Below are some smart ways to stay healthy suggested by some American experts.
Drink More Coffee
When was the last time you heard a doctor use the word miracle? Well, wake up and smell the coffee: “It’s amazing,” says liver specialist Sanjiv Chopra, MD, professor of medicine at Harvard Medical School. “Coffee is truly a lifesaving miracle drug.”
Though he says it’s still a “scientific mystery” how a simple cup of coffee works its wonders in the body, large epidemiological studies have repeatedly proved its astonishing benefits.
“Drink it black, or at most put a little skim milk in it” to minimize calories, Dr. Chopra recommends. He drinks at least four cups a day himself, though most people should limit themselves to two. And no, he jokes, “I’m not sponsored by Starbucks.”
Take a Walk for Your Memory
Aerobic (有氧運動的) exercise is good for your body, great for your mind, according to the latest research from brain-fitness pioneer Arthur Kramer. Every year, an area called the hippocampus, which is key to memory, shrinks by about 1 to 2 percent, increasing the risk of dementia (腦衰) as the years roll by. However, Kramer’s new investigations reveal that the hippocampi of adults who walked briskly for about 45 minutes three times a week grew by about 2 percent over the course of a year, preventing age-related shrinking.
It’s never too late to start exercising, Kramer says; volunteers in his research were between 55 and 80 years old and hadn’t exercised at all. And it doesn’t need to be backbreaking. “Anything that raises your heart rate seems to work,” he says. “Walking is fine. Just find something you like and do it.”
Early to Bed, Early to Eat
“Being a night owl might increase your waistline,” says sleep expert Michael Breus, PhD. People who stay up late and sleep late tend to eat more fast food and consume more of their calories after 8 p.m. than do normal sleepers.
“One of the easiest things that anyone on a diet can do to improve her results is go to bed and wake up at the same times every day,” Breus says. “This way, your body knows when to sleep and is much more efficient. Organize your eating, too, by trying to eat meals at the same times every day. Avoid eating after 8 p.m., and don’t miss morning meals by sleeping in.”
Use the 20-Second Rule
What’s the difference between having a goal and actually accomplishing it? Just 20 seconds, says positive-psychology specialist Shawn Achor. Researchers have learned that if we can cut 20 seconds off the startup time required for a task, we’re much more likely to follow through. So, for example, if you want to work out in the morning, place your shoes and exercise clothes next to your bed the night before. If you want to praise people more, put thank-you notes and a pen on your desk.
Imagine the Worst to Feel Better
Don’t count your blessings; subtract (扣除) them. “Consciously spend a few minutes imagining what your life would be like without the good things,” says Timothy Wilson, a psychologist at the University of Virginia. You’ll experience stronger feelings of love, gratitude, and happiness when you think about what life would be like without the people and things you love. “And they’ll seem surprising and special again,” he adds.
小題1: According to Sanjiv Chopra, most people should not drink more than ______ cups of coffee a day.
A．twoB．threeC．fourD．six
小題2:Which of the following may help people on a diet to improve their results?
A．Raising their heart rate.B．Taking a walk for their memory.

Telecommuting(遠程辦公) will have major effects on the worlds of work and family life. However, its biggest effect will be in the area of individual freedom, responsibility and time management.
Work and workplaces will change greatly. Offices may become smaller, as fewer desks are needed. There will be greater need for high-speed Internet connections to link the office and the home, and even homes to other homes, as other employees also begin working at home. Hours spent in traffic jams, and fights for parking should diminish, as workers travel less.
Family life will also change. Both husbands and wives will be able to arrange their work around family commitments such as taking children to school, cooking, spare time activities, and so on. However, households(家人) will also have to set aside areas for work-particularly if more than one person is telecommuting.
However, although the ideas of more time at home and less time traveling are attractive, there are some drawbacks to telecommuting. People may feel that they cannot escape from work, work longer hours, or become less social. The quality of work may suffer because of fewer face-to-face interactions with other employees, and there may be delays if other workers are not immediately available. Telecommuters may also feel isolated. A major change will be in the way people think about work as a place or an institution. Instead, they will focus on the task or the product. Workers may feel less loyal to a company.
In conclusion, the effects are difficult to predict because they depend on the extent to which telecommuting becomes popular. At the same time, however, telecommuting could be the start of a major societal shift, possibly as big as the Industrial Revolution which created our present ideas of work.
64. This passage was mainly written to tell us _____.
A. about the advantages of telecommuting               
B. how telecommuting will change the world
C. that telecommuting will affect family life            D. how to telecommute in the future
65. What is Paragraph 4 mainly about?
A. The disadvantages of telecommuting.                  B. Setting aside areas for work.
C. The future of telecommuting.                             D. The employees’ focus on work.
66. With telecommuting in the future, which of the following will be reduced?
A. Working hours and family time.                         B. Face-to-face communication.
C. Spare time and individual freedom.                            D. Spending time with friends.
67. What can we infer from the passage?
A. Telecommuting will change the world completely.
B. There will be no traffic jams because of telecommuting.
C. Work efficiency will increase through telecommuting.
D. Telecommuting workers will likely change their jobs.

