译林版英语五年级上册 Unit 1 Good habits 常考易错语法专项练习 第一部分：常考易错语法梳理与对应练习 本单元围绕“生活习惯”主题展开，核心语法包括一般现在时第三人称单数、频度副词的用法、祈使句的否定形式、have/has 的用法区别以及介词 at / in / on 在时间短语中的运用。 易错总结（考前必看）： -第三人称单数加 -s/-es：看到 He/She/It/单数名词，动词要变形！记住口诀：三单动词加 -s，o/s/x/sh/ch 加 -es。 -have / has 区别：三单用 has，其他用 have。有 Does 时用 have 原形。 -Do / Does 引导的疑问句：Does 后面动词用原形，不加 -s！如 Does he have...? -频度副词位置：放在实义动词前（如 always go），be 动词后（如 is never）。 -祈使句否定：Don't + 动词原形，主语 you 省略。 -时间介词口诀：at 具体时刻，on 具体某天，in 宽泛时间（月/季/年份/上下午）。 易错语法一：一般现在时第三人称单数（-s/-es 的添加） 核心要点： - 当主语是he / she / it或单数名词/人名时，一般现在时的动词要加 -s 或 -es，这是本单元最重要的语法点。 - 一般情况加 -s：get → gets，help → helps，read → reads。 - 以 s / x / sh / ch / o 结尾的动词加 -es：brush → brushes，wash → washes，watch → watches，go → goes，do → does。 - 以“辅音字母 + y”结尾的动词，变 y 为 i 再加 -es：study → studies，fly → flies，carry → carries。 - have 是特殊变化，变为 has。 - 主语为第一人称（I / we）、第二人称（you）或复数主语时，动词用原形。 常见错误示例： - ❌ He get up at 6:30.（主语 he 是第三人称单数，缺少 -s） - ✅ He gets up at 6:30. - ❌ She go to school on foot.（缺少 -es） - ✅ She goes to school on foot. 对应练习一：用所给词的适当形式填空（10分） 1. My brother __________ (get) up early every day. 2. She __________ (brush) her teeth twice a day. 3. He __________ (go) to school on foot. 4. Mary __________ (have) a good habit. 5. My father __________ (watch) TV in the evening. 6. The cat __________ (like) to sleep on the sofa. 7. She __________ (study) hard at school. 8. He __________ (wash) his hands before meals. 9. I __________ (read) books every day. 10. They __________ (finish) their homework on time. 易错语法二：频度副词的用法及位置 核心要点： - 本单元重点掌握的频度副词有：always（总是） > usually（通常） > often（经常） > sometimes（有时） > never（从不）。 - 频度副词通常放在实义动词之前，be动词 / 助动词之后。 - 对频度副词提问用How often，但本单元要求不高，了解即可。 举例： - I always get up early.（放在实义动词 get 之前） - She is never late for school.（放在 be 动词 is 之后） - He often helps his mother.（放在实义动词 helps 之前） 对应练习二：选择正确的频度副词填空（10分） （A）用 always / usually / often / sometimes / never 填空。 1. I __________ get up at 7:00. I'm never late. 2. She __________ helps her mother do housework, but not every day. 3.They____ go to the park on Sundays,but sometimes they stay at home. 4. He is __________ late for school. He is always on time. 5. We __________ have breakfast at 7:30. That's our habit. （B）将下列句子中的频度副词放到正确的位置。 6. She helps her mother. (always) ________________________________________________ 7. He is late for school. (never) ________________________________________________ 8. We go to the library. (often) ________________________________________________ 9. They eat breakfast. (usually) ________________________________________________ 10. I am happy. (always) ________________________________________________ 易错语法三：祈使句的否定形式 核心要点： - 祈使句用于表达命令、请求或建议，以动词原形开头，主语 you 通常省略。 -肯定形式：动词原形 + 其他。如：Brush your teeth. / Get up early. -否定形式：Don't + 动词原形 + 其他。如：Don't go to bed late.（不要晚睡。） -祈使句的否定形式中，Don't 后面必须接动词原形，不能加 -s 或 -es。 常见错误示例： - ❌ Don't plays in the street.（多了 -s） - ✅ Don't play in the street. 对应练习三：按要求完成句子（10分） 1. Get up early.（改为否定句） ________________________________________________ 2. Don't watch TV too much.（改为肯定句） ________________________________________________ 3. 用祈使句表达“不要晚睡”。 ________________________________________________ 4. 用祈使句表达“请保持房间整洁”（肯定形式）。 ________________________________________________ 5. Please brush your teeth.（改为否定句） ________________________________________________ 易错语法四：have / has 的用法区别 核心要点： - have：主语是 I / you / we / they 或复数名词时使用。 - has：主语是 he / she / it 或单数名词/人名时使用。 - 注意：当句子中出现助动词do / does / don't / doesn't时，后面用 原形 have。 -have/has 表示“拥有”或用于固定短语中，如 have breakfast / have lunch / have dinner。 常见错误示例： - ❌ He have a good habit.（主语 he 应用 has） - ✅ He has a good habit. - ❌ Does he has breakfast at home?（加了 Does，has 要变回 have） - ✅ Does he have breakfast at home? 对应练习四：用 have 或 has 填空（10分） 1. I __________ a good habit. 2. She __________ a pet cat. 3. We __________ breakfast at 7:00. 4. He __________ lunch at school. 5. They __________ a big house. 6. My father __________ a car. 7. __________ you got any new books? 8. Does she __________ a brother? 9. The dog __________ a long tail. 10. My parents __________ dinner at 6:30. 易错语法五：介词 at / in / on 在时间短语中的运用 核心要点： -at：用于具体时刻点。如：at 6:30（在六点半），at noon（在中午），at night（在夜里）。 -in：用于月份、年份、四季或一天中较宽泛的时间段。如：in the morning（在早上），in 2024，in July，in spring。 -on：用于具体的某一天或某一天的早/午/晚。如：on Monday（在周一），on Sunday morning（在周日早上）。 常见错误示例： - ❌ I get up in 7:00.（具体时刻点用 at） - ✅ I get up at 7:00. - ❌ She goes to school on the morning.（泛指的上午用 in） - ✅ She goes to school in the morning. 对应练习五：用 at / in / on 填空（10分） 1.
