26、tudy for as many years as a doctor. However, each must be equally dedicated. Caring for sick persons requires a great deal of patience and concern. Most nurses work long days, and they often must work at odd hours or during the night.Under the supervision of the head nurse, the nursing staff must pr
27、ovide nursing services on a 24-hour basis and attend to patients needs. This responsibility continues around the clock, and so nurses must work in shifts.

Attaching radio devices to it is difficult a
34、nd visual sightings are too unreliable to give real insight into its behavior.So biologists were delighted early this year when with the help of the Navy they were able to track a particular blue whale for 43 days monitoring its sounds. This was possible because of the Navys formerly top-secret syst
35、em of underwater listening devices spanning the oceans. Tracking whales is but one example of an exciting new world just opening to civilian scientists after the cold war as the Navy starts to share and partly uncover its global network of underwater listening system built over the decades to track
36、the ships of potential enemies,Earth scientists announced at a news conference recently that they had used the system for closely monitoring a deep-sea volcanic eruption for the first time and that they plan similar studies. Other scientists have proposed to use the network for tracking ocean curren
37、ts and measuring changes in ocean and global temperatures. The speed of sound in water is roughly one mile a second, slower than through land but faster than through air. What is most important, different layers of ocean water can act as channels for sounds focusing them in the same way a stethoscop
38、e does when it carries faint noises from a patients chest to a doctors ear. This focusing is the main reason that even relatively weak sounds in the ocean especially low-frequency ones can often travel thousands of miles.（分数：5.00）(1).The passage is chiefly about _.（分数：1.00）A.an effort to protect an
39、endangered marine speciesB.the civilian use of a military detection systemC.the exposure of a Navy top-secret weaponD.a new way to look into the behavior of blue whales(2).The underwater listening system was originally designed _.（分数：1.00）A.to trace and locate enemy vesselsB.to monitor deep-sea volc
40、anic eruptionsC.to study the movement of ocean currentsD.to replace the global radio communications network(3).The deep-sea listening system makes use of_. A the sophisticated technology of focusing sounds under water B the capability of sound to travel at high speed C the unique property of layers
41、of ocean water in transmitting sound D| low-frequency sounds traveling across different layers of water（分数：1.00）A.B.C.D.(4).It can be inferred from the passage that_.（分数：1.00）A.new radio devices should be developed for tracking the endangered blue whalesB.blue whales are no longer endangered with th

44、 was Sunday, and three games were played in the two cities. The people playing them and the people watching them tell us much about the ever-changing ethnic structure of the United States,Professional football in the United States is almost wholly played by native-born Americancitizens, mostly very
45、large and very strong, many of them black. It is a game of physical strength. Linemen routinely weigh more than 300 pounds.

Baseball was once Americas favorite game, but has lost that claim to basketball.Baseball is a game that requires strength, but not hugeness. Agility, quickness, perfect vision and qui

In that Sundays final, the final hit of the extra inning game was delivered by a native of Columbia. The Most Valuable Player in the game was a native of Columbia
48、. The rosters of both teams were awash with Hispanic names, as is Miami, which now claims the World Championship is a game that may be losing popularity in America, but has gained it in much of the rest of the world. Baseball in America has taken on a strong Hispanic flavor, with a dash of Japanese added for seasoning.Soccer, which many countries just call football, i
