on holiday 还是on holidays

on holiday 还是on holidays

到底是 on holiday 还是on holidays？其中的 holiday 到底该用单数还得复数？

_________ the railways put on special trains.

A. In holiday            B. On holiday          C. In holidays          D. On holidays

现分析如下：

大家知道，on holiday是习语，意为“在休假”，该短语通常用介词 on 而不用 in，且其中的holiday 通常不用复数，且其中也不用冠词，但有时可用物主代词 (此时可用复数，即 on one's holidays)。基于此认识，许多同学便选了B。

其实此题最佳答案为D，on holiday 和 on holidays 均可用说，只是含义不同：

1. 短语 on holiday，可用作表语或状语，其中通常不用冠词，但有时可用物主代词。如：
