1．What can you do after being accepted to do the volunteer work? A．Choose your proper time to stay there. B．Obtain the fund from the local police. C．Freely choose your own workmates. D．Go to any African country.

人与社会·公益事业与志愿服务 327 体裁 难度 记叙文 2

James Harrison, who was entitled “The Man with the Golden Arm”， has donated blood almost every week, saving more than two million babies in the process.

Harrison told CNN, an American channel, about why he chooses to donate, even though it's not the most pleasurable experience：“Never once have I watched the needle go in my arm. I can't stand the sight of blood, and I can't stand the pain.”

An amazingly unique antibody(抗体) in Harrison's blood makes it a true lifesaver for babies who could be affected by rhesus disease(Rh溶血症)．

The condition occurs during some pregnancies, when a woman who has rhesus-negative blood produces antibodies that destroy her babies' cells. This can happen when the baby has the same rhesus-positive blood as the father. Rhesus disease can cause health issues in babies. It can even result in death.

Harrison's blood helped physicians develop an injection called Anti-D in the 1960s, which prevents women who have rhesus-negative blood from developing the harmful antibodies while pregnant. After Harrison completes one of his routine donations, his blood can be used to create more vaccines(疫苗)．

“I started donating in 1955, two days after I turned 18，” Harrison said when he completed his 1, 075th donation.

As CNN reported, every Anti-D vaccine created in Australia has something to do with a donation from Harrison, who holds the record for the most blood donations in Australia.

“A number of mothers have come up to me and said, ‘Thank you very much for what you've done because I now have one, two, three healthy children.'” Harrison said.

Harrison's own daughter, Tracey Mellowship, had been one of the 17 percent of women who need Anti-D during their pregnancy. The injection helped guarantee her second son would be born healthy.

“Dad had always donated—we knew that，” Mellowship said. “But it didn't hit home until I was pregnant and knew the consequences.”

语篇导读 本文讲述了澳大利亚献血最多的人James Harrison的故事。

4．From the first two paragraphs we can infer that Harrison is ________. A．humorous and smart C．friendly but nervous

B．optimistic but weak D．brave and unselfish

解析 D 推理判断题。根据第一段Harrison几乎每周义务献血可知，他是无私的；根

3

据第二段可知，他受不了见血和针扎的疼痛，但他依然坚持频繁献血，因此他非常勇敢，故选D项。

5．Babies affected by rhesus disease ________. A．grow problematic cells B．can't form blood themselves

C．develop the disease after being born D．have the same blood type as their mothers

解析 A 细节理解题。根据第四段中的produces antibodies that destroy her babies' cells可知，Rh溶血症患儿的细胞被破坏，即会变成问题细胞，故选A项。

6．Harrison's blood can ________. A．help patients develop Anti-D B．cure rhesus disease affected babies C．avoid the risk of rhesus disease D．stop babies from producing antibodies

解析 C 推理判断题。根据第五段第一句可知，他的血液可以帮助医生研发Anti-D，从而避免Rh阴性血的孕妇产生伤害胎儿的抗体，即可预防溶血症，故选C项。

【误区警示】本题易误选A项，根据第五段中的helped physicians develop an injection可知，他的血液能帮助医生研制注射液，而不是直接帮助病人研制。

7．Before Mellowship was injected Anti-D, her family didn't ________. A．understand the meaning of Harrison's act B．expect she would have another healthy son C．know Harrison held a record for donating blood D．realize the high rate of potential rhesus disease

解析 A 细节理解题。根据最后两段可知，B、C项错误；D项内容文中未提及；而A项中的understand the meaning对应原文中的knew the consequences，故选A项。
