(2013·宜春五校聯(lián)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.
【小題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
【小題2】Besides milking cows,the robotic system also can ________.
A.a(chǎn)djust 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
【小題3】Why is the robotic system not popular now?
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.
【小題4】According to Doug,what is the wage of an employee per year?
A.$150,000~$175,000.
B.over $75,000.
C.$150,000~$30,000.
D.$30,000~$35,000.

Europe’s deadly outbreak of a rare form of E. coli bacteria (大腸桿菌) has brought new attention to food safety issues. One of the problems when people get sick from food is that the simplest question is often difficult or even impossible to answer. Just what did the people eat that made them sick?
Of course, one way to avoid these medical mysteries is to keep dangerous organisms out of the food supply. This is easier said than done, but scientists keep looking for new ways.
Scientists in the United States have developed an experimental system that uses a high-tech optical scanner. The system is designed to identify the presence of contaminants(致污物) like soil or animal waste on fresh produce. These can be sources of E. coli. E. coli bacteria naturally live in the intestines(腸) of humans and many animals. Most kinds of E. coli are harmless but some can make people sick.
The new scanner can also show damage and imperfections that might make the produce unappealing to shoppers.
Scientists designed the system at a Department of Agriculture research center in Beltsville, Maryland. Moon Kim of the Agricultural Research Service led the team.
MOON KIM: “We were requested, we were asked, to develop a method to detect contamination in produce. So we started with the apple as the model sample.”
The scanner uses a high-speed camera placed over the conveyer belt that moves the produce along. As the apples move along the belt, the scanner captures images of each piece of fruit.
Moon Kim says the team hopes the system will be available before long.
MOON KIM: “We are targeting for development in commercial plants for the next several years.”
The scanner can direct a sorting machine to separate the bad apples from the good ones. The system is currently able to show the surface of only half the apple as it speeds by. The inventers hope to improve the process so it can show the whole surface.
【小題1】What is the main topic of the text?

A.Bacteria. B.A high-tech scanner. C.A camera D.Food safety.
【小題2】E. coli bacteria ______.
A.broke out all over the world B.comes from soil or animal waste
C.is extremely harmful to health D.does not cause illness
【小題3】The high-tech scanner ______.
A.can help to sort out different fruits
B.make the produce appeal to shoppers
C.can only capture images of the whole apple
D.can identify the presence of contaminants
【小題4】What can be inferred from the text?
A.The scanner needs to be improved.
B.The scanner will be available in the next several years.
C.Moon Kim is unwilling to develop the scanner.
D.The scanner is connected to a sorting machine.

A machine which makes water out of air could become the greatest household invention since the microwave. Using the same technology as a dehumidifier (除濕器), the Water Mill is able to create a ready supply of drinking water by getting it from a limitless source-the air. The company behind the machine says not only does it offer all alterative to bottled water in developed countries,but it is a solution for the millions who face a daily water shortage.
The machine works by drawing in damp air through a filter(過濾器) and over a cooling element which changes it into water droplets.It can produce up to 12 liters a day.The Water Mill will also produce more water when storms pass over, as the humidity(濕度)in the air increases.In keeping with its ecodevelopment,the machine uses the same amount of electricity as three light bulbs.
Inventor Jonathan Ritchey said:“The demand for water is off the chart.People are looking for freedom from water distribution systems that are shaky and unreliable”.
The machine,which is about 3 feet wide,is likely to cost£800 when it goes on sale here in the spring.Its maker, Canadian firm Element Four, estimates that a liter of water will cost around 20 pence to produce.
Environmentalists claim half the world’s population will face water shortage because of climate change by 2080.One in five humans is said to lack access to safe drinking water.
The Water Mill is not effective in areas with below about 30 percent relative humidity, but with average relative humidity in England of more than 70 percent that won’t be much of an issue here.
【小題1】According to the author, the biggest advantage of the machine is its ______.

