Tuberculosis has long been ___ and ___ disease: for thousands of years, it has continued to afflict humankind without regard for sex, class, occupation, or race.A. an unremitting...selective
B. an unpredictable...limitable
C. a sporadic...capricious
D. a relentless...egalitarian
E. a virulent...preventable
sporadic的原型是希腊文sporadikos, 义为here and there。既是时间上的间歇性发作又可以是空间上的零星分布「因为时间本质上也是一种空间」。sporadic对应后面的capriciious,虽然不一定非要是同义,但相近总归好点。 relentless和egalitarian没有意义上的相近关系。当然现实生活中你写relentless和egalitarian都是没错的,但要讲语言精确度的话,还是用相近相同来并列叭。
