In other words, they may as well save half a breath and simply shout " Treat! "

换句话说，他们不妨省下半口气，干脆喊一声“给糖！”

【save】我想解释，但她叫我还是省点口水吧。

And I think we're so judgmental of how other people look and really we should just save our breath really and our time, and just see how beautiful everybody is and how beautiful the world is.

我认为我们总是对别人的长相评头论足，所以我们应该省下力气，省下时间，去看看每个人有多漂亮，看看这个世界有多美丽。

" Fred and George have got the gold—spent a good bit of it, too, by the sounds of it—and I can't get it back from them and I don't want to. So save your breath, Hermione."

“弗雷德和乔治已经拿到了金子——看来已经花掉不少了——我投办法从他们那里要回来，我也不想这么做。所以省口气吧，赫敏。”
