As part of an event called the Great World Wide Star Count, adults and kids looked for one of two constellations (星座) Cygnus in the Northern Hemisphere and Sagittarius in the Southern Hemisphere. The observers recorded how many stars they saw and how bright the stars were, and then posted their results online.The Star Count was part of a global effort to help scientists learn more about how light pollution affects our view of the night sky. Whether participants saw thousands of stars or just a dozen depended a lot on whether they were surrounded by darkness or by twinkling city lights.On a clear night, with no clouds, moonlight, or artificial lights to block the view, people can see more than 14,000 stars in the sky, but when people are surrounded by city lights they're lucky to see 150 stars.If you've ever driven toward a big city at night and seen its glow from afar, you've witnessed light pollution. It occurs when light from streetlights, office buildings, signs, and other sources streams into space and illuminates the night sky. This light makes many stars invisible to people on earth.Dust and particles of pollution from factories and industries worsen the effects of light pollution. When these particles float into the atmosphere, light ricochets (跳飞) off of them and scatters even more.Light pollution doesn't only affect star visibility. It can harm wildlife too. Scientists don't entirely understand how animals navigate at night, but it's clear that artificial light can attract them, making them go off course. There's increasing evidence, for example, that migrating birds use sunsets and sunrises to help find their way.1Why do many people look at the local sky?ATo enjoy the beauty of the stars.B. To develop their interest in Astronomy.C. To help scientists do a research on light pollution.D. To get the exact number of stars in the sky.答案与解析C细节理解题。根据第一段最后一句和第二段第一句可知，他们参加 the Great World Wide Star Count活动的目的是帮助科学家更深入地了解光污染在夜晚对人们视野的影响。2When people are surrounded by artificial lights, _.Athey can find more stars in the skyB. the stars might appear more clearlyC. the stars seem to be biggerD. they can find far fewer stars答案与解析D推理判断题。根据第三段可知，正常情况下人们能看到14000颗星星，但是在有人造光时只能看到150颗，所以要少得多。3The following things make light pollution worse EXCEPT _.Aartificial lights B. starsC. dust D. particles答案与解析B细节理解题。根据第三段中artificial lights和第五段第一句可排除B项。4How does light pollution affect birds?AIt does great harm to their eyes at night.B. It misleads them the way when they migrate.C. It can enable them to see their routes clearly.D. It can make them find their way easily.答案与解析B推理判断题。根据最后一段可知，人造光吸引鸟类，使它们偏离飞行路线。.阅读理解七选五How to Make FriendsFriendship is a very important human relationship and everyone needs good friends.

First of all, there aren't enough stops in the streets. And taxis often run very fast, which caused many traffic accidents. Additional, some taxi drivers refuse to pick some passengers without any reason. Another terrible thing is that deeply at night taxis waiting around entertainment places make too much noise. A friend of mine living in another city once visited to me, and she told me a taxi driver once cheated her by taking a roundabout route. How will a guest think of our city after such bad experience? I think we must take actions to tighten control over the taxi trade. The last thing to do is raise the taxi drivers' professional morality.Sincerely yours，Chris答案Dear Mayor, I'm a resident of the city. I feel there are many problems in the trade of taxis in our city.
