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

1：请问为什么是用weighing，而不是用and的并列结构呢，答案是B，

2：B的which指代的是哪一个呀，指代world不通啊，如果是跳跃指代，有什么标志能看出是跳跃修饰的吗，如果没有不就可以说是指代不清了吗

3：划线前面的what的用法有什么讲究嘛，我当时是选D，觉得是what( it claims) is.......，但看答案意思是claim to be的结构，这个what我就不懂是个什么意思了

谢谢大家指点

自己顶一下

记得GWD还是prep里有个类似的题目 答案是D

答案好像选B吧，是prep里面的

be claimed to be 比较合适吧

可以直接加is吗

乱了都，谢谢LS几位
