In the summer of 2025,16-year-old Li Hua found the small river near his hometown,once his childhood playplace,covered with dead fish and smelling terrible.The river was polluted by unprocessed waste water from a nearby small factory and random garbage from villagers,which filled Li Hua with sadness and a strong sense of responsibility.
As a science-loving high school student,Li Hua decided to save the river.His parents and classmates thought he was too young to make a difference,but he didn’t give up.Remembering his science teacher’s words that"science is in daily life",he started collecting water samples after school every day.With his teacher’s help,he used the school lab’s simple equipment to test water quality,recording pH value and nutrient data carefully every day.
The process was tough.He often walked on muddy riverbanks,and unsatisfactory test results made him frustrated.But seeing villagers’ disappointed looks at the dirty river,he kept going.After a month,he got a complete set of data and found the core pollution causes.He then wrote a detailed report with practical solutions:asking the factory to install a waste water treatment system and setting up garbage bins along the river.
Li Hua sent the report to the local environmental bureau and village committee.To his surprise,it was highly valued.The bureau ordered the factory to stop production for rectification,and the village set up garbage bins and organized a river cleaning activity.Three months later,the river turned clear again,with small fish swimming in it.Li Hua became a local"science star",and he said,"Science is powerful—curiosity and persistence can make a real difference."
24.Why did Li Hua decide to save the river near his hometown

Artificial intelligence(AI)has become an indispensable tool in scientific research in 2025,and its development in 2026 is growing faster and more diversified.From aerospace to biochemistry,from green energy to climate prediction,AI is pushing scientific progress in almost all fields,changing the way researchers work and explore the unknown.
In aerospace exploration,AI greatly improves efficiency and accuracy.In the past,analysing space data from satellites needed lots of human resources and time,but now AI algorithms can process massive data in a short time,find hidden useful information and predict space mission risks in advance.The China Manned Space Program has applied AI to the space station’s control system,making its operation more stable and safe,and AI also helps design more reasonable aerospace equipment by simulating space environments.
In biochemistry research,AI shortens the new drug development cycle greatly.Traditional drug development takes 10-15 years and costs billions of dollars,but AI can simulate the interaction between drugs and human cells,screening potential drug molecules from millions of compounds quickly.In 2025,an AI-assisted lung cancer drug was put on the market after only 3 years of research,and in 2026,more pharmaceutical companies are cooperating with AI firms to research drugs for rare diseases.
In green energy and climate prediction,AI also plays a key role.It collects and analyses renewable energy generation data in real time,predicting power output by weather and terrain to adjust energy distribution,improving the utilization rate of solar and wind energy.For climate prediction,AI analyses 100 years of historical climate data to predict future 50-year trends more accurately,providing a scientific basis for global climate change response.However,AI is just a tool—scientific progress still needs human wisdom and creativity.
28.What is the main idea of the passage
A.The history of AI development in scientific research
B.AI’s application and development in scientific research 2025-2026
C.The differences between traditional and AI-assisted research
D.The challenges AI faces in scientific research

B.It can process large amounts of space data quickly and accurately
C.It can independently develop new energy for aerospace equipment
D.It can build space stations in a short time
30.What is the advantage of AI in new drug development
A.It shortens the drug development cycle
B.It makes drugs more expensive
C.It reduces the number of drug molecules
D.It makes drug testing more complicated
31.Which field is NOT mentioned for AI’s application in scientific research
A.Aerospace exploration B.Biochemical research
C.Primary school education D.Climate change prediction

My First Scientific Experiment
When I was in Grade 10,learning Unit 3 The world of Science made me eager to do a scientific experiment by myself.My science teacher Mr.Wang noticed my interest and encouraged me to try.I decided to prove that photosynthesis is essential for plant growth,buying two same-sized mung bean potted plants,a black cloth,a watering can and a notebook for data recording.
Mr.Wang taught me the experiment steps:put one plant in the sun and water it regularly,cover the other with the black cloth to block sunlight,and water it with the same amount of water every day.I recorded their initial state on the first day:both had green leaves and small buds,looking lively.Then I started the experiment carefully,watering them at the same time every morning and recording changes every evening.
At first,everything went well.The plant in the sun grew better with more leaves and longer stems,while the covered one turned a little yellow on the third day with stopped bud growth.I felt worried and asked Mr.Wang for help,who told me to keep going and record every change carefully.
On the seventh day,a sudden rainstorm hit our city.Busy preparing for mid-term exams,I forgot to bring the potted plants indoors.When I remembered,the rain had stopped.I rushed to the balcony and found the sun-exposed plant standing firmly,but the covered one had fallen over,with soil all over the balcony...
Paragraph 1
I felt extremely sad and wanted to give up the experiment at that moment.
Paragraph 2
After two more weeks of careful care and observation,I finally completed the experiment.Unit3 The world of Science单元检测卷-2025-2026学年-外研版高中英语必修第三册

参考范文：
Paragraph 1
I felt extremely sad and wanted to give up the experiment at that moment.Looking at the fallen plant and the messy soil,I regretted forgetting to bring it indoors.Just as I was about to clean up the balcony,Mr.Wang’s words echoed in my mind:"Scientific research often faces setbacks,and persistence is the key to success."I decided to try again.I carefully put the plant back into the pot,added some new soil,and continued to cover it with the black cloth.I also set a reminder on my phone to avoid missing any care tasks.
Paragraph 2
After two more weeks of careful care and observation,I finally completed the experiment.The plant in the sun had grown into a strong seedling with lush green leaves,while the one kept in darkness remained weak and yellow,with no new buds.I recorded the final data excitedly and drew a conclusion:photosynthesis is indeed essential for plant growth.When I showed the result to Mr.Wang,he praised me for my perseverance.This experience made me deeply understand that scientific exploration is full of challenges,but as long as we don’t give up,we will gain valuable discoveries.
