A few degrees can make a big difference when it comes to food storage. Foods can go bad if they get too warm. But for many of the world’s poor, finding a good way to keep food cool is difficult. Refrigerators are costly and they need electricity.
Yet spoiled food not only creates health risks but also economic losses. Farmers lose money when they have to throw away products that they cannot sell quickly.
But in nineteen ninety-five a teacher in northern Nigeria named Mohammed Bah Abba found a solution. He developed the “Pot-in-Pot Preservation/Cooling System.” It uses two round containers made of clay. A smaller pot is placed inside a larger one. The space between the two pots is filled with wet sand. The inner pot can be filled with fruit, vegetables or drinks. A wet cloth covers the whole cooling system.
Food stored in the smaller pot is kept from spoiling through a simple evaporation(蒸发) process. Water in the sand between the two pots evaporates through the surface of the larger pot, where drier outside air is moving.
The evaporation process creates a drop in temperature of several degrees. This cools the inner pot and helps keep food safe from harmful bacteria. Some foods can be kept fresh this way for several weeks.
People throughout Nigeria began using the invention. And it became popular with farmers in other African countries. Mohammed Bah Abba personally financed the first five thousand pot-in-pot systems for his own community and five villages nearby.
In two thousand, the Rolex Watch Company of Switzerland honored him with the Rolex Award for Enterprise. This award recognizes people trying to develop projects aimed at improving human knowledge and well-being. A committee considers projects in science and medicine, technology, exploration and discovery, the environment and cultural history. Winners receive financial assistance to help develop and extend their projects.

(2013·高考四川卷，E)Fear may be felt in the heart as well as in the head，according to a study that has found a link between the cycles of a beating heart and the chance of someone feeling fear.
Tests on healthy volunteers found that they were more likely to feel a sense of fear at the moment when their hearts are contracting(收缩) and pumping blood around their bodies，compared with the point when the heartbeat is relaxed.Scientists say the results suggest that the heart is able to influence how the brain responds to a fearful event，depending on which point it is at in its regular cycle of contraction and relaxation.
Sarah Garfinkel at the Brighton and Sussex Medical School said：“Our study shows for the first time that the way in which we deal with fear is different depending on when we see fearful pictures in relation to our heart.”
The study tested 20 healthy volunteers on their reactions to fear as they were shown pictures of fearful faces.Dr Garfinkel said，“The study showed that fearful faces are better noticed when the heart is pumping than when it is relaxed.Thus our hearts can also affect what we see and what we don’t see－and guide whether we see fear.”
To further understand this relationship，the scientists also used a brain scanner(扫描仪) to show how the brain influences the way the heart changes a person’s feeling of fear.
“We have found an important mechanism by which the heart and brain ‘speak’to each other to change our feelings and reduce fear，”Dr Garfinkel said.
“We hope that by increasing our understanding about how fear is dealt with and ways that it could be reduced，we may be able to develop more successful treatments for anxiety disorders，and also for those who may be suffering from serious stress disorder.”
【小题1】What is the finding of the study?
| A．One’s heart affects how he feels fear. |
| B．Fear is a result of one’s relaxed heartbeat. |
| C．Fear has something to do with one’s health. |
| D．One’s fast heartbeats are likely to cause fear. |
| A．volunteers’ heartbeats when they saw terrible pictures |
| B．the time volunteers saw fearful pictures and their health conditions |
| C．volunteers’ reactions to horrible pictures and data from their brain scans |
| D．different pictures shown to volunteers and their heartbrain communication |
| A．Order. | B．System. |
| C．Machine. | D．Treatment. |
| A．treating anxiety and stress better |
| B．explaining the cycle of fear and anxiety |

