Tiredness, coughing, a runny nose and a sore throat—among all sicknesses there is probably none more common than the flu (流感), which we all get now and then. However, bird flu is a completely different story.
In 2003, the H5N1 bird flu swept across 15 countries, including China, with sufferers reporting chest pain, difficulty breathing, fever and severe coughing. More than 600 people were infected, and about 60 percent died. Now, another type of bird flu hit Shanghai and three neighboring provinces, and this time the virus is called H7N9. By the afternoon of April 11, the new virus had taken nine lives out of 35 infected, according to Xinhua News Agency.
The “H” and “N” in the virus’ name refer to two kinds of proteins (蛋白质) on the surface of the virus. Any change of the numbers of the two proteins indicates a new mutation(变异). Most of the mutations only affect birds, such as chickens and pigeons, and don’t normally spread to humans. But once they do, the results can be disastrous.
“Any time an animal influenza virus crosses to humans, it is a cause for concern, ” Malik Peiris, virologist (病毒学家) at the University of Hong Kong, told Nature magazine. Take the SARS epidemic (传染病) in 2003 as an example. The virus behind the disease is thought to have jumped to humans from animals. The virus was a complete “stranger” to human bodies, which hadn’t developed an immunity (免疫力) against it.
But there is something more about the new H7N9 bird flu. Unlike the H5N1 bird flu, which causes severe sickness in birds, the H7N9 has been evolving under the radar(悄悄地) since it travels between birds without causing noticeable illness. That makes it difficult to keep track of the disease.
The good news is that there’s so far no sign that the virus is spreading from person to person. But since there is no vaccine (疫苗) for the disease yet, the World Health Organization recommends that you wash your hands after meeting with sick people and before and after you eat or prepare food, and they also suggest avoiding contact with birds or their eggs.

Do you have a sore throat, a running nose and a headache? Do you keep coughing and sneezing? If you do, the chances are that you have a cold or perhaps flu---but which one? Although both colds and flu are caused by viruses, they are very different illnesses.
Colds, which usually last about a week, affect the nose most. They commonly cause a running nose and sneezing. Sometimes, they cause a headache, a cough and slightly aching muscles.
Flu is a much more serious illness and is caused by different groups of viruses. People with flu usually get all the symptoms(症状) described above. However, they also get a high fever, a dry cough and much worse aching. Fever is one of the characteristic symptoms of the flu for all ages. The symptoms also last much longer. Sometimes they don’t disappear for at least two weeks.
Flu can be a deadly disease. The elderly(年长的), who are weaker and less healthy than most younger people, can die from flu. This is one reason why old people are advised to have a flu injection(预防针) before the start of winter when flu is most common. This injection is inexpensive and definitely(明显地)worth it.
If you have a cold or flu, you must always deal with used tissues(手巾纸) carefully. Don’t leave dirty tissues on your desk or on the floor. Someone else has to pick these up and viruses could be passed on. And finally, remember to cover your nose and mouth when you sneeze! You don’t want to see the small drops of liquids blown(喷) out of your nose and mouth when you sneeze, do you? Disgusting(令人作呕), eh? Now you can understand why it’s a good idea to cover your nose and mouth when you sneeze!

