I hope the weather there is cold enough
   
其中there是什么成份呢，这不就是一个宾语从句吗？

         could you help me ?  thanks a lot !

这句话的意思是“我希望那里的天气够冷”，这不是宾语从句,there 应该是形容词修饰the weather

经你这么一提示我醒悟过来了，此句应该为宾语从句，there 是个副词

这句话可以改为：I hope the weather is could enough, there .

Do you agree with me ?

"there" here is adverbial

I think your first setence is better than the latter
