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.

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.

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.

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.

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

42、e use of the new listening systemC.opinions differ as to whether civilian scientists should be allowed to use military technologyD.military technology. has great potential in civilian use(5).Which of the following is true about the Navy underwater listening network?（分数：1.00）A.It is now partly access

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.
