    More than 30 million kids buy school lunch each day. This year, many schools raised lunch prices to fight raising costs. Students pay about $2 a meal now. That is 27 cents more than last year. But they still get a good deal. The average cost for schools to produce one meal has gone up 30 cents, and is now $3. 
    So, how do schools neither make money nor lose money? To start, the government pays for a small part of the difference. Schools have to make up the rest. Peggy Eller, a leader of school nutrition (营养) service in Hudson, Wisconsin, said her district is cutting costs by using fewer paper products and serving smaller portion(份额). Well, portion control is one key to healthful eating! 
    The push for more healthful food has grown in recent years. One in five kids aged 6 to 19 is overweight. Being overweight can cause health problems. Many states passed laws that require schools to serve nutritious meals. 
    Since 2004, more than 90% of all U.S. Schools have removed the fat from lunches. Foods high in fat, salt and sugar have been replaced by low-fat milk, fresh fruits and vegetables. These new items on lunch menus have encouraged kids to change their eating habits. “It makes easier to try new things at home, “said Savanna Mackey, a Florida fifth-grader.  
    Students need healthful meals to grow strong and do well in school. “Rising prices won’t stand in the way,”says school nutritionist Jane Thornton. “We’ll just be more clever in how we do things.”
    小题1:In the first paragraph, the author aims to tell us        .
    A．the large number of kids buying school lunch
    B．the average price of school lunch
    C．the school's ways to deal with school lunch
    D．the fact of school lunch's getting more expensive
    小题2:Many school districts raised lunch prices because        .
    A．there is less healthful food on the menus
    B．the cost of food has gone up
    C．kids often forget to bring lunch money
    D．some school dining-halls are serving smaller portions
    小题3:According to Paragraph 4, Savanna Mackey      .
    A．doesn't like the new items on the lunch menus
    B．always enjoys foods like fresh and vegetables
    C．becomes interested in eating healthy food at home
    D．prefers eating at school to eating at home
    小题4:What can be inferred from the passage?
    A．American schools solve the problem of high food prices by themselves.
    B．American schools are very concerned about their students’ health.
    C．Almost all schools are forced by the government to serve healthy foods.
    D．American childhood overweight is mainly caused by the present lunch foods.

    Have you ever seen any students whose trousers hang so low that you can see their underwear? What do you think of that? Fashionable? Some of today’s teenagers are big fans of such a look. But recently this trend has been at the center of an argument in Italian middle schools. The headmaster of a school in central Italy has asked students to stop wearing low-rise jeans that expose underwear and parts of the body. His request came after a class trip, when he saw one boy's baggy trousers slide to his feet. He pointed out that this way of dressing is not suitable for school. But in Italy, a nation that takes fashion very seriously, the suggestion caused a debate among parents, teachers and students. The issue is whether the headmaster's request will limit students' freedom— or whether dress in Italian schools is too casual. A parents' group praised the move in favor of good taste, while others advised schools to stop worrying about fashion and fix up old school buildings. “We do not want to kick fashion out,” the headmaster explained, “but extremes of fashion like this are not right in school.” Many other schools have now requested that their students also stop wearing such trousers. Most students have simply ignored the request. Ludovica Gaudio, 14, wore extremely low trousers exposing orange underwear in class. It was cold, so she wore a matching orange scarf. Another 14-year-old said she would probably respect the request, simply for practical reasons. “I don't really feel comfortable in those sort of jeans，” said Sarah Lattanzi, “in winter, when dressed like that, it's quite cold and I am afraid my stomach will ache.”
    小题1:What led to the argument in Italian middle schools？______
    A．Students' craze for fashions.B．Clothes that are too exposing.
    C．Students' ignoring dress codes.（规则）D．Students' underwear.
    小题2:Which of the following supports the headmaster's request?___
    A．Fashion should be taken seriously.
    B．Fashion should not be followed in school.
    C．Students should have their freedom in choosing what they wear.
    D．Students should be encouraged to have good taste in clothes.
    小题3: The argument against the headmaster's request is that ______.
    A．dress in Italian schools is too casual
    B．fashion should not be followed in school
    C．schools should pay attention to things more important than students' clothes
    D．low-rise jeans can do harm to youngster's health
    小题4:The purpose of this story is to ________
    A．show Chinese students that wearing very fashionable clothes in school is under attack in other countries, too.
    B．show that dress code is necessary even in a country like Italy
    C．let us see that Italian students react differently to schools' requests.
    D．tell us that a debate started in Italian middle schools over the way students dress in School

