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(流感), 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, 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.
　
小题1: According to the author, knowing the cause of the misery will help ________.

A．A stuffy nose.	B．A high temperature.
C．A sore throat.	D．A dry cough.

小题5: If children have flu-like symptoms, their parents _______________.

A．are advised not to give them aspirin

C．are encouraged to take them to hospital for vaccination

D．should prevent them from mixing with people running a fever

We all have ideas about what kinds of foods are good to eat. We also have ideas about what kinds of foods are bad to eat. As a result, people from one culture often think the foods that people from another culture eat are nauseating(令人作呕的).When the famous boxer Muhammad Ali visited Africa, for example, one member of his group became quite sick when he saw someone pick up a butterfly and eat it. Many people would find it disgusting to eat rats, but there are forty-two different cultures whose people regard rats as appropriate food.
Food likes and dislikes do not always seem related to nutrition. For example, broccoli is first on a list of the most nutritious common vegetables, but it is twenty-first on a list of vegetables that Americans like most to eat. Tomatoes are sixteenth on the list of most nutritious vegetables, but they are first on the list of vegetables that Americans like most to eat.
But dislike is not the only reason why some cultures will not eat a certain food. In some cultures, certain foods are taboo. Some foods are taboo in certain religions, but there are also other food taboos that are not connected to a religion. We do not usually think about why certain things are taboo in our culture. We may not even know why they are taboo. Anthropologists(人类学家) try to discover the hidden reasons for taboos.
Anthropologists believe that most food likes and dislikes are a result of the ways of life of different people. Some people live in areas where there are both large animals and many insects. It is difficult for these people to kill large animals, and it requires a lot of energy. It is easier for them to use insects for food because it is not difficult to catch insects and it does not require a lot of energy. Nomadic(游牧的) people who move around will not want to keep pigs for food. People will not eat pets such as dogs. Americans eat a lot of beef because there is plenty of land for raising cattle and the me

at can be shipped cheaply for long distances by railroads.
小题1: What’s the main topic of this passage?

A．Food and religion.	B．Food and culture.
C．Nutrition of different foods.	D．Different ways of life.

小题2:Which of the following statements is TRUE about food likes and dislikes?

A．They are seldom related to nutrition.

B．They are mostly associated with people’s taste.

C．They are mostly connected with people’s life styles.

D．They are usually related to cultures or religions.

小题3:The underlined word “taboo” (Line 3, Para. 3) refers to _____.

A．something undiscovered	B．certain religions
C．something forbidden	D．certain foods

小题4:What can we infer from the passage?

A．It is believed that brcoccoli is more nutritious than tomatoes.

B．Americans prefer tomatoes to beef.

C．People in Inner Mongolia would probably like to keep pigs for food.

D．The famous boxer Muhamm Ali would like to eat rat rather than butterfly.

小题5:Why do Americans prefer to eat beef?

A．Because beef provides a lot of energy people require.

B．Because beef is on the list of the most nutritious foods.

C．Because they have the ideal condition to keep and ship cattle.

D．Because cattle are large animals.

Alzheimer's disease affects millions of people around the world. American researchers say the disease will affect more than one hundred million people worldwide by the year twenty fifty. That would be four times the current number. Researchers and doctors have been studying Alzheimer's patients for a century. Yet the cause and cure for the mental sickness are still unknown. However, some researchers have made important steps towards understanding it.
Several early signs of the disease involve memory and thought processes. At first, patients have trouble remembering little things. Later, they have trouble remembering more important things, such as the names of their children.
There are also some physical tests that might show who is at risk of developing Alzheimer's disease. The tests look for proteins in brain and spinal cord fluid. The proteins appear to be found only in people with the disease. The protein tests correctly identify the presence of the disease in about ninety percent of patients.
Now, a much simpler physical test to predict Alzheimer's risk has been developed. Researchers found that trouble with the sense of smell can be one of the first signs of Alzheimer's. Using this information, they developed a test in which people were asked to identify twelve familiar smells. These smells included cinnamon, black pepper, chocolate, paint thinner, and smoke.
The study continued for five years. During this period, the same people were asked to take several tests measuring their memory and thought abilities. Fifty percent of those who could not identify at least four of the smells in the first test had trouble with their memory and thinking in the next five years.
Another study has shown a possible way to reduce a person's chances of developing Alzheimer's disease in old age. Researchers in Chicago found that people who use their brains more often are less likely to develop Alzheimer's disease. Those who read a newspaper, or play chess or word games are about three times less likely to develop the condition.
Researchers say they still do not know what causes Alzheimer's disease. But they say these findings might help prevent the disease in the future.

