C.O.P.D(慢性障碍性肺病) blocks air flow through the lungs. It makes breathing difficult. The leading cause of C.O.P.D. is cigarette smoking. Experts at the National Institutes of Health in the United States say there is no cure to the damage to the lungs.
Dawn Demeo is an assistant professor at Harvard Medical School in Boston, Massachusetts. She said, “By 2020, C.O.P.D. may be the third leading cause of death across the world.”
C.O.P.D. is a new name for emphysema(肺气肿) and chronic bronchitis(慢性支气管炎). These are the two most common forms of the disease. Many people with C.O.P.D. have both of them. And Doctor Demeo says more women than men now die from the disease.
She is the lead author of a study by a team from Harvard’s Brigham and Women’s Hospital and the University of Bergen in Norway. The new study adds to findings that women may be more at risk than men from the damaging effects of smoking.
The team examined results from a Norwegian study of 954 people with C.O.P.D. Inga-Cecilie Soerheim co-wrote the team’s findings. Doctor Soerheim says they show that women suffered the same level of C.O.P.D.as men. But the female smokers were younger and had smoked a lot less.
The team also looked at two groups among the people in the study. These were people under the age of 60 and those who had smoked for less than 20 years. In both cases, women had more serious C.O.P.D. and a greater loss of lung function (功能)than men.
【小题1】Which of the following statements about C.O.P.D is NOT true ______.
A. Cigarette smoking is likely to cause C.O.P.D.
B. C.O.P.D. makes it hard for a person to breathe
C. C.O.P.D will be one of the most life-threatening diseases.
D. Many people with C.O.P.D. have either emphysema or chronic bronchitis.
【小题2】It can be known from the study that_____.
A. female smokers die faster than male ones.
B. women are more likely to suffer from the damaging effects of smoking than men.
C. women who suffer the same level of C.O.P.D as men were older and weaker.
D. in the group of people under the age of 60, men suffered more from C.O.P.D than women.
【小题3】Which of the following can be the best title for the passage?
A .Smoking Kills
B. Smoking Triggers Diseases
C. The Leading Causes of C.O.P.D.
D. Women Suffers More from C.O.P.D. than Men

In the Caucasus region of Russia, nearly 50 out of every 100,000 people live to celebrate their 100th birthday, and many don’t stop at 100! By comparison, in America only 3 people in 100,000 reach 100. But these Russian old people aren’t alone. The Pakistanis, who live high in the Himalaya Mountains, and the Ecuadorans of the Andes Mountains seem to share the secret of long life, too.
These people remain healthy in body and spirit despite the passage of time. While many older persons in industrial societies become weak and ill in their 60s and 70s, some Caucasians aged 100 to 140, work in the fields beside their great-great-grandchildren. Even the idea of aging is foreign to them. When asked “at what age does youth end?”most of these old people had no answer. Several replied, “Well, perhaps at age 80.”
What accounts for this ability to survive to such old age, and to survive so well?First of all, hard physical work is a way of life for all of these long-lived people. They begin their long days of physical labor as children and never seem to stop. For example, Mr . Rustam Mamedov is 142 years of age. His wife is 116 years old. They have been married for 90 years. Mr. Mamedov has no intention of retiring from his life as a farmer. “Why?What else would I do?”he asks. All these people get healthful rewards from the environment in which they work. They all come from mountainous regions. They live and work at elevations of 1,660 to 1,000 meters above sea level. The air has less oxygen and is pollution-free. This reduced-oxygen environment makes the heart and blood vessel(血管) system stronger.
Another factor that may contribute to the good health of these people is their isolation. To a great extent, they are separated from the pressures and worries of industrial society. Inherited factors also play some role. Most of the longest-lived people had parents and grandparents who also reached very old ages. Good family genes may, therefore, be one factor in living longer.
【小题1】The example of Mr. and Mrs. Mamedov implies that some Caucasians aged 100 to 140 ____.
A.become weak and hopeless |
B.are too old to work in the fields |
C.benefit from physical work |
D.are still working in the fields |
A.Retiring from their lives as farmers. |
B.Having been married for 90 years. |
C.Hard physical work. |
D.Having no intentions. |
A.Clean mountain air. |
B.Daily hard work. |
C.Good genes |
D.Stress and pressure. |

