They may be just passing your office, computer bag slung (懸掛) 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 (巡邏) 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 (默認(rèn)) 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.
小題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

In the animal kingdom, weakness can bring about aggression in other animals. This sometimes happens with humans also. But I have found that my weakness brings out the kindness in people. I see it every day when people hold doors for me, pour cream into my coffee, or help me to put on my coat. And I have discovered that it makes them happy.
From my wheelchair experience, I see the best in people, but sometimes I feel sad because those who appear independent miss the kindness I see daily. They don’t get to see this soft side of others. Often, we try every way possible to avoid showing our weakness, which includes a lot of pretending. But only when we stop pretending we’ re brave or strong do we allow people to show the kindness that’ s in them.
Last month, when I was driving home on a busy highway, I began to feel unwell and drove more slowly than usual. People behind me began to get impatient and angry, with some speeding up alongside me, horning (按喇叭) or even shouting at me. At that moment,I decided to do something I had never done in twenty-four years of driving. I put on the car flashlights and drove on at a really low speed.
No more angry shouts and no more horns!
When I put on my flashlights, I was saying to the other drivers, “I have a problem here. I am weak and doing the best I can.” And everyone understood. Several times, I saw drivers who wanted to pass. They couldn’t get around me because of the stream of passing traffic. But instead of getting impatient and angry, they waited, knowing the driver in front of them was in some way weak.
Sometimes situations call for us to act strong and brave even when we don’t feel that way. But those are few and far between. More often, it would be better if we don’t pretend we feel strong when we feel weak or pretend that we're brave when we’re scared.
小題1:The author has discovered that people will feel happy when ________.
A.they offer their help
B.they receive others’ help
C.they feel others’ kindness
D.they show their weakness
小題2:The author feels sad sometimes because ________.
A.he has a soft heart
B.he relies much on others
C.some people pretend to be kind
D.some people fail to see the kindness in others
小題3:What did the other drivers do when they saw the flashlights?
A.They speeded up to pass.
B.They waited with patience.
C.They tried their best to help.
D.They put on their flashlights too.
小題4:In this passage, the author advises us to ________.
A.handle problems by ourselves
B.a(chǎn)ccept help from others
C.a(chǎn)dmit our weakness
D.show our bravery

The Pacific island nation of Nauru used to be a beautiful place.Now it is an ecological disaster area.Nauru’s heartbreaking story could have one good consequence — other countries might learn from its mistakes.
For thousands of years, Polynesian people lived in the remote island of Nauru, far from western civilization.The first European to arrive was John Fearn in 1798.He was the British captain of the Hunter, a whaling ship.He called the island Pleasant Island.
However, because it was very remote, Nauru had little communication with Europeans at first.The whaling ships and other traders began to visit, bringing guns and alcohol.These elements destroyed the social balance of the twelve family groups on the island.A ten-year civil war started, which reduced the population from 1,400 to 900.
Nauru’s real troubles began in 1899 when a British mining company discovered phosphate (磷酸鹽)on the island.In fact, it found that the island of Nauru was nearly all phosphate, which was a very important fertilizer for farming.The company began mining the phosphate.
A phosphate mine is not a hole in the ground; it is a strip mine.When a company strip-mines, it removes the top layer of soil.Then it takes away the material it wants.Strip mining totally destroys the land.Gradually, the lovely island of Nauru started to look like the moon.
In 1968, Nauru became one of the richest countries in the world.Every year the government received millions and millions of dollars for its phosphate.
Unfortunately, the leaders invested the money unwisely and lost millions of dollars.In addition, they used millions more dollars for personal expenses.Soon people realized that they had a terrible problem — their phosphate was running out.Ninety percent of their island was destroyed and they had nothing.By 2000, Nauru was financially ruined.Experts say that it would take approximately $433,600,000 and more than 20 years to repair the island.This will probably never happen.
小題1:What might be the author’s purpose in writing the text?
A.To seek help for Nauru’s problems.

