At the moment EU tobacco manufacturers only have to put written health warnings on cigarette packets 24 the dangers of smoking.
答案：(C) highlighting
現在分詞片語 highlighting，補充說明健康警示的作用「強調吸菸的危害」；highlight（原形動詞，不能這樣修飾）、highlights（限定動詞，句子已有主要動詞have to put）、highlighted（過去分詞，被動語意方向不合，應該是警示「強調」危害不是「被強調」）都不合。
答對率 47％，一半的人填錯，鑑別度也只有 35，高分群考生失守的不少。最常見的失手是被前面的 written 帶走：同一個名詞前面剛用過一個過去分詞當形容詞（written health warnings），眼睛看熟了，輪到空格時手就自動再選一次過去分詞 highlighted。越注意到 written 的人，越容易掉進這個對稱的陷阱。
四個選項是同一個動詞的四種形態（與同卷第 16 題同型），可見這一格考的是形態不是字義。兩步就能定案。第一步，這句已經有主要動詞 have to put，空格再放一個有時態的動詞，就會變成一句話裡兩個主要動詞卻沒有連接詞，所以 highlight 與 highlights 一起刷掉。第二步，剩下的 highlighting 與 highlighted 都是分詞，都能擺在名詞後面當修飾語，差別在主動被動：空格後面還跟著受詞 the dangers of smoking——被動之後不能再接原來的受詞，這是學測反覆出現的鐵律（同型：100 年第 19 題 being wrapped the body、95 年第 27 題 is attracted those fans）。所以只能用主動的 highlighting，還原成子句就是 warnings which highlight the dangers of smoking（凸顯吸菸危害的警語）。
highlight（原形）：既不能當這句的主要動詞，也不能單獨擺到名詞後面當修飾語。highlights（第三人稱單數）：同樣是有時態的動詞，會造成一句兩個主要動詞。highlighted：警語是主動去凸顯危害，不是被危害凸顯；掛回國中就學過的對照 a barking dog（會叫的狗，主動）與 a broken window（被打破的窗，被動），一個是自己往外做，一個是被做。
highlight the importance of（凸顯……的重要性）、draw attention to（引起對……的注意）、point out（指出）、at the moment（目前）、have to V（不得不、必須）、the dangers of（……的危險）。
