英语翻译
Control engineering is an exciting and a challenging field.By its very nature,control engineering is a multidisciplinary subject,and it has taken its place as a core course in the engineering curriculum.
就翻一下这一句“it has taken its place as a core course in the engineering curriculum.
”
其中第二个it代表什么呀?take place as 是固定用法?
为什么要用被动语态？第一个it指的什么？

Answer 1

控制工程学已经在工程学课程中充当/成为一门主要的课程.
it代表 control engineering; take place asxx 可以说是固定用法,意思是充当xx / 扮演xx角色.
这里面没有涉及到你所谓的被动语态哦,这里的 it has taken 是现在完成时态的标志.
