4．It's 4：50 in the morning when the alarm rings in my ears．I roll out of bed and walk blindly through the dark into the bathroom．I turn on the light and put on my glasses．The house is still as I walk downstairs while my husband and three kids sleep peacefully．Usually I go for a long run，but today I choose my favorite exercise DVD，insanity．Sweat pours down my face and into my eyes．My heart races as I force my body to finish each movement．As I near the end of the exercise，I feel extremely tired，but a smile is on my face．It's not a smile because the DVD is over，but a smile of success from pushing my body to its extreme limit．
Some people enjoy shopping，smoking，food，work，or even chocolate．But I need exercise to get through each day．Some shake heads when they see me run through the town．Others get hurt when I refuse to try just one bite of their grandmother's chocolate cake．They raise their eyebrows，surprised by my"no thank you，"or by my choice to have a salad．Over the years，I have learned it's okay to just say"no"．I shouldn't feel sorry for refusing food that I don't want to eat．
So what drives me to roll out of bed at 4：50a．m．？What gives me the reason to just say no to ice cream？Commitment．A commitment to change my life with a way that reduces daily anxiety，increases self-confidence and energy，extends life and above all improves my body shape．This is the point where a smile appears on my face as I look at myself in the mirror or try on my favorite pair of jeans that now fit just right．It's through commitment and sweat that I can make a difference within myself inside and out．

分析 本文講述了作者為了塑造一副好身材，保持體形，愉悅身心，每天早上很早起床鍛煉，還要抵御住美味的誘惑，所有這些都需要堅定的信念和意志力．
解答 25．D細節理解題．根據第一段最后一句話"It's a smile because the DVD is over，but asmile of success from pushing my body to its extreme limit．"可知作者臉上的微笑不是因為DVD的結束，而是因為一種成功的微笑，因為自己鍛煉挑戰了身體的極限．所以作者微笑是因為她有一種成就感．故選B項．
26．C 細節理解題．根據本段的"They raise theireyebrows，surprised by my‘no thank you'，or by my choice to have a salad．"從別人看到我跑步穿過城鎮搖頭；當我拒絕別人給我的可口食物時我拒絕接受，可知別人不明白她在做什么．故選A．
27．B 詞義猜測題．根據文章最后一段可知，作者每天早晨5點準時起床進行鍛煉、拒絕吃冰激凌，目的是塑造一副好身材，正是因為有了這樣一個堅定的信念才使得作者這樣堅持，所以commitment，意為"堅定的信念"．故選D．
28．C 細節理解題．根據最后一段中的"…above all improves my body shape．"可知作者加強鍛煉，克制飲食的主要目的是為了保持一個好的體型．故選A．
