关于in demand
词汇书上的例句:Programme experts are in great demand in the information age.这里的in demand 后面需不需要介词of,for...
如果是in need怎么样?
我想不通的是不是说说we are in need of experts.那改成被动语态的时候,不是应该有介词吗experts are in need of?就像they are taken good care of

个人认为,被动语态应该有及物动词啊,可we are in need of experts不符合被动语态条件,所以不要混淆.楼上说得对,demand就是个名词
