三句英文句子的改错Do you know what Dolphin vocal sounding i

网友回答

should not have 改成 can not have got
试看：should not have got 意思：本不应该有
can not have got 意思：不可能有
很明显,句中是指 人类不可能达到的E8
======以下答案可供参考======
供参考答案1:
do you know what dolphin vocal sound is?
Let us enjoy Mariah Carey's classical song, and you will know it.
it's said that the highest pitch in this song, which human beings should not have got, got E8.
供参考答案2:
1.sounding 改成 sound
2.and 改成 then
3.which 改成 that,因为是含最高级highest的定语从句。should not have got 是虚拟语气，意思是本不应该达到的，但是却在这首歌里达到了。
供参考答案3:
三楼的改成that 是不对的，因为那是个非限定语从句，只能用which来引导。
