They may be just passing your office, computer bag slung (悬挂) over one shoulder. Or they may be sitting in a car outside it, causally tapping away at a laptop. They look like innocent passers-by. In fact, they are stealing your corporate secrets.

Drive-by hacking is the trendy term given to the practice of breaking into wireless computer networks from outside the buildings that house them. A recent study in the UK, sponsored by RSA Data Security, found that two-thirds of organizations with wireless networks were risking their data in this way. Security experts patrolled (巡逻) several streets in the City of London seeking evidence of wireless networks in operation.

Of 124 that they identified, 83 were sending data without encrypting(加密)them. Such data could readily be picked up by a passer-by armed only with a portable computer, a wireless modem and a few pieces of software that can be freely downloaded from the Internet.

The data could include sensitive company documents containing valuable information. Or they could be e-mail identities and passwords that could be used by hackers to log into corporate networks as if they were legal users.

Most companies using wireless networking technology do not take even the simplest of measures to protect their data. Nearly all wireless network technology comes with some basic security features that need only to be activated (激活) in order to give a minimum level of security, for example, by encrypting the data being passed over the network.

Raymon Kruck, business development manager at Check Point Software, a security technology specialist, believes this could be partly a psychological problem. People see the solid walls of their building as safeguards and forget that wireless networks can extend up to 200 meters beyond physical walls.

Companies without any security at all on their wireless networks make it ridiculously easy for hackers to break in. Switching on the security that comes with the network technology should be automatic. Then there are other basic steps a company can take, says Mr. Kruck, such as changing the passwords on the network from the default (默认) setting.

Companies can also install firewalls, which form a barrier between the internal network and the public Internet. They should also check their computer records regularly to spot any abnormal activity, which might betray the presence of a hacker.

1.According to the study sponsored by RSA Data Security, two thirds of the subjects _______.

A. had most of their company data stolen   

B. depended on wireless computer networks

C. were exposed to drive-by hacking

D. were unaware of the risk of wireless hacking

2.Which of the following is NOT considered in the study?

A. The number of computer hacking incidents.

B. The number of wireless computer networks identified.

C. The way in which data are sent and received.

D. The way in which data are hacked and stolen.

3.Most wireless network technology has_________.

A. data encryption program    

B. password security programs

C. illegal-user detection    

D. firewall

4.Raymond Kruck most probably agrees that wireless network security involves ________.

A. wireless signal administration  

B. changes in user’s awareness

C. users’ psychological health     

D. stronger physical walls

5.The passage is most likely to be seen in a __________

  A. book review    B. science fiction   C. textbook   D. computer magazine

 

1.C 2.A 3.A 4.B 5.D 【解析】 1.细节理解题。结合A recent study in the UK, sponsored by RSA Data Security, found that two-thirds of organizations with wireless networks were risking their data in this way.可知答案。此处in this way指的是drive-by hacking。 2.细节理解题。结合Of 124 that they identified可知B项在实验中提及;结合Such data could readily be picked up by a passer-by armed only with a portable computer, a wireless modem and a few pieces of software 可知C项在实验中提及;结合they could be e-mail identities and passwords that could be used by hackers to log into corporate networks as if they were legal users可知D项在实验中提及。 3.细节理解题。结合Nearly all wireless network technology comes with some basic security features that need only to be activated (激活) in order to give a minimum level of security, for example, by encrypting the data being passed over the network. (几乎所有的无线网络技术都有基本的安全功能,只需要被激活就能提供最低级别的安全性,例如,通过把数据加密)可知答案。 4.细节理解题。结合this could be partly a psychological problem可知在Raymond Kruck看来这是个心理问题,需要电脑使用者从意识上改变。 5.文章出处题。文章介绍了使用无线网络时,人们的安全意识不够,易导致信息被盗及如何防范。所以可确定答案为D。

[1]Global difference in intelligence is a sensitive topic, long filled with a large number of different opinions. But recent data has indeed shown cognitive (认知的) ability to be higher in some countries than in others. What's more, IQ scores have risen as nations develop—a phenomenon known as the "Flynn effect". Many causes have been put forward for both the intelligence difference and the Flynn effect, including education, income, and even non-agricultural labor. Now, a new study from researchers at the University of New Mexico offers another interesting theory: intelligence may be linked to infectious-disease rates.

  [2]The brain, say author Christopher Eppig and his colleagues, is the "most costly organ in the human body". Brainpower consumes almost up to 90 percent of a newborn's energy. It's clear that if something affects energy intake while the brain is growing, the impact could be long and serious. And for vast parts of the globe, the biggest threat to a child's body—and therefore brain—is parasitic (由寄生虫引起的) infection. These illnesses threaten brain development________________. They can directly attack live tissue, which the body must then try every means to replace. They can invade the digestive pipe and block nutritional intake. They can rob the body's cells for their own reproduction. And then there's the energy channeled (输送) to the immune system to fight the infection.

  [3]Using data on national "disease burdens" (life years lost due to infectious diseases) and average intelligence scores, the authors found they are closely associated. The countries with the lowest average IQ scores have the highest disease burdens without exception. On the contrary, nations with low disease burdens top the IQ list.

  [4]If the study holds water, it could be revolutionary for our understanding of the still-confusing variation in national intelligence scores.

After too long on the Net, even a phone call can be a shock. My boyfriend’s Liverpudlian accent suddenly becomes too difficult to understand after his clear words on screen; a secretary’s tone seems more rejecting than I’d imagined it would be. Time itself becomes fluid—hours become minutes, and alternately seconds stretch into days. Weekends, once a highlight of my week, are now just two ordinary days.

For the last three years, since I stopped working as a producer for Charlie Rose, I have done much of my work as a tele-commuter. I submit(提交) articles and edit them by E-mail and communicate with colleagues on Internet mailing lists. My boyfriend lives in England; so much of our relationship is computer-mediated.

