A recent study suggests that teens’ relationship with parents, friends and teachers may have a lot to do with why they don’t get a good night’s sleep.
David Maume, a sociologist and sleep researcher, analyzed federal health data, which interviewed 974 teenagers when they were 12, and then again at 15. He found that family dynamics (动态) have much to do with how well kids sleep. Teens, who had warm relations with their parents and felt like they could talk to them or their parents were supportive of them, tended to sleep better. However, families that were going through a divorce or a remarriage tended to affect teens’ sleep.
And problems at school also affected teens’ sleep. Feeling safe at school and having good relations with teachers tended to promote better sleep. As did good relationships with friends. Kids who took part in sports or other positive social activities or shared similar academic goals with their friends were also more likely to get a good night’s sleep.
These add up to what makes lots of sense: a general feeling of well-being helps teens sleep. If we’re happy and contented, we’re much more likely to sleep better than if we’re sad and anxious.
Now, of course, teens can hardly resist being drawn to their computers and social networking. Maume also found that when parents were strict not only about bedtime, but also about limiting technology, kids slept better. It’s a finding that seems obvious, but parents really do matter when it comes to health habits of their teenagers.
Clearly, teenagers aren’t getting 9 to 10 hours a night, which puts them at risk for all the consequences of lack of sleep, including poor academic performance, colds and stress.

Preface to the fourth edition
A practical English Grammar is intended for intermediate(中级的) and post-intermediate students. We hope that more advanced learners and teachers will also find it useful.
The book is a comprehensive survey of structures and forms, written in clear modern English and illustrated with numerous examples. Areas of particular difficulty have been given special attention. Differences between conversational usage and strict grammatical forms are shown but the emphasis is on conversational forms.
1. Explanation and examples have been brought up to date.
2. There is now more information on countable and uncountable nouns, attributive and predicative adjectives, adverbs of places, sentence adverbs, cleft sentences, prepositions, conjunctives, modal verbs, perfect tenses, infinitive constructions, the passive, purpose clauses and nouns.
In the fourth edition the main changes are as follows.
3. Some material has been rearranged to make comparisons easier. For example, parts of chapters on can, may, must etc. are now grouped by functions; verbs of liking and preference have a chapter to themselves; suggestions and invitations have joined the chapter on commands, requests and advice.
4. The contents list now summaries every edition heading, and there is a new index containing many more entries references.
In this edition the sign “～” is frequently used to show a change of speaker in examples of dialogue. Note also that although the sign “＝”sometimes connects two words or expressions with the same meaning, it is often used more freely, e.g. to indicate a transformation from active to passive or direct to indirect speech.
We wish to thank all at Oxford University Press who have assisted in the preparation of the fourth edition. We would also like to thank Professor Egawa of Nihon University, Japan, Professor Rene Dirven of Duisburg University, West Germany and other colleagues for their friendly and helpful suggestions.

The Diet Zone: A Dangerous Place
Diet Coke, diet Pepsi, diet pills, no-fat diet, vegetable diet… We are surrounded by the word “diet” everywhere we look and listen. We have so easily been attracted by the promise and potential of diet products that we have stopped thinking about what diet products are doing to us. We are paying for products that harm us psychologically and physically（身体上）.
Diet products significantly weaken us psychologically. On one level, we are not allowing our brain to admit that our weight problems lie not in actually losing the weight, but in controlling the consumption of fatty, high-calorie, unhealthy foods. Diet products allow us to jump over the thinking stage and go straight for the scale（秤）instead. All we have to do is to swallow or recognize the word “diet” in food labels.
On another level, diet products have greater psychological effects. Every time we have a zero-calorie drink, we are telling ourselves without our awareness that we don’t have to work to get results. Diet products make people believe that gain comes without pain, and that life can be without resistance and struggle.
The danger of diet products lies not only in the psychological effects they have on us, but also in the physical harm that they cause. Diet foods can indirectly harm our bodies because consuming them instead of healthy foods means we are preventing our bodies from having basic nutrients(营养成分). Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products. Diet products may not be nutritional, and the chemical that go into diet products are potentially dangerous.
Now that we are aware of the effects that diet products have on us, it is time to seriously think about buying them. Losing weight lies in the power of minds, not in the power of chemicals. Once we realize this, we will be much better able to resist diet products, and therefore prevent the psychological harm that comes from using them.
【小题1】From Paragraph 1, we learn that ________.
| A．diet products fail to bring out people’s potential |
| B．people are fed up with diet products |
| C．people have difficulty in choosing diet products |
| D．diet products are misleading people |
| A．hesitate before they enjoy diet foods |
| B．pay attention to their own eating habits |
| C．watch their weight rather than their diet |
| D．try out a variety of diet foods |
| A．losing weight is effortless |
| B．diet products bring no pain |
| C．it costs a lot to lose weight |
| D．diet products are free from calories |
| A．lack basic nutrients | B．are over-consumed |
| C．are short of chemicals | D．provide too much energy |

