Question

【题目】Mr. Li goes to work ___ bus, but sometimes he ___ the train.

A. On; take B. by; by C. by; takes D. take; takes

Answer 1

【答案】C

【解析】句意：李先生坐公交车去上班，但是有时他乘坐火车。by bus乘坐公交车，作状语；take a /the bus乘坐公交车，作谓语；by train乘坐火车，作状语；take the train乘坐火车，作谓语。第一空作状语修饰动词短语go to work，故用by bus。故排除AD两项。第二空作谓语，故用动词短语takes the train。故选C。
