您好!这是个倒装结构。正语序为:Holograghic technology to present…is using in what is believed to be… 而且,what is believed to be 是插入成分,意思是所认为的,可以括起来就好理解了。 谢谢!希望能帮到你!

1、In what is believed to be a first 做状语 what引导的句子做宾语从句 2、加不加逗号都可以 3、London’s Imperial College Business School主语 is using 谓语 holographic technology宾语 to present lectures to students目的状语
