Students who work during term time to support themselves at university are far more likely to graduate with a poor degree, according to a government-funded study published yesterday.
Undergraduates with part-time jobs are a third less likely to get a first or upper second-class degree than other students, harming their career chances. Students from the poorest backgrounds were most likely to take jobs during term because they could not depend on help from their parents.
The report, commissioned (委托) by the Department for Education and Skills, also found a clear relation between fear of debt and employment in non-graduate jobs. Students from poorer backgrounds are known to be more unwilling to be in debt than those from middle class families.
The study of 8,600 people who graduated in 1999 was made by Peter Elias, of Warwick University, and Kate Purcell, from Bristol Business School. They found that twice as many first-class degrees were awarded to students who did not work during term compared with those who did. Between 35 and 38 percent who worked during term achieved a lower second, compared with about 28 percent of those who did not.
Professor Elias said that the increase in school fees next year to ￡3,000 would have to be monitored (监控) carefully for its effect on poorer students. "Higher education is going to be a harder struggle for those who do not come with all the advantages," he said.
He suggested that universities could get in touch with employers to provide work experience on good salaries to choose students during holidays, so that they did not have to work during term.What's the main idea of the passage?

Most of the people who appear most often and most gloriously in the history books are great conquerors and generals and soldiers, whereas the people who really helped civilization forward are often never mentioned at all. We do not know who first set a broken leg, or launched a seaworthy boat, or calculated the length of the year, or manured(施肥)a field; but we know all about the killers and destroyers. People think a great deal of them, so much so that on all the highest pillars (纪念柱) in the great cities of the world you will find the figure of a conqueror or a general or a soldier. And I think most people believe that the greatest countries are those that have beaten in battle the greatest number of other countries and ruled over them as conquerors. It is just possible they are, but they are not the most civilized.
Animals fight; so do savages (野蛮人); hence to be good at fighting is to be good in the way in which an animal or a savage is good, but it is not to be civilized. Even being good at getting other people to fight for you and telling them how to do it most efficiently －this, after all, is what conquerors and generals have done －is not being civilized. People fight to settle quarrels. Fighting means killing, and civilized peoples ought to be able to find some way of settling their disputes other than by seeing which side can kill off the greater number of the other side, and then saying that that side which has killed most has won. And it not only has won, but, because it has won, has been in the right. For that is what going to war means; it means saying that might is right.
That is what the story of mankind has on the whole been like. Even our own age has fought the two greatest wars in history, in which millions of people were killed or disabled. And while today it is true that people do not fight and kill each other in the streets －while, that is to say, we have got to the stage of keeping the rules and behaving properly to each other in daily life － nations and countries have not learnt to do this yet, and still behave like savages.In the opening sentence the author indicates that ________.

In the author’s opinion, the countries that ruled over a large number of other countries are
| A．certainly both the greatest and the most civilized |
| B．neither the most influential nor the most civilized. |

Scientists have long puzzled over how iguanas, a group of lizards(蜥蜴) mostly found in the Americas, came to live in the isolated Pacific islands of Fiji and Tonga. Some scientists used to suppose that they must have traveled there on a raft, a journey of around 5,000 miles from South America to the islands. There are documented cases of iguanas reaching remote Caribbean islands and the Galapagos Islands on floating logs. But new research in January by Brice Noonan and Jack Sites suggested that iguanas may have simply walked to Fiji and Tonga when the islands were still a part of an ancient southern supercontinent.
The ancient supercontinent was made up of present-day Africa, Australia, Antarctica and parts of Asia. If that’s the case, the island species would need to be very old. Using “molecular (分子) clock” analysis of living iguanas’ DNA, Noonan and Sites found that, sure enough, the lineage of iguanas has been around for more than 60 million years—easily old enough to have been in the area when the islands were still connected by land bridges to Asia or Australia.
Fossils (化石) uncovered in Mongolia suggest that iguanid ancestors did once live in Asia. Though there’s currently no fossil evidence of iguanas in Australia, that doesn’t necessarily mean they were never there. “The fossil record of this continent is surprisingly poor and cannot be taken as evidence of true absence,” the authors write.
So if the iguanas simply walked to Fiji and Tonga from Asia or possibly Australia, why are they not also found on the rest of the Pacific islands? Noonan and Sites say fossil evidence suggests that iguana species did once inhabit other islands, but went extinct right around the time when humans settled in those islands. But Fiji and Tonga have a much shorter history of human presence, which may have helped the iguanas living there to escape extinction.
The researchers say that their study can’t completely rule out the rafting theory, but it does make the land bridge theory “far more reasonable than previously thought.” What did some scientists previously believe about the iguanas?
| A．They were once discovered in America. |
| B．They traveled by raft to Fiji and Tonga. |
| C．They could survive in poor living conditions. |
| D．They moved to Fiji and Tonga from Australia. |
According to Noonan and Sites, 60 million years ago ____.

