of 在句子裡的結構疑惑
His expertise in jet propulsion will be of great help to us.
可以分析依下這句的句子結構嗎?
特別是針對 of !
我知道of有 ->"的" ，跟 it is kind of you 類似這類的用法
那這邊呢 ?
為什麼雜誌上不用 a 就好了?
His expertise in jet propulsion will be A great help to us.
這樣錯嗎!

His expertise in jet propulsion will be of great help to us.
= His expertise in jet propulsion will be greatly helpful to us.
說明：
1.of + N = adj.這樣的語法通常用在文學上，口語上很少用，比如：
It’s important. = It’s of importance.
2.語氣上再強一點就變成：of great help (of + adj. + N) = greatly helpful (adv. +adj.)
3.中譯：他所專精之噴氣推進技能(知識)，對我們非常(相當)有幫助。
4.這種語法結構與it is kind of you.是不相干的。

To me the two sentences are essentially the same, with slightly different meaning. "His expertise will be OF great help to us" is more general; while "his expertise will be A great help to us" is more specific, as if the speaker has some particular expertise in mind.
