A. Your dreams are not important B. You can learn from other people's jobs C.

His job is exciting. （2）描述职业时，常将形容词性物主代词与工作名词搭配。例如：The doctor's name is Wang Li. Her patients trust her. 其中 her 后接名词 patients，表示“她的病人”。 （3）注意不要漏掉名词，也不能用名词性物主代词替代。错误示范：This is my. 正确表达：This is my book. 2. 名词性物主代词相当于“物主代词+名词” （1）名词性物主代词可以独立使用，相当于“形容词性物主代词+名词”，避免重复。常见形式有 mine, yours, his, hers, its, ours, theirs。例如：My job is teaching. What about yours? （2）形容词性物主代词后必须接名词，而名词性物主代词后面不能再接名词。例如：This is my uniform. 与 This uniform is mine. 意思相同，但结构不同。 （3）在上下文明确时，名词性物主代词可以使表达更简洁。例如：a nurse's duty is to care for patients. Mine is to teach students. 3. 名词所有格用 ’s 或 s’ 表示所属关系 （1）名词所有格表示“某人的”或“某物的”。单数名词或不以 s 结尾的复数名词后加 ’s，例如 the doctor's office；以 s 结尾的复数名词后只加 ’，例如 the teachers' room. （2）常用来表达职业场所或职责。例如：The nurses' lounge is on the third floor. （3）注意不要将 ’s 与复数形式混淆。例如，teachers' room 表示“教师办公室”，而 teacher's room 表示“一位教师的房间”。要根据单复数选择正确形式。 4. 可用于描述职业、职责和人物关系 （1）在谈论 Jobs 话题时，常用形容词性物主代词、名词性物主代词和名词所有格来说明人物身份、职责和人际关系。例如：My mother is a nurse. Her job is to take care of patients. That stethoscope is hers. （2）这些所有格表达可以帮助我们明确职业归属，例如：A chef's knife is an important tool. Their work requires teamwork. 三、单项选择（共60题） 从每小题所给的四个选项中，选出一个最佳答案。 1.

My mother is a nurse, and ____ duties include taking care of patients at night. A. she B. hers C. her D. herself 【答案】C 【知识点】形容词性物主代词 her 后接名词 duties，表示所属关系。 【解析】空格后是名词 duties，需要形容词性物主代词修饰，表示“她的职责”。选项 C. her 是形容词性物主代词，正确。选项 A. she 是主格人称代词，不能作定语；选项 B. hers 是名词性物主代词，后面不能接名词；选项 D. herself 是反身代词，不符合句意。因此答案为 C。 2. This is not my pencil case; ____ is the blue one on the teacher's desk. A. My B. Mine C. Me D. Myself 【答案】B 【知识点】名词性物主代词 mine 相当于 my pencil case，在句中作主语。 【解析】空格处作主语，指代“我的铅笔盒”，后面没有名词，所以用名词性物主代词 mine。选项 B. Mine 正确。选项 A. My 是形容词性物主代词，后面必须接名词；选项 C. Me 是宾格人称代词，不能作主语；选项 D. Myself 是反身代词，不符合句意。因此答案为 B。 3. The ____ job is to keep the city safe, and they work very hard. A. police officer B. police officer's C. police officers' D. police officers 【答案】C 【知识点】复数名词所有格 police officers' 表示警察们的工作，注意 s' 形式。 【解析】空格后接名词 job，需要名词所有格表示“警察们的工作”。句子后文 they 表明是复数，所以用复数名词所有格 police officers'。选项 C. police officers' 正确。选项 A. police officer 是名词原形，不能表示所属；选项 B. police officer's 是单数所有格，与 they 不一致；选项 D. police officers 是复数名词，没有所有格，不能修饰 job。因此答案为 C。 