Faces show emotions. Psychology; computer science, and engineering researchers are joining forces to teach machines to read expressions. If they succeed, your computer may one day "read" your mood and cooperate. Machines equipped with emotional skills could also be used in teaching , robotics, gaming, security, and for psychological diagnoses(诊断).
"Mind Reader", a system developed by Rosalind Picard at the Massachusetts Institute of Technology in the US, uses input from a video camera to do real-time analysis of facial expressions. It reports on whether you seem "interested" or “agreeable” or if you're "confused".
The system can help people detect others' emotions. Picard says this means we could teach a machine to be as sensitive as a human. In fact, a machine can be even smarter: than people since it can tell if a person is lying or just "performing" by analyzing one's facial movements. Jeffrey Cohn, a psychologist at the University of Pittsburgh, uses the Facial Action Coding System to detect human emotions. "The face is always visible," Cohn says, "People communicate a lot about feelings and thoughts through facial expression."
Cohn studied a videotape of criminal who professed to be sad about the murder of several family members and tried to pin the blame on some one else． But Cohn saw no real sadness in the woman's face. Sadness is a combination of facial action units that are difficult to do voluntarily. This means, even though your mouth lies, your face doesn't, and the machine will know it all.
1．People can know a person's emotions from his _____.
A．body movement             B．facial expressions
C．psychological reactions D．mood and attitude

A．the technology still needs improvement.
B．people can do everything with the new machine .
C．face reading technology is nothing new.
D．face reading technology will be widely used in the future.

A super drug that could remove Alzheimer’s (老年痴呆症)，heart disease and diabetes (糖尿病) and help people live to 100 is being developed by scientists. Their research is based on the identification of three genes that help prolong lives and prevent diseases which occur in old age. Medically controlling the proteins made by the “ longevity genes” will allow millions to live longer, predicts Dr Nir Barzilai.
Those whose DNA strongly features the three genes are 80 percent less likely to develop Alzheimer’s. The genes also fight against the deadly impact of smoking, poor diet, obesity and lack of exercise.
Already, several laboratories are working on a pill to imitate the benefits of the genes and Dr Barzilai thinks it could be tested within three years. The pill could remove some diseases that damage old age. “ The advantage of finding a gene that involves longevity is that we can develop a drug that will imitate exactly what this gene is doing,” he said.
Of the three longevity genes, two genes increase the production of so-called good cholesterol(胆固醇), which reduces the risk of heart disease. The third prevents diabetes. They were discovered by Dr Barzilai’s team while studying the DNA of 500 Ashkenazi Jews with an average age of 100. The chances of living that long are one in 10,000 but the group, which shared relatively few common ancestors, was 20 times more likely to hit the entury. Dr Barzilai said: “ 30 percent of them were obese or overweight and 30 percent smoked two acks of cigarettes a day for more than 40 years, however they can live to 100.”
But Andrew Ketteringham of the Alzheimer’s Society said: “Alzheimer’s disease, a most common disease, is likely to be caused by a combination of genetic disosition(遗传倾向), lifestyles and life events. Many genes are probably involved.
小题1:Some people are able to live to 100 years because of ______.

A．a magical medicine

B．three special genes

C．good living habits

D．longevity proteins

小题2:Why does the discovery of the longevity genes mean a lot?

A．Because it can bring great benefits to scientific labs.

B．Because it can help people change their unhealthy genes

C．Because it helps produce a drug that can make people live longer.

D．Because it will help scientists build up a new branch of biology.

小题3: From Paragraph 4 we can infer that ________.

A．longevity genes can create good cholesterol.

B．the volunteers share some common ancestors

C．bad habits are likely to have no effect on the volunteers

D．longevity genes protect the volunteers against bad habits

小题4:What is Andrew Ketteringham’s attitude toward the study?

阅读下列短文，从每题题所给的四个选项（A、B、C、D和E）中选出最佳选项。
Sitting too much is now listed with smoking and junk food as a bad habit that increases your risk of heart disease.
New Australian research shows that half-an-hour in the gym will not make up for the waist-expanding damage caused by spending the rest of the day sitting.
But the good news is that doing chores in the house or gently walking around the office while on the phone might be enough to keep you fit.
The study joins the growing body of evidence suggesting too much sitting might undo the benefits of exercise.
The study measured the intensity of physical activities in 168 subjects over seven days. It found that, regardless of how much exercise they did or their total sitting time, those who took more breaks from sitting had lower risk of thick waists and lower levels of blood lipids(脂肪).
“Higher levels of blood lipids have been linked to a heightened risk of heart disease,” principal researcher Genevieve Healy of the University of Queensland said. “What the study shows is that there are benefits in just getting up regularly and interrupting your sitting time.”
Researchers behind the Stand Up Australia project have written to the Rudd Government requesting $3.5 million for a two-year study into the impact of long sitting time on health and productivity of workers. The study would also develop and test strategies for reducing sitting time on the job.
The latest s

