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.

Long long ago a man went to India and he had never been there before. When he got there, he saw a lot of fruit, but much of it was expensive because they couldn’t grow much because there was little water. Finally he saw a big basket of some very red and long fruit. And it was the cheapest in the shop.

So he went up and asked, “How much each kilo?”and the shop keeper said, “Two rupees(卢比). ”Two rupees in India was nothing. So he bought a whole kilogram of the fruit and started eating it. But after he ate some of it:oh, my god!His eyes watered, his mouth watered and burnt, and his face became red. He jumped up and down, saying, “Ah!Ah!Ah!”

But he still continued to eat the fruit!Some people who were looking at him shook their heads and said, “You’re crazy, man. Those are chilies(辣椒)!You can’t eat so many!People use them as a condiment, but only a little bit to put into food for taste. You can’t just eat them like that. ”But the silly man said, “No, I can’t stop!I paid money for them, and now I’ll eat them up. It’s my money!”

And you think that man was silly, right?We sometimes do a lot of things like that. We spend money, time or effort doing something. And even though it’s been a long time, hard experience tells us it won’t work, and we know there’s no more hope, we still continue just because we’ve put money, time, effort and love in to it. Just like the man who ate the chilies and felt so bad but couldn’t stop because he didn’t want to waste the money he’d paid.

So even if you’ve lost something, let it go and move on. That’s better than continuing to lose.

A.he hadn’t eaten it before                B.he was hungry

Cause and effect is one way to explain things that happen around us. Many things happen because something caused or influenced them to happen. Sometimes it is hard to look at a cause and find out what caused or influenced them to happen. Sometimes it is hard to look at a cause and find out what causes the effect. It may help you to start with the effect and use your reasoning(推理的) skills. Think about all the things you know that could be reasons for the effect you can see.

For example, you may see someone putting on a heavy jacket. This is the effect. To look for a cause, think to yourself, “What would take someone put on a heavy jacket?” Maybe the person is going outside into very cold weather. Maybe the person works in the penguin pen(企鹅圈养地) at Sea World. Maybe the person is going to visit an ice skating rink where the air is kept very cold. All of these things could be a cause for putting on a heavy jacket.

Now, think about a second example. The effect is a boy named Abi has to go to the head teacher’s office. What are the possible causes? Maybe he bullied(欺负) another student. Maybe he is just being picked up early. Maybe he is being given a prize!

Here is another example for you to think about its cause and effect. Cait, 13, was trying to fall asleep when her 8-year-old brother, Doug, came into her room. He looked around a bit, but seemed really out of it. Then Doug went back into the hallway and stood there looking straight up at the hall light for quite a while. Little brothers can be very strange, but this was really much too strange. Cait’s father appeared and explained that Doug was sleepwalking. What’s the cause end effect, could you tell?
