请帮我分析这个长句
The country that gave the world Windows and the Internet is in danger of losing its lead in information technology while the importance of IT to the US economy has risen sharply over the past decade—fully a third of its economic growth since 1992 has been in this area – federal funding for IT research has remained flat or declined in real terms.
弄不明白意思的有:flat or declined ,in real terms
弄不明白的句子有：while 这个连词在这里是什么意思?fully a third of its economic growth since 1992 has been in this area 这句话的主、谓、宾是什么?我看不懂.federal funding for IT research has remained flat or declined in real terms.这句话是什么从句呢?为什么用--- 这个符号啊?

flat or declined：持平或者下降,
in real terms：事实上,
while,连词,表示相反来说,反过来,
fully a third of its economic growth since 1992 has been in this area：这不是一个独立的句子,是个词组,做has risen 的状语,说明上升的程度.
federal funding for IT research has remained flat or declined in real terms.这句话不是从句,是一个独立的句子.
--- 这个符号不是为后面服务的,而是为前面fully a third of its economic growth since 1992 has been in this area服务的,为了将它与其他句子分割开来,功能是解释这个部分的意思.但是整句又表达了一个连贯的意思：
为世界提供了视窗和互联网的这个国家现在面临着在信息技术领域里失去领导地位的危险.与此同时,在过去的十年中,信息技术却对美国经济的重要性急剧上升,也就是说,自1992年以来,三分之一的经济增长来自这个领域,而美国国会对信息技术的研究项目却数量持平,实际上有所下降.

这个句子的主语是 The country
that gave the world Windows and the Internet是主语从句，
is in danger of losing its lead in information technology是谓语，下面的就是一个从句，fully a third of its economic growth since 1992 ...
