Help me to solve this problem
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*”,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.