Sometime in the next century, the familiar early-newspaper on the front porch (门廊) will disappear. And instead of reading your newspaper, it will read to you. You'll get up and turn on the computer newspaper just like switching on the TV An electronic voice will distribute stories about the latest events, guided by a program that selects the type of news you want. You'll even get to choose the kind of voice you want to hear. Want more information on this brief story? A simple touch makes the entire text appear. Save it in your own personal computer if you like. These are among the predictions from communication experts working on the newspapers of the future. Pictured as part of broader home-based media and entertainment systems, computer newspapers will unite print and broadcast reporting, and offer news and analysis with video images of news events.
Most of the technology is available now, but convincing more people that they don't need to read a newspaper is the next step. But resistance to computer newspapers may be stronger from within journalism. Since it is such a cultural change, it may be that the present generation of journalists and publishers will have to die off before the next generation realizes that the newspaper industry is no longer a newspaper industry. Technology is making the end of ' traditional newspapers unavoidable.
Despite technological advances, it could take decades to replace newsprint with computer screens. It might take 30 t0 40 years to complete the changeover because people need to buy computers and because newspapers have established financial interests in the paper industry. Which of the following is NOT an advantage of computer newspapers?
| A．They are cheaper than traditional newspapers. |
| B．They are more convenient to read. |
| C．You can choose the kind of voice you want to hear. |
| D．You can easily save information for future use. |
Which of the following is a reason why it will take a long time to complete the changeover?
| A．The technology is impossible now. |
| B． Computer newspaper s are too expensive. |
| C．The popularization of computers needs a long time. |
| D．Traditional newspapers are easier to read. |
It can be inferred that journalists are against computer newspapers because _______ .
| A．they don't know how to use computers |
| B．they think computer newspapers take too much time to read |
| C．they think the new technology is bad |
| D．they have been trained to write For traditional newspapers |
We can infer from the passage that
| A．all technological changes are good |
| B．new technologies don't always replace old ones |
| C．new technologies will eventually replace old ones |
| D．traditional newspapers are here to stay for another century |
What is the best title of the passage?
| A．Computer newspapers are well liked. |
| B．Newspapers of the future will be on the computer. |
| C．Newspapers are out of fashion. |
| D．New communications technology. |
Losing weight comes with a lot of health benefits—including making your brain sharper.
Yes, it turns out that overweight may damage cognitive functions (认知功能) such as memory and attention. There have been few studies of overweight and cognitive functioning, possibly because it is generally believed that it is not a primary risk cause for poor cognitive performance. Losing weight, therefore, may help improve these mental functions, according to a new research led by John Gunstad, assistant professor of psychology at Kent State University.
Growing evidence suggests that being fat is linked to cognitive deficits (缺陷). So Gunstad and his team guessed that losing weight might improve mental function. For their study, they measured memory and attention in a group of 150 overweight participants, some of whom had some kind of operation for weight loss and some did not. All of the volunteers completed mental skills tests to assess their abilities of memory and attention at the beginning of the study, and again 12 weeks later. To begin with, about 24% of the patients showed damaged learning and 23% showed signs of poor memory when tested. At the end of the study, those who had lost weight after operation improved their scores into the average or above average range for cognitive functions. Scores for the volunteers who didn’t lose weight dropped even further.
The study helped Gunstad to find out whether losing weight had any effect on mental function. Now that he’s seen the positive effect that weight loss can have on memory and attention, he says he will next study those who choose to lose weight by the traditional way—eating healthier and getting more active. He expects that losing weight in this way will have a similarly positive effect on the brain. “If we can improve the condition with operations, then we can probably produce the same change with behavioral weight loss as well,” he says. There is less research on overweight and cognitive functions because researchers _____.
| A. believe overweight only affects our body |
| B. have focused on ways to sharpen people’s mind |
| C. do not consider overweight a main cause for low cognitive ability |
| D. are clear about the relation between weight and mental functions |
The result of Gunstad’s study shows that ______.
| A. losing weight has little effect on people’s memory |
| B. losing weight can improve people’s mental functions |
| C. overweight people are likely to have psychology problems |
| D. overweight people’s abilities of concentration differ greatly |
What is Gunstad planning to prove next in his research?
| A. Slim people are smarter than overweight people. |
| B. Healthy diet is better than exercise in losing weight. |
| C. Traditional ways of losing weight are better than operation. |
| D. Overweight people will get smarter by taking more exercise. |
Which of the following is the best title for the text?
| A. Body Weight and Health |
| B. Losing Weight by Operation |
| C. Ways to Improve Mental Functions |

