    An alcohol breath test (ABT) is often used by the police to find out whether a person is drunk while driving. In the United States, the legal blood alcohol limit is 0.08% for people aged 21 years or older, while people under 21 are not allowed to drive a car with any level of alcohol in their body. A “positive” test result, a result over the legal limit, allows the police to arrest the driver. However, many people who tested positive on the test have claimed that they only drank a “non-alcoholic” energy drink. Can one of these energy drinks really cause someone to test positive on an ABT? Researchers in Missouri set up an experiment to find out.
    First, the amount of alcohol in 27 different popular energy drinks was measured. All but one had an alcohol level greater than 0.005%. In nine of the 27 drinks, the alcohol level was at least 0.096%.The scientists then investigated the possibility that these small levels of alcohol could be discovered by an ABT. They asked test subjects to drink a full can or bottle of an energy drink and then gave each subject an ABT one minute and 15 minutes after the drink was finished.
    For 11 of the 27energy drinks, the ABT did find the presence of alcohol if the test was given within one minute after the drink was taken. However, alcohol could not be discovered for any of the drinks if the test was given 15 minutes after the drink was consumed. This shows that when the test is taken plays an important role in the test result. The sooner the test is conducted after the consumption of these drinks, the more likely a positive alcohol reading will be obtained.

    Cultural Center Adds Classes for Young Adults
    The Allendale Cultural Center has expanded its arts program to include classes for young adults. Director Leah Martin announced Monday that beginning in September, three new classes will be offered to the Allendale community. The course titles will be Yoga for Teenagers; Hip Hop Dance: Learning the Latest Moves; and Creative Journaling for Teens: Discovering the Writer Within. The latter course will not be held at the Allendale Cultural Center but instead will meet at the Allendale Public Library.
    Staff member Tricia Cousins will teach the yoga and hip hop classes. Ms. Cousins is an accomplished choreographer (舞蹈教师) as well as an experienced dance educator. She has an MA in dance education from Teachers College, Columbia University, where she wrote a thesis on the pedagogical (教学法的) effectiveness of dance education. The journaling class will be taught by Betsy Milford. Ms. Milford is the head librarian at the Allendale Public Library as well as a columnist for the professional journal Library Focus.
    The courses are part of the Allendale Cultural Center’s Project Teen, which was initiated by Leah Martin, Director of the Cultural Center. According to Martin, this project is a direct result of her efforts to make the center a more essential part of the Allendale community. Over the last several years, the number of people who have visited the cultural center for classes or events has steadily declined. Project Teen is primarily funded by a generous grant from The McGee Arts Foundation, an organization devoted to bringing arts programs to young adults. Martin oversees the Project Teen board, which consists of five board members. Two board members are students at Allendale’s Brookdale High School; the other three are adults with backgrounds in education and the arts.
    The creative journaling class will be cosponsored by Brookdale High School, and students who complete the class will be given the opportunity to publish one of their journal entries in Pulse, Brookdale’s student literary magazine. Students who complete the hip hop class will be eligible to participate in the Allendale Review, an annual concert sponsored by the cultural center that features local actors, musicians, and dancers. All classes are scheduled to begin immediately following school dismissal, and transportation will be available from Brookdale High School to the Allendale Cultural Center and the Allendale Public Library. For more information about Project Teen, contact the cultural center’s programming office at 988-0099 or drop by the office after June 1 to pick up a fall course catalog. The office is located on the third floor of the Allendale Town Hall.

    小题2:According to Leah Martin, what was the direct cause of Project Teen?
    A．Tricia Cousins was available to teach courses in the fall.
    B．Community organizations were ignoring local teenagers.
    C．The McGee Arts Foundation wanted to be more involved in Allendale’s arts programming.
    D．She wanted to make the cultural center a more important part of the Allendale community.
    小题3:Which of the following factors is implied as another reason for Project Teen?
    A．The number of people visiting the cultural center has declined over the last several years.
    B．The cultural center wanted a grant from The McGee Arts Foundation.
    C．The young people of Allendale have complained about the cultural center’s offerings.
    D．Leah Martin thinks classes for teenagers are more important than classes for adults.

