Soon Tommy’s parents, who had recently separated (分居), would arrive for a meeting on his failing schoolwork and  【小题1】  behavior. Neither parent knew that I had called up   【小题2】 . 
Tommy, an only child, had   【小题3】 been happy, cooperative, and an excellent student. How could I make his father and mother  【小题4】  that his recent failing grades   【小题5】  a brokenhearted child’s reaction to his respected parents’ separation and possible   【小题6】 ?
Tommy’s mother came in and   【小题7】 one of the chairs I had placed near my desk. Then the father   【小题8】  and was surprised to see his wife. They pointedly ignored each other.
As I gave a detailed   【小题9】 of Tommy’s behavior and schoolwork, I prayed for the   【小题10】  words to bring these two together to help them see what they were doing to their son.   【小题11】  somehow the words wouldn’t come.
I found a crumpled (弄皱的), tear-stained  【小题12】  in the back of Tommy’s desk. Writing covered both sides, a single  【小题13】  scribbled (乱写) over and over.
Silently I smoothed it out and gave it to Tommy’s mother. She read it and then without a word   【小题14】 it to her husband. He frowned. Then his face softened. He studied the scribbled words for  【小题15】  seemed a future life.
At last he folded the paper carefully and   【小题16】 his wife’s hand. She wiped the tears from her  【小题17】 and smiled up at him. I also couldn’t keep back tears, but  【小题18】 seemed to notice.
In this way I used the words to  【小题19】  that family. On the sheet of yellow copy paper   【小题20】  with the painful outpouring of a small boy’s troubled heart, it said, “Dear Mother; Dear Daddy; I love you. I love you. I love you.”

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（黑客） stole last month from Rock You, 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 Wed sites are forcing users to mix letters,numbers 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 unwilling 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.”

The underlined sentence “Many people have reacted to the break-ins with a shrug” shows that many people            .

A.don’t take seriously the hacker’s break-ins

B.are worried and frightened at the hacker’s break-ins

C.don’t know what to do with the hacker’s attacks

D.are eager to get helps from the experts

Which would be the best title for the passage?

A.Password, good luck or risk!                          B.Popular Passwords, High Risk!
