to live in 的用法
Zoos are terrible places for animals to live.I've visited a lot of zoos in my life,and I have never seen one I liked or one that was suitable for animals to live in.两句中,为什么第二句话live 加in?
答
·
是做其前面部分的定语.
规律是动词或动词短语与所修饰词构成动宾关系；
如space to live in,space可以做live in 的宾语,即live in space
而不可以说space to live,因为live是不及物动词,后不可跟宾语,无法于space构成动宾关系,必须加个介词（如in）才行.
