To read Tolstoy and ________ to nineteenth century Russian literature are two excellent reasons for taking Professor Morrel’s course．

A.to introduce

B.introduce

C.being introduced

D.be introduced

试题答案

D

句意是“能够阅读托尔斯泰的小说，并且对19世纪俄国的文学得到了解是我上墨里尔教授的课程的两个主要原因”。To read Tolstoy and be introduced是两个不定式作并列主语，第二个不定式省略了to。要注意introduce与说话者是被动关系，所以要用不定式的被动语态。
