Earthquake rescue robots have experienced their final tests in Beijing.Their designers say with these robots,rescuers will be able to buy more time to save lives during an earthquake.
This robot looking like a helicopter,is called the detector-bot.It’s about 4 meters long,and it took about 4 years to develop the model.Its main functions are to collect information from the air,and send goods of up to 30 kilos to people trapped by an earthquake.
This robot has a high definition 360 degrees panoramic (全景) camera.It can work day and night and will also be able to send the latest pictures from the quake area.
Dr.Qi Juntong,Chinese Academy of Science,said,“The most important feature of this robot is that it doesn’t need a distant control.We just set the destination (目的地) information on it,and then it takes off,and lands by itself.It flies as high as 3,000 meters,and as fast as 100 kilometers per hour.”
This robot has a different function—it can change as the environment changes.Its main job is to search for any signs of life in places where human rescuers are unable to go.
As well as a detector (探测器) that finds victims and detects poisonous gas,a camera is placed in the 40 centimeters long robot, which can work in the dark.
Another use for the rescuers is the supply bot.With its 10-meter-long pipe,people who are trapped in the ruins,will be able to get supplies including oxygen and liquids.
Experts have said that the robots will enter production,and serve as part of the national earthquake rescue team as soon as next year.

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 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 (monkey like 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.
1.Why did Mandara act strangely one day?
A.Because it sensed something unusual would happen.
B.Because its daughter Kibibi was injured.
C.Because it heard an orangutan let out a loud call.
D.Because an earthquake had happened.
2.According to Brandie Smith,_____________.
A.many animals hearing is sharp
B.earthquakes produce two types of waves
C.primates usually gather together before a quake
D.humans can also develop the ability to sense a quake
3.Which animal seems unable to sense quake?
A.A giant panda. B.A flamingo.
C.A lemur. D.A lizard.
4.What is the best title for the passage?
A.How animals survive a quake
B.How animals differ from humans
C.How animals behave before a quake
D.How animals protect their young in a quake

Have you heard an old saying “The grass looks greener on the other side of the fence”? It means other places often look better, more interesting than the place where you live. “Let’s go to KFC for dinner and then watch some Japanese cartoons!” We all know it: more and more Chinese kids love American and Japanese food and movies. Some people worry that young Chinese are beginning to feel that way. They see young Chinese ignoring（忽视）Chinese culture and, instead, buying Japanese cartoon books, watching Korean soap operas and even celebrating western holidays.
Foreign books and soap operas are good, but Chinese writers and actors are just as good. As for holidays, Christmas is nice, but it can never have the meaning for Chinese that Spring Festival has, and the West has nothing to compare with the Mid-Autumn Festival. China has lots of cool things in its culture: calligraphy, Beijing Opera, quick meals on the streets, and even Jay Chou! And let’s not forget the part of Chinese culture I like best: its friendliness. Not all countries are as warm as China.
It’s good to enjoy other cultures and learn from them, but they can never replace your own culture. It’s good to look on the other side of the fence, but make sure you take a good long look. You will find that the grass isn’t always greener.
Although some people become worried about that, I don’t think they should. Will we get more powerful without learning from other countries? Will Chinese people live more happily without American fast food? Besides, it’s fun to learn about different cultures. Chinese kids can learn about other cultures and have fun, but they also need to learn more about their own culture. Be proud of Chinese culture and of being Chinese!
