Take a close look at the world of insects, you’ll discover many unbelievable things. Consider butterflies, for example. They have beautiful, colorful wings. On summer days, you always see them flying freely. But, did you know how butterflies become flying insects? 1 In the beginning, female butterflies lay a small and colorful egg on a leaf or stem (茎) of a plant. It’s hard to believe that the egg will become something completely different in a few days. 2 This insect is called caterpillar (毛虫). It now has legs, eyes and a large body. A new life has begun. The caterpillar can eat, walk and see. But it is still not a butterfly. Soon, after growing big, the caterpillar makes a cover for itself. It covers itself in the nice protective blanket (保护层) and goes to sleep. 3 After a period of time, the blanket breaks and a wet, weak butterfly appears. It now has six legs, a mouth, eyes and wings. Shortly, the wings fill with blood, and the beautiful, colorful butterfly spreads its wings and flies away. 4 . And the cycle begins all over again. This is just one example of the wonders of nature. Look around the natural world, and you will learn many truly amazing things. A．After a few weeks, this adult butterfly lays her eggs. B．They have strong, fantastic flying skills. C．It’s one of the amazing wonders of nature. D．It becomes a walking insect. E．This stage is known as the “pupa (蛹)” stage. 【答案】1．C 2．D 3．E 4．A 【导语】本文是一篇说明文，按照完全变态发育的顺序，详细介绍了蝴蝶从卵→毛虫→蛹→成虫的完整生命周期，展现了大自然的神奇。 1．上文以问句 “But, did you know how butterflies become flying insects?”（但你知道蝴蝶是如何变成会飞的昆虫的吗？）引出蝴蝶的生长过程，下文开始介绍蝴蝶的生命周期起点（产卵）。C 项 “It’s one of the amazing wonders of nature.”（这是大自然令人惊叹的奇迹之一）承接上文的疑问，引出下文对蝴蝶生长过程的介绍。 2．上文提到 “the egg will become something completely different in a few days”（卵会在几天后变成完全不同的东西），下文紧接着介绍 “This insect is called caterpillar (毛虫). It now has legs, eyes and a large body.”（这种昆虫叫毛虫，有腿、眼睛和庞大的身体）。D 项 “It becomes a walking insect.”（它变成了会爬行的昆虫）完美衔接上下文，既对应了 “卵变成不同的东西”，又引出了下文的 “毛虫”。 3．上文描述了毛虫长大后 “covers itself in the nice protective blanket (保护层) and goes to sleep”（用保护层把自己包裹起来进入休眠），这正是蝴蝶生命周期中的蛹期。E 项 “This stage is known as the ‘pupa (蛹)’ stage.”（这个阶段被称为 “蛹期”）是对上文阶段的定义，承接自然，符合科普文的说明逻辑。 4．上文描述了蝴蝶破蛹而出、展翅飞走的成虫阶段，下文提到 “And the cycle begins all over again.”（生命周期重新开始）。A 项 “After a few weeks, this adult butterfly lays her eggs.”（几周后，这只成年蝴蝶会产卵）既承接了成虫阶段，又通过 “产卵” 呼应了生命周期的起点，完美衔接下文的 “循环重启”，完成了蝴蝶的完整生命周期闭环。 七、阅读理解。 Passage 1 Around the world, many wild animals are in danger of extinction (灭绝) because they have no place to live in.

You can give some money to nature reserves or spend your time helping the nature reserves to protect endangered animals. Step 3: Never buy anything that is made from endangered animals. Don’t do harm to (伤害) endangered animals or their living places. Instead, we should try our best to protect them. Step 4: Join an endangered animal protection organization (保护组织). You can save animals through these organizations by planting more trees and calling for more people to protect animals. If everyone works hard to protect endangered animals, we’ll get a more beautiful world. Let’s take action from now on! 1．Why are many wild animals in danger of extinction?

