BBC News reported that President Trump said a US-Iran deal would be signed on Sunday, while Tehran questioned that timing. The BBC RSS summary said Iran had not confirmed an exact date and said it “will not be tomorrow.”
For English learners, the item is useful because diplomatic reporting often uses careful verbs and phrases—such as casts doubt, timing, and exact date—to show uncertainty without using emotional language.
BBC News 報導，川普表示美國與伊朗的協議將於週日簽署，但德黑蘭方面對這個時間點提出疑問。BBC 的 RSS 摘要指出，伊朗表示尚未決定確切日期，並稱「不會是明天」。
這則新聞適合學習外交新聞英文，因為報導常用精準而克制的詞語，例如 casts doubt（使人懷疑）、timing（時間安排）與 exact date（確切日期），來表達不確定性。
