Question

--- How does your mother go to work ?

---She usually           because her office is not far.

A. go to work on foot   B. walks to work

C. takes a plane     D. takes a train

Answer

B

【解析】

试题分析：句意：-你妈妈怎样去上班？-她通常走路去上班，因为她的办公室不远。go to work on foot步行去上班；walks to work走路去上班；takes a plane乘坐飞机；takes a train乘坐火车。根据句意because her office is not far可知C和D不对。这句话的主语She是第三人称单数形式，故选B。

考点：考查动词短语。