    The koala is one of Australia’s most treasured creatures, which is a lovely little creature. But now, it is in big trouble.
    Affected by habitat (栖居地) loss and climate change, like many other uniquely Australian animals, koalas are being squeezed into smaller regions. But at present, it is a deadly disease, a somewhat silent killer that causes a further decline in the koala population,  that is worrying many scientists about the fate of the koala.
    The killer is Chlamydia, which has caused symptoms in up to 50 percent of the wild koalas, with probably even more infected (感染) but not showing symptoms. It has been particularly severe in Queensland, where nearly all koalas are infected. The disease causes many symptoms including eye infections, which can lead to blindness, making it difficult for them to find their primary food.
    Treating Chlamydia in wild koalas is a challenge. There is no treatment available for it. Only a small percentage of the animals can be treated successfully and returned to the wild. Besides, there is no national plan in Australia to save the koala；it is up to each region to make management plans for its koala population.
    The good news is that researchers are working to test a vaccine (疫苗) that would help prevent further spread. If all goes well, plans can be carried out to distribute the vaccil1e more widely. But it’s impossible to vaccinate all wild koalas.
    Another possibility would be to make vaccine distribution a routi11e part of treatment for the thousands of koalas brought into care centers every year after they are injured by cars or dogs.
    While it is a combination of problems that are affecting the wild koala population, many experts believe this vaccine would be an important step in helping koalas survive longer. It may buy enough time to give researchers a chance to solve some of the other problems facing Australia’s koalas.
    小题1:Which isn’t considered the main cause of koala’s population decline?
    A．Habitat loss.B．Injuries from cars and dogs.
    C．Climate change.D．A deadly disease.
    小题2:The third paragraph mainly tells us     .
    A．the serious result Chlamydia has caused to the koala
    B．Chlamydia affected the koala only in particular regions
    C．the most serious symptom of Chlamydia is eye infections
    D．Chla1nydia can seriously affect koala’s primary food
    小题3:The underlined word “it” in the fourth paragraph probably refers to     .
    A．the koalaB．ChlamydiaC．national planD．eye infection
    小题4: We can learn from the text that the vaccine     .
    A．would cure the killer Chlamydia quite effectively
    B．would only be distributed in koala care centers
    C．has already been put into practical use in Australia
    D．cannot be distributed to all the infected koalas
    小题5:It can be inferred from the text that     .
    A．a national plan for saving koalas will be made soon in Australia
    B．koala population is declining only in a few regions
    C．researchers need enough time to so1ve the koala problems
    D．experts have lost the best chance to save the infected koalas

    March 22, 20II---Most restaurants in the United States offer their customers a glass of tap water at no charge with their meal, but this week many restaurants are asking dinners to pay a dollar, or more, for a glass of water. Cards on their tables explain that this small amount helps bring clean water to children around the world. It’s called the UNICEF Tap Project.
    “UNICEF’s Tap Project is really all about bringing attention to the fact that over 900 million people around the globe do not have access to good, clean, healthy drinking water,” says Cary Stem, who heads the US Fund for UNICEF. She adds that water-borne illness is the second-highest cause of preventable childhood death in the world.
    “Each and every day approximately 4,100 children die just because they don’t have that access - 4,100 every single day.”
    The public service campaign encourages people to help change that statistic with a simple, affordable action: paying a dollar to get a glass of tap water at a restaurant.
    “One dollar buys enough good, clean water for a child for 40 days,” Stem says.
    “The tap project has expanded since it began five years ago with 300 restaurants in New York City. This year, Stem says, about 3,000 restaurants across the country are participating in the campaign. We raised about $2.5 million over the last five years of this campaign,” says Stem. “Last year, we raised over $1 million for the first time. This year we’re hoping to top that.”
    Stem credits the continued success of the campaign to an army of volunteers who support the tap project and raise money in their communities.
    The UNICEF Tap Project is promoting its efforts with a simple motto: when you take water, give water. Currently, UNICEF works in more than 100 countries around the world to improve access to safe water and sanitation facilities in schools and communities.
    Stem hopes that, by participating in the project, more Americans will realize that what they often take for granted is a precious and scarce resource in many other parts of the world.
    小题1:Restaurants began to charge for tap water to _______.
    A．increase their profit
    B．urge customers to save water
    C．raise people’s awareness of the world water problem
    D．collect money for those without access to safe water
    小题2:We can learn from the text that the Tap Project ________.
    A．began in New York City
    B．was started by volunteers
    C．is hoping to collect $2.5 million this year
    D．provides help for 1,000 countries in the world
    小题3:It can be learned that _______.
    A．the Tap Project began in 2006
    B．America suffers a serious problem
    C．4,100 children die of water pollution every year
    D．water-borne illnesses are the biggest killer of children
    小题4:How does Cary Stem feel about the work of the Tap Project?
    A．ConcernedB．HopefulC．DisappointedD．Angry

