【正文】 and Wallis decided to test their ideas. “If verification requires an ＄ 80million satellite, one may have to fo 放棄 verification,” says Peterson . “But if it involves a simple experiment, that’s another matter.” Peterson and Wallis are roughly the same size, Wearing identical clothing, one ran 100 metres in heavy rain and the other walked. They weighed their clothes before and after the experiment. This showed that the walker had absorbed of water,while the runner had soaked up only kgs. This is about 40 per cent less ,in line with 符合 the model’s predictions. Belcher says that his team’s work was a bit of fun, and that apart from the confusion over what a typical walking speed is ,their results were similar to those of Peterson and Wallis. “I’m delighted to see that their experiments gave results in qualitative 定性的 agreement with the model,” says Belcher. But why not just take an umbrells? For anyone thinking of taking the easy way out, Wallis has a warning: “Running with an umbrella has a negative impact on your aerodynamics” reading team and the American meteorologists presented different results in investigating___ far people can run per second in a downpour benefits of running for shelter in a downpour people can run fast in a downpour average walking pace in a downpour to the American researchers, the Reading team made an error in calculating___ average walking pace 更多資料請登錄醫(yī)博園論壇 amount of rainfall time and distance running speed of the following, according to the American researchers, gets the least wet? in drizzle in drizzle in heavy rain in heavy rain verified their model predictions by experimenting___ themselves satellite the twins of the same size sophisticated calculating devices simila results ,according to Belcher ,refer to___ amount of rain water absorbed average running speed average walking pace of the above passage 4 Englisher speakers pick up pitch in the right hemisphere of their brains, but speakers of certain other languages perceive it on the left as all depends on what you want to learn from pitch, Donald Wong of the Indians School of Medicine in Indianapolis told the meeting last week. Earlier studies have shown that when an English speaker hears pitch changes, the right prefrontal cortex leaps into action. This fits in with the idea that emotive nuances of languagewhich in English are often carried by the rise and fall of the voiceare perceived on the right. But in “tonal” languages like Thai, Mandarin and Swedish, Pitch not only carries emotional information,but can also alter the meaning of a word .Wong and his colleagues suspected that a speaker of tonal language would register pitch in the left side of the brainin particular Broca’s area ,which processes the linguistic content of language. To test this , the team asked English speakers and Thai speakers to listen 80 pairs of Thai words, and tracked the blood flow in their brains using positron emission volunteers had to decide whether the two words sounded the same, either by consonant or by tone ,In some cases, the words had on intelligible meaning. None of the words was emotionally charged, so even when Thai speakers could understand them, there was no rightside sure enough the Thai speakers could consistently lit up the left side of the brain, especially Broca’s area, while the English speakers did not. The researchers are now planing to repeat the experiment with Thai speakers using whole sentences, plete with emotional information. “Both hemispheres will be engaged,” predict Wong. reason why pitch is registered on the right hemisphere, according to the passage, is that __ to the English language exclusively an emotive nuance of language nuance be easily heard 更多資料請登錄醫(yī)博園論壇 a regular sound the emotionfree words were heard in the test____ registered on the English speakers’ right hemisphere down the blood flow in the volunteers’ brains the Thai speaker’s left hemispheres the exactly the same to the volunteers tonal language____ no pitch pitch with dual functions 雙重職能 superior to the English language more linguestic content than English.
