Question: Dogs are known for their sense of smell.They can find missing people and things like bombs and illegal drugs.Now a study suggests that the animal known as man's best friend can even find  bladder cancer. Cancer cells are thought to produce chemicals with unusual odors .Researchers think dogs have the ability to smell these odors, even in very small amounts, in urine .The sense of smell in dogs is thousands of times better than in humans. The study follows reports of cases where, for example, a dog showed great interest in a growth on the leg of its owner.The man was later found to be skin cancer. Carolyn Willis led a team of researchers at Amersham Hospital in England.They trained different kinds of dogs for the experiment.The study involved urine collected from bladder cancer patients, from people with other diseases and from healthy people. Each dog was tested 8 times.In each test there were 7 samples for the dogs to smell.The dog should signal the one from a bladder cancer patient by lying down next to it.Two cocker dogs were correct 56 percent of the time.But the scientists reported an average success rate of 41 percent. The British Medical Journal published the research.In all, 36 bladder cancer patients and 108 other people took part.During training, all the dogs reportedly even identified a cancer in a person who had tested healthy before the study.Doctors found a growth on the person's right kidney . Carolyn Willis says dogs could help scientists identify the combined chemicals produced by bladder cancer.That information could then be used to develop machines to test for the chemicals.The team also plans to use dogs to help identify markers for other kinds of cancer. What's the general idea of the text? A) Dogs have a good sense of smell B) Dogs can help cure cancer C) Dogs can smell cancer D) Dogs help perform experiments

Hacking our senses to boost learning power Some schools are pumping music, noises and pleasant smells into the classroom to see if it improves exam results. Could it work? Why do songs stick in our heads? What does your school smell like? Is it noisy or peaceful? It might not seem important, but a growing body of research suggests that smells and sounds can have an impact on learning, performance and creativity. Indeed, some head teachers have recently taken to broadcasting noises and pumping smells into their schools to see whether it can boost grades. Is there anything in it? And if so, what are the implications for the way we work and study? There is certainly some well-established research to suggest that some noises can have a harmful effect on learning. Numerous studies over the past 15 years have found that children attending schools under the flight paths of large airports fall behind in their exam results. Bridget Shield, a professor of acoustics   at London South Bank University, and Julie Dockrell, from the Institute of Education, have been conducting studies on the effects of all sorts of noises, such as traffic and sirens  , as well as noise generated by the children themselves. When they recreated those particular sounds in an experimental setting while children completed various learning tasks, they found a significant negative effect on exam scores. "Everything points to a bad impact of the noise on children's performance, in numeracy, in literacy, and in spelling," says Shield. The noise seemed to have an especially harmful effect on children with special needs. Whether background sounds are beneficial or not seems to depend on what kind of noise it is -- and the volume. In a series of studies published last year, Ravi Mehta from the College of Business at Illinois and his colleagues tested people's creativity while exposed to a soundtrack made up of background noises -- such as coffee-shop chatter and construction-site drilling -- at different volumes. They found that people were more... What does the conclusion of the studies of noise conducted by Bridget Shield and Julie Dockrell suggest? A) Peaceful music plays an active role in students' learning. B) Not all noises have a negative impact on children's performance. C) We should create for school children a more peaceful environment. D) Children with special needs might be exposed to some particular sounds.
