高频易错点01
(1)This is a green tree.(P42)
颜色类形容词的用法
颜色单词(pink/blue/red/brown/black/white/purple/green/orange/yellow 等)属于形容词,放在名词前面修饰名词,结构为「颜色形容词 + 名词」,用来描述事物的色彩。
冠词搭配:单数可数名词前要根据发音加 a/an,颜色以辅音音素开头就用 a,元音音素开头用 an(比如 an orange butterfly,orange 元音开头用 an;a green tree,green 辅音开头用 a)。
易错点提示
❌ 错误语序:the tree green(形容词不能放在名词后面修饰普通名词)
✅ 正确语序:the green tree(形容词前置修饰名词)
特殊点:口语中可以说 “The tree is green.”(主系表结构,颜色放在 be 动词后作表语),两种句式不要混用语序。
固定场景易错:描述绘画涂色题目时,Colour the tree green.(colour 作动词表 “涂色”,结构:colour + 物品 + 颜色),不要错写成Colour green the tree。
常见搭配示例
前置定语:yellow flowers 黄色的花、purple butterfly 紫色的蝴蝶、white birds 白色的小鸟
主系表:The flowers are yellow. 这些花是黄色的。
涂色指令:Colour the dog brown. 把小狗涂成棕色。

点拨
一、单项选择
1. 答案:B
解析:orange 以元音音素 /ɒ/ 开头,单数可数名词前要用不定冠词an。
2. 答案:A
解析:形容词 green 要前置修饰名词 grass;grass 是不可数名词,不能加 a,C 错误;形容词不能后置,B 错误。
3. 答案:A
解析:colour 在这里作动词,意为 “给…… 涂色”,固定结构Colour + 物品 + 颜色,是涂色题的标准表达。
二、填空
1.a; yellow(yellow 辅音音素开头,用 a,yellow 修饰 flowers)
2.A; green(green 辅音音素开头,用 A,句首首字母大写,green 修饰 tree)
3.a; white(white 辅音音素开头,用 a,white 修饰 animal)
4.a; purple(purple 辅音音素开头,用 a,purple 修饰 butterfly)
高频易错点02
My favourite colour is white. Snow is white.(P43)
颜色的描述与问答
核心句型结构

表达最喜欢的颜色:My favourite colour is + 颜色词.

❌ 错误语序:White is my favourite colour.(小学阶段更推荐使用My favourite colour is...的固定句式,避免主系表结构的语序混淆)
✅ 正确表达:My favourite colour is white.
❌ 单复数错误:Vegetables is green.(vegetables 是复数,be 动词要用 are)
✅ 正确表达:Vegetables are green.
固定搭配拓展

高频易错点04
There are colourful fireworks. (P48)
There be 单复数 + 名词可数性
易错点提示
1. There be 句型单复数匹配规则
There is + 单数可数名词 / 不可数名词:例:There is a big pink firework. / There is dark sky at night.(dark 表昏暗环境,不可数)
There are + 复数可数名词:例:There are four yellow-purple fireworks.
易错坑点:firework是可数名词,日常多用复数fireworks,必须搭配There are,不能错用There is fireworks。
2. 词汇易混辨析
fireworks:复数名词,烟花(常用复数形式);单数firework特指单支烟花
dark:形容词(昏暗的)/ 不可数名词(黑暗),不能直接加 s 变复数
3. 问答句式易错点
问句Do the children like...?的肯定回答用Yes, they do.,再补充原因;描述烟花数量要严格匹配单复数:
❌ There's many fireworks.
✅ There are many fireworks.