4. My aunt is a teacher, and ____ students all respect her very much. A. she B. her C. hers D. herself 【答案】B 【知识点】形容词性物主代词 her 修饰 students，用于描述职业和人物关系（师生关系）。 【解析】空格后是名词 students，需要形容词性物主代词表示“她的学生们”，描述老师和学生之间的关系。选项 B. her 正确。选项 A. she 是主格代词，不能作定语；选项 C. hers 是名词性物主代词，后面不能接名词；选项 D. herself 是反身代词，不符合句意。因此答案为 B。 5. Our neighbours are both doctors, and ____ son wants to become a doctor too. A. themselves B. they C. theirs D. their 【答案】D 【知识点】形容词性物主代词 their 后接名词 son，表示所属关系。 【解析】空格后是名词 son，需要形容词性物主代词 their 表示“他们的儿子”。选项 D. their 正确。选项 A. themselves 是反身代词；选项 B. they 是主格人称代词；选项 C. theirs 是名词性物主代词，后面不能接名词。因此答案为 D。 6. If you need a visitor pass, ____ at the front desk can help you. A. Someone B. My C. Mine D. Yours 【答案】A 【知识点】不定代词 someone 作主语指人；与本单元名词性物主代词（mine, yours）作对比，后者通常指物且不能指人，不能作本句主语。 【解析】空格处需要主语，指“某个人”，Someone 是不定代词，作主语表示不确定的人，符合句意。My 是形容词性物主代词，后必须接名词，不能单独作主语；Mine 和 Yours 是名词性物主代词，通常指物不指人，且这里“我的东西/你的东西”在办公前台不能帮助人，逻辑不通。应选 A。 7. This is ____ office, and he welcomes every visitor with a smile. A. Mr. Chen's B. Mr. Chen C. Mr. Chens D. Mr. Chens' 【答案】A 【知识点】名词所有格用 ’s 表示所属关系，单数名词加 ’s。 【解析】空格后是名词 office，需要表示“陈先生的办公室”，应该用名词所有格 Mr. Chen's。B 没有所有格，不能修饰名词；C 是复数形式但未加所有格；D 是复数所有格，但这里指一个人，且“陈先生们”不合理。应选 A。 8. Many people agree that a nurse's work is ____ important as a doctor's in the hospital. A. as B. than C. my D. mine 【答案】A 【知识点】as ... as ... 表示同级比较；与本单元目标“可用于描述职业、职责和人物关系”作对比，本句在比较护士和医生的工作重要性。 【解析】as...as 是同级比较结构，第一个 as 后接形容词原级，表示“和……一样重要”。than 用于比较级；my 和 mine 是物主代词，不能修饰形容词 important，且这里不需要表示所属，而需要连接比较结构。应选 A。 9. ____ job is to take care of sick animals at the pet clinic. A. Her B. She C. Hers D. He 【答案】A 【知识点】形容词性物主代词后接名词，如 my job, her duty。 【解析】空格后是名词 job，需要用形容词性物主代词来修饰，Her 是形容词性物主代词，意为“她的”，Her job 表示“她的工作”。She 和 He 是人称代词主格，不能修饰名词；Hers 是名词性物主代词，后不能接名词。应选 A。 10. My little sister ____ her room because our cousins are coming this afternoon. A. is cleaning B. cleans C. clean D. cleaned 【答案】A 【知识点】现在进行时表示此刻正在发生的动作，结构为 am/is/are + doing；与本单元目标“名词性物主代词相当于“物主代词+名词”，如 mine, yours”作对比，本句需要用动词形式表达动作，而非物主代词。 【解析】句末时间提示 this afternoon 且 because 从句用现在进行时 are coming 表示将来计划，主句强调当前正在进行的动作，故用现在进行时 is cleaning。cleans 是一般现在时，表示习惯；clean 原形缺少助动词；cleaned 是一般过去时，与当前语境不符。应选 A。 11. Next term, my brother ____ help at the local hospital as a volunteer. A. his B. will C. he's D. is 【答案】B 【知识点】实际正确答案考查 will 表示将来的动作，对比目标为名词所有格用 ’s 或 s’ 表示所属关系。 