Space Explratin (2)Reading and Thinking
Learn abut the develpment f space explratin
Befre yu read, lk at the title and the phts. Discuss these questins in pairs.
1. What d yu think are the main reasns fr space explratin?2. What d yu expect t read abut in this text?
The main reasns fr space explratin are t further human explratin and t gather knwledge f the universe.
I expect t read abut the future f space travel.
Read the text. Several sentences have been remved frm it. Chse the crrect sentence (A-D) t fill each gap.
A. Althugh scientists try t make sure nthing ges wrng, accidents can still happen.B. They als really wish t discver ther planets that are suitable enugh t supprt life.C. The future f space explratin remains bright.D. After many experiments, they succeeded in making rckets that culd scape Earth’s gravity.
Summarise the main ideaWhen the main idea is nt clearly stated in a tpic sentence, yu shuld read the full paragraph r passage carefully and find the wrds r ideas that repeat themselves. They are likely evidence f the authr’s main idea.
1. Which tw sentences are general statements that culd serve as tpic sentences fr paragraphs?2. Which sentence cntains a linking wrd which indicates that it is part f a list f details?3. Which sentence begins with a sequence wrd shwing that it is prbably a detail frm the middle f a narrative?
SPACE: THE FINAL FRONTIER“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. _____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. ____ On 4 Octber 1957, the Sputnik 1 satellite was launched 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, n20 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 1977t study deep space, and it still transmits data tday.___ 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.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.______ Eurpe, the US, and China all have plans t further study and explre planets like Mars and Jupiter. Despite the difficulties, scientists hpe future discveries will nt nly enable us t understand hw the universe began, but als help us survive well int the future.
Use yur wn wrds t summarise the main idea fr each paragraph.

“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.
Paragraph 1: _____________________________________________________________
Humans have always had a natural curisity abut space.
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 scape Earth’s gravity. On 4 Octber 1957, the Sputnik 1 satellite was launched 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.

Fr example, America’s NASA space agency launched Vyager 1 n 5 September 1977t study deep space, and it still transmits data tday.
Paragraph 2: _____________________________________________________________
Space travel became a reality in the 20th century, with American and Sviet space missins.
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.
Paragraph 3: _____________________________________________________________
Space travel has always invlved great risk, but despite the risks explratin cntinues.
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.
Paragraph 4: _____________________________________________________________
China has made great prgress in space explratin in the early 21st century, becming nly the third cuntry t send humans t space.
The future f space explratin remains bright. Eurpe, the US, and China all have plans t further study and explre planets like Mars and Jupiter. Despite the difficulties, scientists hpe future discveries will nt nly enable us t understand hw the universe began, but als help us survive well int the future.
Paragraph 5: _____________________________________________________________
The future f space explratin lks bright, as many cuntries are planning further missins.
What des the title “Space: The Final Frntier” mean t yu? Share yur ideas with the whle class.
While I supprt space explratin, I dn’t think space is the final frntier just yet. There is still much t learn abut the Earth, and we are nly at the very beginning f new technlgical breakthrughs invlving infrmatin technlgy and AI. There are many scientific and technlgical frntiers all arund us.
What is the authr’s attitude twards space explratin？Hw d yu knw？
The writer feels psitive abut future space explratin and emphasizes this attitude by presenting imprtant events in the histry f space explratin, giving examples, using qutes, and shwing respect and gratitude fr the cntributins scientists and astrnauts have made.
M______ is explring space in the hpe f finding ut mre abut the u______. Hwever, explring space is bth dangerus and challenging.
