Question

—________ does it take you ________ home every day? — About half an hour.

A.How often; to walk B.How long; to walk to

C.How often; to walk to D.How long; to walk

Answer

D

【解析】

句意：——你每天走路回家要花多长时间？——大约半个小时。

考查特殊疑问句和“动词+副词”短语。How often多久一次，对频率提问；How long多长，对时长或长度提问。根据答语“About half an hour.”可知，此处是对时长提问，排除A和C。分析第二处可知，home是副词，此处构成“动词+副词”短语，home前不需加介词。故选D。
