Now smartphones connect people instantly.Video calls let us chat face-to-face with relatives abroad whenever we want.

Before the railway was built,the trip between Mombasa and Nairobi was long and tiring People had to take old buses or trucks,which were slow and unsafe.Goods could not be trans- ported quickly,so many fruits and vegetables went bad on the way. Since the railway opened,everything has changed.The travel time is shortened to 4.5 hours,making it easy for people to visit their families and do business.Local farmers can transport their products to markets quickly,earning more money.Chinese workers also taught local people new skills,helping them find better jobs.

Humanoid robots-robots that look and act like humans-are no longer just a thing of science fiction.In recent years,China has made great progress in developing these robots,and they are starting to play an important role in people's lives. In factories,humanoid robots are being used to do repetitive and dangerous jobs.This helps workers avoid injuries and allows companies to produce goods more efficiently.In hos- pitals,some humanoid robots can help take care of patients by reminding them to take medicine or even guiding them through exercise. At home,these robots are becoming more common.Some can clean rooms,while others can talk with family members or help children with learning.Although they are still quite ex- pensive,the price is expected to drop as technology improves. However,not everyone is excited about humanoid robots.Some people worry that they may take away jobs from humans.Others are concerned about safety and privacy.As the tech- nology develops,society will need to find a balance between using robots and protecting hu- man interests.

In the past,people living in deep mountains had to walk for hours or even days to reach nearby towns.Roads were rough and dangerous,especially in bad weather.Children had to travel long distances to school,and sick villagers could not get to hospitals in time. Today,hundreds of modern bridges have been built across deep valleys and steep cliffs. These bridges are not only strong but also designed to fit the natural environment.Some are among the highest in the world,attracting tourists from all over the country. The benefits of these bridges go beyond transportation.They help local farmers sell their products to cities,bringing more income.They also make it possible for more children to at- tend school regularly.As one villager said,"This bridge is like a lifeline for us.It connects us not just to the town,but to hope."

To solve these problems,the Chinese government started a series of large-scale actions. One of the most important projects is the Three-North Shelterbelt Forest Program,also known as the "Great Green Wall".Millions of trees have been planted across northern China to stop sandstorms.These forests act as a shield,reducing the amount of dust that reaches cities. To fight air pollution,the government introduced stricter rules on factories and vehicles. Old coal-fired factories were closed or improved with cleaner technology.Cities began using more natural gas and renewable energy for heating.Electric buses and cars have become com- mon on the streets,helping to reduce vehicle emissions. Thanks to these efforts,the air quality has improved greatly.In 2024,the average density (of PM2s-a key measure of air pollution-in major cities dropped by more than 60% compared to ten years ago.Sandstorms have also become less frequent.While challenges re- main,China's experience shows that with strong action,environmental problems can be solved. 41.What problems did northern China face in the past? 42.What is the "Great Green Wall"and what does it do? 43.What measures did the government take to reduce air pollution? 44.What do you think is the most important lesson from China's experience in fighting environmental problems?Why?(write 30 words or more) 五、书面表达 45.本单元主题为The Changing World,请你以Great Changes in My Hometown为题， 写一篇英语短文，介绍家乡的变化，体现乡村振兴成果。 要点： 1.描述家乡过去的样子（道路、房屋、人们的生活）： 2.描述家乡现在的变化（道路、房屋、人们的生活、产业发展）： 3.谈谈你对家乡变化的感受和对未来的期待。 要求： 1.词数80一100，开头已给出，不计入总词数； 31 页语心九年级上册人教版》 2.语句通顺，逻辑清晰，不出现真实人名、校名： 3.紧扣主题，内容完整。 Great Changes in My Hometown My hometown is a small village in China.It has changed a lot in the past ten years, thanks to the rural revitalization policy. 2页语心九年级上册人教版 Unit 8 More Than a Game 第一课时 一、1-4BABB 二、I-5 BACCA6-I0 ABCAB 1.challenges 2.broke 3.it 4.to give 5.the 6.was hit 7.with 8.successfully 9.longer 10.but 第二课时 一、1-4BCBD 二、I-5 ABABC6-10 ABBAB 三、1-4BCDA 1.an 2.were 3.first 4.to keep 5.their 6.safely 7.races 8.more 9.and 10.with 第三课时 -、1-4EABD 二、I-5 BBAAC6-10 DBCBA 三、l.200 students. 2.Basketball. 3.Because they are easier to play indoors and do not need a large playing field. 4.I think team sports are better because they teach us how to work with others and build friendship.Playing together also makes sports more fun and helps us learn to support each other. 四、1-4BABA 第四课时 -、1-4BCCB 二、I-5 ADBCB6-10 CDDAC 1.will love 2.himself 3.and 4.building 5.better 6.happiness 7.wonderful 8.With 9.be given 10.a 1.Because she was afraid of making mistakes in front of others. 2.They cheered for her and stayed after practice to help her improve. 3.She found a group of friends who believed in her and leamed to believe in herself. 4.The most important benefit of team sports is leaming to trust and support others.They teach us that we can achieve more together than alone,and they help us build lasting friendships and confidence. 五、I-5 BDAAC6-10 DBDCC11-15 ABCAD Unit1单元作业 1-4 BBCA 5-8 BACB 9-12 BBCB 13-16 BBCC 17-20 DBEC 二、21-25 ACBAC26-30 BBCDA 31.rapidly 32.depended 33.to talk 34.on 35.carring 36.than 37.have lived 38.for 39.wisely 40.will create 41.Sandstorms in spring and thick smog in winter. 42.It is a forest program that plants millions of trees to stop sandstorms. 43.They closed old factories,used cleaner energy,and encouraged electric vehicles. 200 参考答案《● 44.The most important lesson is that strong government action can solve environmental problems.With good plans and hard work,we can make the air cleaner and reduce pollution. 五、 Great Changes in My Hometown My hometown is a small village in China.It has changed a lot in the past ten years,thanks to the rural revitalization policy.
