Deputy Agriculture Secretary Kathleen Merrigan sees an epidemic (流行病) sweeping across Americas farmland. It has little to do with the usual challenges, such as flood, rising fuel prices and crop-eating insects. The country's farmers are getting older, and there are fewer people standing in line to take their place. National agricultural census (普查) figures show that the fastest-growing group of farmers is the part over 65. Merrigan is afraid the average age will be even higher when the 2012 statistics are completed.
Merrigan, a former college professor, is making stops at universities across the country in hopes of encouraging more students to think about careers in agriculture. Aside from trying to stop the graying of America's farmers, her work is made tougher by a recent blog posting that put agriculture at No.1 on a list of "useless" college degrees. Top federal agriculture officials are talking about the posting, and it has the attention of agricultural organizations across the country.
“There couldn't be anything that's more incorrect," Merrigan said. "We know that there aren't enough qualified graduates to fill the jobs that are out there in American agriculture.
In addition, a growing world population that some experts predict will require 70% more food production by 2050, she said.
“I truly believe we're at a golden age of agriculture. Global demand is at an all-time record high, and global supplies are at all-time record lows," said Matt Rush, director of the Texas Farm Bureau. "Production costs are going to be valuable enough that younger people are going to have the opportunity to be involved in agriculture”.
The Department of Agriculture has programs aimed at developing more farmers and at increasing interest in locally grown food. The National Young Farmers' Coalition has also been pushing for state and federal policy changes to make it easier for new fermers.
Ryan Best, president of Future Fanners of America, has been living out of a suitcase, traveling the country and visiting with high school students about careers in agriculture. The 21 -year-old Best hopes his message-that this is a new time in agriculture-will motivate the next generation to turn around the statistics.“Never before have we had the innovations (創(chuàng)新）in technology which have led to agriculture in this country being the most efficient it has ever been” he said. “There’s really a place for everybody to fit in”
小題1:What is the new challenge to American agriculture?

When Geoff Marcy was 14, his parents bought him a telescope. Every night, he would go onto the roof outside his window to see the wonders of the sky.
“What excited me most was whether there were planets in other solar systems where life might exist,” he says. “I decided to try to find planets orbiting other stars like our Sun.”
And he did. “My fellow researcher, Paul Butler, and I found our first planet in 1995,” Dr. Marcy says. “We worked for ten years without finding anything! But we stuck with it and our patience paid off.”
Since then, the two scientists have discovered 65 of the more than 100 planets found orbiting other stars. Dr. Marcy and Dr. Butler also spotted the first “family” of three planets. In June 2002 they announced another discovery: a Jupiter-like planet orbiting star 55Cancri.
At first, the two researchers found only planets that orbit close to stars. Recently, the scientists found planets farther out. The planet orbiting 55Cancri is a major breakthrough: it is the first sighting of a large gas planet about same distance from the star as Jupiter is from the Sun.
Why is this important ? Scientists think that life on Earth may exist because of two special features in our solar system. The first is Jupiter.
“Because it’s so big, Jupiter pulls comets and asteroids(小行星), or they all come and hit the Earth.” Dr. Marcy explains. “Without Jupiter , life on Earth would likely have been destroyed.”
A second feature is that Earth is a rocky planet where liquid water, which is necessary for life , can exist. Unlike gas planets, rocky planets like Earth have surfaces where water can gather in pools and seas, which may support life. A huge space exists between the Jupiter-like planet and two other planets that lie close to 55Cancri. Is there an Earth-like planet in the space, too small for us to notice? If so, says Dr. Marcy, “We would have two striking similarities to our solar system: a Jupiter-like planet and an Earth-like planet. And there may be life!”
小題1:What can we learn about Dr. Marcy from the passage?
A．He is fond of watching Jupiter.
B．He is from a scientist family.
C．He dislikes working with Paul Butler.
D．He is interested in finding life in outer space.
小題2:Which of the following is true of the recent discovery?
