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.
wings, the same as the one making some butterflies shimmer via the phenomenon of iridescence, are enabling
wings, which is the same one that makes some butterflies shimmer via the phenomenon of iridescence, that also enables
wings is the same as the one that makes some butterflies shimmer via the phenomenon of iridescence, enabling
wings—the same construction that makes some butterflies shimmer via the phenomenon of iridescence—also enables
wings—of the same construction that makes some butterflies shimmer via the phenomenon of iridescence—also enable
题目分析:
略。
选项分析:
A选项:划线部分的谓语动词are enabling的主语是construction,它是一个单数名词,因此本选项主谓不一致。
B选项:本选项在discover引导的宾语从句中没有主句。连词which和that分别引导了两个定语从句。
C选项:划线部分最后的enabling the insect to control是伴随状语,其会就近修饰makes some butterflies shimmer句。其主语为the one。但在逻辑上,发出enable这个动作的应该是鸟的construction,而不是蝴蝶的construction。
D选项:Correct. 本选项在语法和逻辑上均是正确的。
E选项:主谓一致错误同选项(A)。
我觉得C是错在改变了intended meaning,这句话的重点在enable后面,如果变成ing就成了没有必要存在的部分了
ultranthin,layered,超薄分层的两个都是形容词修饰这个construction得,所以enable的主语是construction单数
这个题用排除法很容易得到答案,不过整个句子的结构有一点不明白,ultrathin, layered...wings--,这里的同位语,后面没有逗号没有问题吗?是因为有了--所以可以省略?
此题宾语从句的主语应该是construction吧?ultrathin貌似是形容词,和layered一起修饰constrction的。

c选项,that引导的是一个句子啊,为什么说没有主句?
解析已更新。
所以“宾语从句”可以只是一个词?比如这句中的 ultrathin
老师我明白了,这是一个形容词……不是名词……所以 that 引导的 “宾语从句” 是 the ultrathin, layered construction of a butterfly's wings (blah blah)
