(2013·山东济宁模拟)New computers are soon out of date since newer models are ________ constantly.
A.turned up B.turned out
C.turned down D.turned over
▼优质解答
答案和解析
B

B 句意:由于更加新型的电脑不断地被生产,新电脑很快就会过时。A:出现;C:拒绝;D:翻身,翻转。turn out为及物动词短语,意为“生产或制造某物”。newer models与turn out为被动关系,故需用被动语态。本题易误选A项,但turn up作“appear(出现)”讲时为不及物动词短语,没有被动语态。
