单选题Flu does Scratchy throats, stuffy noses and body aches all spell misery, but being able to tell if the cause is a cold or flu may make a difference in how long the misery lasts. The American Lung Association (ALA) has issued new guidelines on combating colds and the flu, and one of the keys is being able to quickly tell the two apart. That's because the prescription drugs available for the flu need to be taken soon after the illness sets in. As for colds, the sooner a person starts taking over-the-counter remedy, the sooner relief will come. The common cold and the flu are both caused by viruses. More than 200 viruses can cause cold symptoms, while the flu is caused by three viruses-flu A, B and C. There is no cure for either illness, but the flu can be prevented by the flu vaccine (疫苗), which is, for most people, the best way to fight the flu, according to the ALA. But if the flu does strike, quick action can help. Although the flu and common cold have many similarities, there are some obvious signs to look for. Cold symptoms such as stuffy nose, runny nose and scratchy throat typically develop gradually, and adults and teens often do not get a fever. On the other hand, fever is one of the characteristic features of the flu for all ages. And in general, flu symptoms including fever and chills, sore throat and body aches come on suddenly and are more severe than cold symptoms. The ALA notes that it may be particularly difficult to tell when infants and preschool age children have the flu. It advises parents to call the doctor if their small children have flu-like symptoms. Both cold and flu symptoms can be eased with over-the-counter medications as well. However, children and teens with a cold or flu should not take aspirin for pain relief because of the risk of Reye syndrome (综合症), a rare but serious condition of the liver and central nervous system. There is, of course, no vaccine for the common cold but frequent hand washing and avoiding close contact with people who have colds can reduce the likelihood of catching one.

单选题 Liver Disease The liver is the second largest organ in your body. The liver performs many jobs in your body. It processes what you eat and drink into energy and nutrients your body can use. The liver also removes harmful substances from your blood. One out of every 10 Americans is affected by liver disease. Liver disease is one of the top 10 causes of death in the United States. There are more than 100 liver diseases. Viruses cause some of them, like hepatitis A, hepatitis B and hepatitis C. Others can be the result of drugs, poisons or drinking too much alcohol. If the liver forms scar tissue because of an illness, it's called cirrhosis. Cancer can affect the liver. You should also inherit a liver disease such as hemochromatosis. Liver disease can manifest in many ways. Characteristic manifestations include jaundice, liver enlargement, portal hypertension and etc. Sometimes the manifestations of liver disease are not obvious. For example, symptoms may include fatigue, a general feeling of illness, loss of appetite, and mild weight loss. However, people may not notice these symptoms, and these symptoms are also typical of many other diseases. Thus, liver disease can easily be overlooked, particularly in its early stages. Hepatitis A vaccination is the best way to prevent HAV (hepatitis A virus). Hepatitis B vaccination is the best way to prevent HBV. Other ways to stop the spread of HBV are: not sharing needles; practicing safe sex; not Sharing razors, toothbrushes, or other personal items; using only clean needles for fattoos and body piercings. There is no vaccine to prevent HCV. The only way to prevent HCV is to avoid direct contact with infected blood. Eating a healthy diet and exercising regularly help the liver to work well. Limit the amount of alcohol you drink. When medicines are taken incorrectly, the liver can be harmed. So follow dosing instructions and talk to a doctor or pharmacist about the medicines you are taking. Mixing alcohol and medicines can harm your liver, even if they are not taken at the same time. Toxins can injure liver cells. So limit direct contact with toxins from cleaning and aerosol products, insecticides, chemicals, and additives in cigarettes. Do not smoke.

单选题Step Back in Time Do you know that we live a lot longer now than the people who were born before us? One hundred years ago the average woman lived to be 45. But now, she can live until at least 80. One of the main reasons for people living longer is that we know how to look after ourselves better. We know which foods are good for us and what we have to eat to make sure our bodies get all the healthy things they need. We know why we sometimes get ill and what to do to get better again. And we know how important it is to do lots of exercise to keep our hearts beating healthily. But in order that we don't slip back into bad habits, let's have a look at what life was like 100 years ago. Families had between 15 and 20 children, although many babies didn't live long. Children suffered from lots of diseases, especially rickets (佝偻病) and scurvy (坏血病), which are both caused by bad diets. This is because many families were very poor and not able to feed their children well. Really poor families who lived in crowded cities like London and Manchester often slept standing up, bending over a piece of string, because there was no room for them to lie down. People didn't have ridges until the 1920s. They kept fresh food cold by storing it on windowsills (窗台板), blocks of ice, or even burying it in the garden. Some children had to start work at the age of seven or eight to earn money for their parents. If you had lived 100 years ago, you might well be selling matchsticks (火柴杆) (a job done by many children) or working with your dad by now.

Not only do babies get to doze their days away, but they've also mastered the fine art of learning in their sleep. By the time babies are a year old they can recognize a lot of sounds and even simple words. Marie Cheour at the University of Turku in Finland suspected that they might progress this fast be cause they learn language while they sleep as well as when they are awake. To test the theory, Cheour and their colleagues studied 45 newborn babies in the first days of their lives. They exposed all the infants to an hour of Finnish vowel soundsone that sounds like "oo", another like "ee" and a third boundary vowel peculiar to Finnish and similar languages that sounds like something in between. EEG recording of the infants brains before and after the session showed that the newborns could not distinguish the sounds. Fifteen of the babies then went back with their mothers, while the rest were split into two sleep study groups. One group was exposed throughout their night-time sleeping hours to the same three vowels, while the others listened to the other, easier-to-distinguish vowel sounds. When tested in the morning, and again in the evening, the babies who'd heard the tricky boundary vowels all night showed brainwave activity indicating that they could now recognize this sound. They could identify the sound even when its pitch was changed, while none of the other babies could pick up the boundary vowel at all. Cheour doesn't know how babies accomplish this nighttime learning, but she suspects that the special ability might indicate that unlike adults, babies don't "turn off" their cerebral cortex while they sleep. The skill probably fades in the course of the first years of life, she adds-so forget the idea that you can pick up the tricky French vowels as an adult just by slipping a language tape under your pillow. But while it may not help grown-ups, Cheour is hoping to use the sleeping hours to give re medial help to babies who are genetically at risk of language disorders.

单选题 Thanksgiving Day The American Thanksgiving Day celebration goes back to 1621. In that year, a special dinner was prepared in Plymouth, Massachusetts. The people who had settled there had left England because they were forbidden to keep their religious belief. They came to the new land and faced difficulties in sailing across the ocean. The ship which carried them was called "the Mayflower". The North Atlantic was hard to travel. There were bad storms and huge waves. With the help of the Indians, they learned to live in the new land. These Puritans, as they were called, had much to be thankful for. They could enjoy religious freedom. They learned how to grow their crops in accordance with the climate and soil. Now when they selected the fourth Thursday of November for their Thanksgiving celebration, they invited their neighbors, the Indians, to join them in dinner. They also wanted to pray God for the new life. They recalled the group of 102 men, women and children who left England. They remembered those who did not live to see the shores of Massachusetts. They thought of the 65 day's journey which tested their strength.
