Part2 阅读综合练习 四、阅读理解 Are you interested in the idea of space travel? More than ever before, it is becoming a reality. In 2021, two people flew into space aboard the spacecraft developed by their own respective companies. When explaining the importance of space travel, one told the media that many people are not “fully educated as to what space does for the Earth”.He said that we need more rocketships going into space because they can help us to know more about things like climate change. “We have to build a road to space so that the younger generation and their kids can build a future,” the other said. He added that space tourism is the first step toward moving people (and heavy industry) into space to prevent an energy crisis on the Earth. But some people have different opinions. They think it is part of the so-called “billionaire space race”, which offers what’s seen by some as “joyrides” to the super-wealthy. According to Forbes, one open seat on the rocket going to space was sold for $28 million at auction ( 拍卖) in June. “A lot of people believe there is a market for space tourism, but right now it’s at the very high end,” McCurdy, a space policy expert in the UK, told a website. “If we’re going into space, who’s the ‘we’? Is it just the top 1 per cent of the top 1 per cent?” So with the sky-high prices, should ordinary people give up the dream of space exploration? Maybe not. The US flight engineer Jason said that we are at the point at which space tourism is a privilege ( 特权) preserved for the super-rich, but that doesn’t mean the trend will last forever. He predicted that the price will come down. “Maybe in 10 to 15 years, it’s a decision between ‘do I buy a new car’ and ‘do I go into space’. We should invest in a future that allows us to live somewhere else.” 1. ( )What does the underlined word “crisis” mean in this passage? A. A big chance. B. A bad situation. C. A special type. D. A power station. 2. ( )What do the two people who flew into space think of space tourism? A. It is too dangerous for humans. B. It is meaningful to the future generations. C. It is a privilege for the super-wealthy. D. It may cause problems like climate change. 3. ( )If there will be, what might be the next timeline according to the passage? A. 2030s Space tourism: Joyrides for all. B. 2020s Space tourism: Joyrides for private citizens. C. 2030s Not only the super-rich went into space. D. 2020s The public enjoyed space exploration. 4. ( )Which of the following is NOT mentioned in the passage? A. The first non-government astronaut from the USA went into space in the late 20th century. B. People with different opinions think the market for space tourism is at the very high end. C. The price of flying into space has been cut down. D. Two people were sent into space with their own spacecraft. Part 3 Reading II Part1 基础知识过关练 一、从方框中选择适当的单词并用其正确形式填空 ( taste planet increase rapid pollute ) 1.

On October 24, Deep Blue Aerospace, a Chinese space company, sold two space travel tickets in a livestream. This was China’s first try of selling space tickets. The tickets were priced at 1.5 million yuan each. But during the live stream, they were just 1 million yuan each. The 12-minute space trip will give a different experience. According to the company, passengers will sit in a spacecraft that is about 4 meters tall and 3. 5 meters wide, with six big windows and space for six people. The spacecraft will go 100 kilometers above the Earth. Travelers will experience weightlessness (失重) for at least five minutes and see the Earth from above before coming back down safely. Passengers between 18 and 60 years old can be chosen. And of course they should be healthy. After being chosen, they have to take some security training before the trip. The trip will use the company’s Nebula-rocket. It runs on oxygen and kerosene (煤油) and can be reused. With the development of modern technology, space tickets might become less expensive, said Huo Liang, CEO of Deep Blue Aerospace. The company plans to do lots of tests in 2026 to make sure the space trip is safe. They hope to begin the trip in 2027. 回答下面5 个问题，每题答案不超过6 个词。 1.
