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. advise readers to buy books
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

高三英语阅读理解中等难度题查看答案及解析
Death is natural, but do you have any idea of the process of dying? Modern scientists divide the process of dying into two phases --- clinical or temporary death and biological death.Clinical death occurs when the vital organs, such as the heart or lungs, have ceased to function, but have not suffered permanent damage.The organism can still be revived(复活).Biological death occurs when changes in the organism lead to the “breaking up” of vital cells and tissues.Death is then unchangeable and final.
Scientists have been seeking a way to prolong the period of clinical death so that the organism can remain alive before biological death occurs.The best method developed so far involves cooling of the organism, combined with narcotic sleep.By slowing down the body’s metabolism(新陈代谢), cooling delays the processes leading to biological death.
To illustrate how this works, scientists performed an experiment on a six-year-old female monkey called KetA. The scientist put Keta to sleep with a narcotic. Then they surrounded her body with ice-bags and began checking her body temperature.When it had dropped to 28 degrees the scientists began draining blood from an artery.The monkey’s blood pressure decreased and an hour later both the heart and breathing stopped: clinical death set in.For twenty minutes Keta remained in this state.Her temperature dropped to 22 degrees.At this point the scientists pumped blood into an artery in the direction of the heart and started artificial breathing.After two minutes Keta’s heart became active once more.After fifteen minutes, spontaneous(自发的)breathing began, and after four hours Keta opened her eyes and lifted her head. After six hours, when the scientists tried to give her a penicillin injection, Keta seized the syringe and ran with it around the room.Her behavior differed little from that of a healthy animal.
1.For a person who suffers from the clinical death, _________.
A. his most important organs are damaged.
B. he still has the possibility of getting back to life.
C. he cannot avoid final death.
D. he is still very much alive
2.Scientists try to make the time of clinical death longer in order to __________.
A. slow down the body’s metabolism.
B. bring vital cells and tissues back to active life.
C. cool the organism.
D. delay the coming of biological death.
3.How did the scientists put Keta into clinical death?
A. By putting her to sleep, lowering her temperature and draining her blood.
B. By surrounding her body with ice-bags and draining her blood.
C. By lowing her blood pressure and stopping her heart from beating.
D. By draining her blood, lowering her blood pressure and stopping her breathing.
4.All of the following indicate that the monkey has almost restored to her original physical state except the fact that__________.
A. her heart beat again.
B. she regained her normal breath.
C. she rejected a penicillin injection.
D. she acted as lively as a healthy monkey.
