标题: 请教GWD-TN24-20套18题 即GWD-29-Q39

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.

 

A.      wings, the same as the one making some butterflies shimmer via the phenomenon of iridescence, are enabling

B.       wings, which is the same one that makes some butterflies shimmer via the phenomenon of iridescence, that also enables

C.      wings is the same as the one that makes some butterflies shimmer via the phenomenon of iridescence, enabling

D.      wings—the same construction that makes some butterflies shimmer via the phenomenon of iridescence—also enables

E.       wings—of the same construction that makes some butterflies shimmer via the phenomenon of iridescence—also enable

请教:为什么选择D,那么此时句子结构如何划分,此处的破折号用法不太明白,layered前有逗号,而破折号后直    接加enables作为从句的谓语动词,这样句子结构正确吗,那其他选项错在哪?  谢谢.

后面那个破折号兼具逗号的破折号本身功能.

A里面are enabling错,要用单数形式

B错在which is,和后面的that多余.

C...enabling成了伴随状语,句子结构大错。

E,the same construction作为同位语前面的of不能要,enable要用单数
