To calm Rick down, one day his mum came home with a canvas (画布) and paint. “Whenever you feel bad about something, paint it instead of getting angry.” Though not that happy, Rick gave it a try. After creating many paintings, he took his artworks to his mum. “Tell me, Rick. What are these paintings about?” “The first is about how some kids show off their new clothes. The next is about my teacher who always tells me about how I’m doing things wrong. And the last painting is about how one of my classmates said I should change my attitude (态度). They all make me so angry.” Rick’s mum took Rick by her side and told him, “Don’t you see, Rick? You’re getting so angry but you never try to understand why.” Then she explained (解释) carefully, “All the people you were angry at did nothing wrong. The kids were showing off their good clothes but never laughed at you for being poor. Your teacher scolded you but that was because you caused trouble in class. And your classmate was only trying to help you become better.” “Next time you get angry, take a deep breath, walk away and think about the situation. And when you come back, talk to the person you’re angry at. You might calm down in this way.” Rick took his mum’s advice and became less angry. He even started to feel happy around other children. 1．Why did Rick’s mother give him a canvas and paint? A．To celebrate Rick’s birthday. B．To improve Rick’s painting skills. C．To help Rick get away from anger. D．To let Rick learn from great artworks. 2．What does the underlined word “scolded” in Paragraph 5 probably mean? A．建议 B．斥责 C．要求 D．安慰 3．Which of the following is TRUE? A．The kids didn’t laugh at Rick’s clothes. B．The teacher was not strict with Rick. C．The classmates didn’t treat Rick well. D．Rick’s mother got angry with him at last. 4．What are the suggestions of Rick’s mother in Paragraph 6? ①walk away  ②have a talk ③take a deep breath ④keep away from classmates A． ①②④ B．①③④ C．②③④ D．①②③ 5．What does the story tell us? A．Don’t believe a kid’s words. B．Don’t be afraid of being poor. C．See things in a different way. D．Always believe in yourself. 【答案】1.C 2.B 3.A 4.D 5.C 【导语】本文主要讲述了男孩Rick性格易怒，他的母亲通过让他画画和耐心的解释，引导他学会控制情绪并换位思考，最终Rick变得快乐并学会了与他人和谐相处。 【解析】1.第一段开头明确交代了母亲的行为目的：“To calm Rick down, one day his mum came home with a canvas (画布) and paint.”，这直接说明给Rick颜料和画布是为了帮他缓解并远离愤怒。 2.第五段中母亲向Rick解释道：“Your teacher scolded you but that was because you caused trouble in class.”，在学生“制造麻烦”的语境下，老师通常会采取批评教育的行为。由此推断，scolded意为“斥责”。 3.第五段中母亲说道：“The kids were showing off their good clothes but never laughed at you for being poor.”，这句原话直接证明了选项A“孩子们没有嘲笑Rick的衣服”是正确的。 4.第六段中母亲给出了具体的控诉情绪建议：“…take a deep breath, walk away and think about the situation. And…talk to the person…”，其中包含①“走开”、②“谈话”和③“深呼吸”。 5.通读全文，Rick原本认为周围人都在针对他，但在母亲解释了“All the people you were angry at did nothing wrong.”并揭示了他人行为背后的真实意图后，Rick改变了看法并变得快乐。这说明故事告诉我们要学会从不同的角度看问题。 B “Life is full of the unexpected but everything happens for the best.” My mother said whenever I faced disappointment. “If you can carry on, one day something good will happen.” After graduating from college in 1932, I decided to try for a job in radio, then work my way up to a sports announcer (播音员). I took the bus to Chicago and knocked on the door of every station, but I was turned down every time. In one studio (演播室), a nice lady told me that big stations didn’t want to accept inexperienced people—“Go to the countryside and find a small station that’ll give you a chance,” she said. I returned home, Dixon in Illinois. While there were no radio-announcing jobs in Dixon, my