19题的正确句子是:The exploits of Nellie Bly, a pioneer journalist, included circling the globe faster than Jules Verne’s fictional Phileas Fogg.
47题的正确句子是:In 1713, Alexander Pope began his translation of the Iliad, a work that took him seven years to complete and that literary critic Smauel Johnson, Pope’s contemporary, pronounced the greatest translation in any language.
这两道题的考点都是A of B, ....(解释性的从句或者名词),但是为什么19题的a pioneer journalist修饰的是B(即Nellie Bly),而47题的a work that took him seven years to complete修饰的是A of B (即his translation of the Iliad)?
