阅读理解 Astronauts on shorter shuttle missions often work very long days. Tasks are scheduled so tightly that break times are often used to finish the day's work. This type of schedule is far too demanding for long missions on the International Space Station (ISS). ISS crewmembers usually live in space for at least a quarter of a year. They work five days on and two days off to mimic the normal way they do things on Earth as much as possible. Weekends give the crew valuable time to rest and do a few hours of housework. They can communicate with family and friends by email, internet phone and through private video conferences.While astronauts cannot go to a baseball game or a movie in orbit, there are many familiar activities that they can still enjoy. Before a mission, the family and friends of each ISS crewmember put together a collection of family photos, messages, videos and reading material for the astronauts to look at when they will be floating 370 kilometers above the Earth. During their mission, the crew also receives care packages with CDs, books, magazines, photos and letters. And as from early 2010, the internet became available on the ISS, giving astronauts the chance to do some web surfing in their personal time. Besides relaxing with these more common entertainments, astronauts can simply enjoy the experience of living in space.Many astronauts say that one of the most relaxing things to do in space is to look out the window and stare at the universe and the Earth. Both the shuttle and the ISS circle the planet several times each day, and every moment offers a new view of the Earth's vast land mass and oceans1.What does the word mimic in Paragraph 1 probably mean?A.copyB.findC.changeD.lose2.Which of the following best describes the families of the astronauts on the ISS?A.They are impatient and annoyedB.They are worried and upsetC.They are caring and thoughtfulD.They are excited and curious3.In the final paragraph, the author shows that astronauts ________A.love to see the Earth from spaceB.find living in space a bit boring and tiringC.regard space life as commonD.get more pleasure in space than on the Earth4.The passage mainly discusses how astronauts ________A.work for longer missions in spaceB.spend their free time in spaceC.observe the Earth from spaceD.connect with people on the Earth

ACAB解析试题分析：本文向我们介绍了宇航员在太空中是如何打发他们的自由利用的时间的。1.这是词义猜测题。根据根据第一段第四句“They work five days on and two days off”可知，这和在地球上的工作时间一致，所以这样做的目的是尽可能地模仿地球上的正常生活，所以选A。2.这是推理判断题。根据根据第二段第二句“Before a mission, the family and friends of each ISS crewmember put together a collection of family photo, messages, videos and reading material for the astronauts to look at when they will be floating…可知，宇航员的家人是体贴的，考虑周到的。故选C。3.这是细节理解题。根据第三段“the most relaxing things to do in space is to look out the window and stare at the universe and the Earth.”可知，宇航员喜欢在太空看地球。故选A。4.这是主旨大意题。根据本文主要向我们介绍了宇航员在休息时做的事，所以选B。考点：这是一篇说明文。点评：说明文、议论文类文章：文章的主题句往往出现在首段或末段。第一段给出作者的观点或引出将要介绍的事物，而末段则总结全文、重申论点。因此，在阅读议论文或说明文时，一定要注意首段或末段的信息，因为那通常就是文章的主题句。

谢谢了
