12、you haven“t encoded it deeply.“ Encoding, Schacter explains, is a special way of paying attention to an event that has a major impact on recalling it later. Failure to encode properly can create annoying situations. If you put your mobile phone in a pocket, for example, and don“t pay attention to wh

13、at you did because you“re involved in a conversation, you“ll probably forget that the phone is in the jacket now hanging in your wardrobe. “Your memory itself isn“t failing you,“ says Schacter. “Rather, you didn“t give your memory system the information it needed.“ Lack of interest can also lead to

14、absent-mindedness. “A man who can recite sports statistics from 30 years ago,“ says Zelinski, “may not remember to drop a letter in the mailbox.“ Women have slightly better memories than men, possibly because they pay more attention to their environment, and memory relies on just that. Visual cues c

15、an help prevent absent-mindedness, says Schacter. “But be sure the cue is clear and available,“ he cautions. If you want to remember to take a medication with lunch, put the pill bottle on the kitchen tabledon“t leave it in the medicine chest and write yourself a note that you keep in a pocket Anoth

16、er common episode of absent-mindedness: walking into a room and wondering why you“re there. Most likely, you were thinking about something else. “Everyone does this from time to time,“ says Zelinski. The best thing to do is to return to where you were before entering the room, and you“ll likely reme

18、possible reason why women have better memories than men is that _.（分数：5.00）A.they have a wider range of interestsB.they are more reliant on the environmentC.they have an unusual power of focusing their attentionD.they are more interested in what“s happening around them(3).A note in the pocket can ha

Attaching radio devices to it is difficult, and visual sightings are too unreliable to

22、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 Navy“s formerly top-secret system of underwater listening devices sp

23、anning 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 the ships of potential enemies. Earth

24、 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 currents and measuring changes in ocean an

25、d global temperatures. The speed of sound in water is roughly one mile a secondslower 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 stethoscope does when it carries faint noises f

26、rom a patient“s chest to a doctor“s 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：25.00）(1).The passage is chiefly about _.（分数：5.00）A.an effort to protect an endangered marine speciesB.the c

27、ivilian use of a military detection systemC.the exposure of a U.S. 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：5.00）A.to trace and locate enemy vesselsB.to monitor deep-sea volcanic eruptionsC.to study th

28、e movement of ocean currentsD.to replace the global radio communications network(3).The deep-sea listening system makes use of _.（分数：5.00）A.the sophisticated technology of focusing sounds under waterB.the capability of sound to travel at high speedC.the unique property of layers of ocean water in tr

29、ansmitting soundD.low-frequency sounds traveling across different layers of water(4).It can be inferred from the passage that _.（分数：5.00）A.new radio devices should be developed for tracking the endangered blue whalesB.blue whales are no longer endangered with the use of the new listening systemC.opi

30、nions 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 U.S. Navy underwater listening network?（分数：5.00）A.It is now partly accessible to civilian scientists.B.It h

31、as been replaced by a more advanced system.C.It became useless to the military after the cold war.D.It is indispensable in protecting endangered species.The fitness movement that began in the late 1960s and early 1970s centered around aerobic exercise. Millions of individuals became engaged in a var

32、iety of aerobic activities, and literally thousands of health spas developed around the country to capitalize on this emerging interest in fitness, particularly aerobic dancing for females. A number of fitness spas existed prior to this aerobic fitness movement, even a national chain with spas in mo

33、st major cities. However, their focus was not on aerobics, but rather on weight-training programs designed to develop muscular mass, strength, and endurance in their primarily male enthusiasts. These fitness spas did not seem to benefit financially from the aerobic fitness movement to better health,

34、 since medical opinion suggested that weight-training programs offered few, if any, health benefits. In recent years, however, weight training has again become increasingly popular for males and for females. Many current programs focus not only on developing muscular strength and endurance but on ae

35、robic fitness as well. Historically, most physical-fitness tests have usually included measures of muscular strength and endurance, not for health-related reasons, but primarily because such fitness components have been related to performance in athletics. However, in recent years, evidence has show

36、n that training programs designed primarily to improve muscular strength and endurance might also offer some health benefits as well. The American College of Sports Medicine now recommends that weight training be part of a total fitness program for healthy Americans. Increased participation in such
