For some people, music is no fun at all. About four percent of the population is what scientists call “amusic.” People who are amusic are born without the ability to recognize or reproduce musical notes (音调). Amusic people often cannot tell the difference between two songs. Amusics can only hear the difference between two notes if they are very far apart on the musical scale.
As a result, songs sound like noise to an amusic. Many amusics compare the sound of music to pieces of metal hitting each other. Life can be hard for amusics. Their inability to enjoy music set them apart from others. It can be difficult for other people to identify with their condition. In fact, most people cannot begin to grasp what it feels like to be amusic. Just going to a restaurant or a shopping mall can be uncomfortable or even painful. That is why many amusics intentionally stay away from places where there is music. However, this can result in withdrawal and social isolation. “I used to hate parties,” says Margaret, a seventy-year-old woman who only recently discovered that she was amusic. By studying people like Margaret, scientists are finally learning how to identify this unusual condition.
Scientists say that the brains of amusics are different from the brains of people who can appreciate music. The difference is complex, and it doesn’t involve defective hearing. Amusics can understand other nonmusical sounds well. They also have no problems understanding ordinary speech. Scientists compare amusics to people who just can’t see certain colors.
Many amusics are happy when their condition is finally diagnosed. For years, Margaret felt embarrassed about her problem with music. Now she knows that she is not alone. There is a name for her condition. That makes it easier for her to explain. “When people invite me to a concert, I just say, ‘No thanks, I’m amusic,’” says Margaret. “I just wish I had learned to say that when I was seventeen and not seventy.”
【小题1】Which of the following is true of amusics?
| A．Listening to music is far from enjoyable for them. |
| B．They love places where they are likely to hear music. |
| C．They can easily tell two different songs apart. |
| D．Their situation is well understood by musicians. |
| A．dislikes listening to speeches | B．can hear anything nonmusical |
| C．has a hearing problem | D．lacks a complex hearing system |
| A．her problem with music had been diagnosed earlier |
| B．she were seventeen years old rather than seventy |
| C．her problem could be easily explained |
| D．she were able to meet other amusics |
| A．Amusics’ strange behaviours. |
| B．Some people’s inability to enjoy music. |
| C．Musical talent and brain structure. |
| D．Identification and treatment of amusics. |
【小题1】A
【小题2】C
【小题3】A
【小题4】B
解析试题分析：文章讲述的是世界上有一群天生不喜欢听音乐的人，被称之为amusic，这些人听力上没有任何问题，只是不喜欢听音乐，也无法欣赏音乐。很多人在之前都因此而苦恼，现在有了科学的解释，他们可以摆脱那种尴尬、不自在的处境了。
【小题1】根据第一段“For some people, music is no fun at all”可知，A项正确，意为，“对于某些人来说，听音乐并不是开心的事情”和A项的听音乐对他们来说远非是愉快的相同。因此，B项也是错误的。根据第一段的“People who are amusic are born without the ability to recognize or reproduce musical notes (音调). Amusic people often cannot tell the difference between two songs. ”可知，CD两项错误。
【小题2】该段前两句讲的是不爱听音乐的人和喜欢听音乐的人是不同的，他们之间的区别很复杂，但是那have no problems understanding ordinary speech. ”又讲到了这些不爱听音乐的人在理解其他非音乐的声音或者演讲的时候是没有问题的，目的是为了强调他们是正常的，没有什么缺陷的，因此defective hearing指的是C项的a hearing problem,即听觉有问题。句意为，他们之间的区别是很负责的，但并不包括听觉有问题这种情况。
【小题3】I just wish I had learned to say that when I was seventeen and not seventy.意为，我希望我在十七岁的时候就学会了这样说（指的是No thanks, I’m amusic这句，意为，谢谢你，我是一个不喜欢听音乐的人），而不是到了七十岁才学会。从最后一段我们知道，their condition is finally diagnosed (诊断)他们的这种状况终于最后确诊了，他们都属于amusic，但是这来的太迟了，对于Margaret来说，因为之前她总是Margaret felt embarrassed about her problem感到很尴尬，因此她希望她年轻的时候，就可以有现在这样的诊断。
【小题4】全文主要讲述的是不喜爱听音乐的一类人，被称之为amusic，他们之前都没有得到统一的诊断或者认识，直到现在。因此选择B项，Some people’s inability to enjoy music意为，一些人无法欣赏音乐。A项，错在strange behaviors，文章只是说他们不喜欢有音乐的地方，并没有讲到他们其他的一些奇怪的举动。C项Musical talent and brain structure音乐天赋和大脑构造，明显与文章大意不符。D项中错在treatment，意为治疗，文章并没有讲到如何帮助这些人治疗他们的问题。因此排除D。

Chinese scientists have found a new way to use cells found in human urine （尿液）that could aid in the treatment of a range of nerve disorders.That is a new technique for reprogramming cells in human urine into nerve progenitor cells that can grow into multi-functional nerve and brain cells.
