本文介绍了计算机中一种可以代替密码记忆的面部识别技术。本文原文可在http://bbs.chinadaily.com.cn 中找到。

21. 答案：A

-优东公有9cc6405a法网软限科技的a655261f慧智件广升a633途元0ae1b122学得司点拨：由前文“不必记密码”和后文的“面部识别技术”可知，是“自动登录”。

22. 答案：B

点拨：因“用脸部识别技术来帮你登陆”了，所以“不需要用密码”。

23. 答案：A

点拨：“只要有一个摄象头，一张漂亮的脸蛋”，就可以“访问”你的个人电脑了。access的意思是“存取(信息) [get information from or put information into (a computer file)]”。

24. 答案：B

点拨：由confusing(令人糊涂的)可知，与之一起修饰password的应为complicated(复杂的)。

25. 答案：B

点拨：作者“作小调查研究”，就是为了搞清面部识别这种“技术”。

26. 答案：C

点拨：消费者获得到这种技术，是要通过FaceCode这种软件，而根据常识，要得到软件就得购买，要购买就涉及到价钱，因此application(应用软件)的修饰语，应为“相对便宜的”。另外，其它词与语境相差太远：independent独立的，infrequent稀少的，instant立即的。

27. 答案：D

点拨：由与前句的承接可知答案。software与前文application同义，都指“软件”。句意是：“该软件需用到一个摄像头来识别，并帮助计算机用户登陆到他们的系统当中。”

28. 答案：A

点拨：由前句中的users的提示，以及本句后面的they each have a Windows account(他们有一个Windows帐户)可知，有账户的应当是“用户”。

29. 答案：C

点拨：由下文“调出窗口用户名和密码”可知，是“系统不能识别你的脸”时候。

30. 答案：D

点拨：由上文的face recognition及全文可知，本题应填face。可将29与30两题结合起来考虑。
