Despite all the reports of Internet security attacks over the years, including the recent ones on Google’s e-mail service, many people have reacted to the break-ins with a shrug(耸肩).
Mr. Shulman and his company examined a list of 32 million passwords that an unknown hacker stole last month from RockYou, a company that makes software for users of social networking sites like Facebook and MySpace. The list was briefly posted on the Web, and hackers and security researchers downloaded it.
The list provided an unusually detailed window into computer users’ password habits. Typically, only government agencies like the F.B.I. or the National Security Agency have had access to such a large password list.
Some Web sites try to keep back the attackers by freezing an account for a certain period of time if too many incorrect passwords are typed. But experts say that the hackers simply learn to trick the system, by making guesses at an acceptable rate, for instance.
To improve security, some Web sites are forcing users to mix letters, numbers and even symbols in their passwords. Others, like Twitter, prevent people from picking common passwords.
Still, researchers say, social networking and entertainment Web sites often try to make life simpler for their users and are reluctant to put too many controls in place.
Even commercial sites like eBay must weigh the consequences of freezing accounts, since a hacker could, say, try to win an auction(拍卖) by freezing the accounts of other potential buyers.
But owing to the reality of our overcrowded brains, the experts suggest that everyone choose at least two different passwords — a complex one for Web sites where security is vital, such as banks and e-mail, and a simpler one for less risky places, such as social networking and entertainment sites.
Mr. Moss relies on passwords at least 12 characters long, figuring that those make him a more difficult target than the millions of people who choose five- and six-character passwords.
“It’s like the joke where the hikers run into a bear in the forest, and the hiker that survives is the one who outruns his companions,” Mr. Moss said. “You just want to run that bit faster.

Two years after the First World War (1914-1918), a small group of soldiers left the army and returned to their hometown in France. Most of them lived well, but one of them was poor. His name was Clinton. Once a year they had supper in Barton’s house. Barton was very rich.
One evening Barton showed his friends a large gold coin at the supper table. The coin was passed around and praised by everyone. At the same time they were talking and talking. They soon forgot about the coin. After supper, Barton asked for his coin, but nobody could tell where it was. It was lost. One man said that everyone must be searched.

查看习题详情和答案>>The big Town Hall clock was striking midnight when Frank began to cross the bridge. The dark night air was cold and slightly wet, and the street lamp gave little light.
Frank was anxious to get home and his footsteps rang loudly on the pavement(人行道). When he reached the middle of the bridge he thought he could hear someone coming near behind him. He looked back but could see no one. However, the sound continued and Frank began to walk more quickly. Then he slowed down again, feeling shame at having acted so foolishly. There was nothing to fear in a town as quiet as this.
Just then, he heard short, quick steps closely behind him. By the time he reached the other side of the bridge, he could almost feel someone at his heels(脚后跟). He turned round and there stood a man in a large overcoat. A hat pulled down over his eyes and very little of his face could be seen. Frank said something about the weather, trying to sound friendly and calm. The man did not answer but asked rudely where Oakfield House was. Frank pointed to a big house in the distance and the stranger continued his way.
Then Frank wondered why the stranger had wanted to find Oakfield House at such an hour.
He knew that the people who lived there were very rich. Almost without realizing what he was doing, he began following the stranger quickly. Then the man was soon outside the house and Frank saw him look up at the window. A light was still on and the man waited until it went out. When about half an hour had passed, Frank saw him climb noiselessly over the wall and heard him drop on the ground at the other side.
Now Frank realized what was going to happen. He walked quickly and silently across the street towards a telephone box on the comer.
