四、(2025·泰州市泰兴市期末改编)(跨生物·奇妙的萤火虫)阅读理解。
① Imagine you are in a field at night，and suddenly，you see lots of little lights around you. You have just found a group of fireflies(萤火虫)，and their twinkling(闪烁的) lights are like a secret language. This nighttime light show，especially in the forest，has interested people for a long time. Let's explore the secret of fireflies.
② Do you know how fireflies make their tails shine? The special power of fireflies is called bioluminescence(生物发光)，a special ability to create their own light through a chemical reaction(化学反应). It happens when two chemicals in their bodies join together and produce light.
③ However，why do fireflies need to produce light in the dark? Imagine you are a firefly looking for someone special in the dark. How would you find Mr or Ms Right? Fireflies use their lights to send “hello” messages to each other. Each kind of firefly has its own special way to shine. They use their lights as an invitation to get to know each other better so that they can have baby fireflies.
④ But fireflies do not just use their lights for conversations. They also use them to stay safe. Imagine you are an adult firefly in the dark，and a big spider is trying to catch you. What do you do? You turn on your light to make a sign that tells the spider “I taste disgusting. You won't like me. So don't eat me.”.
⑤ Besides，some scientists say fireflies may also use their lights to hunt. Imagine you're a hungry firefly waiting in the dark. You flash lights to trick other insects into coming closer. When the curious prey(猎物) gets near—suddenly! You catch a quick snack. It's like using a glowing “free food” sign to attract dinner!
⑥ This story of fireflies tells us how amazing and wonderful the natural world is. Exploring the world of fireflies helps us see how important it is to take care of nature and all its amazing organisms(生物)，no matter how small they are.
1. How do fireflies make their tails shine?
A. By collecting sunlight in the day.
B. By collecting little lights around.
C. Through a chemical reaction inside.
D. With the help of other insects.
2. (创新考法·组合选择)Why do fireflies need to make light in the dark according to the passage?
a. To help stay safe.
b. To see their way clearly at night.
c. To make the night more beautiful.
d. To talk to each other as a language.
e. To hunt for other insects.
A. ade
B. acd
C. bce
D. abc
3. What does the underlined word “disgusting” mean in the passage?
A. Hot.
B. Sweet.
C. Awful.
D. Delicious.
4. Why does the writer use “Imagine you are...” in Paragraphs 1，3，4&5?
A. To give readers suggestions on how to get to know fireflies more.
B. To make the passage more scientific and make people believe it.
C. To express disagreement with people for not protecting fireflies well.
D. To make the passage more interesting and catch readers' attention.

四、（2025·泰州市泰兴市期末改编）（跨生物·奇妙的萤火虫）阅读理解。
①想象一下，你夜晚在一片田野里，突然，你看到周围有许多小光点。你刚刚发现了一群萤火虫，它们闪烁的光就像一种秘密语言。这场夜间灯光秀，尤其是在森林里的，长久以来都让人们很感兴趣。让我们探索一下萤火虫的秘密。
②你知道萤火虫是如何让它们的尾巴发光的吗？萤火虫的特殊能力被称为生物发光，这是一种通过化学反应产生自身光亮的特殊能力。当它们体内的两种化学物质结合在一起时就会产生光。
③然而，萤火虫为什么需要在黑暗中发光呢？想象一下，你是一只在黑暗中寻找意中人的萤火虫。你会如何找到你的另一半呢？萤火虫用它们的光互相传递“你好”的信息。每一种萤火虫都有自己独特的发光方式。它们用自己的光作为一种邀请，以便更好地了解彼此，这样它们就可以孕育萤火虫宝宝了。
④但是萤火虫发光不仅仅是为了交流。它们也用光来保证安全。想象一下，你是一只在黑暗中的成年萤火虫，一只大蜘蛛正试图抓住你。你会怎么做呢？你会点亮你的光，发出一个信号，告诉蜘蛛“我尝起来很恶心。你不会喜欢我的。所以别吃我。”
⑤此外，一些科学家说萤火虫也可能用它们的光来捕猎。想象一下，你是一只饥饿的萤火虫，在黑暗中等待着。你闪烁着光，诱骗其他昆虫靠近。当好奇的猎物靠近时——突然！你就快速地捕获了一顿小吃。这就像用一个发光的“免费食物”标志来吸引晚餐一样！
⑥萤火虫的这个故事告诉我们自然界是多么神奇美妙。探索萤火虫的世界有助于我们认识到，无论生物多么渺小，爱护自然和所有神奇的生物是多么重要。
1. 萤火虫是如何让它们的尾巴发光的？
A. 通过在白天收集阳光。
B. 通过收集周围的小光点。
C. 通过体内的化学反应。
D. 在其他昆虫的帮助下。
2. （创新考法·组合选择）根据文章，萤火虫为什么需要在黑暗中发光？
a. 为了保证安全。
b. 为了在晚上看清路。
c. 为了让夜晚更美丽。
d. 作为一种语言互相交流。
e. 为了捕猎其他昆虫。
A. ade
B. acd
C. bce
D. abc
3. 文章中划线单词“disgusting”是什么意思？
A. 热的。
B. 甜的。
C. 糟糕的、难吃的。
D. 美味的。
4. 作者在第1、3、4和5段中为什么使用“想象你是……”？
A. 给读者关于如何更多地了解萤火虫的建议。
B. 使文章更具科学性，让人们相信它。
C. 表达对人们没有很好地保护萤火虫的不满。
D. 使文章更有趣，吸引读者的注意力。