father said Smith Ward had opened a store and wanted a local sportsman to manage its sports department. Since I had played high school football in Dixon, I applied. The job sounded just right for me, but I still failed in the interview. At that moment, mom’s words came to my mind: “Everything happens for the best.” Dad offered me the car to look for a job. I tried WOC Radio in Davenport in Iowa. The program director, named Peter MacArthur, told me they had already had an announcer. As I left his office, I felt frustrated. I asked aloud, “How can a man become a sports announcer if he can’t get a job in a radio station?” I was waiting for the lift when I heard MacArthur calling, “What did you say about sports? Do you know anything about football?” Then he made me stand before a microphone (麦克风) and asked me to broadcast an imaginary (想象的) game. As a result, I did a wonderful job and was told to broadcast Saturday’s game! On my way home, I thought of my mother’s words again, “Everything happens for the best. If you can carry on, one day something good will happen. And when it happens, it’ll feel doubly good because of all the hard work you’ve had.” At that moment I knew just what she meant. 6. The writer wanted to be_________. A．a manager B．a sports announcer C．a sportsman D．a radio editor 7. What does the underlined word “turned down” in paragraph 2 most probably mean? A．received B．refused C．shut D．praise 8. Why couldn’t the writer find a job at big radio stations? A．Because he was too young. B．Because he didn’t get college education. C．Because he hadn’t got enough experience. D．Because he had no sports background. 9. From the passage, we can infer that _________. A．the writer did well and got the job at last B．a kind lady offered the writer a job C．the writer found a job and his father gave him a car as a gift D．the writer finally gave up his dream of being a sports announcer 10. What’s the best title of this passage? A．Life Is Full of Disappointment. B．Everything Happens for the Best. C．To Find a Job in Radio Is Difficult. D．Mother’s Advice Is Useless. 【答案】6.B 7.B 8.C 9.A 10.B 【导语】本文是一篇记叙文，讲述了作者大学毕业后立志成为体育播音员，却屡屡遭遇求职失败，在经历电台求职被拒、商店面试失利后，最终在一家电台意外获得广播工作的故事。文章印证了母亲 “一切都是最好的安排” 的信念，告诉我们只要坚持不放弃，历经挫折后终将迎来机遇。 【解析】 6.细节理解题。根据原文 “After graduating from college in 1932, I decided to try for a job in radio, then work my way up to a sports announcer” 可知，作者的目标是成为一名体育播音员。A 项（经理）是商店招聘的岗位，并非作者的志向；C 项（运动员）并非作者的求职目标；D 项（电台编辑）在原文中未提及，无对应依据，故选 B。 7.词义猜测题。根据前文 “knocked on the door of every station”（挨个电台敲门求职）以及后文 “big stations didn’t want to accept inexperienced people”（大电台不愿接受没经验的人）可推测，作者每次都被拒绝了。A 项（收到）与 “求职被拒” 的语境矛盾；C 项（关闭）侧重 “关门” 的动作，不贴合 “求职被拒绝” 的语义；D 项（表扬）与文意完全相反，故选 B。 8.细节理解题。根据原文 “a nice lady told me that big stations didn’t want to accept inexperienced people” 可知，大电台拒绝作者的原因是他缺乏足够的工作经验。A 项（太年轻）在原文中未提及年龄相关问题；B 项（未接受大学教育）与原文 “After graduating from college”（大学毕业后）矛盾；D 项（没有体育基础）与作者曾在高中打橄榄球的背景不符，故选 C。 9.推理判断题。根据原文 “As a result, I did a wonderful job and was told to broadcast Saturday’s game” 可知，作者最终表现出色，成功获得了广播工作；B 项（一位善良的女士给作者提供了工作）错误，女士仅给作者提供了求职建议，并未直接提供工作；C 项（作者找到工作后父亲送他汽车作为礼物）错误，父亲是在作者求职期间主动提供汽车，方便他出行找工作，并非 “找到工作后的礼物”；D 项（作者最终放弃了成为体育播音员的梦想）与原文结局矛盾，作者最终实现了目标，故选 A。 10.主旨大意题。文章始终围绕母亲 “Everything happens for the best”（一切都是最好的安排）的话语展开，通过作者在挫折中坚持、最终获得机遇的经历，印证了这一核心信念。A 项（生活充满失望）仅体现了作者求职过程中的部分遭遇，未涵盖 “坚持获成功” 的核心；C 项（在电台找工作很难）是文章中的具体细节，无法概括全文主旨；D 项（母亲的建议毫无用处）与文章主旨完全相反，母亲的建议是作者坚持下去的精神动力，故选 B。 二、完型填空（本大题共15小题，每小题3分，共计45分） 从A、B、C、D四个选项中，选出空白处的最佳选项。 I strongly believe the right words at just the right time could change someone’s life.