It’s the dirty little secret many shampoo companies don’t want you to know. When you wash your hair with certain traditional chemical shampoos, you may actually be removing your hair and scalp（头皮）of their natural oils. These shampoos generate a thick bubble to clean hair, they can also create dryness, curl, dullness, and color fade. We then spend a lot of time and money on products that are effectively repairing the damage caused by shampoo.
Chaz Dean got tired of clients leaving his salon raving about their color and the feeling of their hair---brassy（似黄铜的） and dull. He knew the main cause was likely their shampoo, so he started experimenting with various ingredients, including natural herbs and botanicals, that he knew had cleansing（弄干净）and hydrating (保湿的) properties.
The result was a totally new approach to the way we cleanse our hair. It’s called WEN® Cleansing Conditioner. WEN® contains a super-hydrating natural herbs and botanicals mixture of glycerin, chamomile(甘菊), rosemary, calendula, and Cherry bark, which when combined, will both cleanse the hair as well as give shine and softness, even to damaged hair.
WEN® is a 5-in-1 formula（配方） that takes the place of your shampoo, And the most amazing thing about it is that it cleanses without bubble. Instead, when mixed with water, it creates a smooth bubble for shiny, healthy-looking, manageable results. The first time you try it certainly feels strange, but the results speak for themselves.
Before being marketed, WEN® went through extensive consumer tests, and the results were impressive. More than 90 percent of the participants in the studies reported that their hair was more shiny, less frizzy, and had more bounce.
WEN® is recommended for all hair types, and once you start using it, it will become the only cleanser/conditioner you will want to include in your daily routine.

Every year in late spring at Wild Friends, the wildlife health center, workers receive baby animals, including songbirds and rabbits. This is the busiest time when workers care for and raise all the little ones before sending them back into the wild.
There are many reasons for these little animals' coming to the center. First of all, street cats or dogs catch, injure or take away little birds from their nests. Sometimes people catch baby animals and keep them at home, giving them food that they are not used to. It would make them sick. Most people don't realize that it's against law to get live animals out of their nests.
As for songbirds, people often find them on the ground in their yards, thinking they have no other choice but to leave them on the ground to die. This is because many people wrongly believe that once a bird is touched by a person, its mother will not accept this child bird. But that's not true.
If a little bird falls out of the nest, you should check whether it is injured. If not, you should put the bird back in the nest. If the bird is injured, call your local wildlife center quickly.
As for the progress of protecting wild animals, people at Wild Friends devote all their energy to this work. Over the last weeks, they have been able to send many of the birds and rabbits that came here earlier this spring back to nature.
【小题1】Which is the busiest season for workers at Wild Friends?
| A．Spring | B．Summer. | C．Autumn. | D．Winter. |
| A．Giving them food they don't like. | B．Letting them play with children. |
| C．Leaving them on the ground. | D．Bringing them to the center. |
| A．wait for its mother | B．help it go back home |

The Segway Human Transporter was invented by Dean Kamen．It is a two-wheeled vehicle designed for a single rider standing upright over its single axle（轴） and navigate using a set of handlebars resembling those on a bicycle．Electrically powered, it could travel over 15 miles on a single charge and reach speeds up to twelve miles per hour．Its speed and direction can be controlled by riders' changing their weights．
A college dropout and self-taught engineer, Kamen already held over 100 patents for his inventions when he developed the one he hoped would revolutionize short-distance travel．While still in college, Kamen started developing the medical devices （设备） that made his name．Later, he changed focus to the challenges faced by wheelchair users．His robotic wheelchair known as IBOT could climb stairs．This robot ended up paving the way for the Segway．
Before showing his most recent invention, Kamen had kept it a top secret for months．When it turned out to be little more than a motor scooter, many publicly expressed their disappointment．On closer examination, however, even his critics（批评家） had to admit that the vehicle was an engineering achievement．It answered the prayers of anyone who is worn out when walking downtown．Not everyone welcomed the Segway's arrival, though．Some complained it was too expensive, while others said it would further weaken the average American ' s fitness．A Japanese inventor even accused Kamen of stealing the idea for the Segway from him．
Despite the controversy, the U．S．postal service began using Kamen's invention a month after its appearance, and a factory was built with plans to produce about 40,000 Segways every month．The argument is still on whether the Segway will be remembered as the greatest invention since the light bulb, or just another forgettable electronic device．Anyway, trips to the local supermarket will never be the same again．

