A new study has found evidence of aggressive (攻擊性的) 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“For the children who consume four or more soft drinks per day, we see more withdrawn behaviors, which make them hard to get along well with others.”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.

55% of deaths caused by road accidents occur in the first few minutes after a crash. Up to 85% of these deaths could be prevented if first aid were given. The first person on the scene of a road accident will almost certainly be another road user. So as a driver your knowledge of first aid could make a real difference to someone in the event of a road accident.
Assess conditions
·Remain calm. Judge the scene and seriousness of the collision.
·Determine what has happened, how many people and vehicles are involved and the exact location.
·Determine how many casualties(傷亡人數(shù)) there are, what is the severity of the injuries, whether anyone is trapped, and whether there is a danger of fire.
Make safe
·Make sure you stay safe and keep off the road. If you need to stop or warn approaching cars, signal to them from the pavement. Wear reflective clothing, use warning triangles, flashing lights and warning lights. Don’t smoke.
·If you are in a car and you come across an accident, first park safely and turn off the engine before you get out to help. Use a triangle warning danger if necessary.
·Consider the safety of others. Don’t move the vehicles, look out for dangers — leaking fuel, chemicals, broken glass or dropping loads — guide uninjured passengers to a place of safety.
Call for help
Dial 999 (or 112) for the emergency services. If there is no phone nearby, send two people in opposite directions to seek help.
Do this as soon as you can or get someone else to do it while you deal with an injured person. You will need to tell the emergency services:
·where you are
·what has happened (describe the accident)
·how many people are injured
·whether they are breathing or bleeding.
The operator will talk you through what to do while you wait for an ambulance to arrive.
Apply emergency first aid
·Remain calm. Reassure the victims.
·Do not allow smoking or offer food or drink to casualties as this could hamper urgent medical treatment.
【小題1】The passage mainly tells us ______.

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 (動(dòng)態(tài)) 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.
【小題1】What is the passage mainly about?
A.Teens’ sleep is linked to their relationship with people around them. |
B.Lack of adequate sleep puts teens at risk of many bad consequences. |
C.Modern technology has something to do with teens’ sleep problems. |
D.It is necessary for teens to join in sports and positive social activities. |
A.Teens who feel like talking with their parents. |
B.Teens who have friends sharing their dreams. |
C.Teens who feel contented about themselves. |
D.Teens who lack a sense of security at school. |
A.a(chǎn) comparison | B.a(chǎn)n introduction | C.a(chǎn) conclusion | D.a(chǎn)n addition |
A.continue their broken marriage | B.a(chǎn)llow children to decide when to sleep |

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. |
C.To take action to wash hands. | D.To wash hands often. |
A.a(chǎn)--c--b--e--d | B.e--d--a--b—c |
C.a(chǎn)--c--b--d--e | D.e--b--d--a--c |
A.It gives people a longer handwashing time. |

Air pollution is a leading cause of cancer and classified among Group 1,or top, human carcinogens (致癌物質(zhì)), 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.
【小題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. |

Imagine you are doing this reading in this text on the computer; what else are you doing? Maybe you’re eating a sandwich or drinking a cup of Starbucks. Should you eat while reading?
There aren’t many believable numbers, but we do know the number of people who eat while sitting in front of some type of screen is growing. A recent study found that 33 percent of families always have the TV on during meal times and another 27 percent people have it on at least half the time. Another 10 percent may be texting, emailing or talking on a cell phone while eating.
Any type of these behaviors is bad, considering the following evidence:
A Canadian study found that children who watch more than three hours of cartoons a day are 50 percent more likely to be fat than children who watch fewer than two hours. The researchers concluded that more than 60 percent of overweight incidents can be connected with screen watching too much.
A three-week study found that adults who usually play with smartphones less burned 119 more calories per day.
One Chicago researcher found that people eat more potato chips while reading online than when they have the laptop turned off.
There has been very little investigation(調(diào)查) into eating with your eyes staring at a screen or reading a book, but it is likely that his mindless eating is related to weight gain. Simply speaking, your brain has no idea what is going on with your mouth because it is occupied by other things. You don’t notice how full your stomach is, and you often don’t even notice the taste or the act of chewing and swallowing, as a result of which, developing an adapted dietary habit is a must.

