    14．一The rising frequency of smoggy days is making me deeply worried that one day we will have to rely on masks to survive．
    一           ！The government really should do something．（　　）
    A．Good ideaB．I got it
    C．You betD．That's all right

    分析 --越来越频繁的雾天让我担心有一天我们将不得不依靠口罩来生存．
    --的确．政府真的应该做点事情．

    解答 答案：C，考查交际语言的使用，根据空格后面"政府真的应该做点事情"可知表达的是赞同前面所说的，因此使用You bet"当然，的确"，Good idea"好主意"，I got it"我明白了"，That's all right"没关系，不客气"，故答案为C．

    点评 考查交际语言的使用，应联系前后句子的语境，对答案进行确定．

    4．第二节 根据短文内容，从短文后的选项中选出能填入空白处的最佳选项．选项中有两项为多余选项．
    Ways to Track Your Personal Health Information on Your Phone
    Your smart phone is a powerful and flexible tool for acquiring information related to your health．（36）FThere are other various ways that allow the user several approaches for acquiring health information．
    ◆（37）BThe sensors（传感器） built in to your phone can automatically capture selected types of health information when they are linked to suitable apps．Thus，the apps take advantage of the phone's stock hardware to deliver specialized health-related functions．（38）CNumerous apps use the phone's GPS to track outdoor activities like running or walking．A handful of apps also use the accelerometer（加速度计） to track indoor activities like treadmill running，which would be impossible to measure with the GPS．
    ◆Acquire information with a separate health sensor．The smart phone itself is a wonder of modern technology．（39）GHere are a few devices you can connect with your phone to track health information：Activity trackers like the fitbit，blood pressure monitor，heart rhythm monitor．Comprehensive platforms like Apple's Health app make it easy to tie all this information together．
    ◆Link to your electronic health records．Much of your health information may be stored in electronic health records maintained by your heath care providers．（40）EYou can access your health records through a patient portal（入口） on your phone or download it with the Blue Button function．

    A．See doctor with remote-controlled technology．
    B．Acquire information with the phone's sensors．
    C．A popular example is tracking physical activity．
    D．This is the most primitive way to track your health information．
    E．Patients are now allowed to access information stored in electronic health records．
    F．You can use your phone's native apps or a cloud storage service to track your health information．
    G．However，its greatest potential for health tracking may lie in the ability to connect to separate sensors．

    19．When you want to throw something out as"junk"，better take a second thought as it may be of great value．In fact，scientists made the same mistake with DNA years ago，and now they are trying to get it right．
          We often say that DNA is a kind of acid that contains our genes．But the truth is that genes only make up 1 to 2 percent of our DNA，which caused scientists to believe that the rest of it is useless．
         Nevertheless，instead of doing nothing，junk DNA，as it is called，turned out to be playing an important part in our body．If genes are like light bulbs，then junk DNA acts as switches．
          They control which genes are used in a cell and how active they are．For example，they can determine whether a cell becomes a lung cell or a neuron （神经元）．
           The study，published in the journal Nature on September 5，started in 2003，and 442 scientists from 30 labs around the world were involved，according to Reuters．It is considered the biggest breakthrough in genomics（基因学）in a decade because it might help scientists find the cause of certain diseases．
           It has long been known that many complicated diseases，such as cancer，are caused by tiny changes in DNA．But now scientists realize that most of the changes occur not in the genes themselves，but in the"junk"part of the DNA．They are able to keep track of how and why ihe switches change and then figure out new treatments and drugs．
    "Our former understanding of DNA was like getting a picture of Earth from space，"Eric Lander from the Broad Institute，US，told The New York Times．"You know the planet is there，but you cannot see exactly what it's like on the surface．"
         But now with the new study result"you can follow the roads and see the traffic circulation．That's exactly the same way we will use this data in cancer research，"explained Mark Rubin from Weill Cornell Medical College in New York．

    41．Which of the following would be the best title for the passage？C
    A．DNA--The Cause of Cancer
    B．What Is DNA？
    C．A New Discovery for"Junk DNA"
    D．A Misunderstanding of Genes
    42．What does the underlined phrase"get it right"in the first paragraph refer to？B
    A．Discovering new types of DNA．
    B．Recognizing the importance of junk DNA．
    C．Understanding the role genes play in DNA．
    D．Telling useful DNA from useless one．
    43．The author explains how different parts of DNA work by．B
    a．introducing a general theory
    b．making a metaphor（比喻）
    c．giving examples
    d．displaying research data
    A．ac
    B．bc
    C．ad
    D．cd
    44．The results of the study mentioned in the article show thatD
    A．cancer is caused by tiny changes in genes themselves
    B．the study of junk DNA is less important than the study of genes
    C．changes in junk DNA do not affect genes
    D．junk DNA is very important for the functioning of our cells
    45．Which of the following statements might Mark Rubin agree with？C
    A．The finding of our genes is enough to fight against cancer．
    B．The battle against cancer will be won within two years．
    C．The finding of junk DNA throws light on how we might cure cancer．
    D．The new treatments and drugs will change junk DNA quickly．

