【解析】试题分析:句意:据报道,吸烟者人数仅(过去)一年就减少了17%。as引导的非限制性定语从句位置灵活,可以置于主句的句首、句中或句末,指代的是整个一句话。故选D项。考生容易误选B项which,把逗号前面的the number of smokers看成先行词,后面非限制性定语从句用which引导。殊不知,这里关系代词指代的是“The number of smokers has dropped by 17 percent in just one year.”整个一句话。另外,as和which在定语从句都可以指代一句话,但前者有“正如……”的意思,后者则没有。还可以抓住as is reported这一常用结构,类似的还有as is known/expected/planned/mentioned/said等。
【考点定位】定语从句
