The effect of having no friends
A study has found that people who are lonely have more physical and mental health problems than those who feel connected with others. It affects your health in four ways.
You are more likely to be depressed (抑郁的).
1. Researchers have shown that when you’re lonely, brain hormones associated with stress such as cortisol (皮质醇) become active, which can cause depression. The previous research has found that the more positive social interactions (交流) people with depression have, the more improvement in symptoms they experience.
2.
Research has shown you’ll eat less healthily if you frequently dine alone. Researchers have pointed out that if you are cooking for other people, you are more likely to prepare a healthier meal that contains a range of foods—meat, starch (淀粉) and vegetables. 3. People who are lonely are also more likely to be physically inactive.
You are more likely to suffer from heart disease.
Research has repeatedly shown lonely people have a higher risk of heart disease, and it’s for many reasons. Since they don’t have social support, they’re more likely to be affected by stress. 4. If they’re lonely, they’re less likely to be physically active or eat properly. If they don’t feel well, they’re much less likely to go to see a doctor.
5.
Research has found that loneliness can affect the immune (免疫的) system. People who are lonely produce more inflammation (发炎)—related proteins in response to stress than folks who feel more socially connected. Inflammation is linked to numerous health conditions including heart disease, Type 2 diabetes, arthritis, and Alzheimer’s disease.
A.You are likely to eat more food.
B.You had better get on well with others.
C.You are less likely to take care of yourself.
D.You could have a weaker system to fight off disease.
E.This increases the possibility of getting heart disease.
F.Otherwise, you’re just throwing something together for yourself.
G.The more lonely you feel, the more likely you are to be depressed.

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.

Smoking is harmful. But as soon as you quit the habit, everything will be OK, right? Wrong.
New research has found that even if you give up smoking, the damage it has done to your genes will stay there for a much longer time. In the research, a team of US scientists studied the blood of 16,000 people. Among them, some were smokers, some used to smoke, and the rest were non-smokers. Scientists compared their genes and found that more than 7,000 genes of smokers had changed－a number that is one-third of known human genes.
According to NBC News, both heart disease and cancer are caused by genetic changes. Some people may have had the changes when they were born, but most people get them in their day-to-day lives while doing things like smoking.
When you stop smoking, a lot of these genes will return to normal within five years.
This means your body is trying to heal (治愈) itself of the harmful effects of smoking. But the changes in some of the genes stay for longer. They can stay for as long as 30 years.It’s almost like leaving a footprint on wet cement (水泥)－it will always be there, even when you’ve walked away and when the cement becomes dry.
Although the study results may make people unhappy, there is a bright side: the findings could help scientists invent medicine to treat genetic damage caused by smoking or find ways to tell which people have heart disease or cancer risks.
1.The purpose of Paragraph 1 is to______ .
A.raise a question
B.give an example
C.make an argument
D.show the main idea of the passage
2.Most genetic changes happen because of______ .
A.people’s condition at birth B.environmental pollution
C.heart disease and cancer D.people’s bad living habit
3.The underlined word “it” in Paragraph 5 refers to______ .
A.the footprint B.the cement
C.the harmful effect D.the genetic change
4.Which of the following statements is true?
A.The findings are the fruit of more than three years’ research.
B.The findings have prevented more people from starting smoking
C.The findings help to find cures for genetic damage caused by smoking.
D.The findings offer evidence that a damaged gene can heal itself.

