bryony, 这题问得好，我还真不清楚它的语法错误。我只能说一般说一个因素，像陈述一个事实，用现在时比较好吧？虽然它跟了一个可以用现在完成时的时间状语。

大家的意见呢？

UP！

我也这么convince 自己的。不过这个C总让摸不找具体的错误。

比如说这么个句子：

Up to now, there has been no effective treatment for AIDS. --from Longman

这应该也是一个事实呀。感觉自己有点绕进去了。

请继续讨论。

has been experiencing 没有依据啊，不能作为答案

以下是引用tangyi79在2004-3-5 15:16:00的发言：
(C) In the last 50 years, one of the most significant trends that the auto industry has been experiencing has been

has been experiencing 没有依据啊，不能作为答案

可是in the last 50 Years,就是表示完成态的时间呀。

has experienced强调的是从过去的一段时间到现在所经历的事
has been experiencing除了强调从过去到现在外，还强调这个事可能持续到将来
in the last 50 years强调的是从过去到现在的一段时间，没有对未来的一种可能性，所以用has experienced更好一些
另外就像dansy说的一样，这是事实，所以C的第二个has been不是很好
