    15．How I wish I________ my mouth before I shouted at my mum!（　　）
    A．shutB．have shutC．had shutD．would shut

    分析 我多么希望在对妈妈大吼前闭嘴．

    解答 答案是C．本题考查wish引导的宾语从句． wish引导的宾语从句往往用虚拟语气，与现在事实相反的愿望用过去时，be 动词用were；与过去事实相反的愿望用过去完成时；与将来事实相反的愿望用could/would+do；根据本题题干中的before I shouted 可知是与过去事实相反的愿望，所以答案是C．

    点评 在掌握虚拟语气的规则的基础上，判断题干属于什么类型的虚拟，然后根据语境，选用恰当的动词形式表达虚拟．

    14．A typical lion tamer （驯兽师） in people's mind is an entertainer holding a whip （鞭子）and a chair．The whip get all of the attention，but it's mostly for show．In reality，it's the chair that does the important work．When a lion tamer holds a chair in front of the lion's face，the lion tries to focus on all four legs of the chair at the same time．With its focus divided，the lion becomes confused and is unsure about what to do next．When faced with so many options，the lion chooses to freeze and wait instead of attacking the man holding the chair．
    How often do you find yourself in the same position as the lion？How often do you have something you want to achieve （eg．lose weight，start a business，travel more ）-only to end up confused by all of the options in front of you and never make progress？
    This upsets me to no end because while all the experts are busy debating about which option is best，the people who want to improve their lives are left confused by all of the conflicting information．The end result is that we feel like we can't focus or that we're focused on the wrong things，and so we take less action，make less progress，and stay the same when we could be improving．
    It doesn't have to be that way．Anytime you find the world waving a chair in your face，remember this：All you need to do is focus on one thing．You just need to get started．Starting before you feel ready is one of the habits of successful people．If you have somewhere you want to go，something you want to accomplish，someone you want to become …．take immediate action．If you're clear about where you want to go，the rest of the world will either help you get there or get out the way．
    29．Why does the lion tamer use a chair？A
    A．To trick the lion．
    B．To show off his skill．
    C．To get ready for a fight．
     D．To entertain the audience．
    30．In what sense are people similar to a lion facing a chair？A
    A．They feel puzzled over choices．
    B．They hold on to the wrong things．
    C．They find it hard to make changes．
    D．They have to do something for show．
    31．What is the author's attitude towards the experts mentioned in paragraph 3？B
    A．Tolerant      
    B．Doubtful       
    C．Respectful          
    D．Supportive
    32．When the world is"waving a chair in your face"，you're advised toC．
    A．wait for a better chance          
    B．break your old habits
    C．make a quick decision           
    D．ask for clear guidance．

    15．To be financially secure and spiritually pleased，a man who has an occupation ought to have two or three hobbies．It tends to make people laugh by saying："I will develop hobbies when I am retired．"Such a promise is like a bubble which will burst in the end，leaving pleasure forever beyond．On the other side，if a man is only interested in acquiring knowledge and abilities irrelevant to his daily work，it is also hard to get true pleasure in the long run．
    Broadly speaking，hobbies for those who have jobs should be practical．For example，it is impractical for a construction worker，after a hard week's manual labor，to develop the interest of playing football on Saturday afternoon．It is also unlikely for a politician or a business man，who has been working or worrying about serious things for six days，to attend drama courses at the weekend．
    It may also be said that laborers are divided into two classes：first，those whose work is work and whose pleasure is pleasure； and secondly，those whose work is everything and pleasure just exists in work．The former are the majority．They have their compensations．The long hours in the office or the factory bring them money，not only as the means of livelihood，but as a driving force for pleasure beyond their work．But for the second class，the working hours are never long enough．Each day is enjoyed like a holiday，and when real holidays come，they see them as interruptions．To both classes，the need of changing the angle of viewing work and pleasure is essential．Those who find it hard to enjoy their work are not fully enjoying the world they live in．However，it is more urgent for those whose work is their all pleasure to drive the work occasionally off their minds and develop hobbies．

    28．What can we learn from paragraph 1？C
    A．The best choice for a person is having three hobbies
    B．To relax one should broaden his knowledge in other fields
    C．Pleasure is acquired by enjoying work and hobbies
    D．Pleasure lies in how much one is involved in other fields
    29．Which hobby do you recommend to a software programmer？D
    A．Playing Chinese chess  
    C．Learning watercolor painting
    B．Writing poems         
    D．Joining in Mobike riding
    30．Which can substitute the underlined word in paragraph 3？B
    A．working hours    
    B．real holidays
    C．means of livelihood     
    D．drama courses
    31．What is the best title of the passageA
    A．Work and Pleasure      
    C．Holidays and Interruptions
    B．Hobbies and Relaxation 
    D．Manual Work and Brain Work．