A research suggests that speaking more than one language may delay different kinds of dementia(痴呆) that is the loss of mental ability. In fact, researchers say, speaking two languages appears to be more important than the level of education in defending against dementia.
A study in India examined the effect of knowing more than one language in delaying the first signs of several dementia. Researchers studied nearly 650 people whose average age was 66. 240 of those studied suffered from Alzheimer's, the most common form of mental decline(下降). 391 of the subjects spoke two or more languages. Researchers found the dementia began about four-and-a-half years later in those who spoke two languages compared to those who spoke only one language. The level of education had no effect on the age at the first sign of dementia.
Thomas Bak, from the Centre of Cognitive Aging at the University of Edinburgh in Scotland, who helped to organize the study, suggests that individuals who speak more than one language train their brains by moving back and forth between different words and expressions. He also believes this effort improves what scientists called executive(执行的) functioning, which often weakens in people with dementia. He states that researchers found there was no extra gain in speaking more than two languages.
Mr Bak says it does not appear important whether you learn another language at a young age or later in life. It's not something that “you missed the boat when you do not do it as a baby.” It is something that is still quite useful and powerful when you do it as an adult.
1.The finding of the study is that .
A.learning more than one language can cure dementia
B.the level of education matters in defending against dementia
C.speaking two languages may delay kinds of dementia
D.people who suffer from dementia will lose mental ability
2.The underlined word “subjects” in Paragraph 2 refers to “______”.
A.notices that were put on about the study
B.people who were studied in the study
C.questions that were asked in the study
D.methods that were used in the study
3.According to Mr Bak, ______.
A.when you learn one more language makes no difference
B.people's executive functioning often strengthens with age
C.the more languages one speaks, the less chance of getting dementia
D.it is much easier to learn one more language at a young age
4.This passage may probably be seen in ______.
A.a research plan B.a business magazine
C.a book review D.a health magazine

A new study has found no evidence that sunscreen, commonly used to reduce the risk of skin caner, actually increases the risk.
Researchers from the University of Yale based their findings on a review of 18 earlier studies that looked at the association between sunscreen use and melanomas (黑素瘤). They said that they found flaws in studies that had reported associations between sunscreen use and higher risk of melanoma.
Most health experts believe that by protecting the skin from the harmful effects of the sun, sunscreen helps prevent skin cancer, which is increasing in incidence (发生率) faster than any other cancer in the United States.
But questions have been raised about sunscreen and whether it may have the opposite effect, perhaps by allowing people to remain exposed to the sun longer without burning.
The researchers said that among the problems with some earlier studies is that they often failed to take into account that those people most at risk for skin cancer—people with fair skin and freckles (雀斑), for example—are more likely to use sunscreen. As a result, it may appear that sunscreen users get cancer more often.
The studies, which generally relied on volunteers to recall their sunscreen use, were also unable to prove how well the products had been applied, said the new study.
1.The underlined word “flaws” in the 2nd paragraph most probably means ________.
A. evidences B. facts C. faults D. failures
2.People with fair skin and freckles ________.
A. seldom use sunscreen B. are more in danger of skin cancer
C. can be free from the harm of the sun D. often expose themselves to the sun
3.We can learn from the passage that ________.
A. sunscreen users get skin cancer more often
B. the volunteers have proved the effect of sunscreen
C. the new study was based on the experiences of volunteers
D. the number of skin cancer patients is increasing in America
4.Which of the following can be the best title for this passage?
A. Sunscreen to Prevent Skin Cancer
B. Sunscreen to Increase Skin Cancer
C. Skin Cancer Caused by Sunscreen
D. Skin Cancer Caused by Freckles