Global warming is causing more than 300,000 deaths and about $125 billion in economic losses each year, according to a report by the Global Humanitarian Forum, an organization led by Kofi Annan, the former United Nations secretary general.
The report, to be released Friday, analyzed data and existing studies of health, disaster, population and economic trends. It found that human-influenced climate change was raising the global death rates from illnesses including malnutrition and heat-related health problems.
But even before its release, the report drew criticism from some experts on climate and risk, who questioned its methods and conclusions. Along with the deaths, the report said that the lives of 325 million people, primarily in poor countries,were being seriously affected by climate change. It projected that the number would double by 2030.
Roger Pielke Jr., a politicalscientist at the University of Colorado, Boulder, who studies disaster trends, said the Forum’s report was “a methodological embarrassment” because there was no way to distinguish deaths or economic losses related to human-driven global warming amid（在...中间） the much larger losses resulting from the growth in populations and economic development in vulnerable(易受伤害的) regions. Dr. Pielke said that “climate change is an important problem requiring our utmost attention.” But the report, he said, “will harm the cause for action on both climate change and disasters because it is so deeply flawed(有瑕疵的).”
However, Soren Andreasen, a social scientist at Dalberg Global Development Partners who supervised the writing of the report, defended it, saying that it was clear that the numbers were rough estimates. He said the report was aimed at world leaders, who will meet in Copenhagen in December to negotiate a new international climate treaty.
In a press release describing the report, Mr. Annan stressed the need for the negotiations to focus on increasing the flow of money from rich to poor regions to help reduce their vulnerability to climate hazards while still controling the emissions of the heat-trapping gases. More than 90% of the human and economic losses from climate change are occurring in poor countries, according to the report.
【小题1】 What is the finding of the Global Humanitarian Forum?
| A．Rates of death from illnesses have risen due to global warming. |
| B．Global temperatures affect the rate of economic development. |
| C．Malnutrition has caused serious health problems in poor countries. |
| D．Economic trends have to do withpopulation and natural disasters. |
| A．It caused a big stir in developing countries. |
| B．It was warmly received by environmentalists. |
| C．It caused a lot of interest in the scientific circles. |
| D．It was challenged by some climate and risk experts. |
| A．Its conclusions are based on carefully collected data. |
| B．It is vulnerable to criticism if the statistics are closely examined. |
| C．It will give rise to heated discussions at the Copenhagen conference. |
| D．Its rough estimates are meant to draw the attention of world leaders. |
| A．How human and economic losses from climate change can be reduced. |
| B．How rich countries can better help poor regions reduce climate hazards. |
| C．How emissions of heat-trapping gases can be reduced on a global scale. |
| D．How rich and poor regionscan share responsibility in curbing global warming. |

Can dogs and cats live in peace in the same home? People who are thinking about adopting a dog as a friend for their cat are worried that they will fight. A recent research has found a new way for success. According to the study, if the cat is adopted before the dog, and if they are introduced when still young (less than 6 months for cats, a year for dogs), it is highly probable that the two pets will get along swimmingly. Twothirds of the homes interviewed reported a positive relationship between their cat and dog.
However, it wasn't all sweetness and light. There was a reported coldness between the cat and dog in 25% of the homes, while attacking and fighting were observed in 10% of the homes. One reason for this is probably that some of their body signals are just opposite. For example, when a cat turns its head away it signals attack, while a dog doing the same signals admitting defeat.
In homes with cats and dogs living peacefully, researchers observed a surprising behaviour. They are learning how to talk each other's language. It is a surprise that cats can learn how to talk “dog”, and dogs can learn how to talk “cat”.
What's interesting is that both cats and dogs have appeared to develop their intelligence. They can learn to read each other's body signals, suggesting that the two may have more in common than was previously thought. Once familiar with each other's presence and body language, cats and dogs can play together, greet each other nose to nose, and enjoy sleeping together on the sofa. They can easily share the same water bowl and in some cases groom (梳理) each other.
The advantage of this research on cats and dogs may not only about pets — to people who don't get along, including neighbors, colleagues at work, and even world superpowers. If cats and dogs can learn to get along, surely people have a good chance.
【小题1】The underlined word “swimmingly” in Paragraph 1 is closest in meaning to .
| A．early | B．sweetly |
| C．quickly | D．suprisingly |
| A．they are cold to each other |
| B．they look away from each other |

| D．they are introduced at an early age |
| A．They eat and sleep together. |
| B．They observe each other's behaviors. |
| C．They learn to speak each other's language. |
| D．They know something from each other's voices. |
| A．We should learn to live in peace. |

