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.

Most schools forbid chewing gum(嚼口香糖), but in a few years they might consider changing that rule. Why? Scientists are finding evidence that gum chewing may be good for your health. It may even help improve your test scores. This exciting research is just beginning. And in the meantime, companies are also experimenting with adding vitamins, minerals, medicines, and other substances that could give gum the power to cure headaches and fight everything from serious diseases to bad breath.
Other researchers are finding that gum might work better than a pill to deliver medicines and other substances into the bloodstream. That’s because the lining (膜) of our cheeks can absorb certain substances more quickly than our stomachs and intestines (肠) can. That discovery could help other researchers develop medicine-containing gums that fight colds, ease headaches, battle nervousness, and
more. Scientists might even create anti-microbial (抗菌的) gums that cure bad breath.
Those projects may take years, but gum scientists have already had at least one recent success: They’ve created a gum that could help us stay awake. Researchers have produced a gum called Stay Alert. Each stick has as much caffeine as a cup of coffee. It can take an hour for the caffeine in coffee to have its full effect, but the caffeine in Stay Alert hits in just a few minutes. The gum is easy to transport and it’s stable in cold and hot climates. Unlike a pill, it doesn’t require water to swallow. Those qualities make it easy for soldiers to use. For now, Stay Alert is available only to the military (军队). The manufacturer may one day offer it for sale to the public. People who work at night, such as truck drivers and medical personnel who ride in ambulances, might benefit from a product like Stay Alert.
小题1:The passage mainly talks about _____.
A.the rule of forbidding chewing gum in school
B.new research on chewing gum
C.different kinds of chewing gum
D.the relationship between chewing gum and medicine
小题2:What does the underlined word “hits” in Paragraph 6 probably mean?
A.Touches. B.Attacks.C.Takes effect. D.Affects badly.
小题3:According to the passage, Stay Alert is a gum which can help people _____.
A.stay awakeB.fight colds
C.cure headachesD.overcome nervousness
小题4:It can be inferred from the passage that _____.
A.stay Alert is not easy to store
B.stay Alert needs water to swallow
C.stay Alert is available to the public now
D.we can’t buy gums which cure bad breath now
Beginning in October, more than 13,000 McDonald’s (麦当劳)restaurants in America will use a new variety of cooking oil. McDonald’ s aims to make its French fries (油炸食品) and other fried foods healthier.
The change will not affect the taste or the number of calories in the food. But by changing the cooking oil, McDonald’s says, it hopes to cut by nearly half the amount of trans fatty acids (转换脂肪酸) in French fries and reduce the amount of saturated fats(饱和脂肪) by 16 percent. Scientists believe that trans fatty acids and saturated fats raise cholesterol(胆固醇) levels and increase the risk of heart disease.
McDonald’s new step is important because McDonald’s is an industry leader and other fast-food chains and food processors may follow the lead.
For McDonald’s ,the action comes at a time when Americans are becoming more and more concerned about; obesity (肥胖) and are increasing pressure on food companies to offer healthy and nutritious (有营养的) food to consumers.
After three years of study, McDonald’s officials say they are switching oil that is lower in saturated fats and trans fatty acids. McDonald’s says the change will not cause higher price for consumers.
Though there is some change, scientists say that the amount of trans fat in foods at McDonald’s and at other fast-food companies is still important.
小题1:More than 13,000 McDonald’s restaurants in America will use a new kind of cooking oil to ______________.
A.lower the costs of the products
B.maker its food taste hatter than ever before
C.cure (治愈) the heart disease
D.do good to the health of consumers
小题2:The underlined ward "switching" here has the same meaning as "   _______ ".

A.McDonald’s is a pioneer in food products
B.McDonald’s is enlarging its restaurants in the world
C.fried foods can’t keep up with the development of modem society
D.McDonald’s is to use new cooking oil
小题4:When a new kind of cooking oil is used in McDonald’s,     ________ 
A.the prices of McDonald’s foods will be a tot higher
B.consumers will find the taste of McDonald’s foods different
C.many other food companies will do what McDonald’s does
D.obesity will disappear in American society sooner or later
Feel tired lately? Has a doctor said he can’t find anything wrong with you? Perhaps he has sent you to a hospital, but all the advanced equipment there shows that there is nothing wrong with you.
Then, consider this: you might be in a state of sub-health(亚健康). Sub-health, also called the third state or gray state, is explained as a borderline(界限)state between health and disease.
According to the survey by the National Health Organization, over 45 percent of sub-healthy people are middle-aged or elderly. The percentage is even higher among people who work in management positions as well as students around exam-week.
Symptoms include a lack of energy, depression, slow reactions, insomnia, anger, and poor memory. Other symptoms include shortness of breath, sweating and aching in the waist and legs.
The key to preventing and recovering from sub-health, according to some medical experts, is to form good living habits, alternate work and rest, exercise regularly, and take part in open air activities.
As for meals, people are advised to eat less salt and sugar. They should also eat more fresh vegetables, fruits, fish because they are rich in nutritional elements -- vitamins and other elements that are important to the body.
Nutrition experts point out that it is not good to eat too much at one meal because it may cause unhealthy changes in the digestive tract(消化道). They also say that a balanced diet is very helpful in avoiding sub-health.

