Unit2语法专项—— Have got、名词复数、时间介词
全解精讲+分层练习
学习目标
1. 熟练掌握Have got的肯定、否定形式及用法,能准确表达“拥有”含义
2. 牢记名词复数5大变化规则,能正确写出复数形式,区分规则与不规则变化
3. 掌握on/in/at三个核心时间介词的用法,能结合语境灵活运用
4. 能完成填空、选择、句型转换等多样题型,提升语法综合应用能力
语法一:Have got(表示“拥有”)- 核心定义
1. 含义:Have got 表示“拥有、具有”,侧重“所属关系”,口语中使用频繁
2. 用法:可直接替代have,意思完全一致,更简洁自然(美式口语常用)
3. 注意:have got 不能用于进行时、将来时,只能表示“现在拥有”
例:I have a new pen. = I have got a new pen.(两句均表示“我有一支新钢笔”)
拓展:否定句和疑问句中,have got 比 have 更简洁(如haven't got)
Have got - 人称变化及肯定形式
Have got 的肯定形式随主语人称变化,核心是区分单复数人称
1. 第一、二人称及复数:I/You/We/They + have got
例句:I have got a football.(我有一个足球);
They have got new books.
2. 第三人称单数:He/She/It + has got(主语是单数名词也用has got)
例句:She has got a red bag.(她有一个红色的包);
Tony has got a lesson.
记忆技巧:第三人称单数用has got,其余人称均用have got
人称类别 主语示例 搭配形式 例句
第一、二人称及复数 I, You, We, They have got I have got a football.(我有一个足球)
第三人称单数 He, She, It, 单数名词 has got She has got a red bag.(她有一个红色的包)
Have got - 否定形式及缩写
否定形式直接在have/has后加not,缩写形式更常用,避免书写繁琐
1. 第一、二人称及复数:I/You/We/They + have not got = haven't got
例句:We have not got a maths lesson. = We haven't got a maths lesson.
2. 第三人称单数:He/She/It + has not got = hasn't got
例句:She has not got her pen. = She hasn't got her pen.
注意:否定句中,any 可搭配have got,表示“没有任何……”
(如I haven't got any money.)
Have got - 疑问句及回答
疑问句需将have/has提前,回答简洁,无需重复完整句子
1. 一般疑问句:Have/Has + 主语 + got + 宾语?
例:Have you got a ruler (你有一把尺子吗?);
Has he got a dog
2. 肯定回答:Yes, 主语 + have/has.(缩写:Yes, I've got. 口语常用)
3. 否定回答:No, 主语 + haven't/hasn't.(不能说No, I not have got.)
拓展:特殊疑问句:疑问词 + have/has + 主语 + got?
(如What have you got )
Have got - 易错点提醒
1. 第三人称单数误用have got:He have got a book.(正确:has got)
2. 否定形式错误:She not has got a pen.(正确:hasn't got)
3. 疑问句语序错误:You have got a pen
(正确:Have you got a pen )
4. 混淆have和have got:I have got 10 years old.
(错误:I am 10 years old.)
5. 缩写错误:havn't got / hasn't got(正确:haven't got)