Europe’s deadly outbreak of a rare form of E. coli bacteria (大肠杆菌) has brought new attention to food safety issues. One of the problems when people get sick from food is that the simplest question is often difficult or even impossible to answer. Just what did the people eat that made them sick?
Of course, one way to avoid these medical mysteries is to keep dangerous organisms out of the food supply. This is easier said than done, but scientists keep looking for new ways.
Scientists in the United States have developed an experimental system that uses a high-tech optical scanner. The system is designed to identify the presence of contaminants(致污物) like soil or animal waste on fresh produce. These can be sources of E. coli. E. coli bacteria naturally live in the intestines(肠) of humans and many animals. Most kinds of E. coli are harmless but some can make people sick.
The new scanner can also show damage and imperfections that might make the produce unappealing to shoppers.
Scientists designed the system at a Department of Agriculture research center in Beltsville, Maryland. Moon Kim of the Agricultural Research Service led the team.
MOON KIM: “We were requested, we were asked, to develop a method to detect contamination in produce. So we started with the apple as the model sample.”
The scanner uses a high-speed camera placed over the conveyer belt that moves the produce along. As the apples move along the belt, the scanner captures images of each piece of fruit.
Moon Kim says the team hopes the system will be available before long.
MOON KIM: “We are targeting for development in commercial plants for the next several years.”
The scanner can direct a sorting machine to separate the bad apples from the good ones. The system is currently able to show the surface of only half the apple as it speeds by. The inventers hope to improve the process so it can show the whole surface.
【小题1】What is the main topic of the text?
A.Bacteria. | B.A high-tech scanner. |
C.A camera | D.Food safety. |
A.broke out all over the world | B.comes from soil or animal waste |
C.is extremely harmful to health | D.does not cause illness |
A.can help to sort out different fruits |
B.make the produce appeal to shoppers |
C.can only capture images of the whole apple |
D.can identify the presence of contaminants |
A.The scanner needs to be improved. |
B.The scanner will be available in the next several years. |
C.Moon Kim is unwilling to develop the scanner. |
D.The scanner is connected to a sorting machine. |

Studies show that children who eat breakfast do better in school. It doesn’t take much further thought to know that adults will feel better and do better at work as well. Whether you work at home, on the farm, at the office, at school, or on the road, it is not a good idea to have no breakfast.
If we have no breakfast, we are likely to become tired when our brains and bodies run low on fuel (食物). By mid-morning, a lot of us grab a cup of coffee or eat a sugary candy bar to wake up again. This might work for a few minutes, but by lunch time we are hungry. Eating a good breakfast sets the tone for the rest of the day.
Having no breakfast is a popular way to lose weight, but not a smart one. Many people believe that they will lose weight if they have no meals, but that just isn’t true; the body expects to be refueled a few times a day, starting with a healthy breakfast. Eating breakfast is good for losing weight. In fact, people who eat breakfast are more likely to keep a healthy weight.
A healthy breakfast should have some protein (蛋白质) and some fiber (纤维). Protein can come from low fat meats, eggs, or beans. Fiber can be found in whole grains, vegetables and fruits. A good example of a healthy breakfast might be something simple like a hard boiled egg, an orange, and a bowl of whole grain cereal with low fat milk. Stay away from sugary foods and white bread because they are digested (消化) quickly and will leave you hungry and tired in several hours. Protein and fiber will keep you feeling full until lunch time.
【小题1】The first paragraph mainly tells us that ______.
A.it is necessary to have a good breakfast every day |
B.many adults are too busy to have breakfast every day |
C.many adults go to work without having breakfast |
D.many children go to school without breakfast |
A.we need to have a cup of coffee | B.we don’t have a good breakfast |
C.our brains don’t work any longer | D.we don’t have enough sleep at night |
A.Having a good breakfast can help you to finish your work. |
B.Eating a good breakfast is enough for the whole day. |
C.Breakfast is really the most important meal in a day. |
D.You will be happier if you have a good breakfast. |
A.it is healthy only to have beans and eggs for your breakfast |
B.you mustn’t have meat for your breakfast |
C.you should eat sugary foods if you feel hungry |
D.you should eat something which has protein and fiber for breakfast |

