“Are we alone? What’s out there?” __________(look) up at the stars, people have always wanted to learn more about space, and scientists work hard to find answers. They make vehicles __________(carry) brave people into space to find out the secrets of the universe. They also really wish to discover other planets that are __________(suit) enough to support life.Before the mid-20th century, most people felt travelling into space was __________ impossible dream. However, some scientists __________(determine) to help humans realise their dream to explore space.After many experiments, they succeeded in __________(make) rockets that could escape Earth’s gravity. On 4 October 1957, the Sputnik 1 satellite __________(launch) by the USSR and successfully orbited around Earth. Afterwards, the USSR focused __________ sending people into space, and on 12 April 1961, Yuri Gagarin became the first person in the world __________(go) into space. Over eight years later, on 20 July 1969, American astronaut Neil Armstrong __________(step) onto the moon, famously saying, “That’s one small step for [a] man, one giant leap for mankind.” __________(follow) 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 __________(transmit) data today.Although scientists try to make sure nothing __________(go) wrong, accidents can still happen.All the astronauts on the USSR’s Soyuz 11 and America’s Challenger died during their missions. These disasters made everyone sad and __________(disappoint), but the desire to explore the universe never died. This is __________ people believe in the importance of carrying on space exploration despite the huge __________(risk). An example of this ongoing work is the International Space Station. It orbits Earth and has astronauts from different countries on board, providing a __________(continue) human presence in space.China’s space programme started later than __________(that) of Russia and the US, but it has made great progress in a short time. China became the __________(three) country in the world to independently send humans into space in 2003, when Yang Liwei __________(success) orbited Earth in the Shenzhou 5 spacecraft. Then Shenzhou 6 and 7 completed __________ second manned orbit and the first Chinese spacewalk, __________(follow) by the vehicle Jade Rabbit being sent to the moon to study its surface. After that, China launched the Tiangong 2 space lab __________ space and Tianzhou1 to dock with it. This __________(signal) one step further in China’s plan to establish a space station in the future. More __________(recent), China has sent Chang’e 4 to explore the surface of the far side of the moon to make measurements and __________(observe).The future of space exploration __________(remain) bright.Europe, the US, and China all have plans to __________(far) study and explore planets like Mars and Jupiter. Despite the difficulties, scientists hope future discoveries will not only __________(able) us to understand how the universe began, but also help us survive well into the future.
Present an argument about space exploration
IS EXPLORING SPACE A WASTE OF TIME AND MONEY?
Countries around the globe are spending billions of dollars and lots of time on various space missions, whether to Mars or other planets much further away. _____________________________ ______________________________________(有人認(rèn)為我們應(yīng)該停止浪費(fèi)時(shí)間和金錢來探索太空). Instead, we should feed the world’s poor and find immediate solutions to other problems, such as pollution and fatal diseases. ______________________________________________________________________(然而，其他人則認(rèn)為這是一個(gè)膚淺的觀點(diǎn)，沒有意識(shí)到探索太空對(duì)我們的幫助).Firstly, exploring space _________________________________________________________ (已經(jīng)在消除世界饑餓的斗爭(zhēng)中發(fā)揮了作用). It has directly resulted in the many satellites that now orbit Earth. A number of the satellites ____________________(記錄著……的數(shù)據(jù)) land and weather patterns.

As a result, space-based science has helped farming in its efforts to grow enough food ____________________________________________________(來養(yǎng)活地球上不斷增長(zhǎng)的人口).Secondly, space exploration ____________________________________________________ (促進(jìn)了造福于我們所有人的技術(shù)進(jìn)步). High-end products around the world are made to a higher standard now because of advanced technology which was first created ____________________ __________(以滿足太空探索的需求).

In order to ______________________________________________________(滿足如此迅速增長(zhǎng)的人口), scientists are trying to find other planets that could one day be our new home. The greatest attention at present is on Mars because it is closer to Earth. In the future, humans may live on both planets.In closing, exploring space __________________________________________________(為世界帶來許多不同的好處).
