问题     Up to 80 percent of time spent online at work is wasted, according to a new study from Kansas State University. It suggests that we spend even more time【C1】______the Internet aimlessly during our office hours than【C2】______did. " Cyberloafing(网上闲逛)"【C3】______up as much as 80 percent of the time people spend online at work, according to the study.
    Their results also suggest that【C4】______work guidelines surrounding Internet use are not enough to【C5】______worker behavior, and that if companies really want to【C6】______short the amount of time their【C7】______spend surfing the Web, they must "consistently enforce"【C8】______to uphold their cyberloafing policies. " We found that young people think that social networking is【C9】______behavior. "
    Then again, not necessarily all "cyberloafing" can be【C10】______as a net loss for businesses. A 2011 study found that in certain fields, when people spend time【C11】______browsing the Web at work, they actually【C12】______up being more productive and creative.
    The risks for employers go【C13】______lost productivity. The study pointed out that cyberloafing also【C14】______legal risks for companies, if their staff are【C15】______in activities like viewing pornography(色情)or taking part in illegal【C16】______.

" People will feel like Big Brother is【C19】______them, so companies need to be careful【C20】_______ taking those types of action," Ugrin said.
【C17】
选项 A、contain
B、maintain
C、sustain
D、obtain
答案B
解析 动词辨义题。此句意为“尽管该研究的作者支持采取更严厉的惩罚措施来保证生产效率和员工的行为表现，但他们表示雇主必须让办公环境保持健康的平衡”，maintain a balance of意为“保持……的平衡”，故maintain符合文意。contain“包含”；sustain“维持，支撑”；obtain“获得”，均不符合文意，故排除。
