10.Post-holiday blood shortages are nothing new to hospitals.But last week,physician James Devitt at Miami Valley Hospital saw disaster appearing.For the first time ever,he called-surgeons at home and urged them to postpone all nonemergency surgeries requiring large amounts of blood.By the time he finished dialing,Devitt had persuaded surgeons to reschedule at least 14operations.Not that he was pleased by the delays."If we don't get some of these surgeries done soon,"Devitt says,"they could become emergencies."Miami Valley Hospital wasn't alone.Facing a national blood shortage,physicians in Atlanta,Pittsburgh,New York,Baltimore,and Washington moved to postpone nonemergency surgeries."We've never seen cancellations of surgeries like this,"says Melissa Macmilian,spokesperson for America's Blood Centers ( ABC )."It's absolutely the last way."
The blood shortage was so worrying that about half of all U.S.blood banks carried less than a one-day supply.Normally,they store three days'worth.Suppliers need the extra red cells on hand for emergencies like car accidents-one severely injured patient can quickly wipe out a hospital's entire blood supply.
This month's crippling (有严重后果的) blood shortage is worse than usual because winter storms forced cancellations of blood drives in the Midwest,considered America's"blood basket".Blood providers like ABC and the Red Cross count on that region to supply the rest of the country during normal shortages. But last week,icy roads kept donors away from blood banks,while school and workplace closings forced blood-drive organizations to cancel events.
Blood industry experts say the long-term outlook is hopeless.Hospitals need more blood to treat an aging population,and donations aren't keeping pace.Only 5% of those suitable donate,and even fewer people plan to give this year,according to a recent Harris Poll.The members of the most loyal donors,the World War II generation,are thinning.For the most part,the mid-aged say they are too busy,and young people are indifferent.

A.explain that blood shortage is not rare

B.One patient has used up a hospital's entire blood supply.
C.Red cells are usually more available than some other drugs.
D.Many suppliers are facing a marked shortage of blood stock.

B.Blood donation mainly comes from this area.

解答 71-75.CCDBB
71题答案:C 考查细节推理.第一段主要讲述由于血库存量有限,医生被迫暂时推迟一些手术.Devitt的话表明手术延期是不得已而为之.Not that he was pleased by the delays明确说明他不愿意这样做.故本题答案为C选项.
72题答案:C考查主旨概括.该段说明全国都面临血液短缺问题,许多城市只好推迟非急诊手术,发言人称这是最后一招.因此本题答案为C选项"全国性血液短缺的严重性".
73题答案:D考查细节推理.通常血库应有三天的备用量,但此时,约半数血库的储备量不足一天,说明库存量大幅下降.故本题答案为D选项.
74题答案:B考查细节推理.根据该段二、三行的considered America's"blood basket".Blood providers like ABC and the Red Cross count on that region to supply the rest of the country during normal shortages可知中西部是主要的供血地,故本题答案为B选项.
75题答案:B考查细节推理题.根据最后一段的young people are indifferent"年轻人很冷漠"可知B选项表达有误,故本题答案为B选项.
