求帮忙分析个英语句子，在线等挺急的

Though it had promise, in the end the project failed for three main reasons: the cost of building the enormous machine; the complexity of working with wood; and Hughes’s perfectionist approach, which caused the entire project to finish behind schedule.
帮忙分析下这两句话各自的成分、主谓宾语等!十分感谢!

Answer 1

Though it had promise，作状语the project是主语，failed是谓语，reasons是宾语，冒号后面的都是reason的同位语。
