问题 Many economists believe that America must replace its moribund smokestack industries with business based on new technology.
选项 A、obsolete
B、mordant
C、mortified
D、ousted
答案 A
解析 moribund意为“濒死的，奄奄一息的，停滞不前的”。A选项：obsolete意为“过时的，废弃的”，与画线单词的意义相符，如：So much equipment becomes obsolete almost as soon as it’s made．这么多设备几乎一生产出来就会被淘汰。故选A。在其他三项中，B选项：mordant尖酸刻薄的，尖锐的；C选项：mortified感到羞辱的，窘迫的；D选项：ousted驱逐，罢黜，都与画线单词的意义不符。
