Americans still have been gaining weight,although they have cut their average fat intake from 36 to 34 percent of their total diets in the past 15 years.Indeed,cutting fat to control or lose weight makes sense. Fat has nine calories per gram. Protein and carbohydrates（碳水化合物）which break down into amino acids and simple sugars respectively,have just four. Moreover,the body uses fewer calories to metabolize（新陈代谢）fat than it does to metabolize other foods.
But cutting fat from your diet doesn't necessarily mean your body won't store fat. For example, between nonfat and regular cookies,there's trivial difference in calories because manufacturers make up for the loss of fat by adding sugar. Low-fat crackers,soups and dressings can also be just as high in calories as richer versions.No matter where the calories come from,overeating will still cause weight gain.The calories from fat just do it a little quicker. A Wisconsin computer programmer who decided with a diet coach to eat only 40 grams of fat a day learned the lesson firsthand.He wasn't losing weight.Then he showed his food diary to his coach and revealed he'd been eating half a pound of jelly beans a day."They don't have any fat,"he explains.But they had enough sugar to keep him from losing an ounce.
Nonfat foods become add-on foods.When we add them to our diet,we actually increase the number of calories we eat per day and gain weight. That was born out in a Pennsylvania State University study.For breakfast,Prof. Barbara Rolls gave two groups of women yogurt that contained exactly the same amount of calories.One group's yogurt label said"high fat”一the other,"low fat". The"low fat"yogurt group ate significantly more calories later in the day than the other group. "People think they've saved fat and can indulge themselves later in the day with no adverse consequences,"says Richard Mattes,a nutrition researcher at Purdue University."But when they do that,they don't compensate very precisely,and they often end up overdoing it."

Americans are still gaining weight though reducing the fat intake because_________.
A:they eat regular cookies instead of nonfat ones
B:they eat too much
C:they eat too much sugar
D:they eat low-fat crackers,soups

答案：B

主旨推断题。本文第一句就说：虽然美国人减少了脂肪摄入量，但是体重却没有停止增加。接下来就详细分析了为何如此：很多人认为自己选择了低脂或无脂肪食物就会放松警惕，放纵自己吃很多，而这些无脂肪食物中往往添加了很多东西来弥补脂肪的缺失，这样一来导致肥胖问题并没有减轻。因此本题选B。
本题是细节考查题。根据第一段第三句和第四句可知：每克脂肪含9卡路里热量，而protein and carbohydrates则含4卡路里热量，因此本题选C。 B选项“sugar”和D 选项“amino acids”为protein and carbohydrates分解后的产物。
本题是推断题。第二段倒数第二句中强调这个电脑程序员每天吃half a pound of jelly beans，这里从这一非常具体的数据half a pound中可以推断出他吃得太多了。因此选D。
本题是推断题。根据第三段中芭芭拉教授的实验，我们得知食用低脂酸奶的那一组体重增加反而高于食用高脂酸奶的那组，因为食用低脂酸奶的人认为自己摄入了较少的脂肪，因此在接下来的一天中就会吃很多别的东西，往往导致体重增加。根据第三段可知两组女性所吃的酸奶卡路里相同（that contained exactly the same amount of calories），并非哪个热量多哪个少，也并非说吃了同等数量的酸奶，因此选项B和C都不对。实验结果表明食用低脂酸奶的人反而体重增加，因此D选项不对。本题只能选A。
文中第一句话就说：即使减少脂肪摄入量，肥胖依然是美国人面临的一个问题，以及接下来所举的例子都说明了通过摄入低脂食物的方法未必能减肥，因此选项A和D 都不对。通过第一段第三和第四句可知：美国人认为有必要知道各种食物所含热量，由此来决定食用什么以及多少食物。因此可推断选项C是正确的。

