be suspended from 从……悬挂下来
根据牛津词典,suspend是及物动词,只有suspend sth from|by sth的用法,物体都是被挂起的
不同于hang,hang是不及物动词,因此一般只用主动。
望采纳!

您好,您提到的是来至于新概念英语第三册的一篇课文。
After switching on powerful arc lights, they saw great stalagmites - some of them over forty feet high - rising up like tree-trunks to meet the stalactites suspended from the roof.
这个句子的主干是 they saw great stalagmites.
主语 = they
谓语 = saw
宾语 = stalagmites
句子用了两个连字符,因为 some of them over forty feet high 和 rising up like tree-trunks to meet the stalactites suspended from the roof 都是宾语补足语,提供更多信息关于 stalagmites(第一个补充说明 stalagmites 的高度,第二个补充说明 stalagmites 的形态)
所以句子错开来就是:
1)They saw great stalagmites, some of them over forty feet high.
2)They saw great stalagmites rising up like tree-trunks to meet the stalactites suspended from the roof.
由于两个宾补都是修饰 stalagmites,句中用了连字符了。
1)They saw great stalagmites, (with) some of them over forty feet high.
这里的介词with省略了,所以可以看做是(介词短语)作stalagmites的宾补,补充说明stalagmites的高度;
2)They saw great stalagmites (rising up like tree-trunks to meet the stalactites suspended from the roof.)
这里是现在分词短语 rising ... 作 stalagmites 的宾补,补充说明 stalagmites 的形态;其中 to meet .... 为(动词不定式)作(目的状语),也就是 rising up like tree-trunks 的目的,就好像是为了和从洞顶垂吊的 stalactites 连接在一起而像树一样的向上生长,而 suspended from the roof 为过去分词短语作 stalactites 的后置定语。
所以第二句的层次是:
1)第一层次:They saw great stalagmites.
2)第二层次:They saw great stalagmites (rising up like tree-trunks).
3)第三层次:They saw great stalagmites rising up like tree-trunks (to meet the stalactites).
4)第四层次:They saw great stalagmites rising up like tree-trunks to meet the stalactites (suspended from the roof).
这里之所有用 suspended 而不是 suspending 是因为 stalactites 尽管不是人为的被吊在洞穴的洞顶上,但钟乳石的产生却是因为水中涵盖了丰富的钙盐,是连续不断的钙盐从洞顶沿着钟乳石一滴一滴的往下滴,滴到地面就是石笋 stalagmites,而留在洞顶的就是 stalactites,经过很长的一段时间,钟乳石和石笋会连接到一起成为石柱了。所以钟乳石是被动地被钙盐覆盖而向下垂吊,而 rising 用了现在分词形式的主要原因在 see ... doing 的结构,还有修饰的 like a tree-trunk 也就是把没有生命的石笋比喻成有生命的树干一直往上成长的主动形式了。

They saw great stalagmites — some of them over forty feet high — rising up like tree-trunks to meet the stalactites suspended from the roof.
They saw great stalagmites rising up是主干,like tree-trunks to meet the stalactites这个是修饰前面的rising up的,suspended from the roof这个是修饰the stalactites的,整个句子用的结构是 saw sb doing sth 过去看见某人正在做某事。这里不是形容词,是被动语法,所以用suspended

被动suspended 是一种过去分词的表达方法。用作修饰。
