A little knowledge can make a difference at a time of life or death. Do you know what to do if you find yourself in an earthquake?
lf you are inside:
Quickly move under a strong desk, a strong table or along a wall. You can also go into a small room like the bathroom. This will protect you from falling things. Do not get into a lift.
Don't stand near windows, large mirrors, heavy furniture of fireplaces.
If you're outside:
Move away from buildings and streetlights. These could fall on you. Squat(蹲下) and protect your head until the shaking stops.
After the earthquake:
Check, take care of injuries and help make sure people around you are all right. Watch out for aftershocks.
Protect yourself by wearing long pants, a long-sleeved(长袖的)shirt and strong shoes. Listen to tile radio for the latest information.

In some science fiction movies, evil robots refuse to die, no matter how hard people fight back.
Now science fiction has become science fact. For the first time, scientists have made a robot that can take a beating and keep on going. Scientists from Cornell University made the robot, which looks like a spider with four legs.
Until now, even the most advanced (先进的) robot was almost certain to break down when it was damaged (毁坏). That is because its computer inside simply doesn’t know how to make the machine work after its shape has changed. 
To deal with this problem, the scientists put eight motors (发动机) and two sensors (传感器) that read how the machine is working. They all give signals to the machine’s software. Using this information, the computer can then figure out the machine’s shape at any moment.
The new technology is a big advance in robot-making, scientists say, and it’s far from scary. It may someday help scientists create better artificial (假的) arms and legs and give new freedom to people who lose them. It might also help scientists understand how people and animals figure out their own sense of place in space.
“It has been difficult to design robots that can work well when the environment changes or when it’s damaged,” says Olaf Sporns of Indiana University in US. “With this work, we are nearer to solving this problem.”
