这两个男孩同龄。
二、“be of + 物质名词”,表示主语是由某种材料制成或由某种成分构成,相当于 be made of,be built of,be made up of 等。例如:
The necklace is (made) of glass.
这条项链是由玻璃制成的。
Our class is (made up) of over 50 students.
我们班有 50 多个学生。
三、 be of 还可以表示所属关系,相当于 belong to .例如:

五、“be of+ 抽象名词( value, importance, use, help, interest 等)”相当于“be + 该抽象名词相对应的形容词”。其中 of 表示“具备;具有”, of 不可以省略。例如:

他们对英语学习者来说是很有帮助的。
The press conference seems of great importance / very important.

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 对大学生来说,掌握一门外语是很重要的。
二、“be of+集合名词或其它类型的名词”,相当于belong to或have。of表示归属关系或“有”的意思。如:The army and the people are of one family.

=Mr Wang is one of the best teachers in our school.
王老师是我们学校里最好的老师之一。
worth、worthy、worthwhile的用法区别
这三个词都是形容词,都有“值得的”的意思,但用法或搭配关系不同。
1. worth是一个只能作表语的形容词,意思为“值……的”、“相当于……的价值的”、“有……价值的”、“值得……的”。后接名词、接动名词的主动形式。例如:

The exhibition is worth a visit/visiting.
It’s not worth getting angry with him.
The question is not worth discussing again and again.
2. worthy可作表语,也可作定语。作定语时意思为“有价值的”、“值得尊敬的”、“应受到赏识的”;用作表语时意思为“值得……的”、“应得到……的”,其后接of sth.,也可以后接to do sth.,例如:
①That is worthy of note. 那件事值得注意。
②This phenomenon is worthy of being studied. 这种现象值得研究。

②This is behavior worthy of praise. 这是值得称赞的行为。
③ Something find and rare --- something worthy of the honor of being owned by Jim.

The second-hand house is worthy of being bought. = The second-hand house is worth buyi
⑩There is nothing worthy of mention. 没有值得一提的事情。
