade guilds — the Merchant Taylors and the Skinners — who couldn’t agree on their ranking order (6th and 7th place), causing constant confusion.

這是英語中最古老的慣用語之一，可以追溯到14世紀。它最初出現在喬叟的《特洛伊羅斯與克瑞西達》中，原意是「孤注一擲」。混亂的含義是後來才有的。另一個理論將其追溯到倫敦兩個強大行業公會——商人裁縫公會和皮草商公會——之間關於排名順序（第6和第7位）的爭議，導致持續的混亂局面。

Example Sentences 例句：

• After the office renovation, everything was at sixes and sevens — nobody could find anything. （辦公室裝修後，一切都亂七八糟的，沒有人能找到任何東西。）
• Moving to a new city left her feeling at sixes and sevens for the first few weeks. （搬到新城市的頭幾週，她感到一切都亂糟糟的，不知所措。）
• The new manager’s sudden resignation left the whole department at sixes and sevens. （新經理突然辭職，讓整個部門陷入混亂。）

9. Six Degrees of Separation｜六度分隔理論

🇬🇧 ความหมาย: The concept that any two people in the world are connected to each other through a chain of no more than six social connections. The world is smaller than we think — everyone is connected.

🇹🇼 中文意思： 一個理論：世界上任何兩個人之間，最多只需要通過六個人的社交連結就能相識。這說明世界比我們想像的小得多，每個人都以某種方式與其他人相連。

Origin 起源： Hungarian author Frigyes Karinthy first proposed this concept in 1929 in his short story “Chains.” The theory was later scientifically explored by social psychologist Stanley Milgram in his famous 1967 “small world experiment.” Milgram found that the average number of links between any two people in the United States was about 5.5. The phrase “six degrees of separation” became widely known after John Guare’s 1990 play of the same name, and later the popular game “Six Degrees of Kevin Bacon.”

匈牙利作家弗里傑什·卡林西首先在1929年的短篇小說《鏈條》中提出了這個概念。社會心理學家斯坦利·米爾格拉姆後來在1967年著名的「小世界實驗」中對這一理論進行了科學研究。米爾格拉姆發現，美國任何兩個人之間的平均連結數約為5.5個。「六度分隔」這個說法在約翰·瓜爾1990年的同名話劇以及後來廣受歡迎的「凱文·培根六度」遊戲後廣為人知。

Example Sentences 例句：

• I bumped into my college roommate’s cousin at a conference in Tokyo — six degrees of separation is real! （我在東京的一個會議上碰到了我大學室友的表弟——六度分隔理論是真的！）
• Social media has reduced six degrees of separation to just two or three connections for most people. （社交媒體已經將大多數人之間的分隔度從六度縮減到僅僅兩三度。）
• The concept of six degrees of separation explains why networking is so powerful in business. （六度分隔理論解釋了為什麼人際網絡在商業中如此強大。）

10. Dressed to the Nines｜盛裝打扮

🇬🇧 ความหมาย: Dressed in a very elegant, stylish, or glamorous way. When someone is dressed to the nines, they are wearing their finest clothes and looking exceptionally well-dressed and impressive.

🇹🇼 中文意思： 形容某人穿著非常講究、時尚優雅，盛裝打扮，穿上了最好的衣服，看起來格外體面、令人印象深刻。

Origin 起源： The exact origin of this expression is debated, but several theories exist. One popular explanation is that “nines” refers to a perfect score of 9/10 — the highest rating without being perfect. Another theory points to the Old English meaning of “to the eyes” (eyne in Old English) which sounds like “to the nines.” A third theory suggests it comes from the Scottish poet Robert Burns. The phrase was first recorded in print in 1719, and has been used to describe impeccable dressing since at least the 19th century.

這個表達的確切起源存在爭議，但有幾種說法。一種流行的解釋是「nines」指的是9/10的完美接近滿分的評分。另一種理論指出，古英語中「to the eyes」（古英語中的eyne）聽起來像「to the nines」。第三種說法認為它來自蘇格蘭詩人羅伯特·伯恩斯。這個短語首次見於1719年的印刷文字，至少自19世紀起就被用來形容穿著得體的人。

Example Sentences 例句：

• She showed up to the gala dressed to the nines in a stunning black gown with diamond earrings. （她身穿一件令人驚嘆的黑色禮服，戴著鑽石耳環，盛裝出席了晚宴。）
• It was just a casual dinner, but he arrived dressed to the nines in a three-piece suit. （只是一頓普通的晚餐，但他卻穿著三件套西裝隆重登場。）
• For Chinese New Year celebrations, everyone in our family dresses to the nines. （在農曆新年慶典上，我們家每個人都盛裝打扮。）
