19.The average computer user has between 5 and 15 username/password combinations to log in different kinds of accounts.Some demand you use a specific number of symbols and digits,while others require you to change your password every 60 days.The feeling of confusion resulting from memorizing these login information has grown so common that it actually has a name:password fatigue(疲勞).
Having to remember so many different passwords is annoying,but it can also be dangerous.Because it is virtually impossible to remember a unique password for each of these accounts,many people leave handwritten lists of usernames and passwords on or next to their computers.
(71)GWhile these practices make it easier to remember login information,they also make it easier for thieves to hack into accounts.
Single Sign-On (SSO) confirmation and password management software can help solve this problem.With SSO,users only need to remember one password to log in to the main system.
(72)DSSO software is typically used by large companies,schools,or libraries.
(73)EIf a user loses or forgets the password required to log in to SSO software,the user will then lose access to all of the applications linked to the SSO account.Users who rely on password management software face the same problems.
Although most websites or network systems allow users to recover or change lost passwords by providing email addresses or answering a prompt(提示),this process can waste time and cause further frustration.What is more,recovering a forgotten password is only a temporary solution.
(74)A
Some computer scientists have suggested computers rely on biometrics(生物測定學).(75)F The use of biometrics raises questions concerning privacy and can also be expensive to practice.
Software engineers and computer security experts are still searching for the cure to password fatigue.Until they find the perfect solution,however,everyone will simply have to rely on the password system currently in place.
A.It does not address the larger problem of password fatigue.
B.These software programs have been built into many major web browsers
C.The problem with password management software makes users feel powerless.
D.The SSO software then automatically logs the user in to other accounts within the system.
E.However,SSO confirmation and password management software also have drawbacks.
F.This is a method of recognizing human users based on unique traits,such as fingerprints,voice,or DNA.
G.Others solve this problem by using the same password for every account or using extremely simple passwords.
分析 本文講述了計算機用戶由于用戶名和密碼過多而記混,產生一種叫"密碼疲勞"的現(xiàn)象.如何解決這一問題,目前給出了一些方案但都不完美,需要進一步完善.
解答 71.G 根據(jù)下文"雖然這些做法更容易記住登錄信息,但是它們也使小偷更容易竊取賬戶."可知,G項"也有的人通過每一個賬戶都使用一個密碼,或者使用非常簡單的密碼這個方法來解決這個問題."符合語篇邏輯,故選G.
72.D 根據(jù)上文"With SSO,users only need to remember one password to log in to the main system."講解SSO的工作原理,下文"SSO software is typically used…"講解SSO的使用區(qū)域,與D項中的關鍵詞"The SSO software"和"the system"相呼應,故選D.
73.E 上文給出SSO的解決方案,下文主要敘述SSO軟件和密碼管理軟件的缺點,所以此處應為轉折,"…also have drawbacks"是關鍵詞,故選E.
74.A 前文提到恢復一個被忘記的密碼只是一個暫時的解決方案.A項"它沒有解決密碼疲勞的大問題"符合語境,故選A.75.F 根據(jù)上文中的"biometrics(生物測定學)"可知,它涉及到指紋,DNA等.故選F.
點評 該類題型要求從短文后的七個選項中(均為完整的句子)選出五個能填入文章空處的最佳選項,主要考查考生對文章的整體內容和結構以及上下文邏輯意義的理解和掌握.分析篇章結構,把握全篇文脈是解題的關鍵.
