--_____ of the population of the city _____workers?
--About 60 percent.
A.What; isB.What; areC.How much; isD.How much; are
D
考查population的用法。對(duì)人口“提問(wèn)”,用what來(lái)問(wèn)總?cè)丝;how much問(wèn)的是“多少(比例)”。句意“這個(gè)城市人口的多少比例是工人?”“大約60%!眕opulation作主語(yǔ),謂語(yǔ)用單數(shù),但是指具體的人數(shù)時(shí),謂語(yǔ)用復(fù)數(shù)。故選D。
