Preventing obesity (肥胖) and smoking can save lives, but it doesn’t save money, reported researchers. “It was a small surprise, for it is against the common belief,” said Pieter Van Baal, who led the study. “But it makes sense. If you live longer, then you cost the health system more.”
The researchers found that from age 20 to 56, obese people racked up (累计) the most expensive health costs. But on average, healthy people lived 84 years. Smokers lived about 77 years, and obese people lived about 80 years. Smokers and obese people tended to have more heart disease than healthy people. Therefore in the long run, the thin and healthy group cost about $417, 000, from age 20 on. Smokers cost about $326, 000 and obese people $371, 000.
“The result throws a bucket of cold water onto the idea, based on guesswork, that obesity is going to cost trillions of dollars,” said Patrick Basham, a professor of health politics. “If we’re going to worry about the future of obesity, we should stop worrying about its financial impact,” he said.
“The benefits of obesity prevention may not be seen immediately in terms of cost saving in tomorrow’s budget, but there are long-term gains,” said Van Baal. “These are often immeasurable when it comes to people living longer and healthier lives.” In the meanwhile, he said that governments should recognize that successful smoking and obesity prevention programs mean that people will have a longer chance of dying of something more expensive later in life.
“Lung cancer is a cheap disease to treat because people don’t survive very long. But if they are old enough to get Alzheimer’s (早老性痴呆症) one day, they may survive longer and cost more. We are not advising that governments stop trying to prevent obesity,” Van Baal said. “But they should do it for the right reasons.”
1.Among middle-aged people, who may cost the health system most?
A. Those who are heavy smokers.
B. Those who are overweight.
C. Those who are too thin.
D. Those who are suffering from heart attacks.
2.What can we know about the belief that obesity costs much?

3.According to the text, governments prevent obesity for the purpose of _______.
A. reducing the risks of suffering cancer
B. weakening obesity’s financial impact
C. making sure of people’s long and healthy life
D. reducing the money spent on medical programs

The book A Big Fat Crisis: The Hidden Forces Behind Obesity Epidemic— and How We Can End It by Deborah Co
hen, a senior natural scientist, is very popular now. 1. But according to this book, the fo
llowing are some misunderstandings of obesity or being overweight.1．If you're obese, blame your genes.
2. Yet, between 1980 and 2000, the n
umber of Americans who are obese has doubled—too quickly for genetic factors to be responsible. At restaurants, a dollar puts more calories on our plates than ever before, because restaurant meals usually have more calories than what we prepare at home, so people who eat out more frequently have higher rates of obesity than those who eat out less.2．If you're obese, you lack selfcontrol.
Research shows that if we are faced with too much information, we have a tendency to make poor choices on diet. 3. Even, the most vigilant(警觉的)people may not be good controllers of themselves.
3．4.
Although the US Department of Agriculture estimates that fewer than 5 per cent of Americans live in the “food deserts”， about 65 per cent of the nation's population is obese. For most of us, obesity is not related to access to more fresh fruits and vegetables, but to the choices we make in supermarkets.
4．The problem is not that we eat too much, but that we don't exercise.
Michelle Obama's “Let's Move” campaign is based on the idea that if kids exercise more, childhood obesity rates will decrease. 5. In fact, although a drop in workrelated physical activity may explain up to 100 fewer calories burned, leisure physical activity appears to have increased.
A．Lack of access to fresh fruits and vegetables is a cause of obesity.
B．Obesity rates have increased.
C．Fresh fruits and vegetables we choose in a supermarket are related to obesity.
D．But there was no obvious decrease in physical activity levels as obesity rates climbed in the 1980s and 1990s.
E．People hold different views on obesity.
F．People benefit a lot from physical activities.
G．Our world has become so rich in food that we can be led to consume too much in ways we can't understand.

It is believed that around half the US adult population will be obese (肥胖的) by 2030, while one in four will fall into the severely obese category. This is according to a new study led by the Harvard T.H. Chan School of Public Health, which found that levels of obesity are increasing in every state. Indeed the predictions show that levels of severe obesity could be higher than 25 percent in half of states.
“Especially striking was our finding that among adults with very low income (less than $20,000 per year), severe obesity is predicted to be the most common in 44 states—almost everywhere in the US,” a researcher said.
The research was carried out to inform state policymakers—and perhaps help change the tendency. The study authors say the best form of attack is prevention. Limiting intake of sugar is stressed as one of the most effective and cost-effective methods for reducing obesity levels, and a tax likely to save more money than it costs.
Sugar (and the sugar industry) has come under fire for its role in promoting obesity. Indeed, one recent study published in September 2019 puts responsibility for today’s obesity epidemic (流行病) firmly on the shoulders of sugar, concluding high-sugar diets during childhood in the seventies and eighties could be behind the rise.
“We knew from previous work that obesity is increasing in the US, and that some states and demographic groups (人群) are at higher risk, but we were surprised that even the states with the lowest obesity will be above 35 percent in 2030—a level currently considered high, a researcher told Newsweek. What is clear is that we will not be able to treat our way out of this epidemic—achieving and keeping weight loss is difficult—so prevention efforts will be key to making progress in this area.”
1.What’s the most surprising finding in the study?
A.Over 25% of people will be seriously obese.
B.Levels of obesity are increasing in every state.
C.poor adults are more likely to be severely obese.
D.Half of the US adults will be overweight by 2030.
2.What is the best way to solve the problem according to the passage?
A.To reduce the tax. B.To limit intake of sugar.
C.To reduce obesity level. D.To inform policymakers.
3.What does the underlined word “fire” actually refer to in paragraph 4?
A.Blame from researchers. B.Rapid chemical change.
C.Current obesity epidemic. D.High-sugar diets.
4.What’s the main idea of the last two paragraphs?
A.Obesity is increasing everywhere in the US.
B.All states in America are at the same level of obesity.
C.Maintaining weight loss is a good way to deal with obesity.
D.Diets with less sugar are vital to preventing the problem of obesity.

Risk of death is 3.5 t0 5 times greater for obese smokers than it is for people who have never smoked and are at a normal weight, according to a study published in the November, 2006 issue of the American Journal of Preventive Medicine.
The study, which began with a self-administered questionnaire taken between 1983 and 1989, asked more than 80,000 radiologic technologists aged 22 t0 92 questions about age, height, weight and smoking behavior.
BMI (body mass index) was calculated, with a BMI of 30 t0 34.9 being considered obese, and 35 and over being very obese. Smoking behavior was analyzed by looking at a person's tobacco consumption level, number of years smoked, and current smoking status. Researchers then followed participants through December of 2002, noting the number of deaths that occurred.
The study involved researchers from the National Cancer Institute, the University of Minnesota and the American Registry of Radiolegic Technologists.
Key Findings:
20 percent of obese adults in the United States smoke.
Obese smokers face a greater risk of death from cancer and circulatory disease.
Current smoking is a greater risk factor for death by cancer than obesity is, generally speaking.
The higher a person's pack-years (number of packs smoked per day times the number of years smoked) are, the greater the risk of death.
Men and women of all ages faced an elevated risk of death due to circulatory disease as BMI increased. And for those who were both obese and currently smoking, risk of circulatory disease increased 6 to 11 times under the age of 65, as compared to their never-smoking, normal weight counterparts.
While it's not surprising that obesity coupled with smoking is a recipe for trouble, it is important to highlight this growing health concern in America today.
