Space Exploration 太空探索 I have determined to explore space. Being determined to realize my dream, I am determined that no difficulty can defeat me. With determination, I determined on exploring the unknown universe. I once felt disappointed at my poor space knowledge. Disappointed at my weakness and disappointed to find my ignorance, I sighed in disappointment. To my disappointment, many give up their space dreams easily. Humans have a desire for cosmic secrets and have a desire to travel in space. The universe is desirable. We chase our desired journey and strive to meet people’s desires. We desire that space industry (should) develop rapidly. Researchers carry on doing experiments and carry on with tough missions. Faith carries them through countless hardships. We must study independently, stay independent of outside influence and achieve technological independence, not dependent on foreign tech. Progress depends on our efforts. We depend on ourselves to make progress, depend on team cooperation, and depend on it that persistence pays off. It depends on our devotion. Before launch, staff signal to astronauts to prepare and signal full readiness. They send signals to guide crafts. As a noble signal for space exploration, the signals are neither traffic signals nor danger signals, but symbols of human courage. 翻译短文并提取本单元核心词汇、短语，明确其词性、含义及核心搭配 翻译下面的句子： 1. 我决定充分利用每一分钟学习。 2. 她决心克服自己的弱点。 3. 我们决定要按时完成任务。 4. 他对自己的考试成绩感到失望。 5. 听说你放弃梦想，我很失望。 6. 令我失望的是，这场活动被推迟了。 7. 许多年轻人渴望成功与尊重。 8. 他渴望环游世界。 9. 我们希望所有人都参与志愿工作。 10. 遇到困难时也要继续练习。 11. 强大的意志帮他渡过了艰难的时光。 12. 我们指望他按计划完成方案。 13. 你可以相信我们会向你伸出援手。 14. 老师示意我们在课堂上保持安静 Part 2. Self-improvement 自我成长 I once had a lack of self-discipline. For lack of clear goals, I was lacking in learning passion. My spare time was not sufficient for self-improvement nor sufficient to do long-term study tasks. My classmates argued with me about my bad habits. Some argued for strict self-management, while others argued against blind pressure. We once had an argument about study plans, but the value of diligence is beyond argument. Finally, they argued me out of laziness and argued me into making regular progress. Teachers provided guidance for me and provided me with useful methods. The school supplied students with learning resources and supplied rich materials to us. Kind seniors offered advice to me and offered me constant encouragement. I began to attach importance to daily efforts and attach value to persistence. Gradually, I was deeply attached to a positive lifestyle.In the past, my patience easily ran out. I often ran out of courage in difficulty, ran across tricky problems, ran into troubles and blindly ran after instant pleasure. Now I am keen to improve myself and keen on self-struggle. I am keen that I (should) keep moving forward. I am dying to, thirsty for, hungry for, desperate for success and always longing for self-transformation. Bad habits once resulted