    Teachers and parents usually pay attention to the pictures when they read storybooks to preschool children. But a new study suggests that paying attention to the words and letters on the page may lead to better readers.
    The two-year study compared children who were read to this way in class with children who were not. Those whose teachers most often discussed the print showed clearly higher skills in reading, spelling and understanding. These results were found one year and even two years later.
    Shayne Piasta, an assistant professor of teaching and learning at Ohio State University, was an author of the study. She says most preschool teachers would find this method manageable and would need only a small change in the way they teach. They already read storybooks in class. The only difference would be increased attention to the printed text.
    Ms Piasta says if you get children to pay attention to letters and words, it makes sense that they will do better at word recognition and spelling. But she says research suggests that very few parents and teachers do this in a systematic(系统的) way.
    More than 300 children aged four and five were observed in classrooms in Ohio and Virginia. The children came from poor families and were below average in their language skills. This put them at risk of reading problems later. For 30 weeks, the children took part in a program called Project STAR. It tests the short-term and long-term results of reading regularly to preschool children in their classrooms.
    There’re different ways that adults can talk to children about print. They can point to a letter and discuss it, and even trace the shape with a finger. They can point out a word, “This is a ‘dog’.” They can discuss how the words tell the story. And they can talk about the organization of the print—for example, showing how words are written left to right in English.
    小题1:According to the text, Shayne Piasta _______.
    A．worked in a middle school
    B．didn’t attend the research at all
    C．liked kids to be educated through words
    D．hoped to increase kids’ interest through pictures
    小题2:According to the text, Project STAR ____.
    A．focused on adults’ education
    B．was to study reading results
    C．was mainly conducted at home
    D．tested kids with good reading skills
    小题3:What is the last paragraph mainly about?
    A．Why words have meanings.
    B．Different expressions of words.
    C．How words are spelled differently.
    D．Ways of teaching about print.
    小题4: The text may appear in ____.
    A．Child Development
    B．Daily Technology
    C．International Affairs
    D．Health Development

    About ten men in every hundred suffer from color blindness in some way. Women are luckier, only about one in two hundred is affected in this matter. Perhaps, after all, it is safer to be driven by a woman!
    There are different forms of color blindness. In some cases a man can not see deep red. He may think that red, orange and yellow are all shades of green. Sometimes a person cannot tell the difference between blue and green. In rare cases an unlucky man may see everything in shades of green - a strange world indeed.
    Color blindness in human beings is a strange thing to explain. In a single eye there are millions of very small things called “cones”. These help us to see in a bright light and to tell difference between colors. There are also millions of “rods” but these are used for seeing when it is nearly dark. They show us shape but no color.
    Some insects have favorite colors. Mosquitoes (蚊子) like blue but do not like yellow. A red light will not attract insects, but a blue lamp will. In a similar way human beings also have favorite colors. Yet we are lucky. With the aid of the cones in our eyes we can see many beautiful colors by day, and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible (看不见的) colors around.
    小题1:Why do some people say it is safer to be driven by women?
    A．Women are more careful.
    B．There are few color-blind women.
    C．Women are fonder of driving than men.
    D．Women are weaker but quicker in thinking
    小题2:This passage is mainly about ________.
    A．color and its surprising effects
    B．women being luckier than men
    C．danger caused by color blindness
    D．color blindness
    小题3:According to the passage, with the help of the “cones”， we can ________.
    A．tell orange from yellow
    B．see in weak light
    C．kill mosquitoes
    D．tell different shapes
    小题4:We can attract and kill mosquitoes by using a ________.
    A．red lightB．yellow lightC．blue lightD．green light

