然后，用户可以把一些东西直接放进球里，比如一盏灯，或者一个手机充电器，这样他们就可以从球里获得能量。

Then the user can put something directly into the ball, like a lamp, or a mobile phone charger so that they can get energy from it.

当食物短缺时，反刍动物比非反刍动物寿命更长，因为反刍动物可以从同样的食物中获得更多的能量。

When food is in short supply, a ruminant can last longer than a nonruminant because it can derive more energy out of the same food.

如果你在网上买票，你可以从项目中获得“绿色能量”。

If you buy tickets online, you can get "green energy" from the project.

And instead of having the electron giving off energy as a photon, instead now the electron is going to take in energy from light and move up to that higher level.

与电子以光子形式施放能量不同,我们现在要从光中,获得能量到一个更高的能级。

And we can think about here we did get that energy for electron promotion that I mentioned before 2p where we moved the electron from the 2 s to the 2 p.

我们可以考虑,我们从哪里,获得了能量使电子,从2s激发到。