A.little power use B.unlimited source C.proper size D.high production
【小題2】We can conclude from the passage that the machine________.
A.can be used everywhere
B.has not been on sale
C.will replace the water distribution system
D.will solve the problem of water shortage
【小題3】The underlined phrase “off the chart” in the passage means ________
A.record-breaking. B.urgent. C.unbelievable. D.a(chǎn)mazing.
【小題4】What would be the best title for this passage?________
A.Microwave for Household Use B.Filter to Draw in Damp Air
C.Mode Dehumidifier on Sale D.Machine to Make Water out of Air

Today, when a fire breaks out, you can be sure a citizen with a cell-phone camera has posted it to Facebook or Twitter, or sent it to the media. But up to now, that citizen has not been able to easily send images and details of what is happening to the people who need it most: police, firefighters and building-security people who must respond, and whose ability to help is often measured in minutes, if not seconds.
That's about to change. A one-year old company called Elerts has developed a system that's designed to mobile and social technologies to speed the flow of information between citizens and emergency workers in time of danger. The system involves free mobile applications—iPhone and iPad app(應(yīng)用軟件)is available now—that eyewitnesses can use to report incidents and get public-safety warnings. And Elerts is offering a management console(控制臺)for security firms and universities to receive the reports and distribute warnings and instructions, like a map with the best evacuation route(疏散路線).
The service is the brainchild of Chris Russo, deputy fire chief in the coastal town of Hull, Mass. As mobile communications sped up, he grew increasingly frustrated by his inability to communicate effectively with colleagues and the public, particularly with people who are at the scene and might be able to provide help.
"Remembering situations when communications failed puts a pit in my stomach," Mr. Russo says. Last summer, he was in a search at a beach for a missing boy, who went into a bathhouse but didn't come out. First responders feared an abduction (綁架) on the beach or shark attack. The child's mother, who didn't speak English well, was so sad that she couldn't remember what color shorts he had on. Mr. Russo had no photo of the child, and no ability to turn to beachgoers.
Two long hours later, the boy was spotted by a low-flying helicopter lost and alone on the beach crying—a lucky break. "If 5 percent of beachgoers had an app to receive a message and send in sightings of a lost boy, the happy ending might have come much sooner," Mr. Russo said.
【小題1】What is the passage mainly about?

A.A moving story of Chris Russo.B.An app for reporting emergency.
C.A cell-phone instant service.D.An app for firm management.
【小題2】What does the underlined part in Paragraph 4 most probably mean?
A.Makes me feel frustrated.B.Causes a stomachache.
C.Arouses my interest.D.Leaves a hole in my stomach.
【小題3】We can infer from the passage that emergency workers ____.
A.have to carry out rescue work in minutes
B.must send images and details immediately
C.need images and detailed information badly
D.have to turn to Facebook and Twitter for details
【小題4】The author takes Chris Russo's experience as an example to ____.
A.a(chǎn)dvertise his creativity in communication
B.show readers the working principle of the new system
C.make the passage more interesting to read
D.inform readers how Russo got the idea of the service

BEIJING - By the end of 2011 China-made supercomputers will say goodbye to foreign microchips(微芯片) and start using their own "Chinese core(核心)", according to one of the country's leading scientists, Hu Weiwu.
Hu told reporters on Saturday that the "Dawning 6000" supercomputer, developed by the Institute of Computing Technology of CAS and the Dawning Information Industry Company (DIIC), will adopt Loongson microchips for the first time as its core parts. It will have a computing speed of more than 1,000 trillion operations a second.
Making supercomputers with Chinese microchips is one of the nation's major science and technology projects. Three organizations - the Institute of Computing Technology of CAS, Jiangnan Institute of Computing Technology and the National University of Defense Technology (NUDT) - have their own supercomputer projects.
According to their schedules, all three institutions will need to meet the target of using domestically(國內(nèi)的) developed microchips by the end of this year. Hu said the new supercomputer will use fewer than 10,000 Loongson microchips, and will also be more energy-efficient.
Tianhe-1A, developed by NUDT in Hunan's provincial capital Changsha, is the fastest supercomputer in the world. However, Tianhe-1A largely runs on 14,336 CPUs made by Intel, and 7,186 GPUs (processing units) from Nvidia, two US chip-makers.
Hu said there will be difficulties ahead as there is little affiliated equipment specially developed for these supercomputers. "We have enough supercomputers in China but still can't make full use of them," He said.
Hu added that although the China-made CPUs have improved since they were first produced in 2002, they have a long way to go to compete with US chip-makers such as Intel.
【小題1】What’s the best title for this passage?