    A public high school in the rural town of Boonsboro，Maryland，offers a special program recently. Top students in the ninth and tenth grades can attend single－sex classes for math，science，English and social studies.
    The aim is to help teenagers keep their mind on their work by keeping males and females apart. Rebecca Brown chooses the students for what Boonsboro High School calls the Academy. “What we really want to do is take that top group of kids and take them to the very highest level they can achieve here，so that they’re prepared for college，” she said. They need high marks and test scores and strong teacher recommendations. They also need to be involved in activities.
    Michael Bair has been at Boonsboro High School for twenty years and directs the Academy. His ninth－grade English class for boys centers on books that he believes boys find interesting. “The novels they’re reading now，are very manly novels. They’re novels that deal with the arrogance(傲慢)of man and the pride of man.” One of those books，for example，is “The Call of the Wild” by Jack London. This classic story tells of a dog stolen from his home and sold to work as a sled dog in Canada’s Klondike Gold Rush.
    On this day，the students are working in small groups. Vincent and Logan explain why they’re drawing pictures that relate to the story. Vincent said，“The main character，Buck，gets abducted(绑架),? and they send him off to the Yukon in a train. So I’m drawing part of the story where he’s in the train. It gets you to visualize the setting of the story and gets you to think more about what’s going on in the story，the important events of the story.”“ Instead of just doing work sheets about it，this is a lot more fun，” Logan added happily.
    Morgan Van Fleet likes being in the Academy. She says boys and girls act differently when they are together in a classroom. “To me，it almost seems like it’s hindering(妨碍)? your chances at developing yourself because you’re more focused on ‘Oh，I wish they’d shut up. Oh，what do they think of me？’ instead of focusing on what’s the homework or what’s going on in this class，what’s the lesson.”
    小题1:What is the purpose of the text?
    A．To educate.B．To persuade.C．To instruct.D．To introduce.
    小题2:In Rebecca Brown’s opinion，________.
    A．any student in Boonsboro High School can take part in the program
    B．students in the program are expected to get well prepared for college
    C．students can all achieve their highest levels in the program
    D．students don’t have to join in the activities.
    小题3:The underlined word “visualize” in Paragraph 4 probably means “________”．
    A．form a picture ofB．pay a visit to
    C．take a look atD．have a gift for
    小题4:What can we conclude from the text?____________.
    A．Michael Bair considers it unsuitable for boys to read the book “The Call of the Wild”．
    B．Vincent thinks that his drawings can help understand the novel better.
    C．Jack London is a main character in the book “The Call of the Wild”．
    D．Morgan Van Fleet thinks the program does no good to her.
    小题5:The text is probably taken from________.
    A．a school’s introductionB．a teacher’s diary

