The Intelligent Transport team at Newcastle University have turned an electric car into a mobile laboratory named “DriveLAB” in order to understand the challenges faced by older drivers and to discover where the key stress points are.
Research shows that giving up driving is one of the key reasons for a fall in health and well-being among older people, leading to them becoming more isolated(隔绝) and inactive.
Led by Professor Phil Blythe, the Newcastle team are developing in-vehicle technologies for older drivers which they hope could help them to continue driving into later life.
These include custom-made navigation(导航) tools, night vision systems and intelligent speed adaptations. Phil Blythe explains: “For many older people, particularly those living alone or in the country, driving is important for preserving their independence, giving them the freedom to get out and about without having to rely on others.”
“But we all have to accept that as we get older our reactions slow down and this often results in people avoiding any potentially challenging driving conditions and losing confidence in their driving skills. The result is that people stop driving before they really need to.” Dr Amy Guo, the leading researcher on the older driver study, explains, “The DriveLAB is helping us to understand what the key points and difficulties are for older drivers and how we might use technology to address these problems.
“For example, most of us would expect older drivers always go slower than everyone else but surprisingly, we found that in 30mph zones they struggled to keep at a constant speed and so were more likely to break the speed limit and be at risk of getting fined. We’re looking at the benefits of systems which control their speed as a way of preventing that.
“We hope that our work will help with technological solutions(解决方案) to ensure that older drivers stay safer behind the wheel.”
1.What is the purpose of the DriveLAB?
A. To explore new means of transport. B. To design new types of cars.

An international team of researchers from the University of Oxford have found that the way people use the Internet is closely tied to the seasonal movements in the natural world. Their online species searches follow the patterns of seasonal animal migrations (迁徙).
Migratory birds ( 候 鸟 ) flood back to where they reproduce every spring. That migratory behavior is accompanied by some human behavior. “In English-language Wikipedia ( 维基百科), the online searches for migratory species tend to increase in spring when those birds arrive in the United States,” said the lead author John Mittermeier.
And not just birds. Mittermeier and his team surveyed nearly 2.5 billion Wikipedia search records, for 32,000 species, across 245 languages. They also saw variable search rates for insects, horsetails and flowering plants. Seasonal trends seemed to be widespread in Wikipedia behavior for many species of plants and animals.
This finding suggests new ways to monitor changes in the world’s biological diversity. It also shows new ways to see how much people care about nature, and which species and areas might be the most effective targets for conservation.
Mittermeier is encouraged by the search results. He commented, “I think there’s a concern among conservationists (生态环境保护者) that people are losing touch with the natural world and that they’re not interacting with native species anymore. And so in that sense, it was really exciting and quite unexpected for me to see people’s Wikipedia interest closely related to changes in nature.” Richard Grenyer, Associate Professor from the University of Oxford, says search data is useful to conservation biologists, “By using these big data approaches, we can direct our attention towards the difficult questions in modern conservation: which species and areas are changing, and where are the people who care the most and can do the most to help.”
1.What have researchers found about species searches?
A.They strengthen ties among people. B.They affect the animal movements.
C.They reflect animal migration seasons. D.They differ in language backgrounds.
2.What is the purpose of writing Paragraph 3?
A.To further support the research findings.
B.To show the variety of species searches.
C.To summarize the research process.
D.To present researchers’ heavy work load.
3.How does Mittermeier feel about the search results?
A.Sad about people’s not getting close to nature.
B.Worried about Wikipedia behavior.
C.Amazed at people’s care about nature.
D.Satisfied with Wikipedia’s service.
4.From which is the text probably taken?
A.A scientific magazine. B.A biology textbook.
C.A biography. D.A travel brochure .

