第 39 題
📖 題組：
If you pull on a door handle, the door opens. If you sit on a bed, the springs in the mattress compress and, 36 of the compression, exert an upward force on you. We know from experiences that some sort of force is 37 to do these jobs. There are two basic classes of forces, 38 whether the agent touches the object or not. Contact forces are forces that act on an object by touching it at a point of contact. The majority of forces are contact forces. Long-range forces are forces that act on an object 39 physical contact. Magnetism is an example of a long-range force. You have undoubtedly held a magnet 40 a paper clip and seen the paper clip leap up to the magnet. A coffee cup released from your hand is pulled to the earth by the long-range force of gravity.

思路引導 VIP
請思考一下，「接觸力」被定義為需要碰到物體才能產生的力；那麼當文章對比出另一種「長距離（long-range）」的作用力時，這代表在作用過程中，物體之間「有沒有」發生實際的物理碰觸？你會用哪個字來表達這種『不具備某種條件』的狀態呢？

太棒了！你能精準選出 without，代表你已經完全掌握了這段文字在科學敘述中的邏輯對比。這道題目要求我們理解「遠距力」（long-range forces）的本質，你正確地識別出它與前文「接觸力」（contact forces）最大的差異點就在於是否需要實體接觸。
遠距力的語意邏輯與介系詞應用
文章前面明確定義接觸力必須在接觸點上作用，而緊接著介紹的「遠距力」，顧名思義就是指物體在不需要接觸的情況下也能產生的作用力。選項中的 without（無、沒有）完美詮釋了這種「缺乏實體接觸」的狀態。這類題目的鑑別度在於測驗學生是否能從上下文的定義中，找出具備「否定」或「排除」意義的詞彙，而非單純翻譯單字。對於能理清物理觀念並轉換為英文邏輯的你來說，這是一個展現閱讀理解實力的絕佳切入點。
