Most children, even the youngest of children, are delighted to be around cats and dogs. But these pets carry plenty of germs and allergens（過敏原）, prompting researchers to ask: Are cats and dogs really safe for children？
A study finds that, contrary to many parents’ fears, owning cats or dogs does not increase a child’s risk of developing allergies, and in fact, may actually protect them. The study’s lead author, Dr. Dennic Ownby of the Medical College of Georgia, says that even he was “very surprised” by the results. Ownby and colleagues followed more than 470 children from birth to age 6 or 7, comparing those exposed to cats and dogs during their first year of life to those who were not.
By using skin-prick tests for detecting common allergies, the researchers found that, contrary to what many doctors had been taught for years, children who had lived with a pet were not at greater risk.
Even more remarkable, children who had two or more dogs or cats had an even greater reduction, up to 77 percent, in risk of allergies. Researchers suggest this protective effect may be the result of early exposure to lots of bacteria that are carried by dogs and cats. Exposing young children to these bacteria helps "exercise" their immune systems early in life so that they're better able to resist allergic diseases later.
There's something very important in that first year of life when the immune(免疫) system is developing that we can retrain it away from an allergic response, said Dr. William Davis.
And while researchers are not encouraging parents to buy dogs or cats just to reduce a child’s allergy risk, they say if a family already has one or more animals, there's no need to get rid of them.
【小題1】Why do the researchers feel “very surprised” by the results of the study?

A．Because the results are contrary to their expectation．

B．Because so many children are playing with cats and dogs．

C．Because parents are so much worried about their children．

American children are not the only couch potatoes with nearly one third of children globally spending 3 hours a day or more watching TV or on computers, according to the study of over 70,000 teens in 34 nations.
From Argentina to Zambia, Regina Guthold of the World Health Organization in Geneva and her colleagues found most children were not getting enough exercise and that it made no difference whether they live in a rich or a poor country. “With regards to physical levels, we didn’t find much of a difference between rich and poor countries,” Guthold said, “Growing up in a poor country doesn’t necessarily mean kids get more physical activities.”
The researchers defined adequate physical activity as at least an hour of exercise outdoors for at least 5 days a week. Children spending 3 or more hours a day watching TV, playing computer games or chatting with friends were classified as sedentary.
The researchers found only a quarter of the boys and 15 percent of the girls were getting enough exercise by these definitions. A quarter of boys and nearly 30% of girls were sedentary and didn’t get enough exercise with girls less active than boys in every country aside from Zambia.
Girls from India were the most active with 37 percent meeting exercise recommendation, while girls from Egypt were the least active with 4 percent getting enough exercise. Children in Myanmar were the least sedentary while the most sedentary nations were St .Lucia and the Cayman Islands.
People show deep concern for kids’ lack of physical activity in various nations. Why do they have a low level of physical activity? Guthold speculated（認(rèn)為）that urbanization could be a factor as well as easy access to cars and TVs.
【小題1】If you are sedentary, you ____________.

Eco City Farms(生態(tài)城市農(nóng)場) are becoming more popular in cities and towns around the Unites States.
Eco City Farms in Edmonton, Maryland, is located near shopping centers, car repair shops and homes. The neighborhood is a working-class community(社區(qū)). People do not have very much money. And they have limited access to fresh food in markets.
Over the past two years, the farm has attracted volunteers from the community like Marcy Clark. She schools her four children at home. On a recent day she brought them to Eco City Farms for a lesson. Her son Alston Clark thinks his experience is very valuable.“I like coming out here,”he says,“You know, you connect with the earth, where your food comes from. You appreciate the food a little bit more.”
Margaret Morgan started Eco City Farms. She thinks of it as a place where people can learn to live healthier lives. “Growing food in a community brings people together,”she continues,“Every piece of what we do here is a demonstration(示范) to show people everything about how to have an eco-friendly community.”she says. From the Eco City Farms people come to know that they are not only growing food and raising chickens and bees, but improving the soil with compost(肥料)made from food waste.
Eco City Farms is an experimental operation. The farm gets its power not from the local electricity networks, but from the sun with solar panels. In winter, the green house use a geothermal(地?zé)?system.
Vegetables can be grown all year. So once a week, all winter long, neighbors like Chris Moss and her three children bike to the farm to pick up a share of the harvest.
“I like eating the vegetables ”say five-year-old Owen Moss.

