Older adults with a better sense of smell may live longer than those who have a poor sense of smell, a new study suggests. The study was a project of researchers in the United States that was continuing for over 13 years. They asked nearly 2300 men and women to recognize 12 common smells. All the subjects were from 71 to 82 years of age. The researchers gave the adults marks, from 0 to 12, based on how many smells they recognize correctly.
During the years of follow-up research, over 1200 of the adults died. When the study was started, none of the adults were weak. They could walk about half a kilometre, climb 10 steps and independently complete daily activities. In the latest findings, the researchers noted those with a weak nose were 30% more likely to die than people with a good sense of smell. The findings were reported last month in the scientific publication Annals of Internal Medicine.
Honglei Chen, a doctor with Michigan State University in East Lansing, Michigan, was the lead author of the report on the study. He said the connection between a poor sense of smell and an increased risk of dying was limited to adults who first reported good or excellent health. This suggests that a poor sense of smell is an early and sensitive sign of worsening health before it is recognizable in medical tests. With a poor sense of smell, people are more likely to die of brain and heart diseases, but not of cancer or breathing problems.
The results also suggest that a poor sense of smell may be an early warning of poor health in older age that goes beyond dementia (痴呆) or other neurodegenerative (神经变性的) diseases. These often signal the beginning of the weakening of the mind or body.

Dog owners walked about 23minues longer each day than non-dog owners In a new study, dog owners took 2,760 additional seps—compared to people who didn’t have a dog at home. Bu here’s the real good news: That extra exercise was done at a moderate(适度的)pace, which means it could help adults meet their recommended weekly totals for physical activity.
The research, published in BMC Public Health, focused on adults 65 and older, who tend to be less active than younger people. The study included 43 dog owners and 43 non-dog owners, all of whom were monitored continuously for three week-long periods. When they compared the two groups, the researchers found that dog ownership was associated with a large, potentially health-improving effect.
Dog owners walked about 23 minutes longer each day than non-dog owners, 119 minutes versus 96 minutes on average. They also took an additional 2,760 steps, and had eight fewer continuous periods of sitting down. Most of that extra walking was done at moderate pace, defined as 100 or more steps a minute. Dog owners walked at this pace for 32 minutes a day, versus just 11 minutes a day for non-dog owners.
The World Health Organization(WHO)recommends that adults get at least 150 minutes of physical activity a week. This increased walking time alone could just about satisfy that requirement, say the researchers—so it makes total sense that 87 percent of dog owners in the study met these guidelines, versus just 47 percent of non-dog owners.
Co-author Nancy Gee says that pet ownership may help older adults get more activity or maintain their current activity level for a longer period of time. “This could improve their chances of a better quality of life, improved or maintained cognition(认知), and perhaps, even overall longevity(寿命),”she said.
Here at Health, we’ ll add that caring for pets has been shown to have plenty of other physical and mental health benefits, as well. As animal lovers ourselves, we’ re happy to add one more to the list.
1.What can we learn about the research?
A.It was targeted on old people.
B.It was sponsored by the WHO.
C.It had an undesirable effect on dog owners.
D.It took the mental health of dog owners into consideration.
2.What does the author intend to do in Paragraph 3?
A.To present the results of the research.
B.To show the guidelines of the research.
C.To describe the process of doing the research.
D.To explain the reasons for conducting the research.
3.What does Nancy Gee think of owning a dog?
A.It is too expensive.
B.It is time-consuming.
C.It enables older adults to live a healthy life.
D.It helps young adults to keep a healthy routine.
4.What is the best title for the text?
A.Non-pet owners enjoy more pleasure
B.Animal lovers are more generous
C.Young people walk less today
D.Dog owners walk way more

