GWD17-Q19:

Regardless of their form or function, all aerodynamically enhanced, curved objects made for throwing have been called boomerangs by non-Australians even since 1788, when Europeans saw Dharug-speaking men tossing “bumariny” in the area later known as Sydney.

1. Regardless of their form or function, all aerodynamically enhanced, curved objects made for throwing have been called boomerangs by non-Australians ever since 1788,

2. Regardless of their form or function, any aerodynamically enhanced, curved object made for throwing has been called a boomerang by non-Australians ever since 1788,

3. Ever since 1788, non-Australians have called all aerodynamically enhanced, curved objects made for throwing boomerangs, regardless of their form or function, from

4. Ever since 1788, any aerodynamically enhanced, curved object made for throwing has been called a boomerang by non-Australians, regardless of its form or function, from

5. Non-Australians have called all aerodynamically enhanced, curved objects made for throwing boomerangs ever since 1788, regardless of their form or function, from

请问A为什么不对，longman里有一句例句，All our proposals were rejected, regardless of their merits.

另外请问C，E有什么区别，在大全259里说，after when is unidiomatic，请问from when为什么可以？

这题的答案给的是E

鄙人看法如下：

怎么觉得from when不太对呢

介词是不能跟when连用的 就好比OG里面的after when一样 when=in which那么就是说when已经包含了介词的意思 那么再加上介词岂不是？

单复数对应一致 那么就剩下A了

我觉的应该选A吧, when 是关系副词，怎么能放在介词后作宾语从句的引导词呢？

这提应该选A吧...

E觉得不对我有4个理由

1.from when用法错

2.即使from when正确(这是不可能滴),when与其先行词1788中间插入regardless词组导致句意尴尬

3.call sth1 sth2中因为sth1的修饰语太多导致call与sth2离得太远,不如用被动语态结构清楚

4.原句的重心是具备某些特点的objects早在1788年就被称为boomerangs,而E强调的是Non-Australians怎样怎样

所以还是A正确

A

我到是觉得A不好，主语前的修饰词太多，被动不如主动好，regardless of 在一般后面不在前面

不过E的from的确没道理
