三、阅读理解(共两节，满分35分)
第一节(共15小题；每小题2分，满分30分)
A [2022·安徽]
A team of scientists are carrying out a project at the University of Greenwich in London. They are trying to find ways to make food on Mars (火星) in the future. The project is called Feeding Mars. It tries to use water, fish and fish waste to grow fruit and vegetables on Mars.
It would take at least 21 months to reach Mars, learn about its surface and return to Earth. So it would be a big help if the spacemen could grow fresh food on Mars itself.
Farming on Mars, however, will be very hard. There’s plenty of water th at could be taken from ice just below the surface, but the land on Mars is missing the nutrients (养分) that living things need. The team says that they could solve the problem by growing plants and fish together. Fish waste can then be used to provide nutrients for plants.
“It is expected that you can grow lots of food, such as vegetables, salads, teas and medicinal plants on Mars,” said Dr Benz Kotzen, who leads the project. “You can even harvest (捕获) fish for food then.”
31. What does the underlined word “It” in Paragraph 1 refer to (指的是)?
A. The future.
B. The project.
C. The land.
D. The planet.
32. What makes it difficult to farm on Mars?
A. Ice below the surface.
B. Too much fish waste.
C. The missing of living things.
D. The poor land condition.
33. How does Dr Benz Kotzen feel about Feeding Mars?
A. Hopeful.
B. Doubtful.
C. Surprised.
D. Funny.
B [2022·云南改编]
Wukong, Tiangong, Tianwen… Do you know where the names of Chinese space programs come from?
Wukong, the Dark Matter Particle Explorer satellite (暗物质粒子探测卫星), is named after Chinese superhero Monkey King. According to J ourney to the West, Monkey King has a pair of sharp eyes which can tell the difference between good and evil. The Wukong satellite is just as sharp-eyed as Monkey King to help scientists search for dark matter in space.
The name of the space station, Tiangong, means “Heavenly Palace”. In Chinese myths (神话), this is the home of Tian Di. Now Tiangong Space Station is a home for Chinese astronauts in space. And China welcomes foreign astronauts to Tiangong so that they can work together.
Tianwen, China’s Mars missions (任务), gets its name from the poem Tianwen by Qu Yuan. Qu Yuan is a well-known poet from ancient China. In Tianwen, he had the questions about the sky, stars, nature, myths and the real world, showing his hunger for truth. Perhaps the Tianwen missions will end up answering some of Qu Yuan’s questions.
If you look into more names of Chinese space programs, you will find that they all have beautiful meanings. We, the Chinese people, have a long-cherished (珍藏已久的) space dream. So the naming of Chinese space programs is taken very seriously.
34. What is the Wukong satellite used for?
A. Answering some of Qu Yuan’s questions.
B. Finding the difference between good and evil.
C. Helping scientists search for dark matter in space.
D. Welcoming foreign astronauts to the space station.
35. The name of China’s Mars missions is from ________.
A. Qu Yuan’s poem Tianwen
B. an ancient novel
C. ancient Chinese myths
D. Journey to the West
36. Why do we take the naming of Chinese space programs seriously?
A. We want to land on Mars.
B. We want to protect the Earth.
C. We have the hunger for truth.
D. We have a dream for space.
37. Which can be the best title for the passage?
A. What Beautiful Names
B. What a Cherished Star
C. What Excellent Poems
D. What a Long Journey
C【2022·金华】
Many people may wonder what the three Chinese astronauts’ life was like when they were working in space. In fact, they did many of the things as we do on Earth.
They brush their teeth, wash their hair and go to the bathroom. However, because of the microgravity (失重) environment, they take care of themselves in different ways. They wash their hair by using the no-rinse shampoo to get it clean because there are no real showers in the spaceship.
Astronauts eat three meals a day: breakfast, lunch and dinner. But how much they eat depends on the astronauts. A small woman astronaut often needs only about 1,900 calories (卡路里) a day, while a large man requires about 3,200 calories. So there are
many kinds of foods ready, such as fruits, nuts, chicken, beef and seafood. They can also drink coffee, tea and orange juice.
Astronauts can have much fun, too. They look out of the window, enjoying the wonderful sunsets and sunrises which happen every 45 minutes. Very often, they play with their food or even play jokes on their workmates. Believe it or not, astronauts can even spend weekends, when they can watch movies, play music, read books and talk to their families.
After a long day at work, ▲. Just like on Earth, an astronaut goes to bed at a certain time, then wakes up and prepares for work again. But there are a few differences. Astronauts have to sleep in sleeping bags in special cabins (柜子). Generally, astronauts are planned to have eight hours of sleep. Like on Earth, they may wake up in the middle of their sleep to use the toilet. And astronauts also have dreams.
As for Wang Yaping, she had another experience—preparing for lessons for the Chinese students far down on Earth.
38. The passage mainly talks about ________.
A. how astronauts work in space
B. what it is like inside a spaceship
C. what kind of people can be astronauts
D. astronauts’ daily life in the spaceship
39. From the passage we can learn that astronauts ________.
A. have to take showers every two days
B. are not allowed to play jokes in space
C. can have many kinds of foods for their meals
D. seldom have dreams when they sleep in space
40. Which of the following can be put in the ▲in Paragraph 5?
A. it is time to make a phone call
B. reading is what an astronaut needs
C. listening to music sounds like a good idea
D. nothing is better than a good night’s sleep
41. What was Wang Yaping’s special experience in space?
A. Making different kinds of foods.
B. Taking care of the other astronauts.
C. Writing a report about space travel.

A Guide to Living on Jupiter
As we know, there is no life on Jupiter now. But by the year 2300, we might move to Jupiter. Here is a guide to living on Jupiter.
The weather on Jupiter is very cold. We would wear special clothes to keep warm. We would eat dried food. It wouldn’t get bad, but it wouldn’t be delicious. We would live in big rooms and have much space. The transport on Jupiter would be better than that on the Earth. There would be fewer people. The high-speed electronic trains could arrive everywhere. We could go anywhere easily. We would use Jupiter money. And everything would be expensive, because everything must be taken from the Earth. But we could work to get much money.
The life on Jupiter would be wonderful. Would you like to move there?
作文点评：本文采用“三步法”畅想人们在木星上的生活状况。

首先引出话题，人们可能在2300 年移居木星；接着围绕衣、食、住、行等方面介绍在木星上的生活状况，这样使得文章层次分明；最后作者用一个形容词wonderful 和一个疑问句，希望激发人们对在木星上生活的向往。

添彩点：文中画线词句是本文的添彩点。
