天哪，美国人这样说英语4-49: let’s flip a coin. 让我们抛硬币来决定吧。
flip 用手指弹，轻击，按动开关
太荒唐了！
That doesn’t make any sense!
Nonsense!
That’s ridiculous!
Don’t make me laugh!
想要打赌怎么说？
Do you want to bet(on that)?你想打赌吗？
Let’s bet on who’s going to win this time.我们打赌这次谁会赢。
How about playing for a pizza?我们来赌比萨吧？
What are we going to play for?
= should we play for something?
=what should we bet for?
我们赌什么？
【小编笔记】
硬币正面通常是头像（head)， 反面是有尾巴（tail)的动物图案。
Call it in the air,heads or tails!
