请问were和special中间那个of的意思、用法以及所根据的语法规则
Epidemics were of special concern due to the high population density and tropical climate of the affected areas

“be of+抽象名词”,这时的of短语相当于这个名词的同根形容词,作为表语表示主语的性质或特征.
此处意为;Epidemics were very much concerned...
类似用法,如:The matter is of great importance.=The matter is very important.