tudy builds on work that is shifting the health promotion focus from purposeful exercise, such as running, to lower intensity activities throughout the day.
The Australian research has been hacked up by US studies.
“To hold a body that weighs 77 kilograms upright takes a fair amount of energy from muscles,” said Professor Marc Hamilton from the University of Missouri. “There is a large amount of energy associated with standing every day that cannot easily be replaced by 30 to 60 minutes in the gym.”
56. What’s the aim of the Stand Up Australia project?
A. To study the factors influencing productivity of workers.
B. To study the reasons for the longer sitting time at work.
C. To develop and test strategies for reducing sitting time in the office.
D. To develop and test strategies for reducing working time.
57. The purpose of the last paragraph is to .
A. provide a scientific basis for the benefits of standing up
B. Compare the effect of standing with exercising in the gym
C. report the new research findings of professor Marc Hamilton
D. figure out the amount of energy associated with daily standing
58. What’s the best title for the text?
A. Exercise in the Gym Is Out.
B. Your Office Chair Is Killing You.
C. A Cause of Heart Disease.
D. Good News for Workers.

It is now commonly known that AIDS is a deadly disease. It does great damage to human beings’ immune system, weakening resistance to disease and leading to death due to utter weakness. To this day, there are no existing drugs that can kill AIDS virus. It is a deadly battle between science and AIDS.
This is only one side of the story. Although it can not be cured, AIDS is preventable. For those who have not caught the disease, the knowledge of preventive measures seems to be the most powerful weapon at hand.
Since the discovery of the first AIDS patient in 1985, the number of HIV carriers is on an alarming rise in China and statistics show that young people are the more likely victims of AIDS. Nationwide there are 214 million people between the ages of 13 and 22, most of whom are students. If no measures are taken to protect these young people, it is almost certain that the threat of AIDS will be very real to them. There has been a great deal of misinformation concerning the transmission of AIDS.
One of the most misleading myths is that AIDS can be transmitted by casual physical contact such as kissing, shaking hands or sharing food container. Surveys and investigations conducted in some universities and colleges show that half of those people questioned are not clear about how AIDS is transmitted, not to mention how it is prevented.
This is the driving force behind the State Education Department’s decision to spread AIDS awareness information among college students and later to high school students and primary school students.
69．Why does the passage say that AIDS is a deadly disease?
A．Because it destroys the immune system of the human body.
B．Because the AIDS patients cannot resist the disease and will die.
C．Because the doctors now find no medicine to cure AIDS.
D．All of the above.
70．By writing “This is only one side of the story”, the author suggests tha

t_____.
A．although we can’t cure AIDS, we can manage to prevent it.
B．AIDS is very dangerous, but we should not be scared of it.
C．AIDS is not curable, but doctors should not give up fighting against it.
D．although the doctors cannot cure the disease, they can help improve the patients’ health.
71．What can be concluded from the surveys and investigations mentioned in the passage?
A．No college students know how people become AIDS victims.
B．5

0 percent of college students do not know how to prevent AIDS.
C．Many college students are not aware how people become AIDS victims.
D．Many college students did not mention AIDS prevention in the surveys and investigations.
72．What is the best title of this passage?
A．China Fights AIDS B．Young People—Most likely AIDS Victims
C．AIDS Information Is Necessary D．AIDS—A Deadly Disease

Anxiety is the proper emotion when the immediate personal terror — of a volcano, an arrow, a stab（刺伤）in the back and other disasters — is directed against one’s self–disappears.
The kind of world that produces anxiety is actually a world of relative safety, a world in which no one feels that he himself is facing sudden death. The anxiety exists as an uneasy state of mind, in which one has a feeling that something unspecified（不具体的）and indeterminable may go wrong. If the world seems to be going well, this produces anxiety — for good times may end. If the world is going badly — it may get worse. Anxiety tends to be without focus；the anxious person doesn’t know whether to blame himself or other people. He isn’t sure whether it is a change in climate or the atom bomb that is to blame for this unclear sense of unease.
It is clear that we have developed a society which depends on having the right amount of anxiety to make it work. While we agree that too much anxiety is harmful to mental health, we have come to rely on anxiety to push us into seeing a doctor about a symptom（症状）which may indicate cancer, into checking up on that old life–insurance policy which may have out–of–date provisions in it, into having a conference with Bill’s teacher even though his report card looks all right.
People who are anxious enough keep their car insurance up, have the brakes checked, and don’t take a second drink when they have to drive. People who are too anxious either refuse to go into cars at all or drive so tensely that they help cause accidents. People who aren’t anxious enough take chance after chance, which increases the terrible accidents of the roads.
1. In the world that produces anxiety, _____.
A. people have sudden uneasiness        B. everything goes well
C. people are clear about their life        D. danger is almost everywhere
2. The author holds that _____.
A. anxiety is a good thing
B. anxiety is a symptom of mental illness
C. some anxiety can lead to changes for the better
D. no anxiety is bad for society
3. Accidents of the road tend to be caused by _____.
A. all those who are too anxious           B. all those who have anxiety
C. those who have no anxiety             D. those who are not anxious enough
4. The best title for the passage would be _____.
A. Anxiety                            B. The Right Amount of Anxiety
C. Anxiety vs Safety                    D. Different Attitudes to Anxiety