Is your family interested in buying a dog? A dog can be a pleasant companion（伙伴） to your family, but if you choose the wrong kind of dog，you will have a lot of troubles.
Families should sit down and thoroughly discuss the possible problems before buying a dog. Even if the children in your family are the ones who want the dog, the parents are the ones who are really responsible for seeing that the animal is properly cared for. If you don’t know much about dogs, it is a good idea to go to the library for books about different kinds of dogs, as well as books about how to train a young dog. In reading about the different breeds(种类)you should know that a dog described(描述)as very alert(机敏灵活的)may be too active. When a book describes a dog as an excellent hunting dog, it probably means that the dog won’t be happy living in a small house. Dog breeds vary(变化)in popularity as the years go by. One of the most popular dogs these days is the German shepherd（牧羊犬）. This is because it provides protection as well as companionship（陪伴）. The family should be warned that these dogs grow up to be very big, and may be too powerful for children to control. If space is limited, a toy dog may be a good choice. These dogs are very small and easy to train. They don’t need to be walked daily, since they can exercise in the home.
【小题1】According to the passage, one can get information about different kinds of dogs .
| A．by going to the library |
| B．by asking someone who has enough experience about different kinds of dogs |

Look, this is the first plane in the world to be created using the new technology of “3D printing”. The airplane was built using only a computer—but it can fly at a speed of 100mph and has a two-meter wingspan.
It was produced using a special nylon laser printer that builds up something layer-by-layer. The parts were made separately and attached using a “snap fit” technique so the aircraft could be put together without tools in minutes.
No fasteners at all were used in the manufacture of the plane. Unmanned and electrically powered, the plane can travel in near silence and is also equipped with a small autopilot system. The special production process used is known as “laser sintering(激光烧结)”and allows the designers to create shapes and structures that would normally include costly manufacturing techniques. This technology allows a highly-tailored aircraft to be developed from your own design to first flight in days, while using traditional materials and techniques would take months. And because no tooling is required for manufacture, major changes to the shape and scale of the aircraft can be made with no extra cost.
Professor Jim Scanlon, who led the team, said, “The process allows the design team to revisit historical techniques and ideas that would have been too expensive using traditional manufacturing.” He added, “This form of structure is very firm and lightweight, but very complex. If it was manufactured traditionally it would require a large number of individually tailored parts that would have to be connected or fastened at great expense.”
The new printed plane is known as the Southampton University Laser Sintered Aircraft—or SULSA for short—and is part of a wider project using cutting-edge manufacturing techniques. The University of Southampton has been at the leading position of Unmanned Aerial Vehicle development since the early 1990s.
【小题1】Which of the following would be the best title for the text?
A. Revolutionary Breakthrough of 3D Printer
Scientists Create Aircraft with High Speed
C. New Designed Airplane with New Techniques.
D. The World’s first 3-D printed Airplane, SULSA
【小题2】How could the plane work while flying?
| A．It should be controlled by an autopilot system. |
| B．It should be controlled by “laser sintering”. |
| C．A pilot controls it using a remote control. |
| D．A pilot with high techniques controlled it. |
| A．it produces little noise while flying |
| B．it is manufactured in quite a short time |
| C．it only requires simple and cheap tools |
| D．it needn’t extra cost if changes are made |
| A．produce firmer and lighter real planes easily |
| B．connect and fasten tailor parts for real planes |
| C．copy earlier planes to study their techniques |
| D．find differences by studying the traditional ones |
