[译] 我向一个交警打听上车站的路。
[误] I inquired a traffic policeman the way to the station.

[正] I inquired the way to the station of a traffic policeman.
[注] inquire 意为“询问，打听”，容易使人联想 ask 而错误地使用类似 ask sb. a question 的结构。inquire 不能接双宾语，而且不能直接以人作宾语，而常使用 inquire sth. of sb. 或 inquire of sb. about sth. 的结构。又如：I inquired of him aboutthe schedule. 我向他询问计划的情况。
