Question

请大家帮我分析这个句子，第1、2个that都是引导的什么句呀，他们在里面起什么作用呀？ act 是什么意思？

The Swedes were the first to recognize that public officials like civil servants, police officers, health inspectors or tax-collectors can make mistakes or act over-zealously in the belief that they are serving the public.

Answer 1

第一个that引导的是宾语从句，做recognize的宾语
第二个that引导的是同位语从句，做belief的同位语，也就是表明belief的内容
act是扮演，表现等的意思

Answer 2

第一个that引导的是recognize的宾语从句，而第二个是belief的同位语从句
act的意思应该是表现，举止等
