12．Lately，everywhere you look，people are running around with fitness trackers on their wrists．Along with a smartphone and an accompanying app，these trackers can report how many calories you've burned and the distance you've traveled．Still curious about yourself？You can also learn the number of stairs you've climbed and steps you've taken，metrics（度量）it had never occurred to me to wonder about．
Not one to resist peer pressure，however，I paid $100for a Fitbit Flex．I chose that brand on the basis of research：asking my friend Sari which tracker she used．
The Fitbit website offered instructions on setting up my new tracker．I entered my height and gender（性别）and certain information I considered none of its business：birth date and weight．Then I established goals．The American Heart Association recommends we all walk 1 0，000steps a day-about five miles，and so does Fitbit．I decided 6，000steps was a good place for me to start．
I changed my tune when，on day one，I hit 6，000steps and tiny LED lights flashed on my wristband．Confident enough now，I went back to my phone and upped my goal to 8，000steps．
OK．So I got a little obsessed（着迷）．On day five at a department store，I decided to check my progress．My target number was just 275steps away!I walked around the dress department watching my smartphone register each step I took．I hate to tell you how much pleasure this gave me．
Now I always wear my tracker，not because I've grown to love fitness but because I like being trendy and self-absorbed．Last night I was leaving a restaurant when Fitbit emailed to congratulate me on walking more than 10，000steps．Who wouldn't love a tool that turns your every footstep into an accomplishment？

分析 本文属于记叙文阅读，作者通过这篇文章向我们讲述了如今的智能手机可以帮助我们测量自己的步数以及对卡路里的消耗，作者叙述了他自己使用这个软件的亲身效果，使读者更加了解这个软件．
解答 25．C 推理判断题，根据文章第一段Along with a smartphone and an accompanying app，these trackers can report how many calories you've burned and the distance you've traveled．我们可以判断出：人们使用这款类似的APP就是为了测量他们的步数以及对卡路里的消耗．故选C．
26．B 词义猜测题，根据第三段I entered my height and gender（性别）and certain information I considered none of its business：birth date and weight．可知我们发现生日，体重这样的信息对我们来说并没有其他信息比如证件号等来得重要，因此划线短语的意思为"不重要"，故选B．
27．C 细节理解题，根据第三段和第四段I decided 6，000steps was a good place for me to start．I changed my tune when，on day one，I hit 6，000steps and tiny LED lights flashed on my wristband．可知作者是不自信的，因为他完成了他的目标，所以他的信心才大增，因此我们能推断出刚开始作者是不自信的，故选C．
28．D 细节理解题，根据倒数第二段OK．So I got a little obsessed（着迷）．On day five at a department store，I decided to check my progress．可以判断作者对这个工具是相当满意和着迷的，故选D．
