题目内容
9.-Could yon tell me whom the radio ______ by?-Sorry,I have no idea.( )| A. | invents | B. | invented | C. | is invented | D. | was invented |
分析 --你能告诉我收音机是谁发明的?--对不起,我不知道.
解答 答案D
根据句中询问收音机的发明者结合常识可知动作发生在过去,可判断句子为一般过去时,主语radio是谓语动词invent 的承受者,二者是被动关系,故用被动语态,所以空处为一般过去时的被动语态,一般过去时的被动语态的结构为was/were+及物动词的过去分词. 故选D
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,本题考查的是一般过去时态的被动语态.一定注意其构成形式,一般过去时的被动语态的构成:was/were+及物动词的过去分词
