一个英语的长句...请帮忙分析..Some of the concerns surrounding Turkey's application to join the European Union,to be voted on by the EU's Council of ministers on Dec 17th,are economic——in particular,the country's relative poverty.请各位高手帮我拆开分析这段话的各个成分好么?意思我能看懂...但是我在语法上...指代上不是特别清楚...含糊...请您给做个分析...还有一个点不太明白：to be voted on。请您在语法方面帮我详细分析一下好么？

Some of the concerns surrounding Turkey's application to join the European Union, (插入语to be voted on by the EU's Council of ministers on Dec 17th,） are economic——in particular, the country's relative poverty.
主干：the concerns are economic, particularly poverty.

(主语的定语some of) (the concerns主语）
(surrounding...., to be ...宾语的定语)
(are谓语）
(economic宾语)
(in particular.....宾语的补足语，进一步说明宾语)

Some of the concerns / surrounding Turkey's application to join the European Union,(主语补足语)/ to be voted on by the EU's Council of ministers on Dec 17th,（定语,修饰some of the concerns） / are economic——(整句的谓语部分)/ in particular,the country's relative poverty （补语,补充说明economic）.
主干：Some of the concerns are economic.
