在英语中，"不能丢玩具"可以用"Don't throw toys"来表达。

这句话的来源可能源于人们希望小孩子不要把玩具扔出去，或者是希望大家不要把玩具当作垃圾丢弃。

下面是一些英文例句，以及它们的中文翻译：

"Please don't throw your toys on the floor. It's not nice to leave them there for someone else to pick up." (请不要把你的玩具扔在地板上。留着让别人捡起来不好。)

"Don't throw your toys out of the playpen. It's not safe for them to be on the ground." (不要把你的玩具从婴儿围栏里扔出去。它们在地上并不安全。)

"It's important to take care of our toys and not throw them away. We can donate them to children in need if we don't want them anymore." (照顾我们的玩具很重要，不要把它们扔掉。如果我们不再想要它们，我们可以把它们捐给需要的孩子们。)
