古德通过后续观察发现不仅黑猩猩——猩猩属——能够制造和使用工具，而且从进化论来说我们最亲近的表亲会相互拥抱亲吻。

Goodall's subsequent observations found that not only did pan troglodytes - the chimpanzee - make and use tools but that our nearest evolutionary Cousins embraced, hugged, and kissed each other.

果真如此的话，通过观察与我们亲缘关系最近的灵长类动物之间的沟通交流，就可能从中发现某些线索，证明人类语言到底是怎样从咕哝有声或者打手势进化而来的。

If so, it should be possible to find clues about how human language evolved from grunts or gestures by observing the communication of our close primate relatives.

他认为“我们通过观察可以发现，大多数的梦实际上是直接把我们带回到日常生活中，而不是让我们脱离日常生活。”

For it may often be observed, apparently indeed in the great majority of dreams, that they lead us directly back into everyday life, instead of releasing us from it.

And the reason we can see that by looking at this graph is that we see that nitrogen when it's bonded is in an even lower well than we saw for hydrogen.

原因可以通过观察这幅图发现,我们看到氮在成键之后将处于更低的势阱中,对氢而言。

And when we talked about that, what we found was that we could actually validate our predicted binding energies by looking at the emission spectra of the hydrogen atom, which is what we did as the demo, or we could think about the absorption spectra as well.

当我们讨论它时，我们发现,我们可以通过,观察氢原子,发射光谱，来预测，结合能，就像我们在演示实验里做的那样，或者我们也可以观察吸收谱。
