请问老师,上面两个句子为什么有介词of,这表达了怎样的逻辑关系?谢谢回答。
be of +名词=be+该名词的"同根形容词"
(be of +importance=be+important)

类似下面句子

=He is middle-aged.

of的这个用法是它最基本的用法。即表示“具有...属性的”,英英词典解释形容词的意义时,多用of结构来解释。如economic:=of economy. 翻译成汉语,of的这种用法就相当于“。。。的”。of + 抽象名词=相同意义的形容词。of great importance=important, of some use=useful, of no use=useless.
另外,of + great importance=very important 二者虽然意义相同,但语体不同。前者显得更正式,具有文绉绉的味道,适合于正式书面语。日常英语相对用得少。因此这种用法也不能滥用。
