题目内容
18.Who can tell me when______?( )A. | the telephone is invented | B. | the telephone was invented | ||
C. | is the telephone invented | D. | was the telephone invented |
分析 谁能告诉我电话是什么时候发明的?
解答 答案:B 根据选项内容可知考查宾语从句,宾语从句中一般为陈述语序,排除CD;又因为"电话的发明发生在过去","电话"做主语,电话是物,是被发明的,所以用一般过去时态的被动语态;一般过去时态的被动语态的结构为:was/were+动词的过去分词.telephone为单数,所以用was.故选B.
点评 本题考查宾语从句,做题时注意宾语从句三要素时态、语序和连接词.本题注意时态和语序.
