suit” an airman’s suit designed to function as aparachute in the event of an emergency. Alas, the chute failed to open up, which contributed to his death. The event was recorded in still photos as well as in the grainy video below. 5. Evan O39。 Neill Kane took out his own appendix 阑尾) . Dr. Kane, a surgeon working in Pennsylvania in the early 20th Century, wanted to find out about appendix. On Feb. 15, 1921, he chose to perform the surgery himself and take out his appendix. But he calmly pushed them back in and kept working. 6. Werner Forssmann stuck a plastic tube in his own heart. In the early part of the last century, it was believed that inserting something into a beating heart would be deadly. Werner Forssmann thought other wise. So one day in 1929, he put a tube into his heart. Fortunately he survived the daring experiment but lost his job. But his fearlessness was rewarded when he won a Nobel Prize in 1956. 7. Frederick Hoelzel ate glass. And not just glass. During the 1920s and 1930s, University of Chicagoresearcher Frederick Hoelzel reportedly swallowed grain, glass, ball bearings, thread, wire, and other nonfood items in order to show how long it would take the items to pass through his guts(肠子) . Despite his risky research, Hoelzel lived into old age. 8. Barry Marshall drank bacterialoaded soup. For many years doctors had only an unclear idea about the cause of stomach illness. So he decided to be his own pig, taking germs from an infected patient, mixing the min a solution, and drinking it. A few days later, after experiencing a period of throwing up and tiredness, he examined his own gutand proved the link between the germs and illness. For his daring experiment he won a Nobel Prize in 2020. 46. Which of the following scientist’s research certainly was recorded by video? A. Newton. B. Minovici. C. Hoelzel. D. Reichelt. 47. Why did Werner Forssmann and Barry Marshall win the Nobel Prize? A. The two scientists were expert in surgery operations. B. Both discovered the links between germs and disease. C. They made significant breakthroughs in medical research through their brave experiments. D. Each of them conducted the same experiment separately. 48. In which experiment did a scientist lose his life? A. Riding a rocket chair. B. Eating glass. C. Sticking a needle in his eye. D. taking out his own appendix. 49. The greatest difference of the 8 scientists from the majority of other scientists is that_______. A. they devoted their time to scientific research B. they would risk their lives for experiments C. they were greatly enthusiastic about science D. they made their great contributions to science C Computer power is moving into the “cloud”—works of data centres that use the Inter to supply all kinds of services, from and social works to data storage and analysis. The rise of cloud puting is rapid and causing huge changes in the tech industry. The old guard is suffering: this week’ s $67 billion merger (合并 ) between Dell and EMC, makers of puters and storage device s respectively (分别 ), was a marriage forced by the rise of the cloud. The gains for customers have been equally dramatic. Compared with older IT systems, cloud puting is often much cheaper. It adds tremendous flexibility: firms that need more puting capacity no longer have to spend weeks adding new servers and installing software. In the cloud they can get hold of it in minutes. Their applications can be updated continually, rather than just every few months. Individual users can reach theirs, files and photos from any device. And cloud services also tend to be more secure, since providers know better than their customers how to protect their puting systems against hackers. But cloud puting makes one problem worse. In the old IT world, once a firm or a consumer had decided on an operating system or database, it was difficult and costly to switch to another. In the cloud this “ lockin” (锁定 )is even worse. Cloud providers try their best to make it easy to upload data. They accumulate huge amounts of plex information, which cannot easily be moved to an alternative provider. Cloud firms also create a world of interconnected services, software and devices, which is convenient but only for as long as you don’t venture outside their universe. Being locked in to a provider is risky. Firms can start to tighten the screws by increasing prices. If a cloud provider goes bust (崩溃 ), its customers may have trouble getting back their data. These risks have already caused a debate about whether the cloud needs stricter regulation. Some European politicians want to force cloud providers to ensure that data can be moved between them. That is too heavyhanded, because strict rules will prevent innovation in what is still a young industry. The history of puting suggests that mon standards may well appear naturally in response to customers’ demands—just as in personal puters, where it is now much easier to use the same files on different systems. In the meantime, a few monsense measures can reduce the risk of lockin. Firms that use more than one cloud provider to host their data are less affected. So are those that keep their most important information in theirown data centres. Consumers can take precautions, too. Some services are better than others at enabling users to move data between providers (Google does well on this score). Cloud puting promises its users many benefits, but don’t mistake it for some sort of digital heaven. 50. The author takes “the merger between Dell and EMC” for example to show ________. A. the influence of cloud puting on puter and storage device makers B. the miserable sufferings of old puter panies C. the rapid developme。
