Question

帮忙分析一下这个句子的结构，主谓宾等。。

From the shore line,out to a distance,which may be anywhere from a few miles to a few hundred miles ,runs the gentle slope of the continental shelf,geologically part of the continents.新概念4的30课一句话，帮忙分析一下。

Answer 1

这是个倒装句。

·主语是the gentle slope of the continental shelf,意思是“平缓的大陆坡”，更确切的说主语应该是 slope of the continental shelf。

geologically part of the continents是形容 slope of the continental shelf的，意思是“地质学上是大陆的一部分”。

·谓语是run.

·这个句子没有宾语，From the shore line,out to a distance是状语。

which may be anywhere from a few miles to a few hundred miles是形容distance的从句，其实就是from shore line out to anywhere from a few miles to a few hundred miles意思是“从海岸线向外延伸几英里到数百英里不等”。

如果把这个句子写回正常语序的话，就是
the gentle slope of the continental shelf，geologically part of the continents，runs from the shore line,out to a distance,which may be anywhere from a few miles to a few hundred miles。

翻译过来就是和缓的大陆坡在地质学上讲是大陆的一部分，其沿着海岸线向外延伸至几英里到几百英里不等。

Answer 2

From the shore line,out to a distance,which may be anywhere from a few miles to a few hundred miles ,runs the gentle slope of the continental shelf,geologically part of the continents.句子本身是全倒装，把介宾短语放句首，可简化为：

From the shore line runs the gentle slope of the continental shelf.大陆架的平缓陡坡从海岸线穿过。

其中省略的out to a distance,which may be anywhere from a few miles to a few hundred miles 、geologically part of the continents都在限定、修饰这句句子主干。

如out to a distance,which may be anywhere from a few miles to a few hundred miles 限定、修饰shore line海岸线（什么样的海岸线？离开一定距离的、可能是从几英里、几百英里以外来的海岸线）；geologically part of the continents限定、修饰continental shelf大陆架。（什么样的大陆架？地质学上说是大陆的一部分的大陆架）
