Most people are worried about the health of economy. But does the economy also affect your body health?
It does, but not always the ways you might expect. The data(数据) on how an economic downturn influences an individual’s health is mixed.
It’s clear that a long-term economic rise leads to improvements in a population’s overall health, in developing and developed societies alike.
But whether the short-term economic fall will damage your own health depends on your health habits when times are good. And economic studies suggest that people usually do not take care of themselves in good times—drinking too much, dining on fattier restaurant meals and skipping exercises.
“The value of time is higher during good economic times,” said Grant Miller, a professor of medicine at Stanford. “so people work more and do less of the things that are good for them, like cooking at home and exercising. ”
Similar patterns have been seen in some developing nations. Dr. Miller, who is studying the effects of fluctuating coffee prices on health in Colombia where coffee plays an important role in economy development, says that although falling prices are bad for the economy, they appear to improve the population’s overall health. When prices are low, laborers have time to enjoy their own life such as doing housework, exercising and taking care of their children, etc.
“When coffee prices suddenly rise, people work harder on their coffee fields and spend less time doing things around the home, including things that are good for their children,” he said.
Christopher J. Rohm, professor of economics at University of North Carolina. US shares similar ideas.

People who are worried about bad breath often reach for a toothbrush or a gun. But in the future, personal breath monitoring may include far more than fresh breath.
In face, breath is so rich in chemical compounds that fully understanding it has proved challenging. Each breath contains gases like carbon dioxide, the volatile(挥发性的)remains of recent snacks, medicines and even compounds taken in from things like carpeting or various kinds of air pollution. But breath detectors(检测器) can sort out these substances with increasing sensitivity(敏感性)。
Scientists are building electronic sniffers that examine the exhaled(呼气)air for signs of cancer, asthma(哮喘), and other diseases.
“There are clear signatures in the breath for liver(肝)disease, kidney(肾)disease and heart disease. Breath is a rich mixture that can reflect out state of health and disease.” said Dr. Raed Dweik, director of the Cleveland Clinic, adding “Breath analysis is the future of medical testing.”
He and his partners are testing a desktop system called BreathLink for use in rapid identification of diseases. The system is designed to work wherever there is an Internet connection. To use BreathLink, a person breathes into a long tube, and a breath sample is collected and analyzed within the system. Then it can detail chemical concentrations(浓度)of the breath in graphics. Dr. Raed Dweik said, “If you examine patients of asthma, you will find they have higher levels of nitric oxide(一氧化碳) in their exhaled air. It reflects their abnormal symptoms in the lungs.” His tests have reached 85 percent accuracy(精确度)so far in spotting people with some illness.
But some trained dogs, he pointed out, can sniff out cancer with 99 percent accuracy—although without the ability to identify particular compounds the way some detectors can.
“We are getting better and better,” he said. “But whether we will ever approach the accuracy of the dog—we don’t know.”
1.What is the breath detector used for?
A. To find what kind of disease a person has.
B. To identify substances from people’s breath.
C. To help a patient recover from disease.
D. To smell how bad the breath is.
2.In the fifth paragraph, what Dr. Raed Dwik said is meant to______.
A. show how he and his partners treated patients
B. tell why a person has asthma
C. show how sensitive the device is
D. show how to diagnose a patient of asthma
3.It can be inferred that_______
A. brushing teeth can improve one’s bad breath
B. there are leftovers like snacks and medicines in one’s breath
C. one can know exactly about his physical state through the breath
D. breath analysis can be helpful in medical diagnosis
4.What’s the author’s attitude towards the future of breath detectors?
A. Indifferent B. Positive
C. Doubtful. D. Critical.

Some people worry about being the target of laughter. These people are frightened. They suffer from an emotional disorder called gelotophobia. That long name comes from the Greek language. The word Gelos means laugh, while phobos means fear.
Victor Rubio is an expert on human behavior at the Autonomous University of Madrid. He says people laugh at others for many different reasons. He says being laughed at causes a fear response in the victim. That fear leads the victim to avoid social situations. Sadly, gelotophobia limits the way they lead their lives.
Victor Rubio was among researchers in a huge international study about laughter. The researchers wanted to understand the difference between normal shyness and true gelotophobia. Another goal was to measure the fear of being laughed at within different cultures.
