When next year's crop of high-school graduates arrive at Oxford University in the fall of 2009, they'll be joined by a new face: Andrew Hamilton, the 55-year-old provost (教务长) of Yale, who'll become Oxford's vice-chancellor—a position equivalent to university president in America. (09.12 Passage 2)

　　分析主干：they'll be joined by a new face...

　　when...是时间状语从句.主句是被动语态,由by 引出动词join 的发出者a newface,其后的Andrew Hamilton 和the 55-year-old provost of Yale 都是a new face 的同位语。此外，这几个同位语有一个who 引导的非限制性定语从句修饰，定语从句中的名词短语a position equivalent...也是vice-chancellor 的同位语。

　　译文：2009 年秋，当明年的新的一批高中毕业生前往牛津大学就读时，他们将迎来一张新面孔：安德鲁.汉密尔顿。这位现年55 岁的耶鲁大学教务长即将出任牛津大学的副校长—这个职位与美国的大学校长相当。
