Mandara seemed to know something big was about to happen. So she let out a yell, caught hold of her 2-year-old daughter Kibibi and climbed up into a tree. She lives at the National Zoo in Washington, D.C.

And on Tuesday, August 23rd, witnesses say she seemed to sense the big earthquake that shook much of the East Coast before any humans knew what was going on. And she’s not the only one. In the moments before the quake, an orangutan (猩猩) let out a loud call and then climbed to the top of her shelter.

“It’s very different from their normal call,” said Brandie Smith, the zookeeper. “The lemurs (monkey-like animals of Madagascar) will sound an alarm call if they see or hear something highly unusual.”

But you can’t see or hear an earthquake 15 minutes before it happens, can you? Maybe you can — if you’re an animal. “Animals can hear above and below our range of hearing,” said Brandie Smith. “That’s part of their special abilities. They’re more sensitive to the environment, which is how they survive.”

Primates weren’t the only animals that seemed to sense the quake before it happened. One of the elephants made a warning sound. And a huge lizard (蜥蜴) ran quickly for cover. The flamingoes (a kind of bird) gathered before the quake and stayed together until the shaking stopped.

So what kind of vibrations were the animals picking up in the moments before the quake? Scientist Susan Hough says earthquakes produce two types of waves — a weak “P” wave and then a much stronger “S” wave. The “P” stands for “primary”. And the “S” stands for “secondary”. She said she thinks the “P” wave might be what set the animals off.

Not all the animals behaved unusually before the quake. For example, Smith says the zoo’s giant pandas didn’t jump up until the shaking actually began. But many of the other animals seemed to know something was coming before it happened. “I’m not surprised at all,” Smith said.

长时间以来，英国的医生认为戴墨镜的病人更易于消沉并患上忧郁症。对因诸如心脏疼痛和消化不良等身体不适而住院的病人进行的心理测试证实了这一联系。或许觉得周围的一切使得心理上痛苦的人选择这样的墨镜去减少视觉刺激，视觉刺激被认为是令人易发怒的。不管怎么说，人们可以得出结论，如果人们戴上这样的墨镜，就是因为戴墨镜者有消沉或患有忧郁症的倾向。 上述论证以下面哪个为假设

A．消沉在某些情况下不是由身体的有机条件造成的。

B．戴墨镜者认为墨镜不是一种把自己与别人疏远开来的方法。

C．消沉有很多原因，包括任何人消沉都合乎情理的真实条件。

D．对于戴墨镜的忧郁症患者来说，眼镜可以作为让别人看来戴镜者的健康不佳的视觉信号。

E．墨镜没有把光线变得如此黯淡以致使戴镜者的心情急剧消沉。