A team from the University of Zurich led ninety-three researchers from many countries in search of answers.
The researchers surveyed more than twenty-two thousand people. They used questions provided in forty-two languages. Their findings were reported in the scientific publication Humor.
Some of the people questioned said they felt unsure of themselves in social situations. But they hid their feelings. Others said they avoided social situations where they had been laughed at before. People also admitted to differing levels of fear that they themselves were the targets of other people’s laughter. The researchers measured and compared all these reactions.
Fear of being laughed at, being made fun of, is a common emotion. But the researchers learned that these feelings differed from nation to nation.
For example, the study found that people in Turkmenistan and Cambodia are likely to hide insecure (不安) feelings when they are around others’ laughter. But people in Iraq, Egypt and Jordan who feel they have been victims before may avoid such situations.
People in Finland were the least likely to believe that people laughing in their presence were making fun of them. Only eight and a half percent of Finns said they would – compared to eighty percent of those questioned in Thailand.
1.The passage is mainly about______________.
A. a common emotion B. laughter shyness D. gelotophobia
2.In which country are people most likely to avoid social situations where they have been laughed at before?
A. Turkmenistan B. Iraq Finland D. Thailand
3.According to the text the following is true EXCEPT that ________.
A. people suffer from gelotophobia because they are shy
B. not all the people questioned hid their feelings in social situations
perhaps Humor is a magazine
D. people in Finland are the least likely to suffer from gelotophobia
4.A person who suffers from gelotophobia will probably ______.
A. be active in social activities B. be easily laughed at
like to laugh at others D. like to stay alone

Long nights of winter can leave even the most positive people feeling cranky(古怪的).But for about 5% of Americans, it’s more serious: seasonal affective disorder (SAD) is a type of depression that most occurs in the winter. Symptoms include loss of energy, eating more and difficulty in concentrating.
The cause of SAD is unknown, but darker days probably play a role. Reduced levels of natural sunlight can disrupt your body’s internal clock, which can lead to depression. It also causes a drop in serotonin (血清素),a feel-good brain chemical. Severe cases may need antidepressant treatment. You can’t prevent the disorder from developing, but you can ease the symptoms.
Consider light therapy
Exposure to bright light that mimics(模仿)natural light is thought to affect mood-related brain chemicals and ease symptoms. It involves sitting in front of a special light box or wearing a cap-like lighted visor (盔甲),for about 30 minutes a day. Another therapy uses a “dawn simulator” that is turned on early in the morning and gradually increases in brightness, allowing your body to wake up naturally. Light therapy can have minor side effects, such as eye strain and headaches, and it isn’t recommended for people with skin sensitivity.
Go outside
Yes, even if it’s cold and cloudy. Natural light is still good for you, and it can relieve your symptoms, especially if you head outdoors within two hours of waking up. At home, open the blinds and drapes to let in the light.
Eat right and exercise
Two health basics can help here, too. A well-balanced diet can improve energy levels, and regular physical activity works to boost your mood and ease stress and anxiety which can aggravate SAD symptoms.
Spend time with friends
Make an effort to see people you enjoy, even when you’re down. Staying connected to your social circle and participating in your regular activities can offer great support during the winter months.
1.Which of the following about SAD is NOT true?
A. It most occurs in the winter.
B. It may result in the absence of concentration.
C. It results from too much exposure to the sun.
D. Causes remain to be discovered.
2.Light therapy .
A. is of no use unless being exposed to the sun for about 30 minutes a day
B. is a good way to anyone
C. can prevent seasonal affective disorder from developing
D. doesn’t suit those with skin sensitivity
3.What does the underlined word “aggravate” mean in the passage?
A. To make something worse. B. To get rid of something.
C. To make anything better. D. To get anything changed.
4.Which column could the passage come from?
A. Education. B. Finance.
C. Travel. D. Science.
高三英语阅读理解中等难度题查看答案及解析
Governments all over the world make public reports about the condition of their economies. Most countries, including the United States, have used a measure called the gross national product (国民生产总值)or GNP. It includes all goods and services produced by citizens of the country anywhere in the world.