The technique is expected to be used in the study and treatment of nerve disorders such as Parkinson's disease, Alzheimer's disease and other nerve disorders.
Pei Duanqing, a professor at Guangzhou Institutes of Biomedicine and Health, Chinese Academy of Sciences, said his research team has combined an episomal system to deliver reprogramming factors with a chemically defined culture medium to reprogram kidney epithelial(肾表皮) cells in urine into NPCs.
These NPCs, normally only found in the human brain, were later proven to be transgene-free and self-renewing, he said.
"These nerve and brain cells can survive for up to one month when transplanted into the brain of a newborn rat," said Pei. "My team is working hard to understand why our experimental condition allowed the urine cells to become NPCs, because we want to improve the technique and make it more efficient".
Scientists have long searched to treat and study neural disorders by obtaining and transplanting neural stem cells. However, the previous method of getting and using cells from either fetal (胎儿)or adult human tissue remains challenging due to ethical concerns and immune system rejections, he said.
Pei hopes the discovery will be used to generate NPCs from patients with nerve disorders such as Parkinson's disease. "These NPCs from patients may help us discover new drugs for these diseases."
"It is a remarkable advance in the stem cell field. The results and methods obtained from this study will be of great value and significance to the field, " said Fred Gage,a professor with the Salk Institute for Biological Studies.
【小题1】What is the passage mainly about?
| A．NPCs are beneficial in treating human diseases. |
| B．Chinese scientists succeeded in making NPCs from human urine. |
| C．Chinese scientists have found cures for all diseases. |
| D．A new technique was used to study the use of human urine |

The need to feed a growing population is putting much pressure on the world's supply of water. With 97% of the world's water too salty to be drunk or used in agriculture, the worldwide supply of water needs careful management, especially in agriculture. Although the idea of a water shortage(短缺)seems strange to someone fortunate enough to live in a high rainfall country, many of the world's agricultural industries experience constant water shortages.
Although dams can be built to store water for agricultural use in dry areas and dry seasons, the costs of water redistribution(重新分配)are very high. Not only is there the cost of the engineering itself, but there is also an environmental cost to be considered. Where valleys(山谷)are flooded to create dams, houses are lost and wildlife homes destroyed. Besides, water may flow easily through pipes to fields, but it cannot be transported from one side of the world to the other. Each country must therefore rely on the management of its own water to supply its farming requirements.
This is particularly troubling for countries with agricultural industries in areas dependent on irrigation (灌溉). In Texas, farmers' overuse of irrigation water has resulted in a 25% reduction of the water stores. In the Central Valley area of southwestern USA, a huge water engineering project provided water for farming in dry valleys, but much of the water use has been poorly managed.
Saudi Arabia's attempts to grow wheat in desert areas have seen the pumping of huge quantities of irrigation water from underground reserves. Because there is no rainfall in these areas, such reserves can only decrease, and it is believed that fifty years of pumping will see them run dry.
【小题1】From the first two paragraphs we learn that________.
| A．much of the world's water is available for use |
| B．people in high rainfall countries feel lucky |
| C．water can be easily carried through pipes across the world |
| D．the costs of water redistribution should be considered |
| A．The water stores in Texas have been reduced by 75%. |
| B．Most industries in the world suffer from water shortages. |
| C．The underground water in Saudi Arabia might run out in 50 years. |
| D．Good management of water use resulted from the project in the Central Valley. |
| A．Steps to improving water use management. |
| B．Ways to reduce the costs of building dams. |
| C．Measures to deal with worldwide water shortages. |
| D．Approaches to handling the pressure on water supply. |
| A．water supply and increasing population |
| B．water use management and agriculture |
| C．water redistribution and wildlife protection |
| D．water shortages and environmental protection |

About ten men in every hundred suffer from color blindness in some way. Women are luckier, only about one in two hundred if affected in this matter. Perhaps, after all, it is safer to be driven by a woman.
