[限时检测] (限时30分钟) Ⅰ.阅读理解 A (2022·枣庄二模)Space tourism is the term used to describe space travel for recreational or leisure purposes.What was once only a dream，as described in A Space Odyssey by Arthur C．Clarke，is now becoming a reality. Futurologists attempt to make predictions of what life will be like in the future.After the first man landed on the moon，they thought that hotels would be built on the moon by the year 2000.They also considered the possibility that，in the 21st century，families might go for a holiday on the moon.Neither of these predictions have come true yet—but the rapid development of technology may mean these predictions are possible in the years to come. Space Adventures is currently the only company to have succeeded in sending paying passengers into space.It worked with the Federal Space Agency of Russia and Rocket and Space Corporation Energia to provide flights for the world's first private space explorers.Each paid over $20 million for their 10­day trip to the International Space Station. Following successful explorations into space，other companies are now considering the possibility of enabling tourists to visit space.To make it affordable，suborbital space travel is being considered by some companies，like Virgin Galactic.Passengers would be transported to a height of between 100 and 160 km above earth，experience 3－6 minutes of weightlessness and a view of the stars before back to earth.This is expected to cost around $200，000 per person. Whilst it could be an enriching experience，there are some disadvantages.Many critics say that a huge growth in the spaceflight industry could drastically speed up the process of global warming.The ozone layer would be damaged further and the polar regions would suffer.In addition，space travel is only really affordable for the super­rich，though Virgin Galactic claims to be ‘opening space to the rest of us’． 【解题导语】　本文是一篇说明文。文章主要说明了太空旅行发展的可能性及其可能会带来的问题。 1．What do you know about space tourism?
