One day Susan was not going to be able to move when she came back from the advanced aerobics class.
Richard believed that he could do it and not feel a thing!
某天Susan 上完高级有氧课程回来之后，觉得非常累。Richard 觉得这课程对他来说完全不是问题，小菜一碟。
Susan made a bet with Richard. If Richard can go one hour in aerobics class and she would cook for the entire family.
于是Susan 和Richard 打赌，如果richard 能够坚持一个小时的有氧课程，Susan就为全家人做饭。
A piece of cake小菜一碟
notfeel a thing! 丝毫不累！
The beginner's class was too easy for me. 初级课程对我来说太容易了。
Too easy for you? 对你太容易了？
No problem. 小事一桩。
Easy.No sweat. 当然。小事情。 绝无问题。
