Question

About 85％ of per cent of the cases of blindness in that place buy the orbis A are prevent
B were prevent C is prevent D was prevent
那如果是 85％ of per cent the of lands of the world 后是用is 还是are

Answer 1

About 85 percent of the cases of blindness in that place are prevented by the orbis.
那个地方大约85%的失明病例/状况得到了国际奥比斯组织的有效预防.
含有分数时谓语要跟of 后的名词保持一致,因为the cases是复数,又是介绍现在的状况,所以用一般现在时的被动语态,故选A.are prevented.
