We are in general insensitive to architecture 16 an art and to the joy it may bring to us.
答案：(A) as
insensitive to architecture as an art（對建築作為一門藝術感到遲鈍）表示我們普遍對「建築身為一門藝術」這件事不夠敏銳；or／of／like 均不符合此處以身分／角色解讀 architecture 的語意搭配。
本題大考中心未公布逐題答對率，以下不談數據，只談觀念。
四個都是最常見的功能詞，看起來哪一個都塞得進去；like 特別誘人，因為「把建築當成像藝術一樣」讀起來也很順。
先看整句的結構：insensitive to architecture ______ an art and to the joy it may bring to us。第二個 to 前面有 and，可見 insensitive to A and to B 是並列的兩項，所以空格那一段是掛在 architecture 後面說明它身分的修飾語，不是另起一個並列項。而它的身分，篇章第一句已經講死了：Architecture is an art.。這正是介系詞 as 的「以……的身分、當作」用法，還原成子句就是 architecture, which is an art。
like 是「像……一樣」，言下之意是「其實不是」，與第一句 Architecture is an art. 直接衝突——文章的立場是建築就是藝術，不是像藝術。of 表所屬或性質（a man of honor），architecture of an art 講不通。or 是對等連接詞，會把 an art 變成與 architecture 並列的另一樣東西，但這一句只在講一樣東西。
as ＋ 名詞（以……的身分、當作）、be insensitive to（對……無感、不敏銳）、regard A as B（把 A 視為 B）、bring joy to somebody（為某人帶來喜悅）、in general（一般而言）、like ＋ 名詞（像……一樣）
Architecture is an art. Any art must give us pleasure; if it doesn't, either it is bad art or we are abnormally blind. We are in general insensitive to architecture 16 an art and to the joy it may bring to us. It is the constant nearness of architecture during our life that has 17 us in this way.
We forget that it is an art of here and now; because it is with us every day and 18 we must have houses to live in, we are apt to think of them solely as dwelling places. Therefore we think of architecture as some vague, learned thing having to do with French cathedrals or Italian palaces or Greek temples, 19 with New York or Chicago streets or Los Angeles suburbs.
This false belief has strengthened in us until our eyes are 20 and our minds are deadened to all the beauty that is being created around us today. Eventually we lose all the fine deep pleasure that we might otherwise experience from our ordinary surroundings.
