问题     Are passwords outdated?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.
【C6】
选项 A、rotten
B、isolated
C、outdated
D、broken
答案D
解析 从上文提到网站受到攻击，从而大量账号曝光，及下文的“他们正在寻找替代品”。可知这个系统被破解了，故答案为D项broken“被破解的。被破坏的”。A项rotten“腐烂的”一般用来形容食物、树木等物体，无法修饰电脑系统。计算机系统被攻击，系统可能会瘫痪，信息被泄漏，不会出现隔绝的情况，故B项isolated“隔离的”不太合理。根据上下文，我们只知道系统被攻击遭到破坏，无从得知系统是否过时，C项outdated“过时的”不准确。