【解析】空格后是动词原形 help，需要助动词 will 构成一般将来时，表示将来的动作；his 是物主代词，不能作助动词；he's 是 he is 或 he has 的缩写，不能直接接动词原形；is 是 be 动词，也不能接动词原形。名词所有格如 Tom's 表示所属，不能用于此结构，学习者容易混淆。故正确答案是 B. will。 12. My father is a doctor, and ____ patients trust him very much every day. A. he B. his C. he's D. him 【答案】B 【知识点】可用于描述职业、职责和人物关系 【解析】句意为“我的父亲是一名医生，他的病人每天都非常信任他。”空格后是名词 patients，需要形容词性物主代词 his 作定语，表示所属关系；he 是主格代词，不能作定语；he's 是 he is 的缩写，不能修饰名词；him 是宾格代词，也不能修饰名词。故正确答案是 B. his。 13. The young nurse ____ works in this hospital is very kind to every patient. A. whose B. who C. which D. she 【答案】B 【知识点】实际正确答案考查关系代词 who 引导定语从句，对比目标为形容词性物主代词后接名词。 【解析】空格所在句子为定语从句，先行词 nurse 指人，关系代词 who 可作主语引导从句；whose 虽可表示所有，但后面需接名词，而此处后面是动词 works；which 指物，不适用于人；she 不能引导定语从句。形容词性物主代词如 my 后须接名词，与关系代词 who 的用法不同，容易混淆。故正确答案是 B. who。 14. This is not my pencil case; ____ is on the desk over there. A. my B. mine C. me D. I 【答案】B 【知识点】名词性物主代词相当于“物主代词+名词”，如 mine, yours 【解析】空格后没有名词，且句意为“这不是我的铅笔盒，我的在那边桌上”，需用名词性物主代词 mine 作主语，相当于 my pencil case；my 是形容词性物主代词，后须接名词；me 是宾格代词，I 是主格代词，均不能单独充当主语。故正确答案是 B. mine。 15. My sister and I often help ____ parents with housework on weekends at home. A. Tom's B. our C. ours D. us 【答案】B 【知识点】实际正确答案考查形容词性物主代词 our 的用法，对比目标为名词所有格用 ’s 或 s’ 表示所属关系。 【解析】主语 My sister and I 是第一人称复数，空格后 parents 是名词，需用形容词性物主代词 our 修饰；ours 是名词性物主代词，不能接名词；us 是宾格代词，不能作定语；Tom's 是名词所有格，表示 Tom 的，与主语不符。名词所有格 Tom's 与物主代词 our 都表所属，但此处需用与主语一致的物主代词。故正确答案是 B. our。 16. My sister and I are both nurses. ____ work in the same hospital. A. Our B. We C. Ours D. Us 【答案】B 【知识点】人称代词主格作主语（与形容词性物主代词、名词性物主代词和宾格辨析；结合 Unit 3 描述职业和人物关系） 【解析】正确答案 B (We)。空格后是动词 work，需要人称代词主格作主语。We 是主格，表示“我们工作”，符合语境。选项 A Our 是形容词性物主代词，后面必须接名词，不能单独作主语；选项 C Ours 是名词性物主代词，通常指代物，不能指代人作主语；选项 D Us 是宾格，不能作主语。本题同时辨析 Unit 3 中物主代词用于描述职业职责的用法，此处需要主格代词。 17. My mother is a teacher, and ____ job is to help young students learn English well. A. she B. her C. hers D. herself 【答案】B 【知识点】形容词性物主代词后接名词（如 her job） 【解析】正确答案 B (her)。空格后是名词 job，需要用形容词性物主代词修饰，her job 意为“她的工作”。选项 A she 是人称代词主格，不能修饰名词；选项 C hers 是名词性物主代词，后面不能再接名词；选项 D herself 是反身代词，不能作定语修饰名词。本题考点为形容词性物主代词后接名词，如 my job, their duties。 18. Look at this photo of my family. ____ is my brother, Tom, and that is his friend. A. Mine B. Yours C. This D. Hers 【答案】C 【知识点】指示代词 this 用于指代近处的人或物（与名词性物主代词辨析；结合 Unit 3 描述人物关系） 【解析】正确答案 C (This)。句意为“看这张我家的照片。这是我哥哥汤姆，那是他的朋友。” 空格处需要指示代词 this 指代照片中近处的人。