responsible for与be responsible for

问题描述:

responsible for与be responsible for
Someone responsible for economic relations shall be in charge of the administration of economy.
请问在someone 与 responsible for之间是否省略了that?
如果省略了,难道把be也省略了?
不是应该是someone that is responsible

responsible for economic relations 是Someone的后置定语,可以什么也不加