Dreaming is believing, claim researchers of a new study, who found that dreams have an effect on people’s behavior, judgment and they might contain important hidden truths as well.
“Psychologists’ interpretations (解释) of the meaning of dreams vary widely. But our findings show that people believe their dreams provide meaningful insight (见识) into themselves and their world,” said a lead author of the study Carey More wedge, an assistant professor at Carnegie Mellon University.
In six different studies, researchers surveyed nearly 1,100 people about their dreams. One of the studies focused on general beliefs about dreams and involved 149 university students. All students were asked to rate different theories about dreams. The experts found that a surprising majority of the participants supported the theory about dreams revealing (揭示) the hidden truths about themselves and the rest of the world.
In a second experiment, they surveyed 182 people at a Boston train station, and asked them to imagine one out of four possible situations that could have occurred the night before a scheduled airline trip. Most of the participants said that dreaming of a plane crash would be more likely to affect their travel plans than would just thinking about a crash, or being warned by the government of a terrorism risk. They said a dreamed crash would influence their travel plans just as much as learning about a real crash on their planned route would.
Another experiment involved 270 men and women from across the United States. In a short online survey, they were asked to recall one of the dreams they had seen about any person they knew. The findings showed that people were more likely to remember and describe pleasant dreams about a person they liked, rather than a person they disliked. Meanwhile, in most cases they tended to consider an unpleasant dream as more meaningful if it was about a person they disliked.
“In other words,” said More wedge, “people attribute (归因于) meaning to dreams when it corresponds (与……一致) with their pre-existing beliefs and desires.” The researchers say that more investigation (研究) is needed to fully understand how people interpret their dreams. According to More wedge, most people realize that dreams are not predicting their future, but they still try to find some meaning in there.
1.The purpose of the studies is to _______.
A. determine when people tend to remember their dreams
B. research whether dreams have anything to do with real life
C. find out how people interpret their dreams and what impact that has
D. understand what causes people to dream and how to interpret dreams
2.According to the second experiment, what might influence people’s travel plans most?
A. Thinking about a past plane crash.
B. Dreaming about a plane crash.
C. Hearing a government’s warning of a terrorism risk.
D. Imagining a plane crashing on their planned route.
3.What can be concluded from the study?
A. When a dream conflicts with people’s existing beliefs and desires, they tend to attribute less
meaning to it.
B. Most people disagree that dreams help them better know themselves and the world.
C. A majority of people believes that dreams can predict their future and try to find their meaning.
D. Dreams can be a useful tool for learning and problem solving.
4.Which kind of dream is seen as more meaningful than the rest?
A. A pleasant dream about a person the dreamer likes.
B. A pleasant dream about a person the dreamer dislikes
C. An unpleasant dream about a person the dreamer likes.
D. An unpleasant dream about a person the dreamer dislikes.

If you think English means endless new words, difficult grammars and sometimes strange pronunciations, you are wrong. Haven’t you noticed that you have become smarter since you started to learn a language?
According to a new study by a British university, learning a second language can lead to an increase in your brain power. Researchers found that learning other languages changes grey matter. This is the area of the brain which processes information.It is similar to the way that exercise builds muscles.
The study also found the effect is greater when the younger people learn a second language. A team led by Dr. Andrea Mecheli, from University College London, took a group of Britons who only spoke English.They were compared with a group of “early bilinguals” who had learnt a second language before the age of five, as well as a number of later learners.
Scans showed that grey matter density in the brain was greater in bilinguals than in people without a second language. But the longer a person waited before mastering a new language, the smaller the difference.
“Our findings suggest that the structure of the brain is changed by the experience of learning a second language, ”said the scientists. It means that the change itself increases the ability to learn.
Professor Dylan Vaughan Jones of the University of Wales, has researched the link between bilingualism and maths skills.“Having two languages gives you two windows on the world and makes the brain more flexible (灵活的), ”he said, “You are actually going beyond language and have a better understanding of different ideas.”
The findings were matched in a study of native Italian speakers who had learned English as a second language between the ages of 2 and 34. Reading, writing, and comprehension were all tested.The results showed that the younger they started to learn, the better. “Studying a language means you get an entrance to another world, ” explained the scientists.
1.The main subject talked about in this passage is ________.
A.science on learning a second language B.man’s ability of learning a second language
C.language study can help improve brain power D.language learning and maths study
2.In the second paragraph, the writer mentions “exercise” in order to ________.
A.say language is also a kind of physical labor
B.prove that one needs more practice when he (she) is learning a language
C.show the importance of using the language when you learn it
D.make people believe language learning helps grey matter work well
3.The word “bilinguals” (Paragraph 3) probably means ________.
A.researchers on language learning B.second language learners
C.persons who can speak two languages D.active language learners

