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.

Did you forget your password (密码) or your ID? Well, you’ll never forget your face. Using your face as your ID is quick and convenient. You could take the subway or get on the plane with just your face alone. This is how facial recognition (人脸识别) works. It has also been used to catch criminals. The American pop singer Taylor Swift even used the technology to find out the person who did something bad to her at her concerts.
In China, facial recognition systems(系统) have been used in many areas. In Zhengzhou, people can now get on the subway by using facial recognition technology. They just need to connect their online payment systems to the subway’s smartphone app. Students at certain schools can pass through the school’s gates by scanning (扫描) their face.
However, there are no laws to control the use and collection of facial information now, according to Zhao Zhanling, a researcher at the China University of Political Science and Law. Many people are worried about the collection and use of the information by governments and companies. Why is it necessary to collect data about your face and what will the data (数据) be used for? These are some common questions about the facial recognition.
“I feel uncomfortable because I don’t know how the company is using my facial information or whether it will be leaked. If so, my secret information will become known to the public.” Feng Yi, a tourism company worker, said about Zhengzhou’s subway smartphone app. Leaks are a problem that worries people because companies have always failed to protect users’ data. When someone steals your personal information, you can change your bank card and password, but can you change your face when your facial information is stolen?
As facial recognition is used more and more in our daily lives - from schools and subways to street comers and smartphones - we must ask ourselves whether or not this new technology is worth the risk.
1.The example of Taylor Swift is to ________.
A.show the popularity of facial recognition among pop stars
B.introduce tire advantage of facial recognition further
C.describe people’s fears over facial recognition
2.According to Paragraph 2, facial recognition technology can’t be used to ________.
A.pay to take the subway
B.pass through the school’s gates
C.invent an online payment app
3.What does the underlined word “leaked” in Paragraph 4 mean?
A.泄露 B.收集 C.拦截
4.From the passage, we know that ________.
A.some laws have been made to control the use of facial information
B.it may be risky to use the new technology according to the writer
C.many people think it necessary to collect data about their face
5.Which is the best title of the passage?
A.Your Face Is Your Best ID
B.Wide Use of Facial Recognition Technology
C.Facial Recognition - Progress and Challenge