When you think of the supper-healthy people, you’ll find they all have some good habits. Here are some of their habits.
Have breakfast
1.. Studies show that adults who have a healthy breakfast do better at work, and kids who eat a morning meal score higher on tests. Just don’t skip it.
2.
People need to drink enough water every day. But sugary drinks are linked to obesity and diabetes (糖尿病). So plain water is the best choice. If you aren’t a fan of plain water, add flavor with slices of orange, lemon, lime, watermelon, or cucumber.
Do some exercise
Don’t just have another cup of coffee—get up and move. Do some exercise. It’s great for your body and mind. Just 30 minutes of walking five times a week can be helpful. 3..
Learn something new
New skills help keep your brain healthy. 4.. Better yet, master a new language. The mental work can slow the signs of aging and may even delay the effects of Alzheimer’s disease.
Keep your balance
5.. If you’re older, it will keep you active longer and lower the chances of breaking a bone when you fall over. No matter your age, good balance means better muscle tone, a healthier heart, and greater confidence. Yoga and Tai chi are great ways to work on it, but just about anything that keeps you moving, can help.
A.Drink plenty of water
B.It’s important to have breakfast
C.No matter what you do, it benefits you
D.Drink sugary water instead of soft drink
E.Sign up for a dance class or a creative writing class
F.If you’re young, good balance will help you avoid injuries
G.If you have no time to do exercise that long, short-time exercise helps, too

Some of the recent scientific studies have found that people who receive higher education live longer than those who do not. According to a new study, reading books extends lifespan(寿命) by up to two years, and the more often you read, the better.
Back in 1975, economists concluded that longer lifespan is linked to the wealth of a person, and that wealth itself increases longevity. It seemed self-evident: everything people need to be healthy from food to medical care costs money. But soon it was realized that the data didn’t always fit that theory. Economic success didn’t always mean longer lives.In the 1980s, researchers found gaining higher education is connected with a greater increase in lifespan than gains in wealth.
One fact is of teachers and college professors: they live longer than the rest of the population. The reason is that they engage in research most of their lives for teaching or publishing, which increases their lifespan and most importantly also retards their aging process.
Let’s look at what benefits educated people. Educated people get routinely involved in social networks, they get access to information because of their ability to understand information. They can easily navigate (导航) the health care system; they have more social support.
Reading helps us understand how other people think and feel. Reading improves our emotional intelligence. This understanding can improve the quality of a person’s life as it would allow the person to act with better judgment and have more insight into the feelings and thought patterns of others. Research has shown that reading changes certain areas of the brain and causes certain other parts to be active. This effect can also be observed in adults who learn to read much later in life. Learning has no age bar. Each and every human is born with the right to be educated. So, don’t hold back your urge to learn. The goal of education is to improve intelligence as well as the lifespan.
1.What did researchers find in the 1980s?
A.Education does affect peoples lifespan.
B.Health has nothing to do with wealth.
C.Economic success always belongs to professors.
D.Children from poor families can rarely gain higher education.
2.What does the underlined word “retards” in Paragraph 3 mean?
A.speeds up B.slows down
C.turns back D.contributes to
3.What is the advantage of educated people according to Paragraph 4?
A.They learn more about human body and medical care.
B.They can set up their own health care system.
C.They are more connected to the society.
D.They are skilled in doing research through social networks.
4.What can we know about reading from the last paragraph?
A.It is effective against cancer.
B.It can change a person’s lifestyle completely.
C.It can help people understand humans brain better.
D.It is beneficial to peoples EQ and brain health.

They just can’t help it! My theory is that the female brain is mainly built for empathy— the ability to understand other people — and that the male brain is mainly built for building systems. 1. For example, women are more likely to read magazines on fashion and parenting, while men will choose magazines that are mainly about computers and sports.
You may think that these preferences are influenced by the way people are taught to behave when they are growing up. However, this is not the case. A new study carried out at the University of Cambridge shows that newborn girls look longer at a face, and newborn boys look longer at a mobile. 2. It has also been observed that girls are better at noticing signs of changes in other people’s feelings. Boys, however, seem to enjoy building toy towers and playing with toys which have clear functions. 3. People whose jobs are in the construction (建设) industries are almost males. Maths and engineering, which require high levels of systems thinking, are also male-chosen disciplines (准则). Why do men and women have differences? Actually women have four times as many brain neurons (神经元) that connect the right and left part of their brains. Because of it, women have the better ability to multitask than men. 4. Men tend to focus on a limited number of problems at a time. They will separate themselves from problems and view tasks as independent from one another.
Some people may worry that I am suggesting one gender (性别) is better than the other, but this is not the case. My theory says that males and females differ in the kinds of things that they find easy, but that both genders have their strengths and weaknesses. 5. It is not true. The study simply looks at males and females as two groups, and asks what differences exist, and why they are there.
A.Generally speaking, there are clear differences.
B.You can see the same kind of pattern in the adult workplace.
C.Their preferences for building systems may change over time.
D.They will consider many sources of information at the same time.
E.That suggests certain differences between male and female brains are biological.
F.It is important to stress that the female brain may be built more for empathy.
G.Others may think the theory creates a belief of what a particular type of person is like.