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(chǎn) new study finds different particulates in South China

B．a(chǎn)ir 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＿．

October 15th is Global Handwashing Day．Activities are planned in more than twenty countries to get millions of people in the developing world to wash their hands with soap．
Experts say people around the world wash their hands but very few use soap at so-called critical moments．These include after using the toilet, after cleaning a baby and before touching food．
Global Handwashing Day is the idea of the Public-private Partnership for handwashing with soap．The goal, they say, is to create a culture of handwashing with soap．The organizers say all soaps are equally effective at removing disease-causing germs．They say the correct way to wash is to wet your hands with a small amount of water and cover them with soap．Rub it into all areas, including under the fingernails．Then, wash well under running water．Finally, dry your hands with a clean cloth．
The Partnership says soap is important because it increases the time that people spend washing．Soap also helps to break up the dirt that holds most of the germs．And it usually leaves a pleasant smell, which increases the chances that people will wash again．
It also says that washing hands with soap before eating and after using the toilet could save more lives than any medicine．It could help reduce cases of diarrhea, which is the second leading cause of child deaths, killing more than one and a half million children a year, by almost half．
【小題1】What does the author intend to tell us in the passage?

A．To keep healthy by washing hands．	B．To wash hands with soap．

Bad teeth can be painful and even be deadly. Infections of the gums(牙齦) and teeth can release bacteria into the blood system. Those bacteria can increase the chance of a heart attack or stroke and worsen the effects of other diseases. And adults are not the only ones at risk. For example, a 12­year­old boy died when a tooth infection spread to his brain in 2007 in Washington. Experts said it might have been prevented had he received the dental care he needed.
Experts say good dental care starts at birth. Breast milk, they say, is the best food for the healthy development of teeth. Breast milk can help slow bacterial growth and acid production in the mouth. But dentists say a baby's gums and early teeth should be cleaned after each feeding by using a cloth with a little warm water. Experts say if you decide to put your baby to sleep with a bottle, give only water.
When baby teeth begin to appear, you can clean them with a wet toothbrush. Dentists say it is important to find soft toothbrushes made especially for babies and to use them very gently. The use of fluoride(氟化物) to protect teeth is common in many parts of the world. For example, it is often added to drinking water supplies. The fluoride mixes with enamel(釉質(zhì)), the hard surface on teeth, to help prevent holes from forming.
But young children often swallow toothpaste when they brush their teeth. The American Academy of Pediatric Dentistry notes that swallowing fluoridated toothpaste can cause problems. So young children should be carefully watched when they brush their teeth. And only a small amount of fluoridated toothpaste, the size of a pea, should be used.
Parents often wonder what effect finger sucking might have on their baby's teeth. Dental experts generally agree that this is fine early in life. Most children stop sucking their fingers by the age of four. If it continues, experts advise parents to talk to their children's dentists or doctors. Because it could interfere_with the correct development of permanent teeth.
Dentists say children should have their first dental visit at least by the time they are one year old. They say babies should be examined when their first teeth appear—usually at around six months.
【小題1】According to the passage，what is the function of fluoride?

A．Making the surface on teeth much cleaner.

B．Protecting gums from being infected.

C．Keeping holes on teeth from forming.

D．Slowing down bacterial growth and acid production.

A．To warn us of the deadly infections of gums and teeth.

B．To introduce the advantages of fluoridated toothpaste.

C．To draw our attention to the dental care of young children.

D．To present the research results about dental care.

Are you stressed out, scared or worried all the time? Do you avoid going to certain places, seeing friends or doing certain things because of your worries? Do your worries keep you awake at night? If you’ve answered yes, you may be suffering from anxiety.
Anxiety is a normal and necessary part of life. Anxiety is your brain’s way of telling you about danger. It is anxiety which helps you jump out of the way if a car is speeding towards you. But if it gets out of hand, anxiety can get in the way of your getting on with life and can become a real problem. If this is the case for you, treatment may be a helpful way for you to get your anxiety under control.
Anxiety is a normal part of life. Some people may feel uneasy if moving to a new place and some may get overly anxious in certain situations. There are lots of reasons for this. One main reason is after a stressful thing which has happened in your life. So, if you are involved in a car crash, it’s quite likely that you will be more worried than other people around cars and driving.
Being anxious also probably runs in families. If your parents suffer from anxiety then you are more likely to be anxious too. This is probably partly due to genetics, and partly because of how things are when you’re growing up.
Even though people don’t talk about it much, anxiety is one of the most common mental health problems. About 1 in 4 people will have an anxiety problem at some time in their life.
If you have an anxiety problem it’s hard for other people to understand why something that doesn’t worry them, like being in a crowd of people, can be so scary for you. This can make you feel separated and lonely, as may become worse and worse.
The good news is there are lots of excellent treatments available for anxiety. These include taking therapies (療法) and drugs.
【小題1】Which of the following statements is true about anxiety?