Eight in 10 Americans eat fast food at least once a month and half eat it every week according, to a Gallup Poll. Yet most people who eat fast food know it’s bad for them. So why do they keep eating it?
The answer is simple: the benefits of eating fast food outweigh the long-term implications for most people. However, once you read these reasons why all those trips to the drive through may be slowly killing you, you may just want to stop eating fast food after all.
1. Fast food makes you fat.
A 15-year study of over 3,000 people found that eating fast food is linked to weight gain and insulin resistance. In others words, fast food makes you fat and increases your risk of type 2 diabetes. You probably know this already. But here’s something you may not know.
2. Fast food is addictive.
The more you eat fast food, the more you crave it. One study found that fast food is “a potentially addictive substance that is most likely to create dependence in vulnerable populations.” If you eat fast food once a week or more, you may be addicted to it.
3. Fast food is affecting your kids.
According to the CDC, childhood obesity has more than doubled in children and tripled in adolescents in the past 30 years. Kids have an amazing ability to recall ads they’ve seen. Fast food marketers know this, and design ads accordingly. Research shows strong associations between increases in advertising for non-nutritious foods and rates of childhood obesity.
4. Fast food “burgers” don’t have much burger in them.
One study found that most fast food burgers are composed of about 50 percent water and the actual meat content is only 2.1 to 14.8 percent. So what makes up the rest of it, you ask? Chemical fillers and preservatives, mostly. That’s why we see read horror stories about burgers that don’t go bad.
5. Even “healthy” fast food isn’t that healthy.
Fast food restaurants are catering to consumer demands to produce healthier options. The problem is, their definition of “healthy” is quite lax. One of the healthiest dishes at Burger King, the Garden Fresh Salad Chicken Caesar with TENDERGRILL Chicken and dressing, still has almost 500 calories and 28 grams of fat, and nearly a day’s worth of sodium.
6. Fast food is inhumane to animals.
Okay, this one may not be a reason why fast is killing you, but it’s still a compelling reason to stop eating fast food. 9 billion animals were slaughtered in the US alone in 2012 and much of that meat is for your fast food burgers and chicken sandwiches. Large factory farms resemble more of a “business” than a “farm.” Animals suffer in crowded spaces where they rarely have access to the outdoors or sunlight. They are pumped full of antibiotics to combat disease, which runs rampant in these conditions. Livestock is one of the biggest sources of pollution and environmental negligence, according to the UN.
7. Fast food sodas are loaded with sugar.
High fructose corn syrup (HFCS) is the cheap sweetener most fast food restaurants use in their sodas, desserts, and many other products. Princeton University researchers linked HFCS consumption to obesity in an animal study. Rats given HFCS gained more weight and body fat than those given table sugar.
小題1:How many factors are mentioned which can account for the reason why fast food is slowly killing you?
A．Seven.B．Three.C．Four.D．Five.
小題2:According to the text, we know that_____.
A．many people keep eating fast food because they know nothing about the harm which fast food will bring them
B．fast food plays a key role in children’s growth
C．eating fast food is connected to weight gain and insulin resistance.
D．many fast food restaurants are can offer a good and healthy meal to consumer
小題3:What is the purpose of the passage?
A．To help us make right decisionsB．To advise us to stop eating fast food
C．To tell us how to keep fitD．To encourage us to be humane to animals