B 【导语】本文是一篇记叙文，讲述了失聪的作者在校遭受嘲笑、功课遇困，却因老师一句肯定重拾自信、改变人生的故事，印证了恰当的鼓励能给困境中的人带来强大力量。 【解析】 11. 考查动词辨析。句意：当我3岁时，父母发现我完全失聪。A. explained（解释）；B. heard（听见）；C. discovered（发现）；D. agreed（同意）。根据常识，父母是通过观察或检查“发现”孩子失聪的事实，符合语境，故选C。 12. 考查形容词辨析。句意：他们决定把我送到一所所有同学听力都正常的学校。A. normal（正常的）；B. poor（差的）；C. strange（奇怪的）；D. special（特殊的）。后文提到“I was the only deaf child”，可知其他同学听力是“正常的”，形成对比，故选A。 13. 考查动词短语辨析。句意：从第一天起，其他孩子经常嘲笑我，给我起外号。A. thought of（想到）；B. laughed at（嘲笑）；C. heard of（听说）；D. looked after（照顾）。根据“called me names”可知，孩子们因作者的助听器和说话方式“嘲笑”他，符合被欺凌的语境，故选B。 14. 考查形容词辨析。句意：小学期间我很担心。A. excited（兴奋的）；B. pleased（高兴的）；C. surprised（惊讶的）；D. worried（担忧的）。结合前文被嘲笑和后文学业困难的描述，作者的情绪应是“担忧的”，故选D。 15. 考查名词辨析。句意：除了与同学相处的问题，我大部分功课也有麻烦。A. practice（练习）；B. experience（经历）；C. progress（进步）；D. trouble（麻烦）。固定搭配“have trouble with”意为“在……方面有麻烦”，符合学业困难的语境，故选D。 16. 考查代词辨析。句意：乔丹老师在数学课上问了我们一个问题。A. us（我们）；B. them（他们）；C. me（我）；D. her（她）。根据后文“I...immediately raised my hand”可知，问题是对全班同学（我们）提出的，故选A。 17. 考查名词辨析。句意：她是个大块头的女人，声音能充满小教室的每个角落。A. body（身体）；B. mouth（嘴）；C. voice（声音）；D. look（外表）。根据“filled every corner of her tiny classroom”可知，能充满空间的是“声音”，故选C。 18. 考查动词辨析。句意：我读了她的嘴唇，立刻举起了手。A. found（发现）；B. read（读取）；C. opened（打开）；D. touched（触摸）。作为失聪孩子，作者通过“读唇语”理解问题，“read her lips”是固定表达，故选B。 19. 考查连词辨析。句意：但当老师叫到我时，我很害怕。A.

As the saying goes, “Time really matters,” and managing it well makes a big difference.Every morning, I make a to-do list and prioritise urgent and important tasks first, like my school homework. I break big assignments into small steps so they’re easier to finish. I also set aside 20 minutes every day for sports and say “no” to useless activities. These methods help me finish work on time and reduce my stress. Now I live a more organised life and have enough time for both study and relaxation. I believe good time management can make our life better. 学科网（北京）股份有限公司 ( 1 )原创精品资源学科网独家享有版权，侵权必究！ 学科网（北京）股份有限公司 $ 编写说明：本套试卷紧扣《英语 基础模块2》（外研版）教材，以教材单元为基准精准覆盖核心考点。 每个单元设置AB卷，A卷为基础巩固卷，侧重基础考点训练，帮助学生扎实掌握知识要点；B卷为能力提升卷，注重知识整合与全面检测，引导学生构建知识网络。模拟实战情境，聚焦解题能力突破，全面提升应试能力与知识应用水平。 《英语 基础模块2》（外研版）《单元过关卷》 Unit 2 Time Really Matters B卷·能力提升 考试时间：40分钟 满分：100分 班级 姓名 学号 成绩 一、阅读理解（每小题4分，共计40分） 从A、B、C、D四个选项中，选出符合题目要求的最佳选项。 A Rick was a young boy who was angry at everything around him.