in poor grades. My early efforts were without result. As a result of my idleness, I fell behind. As a result, I once felt frustrated. I know failure results from lack of effort while success lies in persistence. Many hardships are beyond my power, beyond my reach and beyond my control. My current progress is beyond my expectation, my changes beyond description and beyond belief. I am totally beyond recognition compared with my old self. 翻译下面的句子： 1. 他因缺乏足够经验而失败。 2. 如今年轻人欠缺耐心。 3. 他的勇气足以战胜一切困难。 4. 不要为小事与人争论。 5. 我曾经和最好的朋友吵过架。 6. 我说服他参加了运动会。 7. 我们劝她不要放弃梦想。 8. 学校为学生提供免费书籍。 9. 我们应该重视心理健康。 10. 她深深眷恋自己的家乡。 11. 我们的食物最终耗尽了 12. 我已经花光了零花钱。 13. 他渴望提升自己的英语口语。 14. 粗心常常导致错误。 15. 由于努力，他取得了巨大进步。 16. 他每晚熬夜，结果生病了。 17. 他的成功源于持之以恒的努力。 18. 远方的梦想永远触手可及（并非遥不可及）。 19. 湖景之美难以形容 20. 这个小村庄变得面目全非、认不出来。 必修三 Unit 4 重点词汇课中作业 完整答案 Pre-class：词性转换 1. procedure n. 程序；步骤→process n. 过程 v. 加工 2. mental adj. 精神的；思想的→mentally adv. 精神上；智力上 physical adj. 身体的；物理的→physically adv. 身体上 3. intelligent adj. 聪明的；智能的→intelligence n. 智力；聪明；智能 4. universe n. 宇宙→universal adj. 普遍的；全世界的 5. determine vt. 确定，决定→determined adj. 下定决心的，坚定的→determination n. 决心 6. agency n. 专门机构；代理处→agent n. 代理人 7. transmit v. 传输；发送→transmission n. 传送；传输 8. disappointed adj. 失望的→disappointing adj. 令人失望的→disappoint v. 使失望 →disappointment n. 失望 9. desire n./v. 渴望；欲望→desirous adj. 渴望的，想要的→desirable adj. 令人满意的 10. independent adj. 独立的；自立的→independently adv. 独立地→dependent adj. 依赖的 →dependently adv. 依赖地→independence n. 独立；自主 →dependence n. 依赖；依靠 → depend v. 依赖；依靠 11. recycle vt . 回收利用→ recycling n. 回收利用→ recyclable adj. 可回收的 12. lack n. 缺乏；短缺 v. 没有；缺乏→lacking adj. 不足的；缺少的 13. current adj. 当前的；现在的 n. 水流；电流；流行 →currently adv. 目前；当前→currency n. 货币 14. sufficient adj. 足够的；充足的→sufficiency n. 充足 15. globe n. 地球；地球仪→global adj. 全球的 16. argue v. 争辩；争论→argument n. 争辩 17. analysis n. 分析→ analyse/analyze v. 分析 18. regular adj. 定期的；经常的；正常的→regularly adv. 经常；定期地→irregular adj. 不规律的 19. limited adj. 有限的→unlimited adj. 无限的→limit v. 限制；n. 限制→limitation n. 限制 20. mystery n. 神秘→mysterious adj. 神秘的 21. attach vt. 系；绑；贴；附上→attached adj. 喜爱的；附属的→attachment n. 附属物；附件 While-class Part 1 原文翻译 + 核心词汇短语整理 原文翻译 我决心探索太空。怀揣实现梦想的坚定信念，我坚信没有任何困难能将我击垮。凭着这份决心，我决意去探索未知的宇宙。 我曾经因自己贫乏的太空知识感到失望。苦于自身的短板，又沮丧地发现自己所知甚少，我失望地叹息。令我失望的是，很多人轻易放弃了自己的太空梦。 人类渴望解开宇宙奥秘，向往太空航行。宇宙令人心驰神往。我们追寻心中向往的旅程，努力满足人们的憧憬。我们期盼航天产业飞速发展。 科研人员持续开展实验，攻坚克难完成艰巨任务。心中的信念支撑他们熬过无数磨难。 我们必须自主学习，不受外界干扰，实现科技自主，不依赖国外技术。进步依靠我们自身的付出。我们依靠自己取得进步，依靠团队协作，坚信坚持终有回报。一切都取决于我们的付出。 发射前，工作人员向宇航员示意做好准备，示意全员就绪。他们发送信号引导飞行器。作为太空探索崇高的象征，这些信号既非交通信号灯，也不是危险警示，而是人类勇气的标志。 Part1 核心词汇、短语（词性 + 含义 + 搭配） 单词 1. determine /dɪˈtɜːmɪn/vt. 决定，确定 搭配：determine to do sth 决心做某事；determine on sth 决意某事 2. determined /dɪˈtɜːmɪnd/adj. 坚定的，下定决心的 搭配：be determined to do sth 下定决心做某事；be determined that... 坚信…… 3. determination /dɪˌtɜːmɪˈneɪʃn/n. 决心，毅力 4. universe /ˈjuːnɪvɜːs/n. 宇宙 5. universal /ˌjuːnɪˈvɜːsl/adj. 普遍的，宇宙的 6. disappoint /ˌdɪsəˈpɔɪnt/vt. 使失望 7. disappointed /ˌdɪsəˈpɔɪntɪd/adj.

