问题     Most people who go online have mainly positive experience. But, 【C1】______ any endeavor—traveling,cooking,or attending school— there are some risks. The online world, like the 【C2】______of society, is made up of a wide array of people. Most are【C3】______and respectful, but some may be rude and insulting,【C4】______ even mean and exploitative. Children get a lot of benefits from being online, but they can also be 【C5】______of crime and exploitation in this as in any other environment. Trusting, curious, and 【C6】______to explore this new world and the relationships it brings, children need parental【C7】______and commonsense advice.
    Although there have been some highly 【C8】______cases of abuse involving the Internet and online services, reported cases are 【C9】______ infrequent. Of course, like most crimes【C10】______ children, many cases go unreported,especially if the child is【C11】______ in an activity that he or she does not want to discuss with a parent.
    The fact that crimes are being【C12】______ online, however, is not a reason to【C13】______ using these services. To tell children to stop using these services would be like telling them to 【C14】______ attending school because students are sometimes【C15】______ there. A better strategy would be to instruct children about both the benefits and dangers of cyber space in order that they could better protect themselves in any【C16】______dangerous situation.
     【C17】______ children need a certain 【C18】______of privacy, they also need parental involvement and supervision in their daily lives. The same parenting skills that【C19】______to the "【C20】______world" also works while online.
【C12】
选项 A、committed
B、accomplished
C、achieved
D、fulfilled
答案A
解析 动词辨析题。本题四个选项都表示“完成；做”，但用法有所不同。[A]committed“犯(错误)，干(坏事)”，从句的主语是crimes，因此该项正确。[B]accomplished和[C]achieved都强调“经过努力后达成了某种目的”，与原文语境不符，故排除；[D]fulfilled强调“履行(条约、责任、诺言等)；执行(命令等)”，也与原文不符，故排除。
