Passage 18

(山东省兖州市2009届高三高考仿真考试C篇)

It is hard to go after the blue whale, the ocean’s largest creature, which has almost been killed off by commercial whaling and is now listed as an endangered species. Attaching radio devices to it is difficult, and sightings with bare eyes 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 Navy’s formerly top-secret system of underwater detecting(探测)devices across the oceans.　

Tracking whales is but one example of an exciting new world just opening to civilian(平民的)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(潜在的)enemies.　

Earth scientists announced at a news conference recently that they had used the system for closely monitoring a deep-sea volcanic eruption(爆发)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 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 stethoscope(听诊器)does when it carries faint noises from 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.

Passage 17

(山东省兖州市2009届高三高考仿真考试B篇)

A new study suggests that the more teenagers watch television, the more likely they are to develop depression(沮丧；抑郁)as young adults.　

The researchers used a national long-term survey of adolescent health to investigate (调查)the relationship between media use and depression. They based their findings on more than four thousand adolescents who were not depressed when the survey began in 2000.　

As part of the survey,　 the young people were asked how many hours of television or videos they watched daily. They were also asked how often they played computer games and listened to the radio. Media use totaled an average of five and one-half hours a day. More than two hours of that was spent watching TV.　

Seven years later, in 2007, more than seven percent of the young people had signs of depression. The average age at that time was twenty-one.　

The researchers say they did not find any such relationship with the use of other media such as movies, video games or radio, etc. But the study did find that every extra hour of television meant an eight percent increase in the chances of developing signs of depression. Young men were more likely than young women to develop depression given the same amount of media use.　

The study didn’t explore if watching TV causes depression. But one possibility is that it was taking time away from activities that could help prevent depression.　

Last December, the journal Social Indicators Research published a study of activities that help lead to happy lives. Sociologists from the University of Maryland found that people who describe themselves as happy spend less time watching television than unhappy people. The study found that happy people are more likely to be socially active to read, to attend religious services and to vote.
