这道题给的答案是C,但是我有点儿疑问,后面的介词应该不是用with的吧?nevertheless做副词修饰creating sounds,creating sounds作为lack vocal cords的伴随,另外有人说后面produced前面应该用is不应该用are,但是我觉得这里的A of B形式和平时用的有些区别,这里的A的是量词,是后面的这些声音被produced了,而不是system被produced了,所以应该用are,最主要A里面用的介词是by,所以我觉得正确,大家来讨论下吧

1.伴随:
不是有个逗号,加个ing就是伴随这么随便的。意思逻辑也得说通才行。刚学会从语法上区分伴随状语的人很容易犯这个错误。

creating sounds怎么伴随lack vocal cords?

2.system是量词??!

3.with没问题。
