选择题
The new means of transport ________ in this city, so whether it will work out remains to be seen.
A．have never tried
B．has never tried
C．have never been tried
D．has never been tried
答案
Ｄ
词义辨析.tried,try的过去时态,意思是尝试/努力.tired形容词意思是累的,疲劳的,根据题意,这个城市中从来没有尝试过新的运输方法,因此它是否这能否实现还有待观察.这里新的运输方式是try的逻辑宾语,故用被动语态,选D.
