题目列表(包括答案和解析)

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.

阅读下列短文，从每题所给的（A、B、C和D）四个选项中，选出最佳选项。

Vitamin Supplements:More May Be Too Much

　　Vitamins are meant to improve people's anti- disease systems，and with the spread of SARS and bind flu，many Chinese are taking vitamins A,C,and E every day．

　　But some US researchers say that vitamin supplements（补充）cannot correct a poor diet，and that multivitamins havenot been shown to prevent any disease．It is also easy for highdoses（剂量）of certain vitamins and minerals to increase therisk of disease actually．

　　Experts say they are no longer concerned about the lackof vitamin．Those are almost unheard of today,even with thepopulation eating fewer fruits and vegetables．Instead，theconcern is with the dangers of vitamin excess（过量）．

　　Dr Beniamin Caballero,a member of the Food and Nutrtion Board at the US National Academy of Sciences,said thatfor some supplements,including vitamin A,the difference between the advised dose and the dose that could lead to diseaselike osteoporosis(bone disease)was not large．Popular multi-vitamins he added,often contain what could be risky dose．

　　Similar questions are being raised ahout other vitamins and minerals,particularly iron and vitamins E and C．

　　Researchers say the questions involve multivitamins taken by healthy people,not particular vitamins or minerals taken by groups with special needs．Some elderly people,for exam ple,may lack B12 because they lose their ability to absorb itfrom foods．People who spend little time outdoors may require vitamin D,which the skin makes when it is exposed to sunlight．Even when older people are in the sun,aging skin loses much of itS ability to create the vitamin．

　　“If you eat a poor diet every day,vitamins are the least of your many problems,”said Dr Caballero．“You cannot replace a healthy diet．People are looking for the magic bullet which doesn't exist．”

(1)

From the second paragraph,we can find that ________
[　　]
A．	parents should prevent their children from taking vitamins
B．	doctors shouldn't use any vitamins on their patients
C．	too much vitamins can increase the risk of disease
D．	high dose of certain vitamins can prevent diseases

(2)

[　　]

[　　]
A．	is dangerous for people to take
B．	is very useful to bone disease
C．	should be taken with care
D．	should be taken by a large amount

(4)

　　While the threat of a reappearance of SARS is still there, it is reassuring to learn about the latest developments in vaccine research．

　　More than 1,400 vaccine shots for SARS have been produced in China, and an application for clinical tests has been referred to the State Food and Drug Administration(SFDA), according to a Xinhua report on Sunday．

　　“If everything goes smoothly, conducting of clinical experiments will be agreed before the end of December,”said Ying Hongzhang, head of Biological Product Section of the SFDA．

　　So far, China is far ahead of other countries in the search for a SARS vaccine, claimed Yin．At that time, volunteers will be sought in Beijing and Guangzhou to take part in experiments using the new vaccine．However, while cheering for the research breakthrough, voices of reason should also be heard．

　　What medical workers should always maintain is a cool head and careful attitude, which are essential in any scientific research．This is especially true when conducting experiments on human beings, because they are directly concerned with the volunteers’ health and even their lives, and also because knowledge of the deadly virus(病毒)still too limited．

　　Media reports indicate that members of the public are reacting actively to the news of selecting volunteers and are expressing their readiness．Their courage is well worth our admiration．The trust they are placing in these medical researchers is the biggest support of their work．

　　The researchers have no other choice but to be highly cautious in the expected experiments．The safety of volunteers should always be the first consideration．Scientists from different countries have been put in a race in uncovering the mystery surrounding the virus．But to play a leading role should by no means be the ultimate pursuit(最终目的)of the scientific workers．It is people’s safety and health that remain the biggest concerns．

　　While there are still so many mysteries to be solved, it is too early to celebrate．
