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!