选项 A Mine、B Yours、D Hers 均为名词性物主代词，不能独立作主语指代人。本题辨析指示代词 this 与名词性物主代词在结构和功能上的差异。 19. Tom is a good doctor, and this is ____ office on the third floor of the hospital. A. Tom’s B. Tom C. Toms D. Toms’ 【答案】A 【知识点】名词所有格（单数名词加 ’s 表示所属关系） 【解析】正确答案 A (Tom’s)。空格后是名词 office，表示“汤姆的办公室”，需要用名词所有格。单数名词 Tom 后加 ’s 构成所有格。选项 B Tom 是名词原形，不能表示所属；选项 C Toms 是复数形式，不符合单数语境；选项 D Toms’ 是复数所有格，但主语是单数 Tom，与谓语 is 不一致。本题考点为名词所有格用 ’s 表示所属关系。 20. There are many jobs in the hospital. Some doctors work in the daytime, and ____ work at night. A. other B. others C. another D. the other 【答案】B 【知识点】不定代词 others 表示“其他一些”，作主语（与 Unit 3 描述职业和职责作相似结构辨析） 【解析】正确答案 B (others)。句意为“医院里有很多工作。一些医生白天工作，其他一些医生晚上工作。” others 是不定代词，表示“其他一些”，作主语，谓语动词用复数 work，符合语境。选项 A other 是形容词，不能单独作主语；选项 C another 表示“另一个”，是单数，不能与复数谓语 work 连用；选项 D the other 通常指两者中的另一个，这里上下文并未限定只有两个，所以不合适。本题辨析不定代词与 Unit 3 描述职业职责的物主代词用法。 21. ____ of my two best friends are good at English, and they often help me with my homework. A. Both B. Either C. All D. Their 【答案】A 【知识点】实际考查不定代词 both 表示“两者都”的用法，并与形容词性物主代词 their 作辨析；形容词性物主代词后应直接接名词，不能接 of 短语。 【解析】Both 表示“两者都”，与后面的 two best friends 和复数谓语 are 及 they 一致，故选 A。Either 表示“两者中的任意一个”，作主语时谓语通常用单数，且与 often help 矛盾；All 通常用于三者或三者以上；Their 是形容词性物主代词，不能用于 of 结构前。 22. I forgot to bring my dictionary, so may I use ____ for today's English class? A. your B. yours C. my D. mine 【答案】B 【知识点】考查名词性物主代词相当于“物主代词+名词”，如 yours 相当于 your dictionary，可在句中作宾语；形容词性物主代词不能单独使用。 【解析】yours 是名词性物主代词，相当于 your dictionary，可作 use 的宾语，故选 B。your 和 my 是形容词性物主代词，不能独立作宾语；mine 虽然也是名词性物主代词，但意思是“我的”，与语境中向对方借词典的事实不符。 23. ____ of the two drivers' cars could start this morning, so they both took the bus. A. Neither B. None C. No D. Drivers' 【答案】A 【知识点】实际考查不定代词 neither 表示“两者都不”的用法，并与名词所有格如 drivers' 作辨析；名词所有格通常表示所属关系，不能单独作主语。 【解析】Neither of + 复数名词表示“两者都不”，谓语动词通常用单数，符合语境，故选 A。None 常用于三者或三者以上；No 不能与 of 连用；Drivers' 是名词所有格，不能单独作主语，也不能与 of 短语直接搭配。 24. Lily and Lucy are twin sisters, and ____ parents both work as English teachers. A. Their B. Theirs C. Lily's and Lucy's D. Them 【答案】A 【知识点】考查运用形容词性物主代词描述人物职业和家庭关系，Their 表示“他们的”，修饰 parents，说明他们的父母都是英语老师。 【解析】Their 是形容词性物主代词，修饰 parents，符合描述人物关系的需要，故选 A。Theirs 是名词性物主代词，不能作定语修饰名词；Lily's and Lucy's 虽然也是所有格，但表达冗长且不如 Their 自然；Them 是宾格代词，不能作定语。 25. ____ is your mother's job? She works as a nurse in a big hospital. A. What B. Whose C. Who D.

