To get an extra 14 years of life, don't smoke, eat lots of fruits and vegetables, exercise regularly and drink alcohol in a proper amount.That is according to a study published this Monday in the Public Library of Science Medicine Journal.
After tracking more than 20,000 people aged 45 to 79 years in the United Kingdom from about 1993 to 2007, Kay-Tee Khaw of the University of Cambridge and his colleagues found that people who adopted these four healthy habits lived all average of 14 years longer than those who didn't.
“We've known for a long time that these behaviors are good things to do, but we've not seen this benefit before, ”said Susan Jebb, head of Nutrition and Health at Britain's Medical Research Council.“The benefit was also seen regardless of whether or not people were fat and what social class they came from.”
Study participants(参与者)scored a point each for not smoking, regular physical activity, eating five servings of fruits and vegetables a day and moderate alcohol intake.
Public health experts said they hoped the study would inspire governments to introduce policies helping people to adopt these changes.But because the study only observed people rather than testing specific changes, it would be impossible to conclude that people who suddenly adopted these healthy behaviors would surely gain 14 years.
“We can't say that any person could gain 14 years by doing these things, ”said Dr.Tim Armstrong, a physical activity expert at the World Health Organization.“The 14 years is an average across the population of what's theoretically(理论上地)possible.”
“Most people know that things like a good diet matter and that smoking isn't good for them, ”Susan Jebb said.“We need to work on providing people with much more practical support to help them change.”
小题1:Which of the following DOESN'T belong to the four healthy habits?
A.Eat five servings of fruits and vegetables a day.
B.Do proper exercise in the morning every day.
C.Drinking alcohol in the proper amount every day.
D.Having a cigarette before going to bed every day.
小题2:We can learn from the passage that            
A.Susan Jebb did not take part in the study.
B.the study observed people as well as tested specific changes.
C.there's no need for people under 45 to adopt these good habits.
D.only those from first class can benefit from these healthy behaviors.
小题3:What can be inferred from the passage?
A.All the people are well aware of the harm of their bad habits.
B.People aged 45 to 70 have bad habits in the United Kingdom.
C.Governments should take measures to help people change their bad habits.
D.People have adopted the four healthy habits after knowing they're good.
小题4:What would be the best title for this passage?
A.Smoking and Drinking Cuts You 14 Years
B.How to Live a Much Healthier Life
C.Healthy Habits May Give Extra 14 Years
D.How to Make Your Life Longer Than Others

Health experts have long worried about the increasing rate of obesity in kids. It’s an important concern: Being very overweight or obese during childhood can lead to serious problems normally seen in adults, such as diabetes and high blood pressure. Poor diets and a lack of exercise are usually the causes. But would you ever have imagined there might be a connection between the bacteria that lived in your guts (内脏)when you were a baby and the chance that you would become overweight?
Scientists in Finland recently found just such a link. In a recent study, they showed that overweight kids had different species of bacteria living in their guts.
You probably think of bacteria only as germs that can make you sick. While it’s true that some bacteria can make people ill, your body actually depends on some types of bacteria to help you digest food and extract nutrients from it. These “good” bacteria live in your guts, where they process the food you eat.
Human babies get these bacterial helpers from their moms. When a baby is born, some of the bacteria in the mother move into the baby’s body. Growing babies get additional “good” bacteria from the milk their mothers produce. And it turns out the bacteria might play an important role in regulating weight just six years later.
So how could these bacteria affect weight? The researchers still haven’t tested that question, but future tests might lead to an answer.
小题1:The “link” in Paragraph 2 refers to the relationship between _______.
A.bacteria and the chance of being overweightB.obesity and diabetes
C.diets and the chance of being overweightD.bacteria and exercise
小题2:Which of the following is NOT the function of “good” bacteria?
A.Helping to digest food.B.Helping to take nutrients from food.
C.Helping to regulate weight.D.Making a person ill.
小题3:The purpose of writing this passage is to _______.
A.introduce the role of bacteria in children’s weight
B.analyze the influence of obesity on kids
C.give advice on how to lose weight quickly
D.explain the function of bacteria in foods

I’m glad to find this comment which has some sort of support in this quest(寻求)I have to eat raw(未煮熟的)foods. I’m an unhealthy 49 years old and have come to the conclusion that it’s now or never, so I am taking a dive into the raw eating lifestyle.
I have to cook for my family and prepare what they want to eat. I’m trying to plan out this better so I have some of these unusual foods ready for myself.
I’ve read several books written by Ann Wigmore and like her approach to the living foods.
Last week I attempted fasting(禁食)and failed. I lasted five days by having carrots, spinach, apples and other vegetarian diets I could get my hands on. I was doing fine until I drank some coffee. I kind of proved it in my mind to have the coffee but it only made me excited and then I couldn’t sleep well and felt hungry and weak. So I stopped and went back to the old way of eating with the family.
This week I started to make a drink called rejuvelac made of sprouted wheat(芽麦). This is fairly new to do for me and the drink smelled sort of musty(发霉的)and tasted kind of like a musty lemon. The kids tasted it and almost threw up but surprisingly it tasted good to me. It is supposed to help in digestion(消化).
I’ve made some attempts to grow wheat grass. I think I have figured that out as long as I keep it away from birds and our horses. I have two habits to get rid of, drinking coffee and smoking. I quit smoking last month but something happened, so I started up again. I’m very frustrated(受挫的) with the smoking and really have a desire to quit for good. Anyhow I will keep this updated on my progress.