New research suggests that cutting daily sitting time to less than three hours might extend your life by two years.
“Humans were designed to move. But modern lifestyles and office jobs rarely encourage us to walk around,” says Peter Katzmarzyk, an expert at the University of Louisiana.
“Sitting is common in our lives today. We sit while we’re driving, eating and watching TV. And many of us sit for many hours at work.” Katzmarzyk said.
“We can’t throw away physical activity. It’s extremely important. We have 60 years of researchers showing us that.” Katzmarzyk said.
Katzmarzyk and other researchers are trying to discover how sitting all day affext our lifespans(寿命).
“This is a relatively new area of study…Studies that have assessed the relationship between sitting and death or television viewing and death have been very rare in the last four or five years,” said Katzmarzyk.
Katzmarzyk and his colleagues analyzed data from these studies, which involved almost 167,000 adults. Then they turned to a government-run survey of Americans to find out exactly how much time people spend sitting and watching.
Not only did the team find that U.S. citizens could live longer by sitting less, they found that cutting TV time to less than two hours a day could add an extra 1.4 years to their lives.
People who’ve spent half their waking lives sitting down might well ask, “Is it ever too late to make a change?”
“We would say ‘No. It’s never too late.’ Physical activity is good for you at every age.” Katzmarzyk said.
Katzmarzyk says studying this problem has inspired his team to make a few changes in their own lives. They recommend a few simple changes: frequently getting up from your desk, taking walks at lunch time, and instead of e-mailing colleagues, walking over to their offices and talking face-to-face——all activities that can be enjoyable as well as life-extending.
【小题1】Peter Katzmarzyk seems to believe that _____.
A.we should not sit for a long time |
B.most people like to sit most of the time |
C.office jobs encourage us to walk a lot |
D.modern lifestyles are good for our health |
A.taking physical exercise is important |

Will it matter if you don't take your breakfast? Recently a test was given in the United States. Those tested included people of different ages, from 12 to 83. During the experiment, these people were given all kinds of breakfasts, and sometimes they got no breakfast at all. Special tests were set up to see how well their bodies worked when they had eaten a certain kind of breakfast. The results show that if a person eats a proper breakfast, he or she will work with better effect than if he or she has no breakfast. This fact appears to be especially true if a person works with his brains. If a student eats fruit, eggs, bread and milk before going to school, he will learn more quickly and listen with more attention to class.
Opposite to what many people believe, if you don't eat breakfast, you will not lose weight. This is because people become so hungry at noon that they eat too much for lunch, and end up gaining weight instead of losing. You will probably lose more weight if you reduce your other meals.
【小题1】During the test, those who were tested were given ________.
A.no breakfast at all | B.very rich breakfast |
C.little food for breakfast | D.different breakfast or none |
A.he will fall ill |
B.he will fail to listen to his teacher |
C.he will not make progress in his studies |