Air pollution is a leading cause of cancer and classified among Group 1,or top, human carcinogens (致癌物质), said the International Agency for Research on Cancer (IARC), which is the World Health Organization's (WHO) cancer agency, on Oct 17,2013.
The most widely used system for classifying carcinogens comes from the IARC, which places them into five groups. Group 1 carcinogens definitely cause cancer in humans. Group 2A is probably carcinogenic to humans, Group 2B is possibly carcinogenic, the carcinogenicity of Group 3 in humans is unclassifiable, and Group 4 is probably not carcinogenic to humans. Only a little more than 100 are classified as Group 1 cancer-causing substances, including ultraviolet radiation and tobacco smoke.
“Our task was to evaluate the air everyone breathes rather than focus on specific air pollutants,” the lARC's Dana Loomis said in a statement. “The results from the reviewed studies point in the same direction: the risk of developing lung cancer is significantly increased in people exposed to air pollution.”
In 2010, lung cancer resulting from air pollution killed 223,000 people worldwide, and there was also convincing evidence that it increases the risk of bladder (膀腕) cancer, according to the IARC.
Air pollution is already known to raise risks for a wide range of illnesses, including respiratory and heart diseases.
Air pollution is global, although the levels of it vary over space and time.
Loomis said people in Asia, eastern North America, some places in Central America and Mexico, as well as North Africa have relatively high exposure. Developing countries with large populations and booming manufacturing sectors, such as China, are particularly at risk.
Many cities in China, such as Beijing, frequently see smog. This week, Harbin, the capital city of Heilongjiang province, became the first Chinese city to officially suspend classes due to serious smog
Many developed countries face similar problems, although to a lesser degree than most developing nations. In Europe, levels of many pollutants have fallen. But between 91 and 96 percent of Europeans living in cities are exposed to levels of PM2.5—tiny particles with a diameter of less than 2.5 micrometers—that are higher than the WHO safety limits, says a report published by the European Environment Agency on Oct 15.
Although both the composition and levels of air pollution can vary dramatically from one location to the other, the 1ARC said its conclusions apply to all regions of the world.
“Given the scale of the exposure affecting people worldwide, this report should send a strong signal to the international community to take action without further delay,” said Christopher Wild, director of the IARC.
【小题1】What might be the best title of the passage?
| A．Signals of air pollution |
| B．Safety limits of air pollution |
| C．Air pollution, cancer risk |
| D．Air pollution, smog risk |
| A．To focus on cancer-causing substances. |
| B．To evaluate the air quality. |
| C．To study the developing risk of cancer. |
| D．To send signals to the international community. |
| A．The composition and levels of air pollution vary from place to place. |
| B．More and more people in developing countries are exposed to air pollution. |
| C．Developed countries face air pollution, the level of which is higher than the safety limits. |
| D．A large number of people worldwide are exposed to air pollution. |

Car crashes are the top killer of American teenagers．Most of the crashes result from distracted driving not paying attention to the road．
Ryan Didone was a fifteen-year-old passenger in a car that hit a tree．He was one of the nation's more than thirty thousand victims of traffic crashes in 2008．Nearly four thousand deaths, about twelve percent, involved drivers aged fifteen to twenty．Ryan's father, Thomas Didone, is a police captain in Montgomery County, Maryland．He said, "It was an inexperienced, immature driver who felt that he was invincible(不可战胜的), driving at night with a carload of kids．He was distracted, he was going too fast, and it ended up causing one death and some upsetting experiences and tragedy for the rest of the community."
Jim Jennings from the Allstate Insurance Company said "The number one cause of distracted-driving accidents is the mobile phone．Talking on the phone or reaching for it is like drinking four beers and driving．If you're texting while driving, you are twenty-three times more likely to get into an accident than somebody who isn't．
Reaching for a cell phone when it's going off, you're nine times more likely to get into an accident than normally driving," The insurance industry recently held a safety event near Washington for teen drivers．
At first, nineteen-year-old Kevin Schumann easily avoided large, inflatable dolls thrown in front of the car to represent children．He also avoided orange cones representing the edge of the road．Then, as part of the test, he started texting. He hit several cones and at least one doll．
Debbie Pickford from the Allstate Insurance Company said, "Teens are especially at risk from distracted driving—and not just because they lack experience on the roads．What we know from research on teen brain development, is that teens don't really have fully developed brains until they are twenty-five years old. You put those two things together and you get a much, much higher risk.”
【小题1】According to the passage, _____is the most likely to lead to a traffic accident while you are driving．
| A．texting on the mobile phone | B．reaching for a cell phone． |
| C．talking on the mobile phone | D．bringing along a cell phone |

