of 加抽象名词啥意思
be+of+抽象名词是什么意思 举例解释加说明

Answer 1

"(be)+of+名词"结构中的名词是抽象名词时,相当于其中名词所对应的形容词的意思,说明被修饰词具有某种特征或属性.
常用的名词有use/importance/help/value/interest/quality/service/benefit/necessity等.
例如:I don't want to hear what you are saying.It is of no interest to me.
我不想听你说,我对此不感兴趣.(of no interest=not interesting)
Doing morning exercises will be of benefit to your health.
做早操对你的健康有利.(of benefit = beneficial)
Coal is of great importance to the development of industry.
煤对工业发展是相当重要的.(of great importance=very important)
