人教版英语七年级下册Unit3语法汇总与练习 名词性物主代词与频度副词 第一部分 语法知识点总结 一、物主代词表示所属关系 物主代词用来说明某物属于谁。形容词性物主代词必须放在名词前,名词性物主代词可以单独使用,相当于“形容词性物主代词 + 名词”。 例:This is my basketball. The basketball is mine. 第二句中的 mine 已包含 my basketball 的意思,后面不能再接 basketball。 二、两类物主代词的形式 I — my — mine you — your — yours he — his — his she — her — hers we — our — ours they — their — theirs his 的两种形式相同;hers、ours、yours、theirs 词尾都有 -s,但 mine 没有 -s。its 通常作形容词性物主代词,初中阶段一般不把 its 单独作为名词性物主代词使用。 三、名词性物主代词的句法位置 名词性物主代词可以作主语、表语或宾语。例:Mine is blue.(作主语) The red bike is hers.(作表语) I like yours.(作宾语) 名词性物主代词所代替的名词必须能从语境中明确看出。例:Your exercise habits are different from ours. ours 指 our exercise habits。 不能在名词性物主代词后重复名词。正确:This ruler is mine. 错误:This is mine ruler。 四、频度副词的意义和频率 always 总是,频率最高 usually 通常,频率较高 often 经常,频率中等偏高 sometimes 有时,频率中等偏低 seldom / hardly ever 很少,频率很低 never 从不,频率最低 具体频率会因语境不同而变化,不能把每个副词机械地理解为固定百分比。never 本身已经表示否定,句中通常不再加 not。 五、频度副词的位置和提问 频度副词通常放在实义动词前:I often exercise after school;放在 be 动词后:She is always active;有情态动词或助动词时,放在其后、实义动词前:We can usually finish it. sometimes 的位置较灵活,可放句首、句中或句末。表示具体次数的短语,如 every day、twice a week,常放在句末。 对动作频率提问常用 How often。例:How often do you go swimming? —Twice a week. 六、物主代词与其他代词的区别 1、主格、宾格与物主代词 主格 I / he / they 等作主语,宾格 me / him / them 等作动词或介词的宾语,物主代词说明所属。例:He helps me with my exercise plan. 三种形式各有不同位置。 2、her 和 his 的多种用法 her 可作宾格,也可作形容词性物主代词:I know her. / This is her bag. hers 才是名词性物主代词。his 既可放在名词前,也可单独使用。 3、名词所有格与物主代词 Tom's 和 mine 都可表示所属,但 Tom's 是名词所有格,mine 是名词性物主代词。例:This is Tom's ball. = This ball is Tom's. Tom's 在语境明确时也可单独使用。 七、名词性物主代词的替代范围 1、避免重复名词 The green bike is my bike, and the blue bike is your bike. 可改为 The green bike is mine, and the blue one is yours. 使用代词使表达更自然。 2、指代必须清楚 如果上文没有明确名词,单独使用 mine、hers 等会让读者不知道所指对象。写作时应先出现名词,或使用 one / ones 帮助说明。 3、双重所有格的初步认识 “a + 名词 + of + 名词性物主代词”可表示“……中的一个”,如 a friend of mine。这里不能使用 a friend of my,因为介词 of 后不能只放形容词性物主代词。 八、频度表达的完整体系 1、频度副词与次数短语 always、often 等只给出大致频率;once a week、three times a month 等给出具体次数。两类表达都可回答 How often,但位置不同。 2、every 构成的时间短语 every day、every Friday、every two weeks 表示规律性时间,常用于一般现在时。every 后的可数名词通常用单数,如 every week,而不是 every weeks。 3、hardly ever 与 seldom hardly ever 和 seldom 都表示很低的频率,意义接近否定,通常不再与 not 连用。例:He hardly ever eats fast food. 九、频度副词在句型变化中的位置 1、否定句中的位置 often、usually 等通常放在 don't / doesn't 后、实义动词前:She doesn't often stay up late. never 已有否定意义,不再添加 don't。 2、一般疑问句中的位置 助动词移到句首后,频度副词仍放在主语后、实义动词前。例:Do you often exercise after school? 3、写作中的频度层次 描述运动习惯时,可组合 usually、sometimes、never 和具体次数短语,形成清晰层次。每个频度表达都应与真实动作和时间搭配,避免互相矛盾。 十、常见易错点与判断方法 空格后有名词时通常选择形容词性物主代词;空格后没有名词且需要代替已知事物时,使用名词性物主代词。 安排频度副词位置时,先找谓语:be 后、实义动词前、情态或助动词之后。sometimes 位置灵活,但不要影响句意清楚。 How often 询问频率,How long 询问时长,How many 询问可数名词数量,做题时要根据回答内容反推疑问短语。 第二部分 专项巩固练习题 一、单项选择(15题) 1.