    7．A German study suggests that people who were too optimistic about their future actually faced greater risk of disability or death within 10 years than those pessimists who expected their future to be worse．
    The paper，published this March in Psychology and Aging，examined health and welfare surveys from roughly 40，000 Germans between ages 18 and 96．The surveys were conducted every year from 1993 to 2003．
    Survey respondents were asked to estimate their present and future life satisfaction on a scale of 0 to 10，among other questions．
    The researchers found that young adults （age 18 to 39）routinely overestimated their future life satisfaction，while middle-aged adults （age 40 to 64）more accurately predicted how they would feel in the future．Adults of 65 and older，however，were far more likely to underestimate their future life satisfaction．Not only did they feel more satisfied than they thought they would，the older pessimists seemed to suffer a lower ratio of disability and death for the study period．
    "We observed that being too optimistic in predicting a better future than actually observed was associated with a greater risk of disability and a greater risk of death within the following decade，"wrote Frieder R．Lang，a professor at the University of Erlangen-Nuremberg．
    Lang and his colleagues believed that people who were pessimistic about their future may be more careful about their actions than people who expected a rosy future．
    "Seeing a dark future may encourage positive evaluations of the actual self and may contribute to taking im proved precautions （预防措施），"the authors wrote．
    Surprisingly，compared with those in poor health or who had low incomes，respondents who enjoyed good health or income were associated with expecting a greater decline．Also，the researchers said that higher income was related to a greater risk of disability．
    The authors of the study noted that there were limitations to their conclusions．Illness，medi cal treatment and personal loss could also have driven health outcomes．
    However，the researchers said a pattern was clear．"We found that from early to late adulthood，individuals adapt their expectations of future life satisfaction from optimistic，to accurate，to pessimistic，"the authors concluded．
    12．According to the study，who made the most accurate prediction of their future life satisfaction？B
     A．Optimistic adults．
    B．Middle-aged adults．
     C．Adults in poor health．
    D．Adults of lower income．
    13．Pessimism may be positive in some way because it causes peopleC．
    A．to fully enjoy their present life
    B．to estimate their contribution accurately
    C．to take measures against potential risks
    D．to value health more highly than wealth
    14．How do people of higher income see their future？A
    A．They will earn less money．
    B．They will become pessimistic．
    C．They will suffer mental illness．
    D．They will have less time to enjoy life．
    15．What is the clear conclusion of the study？D
    A．Pessimism guarantees chances of survival．
    B．Good financial condition leads to good health．
    C．Medical treatment determines health outcomes．
    D．Expectations of future life satisfaction decline with age．

    4．I've often wondered how exactly sleep，or lack of it，can have such an awful effect on our bodies and，guess what，how much we sleep switches good genes（基因） on and had genes off．
    In the first half of 2013，the Sleep Research Centre at the University of Surrey found a direct link between hours spent sleeping and genes．Every cell in our bodies carries genetic instructions in our DNA that act as a kind of operating handbook．However，each cell only"reads"the part of this handbook it needs at any given moment．
    Can sleep affect how a gene reads instructions？It's a question asked by Professor Derk-Jan Dijk at the University of Surrey．He set up an experiment and asked his volunteers to spend a week sleeping around seven and a half hours to eight hours a night and the next sleeping six and a half to seven hours．
    Blood samples were taken each week to compare which genes in blood cells were being used during the long and short nights．The results were rather surprising．Several hundred genes changed in the amount they were being used，including some that are linked to heart disease，cancer，and Type 2diabetes．Genes to do with cell repair and replacement were used much less．
    Sleep restriction（six and a half to seven hours a night） changed 380genes．Of these，220genes were down regulated （their power was increased）．Those affected included body-clock genes which are linked to diabetes（糖尿病）．One of the most downgraded genes is that which has a role in controlling insulin（胰岛素） and is linked to diabetes and insomnia（失眠）．The most upgraded gene is linked to heart disease．
    So changing sleep by tiny amounts can upgrade or downgrade genes that can influence our health and the diseases we suffer from when we sleep too little．
    The important message is that getting close to eight hours of sleep a night can make a dramatic difference to our health in just a few days through the way it looks after our genes．
    28．What kind of relation is directly discussed in the passage？A
    A．Sleeping hours and changes of genes．
    B．Sleeping hours and diseases．
    C．Changes of genes and diseases．
    D．Genes and health．
    29．What can we learn about Professor Derk-Jan Kijk's experiment？C
    A．The experiment was carried out to find the answer to how genes affect sleep．
    B．The experiment took a period of more than two weeks to reach a conclusion．
    C．His volunteers were divided into two groups with two different sleeping patterns．
    D．Blood samples of the volunteers were checked afterwards to decide how many genes changed in sleeping．
    30．Which of the following may be concluded from the passage？C
    A．The experiment was performed at the University of Surrey in early 2013．
    B．Body-clock genes are associated with heart disease，cancer and Type 2diabetes．
    C．Sleep restrictions may contribute to disease like diabetes，insomnia，and heart disease．
    D.7.5-8hours'sleep pattern makes little difference compared with 6.5-7hours'sleep pattern．
    31．Which of the following can be inferred from the findings of the sleep research？D
    A．When there is a sleep restriction，genes to do with cell repair and replacement function less．
    B．In a sleep，several hundred genes change in the amount．The more changes，the worse results．
    C．When genes are up regulated，they do good to health； when genes are down regulated，they do harm to health．
    D．Eight hours of sleep a day can be beneficial to our health in that it looks after our genes．
