Hello, ladies and gentlemen, welcome to my program, this is Ukki. 嘿，大家好，欢迎收听可可英语独家专栏节目"E聊吧"，我是Ukki. In today's program we are going to learn an expression "Don't let the cat out of the bag. 要保密哦！"
【讲解】let the cat out of the bag是一句常用俚语，表示"泄露秘密"。
Their engagement was to be a secret but the ring on her finger let the cat out of the bag.
——You shouldn't have told Sam about the party. I had planed to give him a surprise.
——I didn't told Sam. I think it's Lily who let the cat out of the bag.
OK, that's what we learn today, please remember me, this is Ukki and remember what we have learned today "Don't let the cat out of the bag.要保密哦！"
So much for today's program, see you next time and have a nice day, bye~~
