可以说"They have too much free time." 或者 "They are too idle."

"Free time" 指的是人们有自由选择如何使用的时间，而 "idle" 则指人们太闲，不做事情。

下面是一些例句：

"I don't have much free time because I have a lot of work to do."（我没有太多自由时间，因为我有很多工作要做。）

"I'm feepng kind of idle today. I don't really have anything to do."（今天我有点闲，我真的没有什么可做的。）

"I can't bepeve how much free time you have! What do you do all day?"（我真的不敢相信你有这么多自由时间！你一天做什么？）

"I'm so bored. I have way too much idle time on my hands."（我太无聊了。我有太多闲着的时间。）
