(2013·宜春五校联考)Technology is making life easier for some dairy farmers.They use robotic systems to milk their cows.Cows are trained to follow a series of paths that lead to milking stations.Only one cow at a time can enter a station.
Once inside，the cow is rewarded with food.As the cow eats，a robotic arm cleans and connects the animal to the milking machine.A few minutes later，milking is complete.The gate is opened，the cow is released and the next cow enters.
The robotic systems are designed to operate 24 hours a day.The cows get to decide when they want to be milked.Cows are milked an average of about three times a day.Some are milked four to six times a day.
The cows wear collars around their necks that identify them to the system.A computer keeps records on their eating and milking.A cow is released from the station if the computer decides it should not be milked.
The automated system also measures the temperature and color of freshly produced milk.Milk is thrown away if it does not pass the tests.
Professor Plaut believes the systems will appeal especially to the next generation of farmers.She means young people who are more interested in technology and less interested in working all the time on the farm.Still，she says the price of robotic milking systems will continue to limit their use.
Doug and Tina Suhr have more than 100 cows on their family farm.Last year it became the fourth farm in southeast Minnesota to get a robotic milking system.A recent story in a local agricultural newspaper said the first robot costs 175,000 dollars.The second costs 150,000 dollars.
Doug told AgriNews that wages that would have been paid for one employee in five years will pay for one robot.He says the increase in milk production reaches a high of more than six kilograms per cow per day.
【小题1】From the first paragraph，we can infer ________.
| A．the robotic system is designed to reduce labor |
| B．cows can be raised by robots in the future |
| C．robots direct cows into milking stations |
| D．cows are kept clean by robots on some farms |
| A．adjust the temperature of milking stations |
| B．judge the quality of fresh milk |
| C．improve the appetite of cows |
| D．keep fresh milk for two weeks |
| A．Because young people have no interest in it. |
| B．Because it is difficult to learn how to use it. |
| C．Because people can't afford to buy it. |
| D．Because it usually causes the waste of milk. |
| A．$150,000～$175,000. |
| B．over $75,000. |
| C．$150,000～$30,000. |

What will power your house in the future？Nuclear，wind，or solar power？According to scientists at the Massachusetts Institute of Technology (MIT) in the US，it might be leaves — but artificial (人造的) ones.
Natural leaves are able to change sunlight and water into energy. It is known as photosynthesis (光合作用)．Now researchers have found a way to imitate this seemingly simple process.
The artificial leaf developed by Daniel Nocera and his colleagues at MIT can be seen as a special silicon chip with catalysts (催化剂)．Similar to natural leaves，it can split water into hydrogen and oxygen when put into a bucket of water. The hydrogen and oxygen gases are then stored in a fuel cell，which uses those two materials to produce electricity，located either on top of a house or beside the house.
Though the leaf is only about the shape of a poker card，scientists claimed that it is promising to be an inexpensive source of electricity in developing countries. “One can imagine villages in India and Africa not long from now purchasing an affordable basic power system based on this technology,” said Nocera at a conference of the American Chemical Society.
The artificial leaf is not a new idea. The first artificial leaf was invented in 1997 but was too expensive and unstable for practical use. The new leaf，by contrast，is made of cheap materials，easy to use and highly stable. In laboratory studies，Nocera showed that an artificial leaf prototype (原型) could operate continuously for at least 45 hours without a drop in activity.
The wonderful improvements come from Nocera's recent discovery of several powerful，new and inexpensive catalysts. These catalysts make the energy transformation inside the leaf more efficient with water and sunlight. Right now，the new leaf is about 10 times more efficient at carrying out photosynthesis than a natural one. Besides，the device can run in whatever water is available；that is，it doesn't need pure water. This is important for some countries that don't have access to pure water.
With the goal to “make each home its own power station” and “give energy to the poor”，scientists believe that the new technology could be widely used in developing countries，especially in India and rural China.
【小题1】Which of the following orders correctly shows how the artificial leaf is used to produce electricity?
a．artificial leaves split water into hydrogen and oxygen
b．the hydrogen and oxygen gases are stored in a fuel cell
c．the artificial leaves are put in water
d．the fuel cell uses hydrogen and oxygen to produce electricity
| A．c，a，b，d | B．c，b，a，d |
| C．b，c，a，d | D．c，a，d，b |
| A．build up more power stations in the world |
| B．provide cheaper energy for developing countries |
| C．offer people in developing countries access to pure water |
| D．gain a deeper understanding of the photosynthesis process |
| A．an introduction to the history of artificial leaves |
| B．a mixture of water power and solar energy |
| C．giving energy to the poor |
| D．an invention copying photosynthesis |

