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（性別）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（著迷）．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 本文屬于記敘文閱讀，作者通過這篇文章向我們講述了如今的智能手機(jī)可以幫助我們測量自己的步數(shù)以及對卡路里的消耗，作者敘述了他自己使用這個軟件的親身效果，使讀者更加了解這個軟件．
解答 25．C 推理判斷題，根據(jù)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．我們可以判斷出：人們使用這款類似的APP就是為了測量他們的步數(shù)以及對卡路里的消耗．故選C．
26．B 詞義猜測題，根據(jù)第三段I entered my height and gender（性別）and certain information I considered none of its business：birth date and weight．可知我們發(fā)現(xiàn)生日，體重這樣的信息對我們來說并沒有其他信息比如證件號等來得重要，因此劃線短語的意思為"不重要"，故選B．
27．C 細(xì)節(jié)理解題，根據(jù)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，因為他完成了他的目標(biāo)，所以他的信心才大增，因此我們能推斷出剛開始作者是不自信的，故選C．
28．D 細(xì)節(jié)理解題，根據(jù)倒數(shù)第二段OK．So I got a little obsessed（著迷）．On day five at a department store，I decided to check my progress．可以判斷作者對這個工具是相當(dāng)滿意和著迷的，故選D．
