请教大全 985 959

Those who have visited the Grand Canyon have typically seen layers of sediment in the gaping canyon, with different colors that mark the passage of time like the rings in a tree trunk.

(A) seen layers of sediment in the gaping canyon, with different colors that mark

(B) see layers of sediment in the gaping canyon, whose different colors mark

(C) been seeing layers of sediment in the gaping canyon, whose different colors are markers of

(D) been able to see layers of sediment in the gaping canyon, with different colors marking

(E) seen layers of sediment in the gaping canyon, marking by different colors

答案是D,记得看过一条语法规则with sth doing 永远不被GMAT认可，我觉得A也可以，尽管意思表述模糊了些

Child care already a solid part of the employee benefits package at many companies, more businesses are focusing on a newer family benefit known as elder care, servicing for older dependents.

(A) Child care

(B) With child care

(C) Child care as

(D) Being the Child care was

(E) With child care’s being

答案是B，A作为独立结构错在哪里呢？

抱歉！以前只按照大全的题号来查，没有查到这两题。

第二题虽然with有“原因”的概念，但我还是觉得过于口语化，A还是显得比较“文气”，请问在考场上应该如何判断？这种感觉依赖不得吧！

985－前人的讨论，结果是A，参见http://forum.chasedream.com/dispbbs.asp?boardID=23&ID=27844

顺便我再指出前人关于with独立主格是否合理的个人看法：我认为with + n. + like(介词短语)完全是可行的独立主格形式，而且，从句意上这种结构更合理，我支持A。
