第 37 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：當我們提到為了達成某個特定的結果（例如讓門打開），某個因素（例如「力」）是「絕對必須存在」的前提時，在英文語法中，我們會如何描述這個因素與目標之間的『必要性』關係？

語境邏輯與動詞辨析
非常好！你精準地捕捉到了句子中的邏輯關聯。這題考查的是動詞在科學描述中的語境搭配。文中先舉出「開門」與「床墊受壓」等實例，接著指出這些動作（jobs）的達成，前提是必須有某種力的存在。在這種「因果與條件」的論述中，我們需要一個表示「必要」或「需求」的詞；而 required（被需要、必須的）正符合這種被動語態的表達，清楚說明了「力」是完成這些物理現象不可或缺的先決條件。