If I desired, I could stay inside for weeks without wanting anything. I can order food, and manage my money, love and work. In fact, at times I have spent as long as three weeks alone at home, going out only to get mail and buy newspapers and groceries. I watched most of the blizzard(暴风雪) of ’96 on TV.

But after a while, life itself begins to feel unreal. I start to feel as though I’ve merged(融合) with my machines, taking data in, spitting them back out, just another node(波节) on the Net. Others on line report the same symptoms. We start to strongly dislike the outside forms of socializing. It’s like attending an A. A. meeting in a bar with everyone holding a half-sipped drink. We have become the Net opponents’ worst nightmare.

What first seemed like a luxury, crawling from bed to computer, not worrying about hair, and clothes and face, has become an avoidance(逃避),a lack of discipline. And once you start replacing real human contact with cyber interaction, coming back out of the cave can be quite difficult.

At times, I turn on the television and just leave it to chatter in the background, something that I’d never done previously. The voices of the programs relax me, but then I’m jarred by the commercials. I find myself sucked in by soap operas, or needing to keep up with the latest news and the weather. “Dateline”, “Frontline” , “Nightline,” CNN, every possible angle of every story over and over and over, even when they are of no possible use to me. Work moves from foreground to background.

1.Compared to the clear words of her boyfriend on screen, his accent becomes______.

A. unreal       B. unbearable

C. misleading       D. not understandable

2.The passage implies that the author and her boyfriend live in______.

A. the same city                  B. the same country

C. different countries              D. different cities in England

3.What does the last paragraph mean?

A. Having worked on the computer for too long, she became a bit strange.

B. Sometimes TV programs give her comfort and even makes her forget her work.

C. She watches TV a lot in order to keep up with the latest news and the weather.

D. She turns on TV now and then in order to get some valuable information.

4.What is the author’s attitude to the computer?

A. At first she likes it but later becomes tired of it.

B. She likes it because it is very convenient.

C. She dislikes it because TV is more attractive.

D. She likes it because it provides an imaginary world.

5.The underlined phrase “coming back out of the cave” probably means______.

A. going back to the dreaming world

B. coming back home from the outside world

C. bringing back direct human contact

D. getting away from living a strange life

Why do men die earlier than women? The latest research makes it known that the reason could be that men’s hearts go into rapid decline(下降) when they reach middle age.

The largest study of the effects of ageing on the heart has found that women’s longevity may be linked to the fact that their hearts do not lose their pumping power with age.

“We have found that the power of the male heart falls by 20-25 percent between 18 and 70 years of age,” said the head of the study, David Goldspink of Liverpool John Moores University in the UK.

“Within the heart there are millions of cells that enable it to beat. Between the age of 20 and 70, one-third of those cells die and are not replaced in men,” said Goldspink. “This is part of the ageing process.”

What surprises scientists is that the female heart sees very little loss of these cells. A healthy 70-year-old woman’s heart could perform almost as well as a 20-year-old one’s. “This gender( 性别) difference might just explain why women live longer than men,” said Goldspink. They studied more than 250 healthy men and women between the ages of 18 and 80, focusing on healthy persons to remove the confusing influence of disease. “The team has yet to find why ageing takes a greater loss on the male heart,” said Goldspink.

The good news is that men can improve the health of their heart with regular exercise. Goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age.

1.The underlined word “longevity” in the second paragraph probably refers to “________”.

A. health          B. ageing         C. long life            D. effect

2.The text mainly talks about ________.

A. men’s heart cells                 B. women’s ageing process

C. the gender difference              D. hearts and long life

3.According to the text, the UK scientists have known that ________.

A. women have more cells than men when they are born

B. women can replace the cells that enable the heart to beat

C. the female heart loses few of the cells with age

D. women never lose their pumping power with age

4.If you want to live longer, you should ________.

A. exercise regularly to keep your heart healthy      

B. find out the reason for ageing

C. enable your heart to beat much faster

D. prevent your cells from being lost

5.We can know from the passage that ________.

A. the reason why ageing takes a greater loss on the male heart has been found out

B. scientists are on the way to finding out why the male heart loses more of the cells

C. the team has done something to prevent the male from suffering the greater loss

D. women over 70 could lose more heart cells than those at the age of 20

(NEW YORK) A French tourist highly praised for rescuing a two-year-old girl in Manhattan said he didn’t think twice before diving into the freezing East River.

   Tuesday’s Daily News said 29-year-old Julien Duret from France was the man who left the spot quickly after the rescue last Saturday.

   He lifted the little girl out of the water after she fell off the bank at the South Street Seaport museum. He handed the girl to her father, David Anderson, who had dived in after him.

   “I didn’t think at all,” Duret told the Daily News. “It happened very fast. I reacted very fast.”

   Duret, an engineer on vacation, was walking with his girlfriend along the pier(码头) when he saw something falling into the water. He thought it was a doll, but realized it was a child when he approached the river. Immediately, he took off his coat and jumped into the water.

   When he reached the girl, she appeared lifeless, he said. Fortunately, when she was out of the water, she opened her eyes.

   Anderson said his daughter slipped off the bank when he was adjusting his camera. An ambulance came later for her, said Duret, who was handed dry clothes from onlookers. Duret caught a taxi with his girlfriend shortly after.

   The rescue happened on the day before he left for France. Duret said he didn’t realize his story of heroism had greatly moved New York until he was leaving the city the next morning.

   “I don’t really think I’m a hero,” said Duret. “Anyone would do the same thing.”

1.Why was Duret in New York?

   A. To meet his girlfriend.          B. To spend his holiday.

   C. To work as an engineer.           D. To visit the Andersons.
