情景导入

💡情景导入 · 周末逛农场

周末,小杭跟着爸爸妈妈去杭州郊区的亲子农场玩。一进大棚,他就指着一串红彤彤的果子问:"Are these tomatoes?"(这些是西红柿吗?)

农场阿姨笑着说:"Yes, they are! Try one, it's sweet."(是呀!尝一个,很甜。)

走到草地上,一群毛茸茸的动物围了过来。小杭又问:"What are those?"(那些是什么?)

"They're sheep!"(是绵羊!)咦,怎么一只羊和一群羊都叫 sheep?

逛农场、认蔬菜、数动物——这一课的复数变化最有意思!

句型与语法

🧩语法讲解 · 问东问西与复数大变身

第一招:问"这些/那些是什么"

  • What are these? (这些是什么?近处)— They're carrots.
  • What are those? (那些是什么?远处)— They're horses.
  • 回答统一用 They're...,注意是复数!

第二招:确认"是不是"——Are these / those...?

  • Are these potatoes? — Yes, they are. / No, they aren't.

第三招:复数大变身(本单元重头戏)

  • 一般情况加 s:carrot → carrots,cow → cows
  • o 结尾加 es:tomato → tomatoes,potato → potatoes
  • 单复数同形:sheep → sheep(一只是 sheep,一百只还是 sheep!)。

听说训练

农场大发现(和同伴问答):

  • A: Welcome to my uncle's farm! (欢迎来我叔叔的农场!)
  • B: Wow, it's so big! What are these? (哇,好大呀!这些是什么?)
  • A: They're green beans. Do you like them? (是豆角。你喜欢吃吗?)
  • B: Yes, I do. Look! Are those sheep? (喜欢。看!那些是绵羊吗?)
  • A: Yes, they are. They're so cute! (是的,它们太可爱啦!)

辨析对比

⚖️易混辨析 · 复数变化三大阵营
  • 规规矩矩加 s:carrots / cows / hens / goats / horses;
  • o 结尾加 es:tomatoes / potatoes——口诀"西红柿土豆是双胞胎,都要加 es";
  • 单复数同形:sheep → sheep——判断一只还是一群,要看前面的 this/these 和后面的动词:This sheep is white.(一只)/ These sheep are white.(一群);
  • 顺带分清一对形近词:sheep(绵羊,卷毛)和 goat(山羊,有胡子),考试爱放一起考。

文化角

🌍文化角 Culture Corner

在澳大利亚和新西兰,sheep(绵羊)比人还多!新西兰大约 500 万人口,绵羊却有 2500 万只,所以人们开玩笑说那里是"骑在羊背上的国家"。

我们杭州周边也有很多亲子农场,比如西溪湿地附近就有农耕体验园。下次去玩时,试着用英语说说看到的东西:Look! Three hens and a goat!——把农场变成你的英语课堂。

易错点

⚠️难点 · 易错点
  1. tomato 复数漏 e:two tomatos ❌ → two tomatoes ✅(potato 同理)
  2. sheep 加 s:three sheeps ❌ → three sheep ✅(单复数同形)
  3. these/those 配单数:These is a carrot. ❌ → These are carrots. ✅(these/those 后面必须跟复数)
  4. 回答用 these:Are these hens? — Yes, these are. ❌ → Yes, they are. ✅

考点

🎯考点提示
  • What are these/those? — They're... 的问答匹配(必考);
  • 名词复数特殊变化:tomatoes / potatoes / sheep(填空题最高频考点);
  • 蔬菜动物词汇拼写:carrot / horse / sheep / green beans(听写重点);
  • Are these...? / Are those...? 的肯定否定回答;
  • How many + 复数名词 的数量问答(常与数字听力结合考)。

诵读 Read Aloud

🎙️短文诵读 · At the Farm(建议背诵)

Last Sunday, I went to a farm near Hangzhou with my parents. The farm is big and beautiful. There are many vegetables. The tomatoes are red. The carrots are orange. The potatoes are big. There are many animals, too. I see ten sheep, five cows and two horses. The sheep are white and cute. I love the farm!

诵读小贴士:这是"参观农场"的标准写话模板——先总说农场大而美,再分说蔬菜和动物,注意 tomatoes、potatoes 的 es 和 sheep 的"原形不变"。数动物时可以掰着手指头读,节奏感满满。
