The Theory of Everyone
If Stephen Hawking lives until the year 2017, he will have lived more than 50 years longer than his doctors expected. When he was a college student, doctors discovered that he had a rare disease. This disease causes a gradual disintegration(分解)of the nerve cells in the brain cells that regulate voluntary muscle activity. Death almost always occurs within two or three years.
Today Stephen Hawking cannot walk or speak. He cannot move his arms or his head. He cannot taste or smell anything. And yet this man is Professor of Mathematics at Cambridge University, a position held by the famous scientist Isaac Newton in 1669.
Hawking is often described as the greatest scientist since Albert Einstein, but to the world outside science, he is also known as the man who made scientific theory understandable. His book, A Brief History of Time, has sold over eight million copies.
He says that since he does not have to think about his body or do any of the things other men have to worry about, such as washing the car or working in the yard, he can dedicate all of his time to thinking. This puts him in the perfect position to find the answer to the question that he has dedicated his life to. His question is: Is there a complete theory of the universe and everything in it?
Despite his tremendous physical disabilities, he has already made some very important discoveries about the origin of the universe, how the universe holds together, and how it will probably end. He has also been able to explain the secrets of “black holes” in space. Now he is looking for a set of rules that everything in our universe must obey. He calls it the Theory of Everything. He thinks that someone will have found the answer within the next 20 years.
If Stephen Hawking is able to find his Theory of Everything, he will have given the world the opportunity to understand things that will change the whole nature of science and probably also the way we live.

Learning DisabilitiesLearning disabilities are very common.They affect perhaps 1 0 percent of all children.Four times as many boys as girls have learning disabilities.Since about 1970,new research has helped brain scientists understand these problems better.Scientists now know there are many different kinds of learning disabilities and that they are caused by many different things.There is no longer any question that all learning disabilities result from differences in the way the brain is organized.You cannot look at a child and tell if he or she has a learning disability.There is no outward sign of the disorder.So some researchers began looking at the brain itself to learn what might be wrong.In one study,researchers examined the brain of a learning-disabled person who had died in an accident. They found two unusual things.One involved cells in the left side of the brain,which control language.These cells normally are white.In the learning disabled person,however,these cells were gray.The researchers also found that many of the nerve cells were not in a line the way they should have been.The nerve cells were mixed together.The study was carried out under the guidance of Norman Geschwind,an early expert on learning disabilities, Doctor Geschwind proposed that learning disabilities resulted mainly from problems in the left side of the brain. He believed this side of the brain failed to develop normally.Probably,he said,nerve cells there did not connect as they should.So the brain was like an electrical device in which the wires were crossed.Other researchers did not examine brain tissue.Instead,they measured the brain's electrical activity and made a map of the electrical signals.Frank Dully experimented with this technique at Children's Hospital Medical Center in Boston.Doctor Dully found large differences in the brain activity of normal children and those with reading problems.The differences appeared throughout the brain.Doctor Dully said his research is evidence that disabilities involve damage to a wide area of the brain,not just the left side.Which of the following is NOT mentioned in the passage?A:Learning disabilities may result from the unknown area of the brain.B:Learning disabilities may result from damage to a wide area of the brain.C:Learning disabilities may result from abnormal organization of the brain cells.D:Learning disabilities may result from problems in the left side of the brain.

Sleep Lets Brain File MemoriesTo sleep.Perchance to file?Findings published online this week by the Proceedings of the National Academy of Science further support the theory that brain organizes and stows memories formed during the day while the rest of the body is catching zzz's.Gyorgy Buzsaki of Rutgers University and his colleagues analyzed the brain waves of sleeping rats and mice.Specifically,they examined the electrical activity emanating from the somatosensory neocortex(an area that processes sensory information)and the hippocampus,which is a center for learning and memory.The scientists found that oscillations in brain waves from the two regions appear to be intertwined.So-called sleep spindles(bursts of activity from the neocortex)were followed tens of milliseconds later by beats in the hippocampus known as ripples.The team posits that this interplay between the two brain regions is a key step in memory consolidation.A second study,also published online this week by the Proceedings of the National Academy of Sciences,links age-associated memory decline to high glucose level.Previous research had shown that individuals with diabetes suffer from increased memory problems.In the new work,Antonio Convit of New York University School of Medicine and his collaborators studied 30 people whose average age was 69 to investigate whether sugar levels,which tend to increase with age,affect memory in healthy people as well.The scientists administered recall tests,brain scans and glucose tolerance tests,which measure how quickly sugar is absorbed from the blood by the body's issues.Subjects with the poorest memory recollection,the team discovered,also displayed the poorest glucose tolerance.In addition, their brain scans showed more hippocampus shrinkage than those of subjects better able to absorb blood sugar."Our study suggests that this impairment may contribute to the memory deficits that occur as people age,"Convit says."And it raises the intriguing possibility that improving glucose tolerance could reverse some age一associated problems in cognition?”Exercise and weights control can help keep glucose level in check,so there may be one more reason to go to the gym.Which of the following statements is the nearest in meaning to the sentence"To sleep.Perchance to file?"A:Does brain arrange memories in useful order during sleep?B:Does brain have memories when one is sleeping?C:Does brain remember files after one falls asleep?D:Does brain work on files in sleep?
