The search for life in the universe took a step forward last month with the opening of the Allen Telescope Array(艾伦望远镜阵列) in Hat Creek, California. The telescopes were partly made possible by a gift of twenty-five million dollars from Paul Allen. The total cost of the project is already fifty million dollars.
At present, there are 42 radio telescopes working at the Hat Creek observatory. The signals they receive are combined to create what is equal to a single, very large telescope. The telescope will be used to observe objects like exploding stars, black holes and other objects that are predicted but have not yet been observed. Seth Shostak of the SETI Institute says this is the first telescope whose main purpose is to search for signals from intelligent life in space. The SETI Institute is based in Mountain View, California. The organization supports the search for other life forms in the universe.
What makes the Allen Telescope Array unusual is that it can collect and study information from a wide area of the sky. In addition, the 42 telescopes can study information about several projects at the same time. That means studies of large areas of the sky can be made faster than ever before.
Some officials think the Allen Telescope Array will be completed in three more years. 350 individual radio telescopes are planned. The new abilities of the Allen Telescope Array will make searching for stars similar to the sun much faster.
An earlier search by SETI, Project Phoenix, studied about 800 stars to a distance of 240 light years. The project ended in 2004. With the Allen Telescope Array, astronomers hope to gather thousands of times more information in the search for life beyond our planet.
【小题1】The main purpose of the Allen Telescope Array is .A.to serve for the research of weather predicationB.to prepare for the wars against life from the universeC.to search for signals from intelligent life in spaceD.to observe exploding stars, black holes and other objects【小题2】From this passage we know that .A.the 42 radio telescopes at Hat Creek observatory can work togetherB.the total cost of the project came from Paul AllenC.Hat Creek observatory can receive signals from all parts of the wormD.Hat Creek observatory is operated by an American named Paul Allen【小题3】Which of the following is TRUE according to this passage?A.The Allen Telescope Array takes much more room than former telescopes.B.The Allen Telescope Array is still being built at present in the United States.C.Another 42 radio telescopes will be fixed in the Allen Telescope Array.D.The SETI Institute is against the search for other life forms in the universes.【小题4】With the help of the Allen Telescope Array, .A.astronomers can gather more information than before from other planetsB.humans will have more chances to live on other planets than beforeC.humans will be able to find more natural resources on other planetsD.scientists will be able to find more natural resources from other planetsC
最佳答案
(答案→)C 解析:本文介绍了the Allen Telescope Array(艾伦望远镜阵列)的具体情况。【小题1】C 推理题。根据第一段1,2行he search for life in the universe took a step forward last month with the opening of the Allen Telescope Array(艾伦望远镜阵列) in Hat Creek, California.可知这个望远镜阵列主要就是为了观察太空里的生命迹象的,故C正确。【小题2】A 细节题。根据第二段2,3行In addition, the 42 telescopes can study information about several projects at the same time.可知他们可以同时工作,故A正确。【小题3】B 推理题。根据最后一段1,2行Some officials think the Allen Telescope Array will be completed in three more years.可知现在它还没有被建好,还正在被建。故B正确。【小题4】A 细节题。根据文章最后一句With the Allen Telescope Array, astronomers hope to gather thousands of times more information in the search for life beyond our planet.可知A正确。
