[限时检测] [限时30分钟] 阅读理解 A Mandara seemed to know something big was about to happen.So she let out a yell，caught hold of her 2­year­old daughter Kibibi and climbed up into a tree.She lives at the National Zoo in Washington D．C. And on Tuesday，August 23rd，witnesses said 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 (monkey­like animals of Madagascar) will sound an alarm 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 birds) gathered before the quake and stayed together until the shaking stopped. So what kind of vibrations(震动) were the animals picking up in the moments before the quake？Scientist Susan Hough said 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 thinks the “P” wave might be what sets the animals off. Not all the animals behaved unusually before the quake.For example，Smith said 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.
