关于英语语法的，为什么有些逗号后可以用that 有些不可以啊

Question

能具体讲解一下么 我快晕死了

Answer 1

1）that表示结果状语从句时不能加逗号。
2）两个以that引导的宾语从句，后一个that前应加逗号。追问

能用一些具体例子讲解么 这样比较好理解些

追答

例句
1、连接宾语从句可以加：
Voices now come from many quarters insisting that the science about global warming is imcomplete,(that) is's OK to keep pouring fumes into the air until we know for sure.

2、such ...that不加：
You are such a responsibility girl that I firmly believe that you can be a good teacher.

that一般只引导限制性定语从句，所以不能放在逗号的后面，但有时它也可以引导非限制性定语从句，这个非限制性定语从句表示的内容比用which、 who引导的非限制性定语从句显得重要一些，如：
Age，that lessens the enjoyment oflife，increases our desire of living.
希望我能帮助你解疑释惑。