A．The planet is not as protective as Jupiter.
B．The planet is close to star 55Cancri.
C．The planet proves to be a gas planet.
D．The planet is as large as Jupiter.
小題3:Dr. Marcy and Dr. Butler began to find new planets in ____.
A．1995B．1985C．2002D．1981
小題4:Dr. Marcy thinks that life may exist in the 55Cancri system because ____.
A．he has found the system similar to the solar system.
B．he has discovered an Earth-like planet there.
C．he has discovered a rocky planet there.
D．he has found signs of life in the system
小題5:“But we stuck with it”( in Paragraph 3) means ____.
A．they felt discouragedB．they carried on with it
C．they failed in their attemptD．they made some progress

Ever wonder how much a cloud weighs? What about a hurricane? A meteorologist(氣象學(xué)者) has done some estimates and the results might surprise you.
Let's start with a very simple white puffy cloud — a cumulus cloud（積云）. How much does the water in a cumulus cloud weigh? Peggy LeMone, senior scientist at the National Center for Atmospheric Research in Boulder, Colorado, did the numbers. "The water in the little cloud weighs about 550 tons," she calculates. "Or if you want to convert it to something that might be a little more meaningful … think of elephants."
The thought of a hundred elephants-worth of water suspended(懸浮的) in the sky begs another question — what keeps it up there?
"First of all, the water isn't in elephant-sized particles（微粒）, it's in tiny tiny tiny particles," explains LeMone. And those particles float on the warmer air that's rising below. But still, the concept of so much water floating in the sky was surprising even to a meteorologist like LeMone. "I had no idea how much a cloud would weigh, actually, when I started the calculations," she says.
So how many elephant units of water are inside a big storm cloud—10 times bigger all the way around than the "puffy" cumulus cloud? Again, LeMone did the numbers: About 200,000 elephants.
Now, ratchet up(略微調(diào)高) the calculations for a hurricane about the size of Missouri and the figures get really massive(巨大的). "What we're doing is weighing the water in one cubic meter theoretically pulled from a cloud and then multiplying by(乘上) the number of meters in a whole hurricane," she explains.
The result? Forty million elephants. That means the water in one hurricane weighs more than all the elephants on the planet. Perhaps even more than all the elephants that have ever lived on the planet.
小題1:The weight of      is NOT mentioned in the passage.
A．a(chǎn) cumulus cloudB．a(chǎn) tornado
C．a(chǎn) hurricaneD．a(chǎn) storm cloud
小題2:How did Peggy LeMone feel about the result of her calculations?
A．She found it not convincing.
B．She thought it needed further calculations.
C．She was quite surprised at it.
D．She considered the calculations inaccurate.
小題3:What can be inferred from the passage?
A．A storm cloud weighs about 200,000 elephants.
B．The water in a hurricane weighs more than that in any other kind of cloud.
C．There are less than forty million elephants living on the earth.
D．The water in the cloud is in very tiny partials.
小題4:What is the best title for the passage?
A．How Much a Cloud WeighsB．How Much a Hurricane Weighs
C．Surprising ResultsD．Elephants in the Sky

The bedroom door opened and a light went on, signaling an end to nap time．The toddle（初學(xué)走路的嬰兒）, sleepy-eyed, clambered to a swinging stand in his crib．He smiled, reached out to his father, and uttered what is fast becoming the cry of his generation: "iPhone!"
Just as adults have a hard time putting down their iPhones, so the device is now the Toy of Choice for many 1-, 2- and 3-year-olds．The phenomenon is attracting the attention and concern of some childhood development specialists．
Natasha Sykes, a mother of two in Atlanta, remembers the first time her daughter, Kelsey, now 3 but then barely 2 years old, held her husband's iPhone．"She pressed the button and it lit up．I just remember her eyes．It was like 'Whoa!' "The parents were charmed by their daughter's fascination．But then, said Ms．Sykes （herself a Black Berry user）, "She got serious about the phone．" Kelsey would ask for it．Then she'd cry for it．"It was like she'd always want the phone," Ms．Sykes said．
Apple, the iPhone's designer and manufacturer, has built its success on machines so user-friendly that even technologically blinded adults can figure out how to work them, so it makes sense that sophisticated children would follow．Tap a picture on the screen and something happens．What could be more fun?