“iPhone 5”, the tallest thing to happen to iPhone since iPhone
We don’t want to change your phone, we want to make you say, “Wow, that is a bigger change than I expected”. “iPhone 5” is a result of that desire to surprise.
It’s been completely redesigned. For the first time ever, we’ve increased the size of display (显示) by making the screen taller but not wider.
You can see more of your content without the need to scroll. We are making scrolling the thing of the past. It is more comfortable to use and reduces tiredness from scrolling when you read long documents.
Even with the larger display, it is the thinnest iPhone we ever built. To achieve the design this tall, we have to look at it and completely redesign the architecture inside. It’s 18% thinner and 79.5% taller than the previous iPhone. It makes everything you do on “iPhone5” easier. No more hidden menus, no confusing gestures. Everything is right at your fingertips.
The panorama feature (全景拍照) is simply awesome. The ultra HD (超高清) widescreen display lets you get your entire shot in a single snap (快门). You can also use its creative design for picture stabilization.
With an iPhone this tall, reception of signals has never been better. And of course, all your favorite applications are still available. In fact you will find your old favorites also benefit from the new experiencing handsome ultra HD widescreen. We found while many previous iPhone owners were using Facetime, they only used it for the faces. That’s why we are introducing Bodytime. With its ultra HD widescreen display, Bodytime lets you see a person’s entire body.
It took all of our learning and all of our thinking to realize something so simple, so clear, and yet so tall.
And I wish your pocket were tall enough to hold such a perfect invention!

(2013·高考福建卷，B)Your glasses may someday replace your smartphone，and some New Yorkers are ready for the switch.Some in the city can’t wait to try them on and use the maps and GPS that the futuristic eyewear is likely to include.
“ I’d use it if I were hanging out with friends at 3 a．m.and going to the bar and wanted to see what was open，”said Walter Choo,40，of Fort Greene.
The smartphonelike glasses will likely come out this year and cost between $250 and $600，the Times said，possibly including a variation of augmented(增强的) reality，a technology already available on smartphones and tablets (平板电脑) that overlays information onto the screen about one’s surroundings.So，for example，if you were walking down a street，indicators would pop_up showing you the nearest coffee shop or directions could be plotted out and come into view right on the sidewalk in front of you.
“As far as a mainstream consumer product，this just isn’t something anybody needs，”said Sam Biddle，who writes for Gizmodo.com.“ We’re accustomed to having one thing in our pocket to do all these things，”he added，“and the average consumer isn’t gonna be able to afford another device (装置) that’s hundreds and hundreds of dollars.”
9to5Google publisher Seth Weintraub，who has been reporting on the smartphonelike glasses since late last year，said he is confident that this type of wearable device will eventually be as common as smartphones.
“It’s just like smartphones 10 years ago，”Weintraub said.“A few people started getting emails on their phones，and people thought that was crazy.Same kind of thing.We see people bending their heads to look at their smartphones，and it’s unnatural，”he said.“ There’s gonna be improvements to that，and this a step there.”
【小题1】One of the possible functions of the smartphonelike glasses is to ________.
| A．program the opening hours of a bar |
| B．supply you with a picture of the future |
| C．provide information about your surroundings |
| D．update the maps and GPS in your smartphones |
| A．develop rapidly |
| B．get round quickly |
| C．appear immediately |

