The brush pen, ne f the “Fur Treasures f the Study”， was invented thusands f years ag. Hwever, the ldest pen was just a stick. It was difficult fr peple t write well n thin silk.
It's said that Meng Tian, a general f the Kingdm f Qin, imprved the pen. When Meng was leading an army t fight against the Kingdm f Chu, he had t write reprts t his king. But his pen was t hard and caused him much truble, s he was thinking f ways t imprve it.

After arriving hme, he tied the rabbit's hair t a stick and tried writing with it. But the rabbit's hair was t smth(光滑的) t write well. Meng was s disappinted that he threw away his “inventin” int a stne hle in the yard.
Hwever, Meng never gave up and kept trying. A few rainy days later, he fund his “inventin” fatter in a stne hle. He picked it up with hpe. The brush wrked beautifully n silk. It turned ut that the special water cleaned the il frm the hair. Meng succeeded at last.

C(跨学科·生物)
Plants cannt mve like animals, but they cmmunicate and respnd(回应) t the envirnment thrugh their wn mvement—a type f “plant bdy language”. Scientists have been amazed by these mvements and created inventins based n them.
Everyne knws sunflwers turn t face the sun as it mves acrss the sky. This gave engineers the idea t create SmartFlwer slar panels(太阳能电池板). They are in the shape f flwers, and each “petal” (花瓣) is a slar panel. SmartFlwer fllws the sun all day. It helps prduce 40% mre energy than nrmal slar panels. After dark r when there's bad weather like heavy rain, the “petals” will clse up.
Sme plants, such as ivy (常春藤), can climb walls using sticky pads. The pads help ivy stick t wd, stne and ther surfaces. After studying this plant, scientists created sft climbing rbts. Thugh small, these rbts are strng enugh t mve n different surfaces and turn crners. This allws them t wrk in hard­t­reach places.
Anther amazing plant is the explding cucumber (喷瓜). It has a cl trick. When it is tuched, it shts seeds up t 6 meters away! Learning frm this plant's “bdy language”， medical researchers have develped a new way t send medicine t where it's needed in the bdy, just as the plants sht seeds t the right places.
Plants may seem quiet and still, but their special mvements have inspired real­wrld inventins. Next time yu see a plant, watch its “bdy language” carefully; yu might catch the next scientific breakthrugh!
9．( )Which picture best describes the inventin in Paragraph 2?
A. B. C. D.
10．( )Where is the climbing rbt designed t wrk?
A．Under deep water. B．In wide farm fields.
C．In narrw water pipes. D．On pen playgrunds.
11．( ) What is special abut the explding cucumber?
A．It can play tricks n thers. B．It can send ut the seeds far.
C．It helps peple make medicine. D．It can grw up t 6 meters tall.
12．( )(高阶思维·标题归纳) Which wuld be the best title fr the passage?
A．Nature's Mvement B．Plants Have Gne Wild
C．Nature's Language D．Plants Drive Creatins

①In tday's wrld, scientists are develping creative slutins t envirnmental prblems. Let's explre three grundbreaking nes.
② Engineers in Amsterdam have invented a new birdhuse. It has cmputers inside and is pwered by slar panels(太阳能电池板) n its rf. When the air is clean enugh, the birdhuse turns green and prvides free WiFi t peple nearby. If the air gets plluted(污染的), it turns red. Peple lve this idea. They ride bikes mre, s the air gets cleaner and they get free Internet.
③In Chile's dry desert areas, getting clean water is nt easy. Scientists created a smart machine. It takes water frm the air and wrks like this: when warm air tuches its cld surface, there will be water drps — just like n a__cld__drink__can. The machine cllects the water and cleans it. One such machine can prduce enugh water each day fr a family f fur t drink. Best f all, it uses slar pwer, s it wrks even in places withut electricity(电)．
④A famus British band had cl ideas fr their cncerts. They installed (安装) special flrs n stage called “Kinetic flrs”. The flrs can make electricity when fans dance. The band als ffered fans exercise bikes t ride, and this helped pwer the shw! At ne cncert, the electricity fans made was enugh t pwer 300 hmes fr an hur! Nw, many ther bands are fllwing these cl ideas.

Learning abut AI
__▲__
AI wrks by using algrithms (算法), r step­by­step instructins, t help cmputers understand and wrk with infrmatin. Fr example, if yu want t teach a cmputer t knw different types f fruits, yu can give it a lt f pictures f fruits and tell it which nes are apples, bananas, and s n. The cmputer will then use the infrmatin t find ut what new fruits are. This prcess is called “machine learning”.
What can AI be used fr？
AI is already being used in many different areas. Fr example, AI can be used t：
● diagnse and treat diseases；
● drive self­driving cars；
● recmmend mvies and TV shws accrding t yur viewing histry；
● help teachers give marks t papers.
The Future f AI
In the future, AI may cmpletely change many parts f ur lives and help us slve sme f the wrld's biggest prblems. Hwever, it's als imprtant t remember that AI is just a tl, and it's up t us t decide hw we use it. With respnsible and ethical (合乎道德的) use, AI can make the wrld a better place fr everyne！
