be of 加名词 这是一个什么用法,表达什么意思? 5
be of 后可接两种不同性质和类型的名词,他们的意义大相径庭。
一、be of 后可接value, importance, use, help, significance, interest, benefit 等一些抽象词,
这样的结构用来说明句子主语所具有的作用、重要性或意义。 在这类抽象名词前我们可用一些形
词,如: great, little, some, any, no, not much等来修饰抽象名词,用以说明程度。如:
1、They are of great help to learners of English.
他们对英语学习者有很大帮助。
2、The book will be of great value to students of history.
这本书对学历史的学生将很有用。
二、be of +名词,还可用来说明句子主语在度量,大小,颜色,类别等方面的特征。这类名词有
colour, age, size, height, weight, shape, type,kind, quality等。在这类名词前常用different,
all, the same, this, that, a(n) + 形容词等词来修饰或说明。如:
1、Coins may be of different sizes, weights, shapes, and of different metals.
货币可能在大小、重量、形状和铸造的金属方面都有所不同。
2、These pens are of many different colours.
这些笔有许多不同的颜色。
扩展资料:
在“be of + 抽象名词”结构中, 其意义就相当于 “be + 与该抽象名词同词根的形容
词”。如:be of value→be valuable, be of help→be helpful, be of use→be useful, be of
importance→be important, be of significance→be significant等。它们之间可以相互转
换, 因此,以上各例句可转换为:
1、They are very helpful to learners of English.
他们对英语学习者有很大帮助。
2、This book is very valuable to students of history.
这本书对学历史的学生将很有用。
He is of that time. 他是那个时代的人。(= He is a man of that time,省略了与he意思重复的同类名词a man)
The story is of adventure. 这是个冒险的故事。(= The story is a story of adventure,省略了与主语重复的名词story)
They are of great help to learners ofEnglish. 它们对英语学习者有很大帮助。(= They are books(或materials) of great help to learners of English,省略了与主语意思重复的books或materials)

of use=useful;of nouse=useless;of importance=important等.如:
The matter is of great importance.=The matter is very important.
在形容词前常用very来修饰,在“of+抽象名词”结构中,名词前常用great, much等来修饰.再如It is of great importance for college students to master a foreign language.
=It is very important...对大学生来说,掌握一门外语是很重要的.
