    Thousands of puffins(海鹦) live in Maine and on islands in the Gulf of Maine. But the puffins may be in danger. Last summer, the percentage of laid eggs that successfully produced baby puffins took a dive. Scientists also found a decline in the average body weight of the adult and baby puffins on Machias Seal Island, home to the area’s largest colony. Over the winter, dozens of the seabirds from the region were found dead, likely from starvation.
    What’s causing the puffin trouble? Scientists think it may be a shortage of food. With ocean temperatures rising, fish populations have moved around. Normally, puffins’ primary food source is herring, a type of fish. A lack of herring in the area could be causing the problem.
    Butterfish from the south have become more abundant in the Gulf of Maine and could be a new food source for birds. But Steve Kress says butterfish may be too big and round for baby puffins to swallow.
    Puffins spend most of their lives at sea. They come ashore to breed each spring and return to the ocean in August. The chicks swim to sea about 40 days after hatching. Puffin populations stretch across the North Atlantic, from Maine to northern Russia.
    Maine’s puffin population has been at risk in the past. In the 1800s, they were hunted for their food, eggs and feathers. By 1901, only one pair of puffins remained in the state. Thanks to the help of local lighthouse keepers and seabird restoration programs, the state’s puffin population has been restored to more than 2,000 birds.
    Scientists aren’t sure what will happen to the Gulf of Maine’s puffins. The birds may move further north. Kress says he hopes the Gulf population will sustain itself and then he continued. “You never know what climate change will bring,” Kress said. “Historically fish could move out and more southerly fish could move in, and puffins may adapt to the new fish. Only they will know how the story will unfold.”

    PERTH—Search crews will send a submarine(潜航器)deep into the Indian Ocean on Monday for the first time to try to determine whether signals detected by sound-locating equipment are from the  missing Malaysian plane's black boxes, the Australian head of the search said.
    Angus Houst on said the crew on board the Ocean Shield  will send the underwater vehicle sometime Monday evening. The Bluefin 21 submarine can create a sonar(声呐)map of the area to chartany wreckage(残骸)on the seafloor.
    The move comes after crews picked up a series of underwater sounds over the past two weeks that were consistent with an aircraft's black boxes.
    “We haven’t had a single detection in six days, and l guess it’s time to go under water,” said Houston.
    “Analysis of the four signals has reduced the search area on the ocean floor. The experts have therefore determined that the Australian Defense Vessel Ocean Shield will stop searching with the Towed Pinger Locator(拖曳声波定位仪)later today and use the underwater vehicle Bluefin 21 as soon as possible," he said at a news conference in Perth.
    But Houston warned the switch to the submarine will not automatically "result in the detection of the aircraft wreckage. It may not.”
    He said the submarine will take 24 hours to do each task, including two hours to dive, 16 hours to search the bottom, then two more hours hack up and four hours to download data.
    Recovering the plane's flight data and cockpit(飞行员座舱)voice recorders is necessary For investigators to try to figure out what happened to Flight 370, which disappeared on March 8. 
    Houston said the search using the submarine will be a slaw and painstaking process.
    The submarine takes six times longer to cover the same area as the pinger locator,and will need about six weeks to two months to examine the present underwater zone. The signals are also coming from 4,500 meters (15,000 feet) below the surface, which is the deepest the submarine can dive.
    小题1:The submarine will be sent deep into the Indian Ocean on Monday to _____ .
    A．create a sonar trap of the area
    B．pick up underwater sounds
    C．see if the signals detected are from the target black boxes
    D．reduce the search area on the ocean floor
    小题2:According to the passage, the submarine_______ .
    A．will download data of the black boxes
    B．can find the aircraft wreckage within 24 hours
    C．will recover the plane's flight data and voice recorder
    D．can dive to a depth of no more than 4,500 meters
    小题3:The underlined sentences in the passage indicate that______.
    A．the switch of the submarine may not function properly
    B．the Ocean Shield will switch to submarine when it is necessary
    C．the submarine will detect the wreckage of the plane automatically
    D．the detection of the wreckage can't be guaranteed by using the submarine
    小题4:The search will be a slow and painstaking process, mainly because _____ .