    Every English learner hopes to find a patient native speaker who will politely correct mistakes and teach him some useful new vocabulary. But native speakers can be hard to find. If you’re having trouble communicating in English, American situation comedies are one good way to help.
    They can not only give you a lot of information about American culture, but also offer some useful daily expressions. Watching them will help you enlarge your vocabulary and teach you correct language usage in different situations. Best of all, situation comedies are a fun way to learn.
    The Apprentice
    The American reality (现实) TV show is hosted by the famous businessman Donald Trump. It’s based on the idea of the final job interview for the final job. The show picks 16 people to compete for a job with Trump’s business. Those who fail their weekly tasks have to meet with Trump. They have to explain why they should not be fired (解雇).
    The Apprentice is useful for English students who want to learn how to make up a persuasive (令人信服的) argument. For example, rather than say “I think I did a good job”, one may also learn to throw off the possibility of uncertainty by saying, “I did a good job.”
    Desperate Housewives (DH)
    Desperate Housewives is set in an invented American town, Wisteria Lane. It follows a group of middle-aged women as they go through their daily family lives. But in fact, those women live a life of lies, secrets, criminal (犯罪的) acts, and mystery.
    This program is good at expressing the funny life of American neighbors. And, it’s the perfect comedy series for foreign learners wanting to see how to hold a relaxed daily conversation.
    Another reason for watching DH is to learn some expressions American families use that are not in your English language textbooks. For example, the mothers often use words such as “sport” and “you guys” to speak about their kids. 　　
    小题1:According to the passage, The Apprentice and DH are introduced because _____.
    A．they are now the most popular programs
    B．they are helpful in English learning
    C．they are advertised for English beginners
    D．they are enjoyed by most young people
    小题2:Through watching the two American comedy series, English learners can do the following EXCEPT _____.
    A．communicate with native speakers
    B．know about American culture
    C．pick up English daily expressions
    D．learn more English words
    小题3:In the author’s opinion, learning English through TV series is _____.
    A．commonB．difficultC．enjoyableD．possible
    小题4:We can learn from the passage that The Apprentice _____.
    A．tells a story of school life B．is about real life
    C．has 15 actorsD．is about some businessmen
    小题5:Which of the following statements about DH can we get from the introduction?
    A．The story happens in a village of America.
    B．The housewives join in the same job interview.
    C．The women in the American town lead a life full of sadness.
    D．It does well in describing an interesting neighborhood in America.

    Dan Bebber is a senior research fellow at the University of Exeter in Britain. He says research has shown that wild plants and animals are moving toward Earth's North and South poles as the planet warms.
    Mr Bebber wanted to know if the same thing was happening with organisms that attack agricultural crops. He examined reports of first sightings of new insects and diseases around the world. The records came from CABI - the Centre for Agricultural Bioscience International. He says the group began collecting information from developing and industrialized countries years ago.
    Dan Bebber and his research team studied 612 different organisms - from viruses and bacteria to insects like beetles and butterflies. They found that since 1960, crop pests and diseases have been moving toward the poles at an average rate of about 3 kilometers each year. Mr Bebber says this puts the most productive farmland in the world in danger.
    "As new species of pests and diseases evolve and potentially the environment for them becomes more amenable at higher latitudes, the pressure on the breadbaskets of the world is going to increase."
    Farmers face other threats. Invasive species passed through trade are also causing problems. Gene Kritsky is an Entomologist at the College of Mount St. Joseph in Ohio. He specialises in the study of insects. He says climate change may improve conditions for some invasive species.
    “It means that species in other parts of the world that might do well in warmer temperatures can now do well in the breadbasket of America.”
    Another Entomologist Christian Krupke of Purdue University says the effects of these changes will depend very much on the crop, the insect and the disease. But he says the research is a warning sign that people should care about climate change and do something about it.
    小题1:The purpose of Dan Bebber’s research was to find ______.
    A．if farmland could be moved to colder places thanks to global warming
    B．if diseases and insects harmful to crops were going towards colder areas
    C．if organisms were moving to the north and south poles
    D．if the number of crop pests was increasing
    小题2:According to Dan Bebber, if crop pests keep moving towards the poles, ______.
    A．it will be hard for farmers to kill them
    B．the most productive farmland will produce more crops
    C．the earth will not produce enough food to support the world
    D．the conditions for some crops may be improved
    小题3:Which of the following is not a threat that farmers have to face?
    A．Climate change helps crop pests to adapt to new environment.
    B．Foreign species are brought in by trade.
    C．Invasive species doing well in warmer places might do well in America.
    D．The impacts of the climate and species changes on crops are not easy to determine.
    小题4:The underlined word “amenable” in the fourth paragraph most probably means ______.
    A．agreeableB．terribleC．unfriendlyD．changeable