Bruce Alberts, the former President of the National Academies (USA), has now taken over as Editor-in Chief of Science. Judging by his editorial in this week’s issue Considering Science Education there could be some interesting times ahead in Science offices.
Here’s part of what Bruce has to say about science education…
I consider science education to be critically important to both science and the world, and I shall frequently deal with this topic on this page. Let’s start with a big-picture view. Science has greatly advanced our understanding of the natural world and has enabled the creation of countless medicines and useful devices. It has also led to behaviors that have improved lives. The public appreciates these practical benefits of science, and science and scientists are generally respected, even by those who are not familiar with how science works or what exactly it has discovered.
But society may less appreciate the advantage of having everyone acquire the ways of thinking and behaving that are central to practice of successful science: scientific habits of mind. These habits include a critical attitude toward established claims and a strong desire for logic and evidence. As famous astronomer Carl Sagan put it, science is our best detector (检测器). Individuals and societies clearly need a means to logically test the constant clever attempts to operate our purchasing and political decisions. They also need to challenge what is unreasonable, including the intolerance that led to so many regional and global conflicts.
So how does this relate of science education? Might it be possible to encourage, across the world, scientific habits of mind, so as to create more rational (理性的) societies everywhere? In principle, a strong expansion of science education could provide the world with such an opportunity, but only if scientists, educators, and policy-makers redefine (重新定义) the goals of science education, beginning with college-level teaching. Rather than only conveying what science has discovered about the natural world, as is done now in most countries, we should provide first all students with the knowledge and practice of how to think like a scientist.
小题1: Which of the following is NOT included in the “scientific habits of mind”?
A.A critical attitude toward established claims.B.A strong desire for logic.
C.A clever and active mind.D.A strong desire for evidence.
小题2: What does the underlined phrase “such an opportunity” refer to in the last paragraph?
A.To create more rational societies everywhere.
B.To relate decision-making to science education.
C.To encourage science education around the world.
D.To set right goals of science education.
小题3:In Bruce Alberts’ opinion, which is the most important in science education?
A.Offering all students enough practice to drill their mind.
B.Equipping all students with a thinking model of a scientist.
C.Telling students what science has discovered about the natural world.
D.Advising all students to challenge all established scientific achievements.
小题4:Which of the following would be the best title for this passage?
A.Bruce Alberts, a great science educator
B.Science education and world peace
C.The government and science education
D.Bruce Alberts’ opinion on science education
You'd be forgiven for thinking that running after children each day would leave parents in the best shape of their lives.But a study has found that the mothers and fathers of young children are more unhealthy than their childless peers(同龄人).
Mothers with young children are heavier and eat more calories and fatty foods,and consume more sugary dinks than chidless women,scientists said.And both sexes are less active than those in their age group without children.
Parents often choose quick,easily preparesd foods that are high in fat and calories,and by choosing these foods they may in turn serve them to their children,forming a cycle of unhealthy diet.
Dr.Berge,one of the study authors,said:“This isn't a study about blame,this is about spotting a very high-risk time period for parents that doctors should be aware of ,so they can offer solutions(解决办法).”
According to the study ,mothers ate more fatty foods and drank about seven sugary drinks weekly,equal to about four chidless women.They also had an average of 2,360 calories daily,368 calories more than women without children,With that many calorise,women that age would need to be active to avoid to avoid gaining weight.
Fathers ate about the same amount of daily calories childless men and both had an average boby-mass index(指数),but fathersgot less physical activity—about five hours weekly ,compared to almost seven hours among chidless men.
The study has several limitations-there's no data on how many women reccently had babies.Ther's also no information on the number of single parents,who likely face diet and exercise challenges.Sarah Kriger,an American dietician who works with new mothers said some of the mothers may have had postpartum(产后)depression,which might affect their eating and exercise habits.
小题1:What does the author mainly aim to tell us in the passage?
A.Childless couples live a much happier life than those with children.
B.Mothers will be unhealthy because of the postpartum deprdession
C.Couples of young children eat more fatty foods and lead unhealthier lives.
D.Fathers tend to eat high calorie foods because they should run after thrie children.
小题2:The underlined part“in the best shape”in the first paragraph means that a person  .
A.is busy and tiresB.has a most harmonious family

小题3:Which of the following is NOT mentioned about mothers with children?
A.They are less active
B.They eat unhealthy foods
C.They may feel unhappy aftre having babies
D.They may lose their jobs aftre having babies
小题4:What Dr.Berge says in Paragraph 4 suggests that    .
A.Parents should pay more attention to their chidren
B.doctors should do something with parents'high-risk time period

