it is natural that misunderstandings should occur even if the language is faultless.

问题描述:

it is natural that misunderstandings should occur even if the language is faultless.
1.The nature of human beings is similar,so it is not strange that there are some similarities of taboos between Chinese and English.这里的it is strange句型是否要用虚拟,后面跟there be.
2.It is natural that misunderstandings will occur even if the language is faultless.这里也是,要把will改should吗?

不需要虚拟语气,因为讲述的就是事实.
不需要改,同上.
