it's reported that the way people spend their holidayhas cha

很简单,因为加了介词以后就是词组,词组作状语,但是这里的【the way】不是状语请看分析：【It's reported that。。】由it这个形式主语引导后面一个that从句,意思是。。。被报道了【the way】是从句中的【主语】【people spend their holiday】是从句主语的【定语】,相当于【the way that people spend。。。】【has changed】从句中的【谓语】,是现在完成时【a great deal】许多,是程度副词【in the past ten year】在过去十年,是时间副词作状语翻译：据报道,过去十年间人们过节假日的方式改变了许多。
