1 结合下面材料，回答问题。应用GIS解决公交塞车问题为了解决公交车、出租车的违章行为，广州市交警部门开展了公交车行车秩序的专项整治。严格规定了公交车和出租车在不同情况下停车与下客的行驶路线和停靠方式。对于公交车、出租车驾驶员违规，交警部门制定了严格的处罚措施。因为整治，司机们都规规矩矩地排队进站，但没有预料到的是在天河城、黄埔大道、岗顶等公交线路密集路段一度出现了大塞车。问题最突出的路段，在下班高峰时，公交长龙一直从体育中心站排到了天河立交桥。后来发现，公交车按规矩进站反而出现了塞车的怪现象，原因是广州市一些道路站点和线网设置不合理，如在广州市一些主干道上，有些公交站有十几条、二十条线路，大量公交车挤在同一个站上下客。为了解决这个问题，广州市交通部门一方面制定了市区公交线路密集段的站点调整方案，另一方面又推出了“公交地理信息系统”。该系统建立在电子地图的基础上，使公交车重登率、换乘系数等运行状况一目了然。交通管理部门根据该系统提供的数据进行综合分析，采用了将有些站点易位、增设公交站点以及在一些主干道上设置公交专用道（公交快车走廊）等措施，有效地扭转了该市公交塞车的局面。（1）目前GIS在城市建设和管理中的典型应用有哪些方面? （2）你所在城市在城市管理中是否有可以运用CIS帮助改善管理状况的情况?你能否借鉴材料中的经验谈一下改进意见?

5 阅读理解。 Driving to a friend"s house on a recent evening, I was attracted by the sight of the full moon rising just above my friend"s rooftops. I stopped to watch it for a few moments, thinking about what a pity it was that most city people, myself included, usually miss sights like this because we spend most of our lives indoors. My friend had also seen it. He grew up living in a forest in Europe, and the moon meant a lot to him then. It had touched much of his life. I know the feeling. Last December I took my seven-year-old daughter to the mountainous jungle of northern India with some friends. We stayed in a forest rest-house with no electricity or running hot water. Our group had campfires outside every night, and indoors when it was too cold outside. The moon grew to its fullest during our trip. Between me and the high mountains lay three or four valleys. Not a light shone in them and not a sound could be heard. It was one of the quietest places I have ever known, a bottomless well of silence. And above me was the full moon, which struck me deeply. Today our lives are filled with glass, metal, plastic and fibre-glass. We have televisions, cell phones, pagers, electricity, heaters and ovens and air-conditioners, cars, computers. Struggling through traffic that evening at the end of a tiring day, most of it spent indoors, I thought: before long, I would like to live in a small cottage. There I will grow vegetables and read books and walk in the mountains And perhaps write, but not in anger. I may become an old man there, and wear the bottoms of my trousers rolled and measure out my life in coffee spoons. But I will be able to walk outside on a cold silent night and touch the moon. 1.The best title for the passage would be______. A. The pleasures of modern life B. Touched by the moon C. A bottomless well of silence D. Break away from modern life 2. What impressed the writer most in the mountainous jungle of northern India? A. The nice moonlight B. Complete silence. C.
