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.
The word "leapfrogged" in paragraph 1 most probably means that______.
选项 A、cell phone technology is rapidly becoming obsolete
B、cell phone users communicate by jumping over normal phone lines
C、cell phone use is expanding at a rapid rate
D、cell phone use has replaced and surpassed traditional phone use
答案D
解析 属词义推断题。由leapfrogged(是个复合词由leap“跳跃”+frog“青蛙”+ged．“过去分词的后缀”组成，由此可推测此词的字面意思是“像青蛙一样跳跃”)所在的上下文(第一段第三句)可知：在工业化的西方国家，手机的使用已leapfrogged，传统的电话网络阶段……。下文指出：像柬埔寨这样的穷国，就可以直接迈向无线通讯。由此可知，选项D正确(手机的使用已经取代并跨越了传统的电话)。选项A、C无法从文中推出。选项B是利用leapfrogged的字面意思编造的干扰项。
