问题 Passwords are a pain in the ass. They’re either easy to【C1】______ or hard to remember, and when breaches (破坏)【C2】______ you have to come up with a whole new one. So people are trying to do away with passwords altogether, and so far fingerprint scanners are doing the job nicely.
Still, fingerprints alone are not【C3】______ . Online security has become【C4】______ important, forcing service providers to come up with better measures such as two-factor authentication (验证) to【C5】______ user information. Companies are turning to other parts of our bodies to find biometric (生物计量的)【C6】______ that are up to the task, and our faces and eyes are at the top of the list. Although facial and eye-based recognition appear gimmicky for now, they may soon become as prevalent and popular as fingerprint scanners. That pairing could root out passwords and clunky text-message two-factor【C7】______ altogether, making it a completely biometric process.
The popularity, prevalence and convenience of fingerprint scanning means it is here to stay, and by no means are face and eye recognition meant to【C8】______ it. Choudhury sees the newer method as a complement to fingerprints, providing a more convenient second-factor authentication as opposed to entering a text code sent to your phone. While the tech we have right now may not be fast or secure enough to be truly convenient and helpful, we’re getting close. Using the adoption of fingerprint scanners as a【C9】______ , Choudhury estimated we are about five years away from iris (虹膜) scanners and face detection becoming【C10】______ . Until then, we’ll have to deal with changing our crappy passwords every so often and hope we don’t forget them.
A) complements I) interfere
B) conceptions J) model
C) crack K) occur
D) defend L) replace
E) enough M) traditionally
F) identify N) verification
G) inappropriate O) widespread H) increasingly [br] 【C1】

选项

答案 C

解析通过分析句子结构可知，either…or…连接并列结构，or后面是hard to remember，那么，either后面也应该是相同的结构，即adj．+to do，空格前面已有easy to，因此空格处需要填入动词原形。前一句提到“密码是一件让人头痛的事”。本句继续指出“这些密码要么很容易______，要么很难记住”，由此可知，此处应选择能与密码搭配的动词，并且和“很难记住”一样表示弊端，备选动词中只有C)crack“破解(难题、密码)”符合语境，故为答案。
