Question

There is no doubt but he won.
but he won 是定语还是同位语?
2,It's not so high but we can jump it.
它的同义句是什么?

Answer 1

1.There is no doubt but he won.
此句中的but为介词,引导一个省略了that引导的宾语从句.
即 = There is no doubt but that he won.
毫无疑问他赢了.
当然,也有的语法书上直接把but等同于that,这样它就引导doubt的同位语从句了.
2.It's not so high but we can jump it.
= It's not so high that we can't jump it.
but = that...not...
它并没有高到我们爬不上去.
发现楼主有死钻语法的倾向了,
这些用法都太难了,平常考试几乎不可能会考得这么偏门的.
