问题     Cell phone use has exploded in many countries, easing communication between individuals but causing social malaise as well. In the industrialized West, cell phone use has leapfrogged over conventional phone networks that relied on cumbersome telephone lines and expensive underground wiring. In some countries that lacked the infrastructure often present in developed nations. In Asian countries, especially poorer ones like Cambodia, such high infrastructure costs are being avoided by simply moving to wireless communication.
    However, even in the most modern of countries, cell phone use has proved somewhat of a novelty, one that has required a redefinition of social conventions. The ability to always be connected with another person, no matter where one travels, has led to a friction of personal space and different perceptions on the value of communication. Today, cell phone users can talk to friends, workers and family members while catching a bus, walking along the street or climbing a flight of stairs.
    But what of the people around cell phone users? Often a loud call in a movie theatre or a recital hall will bring sighs of annoyance by the audience as impatience with beeping and ringing increases. But should government step in to regulate the use of cell phones and restrict their use? Some argue that market forces are best suited to solving consumer dissatisfaction. Proponents of this perspective cite new rules in movie theatres and concert halls that require patrons to turn off their cell phones before the performance begins.
    Others, however, see a role for government in harnessing this new technology. In some states, it is now illegal to drive and talk on a mobile phone. As a response to these laws and because of the complications of performing more than one task while speaking on a cell phone, companies have developed headsets so that users can talk "hands free". Nevertheless, this solution has perhaps aggravated social friction by making cell phone use even more convenient. Many users are now seen talking to themselves—a sign not of mental instability—but of the rapid expansion of modern technology.
    Regardless of private or public restrictions on the use of cell phones, society still has a long way to go before it can truly accept and adapt to the burdens of cell phone use on third parties. Only when distinct social norms are created to deal with common cell phone use will the technology become more accepted and viewed less as an irritant.
According to the text, one unforeseen consequence of hand free use has been______.
选项 A、an increased incident of unusual behavior
B、an increase in cell phone costs
C、an increase in traffic accidents
D、a decrease in brain cancer from cell phone use
答案A
解析 属信息归纳题。题目中的关键词出现在第四段第三句：为了应对这些法律，同时也因为边打电话边做几件事比较复杂，一些公司开发出头戴式受话器，使手机用户可以“脱手”交谈。接着下文指出由此产生的影响：这种方法或许更加剧了社会摩擦，现在许多用户看上去像在和自己说话——这可不是头脑混乱的迹象——而是现代科技飞速发展的表征。由此可知，这是一种不同寻常的行为表现。因此，选项A正确，题目中的unforeseen consequence与原文中的sign是同义表达。其他选项的内容在文中都没有涉及到。
