In the past, the affairs happening inside one country had little influence on other countries, even the neighboring ones. Therefore, incidents of food safety only affected and spread within one country, one city, one island or one village. However, with globalization, goods and products can almost flow freely between countries, regions, and continents. So the food safety problem is therefore no longer a national or regional issue, but rather a global one．
In 1997, Avian Influenza caused widespread panic in Hong Kong．It is said that the Avian Influenza originated from Shenzhen. Some Hong Kong people blamed the chicken farm staff on the mainland for the outbreak. The staff was accused of not thoroughly checking the health condition of the chicks under their care. It resulted in Hong Kong people's anger towards chicken farm staff in Shenzhen, whose supposed negligence(疏忽)contributed to the later spread of Avian Influenza in Hong Kong．
Worse still, in Germany, people have been warned not to eat cucumbers until tests can identify the source of a deadly E. coli outbreak. The scare has spread across Europe, with 16 people so far having been killed．In many people's minds, European countries have the strictest standards and checking procedures on their food safety. But the E. coli cucumber incident brought home the reality that it was not an effective defense against such an outbreak．
These diverse food safety issues from various parts of the world are enough evidence that food safety problem is not endemic in China. In fact, food safety is not even directly related to the development level of a place, thanks, no doubt, to the connectivity of our age. If we do not maintain our vigilance(警惕), people's confidence in food safety can be destroyed instantly—even in a developed country
小题1:Which of the following is true according to the passage?

Bad teeth can be painful -- and worse. They can even be deadly. Infections (感染) of the gums (牙龈) and the teeth can cause bacteria (细菌) to go into the blood system. Those bacteria can increase the chance of a heart attack and worsen the effects of other diseases. And adults are not the only ones at risk.
For example, in 2007, doctors in the Washington area said a boy died when a tooth infection spread to his brain. They said it might have been prevented had he received the dental care (牙齿保健) he needed. He was twelve years old.
Experts at the National Institutes of Health 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 the growth of bacteria and acid production in the mouth.
But dentists say a baby's gums and early teeth should be cleaned after each feeding. Use a cloth with a little warm water. Do the same if a baby is fed with a bottle. Experts say if you decide to put your baby to sleep with a bottle, only give the child 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 (珐琅质) , the hard surface on teeth, to help prevent holes from forming.

As an English saying goes, “Laughter is the best medicine.” Until recently, few people took the saying seriously. Now however, doctors have begun to look into laughter and the effects it has on the human body. They have found that laughter really can improve people’s health.
Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their heart, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise. It increases blood pressure, makes the heart beat quicker and makes people breathe deeper; it also works several groups of muscles in the face, the stomach, and even the feet. If laughter exercises the body, it must be beneficial.
Other tests have shown that laughter appears to be able to reduce the effect of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programs. The group that tolerated (忍耐) the pain for the longest time was the group which listened to a funny program. The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemical in the brain which diminishes both stress and pain.
As a result of these discoveries, some doctors in the United States now hold laughter clinics, in which they help to improve their patients’ condition by encouraging them to laugh. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.

Your body works 24 hours a day. It’s always building and repairing, feeding and cleansing itself. Its goal is to be ready for your every movement, breath, and thought. The quality of your life depends on how well your body works. And how well your body works depends on how much energy it gets. Energy comes from the food you eat. Food contains nutrients that your body needs for growth and energy.
By eating a balanced diet, your body gets the six important nutrients it needs. Minerals（矿物质） are nutrients that build bones and teeth. Minerals also form red blood cells and other substances. Water aids digestion and waste removal. Carbohydrates（碳水化合物） give your body its main source of energy. Two carbohydrates are sugars from foods such as fruits and vegetables and starches found in rice, potatoes, and bread. Fats help build cell membranes（膜）. Proteins repair and grow body tissues（组织）. Finally, vitamins help your body use carbohydrates, fats, and proteins.
The United States Department of Agriculture（USDA） has created a nutritional food pyramid（金字塔）. It shows the daily number of servings you should eat from five food groups. The food pyramid has four levels. The base of the pyramid is the largest level. It contains the bread, cereal, rice, and pasta group from which you need six to eleven servings. The next level has two food groups: vegetables and fruits. The USDA recommends three to five servings of vegetables and two to four servings of fruit. The third level also has two groups: the milk, yogurt, and cheese group and the meat, poultry, fish, dry beans, eggs, and nuts group. You need two to three servings from each of these groups. The top of the pyramid is the smallest level. It contains fats, oils, and sweets. These foods have few nutrients, so eat them sparingly（有节制地）.

