Deborah Cohen is a senior natural scientist at the Rand Corp and the author of the book A Big Fat Crisis: The Hidden Forces Behind the Obesity Epidemic and How We Can End It. According to the book, there are lots of misunderstandings of obesity.

1. If you’re obese, blame your genes.

Obesity rates have increased. Yet, between 1980 and 2000, the number 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 self-control.

Research shows that if we are faced with too much information, we have a tendency to make poor dietary choices. Our world has become so rich in temptation that we can be led to consume too much in ways we can’t understand. Even the most vigilant(警觉的) people may not be up to the task of controlling themselves.

3. Lack of access to fresh fruits and vegetables is responsible for obesity.

Although the US Department of Agriculture estimates that fewer than 5 percent of Americans live in the “food deserts”, about 65 percent of the nation’s population is overweight or 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. But there was no significant decrease in physical activity levels as obesity rates climbed in the 1980s and 1990s. In fact, although a drop in work-related physical activity may account for up to 100 fewer calories burned, leisure physical activity appears to have increased. The problem is that we eat too much.

1.The author mentioned Deborah Cohen’s book in Paragraph 1 to _______.

A. introduce the topic

B. draw readers’ attention

C. introduce the author of the book

D. advertise the book

2.What is the relationship between obesity and the place where you eat?

A. The less you eat out, the higher rates of obesity you have.

B. The less you eat at home, the lower rates of obesity you have.

C. The more you eat out, the higher rates of obesity you have.

D. The more you eat at home, the higher rates of obesity you have.

3.What’s the best title of this passage?

A. Four misunderstandings of obesity.

B. Four rules to help you avoid obesity.

C. Obesity leads to a big fat crisis.

D. Lacking self-control leads to obesity.

试题答案

1.A

2.C

3.A

【解析】

试题分析：人们对肥胖有很多误解，产生肥胖主要是因为在外就餐多、缺乏锻炼、缺乏自我控制、水果蔬菜摄入量低。

1.1】推理判断题。根据第一段得知Deborah Cohen 的书指出我们对肥胖有很多的误解这一主题。选A。

2.2】细节理解题。根据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.得知我们在外就餐越频繁，变肥胖的几率就越大，因为饭店提供的卡路里要比在家里准备的食物含量高得多。选C。

3.3】最佳标题。第一段就提到我们对肥胖有很多误解。下文从四点具体描述。因此选A。

考点：健康类文章
