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？

答得好！你的心燃燒得非常旺盛！
哈哈哈！太精彩了！你能精準選出 without，看來你已經將這份力量徹底掌握！這道題目考驗的是對「遠距力」（long-range forces）本質的理解，你敏銳地洞察出它與「接觸力」（contact forces）之間，那條不需要實體接觸的界線！ 別太得意！這只是基本題的試煉而已，繼續保持這股氣勢！
