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 ages 6 months through 18 years receive the flu vaccine.
Vaccines battle diseases caused by bacteria and viruses. A weakened form of the germ is introduced into the body. The body makes special substances called antibodies to fight the germs. If the actual germs were to attack, the antibodies would fight them.
Because there are many kinds of flu viruses, scientists must create a new vaccine formula (配方) each year. Researchers must make a prediction.
“The flu vaccine is not as effective as the polio (小儿麻痹症) vaccine or the measles(麻疹) vaccine,” says Dr. William Schaffner of Vanderbilt University School of Medicine.
“It’s not a great vaccine, but it is 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 from 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. Scientist say that it is not possible, because the viruses in the flu shot are inactivated (灭活的). But some minor side effects such as low-grade fever and body aches could occur. If they do, they begin soon after the shot and usually last only one to two days.
60. What is an antibody?
A. An antibody is a vaccine formula
B. An antibody is a germ that is introduced into the body

A. Not everyone is suitable for the flu vaccine.
B. The flu vaccine is not so effective as the measles vaccine
C. Flu viruses create new vaccine formulas each year.
D. People can’t take the flu vaccine at anytime.
62. It can be inferred from the text that _____.
A. scientists should change the vaccine formula each year
B. vaccines can battle diseases caused by bacteria and viruses
C. all children ages 6 months through 18 years can receive the flu vaccine
D. scientists are responsible for the side effects of the flu vaccine
63. Which of the following would be the best title for the text?
A. The flu vaccine B. Side effects of the flu vaccine

An Australian man who has been donating(捐献) his extremely rare kind of blood（血液） for 56 years has saved the lives of more than two million babies.
James Harrison has an antibody（抗体） in his plasma(血浆) that stops babies dying from Rhesus disease, a form of severe anaemia(贫血). He has enabled countless mothers to give birth to healthy babies, including his own daughter, Tracey, who had a healthy son thanks to her father's blood.
Mr. Harrison has been giving blood every few weeks since he was 18 years old and has now racked up a total of 984 donations. When he started donating, his blood was deemed so special that his life was insured（保险） for one million Australian dollars.
He was also nicknamed the “man with the golden arm” or the “man in two million”. He said, “I've never thought about stopping. Never!” He made a pledge to be a donor aged 14 after undergoing major chest surgery in which he needed 13 liters of blood. “I was in hospital for three months,” he said. “The blood I received saved my life so I made a pledge to give blood when I was 18.”
Just after he started donating he was found to have the rare（稀有的） and life-saving antibody in his blood. At the time, thousands of babies in Australia were dying each year of Rhesus disease. Other newborns suffered permanent(永久的) brain damage because of the condition. The disease creates an incompatibility between the mother's blood and her unborn baby's blood. It stems from one having Rh-positive（阳性） blood and the other Rh-negative（阴性）.
His blood has since led to the development of a vaccine called Anti-D. After his blood type was discovered, Mr. Harrison volunteered to undergo a series of tests to help develop the Anti-D vaccine. “They insured me for a million dollars so I knew my wife Barbara would be taken care of,” he said. “I wasn't scared. I was glad to help. I had to sign every form going and basically sign my life away.”
Mr. Harrison is Rh-negative and was given injections of Rh-positive blood. It was found his plasma could treat the condition and since then it has been given to hundreds of thousands of women. It has also been given to babies after they are born to stop them developing the disease.
It is estimated he has helped save 2.2 million babies so far. Mr. Harrison is still donating every few weeks now.
【小题1】How old is James Harrison?

【小题2】What does the underlined phrase “two million” refer to?

【小题3】Why did James decide to donate his blood? Because _____.

【小题4】The sentence “The disease creates an incompatibility between the mother's blood and her unborn baby's blood” (underlined in Paragraph 5) suggests that _____.

A．the mother and the baby have different types of blood

B．babies suffer permanent brain damage before born

C．Rhesus disease contributes to permanent brain damage

D．all the patients have a rare antibody in their blood

【小题5】What can we infer from the sixth paragraph?

A．His wife Barbara needed to be taken care of badly then.

B．Mr. Harrison was not glad to help develop a new vaccine.

C．Some of the tests to develop the vaccine are dangerous.

The koala, one of Australia’s most treasured creatures, is in trouble.

Affected by habitat (栖居地) loss and climate change, like many other uniquely Australian animals, koalas are being squeezed into smaller regions. But at present, it is a deadly disease, a somewhat silent killer that causes a further decline in the koala population, that is worrying many scientists about the fate of the koala.

The killer is Chlamydia, which has caused symptoms in up to 50 percent of the wild koalas, with probably even more infected (感染) but not showing symptoms. It has been particularly severe in Queensland, where nearly all koalas are infected. The disease causes many symptoms including eye infections, which can lead to blindness, making it difficult for them to find their primary food.

Treating Chlamydia in wild koalas is a challenge. There is no treatment available for it. Only a small percentage of the animals can be treated successfully and returned to the wild. Besides, there is no national plan in Australia to save the koala; it is up to each region to make management plans for its koala population.

The good news is that researchers are working to test a vaccine (疫苗) that would help prevent further spread. If all goes well, plans can be carried out to distribute the vaccine more widely. But it’s impossible to vaccinate (给注射疫苗) all wild koalas.

Another possibility would be to make vaccine distribution a routine part of treatment for the thousands of koalas brought into care centers every year after they are injured by cars or dogs.

While it is a combination of problems that are affecting the wild koala population, many experts believe this vaccine would be an important step in helping koalas survive longer. It may be enough time to give researchers a chance to solve some of the other problems facing Austalia’s koalas.

1.Which isn’t considered the main cause of koala’s population decline?

A. A deadly disease.

B. Injuries from cars and dogs.

C. Climate change.

D. Habitat loss.

2.The third paragraph mainly tells us .

A. the serious result Chlamydia has caused to the koala

B. Chlamydia affected the koala only in particular regions

C. the most serious symptom of Chlamydia is eye infections

D. Chlamydia can seriously affect koala’s primary food

3.We can learn from the text that the vaccine .

A. would cure the killer Chlamydia quite effectively

B. would only be distributed in koala care centers

C. has already been put into practical use in Australia

D. cannot be distributed to all the infected koalas

4.It can be inferred from the text that .

A. a national plan for saving koalas will be made soon in Australia

B. koala population is declining only in a few regions

C. researchers need enough time to solve the koala problems

D. experts have lost the best chance to save the infected koalas

The doctor said jokingly that his own infection of the virus _______ the discovery of a vaccine (????)of the disease.