Losing Weight
Girls as young as 10 years old are dieting and in danger of developing unhealthy attitudes about weight,body image and food,a group of Toronto researchers reported Tuesday.
Their study of 2,279 girls aged 10 to 14 showed that while the vast majority had healthy weights,nearly a third felt they were overweight and were trying to lose pounds. Even at the tender age of 10,nearly 32 percent of girls felt"too fat"and 3 1 percent said they were trying to diet.
McVey,a researcher at the Hospital for Sick Children in Toronto,and her colleagues analyzed data collected in a number of surveys of southern Ontario school girls between 1993 and 2003,reporting their findings in Tuesday's issue of the Canadian Medical Association Journal.
Nearly 80 percent of the girls had a healthy body weight and only 7.2 percent were considered overweight using standard weight-to-height ratios.Most researchers suggest the rate of overweight children in this country is several times higher than that figure.
Nearly 30 percent of the girls reported they were currently trying to lose weight,though few admitted to dangerous behavior such as self-induced vomiting.
Still,a test that measured attitudes towards eating showed 10.5 percent of survey participants were already at risk of developing an eating disorder.
"We're not talking about kids who've been prescribed a diet because they're above average weight or overweight. We're talking about children who are within a healthy weight range.And they have taken it upon themselves to diet to lose weight,"McVey said,acknowledging she found the rates disturbing. She said striking a balance between healthy weights and healthy attitudes towards food and body image is a complex task,with no easy solutions.

What kind of institution does the lead researcher work with?
A: A school.
B: A hospital.
C: An association.
D: A charity.

答案：B

解析：

文章第二段中的第一句和第四段中的第-句先后提到，接受调查的女孩中的绝大多数体重都在健康范围内。

文章的第三段提到，主要研究人员McVey女士在一家医院工作。

文章的第六段提到，有关体重、体形和饮食等的不健康态度使得一些女孩子面临饮食失调的危险。

单选题

Which of the following ways of losing weight is mentioned in the news item?

A

Using cars less.

B

Using stairs rather than lifts.

C

Exercising more and eating less.

正确答案： B

解析：新闻结尾处提到…governments must encourage people to get out of their cars.因此，此题答案选A。
【录音原文】
　　The scale of the obesity epidemic is such that the world needs a global pact on the best ways to tackle it. At present, according to Professor Philip James, an expert on nutrition, obese children outnumber the malnourished by two to one. This worldwide weight gain is sparking a marked rise in some diseases—the number of people with type two diabetes is expected to double to 366 million by 2030. According to Professor James, there is no point in blaming individuals for being overweight—we need real political leadership to change the environment that is rapidly making the world fat. The fat content of food needs to be labelled clearly, advertisers must be prevented from targeting children and governments must encourage people to get out of their cars.

　　W：John, we’ve got to go on a diet!
　　M：Oh, no, not again. It never works for me.
　　W：It would work if you listened to me and made an effort.
　　M：All right, what is it this time?
　　W：Well, first of all, we should plan a balanced diet. We should make sure that we’re getting all the necessary vitamins and minerals and things like that.
　　M：That sounds like homework!
　　W：Don’t worry. I’ve got a list of all things here and loads of recipes for all sorts of meals. Secondly, we shouldn’t try to lose weight quickly. It doesn’t work, because you lose energy and feel hungry all the time. I think it’s better to feel good and lose weight slowly.
　　M：So how long is this diet going to go on?
　　W：Until we feel we’re the right weight! Maybe each of us should give up something that is bad for us. You know, I should give up cakes and you should give up sugar in tea and coffee.
　　M：Ugh

◆Topic 9：Keeping Variety of Language and Culture　　Questions for Reference:　　1) What is the reason for losing a variety of language and culture?　　2) What are the solutions to the problem of languages and culture dying?　　3) What’s the most important thing we should do to save our language and cult/are from now on?

正确答案：【参考答案】
Nowadays, international communication has become more and more important, people prefer to communicate in languages, such as English, Arabic and Chinese. But many of the world’s languages and culture are dying out. In my presentation I will examine the problem of languages and culture, dying and the solutions, such as writing books and increasing language population levels.
Firstly, as the technology improves, people around the world are relying more and more on electronic devices to communicate with each other. While this trend is helping the major culture, it is having a harmful effect on the minor culture that could be swallowed up by the major culture.
Secondly, some of the world’s languages are not being learned widely by children or used in daily commerce. In some boarding schools, children were punished for speaking their parent’s language. Despite the desires of language and culture activists, the outlook is somewhat grim.
People already realize this problem exists and are trying to solve it. For one solution, people can record the culture and languages on books or tapes, making sure our descendants can learn or use them in the future.
The second solution is increasing the language population levels. Governments can make some policies, like encouragement for people to learn and teach the languages facing extinction, no matter whether the language is used in daily commerce or not. By trying to keep them alive, at least they have a future as second languages.
The important thing is to learn the elder’s tongue and culture before it’s too late. Otherwise we will lose them.