While retiring ahead of time may be easier on the body, a new set of research has found that it may not be so beneficial to the mind. The study, carried out at Binghamton University, finds that an early retirement can speed up the usual rate of cognitive (认知的)decrease among the elderly.
The research team studied China's new rural pension (退休金)system, as well as China's most recent Retirement Longitudinal Survey ( CHARLS), in order to look into the effects of early retirement and pension benefits on individual cognition among adults over the age of 60. After going over all of the data, the research team noted a clear direction: people receiving pension benefits were experiencing much more rapid mental decline (智力下降)than those still on the workforce. Surprisingly, women seemed to experience even sharper mental decline after retiring early. Overall, the results support the view that decreased mental activity speeds up cognitive decline.
Nikolov, the lead researcher, had actually carried out former studies that found retirement led to a number of physical health benefits for retirees, such as improved sleep patterns, less stress, and reduced alcohol consumption. However, retirement also usually goes with a decline in social activities and less communication with people, which has also been linked to cognitive decline.
“For cognition among the elderly, it looks like the bad effect on social connection is more than the good effect of the program on fitness and sleep,” Nikolov says. “ Or social connection may simply be the single most powerful factor for cognitive performance in old age.”
The research team are hopeful that their findings will be considered by older adults when thinking about retirement, but perhaps more importantly, they hope that policy makers in developing countries take note while drawing up new pension plans. They suggest building social get-togethers and work shops for recent retirees to help cut down the decline in social communication and creative thinking that often comes along with retirement.
1.Which of the following best describes retiring ahead of time for the mind?
A.Useless. B.Beneficial. C.Damaging. D.Improving.
2.Who mentally suffered most according to the research?
A.Men retiring on former plan. B.Women over the age of 60.
C.Men retiring ahead of time. D.Women retiring early.
3.What will retirement bring to the elderly?
A.Shorter sleep time. B.Fewer social activities.
C.More financial stress. D.Less time with family members.
4.What can we learn about the research team's suggestion?
A.The government should make new policy.
B.People should build more shops for the elderly.
C.The retirement in developing countries should be common.
D.The newly retired people should communicate more.

Hong Kong is among the cities which have the largest populations in the world, but with night skies around 1,000 times brighter than globally accepted levels, it gains a bad reputation(名声) for its light pollution.
A study by Hong Kong University found that brightness levels in the southern Chinese city's popular shopping district of Tsim Sha Tsui were 1,200 times greater than the international dark sky standard.
The crowded city of 7 million people, full of residential(住宅的) high-rises, towering office blocks and neon(霓虹灯) advertisements has no laws to control outdoor lightning.
The result is that light pollution is thought to be much worse than in other large cities, including London, Sydney, Tokyo and Shanghai.
“In Hong Kong, you can't go anywhere outdoor in the evening without your eyes being blinded by this really upsetting outdoor lightning,” the light pollution survey's head Jason Pum told AFP.
“The fact that we have all this light in the sky means energy is wasted,” he said, adding that too much artificial lightning also affects nightly wildlife.
Research has suggested that light pollution can cause a number of harmful health problems in humans, including sleeplessness and headaches and can also affect body clocks and hormones(荷尔蒙).
The university's survey, the result of five million measurements taken from points across the city, was released just days before the start of the yearly Earth Hour event, organized by the World Wildlife Fund.
People around the world will be encouraged to turn off the lights for an hour on Saturday night to advertise climate change. Last year, a number of Hong Kong's major buildings along Victoria Harbour went dark to mark Earth Hour.
“Anyway, we should do our best to reduce the amount of lightning and suit it to the benefit of the environment.”
1.If you walk out at night in Hong Kong, you can see all those things except ______.
A.neon advertisements B.residential buildings
C.a dark sky with many stars D.high office blocks
2.Which of the following statements about too much lightning is NOT true?
A.Too much lightning means wasting energy. B.It can make the city more beautiful at night.
C.It may have a bad effect on nightly wildlife. D.It can do great harm to human beings' health.
3.We can know from the passage that__________
A.Earth Hour is simply organized to reduce pollution. B.light pollution is the biggest problem in Hong Kong.
C.light pollution is the primary causes of sleeplessness. D.light pollution in Hong Kong is among world's worst.
4.What will the author probably discuss after the last paragraph?
A.Ways to reduce light pollution B.Causes of light pollution
C.Worries about light pollution D.Bad effects of light pollution
