Text 4 Many people talked of the 288,000 new jobs the Labor Department reported for June,along with the drop in the unemployment rate to 6.1 percent,as good news.And they were right.For now it appears the economy is creating jobs at a decent pace.We still have a long way to go to get back to full employment,but at least we are now finally moving forward at a faster pace.However,there is another important part of the jobs picture that was largely overlooked.There was a big jump in the number of people who report voluntarily working part-time.This figure is now 830,000（4.4 percent）above its year ago level.Before explaining the connection to the Obamacare,it is worth making an important distinction.Many people who work part-time jobs actually want full-time jobs.They take part-time work because this is all they can get.An increase in involuntary part-time work is evidence of weakness in the labor market and it means that many people will be having a very hard time making ends meet.There was an increase in involuntary part-time in June,but the general direction has been down.Involuntary part-time employment is still far higher than before the recession,but it is down by 640,000（7.9percent）from its year ago level.We know the difference between voluntary and involuntary part-time employment because people tell us.The survey used by the Labor Department asks people if they worked less than 35 hours in the reference week.If the answer is“yes”,they are classified as working part-time.The survey then asks whether they worked less than 35 hours in that week because they wanted to work less than full time or because they had no choice.They are only classified as voluntary part-time workers if they tell the survey taker they chose to work less than 35 hours a week.The issue of voluntary part-time relates to Obamacare because one of the main purposes was to allow people to get insurance outside of employment.For many people,especially those with serious health conditions or family members with serious health conditions,before Obamacare the only way to get insurance was through a job that provided health insurance.However,Obamacare has allowed more than 12 million people to either get insurance through Medicaid or the exchanges.These are people who may previously have felt the need to get a full-time job that provided insurance in order to cover themselves and their families.With Obamacare there is no longer a link between employment and insurance.
Many people work parttime because they_____
A.prefer parttime jobs to fulltime jobs
B.feel that is enough to make ends meet
C.cannot get their hands on fulltime jobs
D.haven't seen the weakness of the market

Many experts believe that in the new world of artificial intelligence（AI）human beings will still be needed to do the jobs that require higher-order critical,creative,and innovative thinking and the jobs that require high emotional engagement to meet the needs of other human beings.The 1 for many of us is that we do not excel at those skills because of our natural cognitive and emotional tendencies:We are confirmation-seeking thinkers and ego-affirmation-seeking defensive reasoners.We will need to overcome those tendencies 2 take our thinking,listening,relating,and collaborating skills to a much higher level.This process of_3 begins with changing our definition of what it means to"be smart."4.many of us have achieved success 5 being"smarter"than other people as 6 by grades and test scores,beginning in our early days in school.AI will change that because there is no 7 any human being can outsmart,8.,lBM's Watson,at least without augmentation.Smart machines can process,9,and recall information faster and better than we humans.10,AI can pattern-match faster and produce a wider array of alternatives than we can.AI can even learn fasrer.In an age of smart machines,our old definition of what makes a person smart doesn't 11.What is needed is a new definition of being smart,one that 12 higher levels of human thinking and emotional engagement.The new smart will be determined not by what or how you know 13 by the quality of your thinking,listening,relating,collaborating,and learning.Quantity is 14 by quality.We will spend more time training to be open-minded and learning to update our beliefs in 15 to new data.We will practice 16 after our mistakes,and we will invest more in the skills traditionally 17 with emotional intelligence.The new smart will be about trying to overcome the two big 18 0f critical thinking and team collaboration:our ego and our fears.Doing so will make it easier to perceive reality as it is,rather than as we 19 it to be.In short,we will embrace humility.That is 20 we humans will add value in a world of smart technology,2选？

厂长:采用新的工艺流程可以大大减少炼铜车间所产生的二氧化硫。这一新流程主要是用封闭式熔炉替代原来的开放式熔炉。但是,不光购置和安装新的设备是笔大的开支,而且运作新流程的成本也高于目前的流程。因此,从总体上说,采用新工艺流程将大大增加生产成本而使本厂无利可图。总工程师:我有不同意见。事实上,最新的封闭式熔炉的熔炼能力是现有的开放式熔炉无法相比的。在以下哪个问题上,总工程师和厂长最可能有不同意见?
A.采用新的工艺流程是否确实可以大大减少炼铜车间所产生的二氧化硫?
B.运作新流程的成本是否一定高于目前的流程?
C.采用新工艺流程是否一定使本厂无利可图?
D.最新的封闭式熔炉的熔炼能力是否确实明显优于现有的开放式熔炉?
E.使用最新的封闭式熔炉是否明显增加了生产成本?

