老师几个问题
But there is also time for brief diversions onto bizarre ground,such as a discussion of the skyscraper index (which holds that a boom in skyscraper construction is a foolproof sign of an imminent recession)这里的there is also time for是相当于it is time to 括号里的内容是定语从句套宾语从句吗?which是作主语吗?hold that是不是相当于think that.
Mr.Smith's book serve as an excellent introduction to a vast subject这里是不定式作 introduction
In what way is the year 2008 historic又是什么意思?
introduction那里是作定语还是宾补?it serves as a guide to arts and commerce这里的to do也是宾补吧.I have an important lecture to attend这句为什么是定语不是作状语我都有点混淆了,怎么区分?

Answer 1

But there is also time for brief diversions onto bizarre ground, such as a discussion of the skyscraper index (which holds that a boom in skyscraper construction is a foolproof sign of an imminent recession)这里的there is also time for不是相当于it is time to do
前者是有时间 作某事 后者是该 做某事
括号里的内容是定语从句套宾语从句
which是作主语 hold that不是相当于think that.而是means that 因为 think的主语不成立
Mr.Smith's book serves as an excellent introduction to a vast subject这里没有不定式
to a vast subject是介词短语作定语 修饰 introduction
In what way is the year 2008 historic= the year 2008 historic is in what way
as an excellent introduction 是状语
it serves as a guide to arts and commerce这里的 as a guide to arts and commerce是状语
to arts and commerce是定语 修饰 a guide.
本句没有宾语 所以也没有宾补
