A 中的more established industries 很容易产生歧义，more 是修饰established 还是 industries呢？B中的 industries that are more established更好。

支持 B。

 A 不可选。A 有几个硬伤：

1、the more established industries，这种表达会造成“more (established industries)" 还是" (more established) industries" 的歧义，具体可以参照 大全-250 more gasoline-efficient cars 那题。

而 B 改成 industries that are more established 则有效避免了歧义。

2、companies that compete 不如 competing company简洁。有形容词可用的情况下为什么要用定语从句？而且我觉得 B 里面的 competing companies one day may be partners the next 形式上很对称。(competing companies |one day) may be (partners | the next ) 不是吗？

3、还是并列与对称的问题，整个句子看 Although 主语 be adj (in bla bla bla...), they be adj (in bla bla bla...), as...  结构很完美啊，相比 A 还破坏了并列平行呢。

我选B,补充一点,我认为lines前面的the也是必须的

"Whereas" and "although" are both correct. We can't choose between A and B on the basis of these words.

The reference of the pronoun "they" is unambiguous in both A and B. It refers both logically and grammatically to the subject of the preceding clause "lines." We can't choose between A and B on the basis of this word either.

What makes B wrong is the phrase: "as competing companies one day may be partners the next." The separation of "competing" from "one day" confuses the intended meaning. In A, "companies that compete one day may be partners the next" is clear and logical.

看了楼主推荐的链接，给出这个解释的人好像是个外国的大牛。说的很有道理。之前我选B，现在改选A。

对A来说，曾经竞争的公司是主语
对B来说，竞争的公司和one day的关系不明确，因为one day作为副词是不能修饰名词的，也就没有了A中的意思。
这是我的理解，盼拍砖。

我觉得如果是b的话，去掉the next 不是更好吗，觉得one day 和the next有重复

以下是引用s7s7在2007-6-17 10:23:00的发言：
as companies that compete one day may be partners the next.



我知道lz意思是that compete做companies的定语从句，



但是，不啰嗦吗，我把这种结构当作错误结构，不论是日常说话，还是书面写作



Lz可能会说：OK，one day就是修饰compete，我认为，非



有朝一日是修饰可能会（成为合作伙伴）而不是compete

我知道这种重复可以做一个语法点
可是B也有同样的问题啊
B:Although the lines of competition are clearly defined in industries that are more established, they are blurred and indistinct in the Internet industry, as competing companies one day may be partners the next.
这里不也是有同样的问题吗？

呵呵  perfect
我不知道ed形式是不是也倾向于表示持久的状态，如果是的话，ing也是表示持久状态，that从句表示一次性动作。那么这个题就可以直接结合逻辑意思找到答案了。
