Passage One
Uncle Sam is a tall, thin man. He’s an older man with white hair and a white beard. He often wears a tall hat, a bow tie, and the stars and stripes of the American flag.
Who is this strange, looking man Would you believe that Uncle Sam is the U.S. government But why do you call the U.S. government Uncle Sam
During the War of 1812, the U.S. government hired meat packers to provide meat to the army. One of these meat packers was a man named Samuel Wilson. Samuel was a friendly and fair man. Everyone liked him and called him Uncle Sam.
Sam Wilson stamped the boxes of meat for the army with a large U.S. for United States. Some government inspectors came to look over Sam’s company.
They asked a worker what the U.S. on the boxes stood for. As a joke, the worker answered that these letter stood for the name of his boss, Uncle Sam.
The joke spread, and soldiers began saying that their food came from Uncle Sam.
A. ask
B. stand for
C. look over
D. see
An Indian boy ran swiftly from a village in Mexico. In his hand he carried a basket of fish. Only a few moments before, the fish had been pulled from the cold water of the lake. Farther on, another runner was waiting to take the basket from the tired boy and to race on. And so from one swift runner to another, fresh fish were rushed from the lake to the dinner table of Montezuma, ruler of the Aztecs.
Speed is important in transporting fish and many other fresh foods. Foods that spoil easily must reach the market and the dinner table as quickly as possible. But now planes, trucks, trains, and ships have replaced runners.
Planes are the fastest way to transport food. They are especially useful in carrying food to people and animals that could not be reached otherwise. Suppose there were a flood or an earthquake and the people could not be reached by trains or trucks. Unless packages of food could be dropped
A. food transportation
B. perishable food transportation
C. comparison of modern food transportation and the past one
D. advantages of food transportation by planes, ships, trains and trucks
| 阅读下面短文，回答文后问题。 20世纪80年代，“网际互联协议”使得人们可以连接任意两台计算机，这样，一个巨大的网络——因特网——在全球蔓延开来。20世纪90年代，随着“超文本传输协议”的出现，人们可以链接任意两个文件，这样，一个庞大的在线图书馆兼大卖场般的万维网在因特网上迅速形成。到了今天，新的协议又出现了，它就是“网格协议”。网格协议使得人们几乎能够链接与计算机有关的其他任何东西：数据库、虚拟和可视化工具，甚至是计算机本身的计算能力。 美国阿贡国家实验室的伊恩•福斯特说：“人类正在迈向一个新的未来，计算机资源的实际位置已不再重要。“福斯特和南加州大学信息学院的卡尔；克塞曼是网格计算领域的先驱者，他们主张网格计算类似于电网，而且需要有一个协议来支持。这种协议是实现网格计算的基本条件，因为它能够保证异构系统工作起来像单一的系统那样协调，能够使家庭和公司的计算机有能力进入到网络中寻找和调用资源而______。他们与其他人一起开发了Globus Toolkit这种能在各种平台上运行的网格计算软件，并使之成为实际上的网格计算标准，也就是网格协议。 克塞曼说：“设想一下，如果你是一个应急小组的领导，正在处理一起重大有毒化学物泄漏事故，你可能想要了解事故的有关情况，如泄漏物中含有哪些化学物，预报的天气状况如何，它们对事故处理有什么影响，现在的交通状况怎样，它对疏散线路有什么影响……要在今天的因特网上找到这些问题的答案，是一件十分麻烦的事，因为登录步骤的繁琐和软件的不兼容随时可以使你陷入困境，而如果采用网格计算，问题的解决将变得易如反掌。网格协议不但为人们发现、访问和调用几乎所有的在线资源提供了标准的平台，而且也为安全和认证等要求提供了相应的解决方案。” 网格计算技术的最直接应用之一是网格计算机的研制和开发。目前，世界各地正在建造很多台网格计算机，它们都得到了许多丌业巨头，如IBM公司、SUN公司和微软公司等的大力支持。事实上，所有这些计算机都采用了Globus Toolkit，拥有前所 A. 网格计算技术及其应用 B. 网格计算机与网络资源的全面共享 C. 网格计算机与网格计算技术 D. 网格协议及网格计算方法 [单项选择]葛根采用的炮制方法是（）

A.安全生产权力清单 B.安全生产责任清单 C.安全生产考核清单 D.风险因素清单 [单项选择]患者，女，32岁。下腹部有包块2年多，伴月经量增多，前来某医院就诊。门诊接诊医师检查，初诊为"子宫肌瘤"。入院后，进修医师按"子宫肌瘤"书写了病历。经治医师在没有做宫腔长度及B超等检查的情况下，完全相信了门诊的诊断，自行决定做子宫切除术。术前，未执行上级医师"再详细探宫腔"的指示；术中，发现子宫体较软时，助手提示"需排除妊娠可能"，术者仍未听取，在未行子宫穿刺的情况下，错误地将子宫及双侧卵巢全切。切开子宫，见一胎儿。该患者已生有一男一女，系绝育对象。术后，医务人员对是否向患者家属讲明实情，持赞成和反对两种意见。若将事故实情告知患者家属，针对手术者应负的道德责任，最正确的说法是（）。
A. 违背"审慎"的医德要求，未作必要的认真的检查，造成医疗事故。 B. 经验不足，对技术常规不熟悉，系医疗事故 C. 虽错误切除子宫，但同时为患者做了需做的人流和绝育手术，功过参半 D. 手术未造成其他伤害，患者应予谅解 E. 门诊接诊医师、手术助手、上级医师均应负道德责任 [填空题]
