题目内容
14.The laptop _____ in Japan in 1985.It is used for studying.( )| A. | is developed | B. | was developed | C. | developed |
分析 便携式笔记本电脑是1985年在日本开发的.它是用来学习的.
解答 答案:B.根据题干,可知主语The laptop 是动作develop的承受者,和动词构成被动的关系,应该用被动语态,表示"电脑被开发".被动语态的结构是"be+过去分词";根据句中的in 1985可知,应该用一般过去时.一般过去时态的被动语态的构成:was/were+及物动词的过去分词;laptop是单数,应用was.故选B.
点评 主要考查被动语态,当句子的主语是动作的承受者时,应该用被动语态,本题考查的是一般现在时态的被动语态.一定要注意:一般过去时态的被动语态的构成:was/were+及物动词的过去分词,以及动词过去分词的形式.
