BP26 Discussion 1 T: The article talks about the
12、 advantages of space exploration. Do you agree or disagree with the authors opinion? Why?Sample answer: I agree with the authors opinion. 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 fir
13、st developed so that they could be used on the spacecraft. I do not agree with the authors opinion, because the focus should be on developing technology to keep the Earth and all its inhabitants safe and healthy. I think that preventing climate change is more important than hurrying to make advances
14、 in technology that are not necessary for living well on the Earth.4. CP26 Discussion 2T: Our exploration of space has already taught us many things. What do you think the future of space exploration holds for human understanding? Give reasons for your opinion and support your reasons with evidence.
15、Sample answer:The 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
16、, space exploration requires global cooperation, which is already practised on the International Space Station. Hopefully, future knowledge will help us better understand the importance of working together to solve other problems on the Earth, such as poverty, hunger and war.【设计意图：此处是课文的延伸，是活用课文知识，运

26、d. However, if you can find out the main body of the sentence, it will be much easier for you to understand the whole sentence. Now lets try some sentences.1. The reality is that space exploration is extremely difficult and dangerous, can take a very long time and costs a huge amount of money. (Para
27、. 1)1. The main body of the sentence is “The reality is that” The conjunction “that” guides the predicative clause, in which “space exploration” is subject. After the subject, there is a copula-predicative structure, and two predicate-object structure. 2. Some people believe that while space explora
28、tion expands our understanding of the universe, it is a waste of the public purse and does nothing to enhance the quality of our lives here on the earth. (Para. 1)2. The main body of the sentence is “Some people believe that” The conjunction “that” guides the object clause, which includes an adverbi
29、al clause guided by “while” and a sub-main sentence. 3. With each space mission comes greater insight, thus motivating us to continue along the same path of adventure. (Para. 2)3. This is an inverted sentence with its usual order “Greater insight comes with each space mission” The part “motivating u
30、s to” is present participle used as adverbial.4. The results of these space investigations have made major contributions to an understanding of the origin, evolution and likely future of the universe, such as planets, stars, and all other forms of matter and energy. (Para. 3)4. The main body of the
31、sentence is “The resultshave made major contributions to an understanding ”.5. It is through our research into space that we have confirmed that the Earth is round and that it orbits the Sun. (Para. 3)5. An emphasized pattern “Itthat (first that)” is used in the sentence. The part “through our resea
32、rch into space” is emphasized. The second “that” and the third “that” guide two object clauses. 6. With technologies first discovered and researched in space exploration, we can solve some of the big problems facing mankind, making our lives safer and easier. (Para. 4)6. The main body of the sentenc
33、e is “we can solve some of the big problems” The pattern “with + complex object” is used at the beginning of the sentence. The present participle “facing mankind” modifies problems. The present participle “making our lives safer and easier” modifies “solve”. 7. It is this cycle of inspiration from a
34、dult to child that keeps our thirst for knowledge alive and ensures that advances in space exploration and many other fields are always being made. (Para. 6)7. An emphasized pattern “Itthat (first that)” is used in the sentence. The part “this cycle of inspiration from adult to child” is emphasized.
35、 The second “that” guides object clause. 【设计意图：影响阅读质量还有长句，长句语法结构复杂，但抽出句子主干，句子就容易理解了，此节帮助学生掌握阅读长句的技巧，也有助于学生深度理解课文。】V. Homework1. Watch the micro lesson: How to write a summary. (Optional)2. Finish off B1 in the workbook.1) What are the dangers on Mars?1) To begin with, Mars is extremely cold. Also, i
36、ts atmosphere is rich in carbon dioxide, so people will not be able to breathe. Still, with no magnetic field, Mars is exposed to much higher levels of radiation. 2) Briefly summarize what life on Mars will be like. Include at least three aspects.2) Since Mars has high levels of radiation, people in
37、 Martian cities will probably live underground at first and then above ground. Since it is expensive to send materials to Mars, Martian citizens will have to make good use of the planets resources and manufacture everything they need. Settlers will probably follow a vegan diet. Also, people there will not travel much, because of the radiation. But they may take advantage of Mars low gravity and invent new sports to entertain themselves.
