用法說明
How is "Sign" different from similar structures?What usage mistakes are common with "Sign"?
sign doing vs sign to do
- sign doing 通常用於描述簽署一份具體、已存在的文件或合約，強調簽署的對象是某個「東西」。
- sign to do 則用於表示簽約是為了進行某個未來的「行動」或達成某個目的，強調簽約的意圖或後續動作。
- 當主詞是機構或公司時，sign to do 也常用來表示簽下某人（如運動員、藝人）來執行某項任務。
- 在表示「簽名同意做某事」的意願時，特別是與 would 或 agree 連用，通常使用 sign to do 的結構。 EN: The CEO signed the merger agreement yesterday. 翻譯: 執行長昨天簽署了合併協議。
EN:The rookie signed to play for the team for three seasons.
翻譯:這位新人簽約為該球隊效力三個賽季。

正式書寫注意：在正式書面文件（如合約、報告）中，應避免使用上述口語引述或填充停頓的用法，應直接明確地陳述簽署方與簽署行為，例如：「甲方應於此處簽署」而非口語化的「你得在這裡簽名」。

常見錯誤
What are common mistakes with "Sign"?Which "Sign" sentences look correct but are wrong?
×Please put your sign here.
✓Please put your signature here.
"sign" 作為動詞是「簽名」，但作為名詞時，通常指「標誌、跡象、手勢」。表示「簽名」的名詞是 "signature"。
×I want to sign in for the new course.
✓I want to sign up for the new course.
"sign up for" 表示「報名、註冊」某項活動或服務。"sign in" 或 "log in" 是指已經有帳號後「登入」系統。
×We signed the deal.
✓We signed the contract / agreement.
雖然口語中可能聽到 "sign a deal"，但更正式和常見的用法是 "sign a contract" 或 "sign an agreement"。"Deal" 本身是「交易」，簽署的是具體的「合約」文件。
×He signed.
✓He signed the document. / He signed his name.
動詞 "sign" 通常是及物動詞，需要接賓語（如文件、名字）。除非上下文非常清楚（例如在說「他簽名了」），否則單獨使用 "He signed" 會顯得不完整。
×They communicate by sign language.
✓They communicate by sign language. / They communicate using sign language.
這個錯誤在於冠詞的使用。"Sign language" 作為一種語言名稱，通常是不可數名詞，前面不加冠詞 "a" 或 "the"，除非特指某一種手語（如 "American Sign Language"）。原句 "by sign language" 其實是正確的，但學習者常誤加冠詞。正確對比應為："by sign language"（正確） vs "by a sign language"（錯誤，除非特指）。
×Dark clouds are a sign for rain.
✓Dark clouds are a sign of rain.
表示「…的跡象、徵兆」時，固定搭配是 "a sign of something"，使用介系詞 "of"，而不是 "for"。"For" 通常用於表示目的或對象，例如 "a sign for drivers"（給駕駛看的標誌）。
