The second unintended use of information from social networking websites is employers who check on prospective employees. A June 11, 2006 New York Times article reported that many companies use search engines and social networking websites such as MySpace, Xanga, and Facebook to conduct background checks on college campuses. Although the use of MySpace or Google to check a student’s background is somewhat unsettling to many undergraduates, the Times noted that the use of Facebook is especially shocking to students who believe that Facebook is limited to current students and recent alum(校友).
Corporate employers are not the only people interested in college students’ lives. The third unintended use of social networking websites is college administrators who monitor the Internet — especially Facebook — for student bad behavior. For example, a college in Boston’s Back Bay expelled (除名) its student Government Association President for joining a Facebook group highly critical of a campus police sergeant. In addition, fifteen students at a state university in North Carolina faced charges in court for underage drinking because of photos that appeared on Facebook.
Although more users of websites such as Facebook are becoming aware of the potential dangers of online identities, many regular users still fail to take there basic security precautions(警惕). First, only make your information available to a specific list of individuals whom you approve. Second , regularly search for potentially harmful information about yourself that may have been posted by mistake or by a disgruntled
(不满的)former associate. Thrid, never post obviously offensive material will likely make its way to the wider world. By taking these simple steps, members of the digital world can realize the many benefits of e-community without experiencing some of the damaging unintended consequences.

This is a finding of Norman R. Pace and his team at the University of Colorado, in the US. The scientists investigated bacteria in all kinds of human environment, including showers．Pace"s team looked at 45 showerheads in nine American cities. They discovered that 30 percent of them had large amounts of flying Mycobacterium.
But Pace said that they pose few threats to the health．Only those with a weak immune system might need to worry．He told the New York Times that the bacteria are not as unpleasant as might be thought．He said that having a shower is no more dangerous than anything else we do in the morning．
But for those who feel sick about the idea of all those microorganisms (微生物), he had some advice. Let the water run for 30 seconds before getting into the shower. Why? The number of bacteria is smaller than that when the water is just turned on. If that seems like a waste of water, he added that you could also change your showerhead every few months.
However, Pace had good news too. He has also been testing the air in US subways. Apart from iron particles (粒子), which are ground off the track by the wheels of trains, subway air is fresh. The reason is that a train’s movement pumps fresh outdoor air into the tunnels.
Pace explained that he wanted to understand the natural microbial environments of public places. This kind of knowledge might help discover the microbes to be used in a bioterrorist (生物恐怖分子) attack.
小题1:From the finding of Norman R. Pace, after taking a shower, we might cough or feel tired because .
| A．it’s easy to get a cold when taking a bath |
| B．the showerhead carries many bacteria causing illness |
| C．we don’t get cleaned while showering |
| D．we don’t get a weak immune system |
| A．Hot water could kill most of bacteria in showerheads. |
| B．Of 45 showerheads surveyed in nine cities, 30 carried large amounts of Mycobacterium. |
| C．Changing showerheads is the only way to avoid microorganisms. |
| D．Shower water contains much less bacteria after being left to run for 30 seconds. |
| A．having a shower in the morning is more dangerous than at other time |
| B．the bacteria always threat people’s health |
| C．there is no reason to fear microorganisms for people with strong immune system |
| D．it is better to do some exercise in the morning than have a shower |
| A．cause | B．avoid | C．describe | D．promise |
| A．The train’s movement. | B．Iron particles． |

The earliest evidence for human–cat interaction dates back to prehistoric Cyprus（史前塞浦路斯）, where the remains of a wild cat and a human — dated 9,500 years old — were found buried together.
A new study in the Proceedings of the National Academy of Sciences has confirmed the first direct evidence of a human–domestic cat relationship among Chinese farmers 5,300 years ago. Researchers studied the bones of cats, dogs, deer and other animals unearthed in an excavation (挖掘) near a village in Central China. By using some ways, scientists showed that the cats were living on a mostly millet(黍)–based diet, just like the domesticated dogs and pigs from the site.
