He has gone to Beijing.
He has been to Beijing.
I have studied English for three years.
He has worked since two years ago.
I haven't had dinner yet.

been就是过去分词
have/has +一般动词变成done，而be动词变成been

He has died.
这里用完成时仅仅表示他刚刚过世，已经死了。
但是不可以He has died for 3 years. 因为不能3年内反复死。

第4句加be动词是因为dead是形容词，
He is dead. --> He has been dead. 他已经死了3年
（dead是一种状态，状态是可以延续的，反义词是alive）
而is 的过去分词就是been 相当于die变成died, do 变成done

have/has +been 现在完成时中表状态。2）的意思是他已经结过婚了，表结了婚的状态（be married).
4)同理，直翻的话，意思是他从三年前开始一直是死的的状态（他已经死了三年了）
