Relative to the Moon's age,estimated at around 4.5 billion years,the contraction is recent,occurring less than a billion years ago,and is measured at about 100 metees.中Relative to the Moon's age和estimated at around 4.5 billion years分别是 形容词短语作状语 和 过去分词短语 作状语   与句子主语 是主表关系 
2.The investigation was headed by Thomas Watters of the Center for Earth and

Planetary Studies at the Smithsonian Museum's National Air and Space Museum,Washington.中Earth and Planetary一个是名词作定语,另一个是形容词 作定语 大概 是因为 地球研究 与行星的研究 含义 不一样吧    其实 地球 也是行星  
3.Being online是动词be 的动名词 形式 是动名词 短语 作主语 
 boosts 是谓语
chances是宾语  of being in love是介词短语作定语   being in love是动名词 作 介词宾语（互联网成美国人觅偶重要途径）
4.People who have Internet access at home are more likely to be in a
relationship,with the Web gaining in importance as a meeting place for those
seeking love,according to US research.中Internet是宾语 access是宾补 
逗号后面是with的复合结构 ,with 后面 的宾语 是the Web 后面 gaining 是现在分词作介词宾语的宾补 in importance是现在分词的状语   as a meeting place .是介词短语 作 现在分词的 方式状语

Internet is the one social arena that is unambiguously gaining importance as
a place where couples meet.中of the City University of New York是介词短语 作定语 修饰 Rosenfeld and Reuben Thomas.
as是介词 a place是介词宾语where couples meet是定语从句 修饰 a place 
6.第四句中用的是gain in importance,gain 是不及物动词
而第5句中用的是gain importance,gain 是及物动词
两个gain  前者 意思是  增长 后者意思 是成为 

1. 前面的是一个状语，后面的是个独立主格

2. earth是和前面一起的；planetary和studies是一起的

   还有啊，对于组织机构名称是什么的不用刻意去分析的

3. 第一个being是现在进行的语态，当今。。。；后面的be是表示状态的，前面是of所以用being
