19．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 25worst 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．
Top 10worst passwords：1．password 2.123456 3.12345678 4．qwerty 5．abc123
6．monkey 7.1234567 8．letmein 9．trustno1 10．dragon

14．

FIFTEEN YEAR-OLD Liu Xuyang said he has more than 30 pairs of shoes．But some are old．He doesn't want them any more．
Where should these old shoes go？To the garbage or to be recycled？
This is bow Liu began to care about old shoes．He shared his thoughts with his classmates at Beijing No.35 Middle School，Luo Hao and Yang Mengwei．The three then decided to do some research．They found out that old shoes can pollute the environment if not recycled properly．Earlier this month，their research paper won second prize in the Beijing Youth Science and Invention Competition．
The three first spent two weeks designing a questionnaire on how people deal with old shoes and how the shoes are treated．They gave over 100 questionnaires to the public，to shoemakers，garbage stations and recycling stations．
Doing the survey，they found that on average（平均），a family throws away 5.17 pairs of shoes each year．That means millions of old shoes are thrown away a year around the country．
However，most old shoes are not treated properly，according to the students．
"Usually．the old shoes are just burnt or buried（填埋）with other garbage，"said Luo．
Most of the shoes are made of chemical materials．If they are burnt or buried，they can give off gas（气）or other things that pollute the air and rivers，said the students．
They suggest there should be big boxes in cities for people to put old shoes in．The shoes could then be taken to recycling stations to be treated．
On the other hand，the shoemakers，said the students，could use more environment-friendly material to make shoes．

4．What is the first thing you want to do when you see someone yawn（打哈欠）？You want to yawn，too!Yawning is contagious．
Scientists have found that all people yawn．Babies start to yawn even before they are horn．The earliest yawn takes place when a baby is still inside its mother．When young children are about one year old，they start to yawn when they see others yawning．That's why scientists seem to think yawning is contagious．
It's no secret that yawning is contagious，but why do we yawn？Well，scientists are not really sure．
Some think we yawn because we feel bored．Recently scientists studied two groups of students between the ages of 17and 19．One group watched music videos，and the other watched a boring color test．Scientists compared the numbers of their yawns and found that the color test group yawned more times than the video group．
Another reason about yawning has to do with breathing．Some scientists believe that when we are bored or tired，we breathe more slowly．As our breathing slows down，we cannot get rid of（去除） enough carbon dioxide （CO₂） in our bodies．When there is too much carbon dioxide，our bodies will tell the brains （大脑） to breathe deeply．The result is a big yawn．
In 2007，scientists suggested a new reason．They said that the reason people yawned was to cool down their brains．These scientists found that people who were warmer than others yawned more often．
Scientists are still trying to find out why yawning happens and why it is so contagious．But they are only sure that when one person yawns，almost everyone else nearby wants to yawn，too．

52．The underlined word"contagious"in Paragraph 1 meansB．
A．helpful to our health                    B．passing from one person to another
C．hard to understand                     D．getting into one trouble after another

A．born                          B．one year old
C.17or 19years old                      D．inside their mothers
54．Which of the following are the possible reasons about yawning according to the passage？D
①People yawn because they are bored．②People yawn to catch others'attention．
③People yawn to cool down their brains．④People yawn to get rid of carbon dioxide．
a．①②③B．②③④C．①②④D．①③④

A．story book                               B．travel guidebook
C．movie poster                              D．science magazine．

11．The Little ants is a special shadow puppetry performing troupe（皮影戏演出团）．Its members'average（平均的） height（身高） is 1.28 metres．Li Ming created The Little Ants in 2009．He said he started the troupe to help little people like himself who had difficulty finding other jobs．
Li's team now has about twenty members．Like most of the members，Yang Suxuan found about The Little Ants on the internet．The village girl contacted（联系） Li Ming and decided to join the troupe，which now she calls home．
"In the past，I didn't want to communicate with others．I always felt they would laugh at me，"she recalled．"Now all my family members told me I've changed．I don't know how，but I am really glad that I found a job that can support myself．"

"My dream is to continue promoting shadow puppetry and providing more jobs to little people，"Li said．"I hope more people will understand shadow puppetry through us，and know that we little people are able to do something great too．"