The sleepy-eyed toddler who called for the iPhone is one of hundreds of iPhone-loving toddlers whose parents are often proud of their offspring's ability to slide fat fingers across the gadget's screen and pull up photographs of their choice．
Many iPhone apps on the market are aimed directly at preschoolers, many of them labeled "educational," such as Toddler Teasers: Shapes, which asks the child to tap a circle or square or triangle; and Pocket Zoo, which streams live video of animals at zoos around the world．
Along with fears about dropping and damage, however, many parents sharing iPhones with their young ones feel guilty．They wonder whether it is indeed an educational tool, or a passive amusement like television．The American Academy of Pediatrics is continually reassessing its guidelines to address new forms of "screen time．" Dr．Gwenn Schurgin O'Keeffe, a member of the academy's council, said, "We always try to throw in the latest technology, but the cellphone industry is becoming so complex that we always come back to the table and wonder- Should we have a specific guideline for them?"
Tovah P. Klein, the director of a research center for Toddler Development worries that fixation on the iPhone screen every time a child is out with parents will limit the child's ability to experience the wider world.
As with TV in earlier generations, the world is increasingly divided into those parents who do allow iPhone use and those who don't. A recent post on UrbanBaby.com, asked if anyone had found that their child was more interested in playing with their iPhone than with real toys. The Don't mothers said on the Website: "We don't let our toddler touch our iPhones ... it takes away from creative play." "Please ... just say no. It is not too hard to distract a toddler with, say ... a book."
Kathy Hirsh-Pasek, a psychology professor who specializes in early language development, sides with the Don'ts. Research shows that children learn best through activities that help them adapt to the particular situation at hand and interacting with a screen doesn't qualify, she said.
Still, Dr. Hirsh-Pasek, struck on a recent visit to New York City by how many parents were handing over their iPhones to their little children in the subway, said she understands the impulse (沖動(dòng)). "This is a magical phone," she said. "I must admit I'm addicted to this phone."
小題1:The first paragraph in the passage intends to ______.
A．get us to know a cute sleepy-eyed child in a family
B．show us how harmful the iPhone is
C．lead us to the topic of the toddlers' iPhone-addict
D．explain how iPhone appeals to toddlers
小題2:According to the author, iPhones are popular with both adults and young kids because they are______.

One is never too old to learn. Life learning (sometimes called un-schooling or self-directed learning) is one of those concepts that are almost easier to explain by saying what it isn’t than what it is. And that’s probably because our own schooled backgrounds have convinced us that learning happens only in a fine building on certain days, between certain hours, and managed by a specially trained professional.
Within that schooling framestudy, no matter how hard teachers try and no matter how good their textbooks, many bright students get bored, many slower students struggle and give up or lose their self-respect, and most of them reach the end of the process unprepared to enter into society. They have memorized a certain body of knowledge long enough to rush back the information on tests, but they haven’t really learnt much, at least of the official curriculum.
Life learners, on the other hand, know that learning is not difficult, that people learn things quite easily if they’re not compelled and forced, if they see a need to learn something, and if they are trusted and respected enough to learn it on their own timetable, at their own speed, in their own way—no matter what age and no matter whether we’re at school or at home.
Life learning is independent of time, location or the presence of teacher. It does not require mom or dad to teach, or kids to work in workbooks at the table from 9 to noon. Life learning is learner-driven. It involves living and learning—in and from the real world. It is about exploring, questioning, experimenting, making messes, taking risks without fear of making mistakes, being laughed at and trying again.
Furthermore, life learning is about trusting kids to learn what they need to know and about helping them to learn and grow in their own ways. It is about providing positive experiences that enable children to understand the world and their culture and to interact with it.
