The entire country is mountainous, 26 a small strip of subtropical plains in the extreme south.
答案：(C) with the exception of
with the exception of 意為「除…之外」，與 except for 同義：不丹全境皆為山地，只有最南端一小條亞熱帶平原例外；in terms of（就…而言）、as a part of（作為…的一部分）、in accordance with（依照）語意都不合。
exception 你認得名詞「例外」，卻不見得知道 with the exception of 是幾個字合起來當一個介系詞用，功能等同 except for。四個選項都是這種「多字介系詞」，長得像，差別全在它們表達的邏輯關係。
先確認空格的身分。逗號後面接的是名詞片語 a small strip of subtropical plains，不是完整子句，所以要填介系詞，四個選項句法上都過關，要靠邏輯關係決定。接著看主要子句在講什麼：The entire country is mountainous（全境皆為山地）——The entire 宣告的是一個「全部」的敘述。一個句子既然說了「全部」，後面補的那一段自然是把例外扣掉。看到 entire、all、every、no one 這類涵蓋全體的字，就往「排除」的方向找。驗算法：把句子拆成兩句唸一遍——The entire country is mountainous. The small strip of plains in the south is the only exception.（全境都是山地，南端那一小條平原是唯一的例外。）拆得開，就是排除關係。同樣的邏輯 94 年第 25 題也考過一次，那一年給的是 except for，配的線索字是 virtually all；這一年換成 with the exception of，線索字換成 The entire。判斷方式一模一樣：先找宣告全體的那個字。
三個都是多字介系詞，錯在邏輯關係不同。in terms of 是「就…而言」，用來限定討論的角度（in terms of cost 就成本而言），本句不是在切換角度。as a part of 是「作為…的一部分」，會讀成「平原是山地的一部分」，但平原與山地正是相對的兩種地形，自相矛盾。in accordance with 是「依照」，後面接的是規定、法律或標準，一片平原不是可以依照的東西。
with the exception of（除…之外）、except for（除…之外）、without exception（無一例外）、make an exception（破例）、in terms of（就…而言）、in accordance with（依照）。
