A new book claims to have definitive evidence of a long-suspected technological crime-that Alexander Graham Bell stole ideas for the telephone from a competitor, Elisha Gray. In The Telephone Gambit:Chasing Alexander Graham Bell"s Secret,journalist Seth Shulman argues that Bell-aided by aggressive lawyers and a corrupt patent examiner-got an improper glance at patent documents Gray had filed,and that Bell was incorrectly credited with filing first. Shulman believes the smoking gun is Bell"s lab notebook,which was limited by Bell"s family until 1976, then digitized and made widely available in 1999. The notebook details the false starts Bell met as he and assistant Thomas Watson tried transmitting sound electromagnetically over a wire.Then,after a 12-day gap in 1876-when Bell went to Washington to sort out patent questions about his work-he suddenly began trying another kind of voice transmitter.That method was the one that proved successful. As Bell described that new approach,he drew a diagram of a person speaking into a device.Gray"s patent documents,which described a similar technique,also featured a very similar diagram. Shulman"s book describes other elements that have angered researchers" suspicions. For instance,Bell"s transmitter design appears hastily(草率地) written in the margin of his patent; Bell was nervous about demonstrating his device with Gray present; Bell resisted testifying(作证) in an 1878 lawsuit solving this question; and Bell,as if ashamed,quickly distanced himself from the telephone patent right bearing his name. Perhaps the most instructive lesson comes when Shulman explores why historical memory has favoured Bell but not Gray-nor German inventor Philipp Reis.who beat them both with 1860s telephones that employed a different principle. One reason is simply that Bell,not Gray.actually demonstrated a phone that transmitted speech.Gray was focused instead on his era"s pressing communications challenge:how to send multiple messages simultaneously(同时地) over the same telegraph wire.As Gray shouted to his lawyers,"I should like to see Bell do that with his instruments." | ||

If you want to improve your child"s results at school, you could do a lot worse than ensuring that they do plenty of exercise.Scientists have already shown that physical activity can make you brainier.But a team in America has used scans to show that an important part of the brain actually grows in children who are fit.These youngsters tend to be more intelligent and have better memories than those who are inactive. Scientists also found that one of the most important parts of their brains was 12 percent larger than those of unfit children.They believe that encouraging children to take exercise from a very young age could help them do better at school later.Researchers from the University of Illinois, in the U.S., studied the brains of 49 children aged nine and ten using a magnetic resonance imaging scan (核磁共振 摄影扫描), a technique which provides very detailed pictures of organs and tissues in the body. They also tested the fitness levels of the children by making them run on a treadmill (跑步机).The scientists found that the hippocampus, a part of the brain responsible for memory and learning, was around 12 percent larger in the fitter children. Professor Art Kramer, who led the study published in the journal Brain Research, said the findings had important implications for encouraging individuals to take part in sport from a young age."We knew that experience and environmental factors and socioeconomic status all impact brain development," he said. "If you get some terrible genes from your parents, you can"t really fix that, and it"s not easy to do something about your economic status.But here"s something that we can do something about." | ||

A.genetic factor B.economic status C.physical fitness D.economic development | ||
阅读理解 Some scientists say that animals in the oceans are increasingly threatened by noise pollution caused by human beings. The noise that affects sea creatures comes from a number of human activities. It is caused mainly by industrial underwater explosions, ocean drilling, and ship engines. Such noises are added to natural sounds. These sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves. Decibels (分贝) measured in water are different from those measured on land. A noise of one hundred and twenty decibels on land causes pain to human ears. In water, a decibel level of one hundred and ninety-five would have the same effect. Some scientists have suggested setting a noise limit of one hundred and twenty decibels in oceans. They have observed that noises at that level can frighten and confuse whales. A team of American and Canadian scientists discovered that louder noises can seriously injure some animals. The research team found that powerful underwater explosions were causing whales in the area to lose their hearing. This seriously affected the whales" ability to exchange information and find their way. Some of the whales even died. The explosions had caused their ears to bleed(流血)and become infected (感染). Many researchers whose work depends on ocean sounds are against a limit of one hundred and twenty decibels. They say such a limit would mean an end to important industrial and scientific research. Scientists do not know how much and what kinds of noises are harmful to ocean animals. However, many scientists suspect(怀疑)that noise is a greater danger than they believed. They want to prevent noises from harming creatures in the ocean. 1. According to the passage, which of the following is increasingly dangerous to sea creatures? A. The noises of human activities. B. The noises made by themselves. C. The sound of earthquakes. D. The sound of the ice-breaking. 2. Which of the following is discussed in the third paragraph? A. Different places with different types of noises. B. The very human ears sensitive to all types of noises. C. The same noise measured differently on land and in the ocean. D. The ocean animals" reaction to noises. 3. According to the passage, what will scientists most probably do in the future? A. They will try their best to decrease noise. B. They will work hard to cut down noise pollution. C. They will study the effect of different noises. D. They will protect animals from harmful noises. |
