"I am of those who like to stay late at the cafe," the older waiter said.
"With all those who do not want to go to bed.With all those who need a light for the night."
"我是属于那种喜欢在餐馆呆得很晚的人,"那个年纪大些的侍者说."我同情那种不想睡觉的人,同情那种夜里要有亮光的人."
"I want to go home and into bed."
"我要回家睡觉去了."
"We are of two different kinds,"
答：语法是：介词短语可以作表语.
具体一点：of +抽象名词=对应的形容词 作表语如：
Sth.is of great help/ use/ importance.= Sth.is very helpful/useful/important.
XX是很有帮助的/很有用的/很重要的.
本例尽管和我说的这个不完全一样,但属于of+名词作表语.表示：是.的.
最后那句话也是这种结构：
"We are of two different kinds,"
