英语句子成分划分疑问

Four score and seven years ago our fathers brought forth on this continent,a new nation,concieved in liberty,and dedicated to the proposition that all men are created equal.
Now we are engaged in a great civl war,testing whether that nation or any nation so conceived and so dedicated,can long endure.
请问这两句的句子成分怎么划分？主谓宾定状补各是哪部分？还有就是能讲解下英语中逗号的用法和逗号在长句的分析中有什么技巧吗？

Answer 1

一楼的同学不要误导人！我们上课时好像讲过这个，是关于美国历史的一篇文章。
第一句：
Four score and seven years ago 时间状语
our fathers 主语
brought forth 谓语
on this continent 地点状语
a new nation 同位语（修饰this continent ）也可理解为brought forth 的宾语。
concieved in liberty 插入语
and 并列连词
dedicated to 与brought forth 并列的谓语
the proposition 宾语
that all men are created equal 同位语从句（解释the proposition） 。
第二句：
Now 时间状语
we主语
are engaged in 谓语
a great civl war宾语
testing 非谓语动词做伴随状语
whether that nation or any nation so conceived and so dedicated,can long endure. 这里可以理解为testing 逻辑上的宾语。
这是我分析希望对你有所帮组！
至于你的第二个问题，我觉得逗号一般放在句首或句中插入成分如状语或定语等。。ANY WAY GOOD LUCK MY FRIEND!