There are different forms of color blindness. In some cases a man may not be able to see deep red. He may think that red, orange and yellow are all shades of green. Sometimes a person can’t tell the differences between blue and green. In rare cases an unlucky man sees everything in shades of green--- a strange world in deed.
Color blindness in human beings is a strange thing to explain. In a single eye there are millions very small things called “cones”. These help us see in a bright day and tell the differences between colors. There are also millions of “rods”, but these are used for seeing when it is nearly dark. They show us shapes(形状) but not color. Some insects have favorite colors. Mosquitoes like blue but do not like yellow. A red light will not attract insects but a blue lamp will. In similar way human being also have favorite colors. Yet we are lucky. With the aid of cones in our eyes we can see many beautiful colors by day and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible colors around us.
【小题1】The passage is mainly about ______.
| A．color and its surprising effects on drivers |
| B．women being luckier than man in that fewer of them are color blind |
| C．danger caused by color blindness |
| D．color blindness and how our eyes tell different colors and shapes |
| A．tell different colors | B．see in weak light |
| C．tell different shapes | D．tell orange from yellow |
| A．Women are more careful. |
| B．There are fewer color blind women. |
| C．Women are fonder of driving than men. |
| D．Women are weaker but quicker in thinking. |
| A．Not all of them have the same problem in recognizing colors. |
| B．None of them can see deep red but all can tell blue from green. |
| C．None of them can tell blue from green but all can see deep red. |
| D．All of them are lucky enough to see everything in shades of green. |

Monkeys prefer heavy metal to classical music, according to researchers at the University of Wisconsin whose findings are published this week in Biology Letters.
Scientists played a selection of music to a group of South American cotton-top monkeys but the only sound that got a reaction were from the heavy metal band Metallica. They were seemingly disinterested in Led Zeppelin, Miles Davis and Bach, but after the beautiful sound of Master of Puppets by Metallica was played the monkeys calmed down.
"Monkeys interpret rising and falling sounds differently than humans. Oddly, their only response to several samples of human music was a calming response to the heavy-metal band Metallica," said Professor Charles Snowdon, from the University of Wisconsin-Madison.
Rather than making them excited or aggressive, the heavy metal tracks had a comforting effect. Dr Snowdon, who teamed up with National Symphony Orchestra musican David Teie, also played the monkeys music composed specifically for them. Although they enjoyed Metallica, they were much more interested in these pieces.
A melody(乐曲) based on the short calls of scared monkeys led to anxiety levels rapidly growing, researchers found, while one based on long calls the creatures make when they are happy had a calming effect.
Frans B.M. de Waal, a professor of psychology at Emory University who studies animals, said the findings appear to say more about how monkeys respond to the sounds they make than they do about music or the evolution of music.
Dr Snowdon no longer has a monkey colony to use in his research, but he said his co-author David Teie is exploring the concept of music for cats.
"If we understand how we can affect their emotional states through using musical sound and aspects of our speech, maybe those of us living with companion animals can have a better relationship with them, too," Snowdon said.
【小题1】The research mentioned in the passage is mainly about ______.
| A．the change of music over time | B．animals’ response to music |
| C．special music for animals | D．the origin of music |
| A．looked anxious | B．became restless |
| C．felt at ease | D．made long calls |
| A．of Led Zeppelin | B．of Miles Davis |
| C．of Metallica | D．specially composed for them |
| A．build better ties between animals and humans |
| B．compare monkeys and cats in term of music |
| C．develop new music based on animals’ calls |
| D．find better ways to keep animals under control |

400-year-old plants from the Little Ice Age were brought back to life, which could help us understand how the Earth will deal with climate change.
Moss(藓类植物) found buried beneath the Teardrop glacier(冰川) on Ellesmere Island in Canada has been brought back to life. Findings suggest that these plants could help repopulate regions exposed by melting ice caps. Plants that were buried beneath thick ice in Canada more than 400 years ago and were thought to have frozen to death have been brought back to life by Canadian scientists.
Samples of the moss plant, covered by the glacier during the Little Ice Age of 1550 to 1850 AD, were replanted in a lab at the University of Alberta and grew new stems(茎). Researchers now think these findings can give indication as to how regions can recover as the ice covering them melts.
