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.
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.
50. How old is James Harrison?
A. 74 B. 70. C. 56 D. 78
51. What does the underlined phrase “two million” refer to?
A. mothers B. babies C. dollars D. blood
52. Why did James decide to donate his blood? Because _____.
A. his daughter asked him to help her son B. he has a golden arm worth a million dollars
C. a vaccine called Anti-D is to be developed D. someone else’s blood saved his life
53. 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
54. 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.
D. His blood type was accidentally discovered after tests.
查看习题详情和答案>>by 12 years, sobering new research suggests.
The findings are from study that tracked nearly 5 000 British adults for 20 years, and they highlight yet
another reason to adopt a healthier lifestyle.
Overall, 300 people studied had all four unhealthy behaviors. Among them, 90 died during the study, or
30 percent. Among the 400 healthiest people with none of the four habits, 8 percent of them died.
The risk behaviors were., smoking tobacco; drowning more than three alcoholic drinks per day for men
and more than two daily for women; getting less than two hours of physical activity per week; and eating
fruits and vegetables fewer than three times daily.
These habits combined substantially increased the risk of death and made people who engaged in them
seem 12 years older than people in the healthiest group, said lead researcher Elisabeth Kvaavik of the
University of Oslo.
The healthiest group included never-smokers and those who had quit; women who had fewer than two
drinks daily and men who had fewer than three; those who got at least two hours of physical activity weekly;
and those who ate fruits and vegetables at least three times daily.
"You don't need to be extreme" to be in the healthy category, Kvaavik said. "These behaviors add up, so
together it's quite good. It should be possible for most people to manage to do it."
The US government generally recommends at least 4 cups of fruits or vegetables daily for adults,
depending on age and activity level, and about 2 hours of exercise weekly.
B. You would feel tired, lack of energy.
C. You may look older than you really are.
D. You may face the risk of death of cancer.
B. 24.
C. 56.
D. 120.
B. The results of four bad life habits.
C. The findings of a new research.
D. The recommends from the US government.
