问题 Given the advantages of electronic money,you might think that we would move quickly to the cashless society in which all payments are made electronically.1 a true cashless society is probably not around the corner.Indeed,predictions have been 2 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 3 of money itself,"only to 4itself several years later.Why has the movement to a cashless society been so 5 in coming?Although electronic means of payment may be more efficient than a payments system based on paper,several factors work 6 the disappearance of the paper system.First,it is very 7 to set up the computer,card reader,and telecornmunications networks necessary to make electronic money the 8 form of payment Second,paper checks have the advantage that they 9 receipts,something that many consumers are unwilling to 10.Third,the use of paper checks gives consumers several days of"float"-it takes several days 11 a check is cashed and funds are 12 from the issuer's account,which means that the writer of the check can cam interest on the funds in the meantime.13 electronic payments arc immediate,they eliminate the float for the consumer.Fourth,electronic means of payment may 14 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 15 there.The fact that this is not an 16 occurrence means that dishonest persons might be able to access bank accounts in electronic payments systems and 17 from someone else's accounts.The 18 of this type of fraud is no easy task,and a new field of computer science is developing to 19 security issues.A further concern is that the use of electronic means of payment leaves an electronic 20 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.16选？A.unsafeB.unnaturalC.uncommonD.unclear
选项 A.unsafe
B.unnatural
C.uncommon
D.unclear
答案 C
解析 本题空格所在句为The fact that this is not an 16 occurrence means that dishonest persons might be able to access bank accounts in electronic payments systems。空格所在的that this is not an__16 occurrence是其前面的the fact的同位语从句，用来补充说明the fact。The fact是指上文提到黑客能够入侵电脑数据库和更改储存的信息。再联系空格后面信息，可判断出正确答案为C项uncommon“不寻常的，罕有的”。此处为双重否定表达肯定意义。意为“这种事情经常发生”。【命题思路】本题考查对上下文语义的理解，同时考查对否定含义形容词的辨析能力。【干扰排除】答案所给四个选项中，A项unsafe“不安全的，危险的”，有一定干扰强度，因为上文提到电子支付方式有不安全因素，但是空格所在句是一个否定句，双重否定表达肯定含义，若选择A，则表达含义为这种支付方式是安全的。不符合文章含义，故可排除。
