1. GWD28-Q1:

Scientists claim that the discovery of the first authenticated mammal bones in amber could provide important clues of determining, in addition to how, when mammals colonized the islands of the West Indies.

A.      of determining, in addition to how, when mammals colonized the islands of the West Indies

B.       in the determination of how and when the islands of the West Indies were colonized by mammals

C.      to determine how mammals colonized the islands of the West Indies and when they did

D.      for determining when the islands of the West Indies were colonized by mammals and how they were

E.       for determining how and when mammals colonized the islands of the West Indies

请问同正确答案E比较，C错在哪里？

A.      with the Congressional Medal of Honor, which was the nation’s highest military award, and which was long overdue in

B.       with the Congressional Medal of Honor, the nation’s highest military award for long-overdue

C.      the Congressional Medal of Honor, which was the nation’s highest military award, long-overdue in

D.      the Congressional Medal of Honor, the nation’s highest military award for long-overdue

E.       the Congressional Medal of Honor, the nation’s highest military award, in long-overdue

请问正确答案e中，award ... in long-overdue recognition 是什么用法 

谢谢！

28-1题答案C的to do有问题.

先说说provide这个词,提供.按照逻辑的合理性,应该是provide sth for sb to do, 或者, provide sth against sth. 而C中to do不定式表示目的, 但因为provide的发出者作为to do的逻辑主语会不合逻辑, 所以to do的逻辑主语缺失;

根据前人搜集的资料,provide important clues to的用法也是有的.不过to是作为介词使用,也就是to doing XX.所以C答案在to determine这个部分使用有误.

再者,那个how...and when they...的组合比how and when...要来得啰嗦.

至于29-1,在原句中有一个细节需要注意, 那就是nation's highest military award和long overdue in recognition of...是平行的,都为congressional medal of honor的修饰语.

能够满足这一逻辑的选项就只有A和E.

A答案中and后面的which was明显多余,所以答案只有E了.

不过E答案个人认为也有不完美的地方. 它把原来congressional medal of honor的表语long overdue改成了recognition的定语.虽然很好地使句子变得简洁,却不知道会不会影响到句子的原意.

希望有大NN可以赐教.

请问怎么看出来E是平行的呀，俺怎么看不出来呀55

with the Congressional Medal of Honor, which was the nation’s highest military award, and which was long overdue in

两个which同时修饰honor,用and连接表现其平行关系.