    A．the underwater sounds were consistent with an aircraft's black boxes
    B．the submarine travels slowly and the ocean is deep
    C．they haven't had a single detection in six days
    D．Ocean Shield stops searching wine the towed pinger locator

    LONDON, Feb. 18，2014 （Xinhua News agency） —Britain will send experts to East China's Shanghai to learn from the city's experience in maths teaching in an attempt to raise the teaching standards.
    British Education Minister Elizabeth Truss is to lead a delegation of experts on a fact-finding mission to Shanghai's schools next week to see how children there have become the best in the world at maths, to get a first-hand look at maths classes and teaching methods there, and particularly to investigate why the performance of almost all children in Shanghai is high, regardless of gender or income.
    Britain was last year placed 50th out of 148 countries and regions in the World Economic Forum's competitiveness ranking in quality of maths and science education. Two years ago, Shanghai topped the 2012 international PISA tables for maths, while England was ranked in 26th place. The top five were all in Southeast Asia, with 15-year-olds in Shanghai judged to be three years ahead of their peers in maths.
    The education department said: "England's performance in maths has lagged behind while other countries have improved and overtaken us, including Poland and Germany." Actually, it is the latest step in the government's drive to raise standards in maths, looking at what has made schools in the far East the most successful in the world in teaching the subject.
    "Shanghai is the top-performing part of the world for maths—their children are streets ahead. Shanghai and Singapore have teaching practices and a positive mind that make the difference. They have a belief that diligence makes up for lack of ability," Truss said. "Our new curriculum has borrowed from theirs because we know it works—early learning of key arithmetic, and a focus on times tables and long division（长除法）, for instance."
    She was determined to change the situation as performance in maths is weakening the country's skills base and threatening the productivity and growth. The government is emphasizing maths because of the importance of good grades in the subject to young people competing for good jobs in a global labor market and to the economy more generally.
    An education and skills survey released by the Confederation of British Industry last year showed that 30 percent of employers reported dissatisfaction with the standard of school and college leavers' numeracy. More than two-thirds of employers said they wanted both maths and science promoted more in schools.
    小题1:Why does the British government send a delegation of experts to Shanghai?
    A．To see how children from rich families have become the best at maths.
    B．To investigate why the performance of almost all children in China is high.
    C．To get a first-hand look at science classes and teaching methods there.
    D．To raise the teaching standards in maths in Britain.
    小题2:Which of the following statements is true according to the two international competition results?
    A．British students performed better in 2013 than in 2012.
    B．British students did better than the students from Poland in 2013.
    C．The students from Singapore did better than the students from Germany.
    D．The students from Germany did better than the students from Poland.
    小题3:What has made schools in Shanghai the most successful in teaching maths in the eye of Truss?
    A．Curriculum and teaching methods.
    B．Teaching practices and a positive mind.
    C．Early learning of key arithmetic and times tables.
    D．A focus on times tables and long division.
    小题4:How will students’ poor performance in maths affect the country eventually?
    A．By threatening the country's competitiveness of economy.
    B．By weakening the country's political system.
    C．By losing international competitions in education.
    D．By failing to find jobs in a global labor market.
    小题5:What can we infer from the news?
    A．The students in Britain don’t work hard at Maths.
    B．The students in shanghai are the smartest in the world.
    C．The education of science in Britain is no better than that of maths.
    D．Most British citizens are dissatisfied with teachers’ work.

    The increase in tuition fees has led to a “clear drop” in the number of English students applying for university places this autumn. There are 15,000 “missing” applicants（申请人） this academic year, according to the Independent Commission on Fees. Chairman Will Hutton said: “We’re asking our young men and women to have more debt than any other country in the world — it’s higher than the average debt in the US. It’s not clear whether those lost students this year will return next year, or if it’s a storm warming of a worrying trend.”
    But the commission’s report says there does not seem to be an impact on poorer communities. The commission found there was no significant change in the application rate to the key universities, such as Oxford or Cambridge. The decline（下降） in England has not been mirrored（再现） in other parts of the UK where fees have not been raised, and the drop can only partly be explained by falling numbers of young people in the population. Students from Scotland attending Scottish universities do not pay fees, while the Welsh Assembly says it will pay fees above ￡3,465 for Welsh students attending UK institutions.
