对话文本
Ted: Mom, Amber is here to lend a hand with the cookies.
Susan: hi Amber. Nice to see you again.
Amber: good to see you too, Mrs. Johnson.
Susan: that’s an interesting hairstyle.
Amber: thanks. I’m glad you think it’s cool. Blue hair is all the rage this season.
Susan: well, I’m going to take a break now and let you kids take over.
Ted: don’t worry, Mom. Your business is in good hands with Amber. She really knows her stuff.
Amber: that’s true. I used to work at Mrs. Field’s Cookies in the mall.
Susan: you don’t work there anymore?
Amber: no, I got fired. I have a real sweet tooth, and they told me I was eating too many cookies.
Susan: well, I am sure you haven’t lost your touch.
Amber: I might be a bit out of practice.
Ted: Mom, you can watch Amber bake if you want. You might pick up a few tricks of the trade.
Amber: yes, feel free. As a singer, I’m used to performing before an audience!
Susan: thanks, but I’m going to get out of the way. You know what they say: too many cooks spoil the broth!
Amber: will I see you later tonight?
Susan: yes, I’ll be back in a few hours.
Ted: Mom, why don’t you just call it a night and go to bed. You’ve been working your tail off all day.
