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 weight diaries that 80 people kept for up to a year. They found that people’s weight changed considerably throughout the week. 【1】 Keep weigh-in days consistent for a more accurate assessment.

2. 【2】

File this one under “Yes, scientists have actually studied this.” When University of North Dakota researches 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. 【3】 If you start a strength-training routine, the number on the scale (秤) might not change, but you could still lost 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 drinking an entire water bottle’s worth, you might not like what you see. 【4】

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 . 【5】

A．You miscalculate your clothing.

B．But don’t worry, it’s just a temporary/span> 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.

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

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

Answer 1

【答案】

【1】G

【2】A

【3】D

【4】B

【5】E

【解析】

试题分析：本文属于说明文，很多人都喜欢减肥，喜欢不断地在体重计上量自己的体重，本文介绍了五种体重计计量不准确的情况。

【1】G 根据横线前句They found that people’s weight changed considerably throughout the week.人们的体重在一周的不同时间中是不一样的。那么横线句内容应该与之相关，G项“Many people were heaviest on Mondays and lightest on Fridays.”说明的正是一周不同时间，人们的体重不一样的情况。故G项符合上下文串联。

【2】A 根据本段最后一句they found that men can reduce 2.5 pounds for their clothing and women can reduce around two pounds, on average.可知很多人在计算体重的时候，把衣服的重量也计算在内了。所以A项“You miscalculate your clothing你错误计算了你的衣服.”符合上下文串联。

【3】D 根据横线前句You’ve heard that muscle is denser (密度大的) than fat.在人体中肌肉的密度比脂肪更大。说明本段涉及这两种物质的比较，D项“In fact, it takes up only about a third as much space.肌肉只有脂肪的三分之一的空间”介绍的是这两种物质的比较，符合上下文串联。

【4】B 根据横线前句So if you stand on the scale soon after drinking an entire water bottle’s worth, you might not like what you see. 可知在喝水以后，你的体重会有明显增加。但是不要担心，那样的体重只是暂时的，并不是你真正的重量。故B项正确。

【5】E 根据前句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 .可知如果你在锻炼以后再去量体重，你会发现自己体重变轻了。所以如果你想继续把体重减下去，你跳上体重计，用这样的重量去激励自己。故E项正确。
