B You already know why cicadas ( 蝉 ) are so unbelievably noisy:males produce the sound to attract females.But do you know some of them appear above ground only every 17 years? There are more than 3,000 kinds of cicadas,which fall into two types:annual cicadas,which emerge (出现)every year,and periodical(周期)cicadas,which spend most of their lives underground and only emerge once every few years.The 17-year cicada is one of the periodical cicadas with the longest known insect life cycle.Every 17 years,like clockwork,they appear.Shortly after hatching(孵化)from its egg,a 17- year-old cicada nymph(若虫)digs down into the ground,where it spends—as its name suggests—the first 17 years of its life.When it comes out from the ground,it lives only four to six more weeks—just long enough to lay eggs,and the cycle starts all over again. Periodical cicadas don’t spend their years sleeping underground.Instead,they are active in their wingless nymph forms,digging tunnels(隧道). Though not proven,many scientists believe that the periodical cicada has a molecular clock(分子钟) inside its body that notes the passing of years through environmental signs.As trees go through their seasonal cycles,the sap(汁)of their roots (根)changes.And when cicada nymphs feed on this sap,they are likely to pick up signs of the passing of time.The 17th trees' seasonal cycle gives the nymphs their final sign:it's time to emerge. When the cicada nymphs come out from their underground homes depends on temperature.After their 17 years are up,the cicadas wait for the perfect temperature before making the journey to the surface—when the soil about 8 inches(about 20 cm) underground reaches 64F,or about 18℃.This means that cicadas will appear at different times in different parts of the world:the soil in one place may reach the ideal temperature before the soil in another.But once that temperature is reached,all the cicadas in the area will feel it and make the journey to the surface together. When they emerge,the cicadas aren't yet in their adult form.They're still nymphs,and they remain so until they molt(蜕皮)for the final time.Once their fresh exoskeletons(外骨骼)have hardened,they take to the trees with their new-found wings,and the males begin their loud mating calls in order to attract females.Then females lay eggs in dry branches.After that,both males and females die. And now we're back where we started.Newborn cicada nymphs fall or move down from the trees and go into the ground,not to be seen for another 17 years. ( )1.Which one is TRUE about periodical cicadas? A. All of them make loud noises. B.They emerge every year. C.They hatch underground. D.They have different life-cycle lengths. ( )2.What may the 17-year cicadas do underground during the first 17 years of their lives? A. Laying eggs. B.Sleeping all the time. C.Hatching from eggs. D.Digging tunnels. ( )3.How do cicadas know when 17 years have passed according to scientists? A. By feeling the environmental changes. B.By climbing up trees. C.By testing the temperature. D.By getting information from adult cicadas. ( )4.What decides a cicada's emergence time? A. The temperature. B.The soil. C.The area where it stays. D.Its exoskeleton. 二、书面表达 （一） [2025山东德州调研]智慧科技赋能学习创 新。随着科技的发展，人工智能(AI) 将越来越多 地被应用于课堂。你觉得未来的课堂会变成什么样子呢?你将如何利用AI 来辅助学习?新的 学习方式会给你带来什么好处? 提示词语 ：robot,make a difference,improve, creative ideas 提示问题： ·What will the future classroom be like? ·How will you learn with the help of AI? ·What benefits can you get from the new ways of study? 要求： 1.行文连贯，用到所给提示； 2.不少于80词。 ______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ （二） [2025安徽合肥期中]你们学校社团即将举办以“My Life in 2035”为题的英文演讲比赛。请你围绕下表所示的三个问题，写一篇英文演讲稿谈谈十年后你的生活。 My Life in 2035 Where will I live?(a big city;a quiet village.…) What job will I have?(I hope to..;I can.…) How will new technology help me?(cars;robots..) 注意：1.根据上表所给提示，适当发挥； 2.文中不得出现真实的姓名和校名； 3.词数80左右，开头和结尾已给出，不计入总词数。 My Life in 2035 Hello everyone, Let me share something about what my life in 2035 may be like with you.______ __________________________________________________________________________________________________________________________________________ _____________________________________________________________________ _____________________________________________________________________ _____________________________________________________________________ _____________________________________________________________________ 答案： 一、 快速对答案 1-5 C C B A C 1.
