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
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。

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？
