For example, flowers make sweeter nectar (花蜜) when they hear bees buzzing. Now, scientists in Israel think plants might also “talk”. Professor Lilach Hadany and her team at Tel Aviv University used microphones to record tomato plants in different situations. They found the plants made ultrasonic (超声波的) sounds. Then the researchers slowed down the recordings so that humans could hear them, and they heard sharp clicks. The researchers also found that plants hardly clicked when they had much water. But when the soil was dry, they clicked more. If a stem was cut off, they clicked more, too, but differently from when they needed water. It is known that plants make noise, especially when they are scared. Researchers trained an AI system to recognise the different clicks. It could tell if a plant needed water or had cuts about 70% of the time. This suggests we might use plant sounds to know if they have problems. It could help farmers. Do plants make sounds to talk to each other? Some research shows that plants send chemicals into the air when insects (昆虫) attack them, telling nearby plants to make chemicals that taste bad to drive away insects. The clicks might work the same way. 1. How did the researchers make humans hear the plant sounds? A. They used new recordings. B. They changed another microphone. C. They made the recordings slow. D. They watered the plants. 2. What does the underlined word “attack” mean in the last paragraph? A. collect B. hurt C. clean D. help 3. What do scientists think plants might be able to do when they meet trouble? A. Plants might be able to grow faster. B. Plants might be able to change colors. C. Plants might be able to communicate with others. D. Plants might be able to produce more fruit. 4. Where is the passage probably taken from? A. A geography textbook. B. A storybook. C. A tour guidebook. D. A science magazine. 5. Which one is true according to the passage? A. plants would click when they had much water. B. we might use plant sounds to know if they have problems. C. flowers never make sweeter nectar when they hear bees buzzing. D. plants make noise, especially when they are calm. 【答案】1. C     2. B     3. C     4. D     5. B      【解析】本文是一篇科普说明文，主要介绍了科学家的研究发现：植物不仅能感知声音，还会通过超声波“交流”——以色列团队记录到番茄植株在缺水、茎被切断等状况下会发出不同的超声波，AI可识别这些声音判断植物问题，研究或能帮助农业生产。 (1)题： 细节理解题。根据“They found the plants made ultrasonic sounds. Then the researchers slowed down the recordings so that humans could hear them, and they heard sharp clicks.”可知，研究者是通过放慢录音的速度，让人们听到了植物的声音，故选C。 (2)题： 词句猜测题。根据“Some research shows that plants send chemicals into the air when insects attack them, telling nearby plants to make chemicals that taste bad to drive away insects.”可知，此时植物会释放味道糟糕的化学物质来驱赶昆虫，所以猜测此处昆虫的行为是不利于植物的，结合备选项可知attack“伤害、侵袭”符合语境，故选B。 (3)题： 推理判断题。根据“Do plants make sounds to talk to each other? Some research shows that plants send chemicals into the air when insects attack them, telling nearby plants to make chemicals that taste bad to drive away insects.”可知，植物遇昆虫袭击时会释放化学物质传递信息，由此推断植物遇到麻烦时会相互交流，故选C。 (4)题： 推理判断题。根据全文可知，文章介绍了以色列科学家关于植物能发出超声波、可能互相交流的研究，所以判断文章可能出自科学杂志，故选D。 (5)题： 细节理解题。根据“this suggests we might use plant sounds to know if they have problems.”可知，我们可以利用植物的声音来判断它们是否出现问题，故选B。 一、阅读单选 （来源:2026年天津市中考英语试题）Strawberries taste sweet and delicious.

For example, flowers make sweeter nectar (花蜜) when they hear bees buzzing. Now, scientists in Israel think plants might also “talk”. Professor Lilach Hadany and her team at Tel Aviv University used microphones to record tomato plants in different situations. They found the plants made ultrasonic (超声波的) sounds. Then the researchers slowed down the recordings so that humans could hear them, and they heard sharp clicks. The researchers also found that plants hardly clicked when they had much water. But when the soil was dry, they clicked more. If a stem was cut off, they clicked more, too, but differently from when they needed water. It is known that plants make noise, especially when they are scared. Researchers trained an AI system to recognise the different clicks. It could tell if a plant needed water or had cuts about 70% of the time. This suggests we might use plant sounds to know if they have problems. It could help farmers. Do plants make sounds to talk to each other? Some research shows that plants send chemicals into the air when insects (昆虫) attack them, telling nearby plants to make chemicals that taste bad to drive away insects. The clicks might work the same way. 1. How did the researchers make humans hear the plant sounds? A. They used new recordings. B. They changed another microphone. C. They made the recordings slow. D. They watered the plants. 2. What does the underlined word “attack” mean in the last paragraph? A. collect B. hurt C. clean D. help 3. What do scientists think plants might be able to do when they meet trouble? A. Plants might be able to grow faster. B. Plants might be able to change colors. C. Plants might be able to communicate with others. D. Plants might be able to produce more fruit. 4. Where is the passage probably taken from? A. A geography textbook. B. A storybook. C. A tour guidebook. D. A science magazine. 5. Which one is true according to the passage? A. plants would click when they had much water. B. we might use plant sounds to know if they have problems. C. flowers never make sweeter nectar when they hear bees buzzing. D. plants make noise, especially when they are calm. 一、阅读单选 （来源:2026年天津市中考英语试题）Strawberries taste sweet and delicious.
