There is not just one big public whose opinion a company has to worry about if it is to survive
问题描述：
There is not just one big public whose opinion a company has to worry about if it is to survive
在这个句子中there is not just one big public whose opinion 做什么成份
是宾语从句还是表语从句？
答
句型分析：
主句：There is not just one big public （不仅仅只有一个大众）
宾语从句：whose opinion a company has to worry about if it is to survive（公司为了生存,它必须担心大众的观点,whose 引导宾语从句,修饰big public）
全句翻译：（对于公司来说,）公司为了生存,它必须担心不仅仅是某一个大众的观点.
开始说错了,抱歉!
这儿,既不是宾语从句,也不是表语从句,只是一个普通的定语从句：one big public 作 先行词,后面的whose引导从句.
宾语从句,在整个句子中作宾语,这儿There is not just one big public 是一个完整的句子；
同理,表语从句,在整句中作表语,一般和系动词一起修饰主语,这儿主句是完整的,不缺表语.