A.stories and explanations |
B.examples and investigations |
C.a(chǎn)n argument and evidence |
D.facts and descriptions |
A.Being focused while eating is a good way to have a good figure. |
B.Adults’ weight is not affected by their eating habits. |
C.There exist many investigations into eating while reading. |

Studies show that children who eat breakfast do better in school. It doesn’t take much further thought to know that adults will feel better and do better at work as well. Whether you work at home, on the farm, at the office, at school, or on the road, it is not a good idea to have no breakfast.
If we have no breakfast, we are likely to become tired when our brains and bodies run low on fuel (食物). By mid-morning, a lot of us grab a cup of coffee or eat a sugary candy bar to wake up again. This might work for a few minutes, but by lunch time we are hungry. Eating a good breakfast sets the tone for the rest of the day.
Having no breakfast is a popular way to lose weight, but not a smart one. Many people believe that they will lose weight if they have no meals, but that just isn’t true; the body expects to be refueled a few times a day, starting with a healthy breakfast. Eating breakfast is good for losing weight. In fact, people who eat breakfast are more likely to keep a healthy weight.
A healthy breakfast should have some protein (蛋白質(zhì)) and some fiber (纖維). Protein can come from low fat meats, eggs, or beans. Fiber can be found in whole grains, vegetables and fruits. A good example of a healthy breakfast might be something simple like a hard boiled egg, an orange, and a bowl of whole grain cereal with low fat milk. Stay away from sugary foods and white bread because they are digested (消化) quickly and will leave you hungry and tired in several hours. Protein and fiber will keep you feeling full until lunch time.
【小題1】The first paragraph mainly tells us that ______.
A.it is necessary to have a good breakfast every day |
B.many adults are too busy to have breakfast every day |
C.many adults go to work without having breakfast |
D.many children go to school without breakfast |
A.we need to have a cup of coffee | B.we don’t have a good breakfast |
C.our brains don’t work any longer | D.we don’t have enough sleep at night |
A.Having a good breakfast can help you to finish your work. |
B.Eating a good breakfast is enough for the whole day. |
C.Breakfast is really the most important meal in a day. |
D.You will be happier if you have a good breakfast. |
A.it is healthy only to have beans and eggs for your breakfast |
B.you mustn’t have meat for your breakfast |
C.you should eat sugary foods if you feel hungry |
D.you should eat something which has protein and fiber for breakfast |

Malaria, the world's most widespread parasitic(寄生蟲(chóng)引起的) disease, kills as many as three million people every year—almost all of whom are under five, very poor, and African. In most years, more than five hundred million cases of illness result from the disease, although exact numbers are difficult to assess because many people don't (or can't) seek care. It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment, and what they often get no longer works. In countries like Tanzania, Mozambique, and the Gambia, no family, village, hospital, or workplace can remain unaffected for long.
Malaria starts suddenly, with violent chills, which are soon followed by an intense fever and, often, headaches. As the parasites multiply, they take over the entire body. Malaria parasites live by eating the red blood cells they infect. They can also attach themselves to blood vessels in the brain. If it doesn't kill you, malaria can happen again and again for years. The disease passed on to humans by female mosquitoes infected with one of four species of parasite. Together, the mosquito and the parasite are the most deadly couple in the history of the earth—and one of the most successful. Malaria has five thousand genes, and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control. Studies show that mosquitoes are passing on the virus more frequently, and there are more outbreaks in cities with large populations. Some of the disease's spread is due to global warming.
For decades, the first-choice treatment for malaria parasites in Africa has been chloroquine, a chemical which is very cheap and easy to make. Unfortunately, in most parts of the world, malaria parasites have become resistant to it. Successful alternatives that help prevent resistance are already available, but they have been in short supply and are very expensive. If these drugs should fail, nobody knows what would come next.
【小題1】According to paragraph 1, many people don't seek care because___.
A.they can remain unaffected for long |
B.it is unusual to seek care |
C.they are too poor |
D.there are too many people suffering from the disease |
A.have to kill female mosquitoes |
B.have ability to defend parasites |
C.have their red blood cells infected |
D.have sudden fever, followed by chills |
A.Its outbreaks in cities with large populations. |
B.Its ability to pass on the virus frequently. |
C.Its resistance to global warming. |
D.Its ability to defend itself and resist new drugs. |
A.no drugs have been found to treat the disease |
B.the alternative treatment is not easily available to most people |
C.malaria has developed its ability to resist parasites |
D.nobody knows what will be the drug to treat the disease |
