This prevents all the trouble you get when you have a group selected and part is burrowed and another part is unburrowed.

这个预防了在你有一队选中的单位中有部分钻地部分未钻地造成的麻烦。

I had three pieces of limestone on my desk, but I was terrified to find that they required to be dusted daily, when the furniture of my mind was all undusted still, and threw them out the window in disgust.

在我的桌上有三块石灰岩石头，但我却惊恐地发现，它们需要每天除尘，而我心灵中的家具还全都没有掸掉灰尘，因而我厌恶地把那三块石头扔出了窗外。

But the effect of her being on those around her was incalculably diffusive: for the growing good of the world is partly dependent on unhistoric acts; and that things are not so ill with you and me as they might have been, is half owing to the number who lived faithfully a hidden life, and rest in unvisited tombs.

但是，她的存在给周围人带来的影响曾经不可胜数地四处扩散：因为世上不断增长的善，部分地是由不具历史意义的行为决定著；而你我周围恶的事物之所以没有像它们本来会成为的那样坏，一半也要归功於那些忠实地过著隐秘的生活，如今安息在无人拜祭的坟茔中的人。