小題1:It is implied in the text that it is hard to ______.
A．tell the nature of life learning 　　B．carry life learning through
C．learn without going to school 　　D．find a specially trained teacher
小題2:According to the author, the schooling framestudy often ______.
A．produces slow students with poor memories
B．ignores some parts of the official curriculum
C．fails to provide enough knowledge about life
D．gives little care to the quality of teaching materials
小題3:Life learners recognize that learning will not be difficult if they are ______.
A．a(chǎn)ble to respect other people　B．careful to make a time table
C．clear about why to learn　　D．cautious about any mistakes
小題4:According to the author, life learning ______.
A．could prevent one from running risks
B．teaches a kid how to avoid being laughed at
C．makes a kid independent of his parents
D．could be a road full of trials and errors
小題5:Through life learning, children ______.
A．will grow without the assistance from parents
B．will be seperated from the negative side of society
C．will be driven to learn necessary life knowledge
D．will learn to communicate with the real society

What exactly is intelligence? There aren’t any easy answers．Despite the progress that has been made in genetics and psychology, human intelligence has remained one of the most controversial areas of modern science，until now, that is, for the discovery of a gene linked to intelligence has made the experts think again．
Robert Plomin of the Institute of Psychiatry in London and his colleagues in the US have been looking into genetic make-up．From their research, they have discovered that a slightly different gene is more common in those with a high IQ．Plomin analyzed DNA from two groups of 51 children aged between 6 and 15．What he found was that the first group had an IQ of 136, putting them in the top 5% of the population, while the other group had an average IQ of 103．An analysis of their genes showed that 32% of children in the higher group had the gene in question, while only 16% in the second group did．However, there is a lot more research to be done, and Plomin himself is cautious at this early stage．He suggests that there are probably many genes that contribute to intelligence, rather than just one. Several studies have shown a strong link between IQ and career success, although some psychologists remain unconvinced about this．Professor Michael Rowe, who has written a book called Genius Explained, is one of these．“The people with the highest IQs are not usually the ones who do best in their careers．”
Many psychologists now believe that when it comes to intelligence, IQ isn’t everything．Many alternative views have been put forward recently．One example is the idea of multiple intelligences, which was developed in the 1980s by Harvard psychologist Howard Gardner．This offers a much broader view than the IQ theory, including creativity and communication skills as relevant factors in intelligence．
Tony Buzan, brain expert and author of Master your Memory, is enthusiastic about this belief, arguing that true geniuses do indeed appear to combine high levels of each type of intelligence．He lists Alexander the Great, Pablo Picasso and Albert Einstein as examples．At the same time, Buzan believes that everyone can develop their intelligence, only if they take the trouble to exercise their brain．Perhaps there’s hope for us all!
小題1:What does the underlined word “This” in Paragraph 3 refer to?
A．The development of intelligence
B．The idea of multiple intelligences
C．IQ isn’t everything for intelligence
D．Alternative views have been put forward
小題2:Why does the author use data in Paragraph 2?
A．To make a suggestion．B．To draw a conclusion
C．To prove an idea．D．To give an example
小題3:What can we learn from the passage?
A．Robert Plomin confirms genes have something in common
B．Howard Gardner thinks intelligence includes various factors
C．Michael Rowe approves of a strong link between IQ and career
D．Tony Buzan agrees geniuses exercise brain to improve intelligence
小題4:What might be the best title of the passage?
A．The relationship between genes and intelligence
B．IQ benefits a lot from high intelligence

Can a fish hear fishermen moving along the stream? What are the facts about the ability of a fish to see? Can they tell the difference between colors?
The sharp hearing of a fish has been proved by two scientists, who trained a fish to expect its food when it heard the sound of a whistle. And a slight sound two hundred feet away could drive fishes away. That should make fishermen start thinking.
One scientist had made experiments to prove fish can recognize different colors such as red, brown, yellow and green.
