Question

【題目】Does the Body Burn Fat When You Are Hungry?

Your body stores fat as a way to help protect you against starvation if you can’t take in enough food. However, your fat reserve isn’t the first place your body goes for food. Instead, it reaches out for sugar for energy. 【1】

Hunger is normally a reflection that your body has used up energy from recent food you ate and has moved onto getting energy from sugar in your blood. 【2】 The more sugar you take in, the more fuel your body has to use before it reaches out to the fat stores. If your body doesn’t have enough sugar to supply the energy it needs, it begins to burn fat when you’re hungry instead.

Missing meals and going hungry can change your metabolism (新陳代謝) so it stores fat instead of burning it. 【3】 However, if you skip meals for several days and severely lower your calorie (卡路里) intake, your body begins to store as much fat as possible.

【4】 Your body burns up sugar stored in your system and begins to burn fat as you continue to exercise. However, exercising when you’re hungry won’t help you burn fat faster. A recent study shows that the body burns the same amount of fat regardless of whether you are hungry when you exercise.

Staying hungry all day won’t necessarily help you burn fat, but cutting calories is key to losing weight. 【5】 Snack (吃點(diǎn)心) in between meals to keep your metabolism working all day, which helps it burn more fat than if it’s allowed to slow down when it’s not meal time. Snacking in between meals can help you control your meal sizes at meal time.

A. Exercise is key to burning fat.

B. You shouldn’t cut out food to cut calories.

C. This doesn’t happen in a day of missing meals.

D. Just being hungry doesn’t mean your body is burning fat.

E. If you take in less food than your body burns, you’ll lose weight.

F. Your body stores sugar in case you need it when you feel hungry.

G. Eat five or six small meals throughout the day instead of three large ones.

【解析】

本文是一篇說(shuō)明文。主要講述了人在饑餓的時(shí)候不會(huì)燃燒脂肪。

【1】考查對(duì)上下文的理解及推理判斷能力。根據(jù)上文可知，人饑餓時(shí)身體最先尋求作為能量的來(lái)源不是體內(nèi)的脂肪儲(chǔ)備而是體內(nèi)儲(chǔ)備的糖，故D選項(xiàng)Just being hungry doesn’t mean your body is burning fat. “僅僅是餓并不意味著你的身體在燃燒脂肪”符合語(yǔ)境，故選D。

【2】考查對(duì)上下文的理解及推理判斷能力。該空前一句說(shuō)到“饑餓時(shí)你的身體開始從體內(nèi)儲(chǔ)備的糖中獲得能量”，后一句說(shuō)到“糖攝入得越多，你的身體在開始消耗脂肪儲(chǔ)備前就有越多的食物可以使用”，故F選項(xiàng)Your body stores sugar in case you need it when you feel hungry. “你的身體會(huì)儲(chǔ)備糖以防你饑餓的時(shí)候需要它”符合語(yǔ)境，故選F。

【3】考查對(duì)上下文的理解及推理判斷能力。該空后一句說(shuō)到“然而，如果你連續(xù)幾天不吃東西,嚴(yán)重減少熱量的攝入，你的身體就會(huì)開始盡可能多地儲(chǔ)備脂肪”，故C選項(xiàng)This doesn’t happen in a day of missing meals. “一天不吃東西，這種情況還不會(huì)發(fā)生”符合語(yǔ)境，故選C。

【4】考查對(duì)上下文的理解及推理判斷能力。該空后一句說(shuō)到“當(dāng)你持續(xù)鍛煉的時(shí)候你的身體就會(huì)燃燒儲(chǔ)存在你身體里的糖并開始燃燒脂肪”，由此可推斷出，A項(xiàng)Exercise is key to burning fat. “鍛煉是燃燒脂肪的關(guān)鍵”符合語(yǔ)境，故選A。

【5】考查對(duì)上下文的理解及推理判斷能力。該空前一句說(shuō)到“一整天都保持饑餓不一定可以幫助你燃燒脂肪，但是減少熱量是減重的關(guān)鍵”后一句說(shuō)到“在兩頓飯之間吃些點(diǎn)心可以幫助你燃燒更多的脂肪”，故B選項(xiàng)You shouldn’t cut out food to cut calories. “你不應(yīng)該為了減少熱量就減少食物”符合語(yǔ)境，故選B。

七選五題型考察學(xué)生把握整篇文章的布局和邏輯層次關(guān)系和把握微觀信息間關(guān)聯(lián)性這種題一般可從以下方面來(lái)做：

（1）看首段，跳過(guò)空格快速通讀全篇，確定文章體裁，抓住文章結(jié)構(gòu)，分析篇章結(jié)構(gòu)，了解文章大意。首段的末句一般是全文的主題所在，首段的末句對(duì)于快速掌握文章的主題具有重要意義。

（2）精讀空格前后兩句，利用各種銜接手段選擇正確的選項(xiàng)填入空格。七選五空出的是整個(gè)句子，可以通過(guò)選項(xiàng)中某個(gè)名詞或動(dòng)詞跟空前或空后的一致性或者相關(guān)性來(lái)確定這兩個(gè)句子之間有一種關(guān)聯(lián)性，從而選擇正確的答案。如第5題，該空前一句說(shuō)到“一整天都保持饑餓不一定可以幫助你燃燒脂肪，但是減少熱量是減重的關(guān)鍵”后一句說(shuō)到“在兩頓飯之間吃些點(diǎn)心可以幫助你燃燒更多的脂肪”，故B選項(xiàng)You shouldn’t cut out food to cut calories. “你不應(yīng)該為了減少熱量就減少食物”符合語(yǔ)境，故選B。

（3）解題的關(guān)鍵是能嫻熟地利用各種銜接手段。尤其要注意代詞，連詞等。如表示轉(zhuǎn)折關(guān)系的but，though, however 等。

最后，用代入法，檢查答案是否合理，將所有選擇答案放回空白處，通讀全文，檢查文章內(nèi)容是否語(yǔ)義連貫合理、緊扣主題，語(yǔ)篇結(jié)構(gòu)是否通順連貫、具有一致性、合乎邏輯，寫作思路是否清晰明了，格式以及用語(yǔ)是否恰當(dāng)貼切，從而判斷選擇的答案是否正確。