A.The Arrival of Chinese Supercomputers
B.Homemade CPUs with a Long Way to Go
C.The Supercomputers of Three Organizations in China
D.Homemade CPUs on the Way for Local Supercomputers
【小題2】What will raise the speed to more than 1,000 trillion operations a second.?
A.Dawning 6000B.Loongson microchips
C.DIICD.Tianhe-1A
【小題3】What do we know about Tianhe-1A?
A. Not all the parts of Tianhe-1A are made by China.
B. Tianhe-1A is developed by CAS and DIIC.
C. Tianhe-1A will use fewer than 10,000 Loongson microchips.
D. NUDT has produced a most powerful supercomputer in China.
【小題4】The underlined word “affiliated” can be replaced by_______.

American researchers found females are the more talkative sex because of a special “l(fā)anguage protein(蛋白質(zhì))” in the brain.
The study, conducted by neuroscientists (神經(jīng)學(xué)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. “
【小題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
【小題2】The underlined phrase “fussed over” in the third paragraph probably means______.
A.paid attention toB.related toC.put pressure onD.counted on
【小題3】The researchers carried out the experiments on rats in order to _______.
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
【小題4】Which of the following can be the best title for the passage ?
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

Yawning sends out certain messages -either “Oh ,this movie is so boring” or “I probably need to get some sleep”. But did you know that a yawn can also help your brain to cool down when it is overheated?
A new study, led by a research team at Princeton University, has indicated that yawning could be the brain’s natural way of regulating temperature. People yawn more often when the temperature outdoors is lower than their body temperature but are less likely to yawn when it is hotter outdoors, according to Sciencedaily. com.
The research team did an experiment on 160 people, 80 in summer and 80 in winter, to examine how often they yawned at different air temperatures. The study found that people yawned more often in winter than in summer. Scientists say that when the air temperature is lower outside the body, there is heat exchange between the overheated brain and the cool air. But when the air temperature is higher than or equal to the body, people are less likely to yawn because the hot air they breathe in will make the brain even hotter.
When people yawn, their jaw is also stretched ,which increases blood flow and may also help cool the brain
The study showed that the amount someone yawned could be related to the amount of time they spent outside. The longer they spent outside in summer, the less they yawned. Nearly 40 percent of participants yawned within their first five minutes outside, but after that the percentage was reduced to less than 10 percent.
However, the result was the opposite in winter. The number of people who yawned increased when they spent more than five minutes outdoors. But the change was only slight compared to summertime.
According to Gallup, this is the first report to show that yawning frequencies change depending on season. This could help us to understand better the way our brains work. It may also help us understand the reason why frequent yawning can sometimes be a sign of brain disease.
【小題1】The purpose of the experiment is ______.

A. to prove people yawn in winter and in summer equally
B. to indicate brain can regulate temperature naturally
C. to find the frequency of people’s yawning
D. to show the real reason why people yawn
【小題2】The information we get from Paragraphs 5 and 6 is that ______.
A. longer outdoor summertime results in more yawns
B. yawning frequency changes with outdoor time
C. yawning frequency increases with outdoor time
D. longer outdoor wintertime leads to fewer yawns
【小題3】Acorrding to the text ,people yawn more often ______.
A,  when the air temperature is lower outside the body
B.  when the hot air breathed in makes the brain hotter
C. when the air temperature is higher than the body
D. when the air temperature is equal to the body
【小題4】What could be the best title for the text?
A. Yawning Is A Sign of Brain Disease
B. Yawning Carries Some Information
C. Yawning Benefits Your Body
D. Yawning Cools Your Brain

In the new book The Education of Millionaires,Michael Ellsberg suggests that although“there are many wonderful things you can learn in college,”few of them are applied to real life .So Ellsberg has written the book to tell“the capabilities and attitudes that will get you improved outside the classroom.”
I welcome the kind of debate about the value of higher education.It is necessary to remember, however,that Ellsberg also tells how important it is to make money.He mentions a number of college dropouts一such as Bill Gates and Michael Dell一to show how successful they have become without the benefit of a college degree.While Ellsberg stresses the achievements of dropouts,he includes degree holders who have become wealthy and famous.For example,of the current Fortune 500 CEOs,some 99%have a college degree.Similarly,of the Forbes 400 richest people in America,81%hold postseconda.ry(高等)degrees.
But in the discussion,what is forgotten about the value is that the purpose of education is not simply to enable one to earn a living but to prepare one for living over the course of life .What is also left out of the debate about higher education is that its purpose is not just to provide a pathway covered with gold for the nation’s elites(精英).If we have the discussion that way,we may look down upon the people who devote themselves to other ordinary jobs that form the basic structures(結(jié)構(gòu))of our society,Though these individuals may not be reaching for the kind of stars that Michael Ellsberg and others would have them grasp,most are doing something even more important:they are involved in the useful tasks of good citizens and contributing to the common welfare,including providing for their families.
【小題1】In the book The Education of Millionaires,Michael Ellsberg___.

