讨论一道语法题

fanfanzozoUID: 2114008

21.( While) models of automobiles (date back )as far as the late 1600’s, the 1880’s( seen) the first commercial( interest) in the vehicle.


答案：C
分析：这是一个由while连接的两个并列句，逗号后面为一个完整的句子，动词see的对象显然为the first commercial interest，而且它位于see的后面，所以see不应该使用被动语态。根据题意，应该使用see的过去式saw。
改正：seen → saw
翻译参考：尽管第一个汽车模型可以追溯到17世纪，然而是19世纪才看到汽车工业最初的经济效益。
那saw的主语是什么the 1880's

Such use is quite common in the daily English, Let me give you some clues:
The 1880's pushed the post-WWW2 revolution.
It is the 1880‘s that pushed the post-WWW2 revolution.
The X-generation in 1880 pushed the post-WWW2 revolution.
The X-generation in 1880 who be lost  in the overdose and alchole depending pushed the post-WWW2 revolution.
