There has something been done to help underprivileged in Hon

不对.错处有4：
1,没有用现在完成时态.句子有时间状语last / past /recent years,要用现在完成时态；2,underprivlieged 前面没有用定冠词the.the underprivileged 是指一类人,定冠词不能丢；3,last few yeas 前少了介词in或者over.4,用错了there be 句型.there be 句型的be是固定的,不能改为has或者have,但要注意,there has / have been.是它的完成时态,且 has/have 与 been之间不能分开.
原句改为：There has been something done to help the underprivlieged in HongKong in/over the last few years.是正确表达.
