We use passwords(密码)to keep our personal information secret and safe, but some passwords we use may not be as reliable as we think.
Splash Data, a computer security company, recently released a list of the 25 worst passwords of 2011.This list is based on the research of hackers’ files containing stolen passwords. According to the list, “password” is the worst and most common password. Many others on the list are numbers in order either forward (for example,1234) or backward. Letters on the keyboard in order, such as “qwerty” are also common, as well as some first names and animals. “Hackers can easily break into many accounts(账户) just by trying common passwords again and again, ” said Morgan Slain, CEO of Splash Data.
How can you make a strong password? It should be eight characters or more, with a mix of letters, numbers and symbols. One way to create a long and easy-to-remember password is to separate short words with spaces or numbers. Having safe passwords is necessary for surfing the Internet safely. But it’s not the only thing you must do to keep safety online. Here are some other web safety tips:
●Never give out information that will allow someone to find you offline. That includes your full name, address and phone number.
●Don’t include your real name as part of your online screen name.
●Never meet people you met on the Internet in person. If you insist on breaking this rule, meet in a very public place and consider taking an adult with you.

“I hate school, and I’m not going back!”Have you ever had that thought?
Lots of kids have had. Usually this feeling doesn’t last long. But what if you feel this way too much? If you are stressed out, you might have a hard time making decisions. In the morning, you can’t decide what to eat, what to wear, or what to take for lunch.Sometimes it’s a problem with your classes and schoolwork. Maybe the work is too easy and you get bored. Or maybe the work is too hard, or you don’t feel as clever as the other kids. Reading may be difficult for you, but you are asked to do a lot of it. You may be getting farther and farther behind, and it may seem that you will never catch up with others. When you know why you don’t like school, you can start taking steps to make things better
It’s a good idea to talk to someone about your problems at school. Your mom, dad, friends, teachers, or even classmates will be able to help you.
Another good idea is to write down your feeling about school. For instance, keep a diary or just write in a notebook. It’s a great way to let out emotion that may be stuck inside you. And you don’t have to share(分享)what you have written with others.
The next time you find yourself disliking school, this will also help you:
Make a list of everything you dislike or enjoy—even there is only one thing. See what you can change on “don’t like” list.

Recently,a solar powered(太阳能动力的)plane took to the sky for the first time. It had passed an important test on the way to travel around the world. The plane took off from an airport in Switzerland(瑞士)at 45km an hour. It slowly rose above the fields and into the sky.
“There has never been an airplane of that kind that could fly — never an airplane so big, so light, using so little energy,” said Bertrand Piccard, a leader of the project.
During the 90-minute flight, the plane did several turns. It climbed nearly 1.6k above the countryside. Engineers plan to test a night flight before July. Then they will use the results of the tests to build a second plane. They plan to travel around the world in that plane in 2012.
The plane flies at 70 km an hour. That is faster than a bike and slower than a car. Piccard and pilot Andre Borschberg will take the plane around the world. The pilots will keep the plane in the air for up to five days at a time. We want to fly it day and night with no fuel (燃料),” Piccard said
How long did the first flight of the solar powered plane last?