高二英语阅读理解简单题查看答案及解析
Fever, coughing, sore throat… most of us at one time or another have had these symptoms. What causes them? In fact, many diseases are caused by viruses, including some deadly ones like AIDS, SARS and COVID-19, also known as the novel coronavirus pneumonia, outbreak in China.
What are viruses? How can viruses cause so much trouble? Viruses are very small particles (颗粒) which are about one millionth of an inch long. Unlike human cells or bacteria, viruses aren’t living organisms- they can't reproduce on their own. Instead, they invade the cells of living organisms to reproduce, spread and take over.
Virus can infect every living thing- from plants and animal down to the smallest bacteria. For this reason, they are always a potential danger to humans. Viruses lie around our environment all of the time, waiting for a host cell to come along. They can enter our bodies by the nose, mouth, eyes or breaks in the skin. Once inside, they try to find a host cell to infect. For example, HIV, which causes AIDS, attacks the T-cells of the immune system.
But the basic question is, where did viruses first come from? Until now, no clear explanation for their origin exists. "Tracing the origins of viruses is difficult, "Ed Rybicki, a scientist at the university of Cape Town in South Africa, told Scientific American, "because viruses don' t leave fossils and because of the tricks they use to make copies of themselves within the cells they've invaded.”
However, there are three main theories to explain the origin of viruses. First, viruses started as dependent organisms, then became parasites(寄生者)。Second, viruses evolved from pieces of DNA or RNA that "escaped" .from larger organisms. Third, viruses co-evolved with their host cells, which means they existed alongside these cells.
For the time being, these are only theories. The technology and evidence we have today cannot be used to test these theories and identify the most reasonable explanation. Continuing studies may provide us with clearer answers or future studies may find that the answer is even more mysterious than it now appears.
1.What can we learn about viruses from the text?
A.Viruses are really small living organisms.
B.Viruses have nothing to do with the common cold.
C.Viruses can't reproduce unless they find a host cell.
D.Viruses enter our bodies mainly through our mouths, noses and hair.
2.Why are viruses always a potential danger to humans?
A.TH most infect all the living things around us.
B.They prefer evolving with the cells in our body.
C.They can copy human's DNA and evolve successfully.
D.They can enter our body far more easily than other living things.
3.Which of the following might explain the origin of viruses?
A.They evolved from the DNA of animals.
B.They evolved along with their host cells.
C.They evolved from the fossils of large organisms.
D.They evolved from parasites to independent organisms.
4.What can we conclude from the last paragraph?
A.The author is confident about future virus research.
B.Viruses will become more like bacteria as they evolve.
C.Viruses live longer in human host cells than in animals.
D.It may take a long time to understand the origin of viruses.

The Value of Tears
Tears can ruin make-up, bring conversation to a stop, and give you a runny nose. Tears leave you embarrassed and without energy. Still, crying is a fact of life, and your tears are very useful. Even when you’re not crying, they make a film over the eye’s surface.1.
When tears fall, they reduce stress. But we tend to fight them for all sorts of reasons. “People worry about showing their emotions, afraid that once they lose control they’ll never get it back.”2. After we cry, the feelings that caused the tears often disappear.
Sometimes people become much stressed and can’t cry. Whatever emotion they are feeling—shock, anger, fear, or sadness—is being held back.
But everyone has the need to cry. Psychologist Vera Diamond explains that her treatment often consists of giving people permission to cry. 3.Patients practice crying just to become used to expressing emotions. She suggests safe, private places to cry, like under the bedcovers or in the car. Crying is a way of reducing tension, but people don’t like it when others cry because it makes them tense.4. And they’ll do just about anything to make you stop.
In certain situations, such as at work, tears are not appropriate. It’s good not to cry during a tense business discussion.5.You should also act out the whole situation again and be as noisy and angry as you like. It will help you feel better. “And,” she adds, “Once your tears have taken away the stress, you can begin to think calmly of ways to deal with the problem.”
Tears are a sign of our ability to feel. If you find yourself near someone crying, deal with it. And never be afraid to cry yourself.
A.They too may be holding back a need to cry.
B.They cry for different reasons.
C.She gives crying exercises.
D.It contains a chemical against infection.
E.The fact is that no emotion lasts forever.
F.It forms in response to the stress on the surface of the eye.
G.But once you’re safely behind closed doors, don’t just cry.

The most common disease in the world is the cold. It often starts with a sore throat(咽部疼痛). You sneeze (打喷嚏) and your nose runs. You usually have a headache, too. Often you have a cough later. It's not a serious disease, but you can feel quite bad.
There isn't a cure (良药 ) for a cold, but you can take medicines to make you feel better. For example, you can take aspirin (阿司匹林) to get rid of your headache. It is good to rest, and to drink a lot of water, too. A doctor once told me, "With the right medicine, a cold will last for seven days. With no medicine, it will go on for a whole week!"
Where does our medicine come from? A long time ago, people understood that some plants made them feel better. They ate the leaves, the roots , the fruit or the seeds of plants. For example, the juice of lemons (柠檬) makes a sore throat feel better. In modern times, scientists have looked at these plants, and found out which chemicals (化学药品) are in them. Many of our medicines today are made from those chemicals. There are some diseases that we can't cure yet. And nobody has found a cure for old age. But because of modern medicines, the average (平均的) person now lives longer than their grandparents.