It lies in the Himalayas, between China and Nepal. Its height is about 8,848.86 metres—a measurement made by a Chinese team in 2020—and no other mountain on earth is as high as it. Climbing Qomolangma is extremely difficult, even for experienced climbers. The temperature there can drop to -30℃, and the air is very thin, which makes breathing hard. Some climbers even risk their lives to reach the top. The first Chinese team successfully reached the top in 1960, taking the northern route known as the “Death Route” for its dangerous conditions. In 1975, another Chinese team built a metal ladder on the Second Step—a steep, narrow part of the mountain—making it easier for later climbers to pass. Today, Qomolangma is more than just a mountain: it’s a symbol of courage and perseverance. We must protect this “highest natural wonder” from pollution and other human harms. 1．What makes Mount Qomolangma special according to the passage? A．It's the longest mountain in the world. B．It's the highest mountain in the world. C．It's the deepest mountain in the world. D．It's the widest mountain in the world. 2．What is the height of Mount Qomolangma? A．About 8,848.86 metres. B．About 11,000 metres. C．About 416 metres. D．About 5,464 metres. 3．Why is climbing Mount Qomolangma difficult? A．Because the weather is warm and the air is thick. B．Because there are too many tourists on the routes. C．Because the mountain is too short and easy to climb. D．Because the temperature is low and the air is thin. 4．When did the first Chinese team reach the top of Mount Qomolangma? A．In 2020. B．In 1975. C．In 1960. D．In 1990. 5．What should we do to protect Mount Qomolangma? A．Pollute it with climbing waste. B．Ignore its environmental problems. C．Keep it away from pollution. D．Build more hotels on its foot. 【答案】1．B 2．A 3．D 4．C 5．C 【导语】本文介绍了世界最高峰珠穆朗玛峰的地理位置、高度、攀登难度、首次登顶时间以及它的象征意义，呼吁保护这一自然奇观。 1．文章开篇第一句明确提到“Mount Qomolangma is the highest mountain in the world.”，这是珠穆朗玛峰最特别的地方。 2．第一段明确指出“Its height is about 8,848.86 metres—a measurement made by a Chinese team in 2020…”，因此珠穆朗玛峰的高度约为8848.86米。 3．第二段提到“The temperature there can drop to -30℃, and the air is very thin, which makes breathing hard.”，说明攀登困难的原因是气温低、空气稀薄。 4．第三段提到“The first Chinese team successfully reached the top in 1960…”，说明中国第一支队伍登顶的时间是1960年。 5．文章最后一句提到“We must protect this 'highest natural wonder' from pollution and other human harms.”，即我们应该让它远离污染来保护它。A、B、D选项均为破坏行为，不符合保护要求。 八、完形填空。 “The Arctic (北极) is dying,” researchers returning from the Arctic have predicted.

When the sea ice melts (融化), they won’t be able to 5 the hunger and are forced onto land. Scientists say the number of polar bears will drop by two-thirds to less than 10,000 by 2050. As the days get warmer, there’s 6 rain than snow in the Arctic. This hurts different kinds of animals. Many of them die because they can’t reach the food under the ice. 7 the World Wildlife Fund, the number of reindeer has dropped by 56 percent over the last 20 years.

Take a close look at the world of insects, you’ll discover many unbelievable things. Consider butterflies, for example. They have beautiful, colorful wings. On summer days, you always see them flying freely. But, did you know how butterflies become flying insects? 1 In the beginning, female butterflies lay a small and colorful egg on a leaf or stem (茎) of a plant. It’s hard to believe that the egg will become something completely different in a few days. 2 This insect is called caterpillar (毛虫). It now has legs, eyes and a large body. A new life has begun. The caterpillar can eat, walk and see. But it is still not a butterfly. Soon, after growing big, the caterpillar makes a cover for itself. It covers itself in the nice protective blanket (保护层) and goes to sleep. 3 After a period of time, the blanket breaks and a wet, weak butterfly appears. It now has six legs, a mouth, eyes and wings. Shortly, the wings fill with blood, and the beautiful, colorful butterfly spreads its wings and flies away. 4 . And the cycle begins all over again. This is just one example of the wonders of nature. Look around the natural world, and you will learn many truly amazing things. A．After a few weeks, this adult butterfly lays her eggs. B．They have strong, fantastic flying skills. C．It’s one of the amazing wonders of nature. D．It becomes a walking insect. E．This stage is known as the “pupa (蛹)” stage. 七、阅读理解。 Passage 1 Around the world, many wild animals are in danger of extinction (灭绝) because they have no place to live in.