My brother's dream is to be a pilot, while ________ is to be a nurse. A. my B. mine C. me D. myself 【答案】B 【知识点】名词性物主代词 mine 作主语，相当于 my dream 【解析】空格处需要名词性物主代词作主语，相当于 my dream，所以用 mine。my 是形容词性物主代词，后面必须接名词，不能单独作主语；me 是人称代词宾格；myself 是反身代词，均不符合语境。 27. There are ________ interesting jobs in the new technology company, so many people want to work there. A. some B. any C. my D. manager's 【答案】A 【知识点】不定代词 some 用于肯定句表示“一些”；与名词所有格辨析：无所属关系，故不用 's 所有格 【解析】肯定句用 some 表示“一些”；any 多用于否定句和疑问句；my 是形容词性物主代词，后需接名词，且语义不合；manager's 是名词所有格，后需接名词，但此处无名词，且句子不表示所属关系。本题对比不定代词 some 与名词所有格，所有格需表示“某人的”，而此处没有这种含义。 28. ________ in our class has finished the homework yet, so the teacher is very angry. A. Somebody B. Anybody C. Nobody D. Everybody 【答案】C 【知识点】复合不定代词 nobody 本身表否定，用于形式上肯定的句子；与职业/职责描述辨析：本句并非描述职业关系，而是强调“没有人” 【解析】yet 通常用于否定句或疑问句，nobody 本身具有否定意义，句子意思是“还没有人完成作业”，符合语境。somebody 和 everybody 多用于肯定句，与 yet 不搭配；anybody 虽然用于否定句或疑问句，但需与否定词连用，不能单独表达否定。本题对比复合不定代词与描述职业、职责的句型，后者通常用所有格或物主代词，此处不适用。 29.

A. my B. mine C. me D. our 【答案】A 【知识点】形容词性物主代词 my 后接名词 colleague 【解析】my 是形容词性物主代词，后面接名词 colleague，表示“我的新同事”。mine 是名词性物主代词，不能接名词；me 是人称代词宾格，不能作定语；our 虽然也是形容词性物主代词，但句子主语是 I，说话者说的是“我的新同事”，our 不符合语境。 30.

The children ____ singing an English song happily in the music room right now. A. are B. their C. ours D. they 【答案】A 【知识点】现在进行时 be + doing（六年级上 Unit 2）；与 Unit 3 形容词性物主代词后接名词作相似结构辨析：their/ours 等不能用于 be 动词位置 【解析】句中的 Listen! 和 right now 提示正在进行的动作，需要现在进行时 be + doing，主语 The children 后应填 are。their 和 ours 是物主代词，后需接名词，不能与 singing 构成谓语；they 是主格代词，若填入则造成主语重复，句子结构错误。本题通过选项对比帮助区分物主代词和现在进行时的核心结构。 58. I can't find my job list in my bag. Can you show me ____, please? A. your B. yours C. my D. mine 【答案】B 【知识点】名词性物主代词 yours 相当于 your + 名词，可独立使用 【解析】空格后没有名词，因此需要名词性物主代词，指代 your job list，故选 yours。your 和 my 是形容词性物主代词，后面必须接名词；mine 虽为名词性物主代词，但与第一人称主语不一致，不符合语境。本题巩固名词性物主代词独立使用的特点。 59. Next term, our head teacher ____ give us more chances to try different jobs. A. will B. teacher's C. head teacher's D. teachers' 【答案】A 【知识点】will 表示将来（六年级下 Unit 1）；与 Unit 3 名词所有格作相似结构辨析：teacher's 等不能直接后接动词原形 【解析】句中的 Next term 表明动作发生在将来，结构为 will + 动词原形，故填 will。teacher's、head teacher's 和 teachers' 都是名词所有格，后需接名词，不能直接与 give 构成谓语，填入后句子缺少谓语动词。本题通过选项对比帮助学生区分将来时助动词 will 与名词所有格的不同功能。 60. My ____ job is to teach English in a middle school, and she likes it very much. A. sister's B. sisters C. sister D. sisters' 【答案】A 【知识点】名词所有格 sister's 表示所属关系，用于描述职业和人物关系 【解析】空格后是名词 job，且后文用 she 指代单数姐姐，因此需要单数名词所有格 sister's，表示“姐姐的工作”。sisters 是复数名词，sister 是单数名词，均不能直接作定语表示所属；sisters' 是复数所有格，与后文 she 不一致。句子描述姐姐的职业，符合 Unit 3 使用名词所有格描述职业和人物关系的语法目标。 四、语法选择（共10分） 请通读下面短文，掌握其大意，根据语法和上下文连贯的要求，从每小题所给的四个选项中选出一个最佳答案。 My name is Li Hua.
