Lk at the pictures and answer the questins. Use the wrds and expressins t help yu.
new discveries
e.g. I think the three inventrs were great scientists. They were curius and brave t d dangerus research. They made new discveries. They were pineers t discver the unknwn and made the wrld develp...
Read the passage and check yur answers.
1 Albert Einstein nce said, “I have n special talents. I am nlypassinately curius.” The greatest inventins in histry wuld beimpssible withut curisity.2 Curisity can bring new discveries. Benjamin Franklin is a greatexample. He was drawn t electricity and had a deep curisity abut its nature. He did lts f research t try t understand it. Fr example, he flew a kite during a strm. His curisity led him t invent the lightning rd. This inventin prtects buildings frm lightning.
The pwer f curisity
3 Curisity can als make peple brave. Just lk at Wan Hu, theMing Dynasty pineer f space explratin. He was s curius abut space that he invented a “flying chair”! He lst his life while testing this inventin. Despite the failure, his curisity gave future explrers ideas.Peple learnt frm his example, and created safer ways t explre space.4 But curisity is mre than just taking risks. It als drives pepletwards certain gals.Zhang Heng, a Chinese scientist and inventr, was curius abut the wrld: hw did everything in the wrld mve? He spent years studying the sky and the earth. Finally, he drew China's first star map, and invented the first earthquake detectr. His curisity cntinues t influence scientists tday.
5 As Jacques Custeau said, “ What is a scientist after all? It is acurius man lking thrugh a keyhle, the keyhle f nature,trying t knw what's ging n.” Curisity is the key. It pens nedr after anther fr us t discver a new wrld.
Jacques Custeau was a famus French explrer, scientist, and filmmaker. He was brn in 1910 and lved the cean. He wanted t explre what was under the water. In the 1940s, he helped invent the Aqua-Lung (a device fr breathing underwater). This made it easier fr peple t dive deep and study the sea. He als made many dcumentaries, like The Silent Wrld, t shw thers the beauty and secrets f the cean.

1 What wrds f famus peple des the writer use in the passage? What are their effects?
Answer the questins.
"What is a scientist after all? It is a curius man lking thrugh a keyhle, the keyhle f nature, trying t knw what's ging n."
"I have n special talents. I am nly passinately curius."
The qutes at the start and end f the article cnnect well, making the stry cmplete.
They make the article mre believable because famus peple said them.
They help explain the main idea: curisity is imprtant fr discvery and inventin.
2 What dr can the key f curisity pen?3 What ther examples can yu use t describe curisity?
Curisity can pen the dr t new discveries and new knwledge. It can als pen the dr f bravery and adventure.

ech with the first paragraph
The passage uses three main examples (Franklin, Wan Hu, Zhang Heng). Why d yu think the authr chse this rder? Hw des each example build n the previus ne?
Each example gets "deeper":First just abut discvering smething new.Then abut being brave t try.Finally abut wrking hard fr years.
This rder helps us see curisity isn't just abut quick ideas — it needs curage and patience t.
Think and Share
1 D yu think inventrs culd wrk withut curisity? Why r why nt?
N, I dn't think inventrs culd wrk withut curisity. Because the passage mentins that the greatest inventins in histry wuld be impssible withut curisity. Curisity can bring new discveries, make peple brave t try new things, and drive them twards certain gals. S curisity is the key mtivatin fr inventrs t explre and create.
