It plays such an important role in our lives that all fields focus on its study, including one looking at the biology of music. Experts are finding that because of the way our brains process music, learning to play an instrument or just listening to music can have a wide range of benefits.Music education has received a lot of attention. Learning to play an instrument can help children improve math, science, and language skills. One study in Canada tracked childrens IQ scores for nine months, discovering that children who studied music had the biggest test score improvements. The secret may lie in the way reading music and playing notes uses several areas of the brain, increasing our ability to learn school subjects. For example, reading notes improves spatial (空间的) reasoning skills, which are helpful in solving math problems like fractions (分数)Music is also used for medical purposes, such as the treatment of diseases which affect memory. The secret lies in the way the brain processes music. One area near the forehead, the medial prefrontal cortex, connects music with memories stored in two other areas: the amygdale and hippocampus. Thats why an old song can remind you of something that happened years ago. For patients suffering from diseases like Alzheimers, listening to music can help unlock buried memories by strengthening musical pathways to memories.With the evidence of musics benefits pouring in, its no wonder some countries make music study a part of their education systems. People are recognizing that more than just a form of entertainment, music is also great for the brain.1Scientists are studying music because _.A. music can be used for medical treatmentsB. music plays a very important role in our livesC. our brains can possess music in different ways D. music education has received a lot of attention答案与解析B从第一段中“It plays such an important role in our lives that all fields focus on its study, including one looking at the biology of music.”可知，科学家在争辩音乐，由于它在我们的生活中起着重要的作用，选择B项。2According to the Canadian study, which children had increased IQ scores?A.

Spatial reasoning. B. Alzheimers.C. The amygdale and hippocampus. D. The medial prefrontal cortex.答案与解析B从第三段中“For patients suffering from diseases like Alzheimers, listening to music can help unlock buried memories by strengthening musical pathways to memories.”可知，Alzheimer是一种病。选择B项。4What can be the best title for the text?A.

Mature (成熟的)females of the fish species (种类)Paedocypris reach just 7.9mm in length. The species was discovered in the highly acidic (酸性的) peat swamps of the Indonesian island of Sumatra by a team led by Ralf Britz, a zoologist at the Natural History Museum in London. “This is one of the strangest fish that Ive seen in my whole career，” Dr Britz said. “Its tiny, and it lives in acid. I hope that well have time to find out more about them before their habitat disappears completely.” The species lives in dark teacolored swamp waters, which are 100 times more acidic than rainwater. Although these swamps were once thought to be inhabited by very few animals, recent research has shown that they are home to a highly different range of species that occur nowhere else. The peat swamps were damaged by forest fires in 1997, and are also threatened by agriculture. The scientists behind the discovery said that several populations of Paedocypris had already been lost. “Many of the peat swamps we surveyed(调查)throughout SouthEast Asia no longer exist，” Dr Britz said. “Populations of all the miniature(微型的)fish of peat swamps have decreased or disappeared.”Details of the discovery are published today in the journal Proceedings of the Royal Society of London, Series B.5Which of the following would be the best title for the passage? AThe Strangest FishBAcidic Peat SwampsCStrange SpeciesDThe Smallest Backbone Animal答案与解析D依据文章的第一段中的“The smallest animal with a backbone(脊椎)known to science, a fish from the carp family, has been discovered in the peat swamps(沼泽) of Indonesia.”可知，这是文章的中心句。由中心句可知文章主要讲的是：最小的脊椎动物。故选择D项。6Where does the smallest backbone animal live?AIt lives in highly acidic rainwater.BThe species lives in the acidic waters of dark teacoloured swamps.CIt was put in the Natural History Museum in London.DIts habitat disappears completely. 答案与解析B依据文章第四段中的“The species lives in dark teacolored swamp waters, which are 100 times more acidic than rainwater.”可知，这种物种生活在深茶色的沼泽中，其中的水是雨水的酸度的100倍。故选择B项。7According to the passage, the forest fires in 1997 have led to the fact that _.Amany places where these animals lived have been damagedBthe population of the species has increasedCthere are many animals in the acidic peat swamps today D. agriculture doesnt affect the living space of these animals答案与解析A依据文章倒数第三段中的“The peat swamps were damaged by forest fires in 1997, and are also threatened by agriculture.”可知A项正确。其他三项与文章内容不符。8Dr Britzs words imply _.Athe habitat will be more after a period of time Bmany peat swamps that they surveyed have already survivedChe wants to find more miniature fishes before their habitat disappears Dhe wants to have further research答案与解析D依据文章第三段中的“I hope that well have time to find out more about them before their habitat disappears completely.”可知，Dr Britz想进一步了解它们，在他们完全灭亡之前。故选择D项。
