- forecast doing 通常用於描述預測一個持續進行的狀態或活動，強調過程或趨勢。

引述
在口語中，當引述或轉述他人的預測時，常用「forecast」來保持客觀性。 EN: He forecast that the project would be delayed by a month. 翻譯: 他預測這個專案會延遲一個月。

EN:So, forecasting the budget needs for next year... we'll probably need more staff.
翻譯:所以，預測明年的預算需求... 我們很可能需要更多人手。

常見錯誤
What are common mistakes with "Forecast"?Which "Forecast" sentences look correct but are wrong?
×The weather forecast will rain tomorrow.
✓The weather forecast predicts rain tomorrow.
「forecast」作為名詞時意為「預測、預報」，不能直接當動詞使用來表示「預測會發生某事」。應使用動詞「forecast」或「predict」等來表達預測的動作。
×Yesterday, they forecasted sunny weather.
✓Yesterday, they forecast sunny weather.
動詞「forecast」的過去式和過去分詞可以是「forecast」或「forecasted」，但「forecast」更為常見且被視為標準形式，特別是在正式或專業語境中。使用「forecasted」有時會被視為不自然或錯誤。
×It is difficult to forecast accurately.
✓It is difficult to forecast the weather accurately.
動詞「forecast」通常為及物動詞，需要接一個受詞（如 the weather, the result, sales）來表明預測的內容。除非上下文已非常清楚，否則不應單獨使用。
×They forecast a storm on the weekend.
✓They forecast a storm for the weekend.
當「forecast」用於預測未來某個特定時間會發生的事件時，指示時間通常使用介系詞「for」，而不是「on」或「in」。使用「for」來指向預測事件發生的時間段。
×I forecast that you will pass the exam.
✓I predict that you will pass the exam.
「forecast」通常用於基於數據或專業分析的正式預測（如天氣、經濟、趨勢），語境較客觀。對於個人主觀的猜測或預言，使用「predict」更為自然。在此例句中，用「forecast」顯得不自然且過於正式。