Caffeine not only gives us a daily jump start, but new research suggests it also can strengthen long-term memory.
According to the US Food and Drug Administration, nearly 90 percent of people worldwide consume about 200 milligrams of caffeine each day. That' s equivalent to about one strong cup of coffee a day. Writing in " Nature Neuroscience" , Johns Hopkins University researchers say their findings show that caffeine strengthens certain memories for up t0 24 hours after being taken in.
" We've always known that caffeine has cognitive-enhancing effects (促智效果) , but its ,particular effects on strengthening memories and making them resistant to forgetting has never been examined in detail in humans, " said senior author of the paper Michael Yassa. " We re- port for the first time a specific effect of caffeine on reducing forgetting over 24 hours. " Conducting a double-blind trial, the researchers worked with a test group of people who didn't regularly consume caffeinated products. Five minutes after studying a series of images, the test subjects were given either a placebo(无效对照剂) or a 200-milligram caffeine tablet.
To check the caffeine levels of their test subjects, the research team took saliva samples (唾液样品) from them before they took their tablets and again one, three and 24 hours after- wards.
Both groups of test participants ( those who took the placebo and those who took the caffeine tablet) were tested the following day to see if they could recognize the images they' d seen the previous day.
The test included showing the test subjects another series of images that included some new images , those that were shown the previous day, as well as other images that were similar, but not the same as those they had viewed earlier.
The researchers found that more members of the group who were given the caffeine tablets were able to correctly identify some of the new images as " similar" to previously viewed images rather than incorrectly identifying them as the same.
"We also know that caffeine is associated with health and longevity(长寿) and may havesome protective effects from cognitive decline like Alzheimer' s disease (阿尔茨海默症). " said Yassa.The purpose of the new research is
| A．to survey how much caffeine people consume a day |
| B．to write the paper " Nature Neuroscience" |
| C．to prove caffeine has cognitive-enhancing effects |
| D．to examine caffeine ' s memory-strengthening effects in detail |
During the research ,the researchers did the following things EXCEPT
| A．giving the test subjects placebos or caffeine tablets |
| B．checking the caffeine levels of the test subjects |
| C．encouraging the test subjects to drink more coffee |
| D．showing the test subjects series of images |
How did the test subjects show the caffeine ' s memory-strengthening effects?
| A．By recognizing images they ' d seen the previous day. |
| B．By taking the caffeine tablets instead of placebos. |
| C．By identifying the new images as the same. |
| D．By telling the differences between new images. |
What will the next part of the text possibly talk about?
| A．Ways to achieve health and longevity. |
| B．The effects caffeine has on health. |
| C．The treatment for Alzheimer' s disease. |
| D．The harmful effects of cognitive decline. |