“Universal history,the history of what man has accomplished in this world,is at bottom the History of the Great Men who have worked here,”wrote the Victorian Thomas Carlyle.Well,not any more it is not.Suddenly,Britain looks to have fallen out with its favorite historical form.This could be no more than a passing literary craze,but it also points to a broader truth about how we now approach the past:less concerned with learning from forefathers and more interested in feeling their pain.Today,we want empathy,not inspiration.From the earliest days of the Renaissance,the writing of history meant recounting the exemplary lives of great men.In 1337,Petrarch began work on his rambling writing De Viris Illustribus—On Famous Men,highlighting the virtus（or virtue）of classical heroes.Petrarch celebrated their greatness in conquering fortune and rising to the top.This was the biographical tradition which Niccolo Machiavelli turned on its head.InThe Prince,he championed cunning,ruthlessness,and boldness,rather than virtue,mercy and justice,as the skills of successful leaders.Over time,the attributes of greatness shifted.The Romantics commemorated the leading painters and authors of their day,stressing the uniqueness of the artist’s personal experience rather than public glory.By contrast,the Victorian author Samuel Smiles wrote Self-Helpas a catalogue of the worthy lives of engineers,industrialists and explorers.“The valuable examples which they furnish of the power of self-help,of patient purpose,resolute working and steadfast integrity,issuing in the formation of truly noble and manly character,exhibit,”wrote Smiles,“what it is in the power of each to accomplish for himself.”His biographies of James Watt,Richard Arkwright and Josian Wedgwood were held up as beacons to guide the working man through his difficult life.This was all a bit bourgeois for Thomas Carlyle,who focused his biographies on the truly heroic lives of Martin Luther,Oliver Cromwell and Napoleon Bonaparte.These epochal figures represented lives hard to imitate,but to be acknowledged as possessing higher authority than mere mortals.Not everyone was convinced by such bombast.“The history of all hitherto existing society is the history of class struggles,”wrote Marx and Engels in The Communist Manifesto.For them,history did nothing,it possessed no immense wealth nor waged battles:“It is man,real,living man who does all that.”And history should be the story of the masses and their record of struggle,As such,it needed to appreciate the economic realities,the social contexts and power relations in which each epoch stood.For:“Men make their own history,but they do not make it just as they please;they do not make it under circumstances chosen by themselves,but under circumstances directly found,given and transmitted from the past.”This was the tradition which revolutionized our appreciation of the past.In place of Thomas Carlyle,Britain nurtured Christopher Hill,EP Thompson and Eric Hobsbawm.History from below stood alongside biographies of great men.Whole new realms of understanding—from gender to race to cultural studies—were opened up as scholars unpicked the multiplicity of lost societies.And it transformed public history too:downstairs became just as fascinating as upstairs.

陈先生:有的学者认为,蜜蜂飞舞时发出的嗡嗡声是一种交流方式,例如蜜蜂在采花粉时发出的嗡嗡声,是在给同一蜂房的伙伴传递它们正在采花粉位置的信息。但事实上,蜜蜂不必通过这样费劲的方式来传递这样的信息。它们从采花粉处飞回蜂房时留下的气味踪迹,足以引导同伴找到采花粉的地方。贾女土:我不完全同意你的看法。许多动物在完成某种任务时都可以有多种方式。例如,有些蜂类可以根据太阳的位置,也可以根据地理特征来辨別方位,同样,对于蜜蜂来说,气味踪迹只是它们的一种交流方式,而不是唯一的交流方式。以下哪项最为恰当地概括了陈先生和贾女土所争论的问题?
A.关于动物行为方式的一般性理论,是否能只基于对某种动物的研究?
B.蜜蜂飞舞时发出的嗡嗡声,是否可以有多种不同的解释?
C.是否只有蜜蜂才有能力向同伴传递位置信息?
D.蜜蜂在采花粉时发出的嗡嗡声,是否在给同一蜂房的伙伴传所在位置的信息?
E.气味踪迹是否为蜜蜂的主要交流方式?