D.postpartum depression will help mothers to lead a healthier lirf
Bad moods can actually be good for you, with an Australian study finding that being sad makes people less gullible (轻信), improves their ability to judge others and also boosts memory.
The study, authored by psychology professor Joseph Forgas at the University of New South Wales, showed that people in a negative mood were more critical of, and paid more attention to, their surroundings than happier people, who were more likely to believe anything they were told.
"Although positive mood seems to promote creativity, flexibility, cooperation, and reliance on mental shortcuts, negative moods trigger (引发) more attentive, careful thinking, paying greater attention to the external world," Forgas wrote.
"Our research suggests that sadness ... promotes information processing strategies best suited to dealing with more demanding situations."
For the study, Forgas and his team conducted several experiments that started with inducing happy or sad moods in their subjects through watching films and recalling positive or negative events.
In one of the experiments, happy and sad participants were asked to judge the truth of urban myths and rumors and found that people in a negative mood were less likely to believe these statements.
People in a bad mood were also less likely to make snap decisions based on racial or religious prejudices, and they were less likely to make mistakes when asked to recall an event that they witnessed.
The study also found that sad people were better at stating their case through written arguments, which Forgas said showed that a "mildly negative mood may actually promote a more concrete, accommodative and ultimately more successful communication style."
"Positive mood is not universally desirable: people in negative mood are less prone to judgmental errors, are more resistant to eyewitness distortions(扭曲)and are better at producing high-quality, effective persuasive messages," Forgas wrote.
The study was published in the November/December edition of the Australian Science journal.

The key to reaching or staying at a healthy weight is regular exercise and good eating habits. Teens should get 60 minutes or more of physical activity a day. Note the word “activity”. As long as you’re getting your body moving, it doesn’t have to mean doing complicated exercises or going to the gym (体育馆) every day. All that matters is that each week you get the right balance of activity, including aerobic (有氧健身法的) strength building, and flexibility (柔韧性) exercise. Make exercise a habit by scheduling some every day.
On days when you have soccer practice or an aerobics class, you may have no trouble exercising for an hour or more. But most of us are busy, and 60 minutes a day of activity seems like a lot of time. The good news is that it’s OK to divide it into shorter “exercise breaks” throughout the day. Just as you might have a healthy snack to stop yourself getting hungry, exercise snacks can keep energy level high. So get up 15 minutes earlier and do some yoga or other stretching (伸展) activity. Fast walk or jog (慢跑) for 15 minutes at lunch. Do the same thing after school ­­­­­or walk or bike home. Add to that taking the stairs, gym class, and walking between classes during the day, and you’ve probably reached your 60 minutes.
Here are 5 simple ways to make an exercise lifestyle change:
1. Start today. Go outside for a walk.
2. Take the stairs instead of the elevator.
3. Instead of driving, walk or bike to places like school or a friend’s house.
4. Clean your room or wash the car.
5. Limit your time watching TV, using the computer, or playing video games--and when you do play, try some games that get you moving.
小题1: The underlined phrase “exercise snacks” in the second paragraph probably means ________.
A.food eaten before exercise
B.food eaten during exercise
C.shorter “exercise breaks”
D.a new kind of exercise
小题2:Why should we have exercise snacks every day?
A.Because they can stop us getting hungry
B.Because they can keep energy level high
C.Because they can include many kinds of sports
D.Because they are more likely to relate to our daily life
小题3:Which of the following is NOT mentioned in the passage?
A.To go hiking on your holidays
B.To spend less time on computer games
C.To go to school on foot or by bike
D.To do some housework at home
小题4:What will be most probably discussed in the following paragraph?
A.Losing weightB.Good eating habitsC.Exercising your brainD.Outdoors exercise
小题5: What would be the best title for this passage?
A.Regular exerciseB.School exerciseC.Indoors exercise D.Difficult exercises
In the United States, 30 percent of the adult (成年人) population has a “weight problem”. To many people, the case is clear: we eat too much. But scientific evidence(证据)does little to support the idea. Going back to the America of 1910, we find that people were thinner than today. Yet they ate more food. In those days, people worked harder physically, walked more, used machines much less, and didn’t watch TV.
Several modern studies, moreover, have shown that fat people do not eat more on average (平均) than thinner people. In fact, some investigations (调查), such as a 1990 study of 3,545 London office workers, show that fatter people eat less than slimmer people.
Studies show that slim people are more active than fat people. A study by a research group of Stanford University School of Medicine found the following interesting facts:
The more the men ran, the more fat they lost.
The more they ran, the more they ate.
Thus, those who ran the most ate the most, yet lost the greatest amount of body fat.
小题1:What kind of physical problem do many adult Americans have?
A.They are too thin.B.They work too hard.
C.They are too fat.D.They lose too much fat.
小题2:Which of the following words can take the place of the word “slim” in this passage?
A.poorB.thinC.healthyD.rich
小题3:Compared with the adult American population today, the Americans of 1910 ______.
A.ate more food and had more activitiesB.ate less food but had more activities
C.ate less food and had less physical activitiesD.had more weight problems
小题4:What have modern medical and scientific researches reported to us?
A.Fat people eat less food and are less active.
B.Fat people eat more food than slim people but are less active.
C.Fat people eat more food than slim people but are more active.
D.Thin people run less, but have greater increase in food intake.
