问题描述
English is considered of great importance for us.介词短语是否是主语补足语，句子倘若换成主动就是宾补，但consider的宾补形式不是to be adj/n 或直接n/adj 的么？ consider的宾补有介词of的么，还是说它原句不是主语补足语？
Consider yourself lucky you weren't in the car at the time.
另外这个句子成分的问题是查词的时候发现的，后半句you weren't in the car at the time.是什么从句
谢谢老师们的回答！
老师答疑
刘老师：
曹老师的解答很好。为了更全面了解 “of + 抽象名词” 的这一用法和现象，我再充实一些内容：
在本句中，of 表示“事物具有某种品质或特性”，of 之后表示此类意义的名词，一般是抽象意义。例如：quality（质量）, use（用途）, importance（重要性）,necessity （必要性）， significance（意义）, beauty（美丽），value（价值），等等。
该结构主要有3种用法：
（1）在名词后作定语；
（2）在be后作表语；
（3）在宾语后作宾语补足语。
（1）在名词后作定语：
【注】此结构可用同源形容词替代，放在名词之前。如：
（2）在be 后作表语：
【注】在此结构中，be of可以理解为have。上述句子可用have取而代之：
也可用同源形容词代替，作表语。例句略。
（3）在宾语后作补足语：
They all consider it of great importance to our work. 他们都认为这对我们的工作很重要。
▲ 你的句子是被动式：English is considered of great importance for us.
of great importance 由原来的宾补变成了主补。
【注】此结构可用同源形容词替代，放在宾语之后。如：
They all consider it very important to our work. 他们都认为这对我们的工作很重要。
▲ 关于这个句子：Consider yourself lucky you weren't in the car at the time.
1. lucky 作宾补。
2. you weren't in the car at the time， 是lucky 的原因状语。
可以把它理解为以下的几种变式：
You were lucky you weren't in the car at the time.
You were lucky that you weren't in the car at the time.
You were lucky because you weren't in the car at the time.
曹老师：
It is very important=It is of great importance.
It is very useful.=It is of great use.
It is useless.= It is of no use.
He is an important man.=He is a man of importance.
一个形容词可以转换为of + 修饰语+该形容词同义的抽象名词。
因此，English is considered of great importance for us.等于English is considered very important for us.
of great importance for us相当于一个形容词。主动句中是宾补，被动句中为主补。
没注意到还有一个问题：
you weren't in the car at the time前面省略了that。这是that引导的原因状语从句。这种that从句和表语形容词后的that从句是一样的。如：
You were lucky that you weren't in the car at the time. that可省略。
I am glad you are here with me.

同意曹老师解答观点
English is considered of great importance for us.
=English is considered very important for us.
=People consider English very important for us.
=People consider English of great importance for us.
be of (great) importance= be (very) important
关于主语+be+of结构
be+of+名词=be +该名词同根形容词 用法
的几种用法
【1】be+of+抽象名词，相当于be+该抽象名词的形容词形成，主要用来表示主语的性质
Sports and games are of great importance.
=Sports and games are very important
体育运动非常重要。
What he said at the meeting was of great value.
=What he said at the meeting was very valuable
他在会上讲的话很有价值。

=This medicine is useless

The book is of no value.
=The book is not valuable
这本书没什么价值。
The tool isn’t of any use.
=The tool is useless.
His words are of no use．
这工具没用。
=His words are useless
他说的话没有用。
【备注】这一结构中的抽象名词前可用great, little, no, some, any, not much等修饰，以表示不同的程度，抽象名词常用importance, value, use,help,等。
【2】be+of+名词还可表示主语的类属。

澳大利亚和新西兰属同一洲。
The two sisters are of the same class.
姐妹俩在同一班。
