18: GWD-29-Q39

Scientists have recently discovered that the ultrathin, layered construction of a butterfly’s wings, the same as the one making some butterflies shimmer via the phenomenon of iridescence, are enabling the insect to control how much heat energy is absorbed by its wings and how much is reflected away.

1. wings, the same as the one making some butterflies shimmer via the phenomenon of iridescence, are enabling
2. wings, which is the same one that makes some butterflies shimmer via the phenomenon of iridescence, that also enables
3. wings is the same as the one that makes some butterflies shimmer via the phenomenon of iridescence, enabling
4. wings—the same construction that makes some butterflies shimmer via the phenomenon of iridescence—also enables
5. wings—of the same construction that makes some butterflies shimmer via the phenomenon of iridescence—also enable

The key is C, but I feel enabling not good. D seems good to me, only not sure "also".  Any NN could explain? Thx

You mean change appositive phrase "the same as the one making some butterflies shimmer via the phenomenon of iridescence" to the main clause of the sentence, right?

Also, can we understand "eabling" modifies "ultrathin, layered construction"? Or we cant since they are too far away?

Thx,

考点：主谓一致；修饰（同位语、V-ing）；

为什么D 正确？
                    

心得：

如何判断本题考点？

1，先看结尾：B、D、E 3个都是将enables做动词，但有单、复数之分；再看开头，5个选项都是wings，复数；明显的主谓一致的考点；

2，C出现“
                ，enabling ”显示在考修饰，这样就要注意是否修饰歧义；

识别陷阱：

故意弄个假的主谓一致，E就是这种陷阱的代表，划线的地方wings是复数，also enable是复数，看起来很配，实际上从句的主语是construction，谓语应该是单数 enables。

C: 错，enabling前有逗号，可以就近修饰phenomenon，也可以伴随修饰主句主语Scientists，造成修饰歧异，且逻辑含义都不对；

D：用同位语插入，补充说明the ultrathin, layered construction，主干清晰，句子结构如下：

主句主语
                    谓语 + that 从句主语，同位语插入（对从句主语补充说明），从句谓语
                    宾语
                    宾语补足语。

需要更好的解答啊！