About a third of all common cancers in the United States, China and Britain could be prevented each year if people ate healthier food, drank less alcohol and exercised more, health experts said on Friday.
Reports from the World Cancer Research Fund (WCRF) suggest that making simple lifestyle changes could prevent some 40 percent of breast cancers alone in Britain and the United States, as well as tens of thousands of stomach cancers.
“Even in 2011, people are dying unnecessarily from cancers that could be prevented through keeping a healthy weight, diet, physical activity and other lifestyle factors,” said a WCRF medical and scientific adviser.
WCRF findings are supported by World Health Organization (WHO) reports, which say regular exercise can prevent many diseases such as cancers and heart diseases.
Cancer is a leading cause of death around the world and its incidence(发病率) is rising. Each year around 12.7 million people discover they have cancer and 7.6 million people die from some form of the disease. There are about 200 known types of cancer.
Rachel Thompson, the WCRF’s head of science, said that while the message was simple — that not smoking, eating good food and being a healthy weight can help ward off many cancers — it was still a difficult one to get across.
The WHO says adults should do at least 150 minutes of exercise a week. This could be done by walking for 30 minutes five times per week or by cycling to work every day.
Peter Baldini, head of the World Lung Foundation, also called on all governments to introduce smoke-free laws and raise the price of cigarettes. Tobacco kills millions of smokers every year, and tobacco-related lung cancers also kill hundreds of thousands of people who don’t smoke but have been exposed to it second-hand.
“There isn’t a magic bullet to cure all forms of cancer, but we have the opportunity and the duty to protect people from developing cancer wherever possible,” Baldini said.
【小题1】Which of the following words can best take the place of the phrase “ward off” in the sixth paragraph?
A.protect | B.prevent | C.develop | D.cure。 |
A.Exercising and eating healthily can help to reduce cancer risk. |
B.Each year about 12.7 million people are diagnosed with cancer around the world. |
C.Every year millions of people die from smoking and lung cancers. |
D.Adults should walk for fifty minutes three times per week. |
A.Simple life changes could stop millions of cancers |
B.Cancer is a leading cause of death |
C.Our bad lifestyle caused many diseases |
D.The incidence of common cancers is rising |
A.advise people to develop healthier lifestyle. |
B.warn people of the danger of cancers |
C.explain why many people die from cancers every year. |
D.introduce the ways to protect people from developing cancers |
A.all the lung cancers are linked to smoking |
B.there is no medicine to cure the cancers but it’s our duty to find one |
C.all governments should take measures to control smokers and protect people’s health |
D.it’s our opportunity and duty to persuade people to give up smoking |

科目:高中英语 来源: 题型:阅读理解
Why are people interested in eating raw foods or whole foods? One reason is that eating these types of food reduces the risk of acid accumulation in your body.
Raw and whole foods are usually digested more efficiently than cooked and refined foods. When we cook foods, we destroy the natural enzymes (酶) that are part of the food in its raw form. These enzymes were intended by nature to help us digest the food. When we consume food without these natural enzymes, our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream. In both instances, the result is obesity. When too many nutrients are absorbed at once, the body grows fat. Improperly digested food moves slowly through the digestive tract, where it becomes increasingly acidic. To protect its vital organs from this acidic waste, the body changes the acid into fat and stores it safely away from the organs.
Processed foods contain chemical elements, which might confuse the appetite mechanism that tells us when we’ve had enough to eat; as a result, people often overeat. Processed foods also upset the digestive cycle. The body will either identify these foods as allergens and then store them safely away from the organs as fat, or the remains of undigested food will become acidic and enter the bloodstream as acid waste, which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body’s cells. The body’s metabolism (新陈代谢)becomes inactive, and the result is weight gain and obesity.
The accumulation of acid in the digestive tract makes digestion increasingly inefficient. When that happens, even healthy foods can become acidic and the food allergies will become more common.
To stop this vicious(恶性的)circle in its tracks, people need to consume food and supplements that will neutralize (使…中和) the acid already accumulated in body. Eating the right types of raw and whole foods can help. It’s also important to restore your enzyme balance. You need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production. If you truly want to change and help your body heal itself, you need to take an active approach.
【小题1】What is the main purpose of this passage?
A.To advocate eating more raw and whole foods. |
B.To tell the differences between raw and processed foods. |
C.To inform people of the harm of processed foods. |
D.To warn people of the problem of obesity. |

B.foods with natural enzymes help people keep fit |
C.we’d better be cautious about raw and whole foods |
D.giving up cooked and refined foods is a new lifestyle |
A.destroy body’s cells | B.are difficult to digest |
C.may lead to obesity | D.stop body’s metabolism |
A.Active approaches to avoid acid. |

D.Suitable types of raw and whole foods. |
A.Processed foods are good for our appetite mechanism. |
B.Eating the right types of raw and whole foods does good to our body. |
