Question

– Could you tell me where I can get a dictionary?

– Take the escalator. The bookstore is on the ________ floor of the 5-floor building.

A. firstB. thirdC. ninth

Answer

B

【解析】

试题分析：A. first第一，B. third第三，C. ninth第九。Take the escalator.乘电梯，一楼不用乘电梯。又根据5-floor building.五层的建筑物，所以没有第九层。几层用序数词表示。句意：你能告诉我我在哪里能拿到字典吗？坐电梯，书店在三楼。故选B。

考点：考查序数词的用法。
