A.    it hampers the ability of some children for distinguishing discrete sounds and words and, the result is, to make

B.    that it hampers the ability of some children to distinguish discrete sounds and words and, as a result, to make

C.    that it hampers the ability of some children to distinguish discrete sounds and words and, the result of this, they are unable to make

D.    that it hampers the ability of some children to distinguish discrete sounds and words, and results in not making

E.     as to hamper the ability of some children for distinguishing discrete sounds and words, resulting in being unable to make

想问一下为什么选A而不选D的~谢谢~

B.    that it hampers the ability of some children to distinguish discrete sounds and words and, as a result, to make

D.    that it hampers the ability of some children to distinguish discrete sounds and words, and results in not making

results 的主语应该是conversational pace或者是study, 但是任何一个都不合逻辑。

同问,有NN能把其他4个选项为什么错都分析一下吗?

自己先把自己想得写下来,一起讨论下:

C的错处是不是在于they指代不清?可以指代children,也可以指代sounds and words.

A在于so…that没有全部出现

D的错:按照D的思路,hamper和result都是it的谓语动词,但是hamper后面的内容跟result后面的内容明显在形式上不对称

E:being错