Too cold for recess?  School policies vary as much as temps
When is it too cold for schoolchildren to go outside for recess(课间休息)? The answer varies widely based on where a school is located and what the kids are used to.
Consider:  One northern Minnesota school says it has to be 15 below zero before kids are kept inside. But in areas along the East Coast, temperatures below 35 to 40 degrees could keep kids inside. Canceling recess because of the cold is no small issue considering that much of the USA is trembling through what may be its coldest winter in a generation, according to AccuWeather.
There is no national temperature standard for when to keep kids inside during the winter months, the U.S. Department of Education says. Decisions are made at the local level, either by principals or school districts.
Consequently, policies are all over the map:
? In International Falls, Minn., the self-described "Icebox of the Nation," where the average high temperature in January is 13 degrees, Falls Elementary School Principal Jerry Hilfer says, "if it's 15 below (or warmer), they go out, no matter what." "At 20 below, it gets iffy," he adds.
? In Wicomico County, Md., principals typically keep children indoors when temperatures drop below freezing, or if it's raining or snowing, says Susan Jones, the school system's director of elementary education.
"That's the bottom line," says Curtis Twilley, principal of Pemberton Elementary School in Salisbury, Md. Twilley says students get little exercise when recess stays indoors. At Pemberton Elementary, the students will typically play board games or computer games in a classroom because the school's gym is occupied with other classes, he says.
? For schools in Marquette, Mich., which averages about 12 feet of snow per season, school officials acknowledge students are probably a little more prepared than those in some more mild climates.
小题1:Which of the following is not true according to the passage_________.
A.No national temperature standard is made for when to keep kids inside during the winter months.
B.Susan Jones insists students get little exercise when recess stays indoors.
C.In Wicomico County, children are kept indoors when temperatures dip below freezing.
D.Mich has about 12 feet of snow per season on average.
小题2: Which place calls itself Box of Ice?
Wicomico County  B. Marquette    C.Salisbury       D. Minn
小题3: Considering_______, canceling recess In USA because of the cold is a big issue.
A.different schools have different principles.
B.much of the USA has very cold winter.
C.physical activity can boost student performance.
D.decisions are made at the local level,
小题4: The underlined word iffy means _______.
A.uncertain B.surprisingC. seriousD.worse
小题5: What will be talked about next?
A.More school policies
B.The reasons why school policies vary.

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
Exercise is an important part of a healthy life. It reduces your risk of heart attack and is a good way to control body weight. It is also something you can do with other people, which can be great fun. So, it is important to find time to exercise and be healthier. As well as making time to exercises, another way is to build it into the natural rhythm (节奏) of your day.
· Go for a walk on your lunch break.
Try to find at least three different ways and change them throughout the week. It
might even be possible to find a place to walk inside, for those bad weather days.
· Talk to your employers about improving health at work.
Encourage your workers to cycle to and from work. You might also be able to
encourage them to set up a gymnasium. Sell the idea by pointing out that doing so
will improve productivity (生产率), and make workers happy.
· If you are a student.
Go for walks with friends to talk about your studies. Spend some time in the learning
resource centre reading about sport, exercise and health. The more you know, the
more choices you will have about how to be physically active. Most colleges have
sport and exercise programs that students can take part in. Find out which activities
are being held, and try those you think you might enjoy.

Smoking, which may be a pleasure for some people, is a series of discomfort for their fellows. Medical scientists have expressed their concern about effect of smoking on the health not only of those who smoke but also those who do not smoke. In fact, non-smokers who take in the air polluted by tobacco smoke suffer more than the smokers themselves. A great number of students are trying to persuade the university to forbid smoking in classrooms. Believe they are completely right in their aim. However, I think it more important to achieve this by calling on the smokers to use good judgment and to show concern for others. Smoking is not allowed in theaters, cinemas and in other public places. Therefore, smoking must be forbidden in our classroom.
