According to scientists, personal space involves certain invisible forces imposed on you through all the 12.
答案：(C) senses
through all the senses（透過所有感官）呼應後文 unwelcome sound, smell, or stare（不受歡迎的聲音、氣味或注視），表示個人空間受侵犯的感受是透過各種感官傳達的；angles／events／regions 均不符合此處語意。
invisible forces（看不見的力量）這個說法很抽象，讀起來像在講方位或範圍，所以 angles（角度）與 regions（區域）都顯得說得通——力量從各個角度加在你身上，讀起來很順，於是就填了。
四個選項都是名詞複數、都接在 through all the 後面，文法上都放得進去，可見這一格考的是語意，落在大考中心說的「詞彙量」這一項上。定案的線索完全在下一句：For example, people may feel their space is being invaded when they experience an unwelcome sound, smell, or stare.（不想聽到的聲音、不想聞到的氣味、不想被盯著看的注視）。聲音、氣味、注視分別對應聽覺、嗅覺、視覺，三樣並列的東西同屬一類，就是感官。上一句說那些看不見的力量是 through all the ______ 加在你身上的，下一句立刻用三種感官把它拆開來舉例，所以空格填 senses。這一題只讀空格所在的那一句是定不了案的：through all the angles 讀起來也不算不通。For example 是最好認的邏輯勾環，看到它就要回頭與前一句對齊——舉例句是用來說明前一句的，前一句抽象在哪裡，例子就在補哪裡，反過來就是最可靠的線索。
angles（角度）與 regions（區域）都是空間概念，但下一句舉的三個例子沒有一個與方位有關。events（事件）指的是發生的事，聲音、氣味、注視都不是事件，而且 through all the events 會變成「透過所有事件」，與 imposed on you（加諸在你身上）接不起來。三個選項的問題其實是同一個：只要真的把下一句讀進來，沒有一個接得住。
through the senses（透過感官）、impose something on somebody（把某事強加在某人身上）、invade（侵犯、入侵）、be violated（被侵犯）、an unwelcome sound（不受歡迎的聲音）、for example（舉例來說）
Have you been irritated by someone standing too close in line, talking too loud or making eye contact for too long? Or, they may have 11 you with the loud music from their earphones, or by taking up more than one seat on a crowded subway car. You feel unhappy because your personal space has been violated.
According to scientists, personal space involves certain invisible forces imposed on you through all the 12. For example, people may feel their space is being invaded when they experience an unwelcome sound, smell, or stare.
In certain situations such as in crowded subway cars or elevators, it is not always possible for people to keep their 13 distance from others. They learn coping strategies to deal with their discomfort. For instance, people often avoid eye contact with someone standing 14 them, or they pretend that these people are lifeless objects in their personal space. Given the opportunity, they may 15 to a corner, putting distance between themselves and strangers. Or, they may sit or stand equidistant from one another like birds on a wire.
