Did you get a flu shot this year?For the first time,the Centers for Disease Control and Prevention in the US is recommending that all children aged from 6 months to 18 years receive the flu vaccine.
Vaccines battle diseases caused by bacteria and viruses.A weakened form of the germ (病菌) is introduced into the body.The body makes special substances called antibodies (抗体) to fight the germs.If the actual germs were to attack,the antibodies would fight.Because there are many kinds of flu viruses,scientists must create a new vaccine formula (处方) each year.Researchers must make a prediction.
It is like forecasting the weather.Sometimes they are right on,and sometimes they are off.But even when the vaccine does not closely match circulating flu types,it can make the illness less serious.
“The flu vaccine is not as effective as the polio (小儿麻痹症) vaccine or the measles vaccine,” says Dr.William Schaffner of Vanderbilt University School of Medicine.“It’s not a great vaccine,but it is in fact quite a good vaccine.”
But a flu vaccine doesn’t work for everyone.There are certain people who should be careful about taking it,because the vaccine is produced in eggs.Those who are allergic (过敏的) to eggs should not take it.If you have a fever,you should wait until you recover.
Some people are afraid that they might get the flu from the flu shot.Scientists say that it is not possible,because the viruses in the flu shot are inactivated.But some minor side effects such as lowgrade fever and body ache could occur.If they do,they begin soon after the shot and usually last only one to two days.
Did you know?Smallpox was the first disease people tried to prevent by putting a virus into a healthy person.In 1796,English scientist Edward Jenner placed some infected material under a boy’s skin.
1.The underlined word “vaccine” (in Para.1) refers to________.
A.virus used for fighting against disease
B.antibody to fight the germs
C.formula to fight against disease
D.germ to be injected into the body
2.By saying “It’s not a great vaccine,but it is in fact quite a good vaccine.” (in Para.4),William Schaffner means the flu vaccine________.
A.is as effective as the polio and the measles vaccines
B.is worse,compared with the polio and the measles vaccines
C.does help to make illness less serious
D.is quite good because it works for everyone
3.We can infer from the passage that________.
A.those who are not allergic to eggs can take the flu vaccine
B.not all the flu vaccines are effective for everyone
C.you should go to a doctor if you have a fever after taking the flu vaccine
D.it is possible that some people might get the flu from the flu shot
4.When people take the flu vaccine,________.
A.they’ll be allergic to eggs
B.their bodies will ache for 5 days
C.they probably have a low fever
D.they won’t catch a flu ever after

Here’s an idea whose time has come: A flu shot that doesn’t require an actual shot.
For the first time, researchers have tested a flu vaccine patch (疫苗贴) in a human clinical trial and found that it delivered as much protection as a traditional injection with a needle. Doctors and public health experts have high hopes that it will increase the number of people who get immunized (免疫的) against the flu.
Seasonal flu is responsible for up to half a million deaths around the world each year according to the World Health Organization. A team led by Georgia Tech engineer Mark Prausnitz has come up with an alternative method that uses “microneedles”. These tiny needles are so small that 100 of them, arranged in order on a patch, can fit under your thumb (拇指). Yet they’re big enough to hold vaccine for three types of flu.
None of the study volunteers had serious side effects. The groups that got patches had mild skin reactions that were not seen in the regular needle group, while the volunteers in the regular needle group were more likely to experience pain. Overall, 70 percent of the volunteers who got vaccine patches said they’d rather use them again than get a traditional flu shot. The study authors declared it a success on all fronts.
The biggest beneficiaries could be people in low-and-middle—income countries, where flu vaccines are hard to come by. Reducing pain is nice, but other benefits-the patch costs less, is easier to transport, doesn’t require refrigeration, can be self-administered and doesn’t cause waste of needles — are even better.
“Microneedle Patches have the potential to become ideal candidates for vaccination programs,” wrote Katja Hoschler and Maria Zambon of Public Health England.
1.What is the passage mainly about?
A. A vaccine patch that cures people of their flu.
B. A clinical study that protects people from disease.
C. A patch that makes flu shots a thing of the past.
D. A method that makes traditional flu shots painless.
2.What do we know about the vaccine patch?
A. It is produced by the WHO.
B. It causes slight side effects.
C. It delivers vaccine to the little finger.
D. It works badly on 30% of the volunteers.
3.The new patch has all the following benefits except that .
A. it is provided free of charge
B. it can be used without a doctor
C. it can be kept at room temperature
D. it needs less care in transportation
4.What is Katja and Maria’s attitude towards the new shot?
A. Cautious. B. Favorable.
C. Ambiguous. D. Disapproving.

A deadly strain of avian flu may have passed between people for the first time, experts believe.The avian influenza A (H7N9) virus is thought to have been transmitted between father and daughter in eastern China, according to research published online by the British Medical Journal (BMJ).
The findings provide the strongest evidence yet of H7N9 transmission between humans since its discover in February, but its ability to transmit itself was deemed "limited and non-sustainable" by the Chinese researchers behind the study.At the end of June 133 cases had been reported, including 43 deaths. Most infections have been among people visiting markets, selling live birds or among those who had contact with live poultry(家禽) in the seven to 10 days before becoming ill.
The latest study examined the case of a 60-year-old father who regularly visited a live poultry market and became ill five to six days after his last visit in March. He was admitted to hospital with fever, cough and shortness of breath. Despite intensive care treatment he died of multiple organ failure on 4 May. His 32-year-old daughter, who was previously healthy, looked after him at his bedside before he was admitted to intensive care. She had no known exposure to live poultry before falling ill with a very high temperature, cough and fever. The daughter developed symptoms six days after her last contact with her father and was admitted to hospital where she died of multiple organ failure on 24 April.
Follow-up investigations(调查) uncovered almost genetically identical virus strains from each patient, suggesting transmission from father to daughter. Another 43 people were also tested who had had close contact with the father, daughter or both.
Dr Peter Horby, senior clinical research fellow at the Oxford University Clinical Research Unit in Hanoi, Vietnam, said of the study: "The most likely source of infection for the daughter was her father, during the period that she cared for him while he was ill. "He said “limited person to person transmission had been reported for other strains like H5N1 , H7N7, and the pig origin flu virus H3N2. Those strains had been around for more than a decade but have not progressed any further down the path towards a world-wide virus.” “Limited human-to-human transmission of H7N9 virus is therefore not surprising, but strengthening to monitor it was still needed,” Dr Horby added.
1.What’s the main idea of the passage ?
A. The findings about H7N9 transmission only between father and daughter .
B. H7N9 transmission may be spreading between people .
C. 133 cases of H7N9 transmission have been reported .
D. Both the father and daughter died of multiple organ failure.
2.The reason why the daughter died of multiple organ failure was that _____.
A. she fell ill with a very high temperature, cough and fever.
B. she was exposed to live poultry before falling ill.
C. she had close contact with the father while caring for her sick father .
D. she sold live birds in five to six days before falling ill .
3.Which of the following is Wrong about H7N9 transmission?
A. It was limited and non-sustainable
B. It was person to person transmission
C. It wasn’t progressed any further down the path towards a world-wide virus.
D. It happened between father and daughter .
