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。
答對率 23%。
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。
The entire country is mountainous, ___ a small strip of subtropical plains in the extreme south.——前半用了 The entire country（全境），是一個「全部」的敘述，後面接的自然是例外。「看到 entire、all、every 這類表全體的字，就往「排除」的方向找。」
in terms of 是「就…而言」（in terms of cost）；as a part of 會變成「平原是山地的一部分」，自相矛盾；in accordance with 是「依照」，用於規定或程序。
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）。
