To tulip, 我想应该是单数. 我在看jj的时候也注意到这个问题了, 特意搜索了大全. SC, CR里都没有, RC有一些. GRE阅读: A series of observations is presented and explained in terms of the dominant theory. A series of examples is presented, and a conclusion is drawn. LSAT阅读: A series of events that range from the real to the depicted conveys the contrast between real events and cinematic depiction. A series of hypotheses is reviewed and one is advocated. 当然也有反例: LSAT阅读: A series of evaluations are given, concrete reasons are put forward, and a future direction for research is suggested. 上述的例句大多出现在选项中, 也就是说这些句子应该都是出题机构写的, 应该能够反映出题机构的语言习惯. 单数4次, 复数1次, 单数胜!!  |
