The Anasazi settlements at Chaco Canyon
were built on a spectacular
scale, with more than 75 carefully engineered structures, of up to 600 rooms each, were connected by a complex regional system of roads.
答案(B)scale, with more than 75 carefully engineered structures, of up to 600 rooms each,OG的解释:
The second part of the sentence,introduced by the preposition with,describes the structures first in terms of their rooms ,and then in terms of the roads that connect them together.To describe the noun structures,the participal form connected should be used,turning the verb into an adjective.
由此可见 with...修饰settlements，connected是修饰structures
the settlements...scale，with...structures，of up to 600 rooms each, connected...
为了好理解 变为 ZJ , A , B , C
问：
1 A B 是否插入语？ 如果connected修饰structures B应该是插入语
2 如果B是插入语 修饰ZJ的词 还是修饰A中的词？
3 如果A是插入语 B难道不应该跳过插入语去修饰ZJ的词吗？
问题有点绕。。。不过困扰死我了。。这个插入语来。。。

参考国外论坛的解释。里面提到，句子主要结构是 the settlements were built with structures, connected...
(see http://www.manhattangmat.com/forums/the-anasazi-settlements-at-chaco-canyon-were-built-t2236.html)
-----------------------------------------------
choice a is a run-on - it tries to have two main verbs without using any sort of subordinating element. if you take out modifiers, adjectives, etc., you're left with the following: the settlements were built with structures were connected. that's bad.
choice b is correct: it uses a nonessential modifier set off by commas ('of up to 600 rooms each'), which, if eliminated, yields the intact and legitimate sentence ...carefully engineered structures, connected by... (with another nonessential modifier).
choice c:
- 'scale of' doesn't make sense
- you can't say 'each that had...' (can't follow 'each' with a relative pronoun - if you're going to use a relative pronoun, it has to come directly after the thing it's trying to modify)
- no justification for using the past perfect ('had been') - that verb, if there's a verb there at all, should be in the simple past (the same tense as everything else in the sentence, because everything described in the sentence is contemporaneous)
- it doesn't make sense to use 'each' AFTER the comma, because it's not true that each structure was connected with a road system. instead, the road system connected all of the structures with each other, which is nowhere close to the same thing. (having 'each' BEFORE the comma makes sense, because it's actually true that each of the structures comprised up to 600 rooms.)
analogy:
the USA comprises 50 states, each of which is united by a federal government --> wrong (the implication is that each state has its own federal government)
the USA comprises 50 states, all of which are united by a federal government --> correct
the USA comprises 50 states, (all) united by a federal government --> correct, whether you have 'all' or not
choice d:
- 'scale of' doesn't make sense
- the use of AND sets up ostensible parallelism, but the two structures given aren't parallel (one starts with of and the other with with)
choice e is also a run-on sentence (you'll see this if you reduce it to its 'skeleton', a la choice a)