A study has found that a lifetime of regular exercise and activity can slow down the aging process (衰老过程). Researchers say that getting older should not necessarily mean becoming more weak or sick. Their research shows that a devotion to a life of movement and exercise may help us live not only longer, but also healthier.
For their study, the researchers looked at two groups. The first group was made up of 125 non-professional cyclists between the ages of 55 to 79. This group included 84 healthy men and 41 healthy women. We will call this group the “cyclists”.
Researchers then found 130 people to make up a second group. Within this group, 75 people were aged from 57 to 80. The other 55 were between the ages of 20 and 36. The people in this group were also healthy, but they did not exercise regularly. We will call this group the “non-exercisers”. Smokers, heavy drinkers of alcohol and people with other health issues were not included in the study.
Then, researchers gave both groups a series of tests. They tested their muscle mass (肌肉质量), muscular strength, percentage of body fat and the strength of their immune (免疫的) systems. Then the researchers compared the results of the two groups.
Results showed that the cyclists did not experience body changes usually regarded as a normal aging process. For example, they did not lose muscle mass or muscular strength. Also, their body fat did not increase with age.
The researchers also found something they had not expected. The study showed that the immune systems of the cyclists did not age either.
The researchers advise us all to find an exercise that we like in our lives.
1.How did the researchers carry out the study?
A.By comparing. B.By discussing.
C.By imagining. D.By reasoning.
2.Which of the following is a result of the research?
A.The cyclists kept a thin body shape.
B.The non-exercisers gained weight easily.
C.The cyclists’ muscles remained strong with age.
D.The non-exercisers usually had health problems.
3.Which is an unexpected result for the researchers?
A.The cyclists had normal aging process.
B.The cyclists’ immune systems didn’t age.
C.The cyclists lost nearly all their fat.
D.Everyone needed an exercise in their lives.
4.Which of the following can be the best title for the text?
A.Healthy People Need More Exercise
B.Take an Exercise, the Harder, the Better
C.Cycling Is the Best Way to Prevent Aging
D.A Lifetime of Exercise Slows Aging Process

If you want to live longer and lower the risk of heart disease, a move to the mountains may help. Research by scientists in Greece shows that living in the mountains is good for the heart and longevity(长寿). People living at higher altitude(海拔) have lower possibility of dying from heart disease than those closer to sea level, even if they have factors that could increase their risk. "Residence in mountainous areas seems to have a ‘protective effect’ from heart disease," said Dr Nikos Baibas of the University of Athens. He and his colleagues suspect that the increased exercise from walking up mountainous area gives the heart a good workout and enables it to cope with lower levels of oxygen.
Researchers studied the health records and death rates of 1,150 Greeks who lived in three villages near Athens over 15 years. One village was 1,000 meters above sea level and the other two were in low-lying areas. Although men and women living in the mountainous village had higher blood pressure rates and other risk factors than people in the other villages, they had a lower rate of death from heart disease and other causes after a fifteen year follow-up." The contrast was more evident among men than among women," Baibas added in a report in the Journal of Epidemiology and Community Health. Heart disease is one of the world's top killers. Smoking, high blood pressure, raised cholesterol levels, being overweight and a family history of the illness increase the possibility of developing the disease.
1.The first sentence in the passage is used to ________.
A. give a very good guessing
B. tell readers what the passage focuses on
C. warn people of the risk of heart disease
D. name a new unknown illness
2.According to the passage, a person ________ may have less possibility of having heart attack.
A. from higher altitude
B. with a better living habit
C. with more money
D. in a happier mood
3.How long does the research of the Greeks last?
A. At most 10 years. B. Not mentioned.
C. More than 20 years. D. About 15 years.
4.Apart from altitude, how many factors raise the chance of developing heart disease?
A. three B. four C. five D. six