    The average tuition fee at English universities this year is ￡ 8,385, rising to ￡ 8,507 next year. UK and EU students have access to government-backed loans to pay the fees. And the survey of 1,000 pupils aged 15-18, carried out this April, found that the majority expected to go on to higher education as people continue to understand that university remains a good long term investment（投资） in their future.
    A spokeswoman at the Department for Business, Innovation and Skills which is responsible for universities, said: “Students shouldn’t be forced to put off going to university for financial reasons. Most students will not have to pay in advance, and no one will have to start paying back their student loan until they start to earn at least ￡ 2l,000 per year.”
    小题1:From the first paragraph, we know that        .
    A．the rising tuition fees have a great effect on English students
    B．many English students are missing the final examinations
    C．the lost English students will find their way back
    D．it’s a trend that English students are dropping out of school
    小题2: Why is there still a drop of applicants though fees have not been raised?
    A．Because the students live in poor communities.
    B．Because education is free for Scottish students.
    C．Because there are less young students in the area.
    D．Because Welsh students will pay fees above￡3,465.
    小题3:What’s the students’ attitude to universities in the survey?
    A．They will stop applying for university places this autumn.
    B．They feel universities takes up too much time.
    C．They are anxious to go to a key university.
    D．Most of them are willing to go to university.
    小题4:The spokeswoman in the last paragraph advises students to        .
    A．put off going to university
    B．pay for the fees in advance
    C．reduce the anxiety about the rising fees
    D．pay back their loan soon aller graduation

    LONDON (Reuters)    Ecotourism is causing a lot of damage to wildlife and may be endangering the survival of the very animals people are flocking to see, according to re­searchers.
    Biologists and conservationists are worried because polar bears, dolphins, penguins and other creatures are getting stressed and losing weight and some are dying.
    "Evidence is growing that many animals do not react well to tourists in their backyard，” New Scientist magazine said.
    The immediate effects "researchers have noticed are changes in behavior, heart rates. or stress hormone levels but they fear it could get much worse and over the long term “ could endanger the survival of the very wildlife they want to see. ”
    Although money produced through ecotourism, which has been growing at about 10-30 percent a year, has major benefits for poor countries and people living in rural areas, the Swiss-based World Conservation Union (IUCN) and some governments fear not all projects are audited（审计） and based on environmentally friendly policies，according to the magazine.
    Transmission of disease to wildlife，or small changes to wildlife health through dis­turbance of daily life or increased stress levels, while not obvious to the casual observer, may translate to lower survival and breeding，” said Philip Seddon , of the University of Otago in Dunedin, New Zealand.
    Scientists have noticed that bottleneck dolphins along the northeastern coast of New Zealand become nervously excited when tourist boats arrive. Similar changes in behavior have been observed in polar bears and yellow-eyed penguins in areas visited by colorists are producing smaller babies.
    Conservationists are now calling for more research into the effect of ecotourism on ani­mals and say the industry must be developed carefully. They also want studies done before new ecotourism projects are started.
    “The animals’ welfare should be very important because without them there will be no ecotourism，” said Rochelle Constantine of the University of Auckland in New Zealand
    小题1:Which is not discovered to have changed in animals disturbed by tourists?
    A．behaviorB．birth rateC．hormone levelsD．heart rates
    小题2:We may learn from the text that _____.
    A．ecotourism must be developed properly
    B．polar bears are losing weight without enough food
    C．all the poor countries have stopped ecotourism
    D．money produced through ecotourism should be spent on wildlife
    小题3:Which of the following is NOT mentioned in the text?
    A．Many animals do not react well in their backyard
    B．Studies should be done before new ecotourism projects are started
    C．Ecotourism has been growing at about 10—30 percent a year.
    D．polar bears in areas visited by ecotourists are producing smaller babies.
    小题4:What Rochelle Constantine said in the last paragraph implies that _____.
    A．if people want to get high income, they must develop ecotourism
    B．animals have rights to live their own life
    C．animals are people's good friends
    D．people should take good care of wildlife
