Question

Only in the last few years has there something been done to help the underprivileged 这个句子对吗？

Answer 1

不对，可以改成：

1. Only in the last few years has something been done to help the underprivileged.
2. Only in the last few years has there been something done to help the underprivileged.

解释：
1. only引导状语置于句首时，该句必须采用部分倒装结构。
所以第一种改法正常句序为：
Something has been done to help the underprivileged (only) in the last few years.
第二种改法正常句序为：
There has been something done to help the underprivileged (only) in the last few years.
2. 其中第一种为被动语态，第二种为there be句型。
因为时间状语in the last few years决定了句子只能采用现在完成时态。

建议采用第一种改法，第二种改法虽然语法无误，但是比较生硬。
