1、They are all groaning about soaring health budgets , the fastest-growing companent of which are pharmaceutical costs.
问题1: 请教曹老师,the fastest-growing companent of which是非限制性定语从句的主语,component是单数形式,为啥定语从句的谓语动词用了are而不是is呢?
2、He was worried sick about his missing son.
问题2: 这个sick在这里只能是一个形容词,worried也是一个形容词,但worried作表语,那么sick和后面的about介词短语是作什么成分呢?
3、The report is being heralded as a blueprint for the future of transport.
问题3: 这里的being heralded是一个动名词词组吗?如果是一个动名词词组,可否改成Being heralded as a blueprint for the future of transport is the report.?
恳请老师的解答,非常感谢!
1 定语从句采用了倒装结构,从句的主语是pharmaceutical costs.
2 动词worry的用法之一为worry sb/oneself+形容词+about sb/sth. 即worry可以后接复合宾语,形容词作宾补,about介词短语作状语。词典例句: He's worried himself sick about his daughter. 这个句子是主动语态,形容词sick为宾补。如果句子改为被动语态,sick就改称为主补。你的句子就是这种用法的被动句。这是被动语态,不是系表结构,sick是主语补足语。
3 这个句子是现在进行时被动语态,不是动名词短语作表语。语义分析就可以排除动名词。不能只看形式不顾语义逻辑。
