A person's self-concept is reflected in the way he or she behaves, and the way a person behaves affects other people's reactions. 21 , the way people think about themselves 22 a profound effect on all areas of their lives.
答案：(D) has
句子主詞的中心詞是單數名詞 the way（the way people think about themselves），動詞需用單數 has，不受插入的複數 people 影響。have 用於複數主詞，having／to have 不是限定動詞，不能單獨作句子主要動詞。
本題大考中心未公布逐題答對率，以下不談數據，只談觀念。
空格前面緊挨著的是 themselves，再往前是 people，都是複數，很容易就選了 have。這一格的陷阱正是「離動詞最近的名詞不一定是主詞」。
先把主詞找出來，不要被中間那一串干擾。整個主詞是 the way people think about themselves（人們看待自己的方式）——中心語是 the way，是單數；people think about themselves 只是修飾 the way 的關係子句（完整的說法是 the way in which people think about themselves）。主詞既然是單數的 the way，動詞就要用單數的 has。掛鉤是國中就見過的句型：The book on the desk is mine.（桌上那本書是我的。）——主詞是 book 不是 desk，中間那個介系詞片語不會改變主詞。本題只是把介系詞片語換成關係子句，道理完全一樣。判斷方式相同的題目：86 年第 39 題 →的主詞是 Much of your success（Much 當單數），中間也插了一長串 both in your work and social life。看到主詞與動詞被一長串隔開，第一件事就是把中心語找出來。
have：複數形，會被中間的 people 誤導，這是本題最強的陷阱。having：現在分詞，不是限定動詞。to have：不定詞，同樣不能當句子的主要動詞。
