分析一下复合长句

问题描述:

分析一下复合长句
The first thing i believe we absolutely must do is to reduce the amount we use our cars
The first thing 主语
i believe 省略that的定语从句
那么 we absolutely must do 是什么成分?
is to reduce the amount we use our cars 又做什么成分?

句子翻译:我确信我们必须做的首要的事情就是减少我们的用车量.这个句子主句是一个主系表结构的句子.The first thing i believe we absolutely must do是主语is是系动词to reduce the amount we use our cars是表语...那定语从句中 怎么会有believe和 must do 两个 谓语呢?I believe we absolutely must do是个宾语从句,I主语,believe谓语动词,we absolutely must do是个宾语从句。也就是说,这句话是主系表结构,主语是个定语从句,定语从句中又包含了宾语从句。是的,英语就是这么恶心。
