标题: 大全651, 关于since的使用问题;
Since the 1930’s aircraft manufacturers have tried to build airplanes with frictionless wings, shaped so smoothly and perfectly that the air passing over them would not become turbulent.
(A) wings, shaped so smoothly and perfectly
(B) wings, wings so smooth and so perfectly shaped
(C) wings that are shaped so smooth and perfect
(D) wings, shaped in such a smooth and perfect manner
(E) wings, wings having been shaped smoothly and perfectly so

OA:B了   我选了A; 很多同学说A错,是因为 shaped这个动词有歧义; 可以是  Wind shaped  也可以是  airplance shaped;

这时候。。。横空杀出来一位高手;说了一句很有道理的话:  since引导的是一个从句; 如果选A 则主句没有主语;我觉得这个解释好有道理;

但是再看一下题,我产生了一个疑问:
Since 到底是引导了一个从句?  Since bla bla bla。。。wings,  还是Since 只是 Since the 1930‘s  这样的一个用法呢?  这里没有逗号,不晓得是不是typo;

感谢各位;

的确是since引导的时间状语从句

同意楼上,的确ACD少了主语,fregament了

since引导的只是时间状语啊

Since the 1930’s/ aircraft manufacturers have tried to build airplanes with frictionless wings

后面的shape如果不写明是修饰先行词,就会有airplanes shaped和wings shaped的歧义,还可能是manufacturers shaped,因此排除A/D
E的having been shaped错,排除E
C的shaped so smooth错误,该用smoothly和perfectly
另外,如果把shaped smoothly and perfectly放在一起的话,perfectly中就包含了smoothly,所以也有一点重复的感觉
