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

答案是B.这里which是跳跃修饰? A错是否因为the length of which is that of a handheld computer, 把camcorder的长度说成是handheld computer的长度了,而不是象B中用 as long as 作比较.?

不是不可以跳跃修饰，关键看跳跃之后会不会产生修饰歧义，即既可以修饰这个，又可以修饰那个。

这里不存在这个问题，因为which修饰的是what引导的名词性从句，把整个句子看作一个名词，作为修饰对象。

反对,那么没有错,是后面多了个it,

总结里，这题给的是d，但我还是觉得是a

company has unveiled后看答案是不定式或宾语从句

如果是宾语从句的话，应该有that引导啊，c d e都没有that，what it claims在这里是后面那一驼的主语，所以不能担当引导宾语从句的角色，只有a和b，a的it指代不明确，所以我就选了b了。但是听大家说weighing有歧义，觉得也有道理。

这题讨论少，希望大家多发表意见啊。

支持D，在NYtimes上搜了一下，发再有N多What it claims is 的用法。

拿一个来作证

該題答案是C，我請教過一位美國籍的教授了。

也許，大家在 unveiled 後面加個that，句子結構就清楚了。
