Question

Mr. Sawyer started his career at Stanford University _____ he became Professor of Physics in 2002.

A. which B. where C. when D. that

Answer 1

B

分 析：
考查非限制性定语从句。先行词是at Stanford University，定语从句主谓宾都有。结合句意可知缺少地点状语，故用关系副词where来引导从句，修饰限制at Stanford University。句意：索耶先生在斯坦福大学开始他的职业生涯，他在 2002 年成为斯坦福大学的物理学教授。故选B。
考点：
考查非限制性定语从句。
