If you have only three minutes to get something that you can take from your home, and the other things are lost forever, what will you take? The following information will help you.
|
B.O.B. |
B.O.B. is short for Bug-out Bag (求生背包). It's a bag with a collection of things that are needed for life in it. |
|
Reasons to use a B.O.B. |
When disasters like earthquakes and heavy rainstorms happen, many people will have to run away from their homes and they may not return for a long time. They need to continue to live without food, water or a shelter in some unexpected situations. |
|
Things in a B.O.B.
|
A sleeping bag, or at least a thin quilt. Drinking water. High-calorie foods, such as chocolate and biscuits. Necessary medicines. Something for making a fire, and a small pot to boil water or cook A few basic tools like a knife and some ropes. A flashlight. Money. A copy of all your important papers. (Be sure to make a B.O.B. as light as possible.) |
|
Places to keep a B.O.B. |
You should put a B. O. B at a place where you can get it conveniently when disasters happen. Your home, your car, or your office can be a good place to put it. |
A B.O.B. is very helpful to the people in need. You'd better prepare more than one B.O.B. if possible. Then think of the difference a B.O.B. will make if those disasters happen. So prepare one now.
Many people know that rubbish is a big problem on planet Earth. What many people don't know is that junk (垃圾) has become a problem in outer space too.
According to BBC News, there are more than 22, 000 pieces of space junk floating around the earth. And these are just the things that we can see from the surface of the earth by telescopes (望远镜). There are also millions of smaller pieces of junk that we can't see.
Objects, like bits of old space rockets or satellites, move around the planet at very high speeds, so fast that even a very small piece can break important satellites or become dangerous to astronauts. If the tiniest piece of junk crashed into a spaceship, it could damage the vehicle.
To make things worse, when two objects in space crash, they break into many smaller pieces. For example, when a U. S. satellite hit an old Russian rocket in 2009, it broke into more than 2,000 pieces, increasing the amount of space junk.
To reduce additional space junk, countries have agreed that all new space tools can only stay in space for 25 years at most. Each tool must be built to fall safely into the earth's atmosphere after that time. In the upper parts of the atmosphere, it will burn up.
Many scientists are also suggesting different ways to clean up space junk. In England scientists are testing a metal net that can be fired into space junk. The net catches the junk and then pulls it into the earth's atmosphere to burn up. The Germans are building robots that can collect pieces of space junk and bring them back to Earth to be safely destroyed.
"The problem is becoming more challenging because we're sending more objects into space to help people use their mobile phones and computers," says Marco Castronuovo, an Italian space researcher.
"The time to act is now. The longer we leave the problem, the bigger it will become," he says.
Don't be too surprised if you see a car going down the road without a driver in Beijing these days. Last month, Baidu began to test its self-driving cars on open roads in Beijing.
Since then, companies like Tesla, Uber and Baidu have been working to produce and test their own self—driving cars.
Self-driving cars are safer than regular cars. They can remove the stress of driving and allow disabled or blind people to get around more easily.
In one test, researchers pointed a laser pointer (激光棒) at the car's sensors (传感器) while it was moving. The car mistakenly thought that the laser beam was in its way and slowed down or changed the direction.
The software that is used to direct the cars may not be safe enough. When we use our computers or smartphones, they sometimes crash (崩溃) without any reason. But if this happened to a self-driving car, the result could be deadly. Improvements to the software could be a solution to this problem.

A. At times, it may break down. B. Self-driving cars began to develop in 2010. C. It might be one of Baidu's self-driving cars. D. But self-driving cars have their own problems as well. E. And they are more environmentally friendly than regular cars. |