Biologist Dr. Catherine La Farge and her team at the University of Alberta were exploring the region around the Teardrop glacier on Ellesmere Island. Ice on Ellesmere Island region has been melting at around four meters each year for the past nine years. This means that many areas of land that were previously covered by ice have since been exposed. Many ecosystems that were thought to have been destroyed during the Little Ice Age between 1550 and 1850 AD can now be studied, including many species that have never been studied before.
While examining an exposed area of land, La Farge and her team discovered a small area of moss called Aulacomnium turgidum. It is a type of bryophyte(苔藓类植物) plant that mainly grows across Canada, the US and the Highlands of Scotland.
Dr La Farge noticed that the moss had small patches of green stems, suggesting it is either growing again or can be encouraged to repopulate. Dr La Farge told the BBC, “When we looked at the samples in detail and brought them to the lab, I could see some of the stems actually had new growth of green branches, suggesting that these plants are growing again, and that blew my mind. When we think of thick areas of ice covering the landscape, we’ve always thought that plants have to come from refugia(濒绝生物保护区), never considering that land plants come from underneath a glacier. It’s a whole world of what’s coming out from underneath the glacier that really needs to be studied. The ice is disappearing pretty fast. We really have not examined all the biological systems that exist in the world; we don’t know it all.”
Dr La Farge took samples of the moss and, using carbon-dating techniques, discovered that the plants date back to the Little Ice Age. Dr La Farge’s team took the samples, planted them in dishes full of nutrient-rich potting soil and fed them with water.
The samples were from four separate species including Aulacomnium turgidum, Distichium capillaceum, Encalypta procera and Syntrichia ruralis. The moss plants found by Dr La Farge are types of bryophytes. Bryophytes can survive long winters and regrow when the weather gets warmer.
However, Dr La Farge was surprised that the plants buried under ice have survived into the twenty-first century. Her findings appear in proceedings（论文集）of the National Academy of Sciences.
【小题1】Dr La Farge’s research is of great importance to ________.
| A．knowing what the plants during the Little Ice Age were like |
| B．understanding how ecosystems recover from glaciers. |
| C．regrowing many species that have been destroyed before. |
| D．figuring out the effects of melting ice caps on moss. |
| A．surprised me | B．greatly frightened me |
| C．put my doubt out of my mind | D．was exactly what I had in my mind |
| A．lives better in small groups |
| B．is very active in hot weather |
| C．is strong enough to survive coldness |
| D．is chosen from Canadian refugia |
| A．Bryophyte ecology is greatly affected by climate change. |
| B．400-year-old moss’s survival is a mystery to solve. |
| C．Moss in ancient times was discovered in Canada. |
| D．400-year-old plants were brought back to life. |

The relationship between humans and animals has always been complex. Some cultures have developed entire belief systems around favored animals. Even in cultures with less formal belief systems, connections between people and animals still lead to commonly accepted opinions about animals.
These belief systems usually develop around the animals that interact (互动) with humans most frequently. Therefore, it should not be surprising that so many stories surround the most common of animals: rats. Rats live side by side with humans all over the world and regularly interact with people. Human-rat coexistence may be common all around the world, but different cultures respond to that closeness in different ways.
In the United States and Europe, one typical attitude is that the rat is a pest. This could be due to the common belief that rats spread disease. Actually, they don’t, at least not directly, but many people don’t know that. The Pied Piper of Hamlin, a well-known children’s story, is one example of how rats have been described in Western literature: in that story, rats cause such a problem that a town has to hire a piper to call them all away.
In many Latin American countries, the rat is described in a very different way. The story of the tooth fairy (a fairy believed by children to leave money while they sleep in exchange for a tooth that has come out) is common all over the world, but in Latin America, the “fairy” is a rat! Rats do have very strong teeth, which could explain the association. Clearly, this shows another attitude toward rats that is much more positive.
Yet another attitude toward the rat can be seen in the Chinese Zodiac (生肖). The Rat is one of the animals of the Zodiac. Like the other zodiac animals, the Rat is neither entirely good nor entirely bad. It’s described as clever and friendly, but also tricky and not entirely honest. That may be the most accurate description of the rat so far. Whether you like rats or not, it’s hard to deny their reputation for cleverness.
As many people are discovering these days, rats can even make excellent pets, so long as you remember to close the cage carefully!
