1.Earthenware has an advantage over wood in being more easily kept clean. 被动语态。 该句考查的是被动语态,由句中的be + 过去分词可知。2.Perhaps he had followed her suggestion of a stroll at the river. stroll的意思是“闲逛”,stroll at swh.意为“在某地游玩”。如A Stroll at Strasbourg可翻译为“漫步斯特拉斯堡”。第二个空的介词填空,你还是看看题目来源处的答案吧,我想想,是不是填along(沿着)活着to(到)都行呢?呵呵,祝你学习进步!
