As a matter of fact... 不瞒你说……
用法透视：
这个句型的含义接近"in fact"，意思是“不瞒你说；其实；实际上”。做插入语单独使用。
支持范例：
1. As a matter of fact, we were just talking about you when you came in. 不瞒你说，你进来时我们正谈论你呢。
2. As a matter of fact, I was the one who did it. 其实，那件事是我做的。
3. I finished it yesterday, as a matter of fact. 实际上，我昨天就完成了。
会话记忆：
A: I wish I could unsay the sharp words to him. He must hate me very much.
真希望我没说那些过分的话，他一定恨死我了。
B: He doesn't mind. As a matter of fact, he's very pleased.
他没介意。事实上，他还挺高兴的。
A: Oh, really? Thank godness. 哦，是吗？ 谢天谢地!
