Scientists say Sever Acute Respiratory Syndrome (SARS) is caused by a new virus from the family of corona viruses (冠状病毒), which also causes the common cold.
WHAT ARE THE SYMPTOMS?
The World Health Organization says the main symptoms of SARS are high fever (over 38℃), dry cough, shortness breath or breathing difficulties. Changes in chest X — rays, which are indicative of pneumonia (肺炎), also occur. SARS may be associated with other symptoms, including chills, headache, muscular stiffness, loss of appetite, malaise, confusion, rash and diarrhea.
Health experts say the disease has an incubation period (潜伏期) of between two-to-seven days, with three-to-five days being more common before victims start showing flu-like symptoms.
HOW DANGEROUS IS IT?
The mortality rate (死亡率) appears to be between 3 to 5 per cent. In Hong Kong, at least, those who infected invariably develop severe pneumonia, which can cause numerous complications. The victim's condition can deteriorate (恶化) very quickly in as little as five days.
WHAT IS THE TREATMENT?
There is currently no specific cure for the disease. But doctors worldwide have been treating it with ribavirin-an anti-viral drug-and steroids (类固醇). Doctors say if treated early most patients without other serious illnesses can recover.
HOW DOES IT SPREAD?
WHO (世界卫生组织) and Hong Kong experts say the virus spreads through droplets by sneezing or coughing and such direct infection (传染) can usually happen within a radius of around three feet.
The virus can also spread indirectly as it can survive outside of the human they for three to six hours. Contact with any object that is tainted by droplets containing the virus, for example, a contaminated phone, could lead to infection if a person then touches their eyes, nose or mouth.
Health experts have not ruled out that it could be airborne (空气传播的), which infinitely raises the contagious nature of the virus and would make it far harder to contain (控制).
1. Which of the following is NOT considered as one of the symptoms of SARS?
A. dry cough B. shortness of breath
C. bleeding D. loss of appetite
2. It is possible that a person will be infected with SARS if ________.
A. they touches their nose after contacting with a contaminated phone.
B. they don’t wash their hands twice a day.
C. they don’t know the contagious nature of the virus like health experts.
D. they don’t go to a doctor at once when they catch a cold.
3. Which of the following is NOT true according to the passage?
A. Even though there is currently no specific cure, the doctors can treat SAJS with an anti-viral drug.
B. Before victims show flu-like symptoms, SARS has an incubation period of between two-to-seven days.
C. That SARS could be airborne has not been ruled out by health experts from WHO.
D. Doctors believe that every victim without other serious illnesses can be cured.
4. From the information given in the passage we can deduce that ________.
A. SARS is a type of pneumonia which is caused by influenza.
B. When an infected person travels, he can not spread the virus to other passengers on his flight.
C. In order to control the spread of the disease, patients should be placed in an isolation unit.
D. Wearing a mask is not a good way of keeping off SARS.

查看习题详情和答案>>Jeremy Wirick, 9, has been back in school for less than two months, but he has already had several asthma(哮喘)attacks. A recent attack happened on October 2, after he pushed himself too hard in gym class. Running, power walking, jogging and push-ups took their toll. When Jeremy got home an hour or two later, he was out of breath. He needed to use a nebulizer, a machine that helps send medicine quickly to the lungs, to get his breathing back to normal.
Asthma attacks like Jeremy increase in September and October. More than six times as many asthma sufferers who are elementary-school age need hospital treatment in the fall as in the summer.
Experts believe many factors can contribute to back-to-school asthma. Kids get together in close spaces, they start passing viruses around. A viral infection can cause an asthma attack. There are also certain fall allergies(过敏症)that can cause attacks. Exercise is another common cause of an attack. Besides, the stress of school can make asthma worse.
Parents can play a big role in helping kids with asthma start the school year right. Dawne Gee’s10-year-old son, Alexander, has had asthma since he was a baby. Before the school year starts, she tells school workers in writing about her son’s asthma.
The Gees live in Kentucky, which has passed laws allowing students to carry their asthma medication(药物治疗)with them at school. Alexander’s mom makes sure he has his inhaler(人工呼吸器)with him when he goes to school and that he keeps it on hand at all times. In Delaware, where Jeremy lives, kids are allowed to carry their inhalers at school.
The American Lung Association says that about 6.2 million American children suffer from asthma. Asthma is the chronic (慢性) illness that causes students to miss the most days of school. There are many things that schools can do to help students control their asthma
