Any diet on which you live that contains fewer calories than you need to get through the day—like an 800-calorie-per-day diet—can be dangerous. Diets that don't allow any fat also can be bad for you. Everyone needs a certain amount of fat in their diet—up to 30 % of to?tal calories―so no one should eat a completely fat-free diet.

Don't have diets that restrict(限制)certain food groups, either. A diet that requires you to say no to bread or pasta or allows you to eat only fruit is unhealthy. You won't get the vitamins and minerals you need. And although you may lose weight, you'll probably gain it back as soon as you start eating normally again.

Some people start dieting because they think all the problems in their life are because of weight. Others have an area of their life that they can't control, like an alcoholic parent, so they focus on something they can control―their exercise and food intake.

People who diet may get lots of praise from friends and family when they start losing pounds, which makes them feel good. But eventually a person reaches a weight level and doesn't lose as much weight as before because the body is trying to keep a healthy weight, so they aren't any happier.

Some people may find it hard to control their eating, so they stick with an ex-treme diet for a little while, but then eat tons of food. Feeling guilty about the binge, they use laxatives('瀉藥).Eating too little to maintain a healthy weight or eating only to throw up the calories are both eating disorders, which are harmful to a person's health.

  A.  A person needs about 800 calories each day.

B.  A person who doesn't eat bread is unhealthy.

[文章大意]本文主要論述了在減肥時(shí)，為了保證身體所需的能量，要注意做到健康、均衡地飲食。

1. B細(xì)節(jié)理解題。文中第三段提到了一些人們開始減肥的原因，第四段又提到當(dāng)他們減掉體重時(shí)會得到朋友和家人的贊揚(yáng)，使他們感覺很好，因此會堅(jiān)持一段時(shí)間。而B項(xiàng)所敘述的內(nèi)容只是文中列舉的某些人生活中無法控制的事情，并不是他們減肥的原因。

2. D 詞義猜測題。根據(jù)本句后面的"…but then eat tons of food."以及最后一句"Eating too little to maintain a healthy weight…"可知答案為D項(xiàng)。

3. C細(xì)節(jié)理解題。從文中第一段可知人體每天所需要的能量要多于800卡路里，故A項(xiàng)錯誤；第一段最后一句提到脂肪占人體所需總能量的30%,并沒有說所占比例最大，因此可排除D項(xiàng)；根據(jù)第二段可知面包只是屬于某種類別的食物， 因此B項(xiàng)敘述錯誤；根據(jù)最后一段可知正確答案為C項(xiàng)。

4. C推理判斷題。根據(jù)全文內(nèi)容可知即使減肥，為了身體所需的能量必須做到健康、均衡地飲食，因此正確答案為C項(xiàng)。
