My answer is yes—it is worth it, and not for the reason most people think. 　　First, space research pays us back in ways we rarely notice. Satellites guide our buses, warn us of typhoons and connect calls across oceans. Materials developed for spacecraft now keep food fresh and make artificial limbs lighter. In other words, the money does not disappear into the sky; it comes back as technology we use every day. 　　Second, exploration is how a species survives. The earth has limited resources and a long history of disasters. Learning to live beyond it is not an escape but an insurance policy for our grandchildren. 　　Of course, there are those who argue that the money should be spent on hospitals and schools. They have a point—but the choice is not either/or. A country can build both, as China has done. The question is not whether we can afford to explore, but whether we can afford to stop. 【学生习作】 Is Space Exploration Worth the Money? 　　Some people think space exploration is a waste of money. I don't think so. I think it is very important. 　　First, it can help us. We use satellites every day. We can watch TV and use maps. This is very good for our life. 　　Second, it is interesting. Many young people like space. They want to be astronauts. It can make them study hard. 　　So I think we should explore space. It is good for us. 【自我修改清单】（写完对照检查） □ 第一段是否明确亮出了立场？ □ 两条理由是否各有“证据”（技术、数据、具体任务）？ □ 是否使用了 First / Second / In other words 等衔接词？ □ 是否承认并回应了反方观点？ □ 有没有用至少一个从句、一个非谓语动词、一个倒装或强调句？ □ 结尾是否有一句有力的收束，而不是简单重复开头？ 九、参考答案 三、话题词块梳理 Ⅰ. 话题词汇 1. astronaut n. 宇航员；航天员 2. satellite n. 卫星；人造卫星 3. launch vt. 发射；发起 4. orbit n. 轨道 vt. 环绕……运行 5. rocket n. 火箭 6. spacecraft n. 航天器；宇宙飞船 7. universe n. 宇宙；天地万物 8. gravity n. 重力；引力 9. capsule n. 太空舱；胶囊 10. mission n. 任务；使命 11. explore vt. 探索；探测 12. exploration n. 探索；探测 13. discovery n. 发现；发觉 14. technology n. 技术；工艺 15. advanced adj. 先进的；高级的 16. achieve vt. 实现；达到 17. achievement n. 成就；成绩 18. challenge n. 挑战；艰巨任务 19. risk n. 风险；危险 20. float vi. 漂浮；浮动 21. transmit vt. 传输；发射 22. probe n. 探测器；探究 23. unmanned adj. 无人的 24. frontier n. 边境；前沿 Ⅱ. 话题词块 1. launch a satellite 发射卫星 2. go into orbit 进入轨道 3. carry out a mission 执行任务 4. in space 在太空中 5. make a breakthrough 取得突破 6. achieve great success 取得巨大成就 7. be proud of 为……自豪 8. make contributions to 为……做出贡献 9. step by step 一步一步地 10. face challenges 面对挑战 11. take risks 冒险 12. be worth doing 值得做 13. in the long run 从长远来看 14. mankind 人类 15. explore the unknown 探索未知 16. have an effect on 对……有影响 17. benefit from 从……中受益 18. in other words 换句话说 19. date back to 追溯到 20. for the first time 首次 21. push the limits of 突破……的极限 22. rely on 依赖；依靠 23. space station 空间站 24. manned space flight 载人航天飞行 25. open up new possibilities 开辟新的可能 26. curiosity 好奇心 27. from generation to generation 一代代地 28. pursue one's dream 追求梦想 29. at the cost of 以……为代价 30. look to the future 展望未来 Ⅲ. 词块升级 1.

I don't think so. I think it is very important. 　　First, it can help us. We use satellites every day. We can watch TV and use maps. This is very good for our life. 　　Second, it is interesting. Many young people like space. They want to be astronauts. It can make them study hard. 　　So I think we should explore space. It is good for us. 【习作点评】 优点：立场明确，两条理由清楚，能举出卫星、地图等生活例子，结构是标准的四段式，没有跑题，语言基本正确。 问题一：理由停留在“有用”“有趣”，没有解释“为什么有用”。“We use satellites every day”只是陈述，应补一句“它们为轮船导航、预警台风，救了很多人”。 问题二：缺少具体事例与数据。全文没有一个年份、一个任务、一项技术，说服力弱；加入“神舟”“北斗”“天宫”等具体名词，分量立刻不同。 问题三：句式单一，全是“主语 + 动词”的短句，没有从句、非谓语和连接词，读起来像罗列清单。 问题四：没有回应反方观点。议论文若不处理“钱不如花在地面”的质疑，立场就显得单薄；应加一句让步再反驳。 【评分标准】（满分15分，按高考应用文评分细则） 档次 分数 评分描述 第五档 13—15分 覆盖全部要点，应用了较多语法结构和词汇，句式有变化，衔接自然，语法和拼写错误极少，完全达到交际目的。 第四档 10—12分 覆盖全部要点，语法结构和词汇能满足任务要求，衔接基本连贯，有少量错误但不影响理解。 第三档 7—9分 基本覆盖要点，语法结构单调，词汇有限，有一些错误，部分内容表达不清。 第二档 4—6分 遗漏较多要点，语法结构单调、词汇项目有限，错误较多，影响理解。 第一档 1—3分 只能写出个别单词，内容太少，无法传达信息。 【写作指导：本单元写作的三个得分点】 得分点一：把“有用”写成“看得见”。写“satellites are useful”是 6 分，写“satellites guide our buses, warn us of typhoons and connect calls across oceans”是 12 分——三个具体场景，胜过十个形容词。 得分点二：议论文要“接住”反方。用 Of course, there are those who argue that… 让步，再用 but the choice is not either/or 反驳，一句就把思维层次拉开。 得分点三：本单元词块要用够。launch a satellite、go into orbit、make a breakthrough、make contributions to、in the long run、explore the unknown 至少出现 5 个，结尾用 The question is not whether…but whether… 收束，气势与逻辑兼备。 学科网（北京）股份有限公司 $
