Writer’s attitude
1. Where is the title “Space: The Final Frontier” adapted from
2. What does the title “Space: The Final Frontier” mean to you
Further Thinking
“Space, the final frontier. These are the voyages of starship Enterprise(进取号星舰), its continuing mission:
to explore strange new worlds,
to seek out new life forms and civilsations,
to boldly（勇敢地） go where no man has gone before.”
——James Kirk (Star Trek星际迷航）
frontier: a border between two countries;
a wilderness at the edge of a settled area or a country;
an undeveloped field of study
final: implying there were other human frontiers before space, such as physical
frontiers( the discovery of America, the Arctic and the deep sea); and scientific
frontiers( advances in medicine and technology)…
Space: the final frontier: Space is the last field that remains mysterious and unknown to
mankind.
While I support space exploration, I don’t think space is the final frontier just yet. There is still much to learn about the earth, and we are only at the very beginning of new technological breakthroughs involving information technology and AI. There are many scientific and technological frontiers all around us.

Para 1
“Are we alone What’s out there ” People have always looked up at the stars and wondered about space. Today, scientists design vehicles to carry astronauts into space to make important discoveries. Space exploration has come a long way, and we now hope to discover other planets that are suitable enough to support life.
Before the mid-20th century, most people felt travelling into space was an impossible dream. However, some scientists were determined to help humans realise their dream to explore space. After many experiments, they succeeded in making rockets that could escape Earth’s gravity. On 4 October 1957, the Sputnik 1 satellite was launched by the USSR and successfully orbited around Earth. Afterwards, the USSR focused on sending people into space, and on 12 April 1961, Yuri Gagarin became the first person in the world to go into space. Over eight years later, on 20 July 1969, American astronaut Neil Armstrong stepped onto the moon, famously saying, “That’s one small step for [a] man, one giant leap for mankind.” Following this, many more goals were achieved. For example, America’s NASA space agency launched Voyager 1 on 5 September 1977 to study deep space, and it still transmits data today. And the International Space Station(1998) has provided a continuous human presence in space, with astronauts from many different countries on board.
