1、Unit 2 Out of this world Extended readingWhy we explore1. Could you analyse the structure and summarize the main idea of each part? Part 1 (Para. 1) Leading to the topic: why we explore Part 2 (Paras. 26) Reasons for space exploration ReadingReadingReasons for spaceexploration It is in our nature to
2、 explore. It enables us to learn more about the origin, evolution, and likely future of the universe. Technologies first researched and developed for space exploration can be used to solve some of the big problems on the Earth. We profit economically from the space industry and it also creates jobs.
3、 It educates and inspires the next generation. 2. Could you summarize the reasons for space exploration mentioned in the article?ReadingWhat is the authors purpose of writing this article?To share his viewpoints about the meaning of humans space exploration and meanwhile to encourage the readers to
4、analyse the issue in a more critical way.1. How does the author lead to the topic in Para. 1? AppreciationPresent some peoples doubts about the significance of space exploration, motivating people to think about why we explore the space.Appreciation2. What kind of methods does the author employ in e
5、ach paragraph to convince readers of the reasons for space exploration? Paragraph TechniquesExamplesPara. 2 QuotingAs Stephen Hawking once said, “Remember to look up at the stars and not down at your feet. Try to make sense of what you see and wonder about what makes the universe exist. Be curious.”
6、Introducing traditional tales That we are fascinated by the sky is evident in ancient tales from around the world, such as that of Chang e.AppreciationParagraphTechniquesExamplesPara. 3Giving examplesWe have confirmed that the Earth is round and that it orbits the Sun.Para. 4Giving examplesOne of th
7、ese is earthquake shock absorbers.For example, liquid hydrogen is a clean alternative energy source that is used widely as rocket fuel Para. 5Giving examplesThere are many support staff on the ground, such as engineers, mechanics and research assistants.3. How do you understand the sentence structur
8、e of the last sentence of Para. 2?AppreciationIt is an inverted sentence. Compared with the original sentence structure, it highlights “great insight”, thus justifying the reason illustrated in Para. 2.With each space mission comes greater insight, thus motivating u s t o c o n t i n u e a l o n g t
9、 h e s a m e p a t h o f a d v e n t u re .4. Could you find the subject in the sentence in Para. 5? Whats the function of the subject? AppreciationThe subject of the sentence is jobs. It is an inanimate sentence (无灵句), which can make the argument impressive.Jobs in the space industry go far beyond
10、the astronauts that receive widespread media coverage. Appreciation5. Could you find out the characteristic of the sentences?The two sentences are parallel. The structure can better attract readers attention and make the argument more convincing. it can be these moments that shape childrens lives fo
11、rever and motivate them to become the scientists and engineers of the future. It is this kind of inspiration that keeps our thirst for knowledge alive and ensures that advances in space exploration and many other fields will continue to be made. Appreciation6. What does Stephen Hawking want to conve
12、y in the sentences? He wants to emphasize the importance of curiosity. Each step further may lead to a great leap in discovering the world.Remember to look up at the stars and not down at your feet. Try to make sense of what you see and wonder about what makes the universe exist. 1. Do you agree or
13、disagree with the authors opinion? Why?DiscussionI agree with the authors opinion. One of the key advantages mentioned in the article is that the exploration of space has brought us technologies that we use in our everyday lives. For example, the small cameras that we find on our mobile devices were
14、 first developed so that they could be used on the spacecraft. Another important advantage the author mentions is that space exploration inspires young people to study hard and build careers in science and engineering. These fields are absolutely crucial for the future of humanity, and space explora
15、tion plays a vital part in this. DiscussionI do not agree with the authors opinion because I believe that the focus should be on developing technology to keep the Earth and all its inhabitants safe and healthy. This planet is our home. Whether or not we might one day travel to and live on another pl
16、anet, I am sure the technology and knowledge we have today would still exist. Besides, I think that preventing climate change is more important than hurrying to make advances in technology that are not necessary for living well on the Earth. 2. Can you predict the future of space exploration?Discuss
17、ionThe future of space exploration will expand our understanding of our role as humans. As space exploration reveals more mysteries, our perspective of our planet and ourselves will change. Past space exploration raised awareness of the need for global solutions to challenges. Furthermore, space exp
18、loration requires global cooperation, which is already practised on the International Space Station. Hopefully, future knowledge will help us understand the importance of working together to solve other problems on the Earth, such as poverty, hunger and war.