    A deadly strain of avian flu may have passed between people for the first time, experts believe.The avian influenza A (H7N9) virus is thought to have been transmitted between father and daughter in eastern China, according to research published online by the British Medical Journal (BMJ).
    The findings provide the strongest evidence yet of H7N9 transmission between humans since its discover in February, but its ability to transmit itself was deemed "limited and non-sustainable" by the Chinese researchers behind the study.At the end of June 133 cases had been reported, including 43 deaths. Most infections have been among people visiting markets, selling live birds or among those who had contact with live poultry（家禽） in the seven to 10 days before becoming ill.
    The latest study examined the case of a 60-year-old father who regularly visited a live poultry market and became ill five to six days after his last visit in March. He was admitted to hospital with fever, cough and shortness of breath. Despite intensive care treatment he died of multiple organ failure on 4 May. His 32-year-old daughter, who was previously healthy, looked after him at his bedside before he was admitted to intensive care. She had no known exposure to live poultry before falling ill with a very high temperature, cough and fever. The daughter developed symptoms six days after her last contact with her father and was admitted to hospital where she died of multiple organ failure on 24 April.
    Follow-up investigations(调查) uncovered almost genetically identical virus strains from each patient, suggesting transmission from father to daughter. Another 43 people were also tested who had had close contact with the father, daughter or both.
    Dr Peter Horby, senior clinical research fellow at the Oxford University Clinical Research Unit in Hanoi, Vietnam, said of the study: "The most likely source of infection for the daughter was her father, during the period that she cared for him while he was ill. "He said “limited person to person transmission had been reported for other strains like H5N1 , H7N7, and the pig origin flu virus H3N2. Those strains had been around for more than a decade but have not progressed any further down the path towards a world-wide virus.” “Limited human-to-human transmission of H7N9 virus is therefore not surprising, but strengthening to monitor it was still needed,” Dr Horby added.
    小题1:What’s the main idea of the passage ?
    A．The findings about H7N9 transmission only between father and daughter .
    B．H7N9 transmission may be spreading between people .
    C．133 cases of H7N9 transmission have been reported .
    D．Both the father and daughter died of multiple organ failure.
    小题2:The reason why the daughter died of multiple organ failure was that _____.

    B．she was exposed to live poultry before falling ill.
    C．she had close contact with the father while caring for her sick father .
    D．she sold live birds in five to six days before falling ill .
    小题3:Which of the following is Wrong about H7N9 transmission?
    A．It was limited and non-sustainable
    B．It was person to person transmission
    C．It wasn’t progressed any further down the path towards a world-wide virus.
    D．It happened between father and daughter .

    That Upper class people generally have more educational opportunities, greater financial security, and better jobs than people from lower social classes, but that doesn’t mean they’re more skilled at everything. A new study finds, surprisingly, that lower class people are better at reading the emotions of others.
    The researchers were inspired by observing that, for lower class people, success depends more on how much they can rely on other individuals. For example, if you can’t afford to  buy support services, you have to rely on your neighbors or relatives to watch the kids while you’re busy.
    One experiment researched on volunteers who worked at a university: some had graduated from college and others had not. Researchers used the educational level as an indicator（标志）for social classes. The volunteers did a test of emotion perception（感知）, in which they were instructed to look at pictures of faces and indicate which emotions each face was displaying. People with more education performed worse on the task than people with less education.
    In another study, university students who were of higher social status had a more difficult time accurately（准确）reading the emotions of a stranger.
    These results suggest that people of upper-class status aren’t very good at recognizing the emotions other people are feeling. This is because they remember their upper status and they think they can solve their problems without relying on others.
    In the third experiment, people were made to feel that they were at a lower social class than they actually were, and they got better at reading emotions.
    “The differences between upper-class people and lower-class people are not something ingrained（根深蒂固的）,” Kraus says. “It’s the cultural environment leading to them.” This work helps show that the traditional image of the classes is wrong. “It’s not true that a lower-class person, no matter what kind of person, is going to be less intelligent than an upper-class person. It’s all about the social environment the person lives in, and the specific challenges the person faces. If you can change the environment even temporarily, social class differences in lots of behaviors can be removed.”
    小题1:According to the passage, when lower-class people meet problems, they tend to ______.
    A．turn to othersB．work even harder
    C．feel more frustratedD．learn from upper-class people
    小题2:Why did people perform better in emotion perception in the third experiment?
    A．Because they became less independent.
    B．Because they didn’t know they were cheated.
    C．Because they felt they must ask for help from other.
    D．Because they were made to understand lower-class people.
    小题3:What does the passage mainly talk about?
    A．Upper-class people are not skilled at everything.
    B．Upper-class people have trouble recognizing others’ emotion.
    C．Lower-class people need to be given more employment opportunities.
    D．There are many differences between upper-class people and lower-class people.
