In the summer f 2025,16-year-ld Li Hua fund the small river near his hmetwn,nce his childhd playplace,cvered with dead fish and smelling terrible.The river was plluted by unprcessed waste water frm a nearby small factry and randm garbage frm villagers,which filled Li Hua with sadness and a strng sense f respnsibility.
As a science-lving high schl student,Li Hua decided t save the river.His parents and classmates thught he was t yung t make a difference,but he didn’t give up.Remembering his science teacher’s wrds that"science is in daily life",he started cllecting water samples after schl every day.With his teacher’s help,he used the schl lab’s simple equipment t test water quality,recrding pH value and nutrient data carefully every day.
The prcess was tugh.He ften walked n muddy riverbanks,and unsatisfactry test results made him frustrated.But seeing villagers’ disappinted lks at the dirty river,he kept ging.After a mnth,he gt a cmplete set f data and fund the cre pllutin causes.He then wrte a detailed reprt with practical slutins:asking the factry t install a waste water treatment system and setting up garbage bins alng the river.
Li Hua sent the reprt t the lcal envirnmental bureau and village cmmittee.T his surprise,it was highly valued.The bureau rdered the factry t stp prductin fr rectificatin,and the village set up garbage bins and rganized a river cleaning activity.Three mnths later,the river turned clear again,with small fish swimming in it.Li Hua became a lcal"science star",and he said,"Science is pwerful—curisity and persistence can make a real difference."

Artificial intelligence(AI)has becme an indispensable tl in scientific research in 2025,and its develpment in 2026 is grwing faster and mre diversified.Frm aerspace t bichemistry,frm green energy t climate predictin,AI is pushing scientific prgress in almst all fields,changing the way researchers wrk and explre the unknwn.
In aerspace explratin,AI greatly imprves efficiency and accuracy.In the past,analysing space data frm satellites needed lts f human resurces and time,but nw AI algrithms can prcess massive data in a shrt time,find hidden useful infrmatin and predict space missin risks in advance.The China Manned Space Prgram has applied AI t the space statin’s cntrl system,making its peratin mre stable and safe,and AI als helps design mre reasnable aerspace equipment by simulating space envirnments.
In bichemistry research,AI shrtens the new drug develpment cycle greatly.Traditinal drug develpment takes 10-15 years and csts billins f dllars,but AI can simulate the interactin between drugs and human cells,screening ptential drug mlecules frm millins f cmpunds quickly.In 2025,an AI-assisted lung cancer drug was put n the market after nly 3 years f research,and in 2026,mre pharmaceutical cmpanies are cperating with AI firms t research drugs fr rare diseases.
In green energy and climate predictin,AI als plays a key rle.It cllects and analyses renewable energy generatin data in real time,predicting pwer utput by weather and terrain t adjust energy distributin,imprving the utilizatin rate f slar and wind energy.Fr climate predictin,AI analyses 100 years f histrical climate data t predict future 50-year trends mre accurately,prviding a scientific basis fr glbal climate change respnse.Hwever,AI is just a tl—scientific prgress still needs human wisdm and creativity.
28.What is the main idea f the passage?
A.The histry f AI develpment in scientific research
B.AI’s applicatin and develpment in scientific research 2025-2026
C.The differences between traditinal and AI-assisted research
D.The challenges AI faces in scientific research
29.Hw des AI help in aerspace explratin?
A.It can replace astrnauts t finish spacewalks
B.It can prcess large amunts f space data quickly and accurately
C.It can independently develp new energy fr aerspace equipment
D.It can build space statins in a shrt time
30.What is the advantage f AI in new drug develpment?
A.It shrtens the drug develpment cycle
B.It makes drugs mre expensive
C.It reduces the number f drug mlecules
D.It makes drug testing mre cmplicated
31.Which field is NOT mentined fr AI’s applicatin in scientific research?
A.Aerspace explratin B.Bichemical research

