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.

Spring is an inviting season for outdoor activities. But be careful—the warm weather is also a hotbed for viruses(病毒) and disease.  

This March, the influenza(流行性感冒) A(H7N9) virus hit Shanghai, Anhui, Jiangsu and Zhejiang. It was reported that by April 11 at least 35 people had been infected (被感染的) with the H7N9 virus, and nine of them had died.

The influenza A (H7N9) virus is one type of influenza A H7 viruses. Influenza A H7 viruses normally spread among birds.

This is the first time human infections with H7N9 viruses have been reported in China. Earlier reports were about H5N1 and H1N1.

All the three viruses are influenza A viruses but they are not the same. H7N9 and H5N1 are animal influenza viruses that could infect people. However, H1N1 viruses can be divided into two groups. One group can normally infect people and the other normally infects animals. Also, H1N1 can spread from human to human, but H7N9 probably can’t, according to the World Health Organization (WHO).

Most people infected with H7N9 looked like they had the common flu. Some people had bad pneumonia(肺炎). They suffered from a fever, a cough and shortness of breath.

But don’t be afraid – it is not easy to be infected with the virus. One of the possible reasons is close contact with sick poultry (家禽) waste. People may also be infected through breath, according to National Health and Family Planning Commission.

Here are some tips from the WHO that can protect you from being infected.

Wash your hands with soap and running water before you eat, after you use the toilet, and after touching animals or animal waste.

When coughing or sneezing cover your mouth and nose with a mask(口罩),tissue(纸巾) or a sleeve.

Get a good rest and do exercises, which will help make your body strong enough to stand up to the virus.
