问题 Annie Jump Cannon, leader astronomer discovered so many stars that she was called "the census taker of the sky."

选项 A、a leading astronomer,
B、a leading astronomer who
C、was a leading astronomer,
D、who, as a leading astronomer

答案 A

解析 本题重点考查同位语的用法。画线部分是句子主语的同位语,补充说明主语的身份,但是却是由两个名词组成,一个表示职位,一个表示职业,leader不能修饰astronomer,而且缺乏冠词,因而是错误的。四个选项中首先可以排除B和D选项。B和D选项中有一个who引导的定语从句,这样整个句子就没有谓语动词。C选项中有一个谓语动词was,与另一个谓语动词discovered冲突,违反一个句子通常只有一个谓语动词的惯例。故选A,名词词组正确地表达出与主语的同位关系。