Climate change could affect food supplies, water resources, human health and homes.
If greenhouse gas emissions keep increasing at the current rate, global temperature is expected to rise between 2°C and 6°C by 2100. This doesn’t sound much, but a 5°C change is the difference between the current warm period and an ice age. 
Global warming leads to other changes in the climate: melting ice, more evaporation(蒸發(fā)), changes in geographical patterns of rainfall, heavier downpours separated by longer dry spells, more frequent heat waves, more intense hurricanes, and sea level rise. 
These changes could affect crop growth as drought, increased evaporation and shrinking glaciers（冰川）disrupt water supply. Some crops could suffer heat stress. While there may be benefits in some regions, overall climate change is likely to have a negative impact on global food supplies. The impacts of climate change on agriculture will vary widely around the world. A global temperature rise of 1–2 °C is expected to increase food production in some regions, particularly mid-latitude areas. But in tropical regions even a small amount of warming could reduce crop yields. A temperature rise of 3 °C or more could threaten global food resources, as all regions are likely to experience negative impacts overall.
Freshwater resources could also diminish, especially in tropical regions, as rain patterns change and evaporation speeds up. Some communities could lose essential melt water as glaciers disappear, while more intense rainfall and hurricanes could cause more flooding, leading to water pollution and bacterial diseases such as cholera（霍亂）becoming more widespread. 
Climate change could lead to a variety of health impacts – both positive and negative. On the negative side, scientists anticipate more cases of malnutrition, heatstroke and waterborne diseases such as cholera. Although some populations will benefit from a reduced risk of cold-related illnesses such as hypothermia, overall a warming world is likely to have negative effects on human health.
Scientists also expect damage to homes and buildings from more intense hurricanes, heavier rainfall and rising sea levels. Climate change is likely to affect infrastructure by increasing the risk of both coastal and inland flooding around the world, owing to a combination of heavier rainfall, rising sea levels and increased storm damage. Homes and buildings could also be affected by the thawing of frozen ground and greater risk of forest fires.
The consequences of climate change will have an impact on people around the world.
小題1:With global temperature increased by 1–2 °C, _______.
A．crops yields could be increased in tropical regions
B．food production could rise throughout the world
C．chances are that food resources would be threatened overall
D．mid-latitude areas are likely to experience positive impacts
小題2:The underlined word “hypothermia” in Paragraph 6 possibly means a serious medical condition caused by_______.
A．lower temperature than normal
B．higher temperature than normal
C．more cases of malnutrition
D．cases of waterborne diseases
小題3:According to the passage, climate change has both positive and negative effects on ______.
A．food supplies and buildings
B．freshwater resources and homes
C．human health and food supplies
D．human health and homes
小題4:The passage is mainly meant to tell us _______.
A．how global warming leads to changes in the climate
B．how climate change affects people worldwide
C．why climate change affects our crop growth
D．why climate change contributes to all bad results

A new study links heavy air pollution from coal burning to shorter lives in northern China. Researchers estimate that the half-billion people alive there in the 1990s will live an average of 5 years less than their southern counterparts because they breathed dirtier air.
China itself made the comparison possible: for decades, a now-discontinued government policy provided free coal for heating, but only in the colder north. Researchers found significant differences in both particulate pollution of the air and life expectancy in the two regions.
While previous studies have found that pollution affects human health, "the deeper and ultimately more important question is the impact on life expectancy," said one of the researchers, Michael Greenstone, a professor of environmental economics at Massachusetts Institute of 一Technology. "This study provides a unique setting to answer the life expectancy question because the(heating) policy dramatically changes pollution concentrations（含量），，，Greenstone said in an email. "Further, due to the low rates of migration in China in this period, we can know people's exposure over long time periods," he said.
The policy gave free coal for fuel boilers to heat homes and offices to cities north of the Huai Riv饑which divides China into north and south. It was in effect for much of the 1950-198,0 period of central planning, and, though discontinued after 1980, it has left a legacy（遺留） in the north of heavy coal burning, which releases particulate pollutants into the air that can harm human health. Researchers found no other government policies that treated China's north differently from the south.
The researchers collected data for 90 cities, from 1981 to 2000, on the annual daily average concentration of total suspended（懸浮的）particulates. In China, those are considered to be particulates that are 100 micrometers or less in diameter, sent out from sources including power stations, construction sites and vehicles. Among them, PM2.5 is of especially great health concern because it can go deep into the lungs.
The researchers estimated the impact on life expectancies using death data from 1991-2000． They found that in the north, the concentration of particulates was 184 micrograms per cubic meter一or 55 percent higher than in the south, and life expectancies were 5.5 years lower on average across all age ranges.
小題1:The main idea of this passage is that＿·
A．research in China finds air pollution shortened life expectancy
B．the government provided free coal for heating in North China
C．coal burning causes bad air quality across China
D．a new study finds different particulates in South China
小題2:According to Greenstone,＿greatly contributed to the high pollution concentrations in North China.
A．power stationsB．construction sites
C．the free heating policyD．gases from vehicles
小題3:It is implied in the passage that＿·
A．coal is no longer used for heating in North China
B．air quality was comparatively better in South China
C．southerners burned coals for heating in the 1980s
D．people preferred to live in South China after 1980
小題4:The underlined word "particulates" most probably means＿．
A．dirty cloudsB．particular smoke
C．harmful dustD．dangerous bacteria

