多选题
Some critics of congressional proceedings contend that important debates on issues are marred by a ______ of denunciations and accusations that precludes ______ discourse.
【正确答案】
B、E
【答案解析】[解析] ●marred表示“被玷污”,说明前后出现反义对比。
●debates和discourse同义重复,与denunciations and accusations反义对比。因此第一空填入负评价,第二空填入正评价。
●paucity少量,cacophony刺耳的声音,rehash重复;expendable不必要的,orderly有条理的,libelous诽谤的。答案选BE。