Researchers from the University of Newcastle are leading a worldfirst study which builds on earlier unpublished research that children are most likely to be guided by their father's eating and exercise habits.
The new study “Healthy Dads,Healthy Kids”,led by Associate Professor Philip Morgan from the University's Faculty of Education and Arts,is designed to help fathers promote and demonstrate to their children positive behaviors related to physical activity and healthy eating.
“The earlier findings showed that children are more likely to follow the example set by their father than their mother when it comes to eating and exercise,”said Morgan.Morgan saw striking results in a previous trial involving 165 overweight children.He found children who lost the most weight had fathers who were engaged in the new eating and exercise plan.
“We might think mothers are the main influence on children's diet and health,but the reality may be different,”said Morgan.“The roles of fathers are changing.More families have two parents working and more fathers are involved with food preparation and food shopping than in the past.”
“Fathers influence the food and physical activity habits in the home through their behaviours,attitudes and approach to food and eating,and act as a role model to their children,”said Morgan.
Researchers are inviting fathers who would like to reduce their weight to join the “Healthy Dads,Healthy Kids” program.Participation involves attending eight sessions (讲习班) at the University of Newcastle over six months where the men will receive information,have weightrelated measurements recorded and complete questionnaires.
Cooking healthy food with the kids and creating a backyard fitness circuit (循环训练场) are among the assignments (课外作业) for fathers taking part in the study.
1.What do we learn about the “Healthy Dads,Healthy Kids” program?
A.It aims to build close family relationships.
B.It involves fathers who want to lose weight.
C.It will last more than eight months.
D.It offers free online courses for parents.
2.Morgan finds a link between children's weight loss and .
A.their parents' efforts
B.their father's influence
C.balanced diets
D.regular sports training
3.Which of the following facts causes the change of fathers' roles?
A.That kids have more time to spend with family.
B.That more kids need their father's help in learning.
C.That there are more working mothers than before.
D.That fathers become much busier than before.

Researchers in the psychology department at the University of California at Los Angeles(UCLA) have discovered a major difference in the way men and women respond to stress. This difference may explain why men are more likely to suffer from stress-related disorders.
Until now, psychological research has maintained that both men and women have the same “fight-or-flight” reaction to stress. In other words, individuals either react with aggressive behavior, such as verbal or physical conflict(“fight”), or they react by withdrawing from the stressful situation(“flight”). However, the UCLA research team found that men and women have quite different biological and behavioral responses to stress. While men often react to stress in the fight-or-flight response, women often have another kind of reaction which could be called “tend and befriend.” That is, they often react to stressful conditions by protecting and nurturing their young(“tend”), and by looking for social contact and support from others—especially other females (“befriend”).
Scientists have long known that in the fight-or-flight reaction to stress, an important role is played by certain hormones(激素) released by the body. The UCLA research team suggests that the female tend-or-befriend response is also based on a hormone. This hormone, called oxytocin, has been studied in the context of childbirth, but now it is being studied for its role in the response of both men and women to stress. The principal investigator, Dr. Shelley E. Taylor, explained that “animals and people with high levels of oxytocin are calmer, more relaxed, more social, and less anxious.” While men also secrete(分泌) oxytocin, its effects are reduced by male hormones.
In terms of everyday behavior, the UCLA study found that women are far more likely than men to seek social contact when they are feeling stressed. They may phone relatives or friends, or ask directions if they are lost.
The study also showed how fathers and mothers responded differently when they came home to their family after a stressful day at work. The typical father wanted to be left alone to enjoy some peace and quiet. For a typical mother, coping with a bad day at work meant focusing her attention on her children and their needs.
The differences in responding to stress may explain the fact that women have lower frequency of stress-related disorders such as high blood pressure or aggressive behavior. The tend-and-befriend regulatory(调节的) system may protect women against stress, and this may explain why women on average live longer than men.
1.Which of the following is true about oxytocin according to the passage?
A. Men have the same level of oxytocin as women do.
B. Oxytocin used to be studied in both men and women.
C. Both animals and people have high levels of oxytocin.

2.What can be learned from the passage?
A. Male hormones help build up the body’s resistances to stress.
B. In a family a mother cares more about children than a father does.
C. Biological differences lead to different behavioral responses to stress.
D. The UCLA study was designed to confirm previous research findings.
3.Which of the following might be the best title of the passage?
A. How men and women suffer from stress
B. How men and women get over stress
C. How researchers overcome stress problems
D. How researchers handle stress-related disorder

