Much of your success, both in your work and social life, 39 how you listen.
答案：(A) is related to
主詞 Much（不可數、視為單數概念）需要搭配單數動詞，且語意是「你的成功與你怎麼聽有關」，is related to（與……有關）方向正確；has an impact on 雖然也是單數動詞形式，但語意方向相反（暗示成功影響聽力，而非聽力影響成功）；have a lot to do with／are of great importance to 則是複數動詞形式，不符合單數主詞 Much。
本題大考中心未公布逐題答對率，以下不談數據，只談觀念。
四個選項的中文都能翻成「與……有關、對……有影響、很重要」，光比意思會覺得好幾個都行。這一格先看主詞是單數還是複數，一步就刷掉一半。
先找主詞：Much of your success, both in your work and social life, ___ how you listen.主詞是 Much（很大一部分），是不可數的概念、當單數看；中間 both in your work and social life 是插進來的補充，不影響主詞。既然主詞是單數，動詞就要用單數形——have a lot to do with 與 are of great importance to 都是複數形，直接出局。這一招很快，而且完全不必想語意。剩下 is related to 與 has an impact on，這時才比語意方向：本句要說的是「你的成功有很大一部分與你怎麼聽有關」，是聆聽影響成功；而 has an impact on 會變成「你的成功對你怎麼聽有影響」，因果整個顛倒。所以填 is related to。
have a lot to do with、are of great importance to：意思都對得上，但主詞是單數，動詞形態不合，這是最快能刷掉的兩個。has an impact on：形態沒問題，但因果方向相反。
be related to（與……有關）、have a lot to do with（與……大有關係）、have an impact on（對……有影響）、be of great importance to（對……非常重要）、much of（……的很大一部分）、social life（社交生活）。
