请高手帮忙分析一下句子成分

原句是：It is considered a museum of the East meeting the West and the past Joining the present. 中间的分词做什么成分啊 谢谢 然后 the East meeting the West 整个短语是什么结构 ？ 谢谢
答：consider sb./sth. (to be) sth. consider后跟复合宾语，宾补为名词。意为“认为。。。 是。。。”
如： We consider him an honest man. 我们认为他是一个诚实的人。
被动：He is considered an honest man.
此句主干就是：It is considered a museum of + 二个动名词复合结构： the East meeting the West and the past Joining the present.
这个结构简化了就是：A's meeting B and C's joining D
注：动名词的逻辑主语如果是人，常用名词所有格。如果是事物，常用名词普通格，如本句。
翻译：这被认为是一个中西结合，古今交融的博物馆。

定语从句修饰a mesuem,结构是主谓宾，the East 是主语，meeting是谓语 ，the Weat 是宾语

meeting：gerund, object of the preposition of
Joining：gerund, also object of the preposition of
when gerund acts as the object or subject it can have the subject or object of its own.
understand me?
the East meeting the West：gerund phrase,主语谓语宾语结构，the East，the West分别是动名词meeting的逻辑主语和逻辑宾语。
understand me? ?

It is considered: it是主语，is considered被动语态的谓语。
a museum of the East meeting the West and the past Joining the present是主语补语，它的中心词是 museum.
如果把这个句子还原成主动句你就看滴更清楚了：We considered it a museum of the East meeting the West and the past Joining the present. 这里we是主语，considered 是谓语，it 是宾语，museum 成了宾语补语了。呵呵。
understand me???
