Althugh scientists try t make sure nthing ges wrng, accidents can still happen.They als really wish t discver ther planets that are suitable enugh t supprt life.The future f space explratin remains bright.After many experiments, they succeeded in making rckets that culd escape Earth’s gravity.
Can yu chse the crrect sentence t fill in the gap?
“Are we alne? What’s ut there?” Lking up at the stars, peple have always wanted t learn mre abut space, and scientists wrk hard t find answers. They make vehicles t carry brave peple int space t find ut the secrets f the universe. They als really wish t discver ther planets that are suitable enugh t supprt life.
Why d peple want t explre space?
discver ther planets that are suitable enugh t supprt life

Humans have always had _______________ abut space.
a natural curisity
Space explratin carries human’s curisity.
Why des the passage begin with tw questins?
T impress readersT attract readers’ attentin and curisity abut the cntentT raise readers’ reflectin
Befre the mid-20th century, mst peple felt travelling int space was an impssible dream. Hwever, sme scientists were determined t help humans realise their dream t explre space. After many experiments, they succeeded in making rckets that culd escape Earth’s gravity. On 4 Octber 1957, the Sputnik 1 satellite was lunched by the USSR and successfully rbited arund Earth. Afterwards, the USSR fcused n sending peple int space, and n 12 April 1961, Yuri Gagarin became the first persn in the wrld t g int space. Over eight years later, n 20 July 1969, American astrnaut Neil Armstrng stepped nt the mn, famusly saying, “That’s ne small step fr [a] man, ne giant leap fr mankind.” Fllwing this, many mre gals were achieved. Fr example, America’s NASA space agency launched Vyager 1 n 5 September 1977 t study deep space, and it still transmits data tday.

That’s ne small step fr a man, a giant leap fr mankind.
Space explratin mtivates human’s determinatin, persistence, curisity, effrt and ambitin.

Why was space explratin mainly carried ut by the USSR and the US in the 20th century?

Hw des the writer shw the achievements in space explratin?using examples C. giving specific number making cmparisnD. giving definitin
Writing tip 1 : Examples and specific numbers can make a scientific article mre pervasive and bjective.
What are benefits f using examples and specific numbers?T be mre detailed, vivid and persuasive T impress readers with great prgress in space explratinT make it mre easy-understanding

Space travel became __________ in the 20th century with ________ and ________________ remarkable missin.
the Sviet Unin
Space explratin is always successful and satisfying?
D humans stp explring space due t prblems r failures?
Why dn’t humans stp?
Althugh scientists try t make sure nthing ges wrng, accidents can still happen. All the astrnauts n the USSR’s Syuz 11 and America’s Challenger died during their missins. These disasters made everyne sad and disappinted , but the desire t explre the universe never died. This is because peple believe in the imprtance f carrying n space explratin despite the huge risks. An example f this nging wrk is the Internatinal Space Statin. It rbits Earth and has astrnauts frm different cuntries n bard, prviding a cntinuus human presence in space.

Space travel has always invlved _________, but despite ______ explratin _________.

July 23, 2020, Tianwen 1 – a Mars prbe, was sent t the Space.
Zhurng, ne f the missin rver f the Tianwen 1, is tasked with detailed missin.
China als made great prgress in space explratin!
China’s space prgramme started later than thse f Russia and the US, but it has made great prgress in a shrt time. China became the third cuntry in the wrld t independently send humans int space in 2003, when Yang Liwei successfully rbited Earth in the Shenzhu 5 spacecraft. Then Shenzhu 6 and 7 cmpleted a secnd manned rbit and the first Chinese spacewalk, fllwed by the vehicle Jade Rabbit being sent t the mn t study its surface. After that, China launched the Tiangng 2 space lab int space and Tianzhu1 t dck with it. This signalled ne step further in China’s plan t establish a space statin in the future. Mre recently, China has sent Chang’e 4 t explre the surface f the far side f the mn t make measurements and bservatins.
