[tr][td=369]Although a surge in retail sales have raised hopes that there is a recovery finally under way, many economists say thatwithout a large amount of spending the recovery might not last.

(A) have raised hopes that there is a recovery finally
(B) raised hopes for there being a recovery finally
(C) had raised hopes for a recovery finally being
(D) has raised hopes that a recovery is finally
(E) raised hopes for a recovery finally
[/td][/tr]答案是选D。 请问B ，E  中raised的时态对吗？ 答案解释中没有说到BE中的时态有问题。不知道这里是否必须用现在完成时。

imo,actually. present perfect means continous actions here..the surge still can raise hopes that whatever... now. Do need to change the tense.

嗯，我觉得要留完成时。因为主句是economists say...所以从句最好找一个时态能和现在挂上钩的。完成时比一般过去时在这个作用上肯定要好。

O(∩_∩)O谢谢！那么这道题是不是一定不能用raised？ 还是仅仅是 has raised比raised好，只是一个有效性的问题？为什么？