    3．I am a writer．I spend a great deal of my time thinking about the power of language-the way it can evoke （唤起）an emotion，a visual image，a complex idea，or a simple truth．Language is the tool of my trade．And I use them all-all the Englishes I grew up with．
         Born into a Chinese family that had recently arrived in California，I've been giving more thought to the kind of English my mother speaks．Like others，I have described it to people as"broken"English．But feel embarrassed to say that．It has always bothered me that I can think of no way to describe it other than"broken"，as if it were damaged and needed to be fixed，as if it lacked a certain wholeness．I've heard other terms used，"limited English，"for example．But they seem just as bad，as if everything is limited，including people's perceptions（认识）of the limited English speaker．
         I know this for a fact，because when I was growing up，my mother's"limited"English limited my perception of her．I was ashamed of her English．I believed that her English reflected the quality of what she had to say．That is，because she expressed them imperfectly her thoughts were imperfect．And I had plenty of evidence to support me：the fact that people in department stores，at banks，and at restaurants did not take her seriously，did not give her good service，pretended not to understand her，or even acted as if they did not hear her．
         I started writing fiction in 1985．And for reasons I won't get into today，I began to write stories using all the Englishes I grew up with：the English she used with me，which for lack of a better term might be described as"broken"，and what I imagine to be her translation of her Chinese，her internal （内在的） language．and for that I sought to preserve the essence，but neither an English nor a Chinese structure：I wanted to catch what language ability tests can never show；her intention，her feelings，the rhythms of her speech and the nature of her thoughts．

    41．By saying"Language is the tool of my trade"，the author means thatA．
    A．she is a writer by profession 
    B．she is fascinated by languages
    C．she works as a translator
    D．she uses English in foreign trade
    42．The author used to think of her mother's English asC．
    A．impolite
    B．amusing
    C．imperfect
    D．practical 
    43．Which of the following is TRUE according to Paragraph 3？B
    A．Americans do not understand broken English．
    B．The author's mother was not respected sometimes．
    C．The author'mother had positive influence on her．
    D．Broken English always reflects imperfect thoughts．
    44．The author gradually realizes her mother's English isD．
    A．well structured
    B．in the old style
    C．easy to translate
    D．rich in meaning 
    45．What is the passage mainly about？A
    A．The changes of the author's attitude to her mother's English．
    B．The limitation of the author's perception of her mother．
    C．The author's misunderstanding of"limited"English．
    D．The author's experiences of using broken English．

    18．As a Chinese saying goes，"Taste is actually a memory of childhood"．Local specialty food may not be popular among all people，but it offers outsiders a glimpse of local culture and history．
        Gongcheng"oil tea"is such a kind of food that would be considered"weird"by many first-time visitors to the remote county in the north of the Guangxi Zhuang Autonomous Region．Many people dislike its bitter and astringent（涩的） flavor when they take a sip．
    "It felt like drinking Chinese herbal medicine．I never expected that I would gradually accept it afterwards，and even become addicted to it，"said a traveler surnamed Zhang who comes from Shijiazhuang in northern China's Hebei province．
        Langshan village is said to be the birthplace of Gongcheng"oil tea"whose ideal ingredients are green tea and fermented tea．The village has preserved well its buildings and roads dating back to late Qing Dynasty （1644-1911），as well as its traditional way of making the special tea．
    Lin Fengyou，60，introduced the cooking process．She looks younger than her age，and attributes this to the benefits of drinking"oil tea"throughout the year．
        The first procedure is to use a wooden hammer to pound the tea while heating it in an iron pot，and then add edible oil and boiled water afterwards．She filters off the solid residues（余渣），and pours the glue-like green tea soup into bowls．Then，she adds salt，caraway seed，green onion，dried rice，fried groundnuts，sliced taro and fried beans．
        The taste of the"oil tea"is a mixture of the distinctive flavors of all its ingredients．Local people usually eat it together with glutinous rice（糯米） balls，rice dumplings and glutinous rice cake．
    The villagers consume"oil tea"three times a day．The tea soup is a healthy and refreshing food．"The tea soup to us is coffee to Westerners"，said Lin．"But it is tastier．"

    28．Many first-time visitors may find"oil tea"B when taking a sip．
    A．popular    B．strange     C．addicted       D．beneficial
    29．What can we learn about Lin Fengyou according to the passage？C
    A．She never expected that she would gradually accept"oil tea"．
    B．She is one of the reasons why the special tea has been preserved．
    C．She thinks drinking"oil tea"throughout the year makes her look younger．
    D．She drinks"oil tea"three times every day and considers coffee tastier．
    30．Which is the correct order of cooking"oil tea"according to Lin Fengyou？A
    a．pour the glue-like green tea soup into bowls
    b．heat the tea in an iron pot and pound the tea
    c．add salt，caraway seed，green onion，dried rice，etc
    d．add edible oil and boiled water
    e．filter off the solid residues
    A．bdeac      B．dbace       C．acebd   D．beadc
    31．Which column is this passage probably taken from？D
    A．Culture & EducationB．Entertainment  C．HealthD．Travel．
