    18．How will our continuously growing population affect our way of life，our environment，even our planet？No matter how you look at it，we will face （41）anextremely serious problem．By the middle of the 21st century，we （42）will have used（use） up all the oil that drives our cars if at the rate we're going．Even if scientists develop some new （43）ways（way）of feeding the human race，the crowded conditions on the earth will make （44）Itnecessary for us to look for open space somewhere else．But none of the planets in our solar system are able （45）to support（support） life at present．One possible solution （46）tothe problem，however，has recently been suggested by an American scientist，Professor Carl Sagan．His idea is （47）thatbefore the earth's resources are almost exhausted，it will be （48）totally（total）possible to change the atmosphere of Venus（金星）and so create a new world almost as large as earth itself．
    However，（49）beforehis idea is turned into reality，humans have a long way to go．On the one hand，Venus is much （50）hotter（hot）than the earth； on the other hand，there is only a tiny amount of water there．

    2．A new study has found that social media could be affecting the sleep of young adults．
    The study is a project of researchers at the University of Pittsburgh's School of Medicine．They found that young people who often use social media are more likely to suffer from sleep disorder than those who use social media less．The researchers say doctors should ask young adults about their use of social media when treating sleeping issues．
    "This is one of the first pieces of evidence that social media use really can influence your sleep，"said Jessica C．Levenson．She was the lead author of a report on the study．
    The researchers set out to examine the connection between social media use and sleep among young adults．Levenson noted that these young adults are possibly the first"generation to grow up with social media．"
    The researchers wanted to find out how often young people used social media sites like Facebook，Twitter，and Tumblr．For the study，they gave questionnaires to nearly 1，800adults，aged 19to 32．On average，members of the study group used social media sites one hour a day．They also"visited various social media 30times per week．"
    Thirty percent of the study's participants reported having serious problems with sleeping．Those people who used social media a lot were three times more likely to have a sleep disorder．And those who spent the most time on social media were twice as likely to suffer from sleep disturbances．
    Levenson said the number of times a person visits media is a better predictor of sleep problems than overall time spent on social media．If this is true，she adds，then practices that stop such behaviors may be most effective．

    32．What's the main idea of the text？C
    A．The search focuses on social media．
    B．The researchers manage to handle sleep problem．
    C．Social media affects sleep．
    D．Doctors treat young patients．
    33．When treating sleep problems，doctors are advised toB．
    A．offer some advice about giving up social media．
    B．ask the young patients about their use of social media．
    C．give young adults some medicine．
    D．ask about the patients'living conditions．
    34．How did the researchers mainly carry out the study？B
    A．By doing online research．
    B．By asking participants to fill in questionnaires．
    C．By collecting published data．
    D．By giving an example．
    35．What can be inferred from the text？D
    A．men are more likely to suffer from a sleep disorder than women．
    B．People often using social media are less likely to have a sleep disorder．
    C．Using computers less helps avoid sleep problems completely．
    D．Sleep problems can be determined by the times of a person visiting social media．

    18．It was New Year's night．An aged man raised his mournful eyes towards the deep blue sky，（41）wherethe stars were floating like white flowers on the surface of a clear calm lake．He had already passed sixty of the stages（42）eading（lead） to his certain goal-the tomb，and he had brought from his journey nothing but mistakes and regret．（43）Unfortunately（fortune），now his health was poor，his mind empty，his heart sorrowful，and his old age short of comforts．The days of his youth appeared like dreams before him，and he recalled the serious moment when his father placed him at the entrance of the two roads-（44）oneleading to a peaceful，sunny place，covered with beautiful flowers，fresh fruits；the other leading to a deep，dark cave，（45）whichwas endless，where poison flowed instead of water and where devils and poisonous snakes crawled．
