单选题 He is ______ drinker, who has been imbibing for so long that he has figuratively speaking, grown old with the vice.
A. an inveterate B. an incorrigible C. a chronic D. an unconscionable

【正确答案】 B
【答案解析】[解析] 本句的意思是“他是个无药可救的酒鬼，酒龄这么长，以致他都形象地说他将和恶习一起变老”。incorrigible意为“无药可救的”，如：an incorrigible criminal(一个不可挽救的罪犯)。其他三项“inveterate成癖好的；chronic慢性的；unconscionable不合理的，过度的”都与句意不符。
