GWD15套27题. GWD21-Q27:

Theelectronics company has unveiled what it claims to be the world’s smallestnetwork 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 networkdigital camcorder, the length of which is that of a handheld computer, andit weighs      

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

C.    is the smallest network digitalcamcorder in the world, which is as long as a handheld computer, andit weighs

D.   ! isthe world’s smallest network digital camcorder, which is as long as a handheldcomputer and weighs

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

这道题选d，但是我真的没办法理解d的话，整句句子的结构是什么，what is claims在句子里面做什么成分！主语从句？插入语？省略了什么呢？如果用to be错在哪里呢，我当时就错选了b

另外还有一些困惑的语法点，比如后面weighing和weighs两种用法都可以么，有好坏之分吗

这样说来也很奇怪，what后面的句子如果做整句话的宾语从句，，那么what就是从句中的主语，明显不合理吧。。。再不济也应该用that而不是what，求解啊这道题想的我好心累，谢谢！！

what it claims to be 后面说的内容必须是关于company ITSELF.  TO BE 这种修饰是要表示离开它最近的一个 ...

啊，懂，可以理解b了，那么如果选d， is前面的主语是what 引导的主语从句么？然后整体作为unveil的宾语从句？谢谢~
