Typing your password or credit card number into a computer is a moment’s work. But if you think your personal details disappear as soon as you hit the Return key, think again: they can sit on the computer’s hard disk for years waiting for a hacker to rip them off.
As people spend more time on the web and hackers become more sophisticated, the dangers of storing personal information on computers are growing by the day, security experts say. There are some safeguards, such as never allowing your computer to store your passwords. But even that is no guarantee of security.
When you type in a password, it is stored in random access memory (RAM), where it is held temporarily until other data overwrites it or the computer is switched off.
But every so often, the computer copies the contents of its RAM onto hard disk, where it is easy prey for a hacker, who can read it directly or design a worm to e-mail it back. The longer sensitive data stays in RAM, the more likely it is to be copied onto the disk, where it stays until it is overwritten—which might not happen for years.
Tal Garfinkel and colleagues from Stanford University have created a software tool which simulates the workings of a complete computer system. Within the simulation, sensitive data can be tagged and then tracked as it passes through the system. Next, Garfinkel and his team simulated computers running common software that regularly handles passwords or confidential personal information, such as Internet Explorer, the Windows login script and Apache server software.
In a paper to be presented, they conclude that the programs took virtually no measures to limit the length of time the information is retained. Some of the tested software even copied the sensitive information, apparently without restraint.
This is the first time anyone has tried to measure the extent of this problem, says Rebecca Wright, a security expert at Stevens Institute of Technology. Garfinkel hopes the results will arouse software developers to take action.

In choosing a friend, one should be very careful. A good friend can help you study. You can have fun together and make each other happy. Sometimes you will meet fair-weather friends, who will be with you as long as you have money or luck, but when you are down, they will run away. How do I know when I have found a good friend? I look for certain qualities (品质) of character, especially understanding, honesty and reliability (可靠).
Above all else, I look for understanding in a friend. A good friend tries to understand how another person is feeling. He is not quick to judge. Instead, he tries to learn from others. He puts himself in the other person’s place, and he tries to think of ways to be helpful. He is also a good listener.
At the same time, however, a good friend is honest. He does not look for faults (过错) in others. He notices their good points. In short, a friend will try to understand me and accept me.
Another quality of a friend is reliability. I can always depend on a good friend. If he tells me he will meet me somewhere at a certain time, I can be sure that he will be there. If I need a favor, he will do his best to help me. If I am in trouble, he will not run away from me.
There is a fourth quality that makes a friend special. A special friend is someone with whom we can have fun. We should enjoy our lives, and we would enjoy our friendship. That is why I especially like friends who are fun to be with. A good friend likes the same things I like. We share experience (经验) and learn from each other. A good friend has a good sense of humor, too. He likes to laugh with me. That is how we share in the joy of being friends. And I know that he is looking for the same quality in me.
When I meet someone who is reliable, honest, and understanding, I know I’ve found a friend! If you have fair-weather friends, _____.
| A．they will give you all that they have when you need help |
| B．you will be refused when you get into trouble |
| C．you will become rich |
| D．you can be sure that you get real friends |
Good friends need to ______.
| A．always point out each other’s mistakes |
| B．be helped with money |
| C．understand each other’s feelings |
| D．have money or luck. |
This passage mainly discusses ________.

| D．the importance of having a friend |
Three boys and three girls were going to Fort Lauderdale and when they boarded the bus，they were carrying sandwiches and wine in paper bags，dreaming of golden beaches as the gray cold of New York vanished behind them.
As the bus passed through New Jersey，they began to notice Vingo, He sat in front of them，dressed in a plain，ill-fitting suit，never moving，his dusty face masking his age. He kept chewing the inside of his lip a lot，frozen into some personal cocoon of silence.
Deep into the night，outside Washington，the bus pulled into Howard Johnson's，and everybody got off except Vingo. He sat rooted in his seat，and the young people began to wonder about him，trying to imagine his life：perhaps he was a sea captain，a runaway from his wife，an old soldier going home. When they went back to the bus，one of the girls sat beside him and introduced herself.
"We're going to Florida,” she said brightly, “I hear it's really beautiful.”
“It is，”he said quietly，as if remembering something he had tried to forget.
"Want some wine?" she said. He smiled and took a swig. He thanked her and once again returned to his silence. After a while，she went back to the others，and Vingo nodded in his sleep.
In the morning，they awoke outside another Howard Johnson's．And this time Vingo went in. The girl insisted that he join them. He seemed very shy, and ordered black coffee and smoked nervously as the young people chattered about sleeping on beaches. When they returned to the bus，the girl sat with Vingo again，and after a while, slowly and painfully，he told his story. He had been in jail in New York for the past four years，and now he was going home.
“Are you married?”
“I don't know.
“You don’t know?” she said.
“Well，when I was in jail I wrote to my wife，”he said. “I told her that I was going to be away a long time，and that if she couldn't stand it．if the kids kept asking questions，if it hurt too much，well she could just forget me, I'd understand. Get a new guy，I said she's a wonderful woman，really something and forget about me. I told her she didn't have to write me for nothing. And she didn't. Not for three and a half years.”
"And you’re going home now，not knowing?”
“Yeah，”he said shyly. “Well，last week，when I was sure the parole (假释) was coming through, I wrote her again. We used to live in Brunswick，just before Jacksonville，and there’s a big oak (橡树) tree just as you came into town. I told her that if she'd take me back，she should put a yellow handkerchief on the tree，and I'd get off and come home, If she didn't want me, forget it, no handkerchief，and I'd go on through.”
"Vow,” the girl exclaimed. "Wow.”
She told the others，and noon all of them were in it, caught up in the approach of Brunswick，looking at the pictures Vingo showed them of his wife and three children. The woman was handsome in a plain way，the children still unformed in the much-handled snapshots.
Now they were 20 miles from Brunswick, and the young people took over window seat on the right side，waiting for the approach of the great oak tree. The bus acquired a dark，hushed mood，full of the silence of absence and lost years. Vingo stopped looking, tightening his face into the ex-con's mask, as if fortifying himself against still another disappointment.
Then Brunswick was ten miles, and then five. Then，suddenly，all of the young people were up out of their seats，screaming and shouting and crying，doing small dances of joy. All except Vingo.
Vingo sat there stunned，looking at the oak tree. It was covered with yellow handkerchiefs，20 of them，30 of them，maybe hundreds，a tree that stood like a banner of welcome billowing in the wind. As the young people shouted，the old rose and made his way to the front of the bus to go home.Which is right about Vingo?
| A．He was a sea captain. |
| B．He was a runaway from his wife, |
| C．He was an old soldier going home. |
