18. Once the economic and social usefulness of the motor car was demonstrated and with its superiority to the horse being proved, much of the early hostility to it in rural regions disappeared.
B. and its superiority over the horse had been C. and its superiority to the horse
白勇解释: C选项,and 连接once从句和名词短语its superiority, 两者形式不对称。 正确答案,选B.
疑问: 1. 这里C选项不是可以看成 the social usefulness of ... was demonstrated and its superiority... (was) proved. and 连接两句,后句省略be动词吗? 不选C是不是因为superiority 不能与to 搭配?要与over搭配?
2. B选项为什么要用had been? 而不用一般过去时?这里好像看不出and连接的两句有明显先后关系啊...
先谢谢了! |
