Dolphins lack vocal cords, nevertheless creating sounds: a complicated system of whistles, Squeaks, moans, trills, and clicks are produced by sphincter muscles inside the blowhole.
A: nevertheless creating sounds: a complicated system of whistles, squeaks, moans, trills, and clicks are produced by
B: nevertheless creating sounds: they produce a complicated system of whistles, squeaks, moans, trills, and clicks with
C: but they do create sounds, producing a complicated system of whistles, squeaks, moans, trills, and clicks with
D: but they do create sounds, a complicated system of whistles, squeaks, moans, trills, and clicks being produced
E: but nevertheless creating sounds: a complicated system of whistles, squeaks, moans, trills, and clicks produced by


我觉得根据题目，是muscles produce a complicated system 的，并不是dolphins produce的，所以这样就变成B,C肯定都去掉了

可大家争议的就在B,C。。。居然被我都去掉了。。。

求NN告诉我是怎么回事。。。难道不应该考察动作发出的主语是谁么？？？


GWD31-39
From 1965 on, the region’s standard of living has soared, but also unemployment and prices,

C. but so have
E. but so did

唯一的疑问，C不需要补出变成but so have done...么？ have done不是应该要省略一起省，要补出一起补的么？就像本题：

According to public health officials, in 1998 Massachusetts became the first state in which more babies were born to women over the age of thirty than under it.

A.than
B.than born
B就是错的，要补就应该were born一起补。

救命啊救命啊。。。

求NN随便回答哪一题吧！！！

第一题我选C。
sound system是dolphin用muscles来produce的，这样的逻辑更合理。
“这个声音是小明捏着鼻子发出来的。”-->那么声音是鼻子发出来，还是小明的嗓子，还是小明呢?所以……主语应该还是dolphin。

第二题选C。
比较中省略的原则是重复的、省略了不会引起歧义的就省略。并不是have done一定要同在同省的，其实如果动作相同，更多情况是就补出表达出了时态、单复数的助动词来即可。
=======
born under it，那么under it是修饰born了，it指代30 years old，"30岁以下被出生"，逻辑上是很absurd的。

这里没有必要去纠谁produce……你能说我的声带发出声音和我通过声带发出声音哪个错了么？
还有这个题目在网上有另外一个版本。其中的C变成了
C: but they do create sounds, producing a complicated system of whistles, squeaks, moans, trills, and clicks being produced
而其他选项都没有变。这么一来就只能选B了。奇怪的题目

谢谢ls两位！！！！！！！！！！

我再多问一句
如果是
fanny has bought a cake, and jim has bought a bike.
jim那句可以只留一个has么？
是不是就has bought同在同省呢？
