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(聳肩).

  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(拍賣) 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.

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

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

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

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

are eager to get helps from the experts

60.   According to the passage, which of the following web sites needs a more complex password?

A social web site.

An entertainment web site.

A commercial web site.

A government web site.

61.   The Internet users are advised to______ in order to keep back the hackers.

mix letters, numbers and symbols as well

choose passwords with at least 12 characters

choose passwords with 5 or 6 characters

choose at least two different passwords

62.   Which would be the best title for the passage?

Password, Simple or Complex?

Popular Passwords, High Risk!

Clever Hackers, Stupid Netizens.

Hacker, the Enemy of Internet Security.

第三部分:閱讀理解(共20小題,每題2分,滿分40分)

閱讀下列短文,從每題所給的四個選項(A、B、C和D)中,選出最佳選項,并在答題卡上將該項涂黑。

I was helping in my son’s classroom when I spotted a poster that reads, “Sticks and stones

may break my bones but words can break my heart”. I started thinking.

Teachers are such an important part of a child’s life. A teacher’s support determines how safe a child feels in school. His inspiration determines how much risk a child will take in the classroom, his understanding determines how important a child feels in school and his love determines a child’s motivating and attitude toward education. And the effect a teacher has on a child doesn’t end when the school bell rings at the end of the day. Rather, those feelings developed in the classroom go home with the child and, in a large part, determine what sort of evening the child and the family have. The importance of a teacher to a child is fantastic and cannot be over-emphasized.

All my children are fortunate to have remarkable teachers. Consequently, the three of them love going to school almost as much as they love using teacherisms. For example, one of Hannah’s favorite phrases in used when I mess up. She looks at me with understanding and says, “It’s okay to make mistakes, mama, because you’re only learning.” Rachael’s favorite phrase is used to start most of her jobs; with a glow in her eye, she says, “I’m just going to do my best, mama, because that’s all I can do!” But perhaps my favorite is Jacob’s response to his sisters when one of them says something he doesn’t like. With his hand on his heart he says, “Don’t say that because words can break my heart.”

Like most parents, I hear teacherisms daily. And every time I hear one, my heart floods with gratefulness for the wonderful teachers who make my children feel safe, important, and successful in the classroom, and who are helping my children achieve emotional good health. There is much talk today how to measure a teacher’s worth. I think we need only look at the students. Children mirror teachers’ words and actions, and the content of those reflections shows teacher’s greatness.

51.Teachers are important to students in that________.

       A.they equip them with book knowledge

       B.they help free the parents from worries

       C.they guarantee each family a happy evening

       D.they help keep them emotionally healthy

52.The three children’s examples are used to show that________.

       A.they are lucky to have wonderful teachers

       B.they can eventually develop into good teachers

       C.they are sometimes mentally hurt by the teachers

       D.they have a successful performance in school

53.To his mother, what the boy says possibly sounds________.

       A.ridiculous B.convincing       C.humorous D.inspiring

54.The underlined word “teacherisms” probably refers to “________ ”.

       A.how teachers normally deal with their students

       B.what teachers usually say to their students

       C.why teachers seem important to their students

       D.where teachers agree with their students