"The most reasonable explanation for a high consumption of millet–based food is that the cats had formed a stable and mutual relationship with humans and could easily feed on rodents (啮齿动物) around human villages, find leftover food or even have been fed by people intentionally," said Hu Yaowu from the Chinese Academy of Sciences in Beijing, whose research focuses on the relationship between humans and domesticated animals.
"It is very interesting for us to find the consumption of millet-based foods by the cats, since this kind of evidence had long been missing.” Hu explains. Since cats usually eat meat, such a diet would be unexpected, unless the cats were being fed by people, the study argues. The researchers also found that one of the cats survived to reach old age, implying that it had a safe place to live and enough to eat.
Why the farmers wanted to keep cats nearby or make them "pets" could be answered by other evidence. Chinese archaeologists found some storage containers were specifically designed to keep out rodents — a vermin (害兽) that cats could certainly have helped with.
The simplified theory is that rats were attracted to the food of farmers, and so were harmful to farmers. Cats were attracted to the rats, and so farmers formed a mutually beneficial relationship with cats, taking care of them in return for pest control.
小题1:The evidence found in the remains dating back to prehistoric Cyprus means .
| A．human made cats pets as early as 9,500 years ago |
| B．human interacted with cats very early |
| C．cats didn’t appear until prehistoric Cyprus |
| D．when cats became domesticated |
| A．the preventions of pests from grains |
| B．the history of Chinese farming |
| C．the dogs and pigs |
| D．the ways to keep pets |
| A．Cats didn’t feed on meat. |
| B．The cats consumed large amounts of millet–based foods. |
| C．One of the cats survived to reach old age. |
| D．Some storage containers were specifically designed to keep out rodents. |
| A．Helping keep other domesticated animals. |
| B．Not letting cats eat food. |
| C．Supplying meat for human. |
| D．Helping reduce the amount of pests. |
| A．Entertainment | B．Environment |
| C．Human and Science | D．Life and fashion |
Get a high school diploma, at least. Without that, you will be occupationally dead unless your name happens to be George Bernard Shaw or Thomas Alva Edison, and you can successfully dropout in grade school.
Get a college degree, if possible. With a B. A., you are on the launching pad. But now you have to start to put on the brakes. If you go for a master’s degree, make sure it is an M.B.A., and the famous law of diminishing(逐渐减少的) returns begins to take effect.
Do you know, for instance, that long-haul truck drivers earn more per year than full professors? Yes, the average salary for those truckers was $24000 while the full professors managed to earn just $23030.
A doctorate is the highest degree you can get. Except for a few specialized fields such as physics or chemistry where the degree can quickly be turned to industrial or commercial purposes, if you pursue such a degree in any other field, you will face a future which is not bright. There are more doctors unemployed or underemployed in this country than any other part of the world.
If you become a doctor in English or history or anthropology or political science or languages or—worst of all—in philosophy, you run the risk of becoming overeducated for our national demands. Not for our needs, mind you, but for our demands.
Thousands of doctors are selling shoes, driving cars, waiting on table, and endlessly filling out applications month after month. They may also take a job in some high school or backwater(闭塞) college that pays much less than the doorkeeper earns.
You can equate the level of income with the level of education only so far. Far enough, that is, to make you useful to the gross national product, but not so far that nobody can turn much of a profit on you.
小题1:According to the writer, what the society expects of education is to turn out people who ______.
| A．will not be a disgrace to society |
| B．will become loyal citizens |
| C．can take care of themselves |
| D．can meet the nation’s demand as a source of manpower |
| A．they are improperly educated |
| B．they are of little commercial value to their society |
| C．there are fewer jobs in high schools |
| D．they prefer easier jobs that make more money |
| A．with diplomas |
| B．who specialize in physics and chemistry |
| C．who are valuable to the gross national product |
| D．who receive little education |
| A．Bernard Shaw didn’t finish high school, nor did Edison. |
| B．One must think carefully before pursuing a master’s degree. |
| C．The higher your education level, the more money you will earn. |
| D．If you are too well-educated, you’ll be overeducated for society’s demands. |
| A．a means of providing job security and financial security and a means of meeting a country’s demands for technical workers |
| B．a way to broaden one’s horizons |
| C．more important than finding a job |
| D．an opportunity that everyone should have |
Here are some very important—and often ignored—guidelines to taking a test successfully.
