英语语法选择There are four factories in our institute,-------A.wit

1.答案：B.
2.翻译：在我们学院有四家工厂,每家都有一百多工人.
3.
1）A with each has over 100 workers
A使用“with + 宾语 + 宾语补足语”结构,要求做宾语补足语的动词用非谓语形式,而A中的has为动词的三单形式,它是谓语形式,排除；
2）C.which there are over 100 workers
C中使用非限制性定语从句,但是关系词该用where=in which=in four factories.用which时不能在定语从句中充当地点状语的,排除；
3）D.with having over 100 workers
根本就不通,
4）B.each having over 100 workers
B采用独立主格结构,each指each factory,它和have之间是主动关系,所以用现在分词having.
