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 inpatibility 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.

(答案→)A
解析：
【小题1】A 计算题。根据第1,3段An Australian man who has been donating(捐献) his extremely rare kind of blood（血液） for 56 years和Mr. Harrison has been giving blood every few weeks since he was 18 years old 说明他18岁开始鲜血，献了56年，故现在的74岁。故A正确。
【小题2】.B 细节题。根据第一段第2行has saved the lives of more than two million babies.说明这里的“two million指babies 。故B正确。
【小题3】D 细节题。根据第四段2,3,4行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.”说明Ｄ正确。
【小题4】A 推理题。根据横线下一句It stems from one having Rh-positive（阳性） blood and the other Rh-negative（阴性）.可知母亲和孩子的血型不一样，故A正确。
【小题5】C 推理题。根据倒数第三段后三行“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.”给他做了100万的保险，说明该实验有一定的危险性，故C正确。