Think for a moment about the teachers you have had at school or at university. Which one did you like best? And Why? Were the teachers you liked best also the ones who were the best teachers, in you opinion? Before you read any further, consider for a minute the qualities that make a teacher outstanding(出色).
Some very common answers to this question are that teachers need to love their students, that they need to have an expert knowledge of their subjects, and that they should devote themselves completely to their jobs. All of these ideas are, of course, true to a certain extent(程度)but they are perhaps a little too simple.
It is impossible for anyone to love everyone they know, and teachers deal with a very large number of students over the years. On the other hand, teachers should certainly be able to make their students feel that they are interested in them as people and in the development of both their characters. A deep knowledge on to the students effectively-a teacher needs to be trained in the skills of teaching. These skills include how to control a class, and so on. Finally, teachers have to devote a lot of time and energy to their work, of course. However, they are also models that their students must follow; so it is important that they should be well-balanced people with interests outside their school work-family, friends, hobbies, etc. A teacher who only lives for work is likely to become too narrow-minded.
1. The author suggests that you think about the teachers you have had at school or at university so that_______
A. you might praise outstanding teachers
B. you might know the qualities of outstanding teachers
C. you might select outstanding teachers
D. you might learn from outstanding teachers
2. The author does not consider it possible for a teacher_______
A. to love all the students he has taught or is teaching
B. to have a good knowledge of the subject he teaches
C. to pass the knowledge of his subjects on to his students effectively
D. to be an example for his students to follow
3. A well - balanced person is one_______.
A. who devotes all his time and energy to his work
B. who devotes most of his time and energy to his family, friend, hobbies, etc
C. who has interests both in and outside his work
D. who has interests neither in nor outside his work
4. From the passage, we can conclude that_______.
A. most teachers are born with such skills as how to explain a lesson clearly
B. it is not necessary of teachers to spend much time and energy on their work if they do have an expert knowledge of their subjects
C. teachers should be trained to love all the students they are teaching or have taught
D. even if a teacher has a good knowledge of his subjects, he can not be a good teacher if he doesn’t have the ability to pass that knowledge on to his students.

Researchers at the University of Bedforshire have developed a new technique for powering electronic device(装置). The system, developed by Professor Ben Allen at the Centre for Wireless Research, uses radio waves as power.
Believed to be a world first, the team claims it could eventually eliminate (or get rid of) the need for conventional batteries. The university has now filed a patent application to secure the only rights to the technique.
Professor Allen and his team have created a system to use medium wave frequencies to replace batteries in small everyday devices like clocks and remote controls.
The new technique uses the “waste” energy of radio waves and has been developed as part of the university’s research into “power harvesting”. Professor Allen said that as radio waves have energy---like light waves, sound waves or wind waves---in theory, these waves could be used to create power.
“The emerging(新兴的)area of power harvesting technology promises to reduce our reliance on conventional batteries,” he said. “It’s really exciting way of taking power from sources other than what we would normally think of.”
The team is now waiting for the results of the patent application to secure recognition of the technique. Professor Allen said that the team’s achievements had all been done in their “spare time”. “Our next stage is to try and raise some real funds so that we can take this work forward and make a working prototype(模型)and maybe partner up with the right people and take this to a full product in due course,” he said.
“Power harvesting has a really important part in our future, because, just in this country, we dispose of somewhere between 20,000 and 30,000 tones of batteries in landfill(垃圾填理)sites every single year-that is toxic chemicals going into the ground.”
He added that development of the product could also be “commercially beneficial”. “The market for this is several billion pounds. We’ve seen market predictions for 2020 which have these kinds of figures, so there’s a lot of commercial potential in this area,” he said.
Pro-Vice Chancellor at the University of Bedfordshire, Professor Carsten Maple, said, “This type of work is a reflection of the university’s growing reputation and experience in conducting innovative(创新的)research.”

