任务三 ★★ 阅读理解 B（10 分）
The universe is everything around us. It includes space, all the matter and energy in space, and even time. The stars like the Sun, and planets like Earth are part of it. These planets go around the Sun, which is just one star among billions. The Moon is not a planet. It circles Earth and is also part of this huge system.
Scientists say the solar system is about 4.6 billion years old. They found this by studying rocks and small space stones. Earth seems permanent, but it’s not. The Sun, much bigger than Earth, will change too, possibly growing large enough to take in nearby planets like Earth one day.
The universe is about 13.8 billion years old. Scientists found this by looking at old stars and how fast the universe is getting bigger. This surprises scientists, because they expected gravity to slow the stars down.
Earth and humans are very young compared to the universe. Life on Earth has been around for 3.8 billion years, but humans have only been here for about 300,000 years. That’s a tiny bit of time—like a second in a whole year! We’ve explored only our own solar system, and even then, we haven’t seen all the planets and moons.
With new technology and curiosity, we keep learning about the universe. How did the universe begin? Are there other planets with life? Though space is big and full of secrets, each discovery helps us understand our place in it. The more we learn, the more we want to explore.

答案
任务三 答案速查 21.C 22.B 23.A 24.A 25.D
【主旨大意】本文主要介绍了宇宙的组成、太阳系的年龄、地球和人类的起源以及科学家对宇宙的探索。
21. C 【点拨】细节理解题。根据第一段中“The Moon is not a planet. It circles Earth and is also part of this huge system.”可知，月球是围绕地球运转的天体。
22. B 【点拨】词义猜测题。根据第二段中的“The Sun, much bigger than Earth... like Earth one day.”并结合前文中的“Earth seems permanent, but it's not.”可推知，permanent在此处的意思是“永恒的、无尽的”。
23. A 【点拨】推理判断题。根据“This surprises scientists, because they expected gravity to slow the stars down.”可推知，空缺处应填入与恒星的速度相关的内容。选项A符合语境。
24. A 【点拨】细节理解题。根据“Scientists say the solar system is about 4.6 billion years old.”“The universe is about 13.8 billion years old.”以及“Life on Earth has been around for 3.8 billion years, but humans have only been here for about 300,000 years.”提取宇宙、太阳系、地球上的生命、人类的形成时间先后关系：宇宙约138亿年（最早形成），太阳系约46亿年，地球上的生命约38亿年，人类约30万年。正确的时间线是：宇宙→太阳系→地球上的生命→人类。
25. D 【点拨】最佳标题题。根据文章内容可知，文章不仅介绍了宇宙的组成和年龄，还讨论了地球、人类以及科学家对宇宙的探索，强调了人类在宇宙中的位置。因此选项D“宇宙和我们在其中的位置”最适合作为文章的标题。
