　參考答案&解析：

　　1、C　obscure(=not clearly seen or understood)模糊難懂得。drastic激烈的，嚴(yán)厲的;dull單調(diào)的;distinct清楚的，明顯的;截然不同的(from)。本題譯文：她提到她的朋友----詩人時(shí)所說的話是令人感興趣，但沒有說清楚，以致沒有人為此感激。

　　2、C　break off(=cease suddenly, discontinue)突然中斷;break off one's engagement(解除婚約)。Break off(=interrupt) one's conversation(打斷談話)。Break out(=begin suddenly)爆發(fā)。Break away from擺脫，從......退出。

　　3、A　indispensable(to, for)不可缺少的，必需的。Indicative(of)指示的。Inevitable 不可避免的。Inherent固有的，內(nèi)在的，天生的。