Fish also have an eye for different shapes. One scientist proved this by teaching fish to connect certain patterns with food. He used a small circle and a square. If the fish swam towards the circle, they received food as a reward. If they swam towards the square, they received nothing. The fish learned in time to go to the circle but not to the square. Does this mean that in time fish might learn to leave alone all food on hooks that they have seen often before? Here is something for all fishermen to think about!
These facts help to make more believable some of the “believe it or not” stories that have been told about fish. It is clear that fish have sometimes shown their ability to gain knowledge as man does. A good example of what we might call “thinking” by a fish is given by an experience of Dr. Andrew Gage. Fishing over a bridge, he hooked a fish. It struggled and dragged the line two hundred feet away before he stopped it. Then it swam back to the bridge. The clever fish then swam round a pile and, with a sudden push, broke the line. If the story ended there, one could say that the fish had freed itself by chance. However, Gage went on fishing. Below him he could see the fish that had broken loose. After another twenty minutes the fish again seized the food on the hook. This time it did not swim out but swam round one of the piles and again broke the line.
Many stories are told of the fish that get away and the clever “old hand” ones that can’t be caught. The more often a fish is nearly caught, the more difficult it will be to interest it next time.
小題1:The last two paragraph’s mainly discuss _________.
A．whether a fish can think as man does
B．how a fish could escape from danger
C．how to catch a fish more easily
D．whether a fish is believable
小題2: What’s the best title of the passage?
A．Fish can hear and see
B．How clever is a fish?
C．Fish can play tricks
D．How scientists help fishermen.
小題3:We can infer from the last paragraph that _________.
A．it’s difficult to catch fish;
B．fish are cleverer sometimes than fishermen
C．fish seem to learn by their experience
D．fewer people will be interested in fish

Risk of death is 3.5 t0 5 times greater for obese smokers than it is for people who have never smoked and are at a normal weight, according to a study published in the November, 2006 issue of the American Journal of Preventive Medicine.
The study, which began with a self-administered questionnaire taken between 1983 and 1989, asked more than 80,000 radiologic technologists aged 22 t0 92 questions about age, height, weight and smoking behavior.
BMI (body mass index) was calculated, with a BMI of 30 t0 34.9 being considered obese, and 35 and over being very obese. Smoking behavior was analyzed by looking at a person's tobacco consumption level, number of years smoked, and current smoking status. Researchers then followed participants through December of 2002, noting the number of deaths that occurred.
The study involved researchers from the National Cancer Institute, the University of Minnesota and the American Registry of Radiolegic Technologists.
Key Findings:
20 percent of obese adults in the United States smoke.
Obese smokers face a greater risk of death from cancer and circulatory disease.
Current smoking is a greater risk factor for death by cancer than obesity is, generally speaking.
The higher a person's pack-years (number of packs smoked per day times the number of years smoked) are, the greater the risk of death.
Men and women of all ages faced an elevated risk of death due to circulatory disease as BMI increased. And for those who were both obese and currently smoking, risk of circulatory disease increased 6 to 11 times under the age of 65, as compared to their never-smoking, normal weight counterparts.
While it's not surprising that obesity coupled with smoking is a recipe for trouble, it is important to highlight this growing health concern in America today.
Taking Charge of Your Health
Making healthy choices can be difficult when we're constantly bombarded with products that are hazardous to our health, but it's not impossible. With education and some motivation, we all have the ability to make lasting changes for the better. If you're an overweight smoker worried about gaining weight due to quitting, take heart. It's never too late to change your course and even reverse damage to some extent.
小題1:What is the probably the best title of the text?

Multitasking
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 self-evaluation 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 sensation-seeking (尋求刺激) or imperative (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 sensation-seeking 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   toward multitasking or whether people’s recognizing and understanding abilities change as a result of multitasking.
The findings do suggest, however, why the sensation-seeker 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 calculationB．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 different tasks
C．fail to react quickly to potential dangers
D．refuse to explain the reasons for their behavior
