请问句子在哪里停顿？（句子在问题补充说明中）

They do not know that//wasting time means /wasting part of their own life.
(备注：//大停顿 /小停顿）
他们不知道，浪费时间意味着浪费他们自己生命的一部分。

They do not know that/ wasting time means/ wasting part of /their own life.

这句话需要停顿吗？一口气就说完了，寒~

They do not know that
wasting time means
wasting part of their own life

不用停顿吧