【小题1】What does the passage mainly talk about?
| A．A trend of keeping rats as pets. |
| B．How different cultures look at rats. |
| C．How humans get along with animals. |
| D．Favored animals in different cultures. |
| A．unpleasant | B．honest | C．smart | D．unusual |
| A．the tooth fairy is lovely |
| B．rats look very frightening |
| C．rats are welcome in Latin American countries |
| D．the story of the tooth fairy is common all over the world |
| A．don’t spread disease |
| B．should be treated as pests |
| C．are fairly described in the Chinese Zodiac |

“If you want to see a thing well, reach out and touch it!”
That may seem a strange thing to say. But touching things can help you to see them better.
Your eyes can tell you that a glass ball is round. But by holding it in your hands, you can feel how smooth and cool the ball is. You can feel how heavy the glass is. When you feel all these about the ball, you really see it. With your skin, you can feel better. For example, your fingers can tell the difference between two coins in your pocket. You can feel a little drop of water on the back of your hand, too. You can even feel sounds against your skin. Have you ever wanted to know why some people like very loud music? They must like to feel the sounds of music.
All children soon learn what “Don't touch!”means. They hear it often. Yet most of us keep on touching things as we grow up. In shops, we touch things we might buy: food, clothes. To see something well, we have to touch it. The bottoms of our feet can feel things, too. You know this when you walk on warm sand, cool grass or a hard floor. All feel different under your feet.
There are ways of learning to see well by feeling. One way is to close your eyes and try to feel everything that is touching your skin. Feel the shoes on your feet, the clothes on your body, the air on your skin. At first, it is not easy to feel these things. You are too used to them!
Most museums are just for looking. But today some museums have some things to touch. Their signs say, “Do touch!” There you can feel everything on show.
If you want to see better, reach out and touch. Then you will really see!
【小题1】By touching things, .
| A．you will have a strange feeling |
| B．you will learn how to reach out your hand |
| C．you can learn more about them |
| D．you can tell what colors they really are |
| A．Touching by Feeling | B．To See or to Feel |
| C．To See Better—Feel | D．Ways of Feeling |
| A．Your fingers. | B．Your eyes. | C．Your skin. | D．Your back. |
| A．Sounds. | B．Darkness. | C．Water. | D．Coins. |
| A．Touching is helping us to see better. |
| B．Our skips may help us enjoy music. |
| C．People don't have to learn to feel. |

Do you know mulch? Mulch is a protective cover of material that is spread on top of soil. It is usually made out of organic material, like crop waste. Farmers may keep the remains of corn or other crops on top of the soil. This creates mulch on the soil surface. The plant remains help protect the soil against wind and water damage. Mulching is one of the best things people can do for their plants. It also helps keep the soil from getting dry, and reduces the need for watering plants. It also limits temperature changes in the soil. And it stops unwanted plants, or weeds, from growing.
Organic mulch improves the condition of soil. As the mulch breaks down, it provides material which keeps the soil from getting hard. This improves the growth of roots and increases the movement of water through the soil. It also improves the ability of the soil to hold water. Organic mulch contains nutrients for plants. It also provides good environment for earthworms and other helpful living things in the soil.
It is easy to find organic mulch materials. Cut-up leaves and small pieces of tree bark can be used. Grass cuttings are also a good mulch for plants. Mulch from news- papers works well in controlling weeds.
The best time to add mulch depends on your goal. Mulch provides a thick barrier between the soil and the air. This helps to reduce temperature changes in the soil. As a result, mulched soil will be cooler than other soil in the summer. In winter, the mulched soil may not freeze as deeply as other soil. The best time is after the ground has frozen, but before the coldest weather arrives. Spreading mulch before the ground has frozen may attract small animals searching for a warm place to spend the winter. Delaying the spreading should prevent this problem. The animals will probably find another place to live.
【小题1】The author tells us the following EXCEPT ______.
| A．what mulch is and its advantages |
| B．the best time to add mulch |
| C．the bad effects of mulch |
| D．what can be mulch on the soil surface |
| A．tree barks | B．plastic | C．grass cuttings | D．cut-up leaves |
| A．improve the condition of soil |
| B．improve the ability of the soil to hold water |
| C．provide a good environment for earthworms |
| D．improve the growth of roots and increase the movement of water through the soil |
| A．the best time to add mulch is in spring and summer |
| B．the best time to add mulch is after the coldest weather arrives |
| C．the best time to add mulch is exactly the same time of each year |
| D．choosing the best time to add mulch can avoid attracting small animals |
