插入语开头字母是大写还是小写?

问题描述:

插入语开头字母是大写还是小写?

In no country other than China,It has been said,is the problem of society more serious.
In no country other than China,it has been said,is the problem of society more serious.
这两个哪个对啊?

第二句对
当然用小写,it has been said是插入语,前后都有逗号,在句子中起补充说明作用,不可能是大写的. 除非是特有名词或是引用的短语.