Eat nuts, live longer.  Researchers have found that those who eat a handful of peanuts every day significantly decrease their risk of dying from all causes compared to those who do not eat nuts. A new study concludes that all types of nuts seem to be protective.
Researcher Ying Bao is with the Department of Medicine at Brigham and Women’s Hospital and Harvard University Medical School in Boston, Massachusetts. She and her colleagues looked at the impact of nut consumption by analyzing two huge studies that began in 1980 - the Nurses’ Health Study, which tracks the well-being of more than 76,000 women, and 42,000 men enrolled in the Health Professionals Follow-up Study.
Among the questions asked at the beginning of the studies was, 'how frequently do you eat nuts?'  The information was updated every two to four years. Bao says the participants were followed for three decades.
“What we observed is that people who eat more nuts are less likely to die over the next 30 years," said Bao. "So, for example, if a person eat(s) nuts once per day, that person has a 20 percent lower risk of dying.”
Bao says eating a handful of nuts five or more times per week was associated with a 29 percent reduced risk of dying from heart disease and an 11 percent lower risk of cancer death.  A serving size is 28 grams.
Nuts contain nutrients, including high quality proteins, vitamins and minerals, all of which have anti-cancer effects and may help protect the heart.
Bao says researchers are planning studies to find out how nuts are beneficial to human health.
The study on the health benefits of nuts was funded by the International Tree Nut Council Research and Education Foundation.
小題1:People who often eat nuts ________.
A．are more likely to live longer than people who often eat fruits
B．don’t need to go to hospital
C．may live longer than people who don’t eat nuts
D．don’t have to do sports
小題2:The underlined word “well-being” in Paragraph 2 shares the same meaning as “________”.
A．illnessB．healthC．dietD．habit
小題3:About Bao’s research, which statement is true?
A．She has done the research by herself.
B．Her research was based on two studies.
C．Her research lasted about three years.
D．People should eat all kinds of nuts every day.
小題4:Eating nuts may help us stay away from ________.
A．cancerB．feverC．fluD．headache

While there has been public debate about whether running is good for your health for a long time, experts agree that running has more benefits than the costs. Some people are concerned that the pressure on your knees and ankles can be detrimental. While this can be true, there are many things that you can do to reduce your risk of injury.
You should always go to a doctor for advice before you begin any type of exercise program. Then, a good pair of running shoes can be helpful as your feet hit the ground. They will help protect your ankles by providing stability to your feet. So it is good idea to visit a specialty(專業(yè)) running shoe store. The staff there can suggest shoes which are ideal for your running style.

Different exercise types have different purposes and different benefits. One type of exercise may not accomplish all goals of being physically fit: a healthy heart, strong muscles and bones, and safety from injury. As a result, it is important to do enough types of exercise to have all the physical benefits. Here is a quick check sheet.
Aerobic Exercise: To have a strong and healthy heart, you need to do aerobic exercise. This means that you need to exercise yourself enough so that your heart rate, while exercising, is 65 percent to 85 percent of your maximum heart rate. If you don’t get your heart rate up within this level—you just aren’t working hard enough. Whatever you do, your heart rate needs to be 65 percent to 85 percent of your MHR for 20 to 30 minutes, at least 3 times a week. Typical types include:
* Running
* Walking (at least 4 to 4.5 mph)
* Swimming
* Biking
* Elliptical Training (橢圓運動)
* Yoga
Strength Training: To keep your muscles and bones strong, you need to do strength training. This comes in a variety of forms. Whatever you do, however, you need to train your muscles enough so that they are really tired by the end of each session. To see real benefits, make sure you are strength training 2 to 3 times a week for about 30 to 40 minutes. Typical types of strength training include:
* Weight Training
* Yoga
* Resistance Training
* Plyometrics（肌肉增強訓練）
Flexibility Training: To keep your body flexible, reducing risk of injuries and pain in your joints and muscles, you need to do flexibility training. You should always aim to stretch every muscle after any exercise routine. Typical types of flexibility training include:
* Stretching
* Yoga
* Pilates（普拉提課程）
So next time you think that yoga 5 times a week will be enough, think about what it is really doing. Is it getting your heart rate up? Are you making up your strength? Are you keeping your muscles flexible?
小題1:If your purpose is to _______, you can choose swimming as your exercise form.
A．build a strong and healthy heart
B．keep muscles and bones strong
C．keep body flexible
D．reduce risk of injuries and pain in joints and muscles
小題2:After reading this passage, we know that ________.
A．Yoga is really better for people than running
B．The more exercise you do, the better
C．Flexibility training helps you build up your muscles
D．The three kinds of training have links with one another
小題3:Which of the following is closest in meaning to “session” in Paragraph 3?
A．meetingB．gatheringC．periodD．term
小題4:The paragraph following this article may discuss_______.
A．how to find a good workout dealing with two or three of these goals
B．how to choose an exercise type
C．how to build up our strength
D．how to be more flexible