American researchers found females are the more talkative sex because of a special “language protein(蛋白质)” in the brain.
The study, conducted by neuroscientists (神经学家)and psychologist from the University of Maryland, concluded that women talked more because they had more of the Foxp2 protein. The research, published in the Journal of Neuroscience, found that higher levels were found among humans that were women but in rats that were males. Their findings came after it was previously claimed that ladies speak about 20,000 words a day – over 13,000 more than men. “This study is one of the first to report a sex difference in the expression of a language-associated protein in humans or animals,” said Prof Margaret McCarthy, who led the study. In their study, the researchers attempted to determine what might make male rats more vocal than their female friends.
They separated four-day-old rats from their mothers and then counted the number of times they cried out in the “ultrasonic range”, the frequencies higher than humans can hear, over five minutes. While both sexes called out hundreds of cries, the males called out twice as often, they found. But when the pups were returned to their mother’s cage, she fussed over her sons first. Tests conducted on the parts of the brain known to be associated with vocalcalls showed the male pups have up to twice as much Foxp2 protein as the females. The researchers then increased the production in the brains of female pups and reduced it in males. This led to the female rats crying out more often and their mothers showing more interest to them. In contrast, males became less “talkative”.
The researchers then tested samples from ten children, aged between three and five, which showed that females had up to 30 per cent more of the Foxp2 protein than males, in a brain area key to language in humans.
“Based on our observations, we assume higher levels of Foxp2 in girls and higher levels of Foxp2 in male rats is an indication that Foxp2 protein levels are associated with the more communicative sex,” said Prof McCarthy. “Our results imply Foxp2 as a component of the neurobiological basis of sex differences in vocal communication in mammals. “
【小题1】From the second paragraph, we can learn that ________.
| A．women always speak more words than men |
| B．men and male rats have low levels of language protein |
| C．women and male rats have similar levels of Foxp2 |
| D．McCarthy isn’t the first to find females more talkative |
| A．paid attention to | B．related to | C．put pressure on | D．counted on |
| A．test which part of the brain is key to language in rats and humans |
| B．prove the levels of Foxp2 protein in humans and rats are different |
| C．determine the reason why female rats are more talkative than male rats |
| D．discover the association between Foxp2 protein and vocal communication |
| A．Tests on humans and rats |
| B．Why women are the talkative sex |
| C．Sex differences in Foxp2 protein |
| D．Foxp2 protein determines oral ability |

As they migrate (迁移), butterflies and moths choose the winds they want to fly with, and they change their body positions if they start floating in the wrong direction. This new finding suggests that insects may employ some of the same methods that birds use for traveling long distances. Scientists have long thought that insects were simply at the mercy of the wind.
Fascinating as their skills of flight are, migrating behavior has been difficult to study in insects because many long distant trips happen thousands of feet above ground. Only recently have scientists developed technologies that can detect (测出) such little creatures at such great heights.
To their surprise, though, the insects weren’t passive travelers on the winds. In autumn, for example, most light winds blew from the east, but the insects somehow sought out ones that carried them south and they positioned themselves to navigate directly to their wintering homes.
Even in the spring, when most winds flowed northward, the insects didn’t always go with the flow. If breezes weren’t blowing in the exact direction they wanted to go, the insects changed their body positions to compensate (补偿). Many migrating birds do the same thing.
The study also found, butterflies and moths actively flew within the air streams that pushed them along. By adding flight speeds to wind speeds, the scientists calculated that butterflies and moths can travel as fast as 100 kilometers an hour. The findings may have real-world applications. With climate warming, migrating insects are growing in number. Knowing how and when these pests move could help when farmers decide when to spray their crops.
【小题1】What’s the main idea of the text?

