如果你坚持每星期在冰箱里防止两升瓶装的可口可乐和雪碧，那么你将无法合理地告诉孩子，他每周只能喝一小杯苏打汽水。
You cannot reasonably tell a child he is allowed only one soda a week if you keep two-liter bottles of Coke and Sprite in the refrigerator.
你也可以只为自己要一杯雪碧并说你在喝的是伏特加调的雪碧。
You may also just get yourself a glass of Sprite and say you're drinking vodka Sprite.
苏珊：听起来很不错。谢谢。那就要加大号的吧。我想来一杯雪碧，就不要可乐了。谢谢。
Susan: that sounds good. Thanks. I'd like that. Actually I'd like a Sprite instead of a Coke. Thanks.
