A. 狩猎社会与农耕社会的主要区别是什么。based 做后置定语,相当于省略了(which were)。
D. 全国的医疗及公共卫生专家们都全力以待以应对随时可能发生的意外事故。句子中没有明确的时间指示,根据句意可判断,不是讲过去的事,B排除。C表被动,也排除。句子表示专家们直到现在为止一直都严阵以待,随时奉命行事,所以选D,现在完成进行时。而A表示已经完成了,事故随时可能发生,那专家就没完成任务呢,所以也排除。 (这句话应该指的是一些突发的情况,比如地震或是其他有人员伤亡的突发灾情。)
追问
base这个词是只能用于被动语态么?没有主动语态?
追答
应该也有的。比如,我随便举个例子,Basing on the whole perspective of the nation, I think China still has a long way to go before it truly becomes a global power. 表示基于一种状况或情形,我表达了一种什么观点...,做条件状语。 其实,这句话也可说成,I think China still has a long way to go before it truly becomes a global power basing on the whole perspective of the nation. 你题目中的例子based做的是定语,相当于形容词;而做状语时,相当于副词。(不知这样理解可否。)
