    15．By 2050，a completely new type of human evolve as a result of extremely new technology，behavior，and natural selection．This is according to Cadell Last，a researcher at the Global Brain Institute，who claims mankind is undergoing a major"evolutionary transition"．
    In less than four decades，Mr．Last claims we will live longer，have children in old age and rely on artificial intelligence to do ordinary and boring tasks．This shift is so significant，he claims，it is comparable to the change from monkeys to apes，and apes to humans．"Your 80or 100is going to be so radically different than your grandparents，"Mr．Last says，who believes we will spend much of our time living in virtual reality．Some evolutionary scientists believe this age could be as high as 120by 2050．
    Mr．Last claims humans will also demonstrate delayed sexual maturation，according to a report by Christina Sterbenz in Business Insider．This refers to something known as life history theory which attempts to explain how natural selection shapes key events in a creature's life，such as reproduction．It suggests that as brain sizes increase，organisms need more energy and time to reach their full potential，and so reproduce less．
    Instead of living fast and dying younger，Mr．Last believes humans will live slow and die old．"Global society at the moment is a complete mess，"he told MailOnline．"But in crisis there is opportunity，and in apocalypse （启示） there can be transformation．So I think the next system humanity creates will be far more sophisticated，fair，and abundant than our current civilization．"
    "I think our next system will be as different from the modern world，as our contemporary world is from the medieval （中世纪的） world．The biological clock isn't going to be around forever，"he added，and said that people could pause it for some time using future technology．
    The change is already happening．Today，the average age at which a woman in Britain has her first baby has been rising steadily stands at 29.8．In the US，just one percent of first children were born to women over the age of 35in 1970．By 2012，that figure rose to 15percent．
    "As countries become socio-economically advanced，more and more people，especially women have the option to engage in cultural reproduction，"Mr．Last added．And as well as having more child-free years to enjoy leisure time，he believes artificial intelligence will make up the need for low-skill jobs．We may also spend a large amount of time living in virtual reality．"I'm not quite sure most people have really absorbed the implications of this possibility，"Mr．Last said．
    His views are detailed in a paper，titled"Human Evolution，Life History Theory，and the End of Biological Reproduction"published Current Aging Science．

    59．According to Cadell Last，a completely new type of human will appear because ofA．
    ①artificial intelligence ②new technology ③natural selection ④mundane tasks
    ⑤behavior
    A．②③⑤
    B．①②③
    C．③④⑤
    D．①②⑤
    60．Which statement is compared by Mr．Last to the change from monkeys to apes，and apes to humans？D
    A．We have diseases and die young．
    B．We give birth to a child when we are young．
    C．We spend less time in virtual reality．
    D．We use intelligent robots to do everyday housework．
    61．The underlined words in the third paragraph most probably mean"A"．
    A．Organisms need more energy and time to ripen．
    B．Natural selection shapes key events．
    C．Reproduction．
    D．Reproduce less．
    62．In the next system Mr．Last explained we can infer thatA．
    A．women are engaged in careers or hobbies instead of giving birth to babies
    B．women are engaged in playing computer games rather than working
    C．women are engaged in cultural reproduction in place of men
    D．women are engaged in living in virtual reality without options．

    10．Cellphone feels like a part of your body？Calling mobile phones the"remote control"for life，market research firm Synovate's poll（民意调查） said cell phones are so ubiquitous that by last year more humans owned one than did not．Three-quarters of the more than 8，000 respondents（受访者） polled online in 11 countries and regions said they take their phone（s） with them everywhere，with Russians and Singaporeans the most attached．More than a third also said they couldn't live without their phone（s），topped by Taiwanese and again Singaporeans，while one in four would find it harder to replace the mobile than their purse．Some two-thirds of respondents go to bed with their phones nearby and can't switch them off，even though they want to，because they're afraid they'll miss something．
    "Mobiles give us safety，security and instant access to information．They are the number one tool of communication for us，"Jenny Chang，Synovate's managing director in Taiwan，said in a statement．
    Mobiles have also changed the nature of relationships，with the survey finding nearly half of all respondents use text messages to communicate．Apart from the obvious calling and texting，the top three features people use regularly on their mobile phones globally are the alarm clock，the camera and the games．As for email and Internet access，17 percent of respondents said they checked their inboxes or surfed the Web off their phones，led by those in the United States and Britain．
    "As the mobile becomes more and more an all-in-one（一体化） device，many other businesses are facing challenging times．The opportunities for mobile manufacturers and networks however are enormous，"said Synovate's global head of media，Steve Garton．
