Question

阅读理解 　　Have you ever dreamed of visiting a planet in the Milky Way(银河系)?While the trip sounds exciting, it would take years and years to reach your destination．So in the future, bedtime for astronauts may be more than a few hours of regular shut eye．They would have to sleep for years． 　　European researchers are now conducting hibernation experiments．The study may help them understand whether humans could ever sleep through the years it would take for a spaceflight to distant planets．“If there was an effective technology, it could make deep-space travel a reality,”said Mark Ayre of the European Space Agency last month． 　　What seems like a science fiction is not completely unlikely．Researchers have been able to use chemicals to put living cells into a sleep-like state where they don't age．They have now moved on to the small, non-hibernating mammals(哺乳动物)like rats． 　　A major challenge is the fact that cells can be very simple systems, whereas body organs are far more complex(复杂的)．“It's like moving from a simple Apple computer to a supercomputer,”said Marco Biggiogera, a hibernation researcher at Italy's University of Pavia．Just like bears and frogs, the hibernation of human beings would cause a person's metabolism(新陈代谢)to lower so they would need less energy． 　　Medical research, however, is just half of a spaceflight hibernation system．There is a challenge of designing a suitable protective shelter(栖身所)．Such a shelter would provide the proper environment for hibernation, such as the proper temperature．It would also have to monitor(监控)life functions and serve the physiological needs of the hibernator． 　　According to Ayre, the six-person Human Outer Planets Exploration Mission(使命)to Jupiter's moon(木星的卫星)Callisto, could be an opportunity to use human hibernation．The mission aims to send six persons on a five-year flight to Callisto, where they will spend 30 days, in 2045． (1) According to the article, the hibernation research ________． [　　] A． is just an idea B． is always a science fiction C． has already finished successfully D． has made some progress (2) In a hibernating state, a person needs ________． [　　] A． less sleep B． more food C． less energy D． more movement (3) The first try of the hibernation technologythe six-person Human Outer Planets Exploration Mission to Jupiter's moon Callisto． [　　] A． will be B． has been planned for C． is certain to be D． may be (4) What is the best title of the article? [　　] A． Hibernation study for space travel B． Welcome to our space travel C． To hibernate, to live longer D． Welcome to the Milky Way

Answer 1

答案：1．D;2．C;3．D;4．A;
解析：

(1)	推理判断题。由原文第三段可以推出答案。
(2)	细节判断题。由原文第四段的最后一句可知。
(3)	推理判断题。由原文最后一段的第一句话中could一词的委婉语气可推出答案。
(4)	星际探索固然重要，可是怎样打发漫漫旅途呢？别急，人类“冬眠”技术让你一觉睡到目的地。 　　结构层次：星际探索旅途遥远，漫长的时间难以打发；欧洲科学家正在研制“冬眠”技术；科学家们需要解决两个问题：降低太空人的新陈代谢速度；给太空人提供理想的栖身处。 　　标题判断题。认真分析原文可知，本文自始至终介绍的是在星际探索中使用冬眠技术的研究情况，因此以Hibernation study for space travel为题既具有高度的概括性、强烈的针对性，又具有一定的醒目性。
