--Excuse me. Could you tell me to Xi’an Expo?
--Take No.231 to get there.
A. which bus should I take
B. how far is it
C. which bus I should take
D. how far it is

A. which bus should I takeB. how far is it(答案→)C. which bus I should takeD. how far it is解析：宾语从句的结构：主语+谓语+连接词+从句。从句在句中作宾语。从句要用陈述句的语序。如果主句是一般现在时，从句根据需要选择时态，如果主句是过去时态，从句要用相应的过去时态。但是从句是客观真理，一般用一般现在时态。该句主句是一般现在时，从句根据需要用一般现在时。AD是疑问句语序，故排除。根据回答乘坐231路到那里。故引导词是which bus,那辆车。故选C。