C.To show the importance of money
D.To give a warning to other countries
小題2:What was Nauru like before the Europeans came?
A.Rich and powerful B.Peaceful and attractive

The cheetah(獵豹)is best known for being the world’s fastest land animal, reaching speeds of just over 110kph for short period of time. However, many people know little else about this wonderful animal. The word cheetah probably comes from a Hindi word spotted animal. It is very similar to other cats but also has some obvious differences. Its body is much leaner than most cats and it has much longer legs.
People sometimes make a cheetah a leopard(美洲豹)because they both have spots, but in fact they are very different. A leopard is far heavier and more powerful, but also much slower. The cheetah’s spots cover most of its body except for its stomach and throat. The cheetah’s tail has spots and these become rings at the end of the tail.
An adult cheetah weighs between 35-65 kilograms and is about 80 centimeters high at the shoulder. The cheetah’s head is quite small and the eyes are quite high up. A black line runs from each eye down to its mouth and makes it look a little sad. It has high shoulders that help it to walk so gracefully.
Cheetahs are very fast but they are not very strong. They are not good fighters and will run away rather than fight another animal to protect their food. If they make a kill, it is sometimes taken away from them by stronger animals such as lions and leopard. These animals will kill their young if they get the chance. The cheetah is not a threat to humans at all. It will not attack humans and prefers to stay away from occupied areas.
小題1:Many people know that the cheetah________
A.is a fast runner
B.runs faster than any other animal on land
C.runs as fast as it can
D.is very fast for periods of time
小題2:The cheetah ________
A.has spots all over its body including its tail
B.has spots on its stomach and throat
C.does not have spots on its stomach and throat
D.has spots everywhere except for its stomach and throat
小題3:Cheetahs will not fight another animal to protect their food because _______
A.they can quickly run away
B.they are very fast runners
C.They want to protect their young
D.They are poor fighters

Kuss Middle School serves students in Fall River, Mass. , a former mill town that has struggled economically for decades. Students at Kuss have struggled, too, usually falling short of making the academic progress required under the No Child Left Behind law.
Then, last year, the school experimented with extending the school day. Teachers got paid at a higher hourly rate.
Students weren't thrilled at first with leaving school at 4:15 p.m. instead of at 2:20 p.m. But the added hours gave them more time for physical education and let them select special interest classes. By the end of the year, student scores had risen by enough to enable Kuss to make the progress required under the federal No Child Left Behind law.
The only surprise is that more districts haven't lengthened school schedules set decades ago to accommodate (適應(yīng)) a farm economy rather the information economy of today.
School days
The USA ranks 36th of 40 industrialized nations in average weekly instructional time.
Selected countries:
1) Thailand--30.5 hours  2) Korea--30.3 hours  7) China--26.5 hours
14) France--24.6 hours  15 ) UK--24.6 hours
16) Mexico--24.2 hours  23 ) Japan--23.8 hours
26)Canada--23.6 hours  36)USA--22.2 hours  40)Brazil--19 hours
New research suggests the time is ready for a change:
Matched against 39 other developed countries, the United States is near the bottom in the rankings of average weekly instructional time in school.  Measured over 12 years, students in the top-scoring countries spend the equivalent of a full extra year in school.
US students perform poorly on math and science tests compared to their international peers, according to a US Education Department comparison released earlier this month. In math, American 15-year-old scored near the bottom among the study's 30 developed countries.
Most countries that boost the number of minutes spent on math instruction find pay offs in improved math scores, according to a study released this month by the Brookings Institution. Small in creases in the school day are more effective than a longer school year, the report concluded.
The most encouraging news about the benefits of extending the school day comes from Massachusetts, where an experiment with 10 schools, including Kuss, appears to be working. Those 10 schools lengthened their instructional days by 25% and boosted their state scores in math, English and science at all grades.
Perhaps the concept won't work everywhere. Certainly, it won't instantly be popular. But it's obvious that a problem exists or that adding class time seems to help.
小題1:What is the main idea of the above passage?
A.Experiments with extended school hours produce academic gains.
B.Kuss Middle School sets a good example for US education.
C.Academic progress has achieved under the No Child Left Behind law.
D.Information age calls for more instructional lime at all schools.
小題2:A longer school day is suggested for the following reasons except that _________.
A.students from many developed countries spend more time at school
B.American students do a bad job at science subjects
C.teachers are paid at a higher rate with time added
D.a(chǎn) longer school day works better than a longer school year
小題3:Which statement is true of Kuss Middle School?
A.Kuss Middle School lies in where a farm economy is changing to an information one.
B.Kuss Middle school has joined the federal "No Child Left Behind" progrann
C.Neither teachers nor students are happy with the longer school day.
D.Adding class time functions at Kuss Middle School.

