[解析]
(1)词义猜测题。根据第一段a server message flashed on my screen,with instructions for changing it.(一条服务器消息在我的屏幕上闪现,并附有更改密码的说明。)可知,expired意为"到期了"。A.been renewed更新;B.changed改变;C.been mistaken弄错;D.become due到期。故选D。
(2)细节理解题。根据第一段Coming up with a new code doesn't seem like a big deal,unless you work at my company,where we have to change it monthly,using at least one uppercase character,one lowercase character,one symbol,and one number.(提出一个新代码似乎没什么大不了的,除非你在我的公司工作,在那里我们必须每月更改一次,至少使用一个大写字符、一个小写字符、一种符号和一个数字。)可知,作者会选择C.Course4﹩Saving作为密码,故选C。
(3)细节理解题。根据第四段My password became the indicator,which reminded me that I shouldn't let myself be a victim of my recent breakup and that I was strong enough to do something about it.(我的密码成了指示符,提醒我不要让自己成为我最近分手的牺牲品,我已经足够坚强去做些什么了。)可知,我们可以从这篇文章中推断出,作者的密码是用来提醒他重塑生活的。A.He finally recovered well from his divorce.( 他终于从离婚中恢复了过来。)符合文意,故选A。
(4)标题归纳题。根据最后一段This password was a painful one to type during that month,but doing it helped me to yell at myself in my mind as I typed that statement.It motivated me to follow my monthly goal.(在那个月里,输入这个密码是很痛苦的,但当我输入那句话时,这样做帮助我在脑海中对自己大喊大叫。它激励我去实现我的每月目标。)可知,本文主要讲述的是通过把目标设定密码来激励自己。故B.To motivate yourself by setting your goals.(通过设定目标来激励自己)符合题意。故选B。
