寒假预习:专题10 Unit 5 Farms and us语法讲义+知识演练
2025-2026学年四年级下册英语(人教版)
Unit 5 核心语法讲义
语法点1:可数名词复数
1. 讲解:表示两个或两个以上的人或事物,名词需要变复数;本单元重点是农场动物、蔬菜类名词的复数变化,分3种情况。
2. 分类+课本原句例句
(1)一般情况:直接加s(最常用)
例:cow → cows(奶牛)、horse → horses(马)、bee → bees(蜜蜂)
课本原句:I have a lot of animals. Cows, horses, sheep, pigs and chickens.(我有很多动物。奶牛、马、绵羊、猪和鸡。)
(2)特殊变化:单复数同形(易错点)
例:sheep → sheep(绵羊)、fish → fish(鱼)
课本原句:How many sheep do you have?(你有多少只绵羊?)(注意:不用sheeps)
(3)以o结尾的名词:加es(本单元重点)
例:tomato → tomatoes(西红柿)、potato → potatoes(土豆)
课本原句:What are these? They’re tomatoes.(这些是什么?它们是西红柿。)
3. 易错提示:不要把sheep写成sheeps,不要把tomato复数写成tomatos
语法点2:How many引导的特殊疑问句(重点,询问数量)
1. 讲解:用来询问“可数名词的数量”,回答用具体数字,句式固定,后接可数名词复数。
2. 固定句式
问句:How many + 可数名词复数 + do you have?(你有多少……?)
答句:I have + 具体数字. / I have ... (数量相关表达)。
3. 课本原句例句
问句:How many cows do you have?(你有多少头奶牛?)
答句:I have 20.(我有20头。)(课本原句,最基础答法)
拓展例句:--How many tomatoes do you have? --I have 15.(你有多少个西红柿?我有15个。)
4. 易错提示:How many后面必须接名词复数(如cows,不能说How many cow)。
语法点3:What are these/those? 的问答(区分近处/远处物品)
1. 讲解:用来询问“多个物品是什么”,these指代“近处的物品”(离说话人近),those指代“远处的物品”(离说话人远),回答句式固定。
2. 固定句式
(1)询问近处物品:What are these? → They’re + 复数名词.(这些是什么?它们是……。)
课本原句:What are these? They’re tomatoes.(这些是什么?它们是西红柿。)
(2)询问远处物品:What are those? → They’re + 复数名词.(那些是什么?它们是……。)
课本原句:What are those? They’re boxes for bees.(那些是什么?它们是蜜蜂的盒子。)
3. 易错提示:答句必须用They’re(不能用It’s),因为询问的是“多个物品”。
语法点4:一般现在时(have/has表示“有”,基础)
1. 讲解:本单元用have/has表示“拥有”,主语是第一人称、第二人称或复数时用have;主语是第三人称单数时用has。
2. 句式+课本原句例句
(1)主语是I/we/you/复数名词(如I, you, they, cows):主语 + have ...
课本原句:I have a lot of animals.(我有很多动物。)
They have 10 sheep.(他们有10只绵羊。)
(2)主语是第三人称单数(如he, she, my father, the farm):主语 + has ...
例句:My father has a small farm.(我爸爸有一个小农场。)
The farm has many tomatoes.(这个农场有很多西红柿。)
(3)否定句:主语 + don’t/doesn’t + have ...(本单元重点掌握don’t have)
例句:I don’t have a pig.(我没有一头猪。)
3. 易错提示:第三人称单数(如my father)后面用has,不用have。
