That was his toy car. There were four small wheels on it！ So pleased was Allen that he grasped it immediately. He carefully took off the wheels from the toy car which had accompanied him through his childhood. Now its wheels would aid him to give a helping hand to a poor cat. Allen got all the necessary materials for the wheelchair ready. Then he went to the neighbor’s to measure the cat and came back with the data. His father helped to cut the umbrella frame into several bars and assisted Allen in connecting the components. 　　Together， they built a tiny wheelchair for the little cat. The caring boy was excited and proud when he looked at the wheelchair. It was a joint effort. Holding the little wheelchair， Allen rushed to the neighbor’s. Witnessing the little cat placed in the small wheelchair， Allen was looking forward to the moment that it would move around by itself. As he had expected， the little cat rose to its feet with the support for the hind legs. It did move， though slowly！ Seeing this， Allen couldn’t help clapping and jumping with joy. His kindness and creation did make a difference to the little creature. 学科网（北京）股份有限公司 $ UNIT 5　Learning from nature Ⅰ.阅读理解 　　（2025·茂名二模）An atmospheric researcher Lubna Dada， who is part of an international project called CLOUD， and her team conducted a new study. The study looks at the role of trees and the natural compounds （混合物） they release into the atmosphere in cloud formation. The goal is to more precisely understand the climate before the Industrial Revolution — and how it’s changed since. 　　Clouds are not only important for the weather — they also help shape the climate. Some clouds act as a layer of protection between incoming solar radiation and Earth， cooling the atmosphere. Other clouds do the opposite：They act like a blanket and trap heat. 　　“But many current climate models don’t account for either the warming or cooling effects of clouds， or the role aerosols play in cloud formation. That is the biggest uncertainty in climate science at present.” Dada says. 　　Dada and the team are trying to figure it out using a steel， cylindrical room that roughly recreates the atmosphere. To do that， the team covers the room with tape. It has lights that seem like different layers of the atmosphere， and the researchers can change the humidity and temperature levels to create a given geographic location. Then， Dada and her team can add specific vapors into the room to study their effects. Dada says that previous research has looked at the effects of two kinds of organic emissions released by plants： monoterpenes and isoprene. But another kind of compound， sesquiterpene （倍半萜烯）， has largely been ignored. 　　In a recent study from the CLOUD project， scientists tested the effects of sesquiterpenes on cloud formation. They added all three compounds — monoterpenes， isoprene and sesquiterpenes — into the CLOUD room to see how many new particles （微粒） formed. They found that sesquiterpenes formed ten times more particles than the other two substances at the same concentrations. 　　Dada says this finding will help scientists understand the role natural emissions played in the preindustrial climate and how much humans have changed that. 1.Why did the researchers conduct the study？（　　） A.To recreate the preindustrial climate. B.To explore the warming effects of clouds. C.To understand cloud formation and climate changes better. D.To access the impact of trees on weather patterns more precisely. 2.What does the underlined word “That” in Paragraph 3 refer to？（　　） A.Climate model. B.Cloud formation. C.The cooling effect of clouds. D.The warming effect of clouds. 3.In which section of a magazine can readers find this text？（　　） A.Entertainment.　　　　　 B.Finance. 　　　 C.Culture.　　　　　 D.Environment. Ⅱ.阅读七选五 　　（2025·永州三模）As the seasons are starting to change around the world， the animal kingdom is on the move. Animal migration is one of nature’s great wonders， but how do animals know when it is time to set off on their journey， or where they need to go？ Once they’ve worked out their destination， how do they know how to get there？ 4.（　　）. 　　Migration is a behavioral pattern where animals travel from one habitat to another in search of something. It happens seasonally， and usually involves a return journey. These journeys can be by land， sea or air. 5.（　　）. Animals like gazelles， wildebeests and zebras migrate in huge herds during dry seasons to look for fresh grass to eat and water to drink. 　　Animals also migrate because of the weather. Around 50 bird species leave the UK each winter to avoid the cold. 6.（　　）. They’re either searching for a mate， looking for somewhere to lay their eggs or finding the best place to raise their young. For example， humpback whales travel to warmer waters each winter to raise their calves. 　　7.（　　），but how do they know when it is time to head off？ For those who migrate to look for something to eat， scientists think shortages of food could be a sign that it’s time to begin their journey. Others might be able to recognize when winter is coming because they can see that the days are getting shorter. 　　So how do they know where to go？ Some use the stars and the sun to help them navigate while others rely on landmarks like rivers and mountains to show them where they are.8.（　　）. Wildebeests are thought to follow the smell of rain. A.Below are some ways they get there B.Animals have their reasons for migrating C.Scientists have been puzzled by these questions for many years D.It’s also possible for animals to sniff their way to their destination E.Some birds travel to the UK to escape extreme cold further north F.One of the main reasons behind animal migration is the search for food G.For some animals， it’s the need to reproduce that sends them on their journey Ⅲ.读后续写 　　阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。 　　（2025·广东一模）Hearing that one neighbor had just welcomed a new litter， Allen， a 9-year-old boy， rushed to see the newborn cats. However， during his visit， Allen noticed one of the cats wasn’t moving due to disability on its hind （后面的） legs. So while the other little cats were exploring their surroundings， this one stayed behind. 　　Allen was significantly affected by the scene of this lonesome cat. He returned home and started to wonder whether he could do anything to help. When the boy told his mother about that， the mother recalled a video about pet wheelchairs. 　　They finally found the video on YouTube， in which an animal lover， Addy， shared a heartwarming and innovative project： building a wheelchair for a pet cat with mobility issues due to a hind-leg injury. As a caring pet owner， Addy took viewers through the DIY process of making a custom wheelchair to aid her cat’s movement and improve its quality of life. She began by measuring the cat and based on the measurements， cut the plastic pipes to make a frame （支架）. Then she connected the pipes and attached the wheels to the back end of the frame. Finally， she added a harness （保护带） to ensure it was fit and comfortable for the cat. 　　Seeing the cat in the wheelchair moving around happily with the support， Allen thought that would be the best option for the little cat. 　　But the wheelchair in the video seemed too big and too heavy for a newborn cat. Where could he find the suitable materials？ 　　His mother unearthed an old bag from the cupboard， whose belt was just fine for the harness. As for the frame， they searched the storage room in their house and found an old umbrella， whose frame provided enough thin iron bars that were durable and light. But they were difficult for him to cut off. Allen thought his father could help. However， where could they find the small wheels？ 注意：1.续写词数应为150个左右； 2.请按如下格式作答。 　　Allen suddenly spotted a familiar item in the corner of the storage room. 　　　　　　　　　　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　Together， they built a tiny wheelchair for the little cat. 　　　　　　　　　　　　　　　　　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 2 / 3 学科网（北京）股份有限公司 $