A.a(chǎn)pproves of the value of education
B.explains the reasons for dropping out
C.tells the way of getting out of college
D.discusses the practical value of college degrees
【小題2】The second paragraph suggests a fact that____
A.the value of higher education is never challenged
B.higher education ensures people making more money
C.most of the richest people received college education
D.success of dropouts proves the value of higher education
【小題3】From the last paragraph we can learn that the author___
A.is keen on society charity work B.calls for the equality of all man
C.speaks highly of the nation’s elites D.shows respect to common people
【小題4】The passage is written mainly to.___

(2013·高考北京卷,D)People who multitask all the time may be the worst at doing two things at once,a new research suggests.The findings,based on performances and self­evaluations by about 275 college students,indicate that many people multitask not out of a desire to increase productivity,but because they are easily distracted (分心) and can’t focus on one activity.And “those people turn out to be the worst at handling different things,”said David Sanbonmatsu,a psychologist at the University of Utah.
Sanbonmatsu and his colleagues gave the students a set of tests and asked them to report how often they multitasked,how good they thought they were at it,and how sensation­seeking (尋求刺激) or impulsive (沖動(dòng))they were.They then evaluated the participants’multitasking ability with a tricky mental task that required the students to do simple mathematical calculations while remembering a set of letters.
Not surprisingly,the scientists said,most people thought they were better than average at multitasking,and those who thought they were better at it were more likely to report using a cellphone while driving or viewing multiple kinds of media at once.But those who frequently deal with many things at the same time were found to perform the worst at the actual multitasking test.They also were more likely to admit to sensation­seeking and impulsive behavior,which connects with how easily people get bored and distracted.
“People multitask not because it’s going to lead to greater productivity,but because they’re distractible,and they get sucked into things that are not as important,”Sanbonmatsu said.
Adam Gazzaley,a researcher at the University of California,San Francisco,who was not a member of the research group,said one limitation of the study was that it couldn’t find out whether people who start out less focused tend toward multitasking or whether people’s recognizing and understanding abilities change as a result of multitasking.
The findings do suggest,however,why the sensation­seekers who multitask the most may enjoy risky distracted driving.“People who are multitasking are generally less sensitive to risky situations.”said Paul Atchley,another researcher not in the group.“This may partly explain why people go in for these situations even though they’re dangerous.”
【小題1】The research led by Sanbonmatsu indicates that people who multitask________.

A.seek high productivity constantly
B.prefer handling different things when getting bored
C.a(chǎn)re more focused when doing many things at a time
D.have the poorest results in doing various things at the same time
【小題2】When Sanbonmatsu and his colleagues conducted their research,they________.
A.a(chǎn)ssessed the multitasking ability of the students
B.evaluated the academic achievements of the students
C.a(chǎn)nalyzed the effects of the participants’tricky mental
tasks
D.measured the changes of the students’understanding ability
【小題3】According to Sanbonmatsu,people multitask because of their________.
A.limited power in calculation
B.interests in doing things differently
C.inability to concentrate on one task
D.impulsive desire to try new things
【小題4】From the last paragraph,we can learn that multitaskers usually________.
A.drive very skillfully
B.go in for difficult tasks
C.fail to react quickly to potential dangers
D.refuse to explain the reasons for their behavior

(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(收縮) 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(掃描儀) 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.”
【小題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.
【小題2】The study was carried out by analyzing________.
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
【小題3】Which of the following is closest in meaning to“mechanism” in Paragraph 6?
A.Order. B.System.
C.Machine. D.Treatment.
【小題4】This study may contribute to________.
A.treating anxiety and stress better
B.explaining the cycle of fear and anxiety
C.finding the key to the heart­brain communication
