Architects and stonemasons, huge palace and temple clusters were built by the Maya without benefit of the wheel or animal transport.

(A) huge palace and temple clusters were built by the Maya without benefit of the wheel or animal transport

(B) without the benefits of animal transport or the wheel, huge palace and temple clusters were built by the Maya

(C) the Maya built huge palace and temple clusters without the benefit of animal transport or the wheel

(D) there were built, without the benefit of the wheel or animal transport, huge palace and temple clusters by the Maya（C）

(E) were the Maya who, without the benefit of the wheel or animal transport, built huge palace and temple clusters

A, B, and D illogically suggest that the palace and temple clusters were architects and stonemasons. For the modification to be logical, Architects and stonemasons must immediately precede the Maya, the noun phrase it is meant to modify. A, B, and D also use the passive verb form were built, which produces unnecessary awkwardness and wordiness. E is awkwardly phrased and produces a sentence fragment, because the appositive noun phrase Architects and stonemasons cannot serve as the subject of were the Maya. why?

C, the best answer, places the Maya immediately after its modifier and uses the active verb form built.

推出一个问题：如果A/B是两个集合的话，主系表结构“A is B”是不是意味着：A集合小于等于B集合（即A包含于B）？

如果是同位语结构“A，B is”，则同位语与主语各自的概念范围上可以有差别吗？（因为同位语起解释说明作用）

谢谢rakesun! 先记下了。

请问一下真的有楼上他们所说的某个集合包括另一个集合么？？？？

同位语不就是解释说明么，难道非要用一个更大的集合来说明？
