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 ing before it happened. “I’m not surprised at all,” Smith said.

解析：这篇文章主要讲了在地震前动物们的表现，有些动物对地震敏感，而有些动物对地震没有察觉。
【小题1】根据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.故选A。
【小题2】根据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.”故答案应为A。
【小题3】根据One of the elephants made a warning sound. And a huge lizard (蜥蜴) ran quickly可猜出“cover”意思是居所，故选B。
【小题4】根据For example, Smith says the zoo’s giant pandas didn’t jump up until the shaking actually began，故选A。
【小题5】通过全文以及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 ing before it happened. “I’m not surprised at all,” Smith said.
故选C。
