GWD21-Q27

27. GWD21-Q27:

The electronics company has unveiled what it claims to be the world’s smallest network digital camcorder, the length of which is that of a handheld computer, and it weighs less than 11 ounces.

A.      to be the world’s smallest network digital camcorder, the length of which is that of a handheld computer, and it weighs

B.       to be the smallest network digital camcorder in the world, which is as long as a handheld computer, weighing

C.      is the smallest network digital camcorder in the world, which is as long as a handheld computer, and it weighs

D.      is the world’s smallest network digital camcorder, which is as long as a handheld computer and weighs

E.       is the world’s smallest network digital camcorder, the length of which is that of a handheld computer, weighing

这道题大家帮我分析下，答案是D，为啥是what it claims is？what引导的名词性从句是什么用法，这句话这样看有两个谓语，一个是unveil，一个是is，是我错了吧？另外撇开其他的不说，weighing这个用法对不对？

我看来unveil是主句谓语 is 是从句谓语 因此不冲突的

另外，weigh是和which后面的is 并列的，动作发出者是the smallest network digital camcorder ，而B得weighing动作发出者就变成 a handheld computer了

我不明白。如果是what it claims 是插入语的话，去掉应该不影响。

但是如果像楼上说的省略了that,但是那么that是放在unveil的后面引导宾语从句，而且是做主语的，肯定是不能省略。

突然觉得what it claims =that,觉得答案应该是E了。

A中觉得and不应该有逗号，and连接两个句子。

B中which就近修饰world了，但是逻辑主语应该指代camcorder,后面的weighting是名词，和从句不平行。

C中which就近修饰world了，但是逻辑主语应该指代camcorder

D中and前是which从句，后面是动名词，不平行。

E正确，what it claims =that，is就顺理成章了，the length of.......,weighting(有n的感觉和length对称)........共同修饰那个摄像机。

错了，不要被误导，对不起大家。还在琢磨这道题。

E中觉得有个毛病是如果用weighting和the length一起修饰那个摄像机的话，是不是中间的逗号应该用and来代替？

这样的话答案就应该是D了。and应该和逗号不同时使用而and优于逗号，我现在认为选D。

the length of which is that of that of a handheld computer的表達不符合邏輯

沒有說A的長度是B的長度這種說法，都是說A跟B一樣長。

我真的覺得GMAT是考邏輯