    For the people living in the Nile Basin, the river is their life．This 6,825 km waterway, whose watershed（流域）covers three million square kilometers, flows through mountains ,woodlands, lakes and deserts．Its potential for fishing, tourism and shipping is great—but so are its challenges. 
    Water shortage , already serious in Egypt and Sudan , will soon influence several other countries in the watershed as well．Today, about 160 million people depend on the Nile River for their living．Within the next 25 yeas ,the district's population is expected to double, adding to the demand brought about by growth in industry and agriculture．The frequent drought（干旱）adds to the urgency.
    Water quality is also a problem．Precious soil is washed out to sea．Wastes from industry and agriculture create pollution．Higher concentrations of salt influence irrigated soils．Water-borne diseases continue unchecked．In areas where it's hot and damp, water hyacinths choke off（阻止） lakes, dams and other sections of the river, making it difficult for fishing and other businesses to move forward.
    Native people along the narrow area of farmland have watched the sand move closer day by day．They’ve seen the river change course, and their only source（来源） of water thickened with mud．They’re very poor and have few choices.
    But a new program, the Nile Basin Initiative (NBI), is offering very practical assistance．The program is more than just a water-management project．It’s a plan for the social and economic development of a vast district: it concentrates on the needs of the poorest of the poor and the environment that supports them.
    These are whole ecosystem problems, calling for united solutions．Half the Nile Basin's countries are among the world's poorest nations；yet, somehow, they must find the resources, skills and political will to overcome these challenges.
    小题1:What are the great challenges the Nile Basin faces？    
    A．The development of shipping industry.
    B．Over fishing of native people.

    In the past ten years, many scientists have studied the differences between men and women. And they all got the same answer: The sexes(性别) are different, because their brains are different. And this, the scientists say, makes men and women see the world in different ways.
    Boys, for example, generally are better than girls at mathematical ideas. Boys also generally are better than girls at the kind of hand and eye movements necessary for ball sports. Girls, on the other hand generally start speaking earlier than boys. And they generally see better in the dark than boys and are better at learning foreign languages.
    What makes men and women better at one thing or another? The answer is the brain. The brain has two sides connected by nerve(神经) tracks. The left side generally is used for mathematics, speech and writing. The right side is used for artistic creation(创造) and the expression for emotions(情感). In men and women, different areas in each side of the brain develop differently. In boys, for example, it’s the area used for mathematics. In girls, it is the area used for language skills. Another interesting difference is that the two sides of a man’s brain are connected by a smaller number of nerves than the two sides of a woman’s brain are.
    小题1:Which of the following is the best title of the article?
    A．Research on the Brain
    B．Men and Women are Different in Brain
    C．People’s Different Brains
    D．Who Are Better, Boys or Girls
    小题2:__________ men and women think differently.
    A．The different brains make
    B．Sex makes
