分析 当导游在介绍长城的历史时,与此同时一些游客在拍照.
解答 答案:B
结合语境并根据句中提到的时间状语从句"While the tour guide was introducing the history of the Great Wall"可知使用的是过去进行时态,表示在过去某个时间正在进行的动作,在结合句中的 at the same time"与此同时"可知表示在过去那个时间段同时正在进行的动作,故也用过去进行时,过去进行时的构成为:was/were+现在分词,主语some tourists 是复数,故使用were,故选B
点评 本题考查过去进行时,该时态表示在过去某个时间正在进行的动作,构成为:主语+was/were+现在分词
