问题     Are passwords outdated? It’s starting to seem like it. Everybody hates them, and nobody can remember all the ones they’ve【C1】________. These days a typical internet user has dozens of online accounts. If you really want to be safe, you need to have a different password for each one, and each password needs to be incredibly【C2】________, with a mix of capital letters,【C3】________, and numbers. Who can keep all that stuff in their head?
    Most people don’t【C4】________. Some just make up one password and use it everywhere while others might have a few passwords for different usages. Problem is that【C5】________one site gets attacked by hackers, they now have the password that you use elsewhere.
    In one recent attack on Sony, millions of accounts were exposed. Computer scientists realize the system is【C6】________and they’re looking for alternatives. But most【C7】________haven’t been very good. Fingerprint readers require special hardware, and smart cards can be lost or【C8】________. "We’ve tried【C9】________other approaches, but we end up back with passwords. They’re the least【C10】________in a series of bad options," says a security consultant.
    Markus Jakobsson, a veteran security researcher with a Ph. D in computer science, has come up with something he calls "fastwords." Instead of【C11】________a meaningless and obscure password, you join three simple words that come from a【C12】________known only to you. If one day you were driving to work and【C13】________a frog that ended up flat, you might choose "frog work flat."
    Some【C14】________: You  can  enter  the  three  words【C15】________any order ("flat frog work"), and the system【C16】________knows that you’re you. If you totally【C17】________, the fastword system will tell you one of the three words,  which  should enable  you to remember the【C18】________idea and thus the three keywords. Jakobsson says one large service provider is evaluating the fast-words concept.
    Fastwords【C19】________a step  in the right direction,【C20】________it’s not the promised land. Someone, somehow, needs to come up with something completely different— and radically better—than what we have today.
【C18】
选项 A、ambiguous
B、obscure
C、original
D、firsthand
答案C
解析 系统提示三个词中其中一个词，这样有助于想起当初设置这个密码时的想法，进而想起这三个快词。C项origin“最初的，原始的”符合题意，故为答案。A项ambiguous一般用来形容词义“模棱两可的”，让人困惑，有歧义。B项obscure形容语言、文体等含糊不清的。或是在视线上模糊的东西。D项firsthand“第一手的”强调的是直接、原始的，不经过他人的，一般用来形容来源、资料等。
