Having an understanding of culture as well as a shared language is essential.
还有问题:
1.为什么understanding前用an?都不是发元音啊
2.为什么是"is" essential?不是有两个吗aving an understanding of culture 和a shared language 不用are?as well as用就近原则吗?那用就近原则的情况都有哪些,详细告诉我啊,谢~
understanding “u”的发音/?/是原音的（发/ju/的时候非原音），u的发音不能全当本身字母的发音来判断，要看在那个单词里的发音。as well as 是个插入语，不是主语的一部分，所以谓语动词不需要考虑它后面的东西了，这句话还可以是这样的：Having an understanding of culture is essential as well as a shared language....
