that the driver was drunk is obvious 句首的that 能否省略?
that 引导主语从句时,好像不能省略,但是
the driver was drunk is obvious 这个句子好像也对
求分析

the driver was drunk is obvious这就不对了,因为the driver变主语了,was 跟 is是两个谓语.
原先是 ”that the driver was drunk“ 这个短语整个是主语,表示driver喝醉了这件事is obvious

不能，这是主语从句，that引导的从句 整个做主语。

不能省掉 其实应该说its obvious that the driver was drunk , 英文里没有 the driver was drunk is obvious这种说法

the driver was drunk is obvious这就不对了，因为the driver变主语了，was 跟 is是两个谓语。
原先是 ”that the driver was drunk“ 这个短语整个是主语，表示driver喝醉了这件事is obvious

that不能省略的，这个句子必须有that做为引导词充当主语成分。希望你能采纳

不能省略
如果省略了句子就成了两个谓语这会使句子在理解上混乱
只有当它引导的是宾语从句才可以省略

其实本句话是对的。因为此处that引导的是一个主语从句：That the driver was drunk；is是系动词，obvious是表语。其中主语从句的引导词此时不能省略。
当然用形式主语it放于句首，把that...从句放到后面也对。即：It is obvious that...。
