【題目】根據(jù)短文內(nèi)容，從短文后的選項(xiàng)中選出能填入空白處的最佳選項(xiàng)。選項(xiàng)中有多余選項(xiàng)。

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】

試題分析：本文屬于說明文，很多人都喜歡減肥，喜歡不斷地在體重計(jì)上量自己的體重，本文介紹了五種體重計(jì)計(jì)量不準(zhǔn)確的情況。

【1】G 根據(jù)橫線前句They found that people’s weight changed considerably throughout the week.人們的體重在一周的不同時(shí)間中是不一樣的。那么橫線句內(nèi)容應(yīng)該與之相關(guān)，G項(xiàng)“Many people were heaviest on Mondays and lightest on Fridays.”說明的正是一周不同時(shí)間，人們的體重不一樣的情況。故G項(xiàng)符合上下文串聯(lián)。

【2】A 根據(jù)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.可知很多人在計(jì)算體重的時(shí)候，把衣服的重量也計(jì)算在內(nèi)了。所以A項(xiàng)“You miscalculate your clothing你錯(cuò)誤計(jì)算了你的衣服.”符合上下文串聯(lián)。

【3】D 根據(jù)橫線前句You’ve heard that muscle is denser (密度大的) than fat.在人體中肌肉的密度比脂肪更大。說明本段涉及這兩種物質(zhì)的比較，D項(xiàng)“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間”介紹的是這兩種物質(zhì)的比較，符合上下文串聯(lián)。

【4】B 根據(jù)橫線前句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，你的體重會(huì)有明顯增加。但是不要擔(dān)心，那樣的體重只是暫時(shí)的，并不是你真正的重量。故B項(xiàng)正確。

【5】E 根據(jù)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 .可知如果你在鍛煉以后再去量體重，你會(huì)發(fā)現(xiàn)自己體重變輕了。所以如果你想繼續(xù)把體重減下去，你跳上體重計(jì)，用這樣的重量去激勵(lì)自己。故E項(xiàng)正確。
