非谓语动词作状语
1.不定式在句中作状语常表目的、结果或原因;分词作状语表示时间、原因、让步、条件、方式、伴随等。

Being a model Party member,I should work even harder.作为一名模范党员,我应该更努力工作。(表示原因)
Given more time,I could write the composition better.若是再多些时间,我会把文章写得更好。(表示条件)
He ran out of the classroom,shouting at the boy.他跑出教室,冲那男孩大喊。(表示伴随)

He is old enough to join the army.他到了可以参军的年龄。(表示结果)
I am only too pleased to accept your kind invitation.我非常乐意接受你的盛情邀请。(表示结果,only/all too……to do表示“非常”)
2.有些分词短语可以独立存在,在句子中没有逻辑中的主语而实际上已经变成了习惯用法。如generally/strictly speaking"总的/严格来说"、judging from"从……判断"、talking of "谈到"、considering/given"考虑到"、regarding/concerning“关于”、provided/providing/supposing/given"假设"、including"包括"、seeing (that)"既然"等。

Seeing (that) =Since you love her so much ,why don"t you marry her?既然你如此爱她,为什么不娶她呢?
