This is the sixth such storm found on the icy giant planet in the past 3___ decades. Neptune is the eighth planet from the Sun. It is famous for its deep blue color and extremely cold temperatures. The new storm is huge—about 4,800 kilometers wide, nearly the size of the Atlantic Ocean. It appears as a dark spot because it is a hole in the clouds, showing deeper layers of the atmosphere. Unlike storms on Earth, Neptune’s dark storms spin in the opposite direction. They are high-pressure systems, while Earth’s hurricanes are low-pressure. Scientists believe these storms form deep inside Neptune’s atmosphere, where it is warmer, and then rise to the top. The storm moves at speeds of up to 1,200 kilometers per hour, much faster than any storm on Earth. Why is this discovery important? First, it helps scientists understand Neptune’s atmosphere. The storm’s movement shows how heat and gases move inside the planet. Second, it gives clues about weather on other gas giants, like Jupiter and Saturn. Third, studying Neptune helps us learn about planets outside our solar system, called exoplanets. Dr. Sarah, who led the research, said, “Neptune is a mysterious planet. We still know very little about it. This storm tells us that its atmosphere is very active.” She added, “We will keep watching this storm to see how it changes. Storms on Neptune usually last for about 2 years before disappearing.” The discovery reminds us that our solar system is full of surprises. Even after hundreds of years of studying planets, there is still much to learn. As technology improves, we will uncover more secrets of the universe. 21. What is special about the new storm on Neptune? A. It is the first storm found on Neptune. B. It spins in the opposite direction of Earth’s storms. C. It is caused by human activities. D. It lasts for more than 10___ years. 22. 特色考法·词汇指代题 What does the underlined word “it” in Paragraph 3 refer to? A. Neptune. B. The new storm. C. The Hubble Space Telescope. D. The Atlantic Ocean. 23. How long do storms on Neptune usually last? A. About 1 year. B. About 2 years. C. About 3decades. D. More than 10 years. 24. What can we learn from the passage? A. Neptune is the warmest planet in the solar system. B. The new storm is smaller than the Atlantic Ocean. C. Studying Neptune helps scientists understand other planets. D. Dr. Sarah discovered five storms on Neptune before this one. 25. What is the best title for the passage? A. The Blue Planet: Neptune B. A New Storm Found on Neptune C. How to Use the Hubble Space Telescope D. Weather on Earth vs. Weather on Neptune Ⅴ. 阅读表达 阅读下面短文，根据短文内容回答问题。 I am standing on a quiet hill on Mars. The sky is a pale orange, and the twin suns of our colony are setting slowly. Below me, I see the dome-shaped houses where families live. Children are playing with a small robot dog in the soft Martian soil. This is my happy place—a memory I created for myself using virtual reality (VR). But the truth is different. I am actually lying in a narrow sleep pod on the spaceship Hope. My real eyes are covered by VR goggles, and my body is strapped down to prevent floating. The spaceship is traveling through deep space at 25,000kilometers per hour. Outside, there is no sound, no wind, only the cold darkness of the universe. I use this VR world to stay sane. The journey to Proxima Centauri b will take 45 years. Many of my crewmates have given up on their mental health. But I have this hill. It reminds me of the meadows in New Zealand where I grew up. In my VR world, I can feel the grass, smell the flowers, and hear the birds. It is not real, but it feels real enough. Our mission is to find a new home for humans. Earth is dying, and we are the scouts. If we succeed, millions will follow. But sometimes I wonder: when we get there, will we bring our problems with us? Will we destroy that planet too? I hope not. I hope we learn from our mistakes. I hope the hill I imagine on Mars will one day be a real hill, where children can run free without VR goggles. Until then, I will keep visiting my imaginary hill, drawing strength from a world that exists only in my mind. 26. What color is the sky in the writer’s VR world on Mars? 27. Where is the writer actually located? 28. Why does the writer use the VR world? 29. How fast is the spaceship traveling? 30. What does the writer hope humans will learn from their past mistakes?