Scientists, psychologists and English academics at Liverpool University have found that reading the works of the classical writers like Shakespeare and Wordsworth has a great effect on the mind, catches the reader’s attention and triggers moments of self-examination.
Using a special machine, they monitored the brain activity of 30 volunteers as they read works by William Shakespeare, William Wordsworth, T.S. Eliot and others.
In the first part of the research, the brain activity of 30 volunteers was monitored as they read passages from Shakespeare’s plays, including King Lear, Othello, Coriolanus and Macbeth, and again as they read the text rewritten in a simpler form or modern language.
While reading the common texts, normal levels of electrical activity were shown in their brains. When they read the works of Shakespeare, however, the levels of activity jumped because of his use of words which were unfamiliar to them. The result of the test showed that the more challenging passages cause a greater degree of electrical activity in the brain than the common ones.
Scientists went on to study the brain activity as it responded to each word and recorded how it lit up as the readers came across unusual words, surprising phrases or difficult sentences in the classical works. As a result, this lightening up process of the mind lasted longer than that when volunteers read common texts, encouraging further reading.
The research also found that reading poetry especially increases activity in the right hemisphere(半球) of the brain, an area connected with “autobiographical memory”, driving the readers to think carefully about their own experiences based on what they have read. The academics said this meant the classical works of literature are more useful than self-help books.
Philip Davis, an English professor who has worked on the study in the university’s magnetic resonance center, announced this week: “Classical literature acts like a rocket-booster(火箭加速器) to the brain, which provides extra power for the brain. You may never imagine how powerful it is. The research shows such kind of literature can create new thoughts and connections in the young and the old.”
1.The underlined word “trigger” in Paragraph 1 is closest in meaning to “______”.
A.depends on B.picks up
C.sets off D.changes into
2.Which of the following is NOT true about reading classical literature?
A.It makes readers’ brain more active than reading common texts.
B.It makes readers’ electrical activity of brain return to normal.
C.It’s helpful for readers to come up with new ideas.
D.It’s an activity that is suitable for people of all ages.
3.From the research, we can learn that ______.
A.the readers prefer Shakespeare’s works to the other writers’ works
B.the words of classical works make it hard for volunteers to read further
C.reading classical works produces a good and long-lasting effect on the mind
D.poetry increases left-brain activity more than other literary forms
4.What does the author mainly tell us in this passage?
A.Shakespeare’s plays deserve to be read.
B.Common books are unpopular anymore.
C.Poetry is best for developing people’s brain.
D.Classical works help the brain develop better.

Scientists at the University of Oxford have developed new artificial intelligence software to recognize the faces of chimpanzees in the wild. The new software will allow researchers to significantly cut back on time and resources spent analyzing video footage.
“For species like chimpanzees, which have complex social lives and live for many years, recording their behavior from short-term field research can only tell us so much.” says Dan Schofield, researcher and DPhil student at Oxford University’s Primate Models Lab. “By using the power of machine learning to unlock large video footage, it makes it feasible to measure behavior over the long term. Observing how the social lives of a group change over several generations become possible as well.”
The computer model was trained using over 10 million images from Kyoto University’s Primate Research Institute (PRI) video footage of wild chimpanzees in West Africa. The new software is the first to recognize individuals in a wide range of poses, performing with high accuracy in difficult conditions such as low lighting, poor image quality and movement blur (模糊).
“Access to this large video footage has allowed us to use cutting edge deep neural networks to train models at a scale that was previously not possible.” says Arsha Nagrani, co-author of the study and DPhil student in University of Oxford. “Additionally, our method differs from previous primate face recognition software in that it can be applied to raw video footage with limited manual intervention (人工干预) or pre-processing, saving hours of time and resources.”
The technology has potential for many uses, such as monitoring species for protection. Although the current application focused on chimpanzees, the software provided could be applied to other species, and help drive the adoption of artificial intelligence systems to solve a range of problems in the wildlife sciences.
“All our software is available open-source for the research community.” says Nagrani. “We hope that this will help researchers across other parts of the world apply the same cutting-edge techniques to their unique animal data sets. As a computer vision researcher, it is extremely satisfying to see these methods applied to solve real, challenging biodiversity (生物多样性) problems.”
“With an increasing biodiversity crisis and many of the world’s ecosystems under threat, the ability to closely monitor different species and populations using systems will be important for protection efforts, as well as animal behavior research.” adds Schofield. “Interdisciplinary cooperation like this have huge potential to make an impact, by finding solutions for old problems, and asking biological questions which were previously not available on a large scale.”
1.What’s the function of the new artificial intelligence software?
A.Analyzing video footage in difficult conditions.
B.Recognizing the faces of chimpanzees in the wild.
C.Cutting edge deep neural networks to train models at a scale.
D.Saving hours of time and resources without manual intervention.
2.What does the underlined word “feasible” in Paragraph 2 probably mean?
A.possible B.important
C.natural D.official
3.From the passage, we know that the artificial intelligence software could ________.
A.recognize individuals but not clearly
B.save time and resources only
C.help to protect different species
D.hardly solve biodiversity problems
4.What is the main purpose of the passage?
A.To introduce a new software.
B.To explain a measure.
