Most of these houses are of the same basic form: end-gabled, one-and-one-half story rectangular structures with the main entrance door centrally fixed on the long wall and a chimney at the short end of the house.如何翻译这句话,另外,想请问,第一句,are 后面为什么加一个of, 为何意? one-and-one-half story是什么意思?Thanks so much.

翻译就免了,一楼已经翻译了.下面介绍be of的用法
be of 结构用法很灵活,在句中可作表语、后置定语或宾补.
一、“be of+ 表示年龄（ age ）、大小（ size ）、颜色（ color ）、重量（ weight ）、高度（ height ）、价格（ price ）、意见（ opinion ）、形状（ shape ）、种类（ kind ）和方法（ way ）等的名词”,表示“具有……”,说明主语的特征.例如：
When I was of your age,I entered the war.
当我是你这个年龄的时候,我就去打仗了.
These flowers are of different colors.
这些花的颜色都不同.
注意：在此结构中,如果后面的名词前有不定冠词 a / an ,则这个冠词相当于 the same .例如：
The two boys are of an / the same age.
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：
China and India are of the third world.
中国与印度同属于第三世界.
Workers and peasants are of one family.
工人和农民是一家.
四、“be of + 形容词最高级”,相当于 be one of… .例如：
His temper is of the quickest.
他的脾气是最急躁的.
Mr Liu is of the best teachers in our school.
刘老师是我们学校最好的老师之一.
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：
They are of great help / very helpful to learners of English.
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.
这个新闻发布会看来很重要.
