分析一个英语句子结构 Identical twins Katie and Sarah Monahan arrived at Pennsylvania's Gettysburg

Identical twins Katie and Sarah Monahan arrived at Pennsylvania’s Gettysburg College last year determined to strike out on independent paths. 这个句子的主谓宾结构是什么？determined前为何不加and?这个词是非谓语动词吗？还是arrived?

Identical twins Katie and Sarah Monahan 是主语arrived at 是谓语Pennsylvania’s Gettysburg College 是宾语last year是状语 determined to strike out on independent paths可以看作是过去分词短语作状语。determined前不加and因为不是并列谓语，该词可以看作是非谓语动词。如果加and看作谓语动词的话应该是and were determined to strike out on independent paths
本句中作状语的过去分词短语也可以放在句首，即： Determined to strike out on independent paths,identical twins Katie and Sarah Monahan arrived at Pennsylvania’s Gettysburg College last year .

Identical twins Katie and Sarah Monahan （主语）arrived （谓语）at Pennsylvania’s Gettysburg College last year （状语）determined to strike out on independent paths.（分词做伴随状语） determined 在这句中是分词做状语的用法哦~~~

Identical twins， （Katie and Sarah Monahan 同位语）， （arrived at Pennsylvania’s Gettysburg College last year，过去分词短语作状语），（determined 谓语动词）to strike out on independent paths.

你好！ Identical （定语）twins（主语） Katie and Sarah Monahan（主语同位语） arrived （谓语）at Pennsylvania’s Gettysburg College （做介词at的宾语）last year （时间状语）determined（状语） to strike out （词组做to的宾语）on independent paths（词组做on的宾语） He came home，tired. 句子里determined和这里的tired一样用法，做状语，不是定语。 仅代表个人观点，不喜勿喷，谢谢。
