单选题 Given the advantage of electronic money, you might think that we should move quickly to the cashless society in which all payments are made electronically【C1】______, a true cashless society is probably not around the corner. Indeed, predictions have been【C2】______for two decades but have not yet come to fruition. For example, Business Week predicted in 1975 that electronic means of payment would soon "revolutionize the very【C3】______of money itself," only to【C4】______itself several years later. Why has the movement to a cashless society been so【C5】______in coming? Although electronic means of payment may be more efficient than a payments system based on paper, several factors work【C6】______the disappearance of the paper system. First, it is very【C7】______to set up the computer, card reader, and telecommunications networks necessary to make electronic money the【C8】______form of payment. Second, paper checks have the advantage that they【C9】______receipts, something that many consumers are unwilling to【C10】______. Third, the use of paper checks gives consumers several days of "float" — it takes several days【C11】______a check is cashed and funds are【C12】______from the issuer's account, which means that the writer of the check can earn interest on the funds in the meantime.【C13】______electronic payments are immediate; they eliminate the float for the consumer. Fourth, electronic means of payment may【C14】______security and privacy concerns. We often hear media reports that an unauthorized hacker has been able to access a computer database and to alter information【C15】______there. The fact that this is not an【C16】______occurrence means that dishonest persons might be able to access bank accounts in electronic payments systems and【C17】______from someone else's accounts. The【C18】______of this type of fraud is no easy task, and a new field of computer science is developing to【C19】______security issues. A further concern is that the use of electronic means of payment leaves an electronic【C20】______that contains a large amount of personal data. There are concerns that government, employers, and marketers might be able to access these data, thereby violating our privacy.

【正确答案】 A

【答案解析】解析：本题考查逻辑关系(However转折；Moreover递进；Therefore结果；Otherwise对比)。逻辑关系必有上下文语义暗示。we should move quickly to the cashless society(我们可能应该迅速步入一个无现金社会)，而空后为a true cashless society is probably not aroundthe corner(一个无现金社会不太可能马上出现)，两者之间出现了明显的转折关系，因此只有however符合题意。

【正确答案】 D

【答案解析】解析：本题是对语义及词类的综合考查(reward奖励；resist抵抗；resume重新开始，继续；reverse颠覆)。此处便从上下文寻求语义。空格前的only to十分重要，表示意料之外的结果，即转折的含义，例如He lifted the stones only to hit himself．搬起石头(却)砸自己的脚。因此顺承语义，上文扬言有革命性的改变，only to(却)没实现，自食其言。空格后的it指代的预言内容。因此只有reverse符合语义，表示“把预言推翻了”。

【正确答案】 B

【答案解析】解析：本题是对语义及词类的综合考查(imaginative虚构的，富于想象力的；expensive昂贵的：sensitive灵敏的，易受影响的；productive富有成效的)。此处形不成固定搭配，由上下文语义线索来解题p有序列词(first)证明本句是主旨句的解释，即说明纸币支付方式不会消失的原因，所以内容应为推广电子支付方式的不利之处。故应选择有贬义走向的词，所以答案为B。

【正确答案】 D

【答案解析】解析：本题是对语义及词类的综合考查(similar相似的；original原始，独创的；temporary暂时的，临时的；dominant占主导地位的，支配地位的)。此处形不成固定搭配，由上下文语义来解题。expensive对应的事情是让电子货币支付成为主导地位，要成为“original”和“temporary”则不需要expensive的投入了。similar缺乏基本的评价色彩，故也不正确。

【正确答案】 C

【答案解析】解析：本题是对语义及形容词的综合考查(unsafe不安全的；unnatural不自然的：uncommon不普遍的；unclear不清楚的)。上文讲到有不法分子会侵入计算机数据库更改信息。本句进行阐述，并总结这种情况是比较普遍的，此处用了双重否定(not uncommon)。双重否定是两个表示否定意义的形式(比如否定前缀、否定后缀、否定副词等)同时使用，表示肯定的含义。

【正确答案】 A

【答案解析】解析：本题是对语义及动词的综合考查(steal窃取；choose选择；benefit有益于；return返回，报答)。本句的主语是dishonest persons，宾语是someone else's accounts(其他人的账户)，所以动词应为贬义的，只有steal符合题意。同时要注意，steal虽然为及物动词，但常常与from连用，比如steal from my wallet(偷钱包)。本题既可以用正常语言知识在解题，同时也可以根据语义走向来迅速找到答案。
