17．Why texting harms your IQThe regular use of text messages and e-mails can lower the IQ more than twice as much as smoking marijuana （大麻）．That is the statement of researchers who have found that tapping away on a mobile phone or computer keypad or checking for electronic messages temporarily knocks up to 10points off the user's IQ．This rate of decline in intelligence compares unfavorably with the four-point drop in IQ associated with smoking marijuana，according to British researchers，who have described the phenomenon of improved stupidity as"infomania"．The research conducted by Hewlett Packard，the technology company，has concluded that it is mainly a problem for adult workers，especially men．It is concluded that too much use of modern technology can damage a person's mind．It can cause a constant distraction of"always on"technology when employees should be concentrating on what they are paid to do．Infomania means that they lose concentration as their minds remain fixed in an almost permanent state of readiness to react to technology instead of focusing on the task in hand．The report also added that，in a long term，the brain will be considerably shaped by what we do to it and by the experience of daily life．At a microcellular level，the complex networks of nerve cells that make up parts of the brain actually change in response to certain experiences．
Too much use of modern technology can be damaging not only to a person's mind，but to their social relationship.1100 adults were interviewed during the research．More than 62 percent of them admitted that they were addicted to checking their e-mails and text messages so often that they scrutinized work-related ones even when at home or on holiday．Half said that they always responded immediately to an email and will even interrupt a meeting to do so．It is concluded that infomania is increasing stress and anxiety and affecting one's characteristics．Nine out of ten thought that colleagues who answered e-mails or messages during a face-to-face meeting were extremely rude．
The effects on IQ were studied by Dr．Glenn Wilson，a psychologist at University of London．"This is a very real and widespread phenomenon，"he said．"We have found that infomania will damage a worker's performance by reducing their mental sharpness and changing their social life．Companies should encourage a more balanced and appropriate way of working．"

A．has a positive influence on one's IQ
B．results in the change of part of the brain
C．lies in the problem of lack of concentration
D．is caused by too much use of modern technology

2．As we head from spring into summer，many college students are planning their vacations while those looking to get their first taste of the working world are likely hunting for internships（实习）．
It is estimated that U．S．companies hire about 1.5 million interns each year，half of them on an unpaid basis．Working for free might not be a big deal for some who are just grateful to have their foot in the door，but a class-action lawsuit（诉讼）led by interns who worked on the set of the 2010 film，Black Swan，could change that way of thinking and have far-reaching implications．The plaintiffs（原告） want back pay for their work and seek to prevent the film's producer，Fox Searchlight，from using unpaid interns in the future．
However the lawsuit goes，it could say a lot about how companies should value the work of interns and whether interns have a right to a paycheck like employees．It's perfectly reasonable for interns to be paid．Salaries for living expenses are only fair，especially for young people from low-income households，who may not otherwise be able to afford an unpaid internship．Paying interns also helps employers draw better talent，such as at Google （GOOG），which actively recruits interns and pays them handsomely for working on substantive projects．
Nevertheless，it would be wrong to elevate the fight over intern pay to the level of seriousness accorded to the ongoing debate over raising the federal minimum wage．For the most part，internships are training wheels，and the rules applied to them shouldn't be the same as a regular job．The decision to pay interns should really be at the discretion of employers-not a matter of law．
This is simply because there are many benefits to internships，regardless of whether it's paid or not； and at times，interns get a lot more out of the internship than the companies they intern for．The biggest benefit is pure work experience．Interns often gain valuable insight into industries and careers that they're looking to pursue in the future．
Internships also teach work ethic，which young people don't necessarily pick up in school．Lessons such as humility，the acceptance that no task is beneath one's dignity，and recognition of the chain of command，are all important to learn before a young person is ready to enter a competitie workforce．
Another thing to consider：A simple tenet of the business world is that the more you get paid，the less runway you have to"learn"your job．Interns，especially unpaid ones，are rarely held to the same rigorous standards during the interview process or in the workplace as actual employees are．The expectations of interns in general are lower，and tolerance for mistakes is higher．That's to the benefit of young people，who need time，training，and patience to reach the level of skill that businesses require．
The danger with filing lawsuits to squash unpaid internships is that many companies，either due to budgetary constraints or simply as a philosophy，may curtail or even kill their internship programs in response．
And while businesses would certainly be worse off without interns，the reverse holds true as well．Without these programs，many young men and women would lose the chance to learn important lessons about work and life that could prepare them for the next step in their development．It is an essential part of our social contract that should be maintained