Do not insist on completing each question before going to the next. This is extremely important. Remember one question may only be worth one point! You will become nervous when you fail to find out its answer, making you lose your concentration and leading to worse results. However, answering the questions you are sure you know results in your being more relaxed and feeling more confident.
Go through the test a second time working out the answers to more difficult questions. Sometimes questions asked are answered in later questions asking for different things.
Usually(but not always) a strong first impulse(冲动) means we know the answer and we don’t really have to think about it too much. Going back to think about it usually makes you unsure and often causes a mistake. This is very common, so be very careful!
If you don’t know the answer, write something. If you are answering a 4 possibility multiple choice question you will still have a 25% chance of being correct!
Taking a test is as much for you as is for your teacher, so never cheat. If you cheat, you don’t help yourself in the long run.
小题1:In the first paragraph, the writer stresses the importance of ______.
| A．better preparations for exams. |
| B．better understanding of English. |
| C．better skills at taking exams. |
| D．better results of taking exams. |
| A．to first answer the questions which are easier to you. |
| B．to depend on your first impulse to answer the questions. |
| C．to search the test paper for all the answers to the questions. |
| D．to give up the questions whose answers you don’t know. |
| A．pay much attention to their testing skills. |
| B．often give up a difficult test halfway. |
| C．often get higher results by cheating. |
| D．don’t believe in their first impulse. |
| A．Effective Studying Methods. | B．Effective Test Taking Skills. |
| C．Getting Better Exam Results. | D．Being Successful Students. |
It seems both Parisians and tourists are taking advantage of the program．Since its launch a little over two weeks ago，Vélib has already seen almost half a million rentals．And，with the addition of 10，000 more bikes and 700 more stations in the next 12 months，city officials expect at least 200，000 regular users by year end．
Parisian Olivier Bioret has already gone for a spin on one of Vélib’s vehicles and plans to make use of them more often．
“It’s a real pleasure—when，like me，you don’t have space enough in your flat to have your
own bike—to be able to discover．to cross Paris and not have to take the subway，”he said．
As a socialist and longtime green activist，Mayor Bertrand Delanoe regards Vélib as just a part of his plan to reduce car traffic and，thus，lower pollution by 2020．
Apart from its environmental benefits，Vélib is also being praised as a way of collecting money for the city，for all the money from rentals goes to the city government．
Paris is not alone in its attempt to profit from the power of the bicycles．
Across the globe，cities such as Barcelona，which stated its bike-share program in March with 1,500 vehicles and 100 stations，and New York，which launched a five-day trial program last month，are using bicycles as a way to cut back on both traffic and pollution．
However，it remains to be seen whether people’s acceptance of these programs is simply a
passing fashion or whether this movement has the power to take root and transform the face of public transportation around the world．
小题1:The real purpose of Vélib is________．
| A．to help people save money and space |
| B．to make some money for the city government |
| C．to provide convenience to both Parisians and tourists |
| D．to reduce traffic and pollution in the city |
| A．There will be 700 stations in one year’s time． |
| B．There will be over 20, 000 bikes in use in a year． |
| C．In the first two weeks there were nearly a million rentals． |
| D．There will be 200, 000 regular rentals each day by year end． |
| A．other cities also have such programs |
| B．Parisians can use the bicycles free of charge |
| C．Paris sets an example to many other cities |
| D．Paris is the first city to start such a program |
| A．critical | B．optimistic | C．uncertain | D．negative |
