These bacteria are found in the nose and are easily 18 to the eye when you rub your nose, then your eye.
答案：(D) transferred
語意「這些細菌很容易『被傳播』到眼睛」，transferred（被傳播/轉移）符合，揉鼻子再揉眼睛時細菌被帶過去；attracted（被吸引）、contributed（貢獻）、exposed（暴露，不太符合「傳播到」這個動作）都不合。
看到空格後面是 to the eye，你腦中第一個跳出來的一定是 be exposed to（暴露於、接觸到），因為這是背過的高頻搭配。這正是本題最大的陷阱：be exposed to 的主詞是「被暴露的那一方」，例如 Your skin is exposed to sunlight（你的皮膚接觸到陽光）；但這句的主詞是 These bacteria（這些細菌），細菌是「被帶過去的東西」，方向剛好相反。
用主動句還原一次就清楚了。主動：When you rub your nose, then your eye, you transfer the bacteria to the eye.（你揉鼻子再揉眼睛，就把細菌帶到眼睛去了。）改成被動，主詞換成細菌：These bacteria are easily transferred to the eye.（這些細菌很容易被帶到眼睛。）transfer 是「從一處移到另一處」，正好對應「從鼻子到眼睛」這個路徑。字首也能幫你確認：trans- 表示「橫越、轉移」，同一個字首家族的還有 transport（運輸）、translate（翻譯，把意思從一種語言搬到另一種）、transform（轉變）。
attracted to（被……吸引）語意不合，細菌不是被眼睛吸引過去的。contributed to（造成、促成）後面接的是結果，像 contribute to global warming（造成全球暖化），不能接地點。exposed to 如前所述主詞方向錯了。
transfer A to B（把 A 移轉到 B）、be transferred to（被轉移到、被調到）、be exposed to（暴露於、接觸到）、contribute to（造成、促成；捐助）、be attracted to（被……吸引）、build up（累積、增強）。
You begin to notice a bit of pain on your eyelid each time you blink. You 16 the mirror to find a tiny red spot on the base of your lower lashes. These 17 are probably the beginning of an eye stye.

19 a stye can look unpleasant at times, it is usually harmless and doesn't cause vision problems. Most styes heal on their own within a few days. You might speed up healing time by gently pressing a warm washcloth 20 your eyelid for 10 minutes, 3 or 4 times a day. Make sure you don't squeeze or pop a stye like you would a pimple. Doing so may cause a severe eye infection.
