题目内容
9.---When _____ the first train _______?---In 1825.( )| A. | was; invented | B. | did,invent | C. | was; discovered | D. | is; found |
分析 -第一列火车是什么时候发明的?-在1825年.
解答 正确答案:A.invent是发明.discover是发现.find(found是其过去分词)找到.根据常识可知第一列火车肯定是"发明"的,所以排除CD选项.其次train和invent是被动关系,指被发明,需用被动语态(be+动词过去分词).最后由答语in 1825可知其火车是在过去发明的,所以需用一般过去时的被动语态(was/were+动词过去分词),故答案是A.
点评 本题考查一般过去时被动语态及动词词义辨析,首先清楚动词含义,其次根据主谓关系判断"语态",最后根据时间状语判断"时态"即可作出选择.