While-class Part2 原文翻译 + 核心词汇短语整理 原文翻译 我曾经缺乏自律。由于目标模糊，我缺少学习热情。我的课余时间不足以实现自我提升，也不足以完成长期学习任务。 同学们就我的坏习惯和我争论。有人主张严格自律，也有人反对施加无谓压力。我们曾为学习计划发生争执，但勤奋的价值毋庸置疑。最终，他们劝我改掉懒惰，督促我稳步进步。 老师们为我提供指导，传授实用的学习方法。学校为学生配备学习资源，向我们提供丰富资料。热心学长为我提建议，不断给予我鼓励。 我开始重视日常积累，看重坚持的意义。渐渐地，我深深爱上了积极向上的生活方式。从前，我总容易失去耐心，遇到难题就丧失勇气，撞上棘手的题目、陷入麻烦，还盲目追逐即时快感。 如今我渴望自我提升，一心坚持自我奋斗。我迫切希望自己持续前行。我极度渴求成功，始终期盼自我蜕变。 昔日的坏习惯造就了糟糕的成绩。我早年的努力毫无成效。因为懈怠，我落后于人，结果一度十分沮丧。我明白失败源于不够努力，而成功贵在持之以恒。 许多磨难超出我的能力、触及范围与掌控。我当下的进步超乎预料，我的改变难以言表、难以置信。和从前的自己相比，我早已判若两人。 Part2 核心词汇、短语（词性 + 含义 + 搭配） 单词 1. lack /læk/n./v. 缺乏 搭配：for lack of 因缺乏；be lacking in 欠缺…… 2. lacking /ˈlækɪŋ/adj. 缺少的，不足的 3. sufficient /səˈfɪʃnt/adj. 充足的，足够的 搭配：be sufficient for sth 足够应付某事 4. argue /ˈɑːɡjuː/v. 争论，劝说 搭配：argue with sb about sth 和某人争论某事；argue for 支持；argue against 反对；argue sb out of sth 劝某人放弃某事；argue sb into doing sth 说服某人做某事 5. argument /ˈɑːɡjumənt/n. 争论，争辩 搭配：beyond argument 毋庸置疑 6. supply /səˈplaɪ/v./n. 供应 搭配：supply sb with sth = supply sth to sb 向某人提供某物 7. provide /prəˈvaɪd/v. 提供 搭配：provide sb with sth = provide sth for sb 提供某物给某人 8. offer /ˈɒfə(r)/v./n. 主动提供 搭配：offer sb sth = offer sth to sb 主动给予某人某物 9. attach /əˈtætʃ/vt. 附上；重视 搭配：attach importance to 重视；attach value to 看重；be attached to 依恋，喜爱 10. attached /əˈtætʃt/adj. 依恋的，附属的 11. run /rʌn/v. 跑；耗尽；偶遇；追逐 搭配：run out (of sth) 耗尽；run across 偶遇；run into 撞上，陷入；run after 追逐 12. keen /kiːn/adj. 热切的，渴望的 搭配：be keen to do sth 渴望做；be keen on sth 热衷于；be keen that… (should) do 迫切希望…… 13. desire 类同义：be dying to do /be thirsty for /be hungry for /be desperate for /long for 极度渴望 14. result /rɪˈzʌlt/n./v. 结果；导致 搭配：result in 导致；result from 源于；as a result 因此；as a result of 由于；without result 毫无成效 15. current /ˈkʌrənt/adj. 当前的 16. currently /ˈkʌrəntli/adv. 目前 17. beyond /bɪˈjɒnd/prep. 超出 搭配：beyond one’s power 力所不及；beyond one’s reach 够不到；beyond control 失控；beyond expectation 出乎意料；beyond description 难以形容；beyond belief 难以置信；beyond recognition 面目全非 Part2 单句翻译答案 1.