Not long ago, people thought babies were not able to learn things until they were five or six months old. Yet doctors in the United States say babies begin learning on their first day of life.
Scientists note that babies are strongly influenced by their environment. They say a baby will smile if her mother does something the baby likes. A baby learns to get the best care possible by smiling to please her mother or other caregiver. This is how babies learn to connect and communicate with other human beings.
One study shows that babies can learn before they are born. The researchers placed a tape recorder on the stomach of a pregnant woman. Then, they played a recording of a short story. On the day the baby was born, the researchers attempted to find if he knew the sounds of the story repeated while in his mother. They did this by placing a device in the mouth of the newborn baby. The baby would hear the story if he moved his mouth one way. If the baby moved his mouth the other way, he would hear a different story. The researchers say the baby clearly liked the story he heard before he was born. They say the baby would move his mouth so he could hear the story again and again.
Another study shows how mothers can strongly influence social development and language skills in their children. Researchers studied the children from the age of one month to three years. The researchers attempted to measure the sensitivity of the mothers. The women were considered sensitive if they supported their children’s activities and did not interfere unnecessarily. They tested the children for thinking and language development when they were three years old. Also, the researchers observed the women for signs of depression.
The children of depressed women did not do as well in tests as the children of women who did not suffer from depression. The children of depressed women did poorly in tests of language skills and understanding what they hear.
These children also were less cooperative and had more problems dealing with other people. The researchers noted that the sensitivity of the mothers was important to the intelligence development of their children. Children did better when their mothers were caring, even when they suffered from depression.
【小题1】According to the passage, which of the following is NOT the factor that influences intelligence development in babies?
| A．The environment. | B．Mother’s sensitivity. |
| C．Their peers (同龄人) | D．Education before birth. |
| A．To prove that babies can learn before they are born. |
| B．To prove that babies can learn on the first day they are born. |
| C．To show mothers can strongly influence intelligence development in their babies. |
| D．To indicate early education has a deep effect on the babies’ language skills. |
| A．The children of depressed mothers who cared little for their children. |
| B．The children of women who did not suffer from depression. |
| C．The children of depressed but caring mothers. |
| D．Children with high communication abilities. |
| A．Scientific findings about how babies develop before birth. |
| B．Scientific findings about how the environment has an effect on babies’ intelligence. |
| C．A study shows babies are not able to learn things until they are rice or six months old. |
| D．Scientific findings about how intelligence develops in babies. |

Scientific experiments can sometimes go wrong and when they do the results may range from the disastrous to the troubling. One such experiment took place in South America about fifty years ago. Whether its final consequences will cause serious damage or nothing more than a small trouble still remains to be seen.
The story began in 1956 when an American scientist working in Brazil decided to solve the problem of increasing the productivity of that country’s bees. He imported a very active type of African bee from Tanzania and mated (交配)it with the more easy-going native variety to produce a new kind of bees. The new bees worked harder and produced twice as much honey. It seemed that Professor Kerr, for that was the scientist's name, had a total success on his hands.www.zxxk.com
Then things began to go wrong. For some reason as yet unseen, but perhaps as a result of something in their environment, the new bees began to develop extremely attacking personalities. They became bad-tempered and easy to be angry, attacked the native bees and drove them from their living places.
But worse was to follow. Having taken over the countryside, the new bees, with their dangerous stings (叮) , began to attack its neighbors -- cats, dogs, horses, chickens and finally man himself. A long period of terror began that has so far killed a great number of animals and about 150 human beings.
This would have been bad enough if the bees had stayed in Brazil. But now they are on the move, heading northwards in countless millions towards Central and North America, and moving at the alarming speed of 200 miles a year. The countries that lie in their path are naturally worried because it looks as if nothing can be done to stop them.
【小题1】 The results of the South American experiment .
| A．are not yet certain | B．have proved to be wrong |
| C．have caused a serious trouble | D．are not important |
| A．make African bees less active |
| B．make Brazilian bees more easy-going |
| C．increase the number of bees in Brazil |
| D．increase the amount of honey in Brazil |
| A．Their production of honey. | B．Their living environment. |
| C．Their hard work. | D．Their bad temper. |
| A．the bees have been driven to Central and North America |
| B．the bees must be stopped from moving north |
| C．the bees may bring about trouble in more countries |
| D．the bees prefer to live in Brazil |
