Prep 1-92
Research has shown that when speaking, individuals who have been blind from birth and have thus never seen anyone gesture nonetheless make hand motions just as frequently and in the same way as sighted people do, and that they will gesture even when conversing with another blind person.
(A) have thus never seen anyone gesture nonetheless make hand motions just as frequently and in the same way as sighted people do, and that

(B) have thus never seen anyone gesture but nonetheless make hand motions just as frequently and in the same way that sighted people do, and

(C) have thus never seen anyone gesture, that they nonetheless make hand motions just as frequently and in the same way as sighted people do, and

(D) thus they have never seen anyone gesture, but nonetheless they make hand motions just as frequently and in the same way that sighted people do, and that

(E) thus they have never seen anyone gesture nonetheless make hand motions just as frequently and in the same way that sighted people do, and

答案A

我的问题是：individuals who have been blind from birth and have thus never seen anyone gesture nonetheless make

hand motions just as frequently and in the same way as sighted people do 这部分是插入语的功能吗？

1、如果是，那么句子主干变成：Research has shown that when speaking and that they will gesture even when conversing

with another blind person.是不是很奇怪了？

2、如果不是，那第一个逗号是什么作用啊？

对于这题的句子结构一直没看懂，还请NN帮忙解答，谢谢！！

把第一个that后面看成整句话
when （individuals）speaking,  individuals...make hand motions just as frequently and in the same way as sighted people do...
个人觉得，这个逗号用来分开when的时间状语从句和主句还满正常的
比起不用逗号更加清晰吧……

谢谢及时解答.  ：）

其实我不太懂是句子结构，就像bendrift分的这样[ that when speaking, individuals (who have been blind from birth and have thus never seen anyone gesture )nonetheless make hand motions just as frequently and in the same way as sighted people do, ]   那里面speaking后面为什么要用个逗号啊？不太理解…

其实从另一条思路来说 as...as
由此排除B,D,E

然后宾语从句平行，that不能省
排除C

答案是A

这样做应该也可以的

解题思路:
1.Research show that..... and that.....
并行宾语从句,所以只看A和D
2.D错 因为 who后面是定语从句 who  have....and have.....是定语从句部分.
加上they 导致who ...have ...and they的前面部分缺失句子谓语成分.
所以选A