小练习(一)- Have got 填空
用have got / has got / haven't got / hasn't got 完成句子
1. My mother ___________ a new phone.
2. We ___________ any lessons on Sunday.
3. ___________ you ___________ a PE lesson today
4. Tom ___________ a basketball, but he ___________ a football.
5. They ___________ three cats.
has got
haven't got
Have got
has got
hasn't got
have got
语法二:名词复数 - 核心定义
1. 含义:当表示“两个或两个以上”的人、事物或地点时,名词需用复数形式
2. 核心作用:明确数量,避免歧义,是英语数量表达的基础
3. 区分:单数名词(1个)→ 复数名词(≥2个),搭配的动词也需对应
例:a book(一本书,单数)→ two books(两本书,复数)
例:The boy is tall.(单数主语,动词用is);
The boys are tall.(复数主语,动词用are)
注意:不可数名词(如water, rice)没有复数形式
名词复数 - 变化规则(一)一般情况及s/x/ch/sh结尾
规则1:一般情况(大部分名词),直接在词尾加 -s
例:classroom → classrooms;book → books;pen → pens
发音提示:清辅音后读/s/(books /b ks/),浊辅音后读/z/(pens /penz/)
规则2:以s, x, ch, sh结尾的名词,词尾加 -es
例:class → classes;box → boxes;watch → watches;brush → brushes
记忆技巧:这类词词尾发音多为“嘶”“嗤”音,加-es更顺口,发音为/ z/
名词复数 - 变化规则(二)辅音+y结尾
规则3:以“辅音字母 + y”结尾的名词,先变y为i,再加 -es
核心:区分“辅音+y”和“元音+y”(a/e/i/o/u是元音)
例:library → libraries(l是辅音,变y为i加es);baby → babies
反例(元音+y):boy → boys;toy → toys(直接加s,不变y)
易错点:story → storys(错误)→ stories(正确);city → citys(错误)→ cities(正确)
记忆口诀:辅音加y,变i加es;元音加y,直接加s
名词复数 - 变化规则(三)f/fe结尾
规则4:以f或fe结尾的名词,先变f/fe为v,再加 -es
例:leaf → leaves;knife → knives;wife → wives;shelf → shelves
记忆口诀:妻(wife)拿小刀(knife),架(shelf)上找树叶(leaf),变f为v再加es
特殊情况(拓展):部分f结尾名词直接加s(无需变v)
例:roof → roofs(屋顶);gulf → gulfs(海湾);belief → beliefs(信念)
注意:这类特殊词数量少,单独记忆即可,无需死记硬背
名词复数 - 变化规则(四)不规则变化
规则5:不规则变化无固定规律,需单独记忆,是易错重点
常见不规则变化(必记):
tooth → teeth(牙齿);foot → feet(脚);man → men(男人);woman → women(女人)
child → children(孩子);mouse → mice(老鼠);sheep → sheep(绵羊,单复数同形)
例句:I brush my teeth every morning.(牙齿用复数teeth)
拓展:单复数同形的词(除sheep):fish(鱼)、deer(鹿)
名词复数 - 易错点提醒
1. 漏加es:class → classs(错误)→ classes(正确);box → boxs(错误)→ boxes(正确)
2. 辅音+y变化错误:family → familys(错误)→ families(正确)
3. f/fe变v错误:knife → knifes(错误)→ knives(正确)
4. 不规则变化混淆:child → childs(错误)→ children(正确)
5. 不可数名词误用复数:water → waters(错误,water表“水”不可数)
6. 单复数同形误用:sheep → sheeps(错误,单复数同形)
小练习(二)- 名词复数填空
写出下列名词的复数形式,注意区分规则与不规则变化
1. box → ___________ 2. baby → ___________ 3. leaf → ___________
4. man → ___________ 5. library → _________ 6. watch → ___________

leaves

语法三:介词 - 核心用法(时间介词)
本单元重点掌握3个时间介词:on、in、at,核心是区分时间范围
1. 共同点:都用于表示“在……时间”,后接时间名词或短语
2. 不同点:时间范围不同,搭配的时间名词也不同,不可混淆
记忆技巧:从小到大记范围——at(具体时刻)→ on(具体某天)→ in(宽泛时间)
例:at 7:00(具体时刻);on Monday(具体某天);in May(宽泛时间)
介词on - 用法详解
on 用于“具体某一天”“星期”“节日”前,时间范围具体、明确
1. 具体星期:on Monday(在周一);on Tuesdays and Fridays(在周二和周五)
2. 具体日期:on May 1st(在5月1日);on October 10th(在10月10日)
3. 节日:on Christmas Day(在圣诞节);on Teachers' Day(在教师节)
4. 固定搭配:on weekdays(在工作日);on the weekend(在周末)
例句:We have PE lessons on Tuesdays.(我们周二有体育课)
介词in - 用法详解
in 用于“宽泛时间”前,时间范围较大,不具体到某一天
1. 月份:in January(在一月);in May(在五月)
2. 季节:in spring(在春天);in autumn(在秋天)
3. 年份:in 2024(在2024年);in 2025(在2025年)
4. 泛指的上午/下午/晚上:in the morning;in the afternoon;in the evening
例句:We play sports outside in the afternoons.(我们下午在外面做运动)
介词at - 用法详解
at 用于“具体时刻”前,时间范围最窄,精确到小时、分钟
1. 具体时刻:at 6 o'clock(在六点);at 8:30(在八点半)
2. 固定搭配:at noon(在中午);at night(在晚上);at midnight(在午夜)
3. 注意:at 不用于星期、月份前,避免混淆
例句:I get up at six o'clock every morning.(我每天早上六点起床)
易错点:in 6 o'clock(错误)→ at 6 o'clock(正确)
时间介词 - 对比总结
介词 时间范围 搭配示例
on 具体某一天、星期、节日 on Monday;on May 1st
in 月份、季节、年份、泛指上/下午/晚上 in May;in the morning
at 具体时刻、固定搭配 at 7:00;at noon
记忆口诀:具体某天用on,宽泛时间用in,具体时刻用at
介词 - 易错点提醒
1. 星期前误用in:in Monday(错误)→ on Monday(正确)
2. 具体时刻误用in:in 8 o'clock(错误)→ at 8 o'clock(正确)
