James Harrison is called “The Man with the Golden Arm”. The Australian man has saved the lives of more than 2.4 million babies by donating blood nearly every week for 60 years.

At the age of 14, Harrison had an 11-hour operation to remove a lung. “ I received 13 units(liters) of blood and my life had been saved by unknown people,” Harrison said. “When I’m old enough, I’ll become a blood donor.”

That is exactly what Harrison did. Soon afterwards, doctors told him that his blood contains a rare antibody that could help mothers who have rhesus disease, a condition where a pregnant woman’s blood attacks the blood cells of her fetus(胎儿). In worst cases, it can result in brain damager or death for the baby, and until about 1967, thousands of babies were dying each year in Australia.

Before long, researchers had developed an injection(注射剂), called Anti-D, using Harrison’s donated blood. Because about 17 percent of pregnant women in Australia require the Anti-D injections, the blood service estimates Harrison has helped 2.4 million babies in the country. At age of 81, he had already passed the age limit allowed for donors, and the blood service had decided　　 Harrison should stop donating to protect his health.

Harrison was awarded the Australian Medal of Honor in recognition of his extraordinary efforts and generosity, but he doesn’t consider himself a hero. He’s now donated his blood 1,173 times, which gained him a Guinness World Record. But in all those times of giving blood, he’s never once watched. “I look at the ceiling or the nurses, maybe talk to them a bit. I can’t stand the sight of blood, and I can’t stand pain.”

1.What contributed to Harrison’s becoming a blood donor?

A.The rare antibody in his blood B.His gratitude to the blood donors

C.The request from the blood service D.His pain during the removal of his lung

2.What’s Anti-D used to do？

A.Save babies by giving them injection B.Protect babies from common illness

C.Cure pregnant mothers with rhesus disease D.Prevent women’s blood from being attacked

3.What does Harrison hold the Guinness World Record for?

A.The age among blood donors B.The amount of blood he donated

C.The number of donations he made D.The number of babies he saved by donating

4.What does the author think of Harrison?

A.He is kind and curious B.He is generous and modest

C.He is selfless and shy D.He is sympathetic and cautious

The year 3700, Earth is far too hot for any human to call it home. On this planet at least, man is nothing more than a memory--if there is anything left to remember the "wise man". But what about our wisdom--will any of it survive us?

The conventional answer is no. Knowledge requires a knower, and there will be no knowing minds around then. But if information survives, perhaps in books or hard drives, maybe the knowledge isn't quite dead but dormant(休眠), ready to become alive with the help of other minds that develop over time or come to visit Earth in the distant future.

At first sight, that seems to be reasonable: after all, we have done similar things with past knowledge. For example, we saved an ancient computer from a ship destroyed at sea off the southern coast of Greece, and succeeded in finding the meaning of Egyptian hieroglyphics(象形文字). Careful work can bring previously lost wisdom back to life.

However, the key point is that there is a certain cultural continuity with those ancient times that allows us to reason and make progress in the dark: we know we are dealing with the legacy(遗产)of other humans. Without that link, the survival of objects and raw data doesn't guarantee the survival of knowledge. And a lack of continuity in language with any future intelligence would be a barrier. Knowledge is closely connected with language. When a language dies out, we can lose systems of reasoning that they contain. If that's lost, then it can't be recovered.

All this means that other minds might not be able to fully make human knowledge alive when we are gone. It is better to concentrate on not dying out in the first place.

1.How many opinions are mentioned in Para.2?

A. One.

B. Two.

C. Three.

D. Four.

2.What does the underlined phrase "similar things" in Para. 3 probably refer to?

A. Making lost wisdom alive again.

B. Rescuing disappearing knowledge.

C. Preserving future knowledge.

D. Gaining new knowledge.

3.How can we make knowledge survive?

A. We know a lot about human beings.

B. We learn ways to draw conclusions.

C. We have a certain cultural continuity.

D. We protect the legacy of other humans.

4.What's mainly talked about in the text?

A. Can human beings live on?

B. Will our knowledge survive us?

C. What will the earth be like in the future?

D. How can we protect our culture?

However， the key point is that there is a certain cultural continuity with those ancient times that allows us to reason and make progress in the dark： we know we are dealing with the legacy （遗赠） of other humans．
