which后面is as long as和weighs并列

视频里面这位老师讲的真心不错，比founder讲的更好。 hhh

weighing作状语修饰最近的动词，B错
A与C的主句都是the electronics company has unveiled what it claims....不能和it weighs less than 11 ounces对等

1，为什么讲解视频里面说B选项的which是指代camcorder啊？不是应该就近指代 the world吗？
2，所以B选项这个which有没有指代错误呢？
--

The electronics company has unveiled what it claims is the world's smallest network digital camcorder.
what是个名词，不能引导定语从句，把what替换成something
Right: This is the thing that you want.
Wrong: This is the thing what you want.
Right: This is what you want.

claim的内容应该是一件事，而非是一个东西。what it claims is the ...= it claims (that) something is the world's...然后进行倒装，something that it claims is

B.weighing有做cconputer非限制性定语的歧义

claim的用法是 A claims to be B; A claims B is C；这句话的用法是it claims what is the camcorder;

1) It claims为插入成分，这一现象大多数考生在此处为第一次遇到，因此很多考生会认为claim的正 确搭配为claim to do something，因而排除BCD选项。实际上is和to be在选项中都是正确的表达： 若为is，可理解为it claims是插入成分;若为to be，则可理解成what it claims to be…这一大家都 很熟悉的表达。

平行结构需要关注的不仅仅是表达结构上的平行，意思的平行高于表达结构平行；
错选B，Claim声称，弱约束力；允许了weight做伴随，这是不对的；

They are claiming that it IS something - not that it "to be" something - so, no, we wouldn't use "to be" here. We'd say "the company has unveiled what it claims is the world's smallest..."

I could say, though, "she claims to be a violinist, but I've heard her play and she's terrible." So there are circumstances in which you could use "claim to be" - but this isn't one of them.

错选了B, 此处weighing应该涉及指代不明？

选错了，开始认为claim有较强约束力，排除了CDE，最后答案为E，只能理解为B选项中，weighing既可以做状语从句，逻辑主语为camcorder，也可以做分词短语作为定语修饰 handheld computer。但按照逻辑指代 ，还是不愿意承认B的which有修饰 world的歧义的，因为觉得可以根据逻辑跳跃修饰camcorder。而且what it claims is也没什么非错的理由。
不知道这样理解答案对不对。

what it claims is...＝it claims what is...

claim的用法：A claims to be B／A claims B is C
