求分析此英语句子The painting considered to have been copied Should h

The painting/ considered to have been copied/ should have won the prize
见上句的斜杠,the painting是主语,should have won the prize为谓语和宾语,所以主句就是
the painting should have won the prize,那幅画应该得奖.
而中间的部分 considered to have been copied是用来修饰主语the painting的,说这幅画被认为是抄袭的.
合起来就是,那副被认为是抄袭的画应该获奖.