A．With anxiety you are far away from traffic accidents.

When you think of the tremendous technological progress we have made, it’s amazing how little we have developed in other respects. We may speak contemptuously of the poor old Romans because they relished the orgies of slaughter that went on in their arenas. We may despise them because they mistook these goings on for entertainment. We may forgive them condescendingly because they lived 2000 years ago and obviously knew no better. But are our feelings of superiority really justified? Are we any less blood-thirsty? Why do boxing matches, for instance, attract such universal interest? Don’t the spectators who attend them hope they will see some violence? Human beings remains as bloodthirsty as ever they were. The only difference between ourselves and the Romans is that while they were honest enough to admit that they enjoyed watching hungey lions tearing people apart and eating them alive, we find all sorts of sophisticated arguments to defend sports which should have been banned long age; sports which are quite as barbarous as, say, public hangings or bearbaiting.
It really is incredible that in this day and age we should still allow hunting or bull-fighting, that we should be prepared to sit back and watch two men batter each other to pulp in a boxing ring, that we should be relatively unmoved by the sight of one or a number of racing cars crashing and bursting into flames. Let us not deceive ourselves. Any talk of ‘the sporting spirit’ is sheer hypocrisy. People take part in violent sports because of the high rewards they bring. Spectators are willing to pay vast sums of money to see violence. A world heavyweight championship match, for instance, is front page news. Millions of people are disappointed if a big fight is over in two rounds instead of fifteen. They feel disappointment because they have been deprived of the exquisite pleasure of witnessing prolonged torture and violence.
Why should we ban violent sports if people enjoy them so much? You may well ask. The answer is simple: they are uncivilized. For centuries man has been trying to improve himself spiritually and emotionally – admittedly with little success. But at least we no longer tolerate the sight madmen cooped up in cages, or public floggings of any of the countless other barbaric practices which were common in the past. Prisons are no longer the grim forbidding places they used to be. Social welfare systems are in operation in many parts of the world. Big efforts are being made to distribute wealth fairly. These changes have come about not because human beings have suddenly and unaccountably improved, but because positive steps were taken to change the law. The law is the biggest instrument of social change that we have and it may exert great civilizing influence. If we banned dangerous and violent sports, we would be moving one step further to improving mankind. We would recognize that violence is degrading and unworthy of human beings.

    Feel tired lately?Has a doctor said he can’t find anything wrong with you?Perhaps he sends you to a hospital,but all the advanced equipment there shows there is nothing wrong with you.
Then,consider this:you might be in a state of sub-health(亞健康).
Sub-health,also called the third state or gray state,is explained as borderline state between health and disease.
According to the investigation by the National Organization,over 45 percent of sub-health 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(征兆)include a lack of energy,depression,slow reactions,insomnia(失眠),agitation, 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 trace elements(微量元素)—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.
【小題1】When you are in a state of sub-health,you should ________.

As a nation we are becoming more aware of the food we and our children are eating.The recent campaign to improve school dinners by celebrity(名人) chef Jamie Oliver has helped raise awareness of our fast food lifestyles.While we may be trying to eat more healthily，it seems we still have some bad habits.
?Healthy eaters or just trendy?
Are there certain things that you do and don’t eat and why？With so many food programmes and books telling you what you should and shouldn’t eat to be healthy，it’s hard to make choices.
Some people are vegetarians for moral reasons，some don’t like the taste of meat and there are one or two people who do it because it’s trendy.Likewise，it can be trendy to follow the latest celebrity’s diet because it’s what the famous are doing.
?Eating out
People are eating out more often now，not just on special occasions as in the past.The choice of restaurants has also diversified.Italian，Chinese and Indian restaurants have been around for years but have now been joined by Mongolian，Japanese，Mexican and so on.Bars and pubs are still popular for food and often promote English cuisine made with local produce.
“We enjoy eating out a couple of times every month whether with friends or just as a couple.We like trying new things so we go to different restaurants.” said Craig,25，County Durham.
?Eating on the go
From chocolate bars to sandwiches more people are eating on the go—on the street，in cars or on buses and trains.While our parents and grandparents may frown at this behaviour，considering it to be bad manners，people eat on the go because they are rushing from one place to another.And in the home the number of people sitting down at a dining table for their evening meal is on the decrease as meal times become more informal.
“If I’m running late for work I don’t think twice about eating toast in the car or on the bus but I know my mum wouldn’t approve，” said Stacey,24.