Do you love holidays but hate the increase（增长的） weight that follows? You are not alone.
Holidays are happy days with pleasure and delicious foods. Many people, however, are worried about the weight that comes along with these delicious foods.
With proper planning, though, it is possible to control your weight. The idea is to enjoy the holidays but not to eat too much. You don’t have to turn away from the foods that you enjoy. The following suggestions may be of some help to you.
Do not miss meals. Before you leave home for a feast (宴会), have a small, low-fat snack(小吃). This may help to keep you from getting too excited before delicious foods.
Begin with clear soup and fruit or vegetables. A large glass of water before you eat may help you feel full. Use a small plate; a large plate will encourage you to have more than enough.
Better not have high-fat foods. Dishes that look oily or creamy have much fat in them.
Choose lean meat (瘦肉). Fill your plate with salad and green vegetables.
If you have a sweet tooth, try mints (薄荷) and fruits. They don’t have fat content as cream and chocolate.
Don’t let exercise take a break during the holidays. A 20-minute walk after a meal can help burn off excess (过多的) calories.

A growing number of workers at Google Inc., Facebook Inc. and other employers are trading in their sit-down desks for standing ones, saying they feel more comfortable and energized. They also are motivated by medical reports saying that sitting for too long leads to increased health risks.
A standing desk sits high off the floor so a worker can either stand at it or sit on a high stool to use it. Officials at Palo Alto-based Facebook say a number of employees asked about standing desks after news articles were published about the health risks of sitting all day.
The stories cited medical studies that tied excessive sitting to increased obesity and other health problems because of factors including a drop in physical activity. A 2010 study by the American Cancer Society found that women who sat more than six hours a day were 37% more likely to die prematurely than women who sat for less than three hours, while the early-death rate for men was 18% higher. The American College of Cardiology released a study in January that found increased mortality (死亡率) among people who sat longer at home than those who didn't.
No one seems to compile statistics on the standing-desk trend. But anecdotal reports suggest Silicon Valley is embracing the movement.
Facebook officials say they have seen an upsurge in requests for standing desks to five to eight a week with a total of between 200 and 250 deployed (配置) at the company of more than 2,000 employees. Facebook also is trying out a treadmill station ─ where a worker can walk or run on a treadmill while tapping at a computer.
Google spokesman Jordan Newman said that 'many employees at Google opt for standing desks, and we offer them as part of our wellness program' though he said he didn't know the exact number.
Greg Hoy, 39 years old, asked for a standing desk shortly after joining Facebook seven months ago as a design recruiter. 'I don't get the 3 o'clock slump anymore,' he said. 'I feel active all day long.'

Judging from recent surveys, most experts in sleep behavior agree that there is virtually an epidemic（流行病） of sleepiness in the nation．“I can’t think of a single study that hasn’t found Americans getting less sleep than they ought to,” says Dr．David．Even people who think they are sleeping enough would probably be better off with more rest．
The beginning of our sleep-deficit（lack）crises can be traced back to the invention of the light bulb a century ago．From diary entries and our personal accounts from the 18th and 19th centuries, sleep scientists have reached the conclusion that the average person used to sleep about 9.5 hours a night．“The best sleep habits once were forced on us, when we had nothing to do in the evening down on the farm, and it was dark．” By the 1950s and 1960s, the sleep schedule had been reduced dramatically, to between 7.5 and 8 hours, and most people had to wake to an alarm clock．“People cheat in their sleep, and they don’t even realize they’re doing it,” says Dr．David．“They think they’re okay because they can get by on 6.5 hours, when they really need 7.5, 8 or even more to feel ideally energetic. ”
Perhaps the most merciless robber of sleep, researches say, is the complexity of the day．Whenever pressures from work, family, friends and community increase, many people consider sleep the least expensive item on their programs．“In our society, you’re considered dynamic if you say you need only 5．5 hours’ sleep．If you’ve got to get 8．5 hours, people think you lack drive and ambition．”
To determine the consequences of sleep-deficit, researchers have put subjects through a set of psychological and performance tests requiring them, for instance, to add columns of numbers or recall a passage read to them only minutes earlier．“We’ve found that if you’re in sleep deficit, performance suffers,” says Dr．David．“Short-term memory is weakened, as are abilities to make decisions and to concentrate．”
小题1:What is the main topic of the passage?

A．The history of people’s sleeping patterns．

B．The epidemic of sleepiness in the modern times．

C．Research on the causes and consequences of sleep-deficit．

D．The minimum of our sleeping hours．

小题2:Which of the following is Dr．David’s opinion?

A．People’s metal power suffers if they are lacking in sleep．

B．Some people can remain energetic with only 6．5 hours’ sleep a night．

C．If they get 8．5 hours’ sleep, people will be full of drive and ambition．

D．People who think they are sleeping enough are better off than those who don't．

小题3:People in the 18th and 19th centuries slept about 9．5 hours a night because _______．

A．they had no electricity

B．they knew what was best for their health

C．they were forced by their parents to do so

D．they were not so dynamic and ambitious as modern people are

小题4:The major cause of sleep-deficit of modern people is _______．

A．the endless TV programs in the evenings and the internet

B．the heavy work load of the day

C．the sufficient energy modern people usually have

D．loud noises in the modern cities

小题5:What does the word “subjects” in paragraph 4 mean?

A．Person or thing that is being discussed or described．

B．Branch of knowledge studied in a school．

C．Person or thing being treated in a certain way or being experimented on．

D．Any member of a State apart from the supreme ruler．

A．men’s heart cells	B．women’s ageing process