Recently the American Commerce Department has started using a new method to measure production. It is known as the gross domestic product(国内生产总值)or GDP. It counts only goods and services that have been produced within the nation’s borders. Money earned by foreign companies operating in the United States is included in the GDP, but money earned by American companies operating in other countries is not.
Economic experts generally approve of the change. They say that the gross domestic product provides a truer measure of the economy. They also note that most other industrial countries use this method. Therefore it will be easier to study the economies of different countries. Some officials also hope the new system will help them make better economic policy decisions. It will provide them with a clearer understanding of economic activity in the U.S. . The new measure is less likely to be affected by sudden changes in foreign oil prices or in the value of the American dollar in other countries.
Economic experts believe that the change from GNP to GDP will immediately reduce the value of American production by at least 40,000 million dollars a year. But that is really a very small change in the American economy – less than 1% . The Commerce Department reports the unofficial gross domestic product once every three months. The government also continues to report GNP as it has four times a year since 1941.
1.To report the American GNP, the government should not consider goods and services produced _______.
A. by American companies at home
B. by American companies in China
C. by American companies in Singapore
D. by Japanese companies in the United States
2.To report the American GDP, the Commerce Department should count money earned ________.
A. by both American and foreign companies in America
B. by American companies within its own borders
C. by foreign companies in the United States
D. by American companies in its foreign markets
3.GDP is considered better than GNP by some economists because ________.
A. it is something new
B. it is used by most countries
C. it is easier to calculate
D. it is less likely to be affected by the foreign market
4.What will happen to the value of American economy if GDP is used to replace GNP?
A. It will be seriously affected. B. It will not be affected.
C. It will come down a little. D. It will slightly go up.
5.How often are the reports of GDP issued by the American Commerce Department?
A. once every four months B. once every three months
C. once every six months D. once a year
高三英语阅读理解中等难度题查看答案及解析
Most people are aware that outdoor air pollution can damage their health,but many do not know that indoor air pollution can also have significant health effects.Environmental Protection Agency studies indicate that indoor levels of pollutants may be 3~5 times,and occasionally more than 100 times,higher than outdoor levels.These levels of indoor air pollutants may be of particular concern because most people spend about 90% of their time indoors.
There are many sources of indoor air pollution in any home.These include sources such as oil,gas,coal,wood,and tobacco products,building materials,wet or damp carpet,and furniture made of certain pressed wood products,products for household cleaning and maintenance,personal care,or hobbies,central heating and cooling systems.
Immediate effects may show up after a single exposure (暴露) or repeated exposures.These include irritation of the eyes,nose,and throat,headaches,dizziness.Such immediate effects are usually shortterm and treatable.Sometimes the treatment is simply removing the person’s exposure to the source of the pollution,if it can be identified.
The likelihood of immediate reactions to indoor air pollutants depends on several factors.Age and preexisting medical conditions are two important influences.In other cases,whether a person reacts to a pollutant depends on individual sensitivity,which varies tremendously from person to person.Some people can become sensitized to biological pollutants after repeated exposures,and it appears that some people can become sensitized to chemical pollutants as well.
Certain immediate effects are similar to those from colds or other viral (病毒性的) diseases,so it is often difficult to determine if the symptoms are a result of exposure to indoor air pollution.While pollutants commonly found in indoor air are responsible for many harmful effects,there is considerable uncertainty about what concentrations or periods of exposure are necessary to produce specific health problems.People also react very differently to exposure to indoor air pollutants.Therefore,further research is needed to better understand the effects of indoor air pollution and to find efficient ways to protect our health.
1.According to the first paragraph,which of the following is NOT true?
A.People often fail to notice indoor air pollution.
B.Indoor air pollution sometimes is more dangerous than outdoor air pollution.
C.Outdoor air pollution may not be so serious as indoor air pollution.
D.It is obvious that people have been paying more attention to indoor air pollution.
2.According to the author,which may NOT be the source of indoor air pollution?
A.Building materials. B.Wet carpet.
C.Cooling system. D.Refrigerators.
3. What does the underlined word “irritation” in the third paragraph probably mean?
A.Bad intention. B.Much sensitivity.
C.Injury. D.Carelessness.
4. Which of the following might be the best title for the passage?
A.Reactions of Pollution B.Danger from Home
C.Pollution Resources D.Different Pollutions