A.a(chǎn) positive attitude towards adding school time
B.a(chǎn) negative attitude towards adding school time
C.a(chǎn) changing attitude towards adding school time
D.a(chǎn) right attitude towards adding school time

In 2006, the UK government started to allow universities in England and Wales to charge British students tuition fees. More than 80 percent of students in England and Wales now take out a student loan in order to go to university. They use the loan (貸款)  to pay for tuition fees, books and living expenses. Although the interest on student loans is quite low, it begins as soon as the student receives the loan. The average student in England and Wales now graduates from university with debts of around £12,000. Students of medicine usually have debts of more than £20,000. That is a lot of money. It means graduates cannot afford to buy a house for many years. They even struggle to pay rent on a flat, because they have to start paying back the student loan after graduating. If you start to earn over £15,000 a year, the government takes repayments directly from your monthly salary. Is it any surprise, therefore, that the average British person does not leave their parents’ home until they are 30 years old?
You might think that a British person with a degree will find it easy to get a well-paid job. However, most people in white-collar jobs seem to have a degree these days, so there is a lot of competition. Also, British companies tend to value work experience over a piece of paper. Like everyone else, graduates usually have to start at the bottom and work their way up. That can be very frustrating for them, since they are often over-qualified for the work they are doing. While at university, they have dreams of getting an exciting, challenging job. Therefore, life after university ends up being quite disappointing for a lot of graduates.
All of the above is beginning to make British people question whether a university degree is really worth the money.
小題1:What's the best title of this passage?
A.What's a University Education worth in the UK?
B.There is a lot of competition in the UK

A.University Education is really worth the money in England
B.University Education is worth all over the world except in England
C.British education is becoming more expensive for a majority of British students
D.British students don't like to go to university
小題3:We can infer from the passage ____
A.The average British person didn't leave their parents' home until they are
35 years old
B.Having a degree doesn't get aBritish person a good job
C.Students are graduating without larger and larger debts.

Let children learn to judge their own work. A child learning to talk does not learn by being corrected all the time; if corrected too much, he will stop talking. He notices a thousand times a day the difference between the language he uses and the language those around him use. Bit by bit, he makes the necessary changes to make his language like other people’s. In the same way, children learn to do all the other things without being taught to walk, run, climb, whistle, ride a bicycle…They compare their own performances with those of more skilled people, and slowly make the needed changes. But in school we never give a child a chance to find out his mistakes and correct them for himself. We do it all for him. We act as if we thought that he would never notice a mistake. If it is a matter in mathematics or science, give him the answer book. Let him correct his own papers. Why should we teachers waste time in such routine(日常的) work? Our job should be to help the child when he tells us that he can’t find the way to get the right answer. Let the children learn what all educated persons must some day learn, how to measure their own understanding, how to know what he does not know.
小題1:According to the passage, the best way for children to learn things is by_____.

Have you ever heard of blogs (博客)? If you haven’t, you should have. It’s here, it’s growing and it’s having an influence on our life. Surf the Internet and you’ll find blogs everywhere. A blog, shortened from “weblog”, is a public Internet journal written by one person or a group of people. It is a website in which a person or a group can place news, personal thoughts, text, photos, video or audio files, or links upon which visitors can comment. A blog lets you post on the Internet without having to know web design or be technical. You are given an environment to make dated entries on the topic of your choice which are “published”, so other people can read them.
Authoring a blog, maintaining a blog or adding an article to an existing blog is called “blogging”. Blogging has revolutionized Internet publishing in the last several years because it gives everyone with Internet access the opportunity to become an online writer.