In 2025-2026,with the ppularizatin f science educatin in middle and high schls,mre teenagers are interested in scientific research,which has caused a heated scial debate.Sme peple supprt teenagers’ participatin in scientific research,while thers ppse it,believing teenagers are nt mature enugh fr such wrk.
Supprters hld that encuraging teenagers t d scientific research has great benefits.Firstly,it cultivates their scientific literacy and innvative thinking.Scientific research requires careful bservatin,lgical analysis and bld explratin—abilities that are crucial fr their grwth.By ding research,teenagers learn t think independently and slve prblems with scientific methds.Secndly,it aruses their interest in science,laying a fundatin fr future scientific talents.Glbal science and technlgy cmpetitin is fierce,and cuntries need a large number f yung scientific talents.Teenagers’ unique curisity can als bring new ideas t scientific research,breaking adults’ inherent thinking mdes.
Oppnents argue that teenagers are nt suitable fr scientific research.They are still learning basic knwledge and lack prfessinal research abilities and experience.Scientific research is rigrus and cmplex,and teenagers have limited time and energy after finishing daily curses.Besides,scientific research is full f failures,and teenagers’ psychlgical endurance is weak—t much pressure may make them frustrated and lse cnfidence in learning.Sme parents and schls als veremphasize research results,making teenagers pursue success blindly and ignre the explratin prcess.
In my pinin,teenagers shuld be encuraged t d scientific research,but in a prper way.Research activities shuld be cmbined with their textbk knwledge and cgnitive level,nt t prfessinal r cmplex.The fcus shuld be n cultivating interest and basic abilities like data analysis and experiment design.Schls and parents shuld prvide guidance and a relaxed envirnment,paying mre attentin t the prcess rather than results.Sciety shuld als ffer mre platfrms like science camps and schl lab pen days.In this way,teenagers can gain grwth frm scientific research and becme ptential scientific talents fr the cuntry.
32.What is the authr’s attitude twards teenagers ding scientific research?
A.Ttally against B.Supprtive with prper methds
C.Cmpletely neutral D.Dubtful abut its effects
33.What is ne benefit f teenagers ding scientific research accrding t supprters?
A.It helps them skip basic knwledge learning
B.It cultivates their scientific literacy and innvative thinking
C.It makes them becme famus scientists quickly
D.It reduces their daily study pressure
34.What is the main reasn ppnents think teenagers are unfit fr scientific research?
A.They have t much curisity abut science
B.They lack prfessinal knwledge and research ability
C.Their thinking is t unrestrained t fllw research rules
D.They have n interest in real scientific research
35.Hw can we help teenagers d scientific research prperly?
A.Let them d highly prfessinal and cmplex research
B.Overemphasize research results and ignre the prcess
C.Cmbine research with their textbk knwledge and cgnitive level
D.Refuse t prvide any guidance and let them research alne

My First Scientific Experiment
When I was in Grade 10,learning Unit 3 The wrld f Science made me eager t d a scientific experiment by myself.My science teacher Mr.Wang nticed my interest and encuraged me t try.I decided t prve that phtsynthesis is essential fr plant grwth,buying tw same-sized mung bean ptted plants,a black clth,a watering can and a ntebk fr data recrding.
Mr.Wang taught me the experiment steps:put ne plant in the sun and water it regularly,cver the ther with the black clth t blck sunlight,and water it with the same amunt f water every day.I recrded their initial state n the first day:bth had green leaves and small buds,lking lively.Then I started the experiment carefully,watering them at the same time every mrning and recrding changes every evening.
At first,everything went well.The plant in the sun grew better with mre leaves and lnger stems,while the cvered ne turned a little yellw n the third day with stpped bud grwth.I felt wrried and asked Mr.Wang fr help,wh tld me t keep ging and recrd every change carefully.
On the seventh day,a sudden rainstrm hit ur city.Busy preparing fr mid-term exams,I frgt t bring the ptted plants indrs.When I remembered,the rain had stpped.I rushed t the balcny and fund the sun-expsed plant standing firmly,but the cvered ne had fallen ver,with sil all ver the balcny...
Paragraph 1
I felt extremely sad and wanted t give up the experiment at that mment.


Paragraph 2
After tw mre weeks f careful care and bservatin,I finally cmpleted the experiment.
