问题     If you put water on the stove and heat it up, it will at first just get
hotter and hotter. You may then conclude that heating water results only
in hotter water. But at some points everything changes—the water starts【S1】_____________
to boil, turned from hot liquid into steam. Physicists call this a "phase【S2】_____________
transition".
    Automation, driven by technological progress, has been increasing
inexorably for the past several decades.  Two schools of economical【S3】_____________
thinking have for many years been engaged in a debate about the
potential  effects  of  automation  on jobs,  employment  and  human
activity: will new technology spawn on mass unemployment, as the【S4】_____________
robots take jobs away from humans? Or will jobs robots take over release【S5】_____________
or unveil—or even create—demand for new human jobs? The debate has
flared up again recently because technological achievements such as deep【S6】_____________
learning, which recently enabled a Google software program called
AlphaGo to beat Go world champion Lee Sedol, a task considered even
hard than beating the world’s chess champions.【S7】_____________
    Ultimately the question boils down to it:  are today’s modern【S8】_____________
technological innovations like those of the past, which made obsolete the
job of buggy maker, but created the job of automobile manufacturer? Or
is there  something about today  that is marked different?  Malcolm【S9】_____________
Gladwell’s book The Tipping Point highlighted what he called "that
magic  moment  when  an  idea,  trend,  or  social  behavior  cross a【S10】____________
threshold, tips, and spreads like wildfire". Can we really be confident
that we are not approaching a tipping point, a phase transition—that we
are not mistaking the trend of technology both destroying and creating
jobs for a law that it will always continue this way?
【S3】
选项
答案economical—economic
解析 词义混淆。此处意为“多年以来，经济学思想的两个流派就自动化对工作、就业和人类活动的潜在影响这一问题进行了激烈的讨论”。economic意为“经济(上)的，产生经济效益的”，而economical意为“节俭的，经济的”，不符合句意，故将economical改为economic。
