分析一下句子成分和主干,主谓宾,定状补,急

Advanced technology is being transferred ever more speedily across borders,这是个现在进行时的被动语态。主干就是：sth is being done。即technology is being transferred ,其中ever more speedily 是程度副词性质的修饰,across borders介宾结构。productivity and wages in developing countries will remain lower than in developed countries for many years because developed countries have better infrastructure and better-educated workers。这句主干是 A will remain lower than B。这里A是productivity and wages,in developing countries 是修饰A的,意思是发展中国家的生产力和薪水,in developed countries 原意是修饰B的,在这里充当B吧,表示发达国家的生产力和薪水。所以整个主干句子中,productivity and wages in developing countries 是主语,remain lower是一个系表结构,充当谓语。developed countries 做宾语。for many years 介词短语做时间状语。because后面的充当原因状语从句,解释上述现象的原因。在整个原因状语从句中,developed countries 主语,have 谓语,better infrastructure and better-educated workers。宾语