People who are cheerful and relaxed are less likely to suffer from colds. It’s possible that being full of vim and vigor helps the body fight illnesses, say the researchers from Carnegie Mellon University (CMU) in Pittsburgh.
“We need to take more seriously the possibility that a positive emotional style is a major player in disease risk,” says psychologist Sheldon Cohen, the study’s lead researcher.
In a previous study, Cohen and his colleagues found that people who tended to be cheerful and lively were least likely to develop sniffles, coughs, and other cold symptoms(症状).
Those findings were interesting, but they didn’t prove that a person’s attitude affects whether he or she gets sick. Instead, it was still probable that a person’s underlying personality is what matters.
Evidence suggests, for instance, that certain people are naturally more likely to be outgoing and optimistic, with high self-respect and a sense of control over life. This would mean that who we are, not how we feel, finally decides our chances of catching colds.
To figure out which mattered more (personality or emotions), the CMU team interviewed 193 healthy adults. The researchers talked to each person over the phone every evening for 2 weeks. They told the researchers about the positive and negative feelings they had experienced that day.
The results showed that everyone in the study was equally likely to get infected. Their symptoms, however, differed depending on the types of emotions that they had reported over the previous 2 weeks.
Among those who reported good moods and had been infected with the flu virus, for example, 28 percent developed coughs and stuffy(堵塞)noses. On the other hand, those symptoms struck 41 percent of people who had been less positive. Scientists argue about whether negative emotions or positive emotions have a stronger effect on how healthy we are. For now, it can’t hurt to look on the bright side more often than not!
【小题1】What is the text mainly about?
| A．how to get rid of colds | B．Attitude determines life |
| C．Smiles turn away colds | D．Different opinions about colds |
| A．ignorant | B．well-informed | C．energetic | D．in low spirits |

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.

A new study has found evidence of aggressive (攻击性的) behavior in children who drink four or more servings of soft drinks every day. Information for the study came from the mothers of 3,000 5-year-olds. Researchers asked the women to keep a record of how many servings of soft drinks their children drank over a two-month period. They were also asked to complete a checklist of their children’s behavior.
The researchers have found that 43 percent of the children drink at least one daily serving of soda, and 4 percent of the youngsters have even four or more sodas to drink every day.
Shakira Suglia, a famous expert, says they’ve found that children who drink the most soda are more than twice as likely as those who drink no soda to show signs of aggression.
“For the children who consume four or more soft drinks per day, we see more withdrawn behaviors, which make them hard to get along well with others.”
The aggressive behaviors include destroying possessions belonging to others, taking part in fights and physically attacking people.
The researchers have determined the link after considering factors like the child’s age and sex. They have also considered other possible influence, such as whether the boys and girls are eating sweets or giving fruit drinks on a normal day. In addition, the researchers have examined parenting styles and other social conditions that may be taking place in the home.
Researches are trying to find why young children who drink a lot of soda have behavior problems. An ingredient often found in soft drinks is caffeine, which helps to make people feel energetic. Doctor Suglia suggests that caffeine could cause the 5-year-olds to be more aggressive. Earlier studies of adults have found the highest sugar levels in those who carry weapons (武器) and show signs of negative social behavior.
【小题1】What section of a newspaper is the passage probably taken from?
| A．Scientific Technology | B．Science Fictions |
| C．Social News | D．Health Report |
| A．backward | B．unsocial | C．generous | D．friendly |
| A．age | B．sex | C．games | D．parents |
| A．Mothers were asked to keep a record of how many servings of soft drinks their children drank over a three-month period. |
| B．4 percent of the youngsters have even four or fewer sodas to drink every day. |
| C．Children who drink no soda show fewer aggressive behaviors. |
| D．Children with the highest sugar levels tend to carry weapons and show signs of negative social behavior. |
| A．soft drinks | B．attention problems |
| C．caffeine | D．social conditions |

While there has been public debate about whether running is good for your health for a long time, experts agree that running has more benefits than the costs. Some people are concerned that the pressure on your knees and ankles can be detrimental. While this can be true, there are many things that you can do to reduce your risk of injury.
You should always go to a doctor for advice before you begin any type of exercise program. Then, a good pair of running shoes can be helpful as your feet hit the ground. They will help protect your ankles by providing stability to your feet. So it is good idea to visit a specialty(专业) running shoe store. The staff there can suggest shoes which are ideal for your running style.
In order to learn the proper form, you may get some advice from a friend who has been running for some time, or even join a running club. They can provide good tips as well as some support and encouragement for you.
Lastly, it is important to start out slowly. When it comes to getting in shape and losing weight , short bursts of speed followed by periods of slower movement would be proper. Aim for around 30 minutes of exercise a few days a week. As you get better, you can increase your speed. Always allow your body to rest in between heavy exercise as your muscles need time to bring energy back.
Follow these instructions and your running experience will be a great one!
