Question

                             Five reasons your scale might be wrong

   1. You weigh yourself on different days each week.

   In a Cornell University study published last year,researchers analyzed the food and weight diaries that 80 people kept for up to a year. They found that people's weight changed considerably throughout the week. 36 Keep weigh-in days consistent for a more accurate assessment.

   2. 37  

   File this one under “Yes,scientists have actually studied this/' When University of North Dakota researchers weighed people with and without clothes at various times of the year,they found that men can reduce 2. 5 pounds for their clothing and women can reduce around two pounds,on average.

   3. You don't take muscle gain into consideration. You’ve heard that muscle is denser (密度大的) than fat. 38 If you start a strength-training routine,the number on the scale (秤) might not change,but you could still lose inches and drop a clothing size or two.

   4. You just drank a lot of water.

   It's called water weight for a reason: Drinking one pound of water can translate to about one pound of weight. So if you stand on the scale soon after drinkiag an entire water bottle's worth,you might not like what you see. 39

   5. You weigh yourself after hard exercise. 

   Compared with water weight,if you weigh in after a tiring cycling class,you may lose weight temporarily because you work up a good sweat. 40

   A. You miscalculate your clothing.

   B. But don't worry,it's just a temporary gain.

   C. Salty foods cause your body to save extra water.

   D. In fact,it takes up only about a third as much space.

   E. Jump on the scale if you need to improve confidence.

   F. You should be aware of how much water you have drunk.

   G. Many people were heaviest on Mondays and lightest on Fridays.

本文是說明文。文章介紹了秤上顯示的體重與實際體重不符的五個原因.

36. G。G項“很多人周一最重、周五最 輕”與本空上一句“人們的體重在一 周內(nèi)變化很大”相符。

37. A.根據(jù)下文的 men can reduce   2. 5 pounds for their clothing and women can reduce around two pounds …可 知，稱體重時穿不穿衣服會影響結(jié) 果，因此造成秤上顯示的體重與實際 體重不符的一個原因就是“你對衣服 (的重量) 計算有誤'

38. D.根據(jù)本空上一句內(nèi)容可知，肌肉 的密度比脂肪的大，因此同等重量的 肌肉“體積只有脂肪的三分之一”。D項中的it指代muscle。

39. B.根據(jù)下一段中的Compared with water weight,if you weigh in after a tiring cycling class,you may lose weight temporarily 可 A. 因為水增 加的重量只是“暫時的”。

40. E。根據(jù)本段內(nèi)容可知，剛鍛煉完，由 于出汗較多，體重會暫時減輕，因此 “如果你需要增加自信”，這個時候稱 體重無疑是最佳時機。
