15.Welcome to the Science Museum,everyone!This stone axe _______ in South Africa and experts can't be exactly sure about its use.( )A. | had been found | B. | was found | C. | has been found | D. | would be found |
分析 欢迎大家来到科学博物馆,这把石斧是在南非发现的,专家们不能确切地知道它的用途..
解答 答案是B.考查被动语态,this stone axe是句子的主语,与动词find之间是被动关系"被发现",根据题干信息可知,石斧现在摆在博物馆,发现应该是过去时,所以答案选B.
点评 被动语态由"助动词be+及物动词的过去分词"构成.被动语态的时态变化只改变be的形式,过去分词部分不变.疑问式和否定式的变化也如此.掌握各种时态的被动语态是解题的关键.
