单选题Which of the following statements can best describe the main theme of the passage?

单选题{{B}}Passage Five{{/B}} It used to take Redwood City, California police hours to locate gunfire. Now, they have a new tool that helps them find the gunfire quickly. This new tool is called the ShotSpotter. The police began using the ShotSpotter in 1995. They wanted to cut down on gunfire in their city. One ShotSpotter covers a square mile. Eight microphones are put on the roofs of buildings. These microphones pick up gunfire noise. It only takes seven seconds to report the gunfire to the police. Then a red dot on the police map shows where the action is. The ShotSpotter really works well. It locates the gunfire within 20 to 40 feet plus or minus. Redwood City police are very happy with the ShotSpotter. They think it might have helped catch the D.C. sniper. ShotSpotters cost a lot of money. One of them sells for $200,000. Despite the cost, ShotSpotters can be a big help in fighting crime.

单选题The tree people in the Lord of the Rings—the Ents—can get around by walking. But for real trees, it's harder to uproot. Because they're literally rooted into the ground, they are unable to leave and go 24 . When a tree first starts growing in a certain area, it's likely that the 25 envelope—the temperature, humidity, rainfall patterns and so on—suits it. Otherwise, it would be unable to grow from a seedling. But as it 26 , these conditions may change and the area around it may no longer be suitable for its 27 . When that happens, many trees like walnuts, oaks and pines, rely 28 on so-called 'scatter hoarders,' such as birds, to move their seeds to new localities. Many birds like to store food for the winter, which they 29 retrieve. When the birds forget to retrieve their food—and they do sometimes—a seedling has a chance to grow. The bird Clark's nutcracker, for example, hides up to 100,000 seeds per year, up to 30 kilometers away from the seed source, and has a very close symbiotic (共生的) relationship with several pine species, most 30 the whitebark pine. As trees outgrow their ideal 31 in the face of climate change, these flying ecosystem engineers could be a big help in 32 trees. It's a solution for us—getting birds to do the work is cheap and effective—and it could give 33 oaks and pines the option to truly 'make like a tree and leave.'

单选题Education is one of the key words of our time. A man, without an education, many of us believe, is an unfortunate victim of adverse circumstances deprived of one of the greatest twentieth-century opportunities. Convinced of the importance of education, modern states "invest" in institutions of learning to get back "interest" in the form of a large group of enlightened young men and women who are potential leaders. Education, with its cycles of instruction so carefully worked out, is punctuated by textbooks--those purchasable wells of wisdom--what would civilization be like without its benefits? So much is certain: that we would have doctors and preachers, lawyers and defendants, marriages and births; but our spiritual outlook would be different. We would lay less stress on "facts and figures" and more on a good memory, on applied psychology, and on the capacity of a man to get along with his fellow citizens. If our educational system were fashioned after its bookless past we would have the most democratic form of "college" imaginable. Among the people whom we like to call savages all knowledge inherited by tradition is shared by all; it is taught to every member of the tribe so that in this respect everybody is equally equipped for life. It is the ideal condition of the "equal start" which only our most progressive forms of modem education try to regain. In primitive cultures the obligation to seek and to receive the traditional instruction is binding to all. There are no "illiterates"--if the term can be applied to people without a script--while our own compulsory school attendance became law in Germany in 1642, in France in 1806, and in England 1876, and is still non-existent in a number of "civilized" nations. This shows how long it was before we deemed it necessary to make sure that "all our children could share in the knowledge accumulated by the "happy few" during the past centuries. Education in the wilderness is not a matter of monetary means. All are entitled to an equal start. There is none of the hurry which, in our society, often hampers the full development of a growing personality. There, a child grows up under the ever-present attention of his parents, therefore the jungles and the grasslands know of no "juvenile delinquency". No necessity of making a living away from home results in neglect of children and no father is confronted with his inability to "buy" an education for his child.