A person's nose is important for breathing and smelling. The nose is also used in many popular expressions. Some people are able to "lead other people by the nose". For example, if a wife "leads her husband by the nose", she makes him do whatever she wants him to do. Some people are said to be "hard-nosed". They will not change their opinions or positions on anything. If someone is "hard-nosed", chances are that he will never "pay through the nose", or pay too much money, for an object or service.
It is always helpful when people "keep their noses out of other people's business"—they do not interfere. The opposite of this is someone who "noses around all the time". This kind of person is interested in other people's private matters. He is considered "nosey". Someone who "keeps his nose to the grindstone "works very hard. This can help a worker "keep his nose clean" or stay out of trouble.
One unusual expression is "it is no skin off my nose". This means that a situation does not affect or concern me. We also say that sometimes a person "cuts off his nose to spite his face". That is, he makes a situation worse for himself by doing something foolish because he is angry. More problems can develop if a person "looks down his nose" at someone or something. The person acts like something is unimportant or worthless. This person might also "turn his nose up" at something that he considers not good enough. This person thinks he is better than everyone else. He is "with his nose in the air".
In school, some students "thumb their noses" at their teacher—they refuse to obey orders or do any work. Maybe these students do not know the correct answers. My mother always told me, if you study hard, the answers should be "right under your nose" or easily seen.
1.Which of the following can best describe a "hard-nosed" person?
A. Stubborn. B. Wise.
C. Jealous D. Generous.
2.A person is not welcome if he __________.
A. "keeps his nose clean"
B. "noses around all the time"
C. "keeps his nose to the grindstone"
D. "keeps his nose out of other peoples business"
3.The expression "turn one's nose up" is similar to__________.
A. "it is no skin off one's nose"
B. "look down one's nose"
C. "with one' s nose in the air"
D. "thumb one's nose"

It’s 2009. You feel sick, so you go to the doctor. She checks your fever, looks at your throat, and asks what you’ve been thinking about lately. When you leave,she gives you some medicine, but also a list of thinking skills that you are supposed to practice daily. She says that the way you think is causing some of your illness.
Doctors and other scientists who study the human mind and try to explain why people behave in the way that do, called psychologists, are starting to believe it. You know that your brain is connected to every part of your body through your nervous system(神经系统). Now scientists have proved that how you think and feel can have an influence on the health of your body.
Stress(压力,紧张) is caused whenever there is a problem or a change in your life. Of course, everybody has stress more or less; nobody’s life is perfect. In fact, stress is necessary. Without stress, we would never learn anything or grow or change. We would probably be bored to death. But too much stress can hurt you. It can weaken your body’s protection so that you are more likely to catch diseases. It can even make you more likely to have an accident.
When you feel stress, your brain sends a message to your body to produce a chemical called adrenaline(肾上腺素). Adrenaline speeds up your breathing and your heartbeat. Today you have a different kind of stress. Problems like endless homework or troubles with your family are the kind of things you can’t fight or run away from, so you don’t use up all that adrenaline. It just stays bottled up inside you, and that’s what can do something bad to you.
What can you do about stress? First, you can try to find ways to change things so you aren’t under so much stress. You can set up a plan to finish homework or go to a doctor or a psychologist to try to work things out with your family or your friends. But sometimes you can’t change a stressful situation. Sometimes you don’t even want to. A big change might be a good change, but it will still be stressful.
The link(关联) between your body and brain works in two ways. Your body can help your mind deal with stress. If you are under stress, you need to take especially good care of your body. It’s important to get enough sleep and eat nutritious meals. Some people take a vitamin-mineral pill every day. Another thing that you can do is daily exercise. If you go walking or do aerobic(需氧的) dancing or work out at the gym, you give your body a chance to burn up some of that adrenaline. Of course, a person who isn’t used to much physical activity should start slowly. Anyone with a continuing physical problem should check with a doctor before staring any exercise programs.
1. A psychologist is a person who may help you with your ______.
A. illness and abilities B. thoughts and behaviour
C. mind and nervous system D. physical activity and daily exercise
2. Which of the following is TRUE according to the passage?
A. You shouldn’t go to the gym if you are under stress.
B. One can do his homework to burn up adrenaline.
C. Diseases and accidents are caused by stress.
D. Everyone needs stress to improve himself.
3. From the last sentence of Paragraph 5 we can infer that ________.
A. it’s difficult to change a stressful situation
B. it’s not stressful when a good change takes place
C. a big change will cause another stressful situation
D. a stressful situation can’t be changed without any effort
4. What is probably the best title for this passage?
A. The body-Brain Link B. The Causes of Stress
C. The Advice on Health D. The Nervous System
